Technical Problem
[0002]电动汽车的空调制热主要采用高压液体加热器进行加热，液体加热器内部设有电阻加热器，电阻加热器通过IGBT进行控制，IGBT能精确的控制温度，但是IGBT发热量较大，需要可靠的散热，如中国专利CN110053453A公开的一种新能源汽车用PTC液体加热器，其所述IGBT模块通过绝缘螺钉与电路板安装腔室内壁贴合固定，通过绝缘螺钉保证IGBT模块和电路板安装腔室内壁紧密贴合，有助于将IGBT模块热量快速传递给电路板安装腔室内壁，这种方式散热效果较差
Benefits of technology
本实用新型提供的一种高压液体加热器IGBT散热结构通过液体加热器内部的液体对IGBT进行散热，散热效果好，并且能够对液体进行加热，实现节能，降低能耗。
