The invention provides a vehicle-mounted charger which comprises a shell, an opening is formed in the top of the shell, and a control circuit board is arranged at the opening; a cooling liquid flow channel is arranged inside the shell, and a liquid inlet nozzle and a liquid outlet nozzle which are communicated with the cooling liquid flow channel are arranged outside the shell; a metal substrate is arranged at the position, located on the outer side wall of the cooling liquid flow channel, in the shell, and multiple rows of patch switch tubes electrically connected with the control circuit board are arranged on the metal substrate; partition plates matched with the side portions of the shell to define a filtering cavity are arranged on the two sides of the cooling liquid flow channel in the shell, a filtering module electrically connected with the control circuit board is arranged in the filtering cavity, and each partition plate comprises an isolation part located between the filtering module and the metal substrate. According to the vehicle-mounted charger provided by the invention, the independently designed filtering module and the metal substrate provided with the patch switch tube are adopted, so that mutual signal interference is reduced, effective separation and shielding are achieved, the product size is also reduced, and the heat dissipation effect is also improved.
本发明提供了一种车载充电机,包括壳体,壳体顶部设置为敞口,敞口处设有控制电路板;壳体内部设有冷却液流道,壳体外部设有与冷却液流道相连通的进液嘴和出液嘴;壳体内部位于冷却液流道的流道外侧壁上设有金属基板,金属基板上设有与控制电路板电连接的多排贴片开关管;壳体内部位于冷却液流道两侧设有与壳体侧部配合围成滤波腔体的隔板,滤波腔体内部设有与控制电路板电连接的滤波模块,隔板包括位于滤波模块与金属基板之间的隔绝部;本发明提供的车载充电机采用独立设计的滤波模块和设有贴片开关管的金属基板,减少相互之间的信号干扰,做到有效的分隔与屏蔽,也减少产品体积,还提升散热效果。
