LED cooling technology and cooling materials

LED cooling technology and cooling materials

Heat dissipation is a major factor affecting the intensity of LED lighting. Heat sink can solve the problem of heat dissipation of low illumination LED lamps. A heat sink can not solve the 75W or 100W LED lighting cooling problem.
In order to achieve the desired illumination intensity, active cooling technology must be used to solve the heat released by the LED lamp assembly. Some active cooling solutions such as fan life are not high for LED lamps. In order to provide a practical active cooling solution for high brightness LED lamps, the heat dissipation technology must be low energy consumption; and can be applied to small lamps; its life is similar to or higher than the light source.

Cooling method

Generally speaking, in accordance with the way from the radiator to take away the heat, the radiator can be divided into active cooling and passive cooling. The so-called passive heat, is through the heat sink heat source LED light source naturally distributed to the air, the cooling effect is proportional to the size of the heat sink, but because it is naturally distributed heat, the effect of course greatly reduced, often used in those space No demand for the equipment, or for the heat of the parts of the heat dissipation, such as some popular motherboard in the North Bridge also take a passive cooling, the vast majority of take the initiative to heat, active cooling is through the fan and other cooling equipment forced The heat will be sent out of the heat sink, which is characterized by high thermal efficiency, and equipment, small size.

Active cooling, subdivided from the way heat can be divided into air-cooled heat, cooling heat, heat pipe cooling, semiconductor refrigeration, chemical refrigeration and so on. LED cooling technology and cooling materials

Air-cooled air cooling is the most common way of cooling, in comparison, is also cheaper way. Air cooling is essentially a fan that takes away the heat absorbed by the radiator. With the price is relatively low, easy installation and so on. But the environmental dependence is relatively high, such as the temperature rise and overclocking its thermal performance will be greatly affected.

Liquid cool

Liquid cooling heat is driven by the liquid in the pump driven by the heat to take away the radiator, compared with the air-cooled, with a quiet, cooling stability, the advantages of small dependence on the environment and so on. The price of liquid cooling is relatively high, and the installation is also relatively cumbersome. At the same time as installed in accordance with the instructions to install the instructions in order to get the best cooling effect. For cost and ease of use considerations, liquid cooling heat is usually used as a heat-conducting liquid, so liquid-cooled radiators are often referred to as water-cooled radiators.

Heat pipe

The heat pipe is a kind of heat transfer element which makes full use of the heat conduction principle and the rapid heat transfer property of the refrigerant. It conveys heat by evaporation and condensation of the liquid in the fully enclosed vacuum tube, has extremely high thermal conductivity, good isothermal The heat transfer area on both sides of the hot and cold can be arbitrarily changed, can be a long distance heat transfer, can control the temperature and a series of advantages, and heat pipe composed of heat exchanger with high heat transfer efficiency, compact structure, advantage. Its thermal conductivity has far exceeded the thermal conductivity of any known metal. LED cooling technology and cooling materials

The River Thames: A Guide to Barging

The River Thames: A Guide to Barging

The River Thames is the spine, the lifeblood and the main attraction of one of the best-known and historically important cities on the planet. But while the section that flows through London is certainly the most high profile, the 215 miles of the Thames slice England, stretching from the Cotswolds at Cirencester, through rural towns and villages to Oxford, London and finally emptying out into the North Sea.
Historically, the Thames has been a vital trade route right back to Roman times. Today, while the Port of London handles around 10% of the entire country’s commercial shipping, the quieter sections of the waterway appeal to private leisure vessels and barge cruise operators.

 

Built On a River

When the Romans arrived in Britain in AD 43, they settled at the most strategic site on the river to build their city, Londinium. From the port they traded extensively throughout the Mediterranean and also made roads to link the capital with the rest of the country. It was the Romans who built the first bridge to span the river, on the site that would later be the crossing of the city’s famous London Bridge.

Bridges and Locks

The bridges that were built across the Thames have become icons of engineering in themselves. Tower Bridge is one of the most acclaimed, and has been an instantly recognisable landmark of the capital since its construction in 1894. The incredible mechanism that allows for its raising and lowering still functions with perfect precision. Westminster Bridge sits under the shadow of Big Ben and is considered one of the most elegant of all in terms of its architecture. The Millennium Footbridge is the city’s newest, opened in 2000 and crossing the river at St Paul’s Cathedral.

