The invention provides an automobile and a vehicle-mounted charger, the vehicle-mounted charger comprises a shell, a heat dissipation pipeline, a printed circuit board and a plurality of semiconductor field effect transistors, a storage groove is formed in the shell, the printed circuit board is arranged in the storage groove, the printed circuit board and the groove bottom of the storage groove are oppositely arranged, and the semiconductor field effect transistors are arranged in the storage groove. At least part of the heat dissipation pipeline is detachably arranged on the printed circuit board; at least part of each semiconductor field-effect tube is fixed on the side wall of the heat dissipation pipeline, and a pin of each semiconductor field-effect tube is welded on a corresponding installation position of the printed circuit board. Compared with a traditional vehicle-mounted charger, the vehicle-mounted charger provided by the embodiment of the invention has the advantages that the semiconductor field effect transistors and the printed circuit board are independently arranged relative to the shell, so that the alignment process of the pin of each semiconductor field effect transistor and the corresponding mounting position on the printed circuit board is convenient and fast, and the production efficiency of the whole vehicle-mounted charger is improved.
本申请提供一种汽车及车载充电机,车载充电机包括壳体、散热管道、印刷电路板以及多个半导体场效应管,其中,壳体上形成有收纳槽,印刷电路板设置在收纳槽内,且印刷电路板与收纳槽的槽底相对设置,散热管道的至少部分可拆卸设置在印刷电路板上;每个半导体场效应管的至少部分固定在散热管道的侧壁上,每个半导体场效应管的管脚均焊接在印刷电路板相应的安装位上。相比于传统的车载充电机,本申请实施例的车载充电机因半导体场效应管与印刷电路板相对于壳体独立设置,使得每个半导体场效应管的管脚与印刷电路板上相应的安装位的对位过程方便快捷,从而提高了整个车载充电机的生产效率。
