美国纽约Ｃｏｒｎｅｌｌ大学的ＦｒａｎｃｉｓＤｉＳａｌｖｏ教授正在开发新型的热电致冷材料,他指出传统的电冰箱所用的典型致冷剂的致冷效率仅有10%左右,而新材料将可提高到30%。在传统的致冷设备中,热是通过诸如含氯氟烃之类流体工作介质来传出的。在热电致冷装置中,通过不 Professor FrancisDiSalvo, Cornell University, New York, USA, is developing new thermoelectric refrigeration materials. He pointed out that typical refrigerators used in traditional refrigerators have a cooling efficiency of only about 10% and new materials can be increased to 30%. In conventional refrigeration equipment, heat is dissipated through a fluid working medium such as a chlorofluorocarbon. In thermoelectric cooling devices, no
