散热片的表面形状对散热器的散热效果有很大的影响。目前汽车用散热器的散热片大多是用薄铜皮制成,并整齐、稠密地排装于冷却管上。在使用过程中很容易产生倒状和皱折;在修理中(如镶接修理时)也会因修理的需要而将其拆除一部分。散热片弯曲皱折以后,就会使空气流通的通道发生变化,增加流过散热器的空气阻力,使散热效果大大降低。散热
The surface shape of the heatsink has a great influence on the heat dissipation effect of the heatsink. At present, the radiator for automotive radiator is mostly made of thin copper skin, and neatly and densely arranged on the cooling pipe. In the process of using is prone to fall and crease; in the repair (such as when the mosaic repair) will also need to be removed as part of the repair. After the heat sink is bent and folded, the passage of air flow will be changed to increase the air resistance flowing through the heat sink so as to greatly reduce the heat dissipation effect.
