The invention provides a cold and hot separated electric vehicle controller mainboard, and belongs to the field of electrical elements. Comprising a main board and a cold and hot zoning circulation assembly, the cold and hot zoning circulation assembly is correspondingly arranged on the two sides of the main board, the main board comprises a bottom board, a circuit board, an inner partition board and a top board, the cold and hot zoning circulation assembly comprises side fans for air inflow on the two sides, a top fan for suction and exhaust and a heat dissipation frame for air flow exchange, and the circuit board is arranged on the bottom board. Supporting tables are arranged between the bottom plate and the circuit board, the supporting tables are evenly arranged on the bottom plate and are of a cylindrical structure, a plurality of channels are formed between the circuit board and the bottom plate through the supporting tables, a hole groove is formed in the middle of the circuit board, the mesh cover buckle is correspondingly buckled in the hole groove of the circuit board, and sealing filler is arranged on the side edges of the circuit board and the bottom plate. The two cooling liquid tanks are correspondingly arranged on the two sides of the bottom plate, the heat dissipation efficiency of the mainboard is improved, and the situation that the internal temperature is fuzzy and influences the heat dissipation process is avoided.

    本发明提供一种冷热分离的电动车控制器主板,属于电气元件领域。包括主板、冷热分区循环组件,冷热分区循环组件对应置于主板两侧,所述主板包括底板、电路板、内隔板、顶板,所述冷热分区循环组件包括两侧进气的侧风机、抽吸排气的顶部风机、气流交换的散热架,电路板置于底板上,底板和电路板之间设置有支托台,所述支托台均匀置于底板上,支托台为圆柱结构,电路板和底板之间通过支托台形成多股通道,电路板中部设置有孔槽,网罩扣对应扣合置于电路板的孔槽内,电路板和底板侧边缘设置有密封填充物,两个冷却液箱对应置于底板两侧,提高主板散热效率,避免内部温度模糊,影响散热进程。
