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. No pollution and rotating member. It can’t produce turn effect. There is no slide part, which is a solid part. There is no noise and shake. It has a long life and simple installing.
2. There are two kinds of function of semiconductor thermoelectric cooler. Not only refrigerate them, but also make it warm. It has little refrigeration effect, but much warm effect. So using a slice pieces can replace that separate heating system and cooling system.
3. Semiconductor Thermoelectric Cooler Module is a slice of change about electricity. Through controlling the electricity, it will control the temperature precisely. Through adding the temperature test and control method, it is easy to show control the action and distance of the computer. It’s easy to control automatically.
4. Semiconductor Thermoelectric Cooler Module has little thermal inertia. It becomes refrigeration and heating soon. On the condition that dissipate well in the heat side and there is no load in the cold side, it can achieve the temperature difference within one minute when it is power on.
5. The reverse use in Semiconductor Thermoelectric Cooler Module is producing electricity by the temperature difference. And Semiconductor Thermoelectric Cooler often applies to powering generation at a middle and low temperature.
6. The element of Semiconductor Thermoelectric Cooler Module has a little power. If put them together. Using the same kind of them, and put them in parallel then form a system of thermoelectric cooler, the power will be very huge. So the power can get the range of liwatt or myriawatt.
7. The range of the Semiconductor Thermoelectric Cooler module is from -90℃to 130℃.
Application area
Through the above analysis, the apply fields range of Semiconductor Thermoelectric Cooler module is refrigeration and heating and generating electricity, among those the refrigeration and heating are very popular. There are some aspects as the below.
1. Military: Missile radar, submarine, detect of infrared ray, and the system of GPS.
2. Medical: Cold trap, cold box, cold trough, the test equipment electricity low temperature, all kind of middle temperature and high or low temperature experiment module.
4. Special equipment, the low temperature test equipment oil products, the low temperature test equipment of biochemical products, the box of bacterial culture, appear the image groove of middle temperature, computer and so on.
5. Daily life, air-condition, hot and cold boxes, water dispenser, electronic refrigerator and so on
