Abstract

The invention discloses an electric vehicle power battery cooling device. The device comprises a mounting plate and an air blower and a battery storage box which are arranged on the mounting plate, wherein the air blower is connected with an air inlet in the upper portion of one side of the battery storage box through an air guiding tube, and an air outlet pipe is arranged at the bottom of the other side of the battery storage box; a water tank is arranged at one side of the battery storage box, a cavity of the water tank is filled with cooling water, one end of the water tank is fixedly connected with the battery storage box, the other end of the water tank is provided with a semiconductor refrigeration sheet and a cooling fan which are used for reducing the temperature of the cooling water in the water tank; a heat conducting rod is arranged in the water tank, the end portion of the heat conducting rod penetrates through the water tank and the sidewall of the air guiding tube and extends into the air guiding tube, and a set of symmetrical meshy heat conducting sheets are arranged at the end portion of the heat conducting rod.

Description

technical field [0001] The invention relates to a cooling device, in particular to a cooling device for a power battery of an electric vehicle. Background technique [0002] When the operating temperature of the battery is too high, it is easy to produce dangerous situations such as explosion. The cooling speed of the existing electric vehicle power battery cooling device is relatively slow, and the cooling effect is not good, which affects the service life of the power battery; the existing electric vehicle power battery cooling device does not have the function of dehumidification, so the power battery is prone to moisture And cause damage, further affect the service life of the power battery. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in the prior art, to provide a power battery cooling device for electric vehicles, which is used to speed up the cooling speed of the power battery cooling device for electric ve...
