With the shrinking volume of electronic component and the development of its performance and speed, the energy consumption of chips is larger and larger. The excessive temperature will make the component subjected to excessive thermal expansion stress, which can result in its structure damage or even the component burning out. Due to the uneven distribution of the chip power density, local hot spots will be generated. According to statistics, more than 55% of electronic equipment failure is due to excessive temperature. Take space telescope for instance. If the operation temperature of CCD and other electronic components is reduced, it can contribute to reduce dark noise, improve sensitivity and ensure detection ability. Therefore, it is necessary for components with thermal consumption as well as the whole system to use appropriate cooling techniques, which can control temperature and can ensure the normal operation of electronic equipment or system.(more)
When thermoelectric module is in the cooling mode, the heat of cooled device transfers into the cold end of TEC and then based on thermoelectric effect, the heat is dissipated by the heat sink. According to the first law of thermodynamics, the cooling capacity is equal to the Peltire effect with heat conduction from the heat flow analysis of the single couple of TEC cold end:(more)

TEC is the abbreviation of thermal electric cooler, which is utilized to cool and heat objects based on Peltier effect. In temperature regulation, TEC has many advantages of high stability, high reliability, no noise, and a simple structure with no moving parts. TEC has been widely used for controlling the temperature of laser system, air conditioner, water heater and computer CPU. However, it still has some shortcomings: low efficiency, low thermal power and high cost.(more)
