Thermoelectric cooler (
TEC) is built based on Peltier effect. It is a kind of solid components, which has no pollution, high reliability, small size, rapid cooling, rapid heating and some other characteristics. It has been widely used in electronic, medicine, industry, agriculture and some other fields. However, TEC still has some problems.
1.In order to reach the equivalent cooling efficiency of mechanical compression refrigeration, the material optimal coefficient of TEC is not high, which is the main factor that hinders the development of TEC.
2.There is little research about optimization design of cooling system on cold and hot sides, so it makes the design of TEC in the theoretical calculation stage and the actual operation effect cannot be well guaranteed.
3.With the rapid development of science and technology, the sizes of devices are becoming more and more complex and there are more and more factors needing to be considered. How to solve optimization problems of multi-stage TEC, dissipation problems of small size devices and thermoelectric energy conversion problems are the content of the future research.
