The invention relates to a vehicle-mounted domain controller, and the controller comprises a housing which is provided with an accommodation cavity; the bottom cover is connected with the housing and is used for sealing the open surface of the housing; the mother board is fixed on the bottom cover; the daughter board is fixed on the inner end wall of the accommodating cavity and is connected and interacted with the mother board through a plug; a heat dissipation system; an extending cavity is further formed in the side wall of the heat dissipation mounting part, and driven fan blades are rotationally connected into the extending cavity. The antenna is compact and reasonable in structure and convenient to operate, the heat dissipation installation part extending to the containing cavity is arranged on the cover shell, the heat dissipation system is installed in the heat dissipation installation part, the daughter board, the mother board and the antenna are separated through the heat dissipation installation part, mutual heat influence and electromagnetic interference are reduced, and the heat dissipation effect of the daughter board, the mother board and the antenna is improved. Meanwhile, heat generated by the daughter board, the antenna and the mother board can be better taken away through the heat dissipation system, the heat dissipation effect is further improved, the heat dissipation effect on the daughter board and the mother board is further improved through the driven fan, and the overall structure is high in temperature and space utilization rate.

    本发明涉及车载域控制器,包括罩壳,其上开设有容置腔;底盖,其与罩壳连接用于封闭罩壳的敞口面;母板,其固定于底盖上;子板,其固定于容置腔的内端壁上,且通过接插头与母板连接交互;散热系统;所述散热安装部的侧壁上还设置有延伸腔,延伸腔内转动连接有从动扇叶。本发明结构紧凑、合理,操作方便,通过在罩壳上开设有延伸至容置腔的散热安装部,散热安装部内安装散热系统,通过散热安装部将子板、母板和天线隔开,减少相互的热量影响和减少电磁干扰,同时通过散热系统能够更好的带走子板、天线、以及母板产生的热量,进一步提高散热效果,再通过从动风扇更进一步的提高对子板和母板的散热效果,而且整体结构温度,空间利用率高。
