There are many kinds of heat sinks. In the view of manufacture, air cooled heat sinks can be divided into nano imprint lithography fins, extrusion heat sinks, casting heat sinks, folding heat sinks, improved casting heat sinks, forging heat sinks, cutting heat sinks, mechanical processing heat sinks and so on.(more)

As the active area of the LED chip is small and its working current is big, the operating temperature of the LED ship can increase in a short time. The rise of pn junction temperature of LED can make the optical output power decrease, accelerate the aging of a chip, and shorten the service life of the device. With the rise in junction temperature, the LED wavelength will have “red shift”. (The drift visual effect of the orange and amber LED is more obvious). So in view of adverse effects of color drift in the practical application, the thermal design will limit the highest junction temperature. In the high power LED cooling channel, the heat radiating substrate is the key link between internal and external cooling channel. It has the following functions at least.(more)

Each one has its specific temperature. For example, my temperature is 36.5℃. If my temperature changes more than 0.1℃, I will get sick. Just like people, laser also has the specific temperature when it is working. If the temperature of laser changes more than 0.1℃, it will not work normally, and we cannot get the result what we would like to have. So we need to control the laser’s temperature seriously. We offer you the best devices to control the laser temperature. (more)

Because of LED's advantages, LED is mainly used in the following aspects currently(more)

Heat sinks are a device which is used to dissipate heat of electronic elements in electrical appliances. There are many kinds of heat sink materials. The following describes are about the aluminum, copper and combinative radiation fins of copper and aluminum.(more)

Although the two cooling systems comply with the same thermal dynamics, a TEC has many obvious advantages: simple structure, small volume, light weight, high reliability, long service lifetime, no noise, small power consumption, low cost and so on. What’s more, there is no need for TECs to fill chemical consumables, which the mechanical cooling method needs. Because of no moving parts, there is no wear and tear for TECs. Thus TEC is an ideal cooling method, which can gradually take the place of the mechanical cooling method when cooling many components (such as CCD).(more)

In practical applications, TEC can sustain work through continuous heat change of heat exchanger and cold and heat source. When the system works, the heat density of cold and hot ends can be up to 104W/m2, so effective operation is strongly dependent on heat transfer performance of cold and hot end. The heat dissipation of the cold end is more important than the hot end’s. Suppose the heat dissipating capacity of the cold end is q1, the heat dissipating capacity of hot end is q2 and the electric power consumption of the system is w0. After the TEC is connected to a power supply, the cold end continuously absorbs q1, which is cooling capacity. This part of the heat and electro-thermal consumption need to be dissipated from the hot end together, which can ensure the normal work of TEC and make TEC play an effective role.(more)

In this paper, the air cooling method of TEC is mainly introduced.(more)

In thermo-electric cooling system, the installation of TECs is very critical. Basic principles should be abided by during installation, or it may result in bad performance and reliability. There are a few factors to be considered in designing and installing the thermo-electric cooling system, as below.(more)

In general, selecting the size of TECs depends on the area of chips, but not bigger than that. Additionally, TEC has a certain thickness, which is put between chip and heat sink. If it is too thick, it will be hard to fix.(more)
