天津继红五金机电厂试制出一种半导体致冷器。这种制冷器是以温差电现象为基础的一门致冷技术,也叫温差电致冷。 它是基于帕尔帖效应原理达到致冷目的的,当N型和P型二个半导体元件组成电偶,并通以直流电时,相应的两个接头就会分别发生吸热和放热现象。电偶接头的吸热和放热决定 Tianjin Following the red metal mechanical and electrical plant trial production of a semiconductor cooler. This refrigerator is based on the temperature difference between the phenomenon of a refrigeration technology, also known as thermoelectric cooling. It is based on Peltier effect principle to achieve the purpose of cooling, when the N type and P type two semiconductor components form a galvanic couple, and through the DC, the corresponding two joints will endothermic and exothermic phenomenon. Thermocouple connector endothermic and exothermic decision
