Thermistor is a kind of sensitive element. There are two kinds of thermistors based on different the temperature, which are PTC and NTC. It has a typical characteristic that it is sensitive on temperature. It shows different resistance value when it is under different temperature. When the temperature goes up, PTC is with higher resistance values while the NTC thermistor is on the opposite. But both of them belong to semiconductor apparatus. Main characteristic of thermistor a.It has very high s...(more)

Multi-stage of TEC

Time: Feb 02 2015    Click: 496

The maximum temperature difference of a single-stage thermoelectric cooler with a standard can reach about 72℃. Some TEC can be stacked together by using mechanical method: the cold side surface of one TEC is installed on the hot side surface of another TEC, so the maximum temperature difference can reach 130℃. This stacking is called the cascade or multi-stage cooler layout. In general, multi-stage cooler has the shape of Pyramid, and a high level volume of TEC is smaller than the low level...(more)

High-Power Laser Diodes

More recently high-power laser diodes operating in the wavelength range of about 0.81.1 micron have been getting much attention due to their widespread applications. These lasers are used in optical pumping of solid-state lasers, such as the Nd: YAG, replacing traditional flash lamp designs. High-power laser diodes are tuned to the absorption band of the dielectric crystal resulting in much more efficient pumping of the laser rod, from which a high-power focused coherent beam of light is emitted...(more)

Thermal pad has good heat conduction ability and high level pressure-tolerant, and it is the substitute of thermal grease. Because of having certain flexibility, it has good bonding between a power device and an aluminum heat sink, so it can achieve the best purpose of heat conduction and heat dissipation. In the industry, thermal pad is also called the thermal silica film, thermal conductive silicone pad, insulating heat conducting sheet, soft cooling pad and so on. As the electronic equipmentc...(more)

The Performances of Thermal Silica

The forms of thermal conductivity silicone are grease and solid. And there are also many different kinds of materials can be competent forapplicationsof the thermal conductivity silica. When producing thermal silica, there are some factors to consider. Thermal conductivity is also known as thermal efficiency. As a goodthermal conductivity material, it must be able to absorb heat quickly, and alsocan radiate heat. We usually use the unit of thermal conductivity to measure the efficiency of therma...(more)

Learning the Key Features of TEC Temperature Controller

TEC (Thermo-Electric Cooler) temperature controllers have some unique and important features that other temperature controllers do not have. One of the key features of TEC controller offers is that it allows the target object reaching the set-point temperature in a short time. Lets use a 202010 (mm) object as an example, driving a TEC with a TEC controller can allow the object reaching the set-point temperature within 5 seconds understand either cooling or heating mode, as the set-point temperat...(more)

The Characteristics of Thermal Silicone Pads

Time: Jan 28 2015    Click: 412

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)

Introduction to Thermal Silicone Pads

Time: Jan 27 2015    Click: 421

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)