There are 45 locks along the river and each has its own history; some date back to the 1500s while others were variously constructed through the 1700-1800s. While in earlier times weirs were built in order to divert the flow of the water to use in mills, as the traffic increased, many of these were converted or used alongside locks, to allow the passage of vessels to navigate the fall of the river. Today, for those on a barge cruise, navigating the locks is one of the most interesting and anticipated parts of the experience.

Attractions en Route

The beauty of exploring the route of the Thames by barge cruise is the constant accompaniment of scenic views and historical and cultural attractions. Runneymede, the site where King John signed the highly significant Magna Carta document, is a popular disembarkation point. As well as the official monument to the event, the lovely woodlands are filled with wildlife and walking paths.

Windsor Castle is another high profile attraction that can be visited along the river, and the oldest and largest castle in the world lives up to the pomp and grandeur of its reputation (the Queen may even be in residence). At Henley-on-Thames, the renowned River and Rowing Museum celebrates not only the river itself, but also the international sport of rowing for which the town has become globally recognised.

Meandering Through History

The elegant curves of the Thames have defined the history of Britain in so many ways. The privilege of being able to traverse its length on a modern day barge cruise offers a unique insight and a truly memorable way in which to see to the country.

Paul Newman is the Marketing and E-Systems Executive for European Waterways, the UK’s most respected provider of all-inclusive, luxury barge cruise itineraries. Part of a team of experienced barging aficionados, Paul is first in line to endorse the perks of a slow-paced barge cruise to anyone looking for a unique holiday experience.

4 Things to Consider Before Renewing Your Car Insurance

4 Things to Consider Before Renewing Your Car Insurance

Every year, people receive notice from their car insurance provider. For many people to update a car insurance policy is an automatic thing – notices received, checks sent, and completed. Others ignore the notice and the cover will continue. However, this is not automatic for some people especially if you are quite frugal. The problem with the new cover is that it usually comes with a higher rate. So before you do anything or send a check without giving a second thought, here are some things to consider and assess before updating your car insurance:
Renew car insurance three weeks ahead Those who update three weeks in advance generally pay far less than those who update days before and on new policy day. According to a study for ‘This is Money’ by comparison sites, the reason for this is because insurance providers are eyeing people who need a new deal and will most likely pay any premium. Additionally, updating the road ahead of time implies financial caution when buying the day before or on the day itself indicates a greater risk to the insurer.

4 Things to Consider Before Renewing Your Car Insurance

Changes in your coverage When it’s almost time for you to update your car insurance policy, you should step back to consider the amount of coverage you currently have. Many people use minimal coverage, believing that’s all they need. Though it’s hard to think of any unexpected things that might happen in the future, be prepared for it to financially reduce the surprise factor. You should also find out if you are paying for excessive coverage. For example, if you have health insurance, why should you pay an additional premium for uninsured motorist coverage if your health insurance can cover your injury costs?

Optional coverage Another point worth considering is optional coverage. For example, is it feasible to bring collision insurance if you drive an older model and model car? Some drivers cut their collision insurance without much thinking of the real cash value of their car when their car loan was paid.

Switch to another insurance provider Some insurance companies usually charge a higher premium for an extension when logging your claim history. You have the option to switch to another insurance provider. But before you do, make sure you do a comprehensive car insurance comparison. Avoid focusing only on premium rates; Keep in mind important aspects such as corporate financial stability, customer relationships, add-ons, etc. when looking for other insurance providers. 4 Things to Consider Before Renewing Your Car Insurance

Insurers know that a percentage of their clients will not try hard to find different quotes for their insurance policies – whether it’s apathy, disrespect, or they’re really rich. But regularly evaluating your car insurance policies and searching for alternative citations for a better deal not only saves you money; It also helps you keep an eye on the amount of coverage you have and if enough to keep you safe on the road.

The Anatomy of an Archipelago

The Anatomy of an Archipelago

For anyone with an interest in natural history, the group of islands collectively known as the Galapagos Archipelago is one of the most fascinating places on the planet. The region is renowned for its unique wildlife and the vital role it played in naturalist Charles Darwin’s research, from which he developed his revolutionary Theory of Evolution.
While the majority of visitors on guided Galapagos holidays arrive to experience a close encounter with the iconic wildlife, learning a little of the area’s geologic history can enrich the experience even beyond expectation.

 

The Anatomy of an Archipelago

The most common way for an archipelago to form is through constant volcanic activity. (They can also form from continental islands, due to erosion or evaporation of water.) Volcanic archipelagos can form in the ocean and in rivers or lakes as they erupt on beneath the surface of the water. When oceanic, the resulting land masses are known as an “island arc”. In many cases this forms as a result of a “hot spot”, in which parts of the Earth’s crust (tectonic plates) continually shift and create friction.

