近来,由于排气净化装置以及汽车冷气装置、自动变速机等装置的增加,又由于高速公路的建成,连续高速、高负荷的运转颇为普遍。因此,对于冷却系统的要求日益强烈起来。散热器为适应这样的要求,首先从散热片形状开始,在构造方面也作了相当显著的改进。但是,作为它的基础乃是实验的处理,而这方面往往缺乏理论的、定量的分析研究。本文为弥补这方面的不足,在空气侧应用Pohlhaussen的实验式,在水侧应用Abramowitz理论的计算结果,考虑到散热片的热传导以及百叶窗的切口,导入了散热器散热量的方程式。再从三种散热器的试验结果,求出试验公式。求出的试验公式能够应用于一般的散热器,所以,在设计研究阶段,会得到广泛应用。
Recently, the continuous high-speed and high-load operation has become widespread because of the increase of exhaust gas purification devices, air-conditioners, automatic transmissions and the like, and the construction of expressways. Therefore, the requirements for the cooling system are getting stronger day by day. In order to meet such a requirement, the heat sink starts with the shape of the heat sink, and also makes a considerable improvement in the structure. However, it is based on the experimental treatment, but in this area often lack of theoretical and quantitative analysis. In order to make up for this deficiency, Pohlhaussen’s experimental formula is applied on the air side and Abramowitz’s theory is applied on the water side. Considering the heat conduction of the heat sink and the incision of the shutter, the heat dissipation equation of the heat sink is introduced. Then from the three radiator test results, find the test formula. The test formula can be applied to the general radiator, so, in the design and research phase, will be widely used.
