Problems solved by technology

[0002] The general car battery pack cooling device uses one method to cool the battery pack. It does not use multiple methods to cool the battery pack at the same time, which reduces the cooling efficiency. The ethylene glycol in the liquid cooling will absorb heat and evaporate. Cooling pump cooling efficiency of ethylene glycol is relatively low, which will cause partially vaporized ethylene glycol to stay in the cooling pipe

Abstract

The present invention discloses a vehicle-used battery pack cooling device, which comprises a box. A placement chamber with a forward opening is arranged in the box; a battery pack is arranged in theplacement chamber; four spring chambers are symmetrically arranged in the left, right, upper and lower parts of the placement chamber; press blocks are slidably mounted in the spring chambers; and springs are fixedly mounted between the press blocks and the spring chambers. A motor starts to drive a power rod to rotate; the power rod rotates to drive a first gear and a third gear to rotate; the first gear and the third gear drive a first transmission rod and a second transmission rod to rotate through a first chain and a second chain; the battery pack is cooled with liquid while it is air-cooled so that the heat dissipation of the battery pack is accelerated and the cooling efficiency is increased; an air-cooling mechanism can cool vaporized ethylene glycol in an liquid cooling mechanism;the process of ethylene glycol from a gaseous state to an liquid state is accelerated; a part of work of a cooling pump is shared; and the situation of partial vaporized ethylene glycol residence in apipe is avoided.

Description

technical field [0001] The invention relates to the field of coolers, in particular to a cooling device for a vehicle battery pack. Background technique [0002] The general car battery pack cooling device uses one method to cool the battery pack. It does not use multiple methods to cool the battery pack at the same time, which reduces the cooling efficiency. The ethylene glycol in the liquid cooling cooling device will absorb heat and evaporate. Cooling pump cooling efficiency of ethylene glycol is relatively low, which will cause partially vaporized ethylene glycol to stay in the cooling tube. Contents of the invention [0003] The object of the present invention is to provide a vehicle battery pack cooling device for overcoming the above-mentioned defects in the prior art. [0004] A cooling device for a battery pack for a vehicle according to an embodiment of the present invention includes a box body, the box body is provided with a placement chamber with an opening f...
