The Characteristics of Thermal Silicone Pads

Time: Jan 28 2015    Click: 441

There are many characteristics of thermal silicone pads, such as certain flexibility, excellent insulation and compressibility, natural surface tack and so on. The silicone pads are specially produced for the design proposal of transferring heat by using the gap. The thermal silicone pad can fill in gaps and transfer the heat between heating part and radiating part. At the same time, it also plays an insulation, sealing, damping effect. Whats more, the thermal silicone pads can meet the design r...(more)

Thermalsilicone pad is a heat transfer mediumto reduce thermal contact resistance between the heat source surface and contact surface of radiator parts. In the industry, it is also called the thermal silica films, thermal conductive silicone pads, soft cooling pads and so on. As the electronic equipment continually makes more and more powerful function integrate into smaller and smaller components, the temperature increasing will lead to equipment running slowly, device fault, confined space and...(more)

But some usual semiconductor often is made up of Copper, aluminum or other metallic conductor and two pieces ceramic chip like sandwich biscuit to press something from both sides. The ceramic chip must be heat and conduction well. See the following the picture. 3 .The technology application of Thermoelectric Cooler Semiconductor Thermoelectric Cooler is a special kind of cold source. There are some superiority and characteristic. 1.It needs not any refrigerating fluid. And can be work continuous...(more)

The Thermoelectric Cooler is also called Semiconductor refrigeration module, Peltier, etc. . Because of there are two sides, one side absorbs heat, and the other side dissipates heat. Its effect is heat conduction. It does not produce heat by itself. So it is called Refrigeration piece or thermoelectric cooler module. 1.Summary Propaedeutic 1.Peltier effect The conceptual structure of Peltier effect is very simple. When the current goes through the thermal couple, one of the nodes dissipates h...(more)

Thermoelectric cooler (TEC), which was first found by Peltier in 1834, is a semiconductor material as the foundation, and it can be used as electronic components of a small heat pump. Through loading a low DC voltage on both ends of the TEC, the heat will move from one side of the element to the other. At this time, the temperature of one side of TEC will be reduced, and the other side temperature will rise. It is worth noting that, as long as the direction of the current is changed, the directi...(more)

There are many kinds of laser, such as solid, gas, liquid, semiconductor, dyeslaser, etc.. (1)Solid state laser is generally small and rugged, and high power of pulse radiation. The application range is wide. Nd: YAG laser is one of solid-state laser. Nd(nd) is a kind of rare earth element, and YAG stands for yttrium aluminum garnet, whose the crystal structure is similar to that of ruby. (2)Semiconductor laser has the advantages of small volume, light weight, long service life, simple structure...(more)

As semiconductor laser has the advantages of small size, simple structure, high electro-optical efficiency, long service life, easy modulation and low price, so it has a wide range of applications. In optical fiber communications, which have become the mainstream of modern communications, semiconductor laser is the only practical light source.Now, it is the fastest growing and the most important light source in the optical communication field. In laser ranging, semiconductor laser rangefinderhas...(more)

Basic Theory of Semiconductor Laser

Time: Jan 21 2015    Click: 373

Semiconductor laser is also known as laser diode (LD). As early as in 1953, in an unpublished manuscript, John Von Neumann was the first to discuss the possibility of stimulated emission produced in the semiconductor. He considered that stimulated emission can be achieved through the injection of minority carriers to the PN junction, and the transition rates between two Brillouin zones were calculated. After summing up this theory, Bardeen believed that through a variety of methods disturbing co...(more)
