1.前言目前用于汽车发动机及其润滑油机油的冷却和空调器的换热器有若干种类。对于换热器来说,首先要求换热性能要好,因此,目前主要以传热效率高的铜和铝作为换热器材料。冷凝器、蒸发器等很早以前就开始采用铝制的。为了实现散热器的轻量化,目前也正向铝制品发展,同时也开始采用新材料和新工艺。 1. Introduction There are several types of heat exchangers for cooling and air conditioners currently used in motor oils for motor vehicles and their lubricants. For heat exchangers, the first to require better heat exchange performance, therefore, mainly to the heat transfer efficiency of copper and aluminum as a heat exchanger material. Condensers, evaporators and other long ago started using aluminum. In order to achieve the lightweight radiator, aluminum products are also being developed, but also began to adopt new materials and new processes.