Where two tectonic plates meet and create a hot spot, magma (red-hot molten rock) can push through the sea floor to create an underwater volcano. As tectonic plates continue to shift over the hot spot, the constant eruptions cause lava to build up and up over millions of years until they emerge from the surface of the ocean to create an island.

In some cases, activity ceases when the tectonic plate eventually moves away from the hot spot. But in others, for example in Hawaii and Japan, the island chains continue to evolve, with many of the volcanoes still active today.

The Geology of Galapagos

The Galapagos Archipelago was formed through the repeated movement of the Nazca tectonic plate over millions of years. As it took place over such a long time period, the eastern islands in the chain are actually millions of years older than some of those in the west. The younger ones, like Isabela and Fernandina, for example, are thought to only be around a few hundred thousand years old, and are still in formation today. Some of the older ones, like San Cristobal and Espanola, may be up to five million years old – still relatively young in the history of the world. With the exception of Isabela (which, as the largest, is made up of six), each island was formed from a single volcano.

Due to their volcanic nature, most of the islands in the chain have a similar conical appearance, but they range from those with very low, gentle slopes to some that soar steeply more than 5,000 feet above sea level. It is this varied of topography that has created the astonishing diversity of habitat that supports the magnificent array of unique wildlife – much of which is endemic.

Discover a Unique Region on Galapagos Holidays

The geology and ecology of this isolated island chain make it one of the most unique places in the world. For those who want to learn more, organised small group Galapagos holidays provide the opportunity to explore this rich, bio-diverse part of the planet in an intimate, educational and truly memorable way.

Humboldt Current: blood from the Galapagos Islands

Humboldt Current: blood from the Galapagos Islands

The uniqueness of life on the Galapagos Islands is well documented and, for nature lovers, a visit to this region can be an inspiring and life-changing experience. For those who embark on the Galapagos wildlife voyage, understanding the reasons behind its extreme diversity can contribute to a deeper appreciation of this remarkable part of the world.
Natural phenomena Humboldt Current: blood from the Galapagos Islands

There is one natural phenomenon that can take great credit for the abundance and diversity of marine and terrestrial animals in the archipelago. The cool Humboldt now comes from Antarctica, driven by strong winds to flow to the west coast of South America and push the cool waters toward the path through the Galapagos Islands. It brings with it the nutrients it collects from dead and rotten objects on the seafloor, and when mixed with the warm Southern Equatorial currents, these nutrients rise from deep to maintain the plankton that form the basis of the food chain on the island. .

This current affects every aspect of life, both on land and around the ocean.

Water Temperature: Some people who visit Galapagos wildlife voyage are stunned by the cold water temperature, due to the Humboldt current. June to December is when the ocean is the coldest, because these months are marked by rising currents. From November to May, the flow is still there, but significantly weaker, allowing warmer waters to reach the islands. Humboldt Current: blood from the Galapagos Islands

Weather Pattern: The current is also responsible for two different seasons experienced in the archipelago: cool winters and warmer monsoon seasons. In the dry months (from June to October), strong trade winds cause currents to rise. Because the waters around the island are cooler, less evaporation, and therefore fewer rain clouds are formed. While Galapagos wildlife cruises can be enjoyed at any time of the year, two seasons can offer a very different experience.

Wild Animals: Even beyond these remote islands, Humboldt’s presence can be felt and credited as “the world’s most productive sea eco system” – responsible for 20% of the world’s amazing marine catch. Every single species – reptiles, mammals, birds, invertebrates or marine – on every single island, including the surrounding waters, is influenced by and dependent on this strong current. Nutrient waters that are brought directly or indirectly provide a source of food that supports large wildlife populations. Humboldt Current: blood from the Galapagos Islands

El Niño Effect

Current current effects may be most clearly visible when nonexistent. During a weather phenomenon known as El Niño, it is attenuated by warmer winds and decreases in air pressure. During these times, which occur cyclically every two to seven years, there is a marked decrease in the activity of local wildlife breeding. There are much fewer fish, and therefore a very large source of food in the archipelago, resulting in large numbers of animals starving to death.

The complex and definitive role played by these cold ocean currents in maintaining the rich biodiversity of the islands is an interesting aspect of one of the most interesting places on the planet. Humboldt Current: blood from the Galapagos Islands
