自从大功率晶体管问世以来,散热器获得了迅速的发展,各种新型的散热器不断涌现。现在,散热器已由当初的最简单的板式散热器,发展到今天的多品种、多形式、多功能的散热器。据估计,仅各种式样的型材散热器就不下数十种。型材散热器结构简单、制造方便、成本低,而且可根据需要任意切取。但是,型材做热器结构不够合理,因为这种散热器两肋 Since the advent of high-power transistors, the heat sink has gained rapid development, and various new radiators continue to emerge. Now, the radiator has been the simplest form of the original radiator, today’s multi-species, multi-form, multi-functional radiator. It is estimated that only a few styles of profile radiators do not under dozens. Profiled radiator structure is simple, easy to manufacture, low cost, and can be arbitrarily cut according to need. However, the profile of the heater structure is not reasonable, because this radiator two ribs
