The invention relates to a novel battery cooling structure based on coupling of heat pipe and liquid cooling plate, which comprises a battery, a liquid cooling plate and an L-shaped heat pipe, the liquid cooling plate is arranged at the bottom of the battery, the L-shaped heat pipe comprises a vertical evaporation section and a horizontal condensation section, the evaporation section absorbs the heat of the wall surface of the battery main body, and the condensation section transfers heat absorbed by the evaporation section to the liquid cooling plate. The heat pipe is combined with the liquidcooling plate, the heat pipe takes away heat on the wall surface of the battery main body, the heat passes through the evaporation section and the condensation section of the heat pipe and then is taken away through the liquid cooling plate, other energy supplies are not needed in the whole heat dissipation process, and the structure is an efficient and energy-saving cooling mode. The cooling capacity of the liquid cooling plate to the bottom of the battery is not reduced, and the heat dissipation of the wall surface of the battery main body is increased, so that the total heat exchange effect is certainly improved compared with the traditional cooling structure, and the structure can effectively reduce the temperature of the wall surface of the battery, improve the charge-discharge performance of the battery and reduce the influence of reduction of the capacitance of the battery caused by temperature rise.
本发明涉及一种基于热管与液冷板耦合的新型电池冷却结构,包括电池、液冷板和L型热管,所述液冷板设置在电池的底部,所述L型热管包括竖直的蒸发段和水平的冷凝段,蒸发段吸收电池主体壁面热量,冷凝段转移蒸发段吸收的热量至液冷板。本发明通过将热管与液冷板结合,热管带走电池主体壁面的热量,热量经由热管的蒸发段与冷凝段,再通过液冷板将热量带走,整个散热过程不需要其他能源供应,是一种高效节能冷却方式。液冷板对电池底部的散热量没有减少,而增加了电池主体壁面的散热,因此总的换热效果相对于传统冷却结构而言一定得到了提升,该结构能有效降低电池壁面温度,提高电池充放电性能,减少因温度升高而导致电池电容量下降的影响。
