The invention relates to a charger, and discloses a transformer sinking type vehicle-mounted charger which comprises a lower shell, an upper shell covering the lower shell, a transformer installed on the upper shell and a lower circuit board installed in the lower shell, and first cooling fins are arranged on the outer end face of the upper shell; the groove bottom of the upper shell is provided with a first installation groove protruding towards the first cooling fins, the first installation groove is filled with heat conduction glue, the transformer is fastened in the first installation groove, the height of the transformer is a, the depth of the first installation groove is b, b is larger than a/2 and smaller than a, a first protruding block corresponding to the first installation groove is formed on the outer end face of the upper shell, and second cooling fins are arranged on the periphery of the first protruding block. Most of the transformer extends into the first mounting groove and is fastened through heat-conducting glue, so that on one hand, the stability of the transformer in the upper shell is good; on the other hand, most heat generated by the transformer is directly transmitted to the shell through the heat-conducting glue, heat transmission is fast, and the heat dissipation effect of the vehicle-mounted charger is good.
本发明涉及充电机,公开变压器下沉式的车载充电机,包括下壳体、盖合在下壳体上的上壳体、安装在上壳体上的变压器、安装在下壳体内的下电路板,上壳体的外端面设有第一散热片;上壳体的槽底设有向第一散热片方向凸起的第一安装槽,第一安装槽内填满导热胶并将变压器紧固其中,变压器的高度为a,第一安装槽的深度为b,a/2<b<a,上壳体的外端面形成与第一安装槽对应的第一凸块,第一凸块四周都设有第二散热片。变压器的大部分伸入到第一安装槽内并通过导热胶进行紧固,变压器在上壳体内一方面稳定性好;另一方面变压器产生的热量大部分都通过导热胶直接传递给壳体,热量传递快,车载充电机的散热效果好。
