Abstract
Thermal dissipation problem has become an issue as the size of products shrunk down. In the limited space, the performance of signal transmission in high density circuitry can be improved under current development. However, more and more heat was generated by itself, and which becomes a bottleneck to make technology going down. Traditional cooling methods, such as heat sinks or fans, can’t keep such electrical elements at stable temperature. Therefore, thermoelectric cooler is a good candidate not only on upholding a stable temperature but also removing the heat generated from chips. The energy, such as petroleum, coal, coal gas, etc., will exhaust one day. The thermoelectric power generator has the advantages of environmental protection and energy technology. It can generate electric energy from the useless heat by thermoelectric effect. This paper mainly relies on the thermoelectric legs design with different geometry and size to analyze the performance of thermoelectric element.
