本发明涉及汽车散热器技术领域,具体为一种汽车全铝水箱散热器。
汽车水箱又称散热器,是汽车冷却系统中主要机件;功用是散发热量,冷却水在水套中吸收热量,流到散热器后热量散去,再回到水套内循环,达到调温。是汽车发动机的组成部分。水箱是水冷式发动机的重要部件,作为水冷式发动机散热回路的一个重要组成部件,能够吸收缸体的热量,防止发动机过热由于水的比热容较大,吸收缸体的热量后温度升高并不是很多,所以发动机的热量通过冷却水这个液体回路,利用水作为载热体传导热,再通过大面积的散热片以对流的方式散热,以维持发动机的合适工作温度。对汽车水箱散热往往采用全铝水箱散热器对水箱进行散热。
但现有的汽车全铝水箱散热器,在水槽上需要焊接有进水道和出水道,来进行水循环,在焊接进水道和出水道时需要进行二次焊接,导致产品外观不齐整,水槽与散热管的装配精度较低,易产生虚焊问题,同时散热器受热膨胀产生一定的应力,产品使用一段时间后会产生微渗漏缺陷的问题。鉴于此,我们提出一种汽车全铝水箱散热器。
