One or more embodiments of the invention provide a heat dissipation device for an electric vehicle charging pile, the heat dissipation device comprises an isolation cavity, a fan is arranged at an airinlet of the isolation cavity, a heat conduction carrier is arranged, a heat conduction main body is arranged in a pile body, a heat conduction head penetrates into the isolation cavity, and a ventilation channel is formed in the heat conduction head. An air guide channel is fixed to the side, close to the air outlet, of the ventilation channel in an attached mode, a positive-pressure air openingis formed in the bottom end of the isolation cavity, a negative-pressure air opening is formed in the bottom end of the air guide channel, and therefore heat in the pile body can be conducted throughthe heat conduction carrier, and cold air blown in by the fan passes through the ventilation channel, thereby realizing cyclic heat conduction and heat dissipation; meanwhile, due to the fact that the air flow speed at the ventilation channel is increased, negative pressure can be generated at the negative pressure air port to adsorb hot air brought out of the pile body, positive pressure is relatively generated at the positive pressure air port, blown-in cold air partially flows into the pile body, and therefore circulating cold and hot air exchange heat dissipation is formed.
本说明书一个或多个实施例提供一种电动车充电桩用散热装置,包括隔离腔,隔离腔的进风口处设有风扇,并设置有导热载体,其中导热主体设于桩体内,导热头部贯穿入隔离腔内,导热头部上开设有通风通道,且朝向出风口方向的内径逐渐缩小,通风通道靠近出风口的一侧贴合固定有导风通道,隔离腔底端开设有正压风口,导风通道底端开设有负压风口,从而桩体内热量可经由导热载体传导,且风扇吹入的冷空气经由通风通道,以实现循环热传导散热,同时由于通风通道处气流流速增大,从而在负压风口处可产生负压,以吸附带出桩体内的热空气,正压风口处相对产生正压,吹入的冷空气以部分流入桩体内部,由此形成循环的冷热空气交换散热。
