Cooling liquid blowing device for testing automobile battery assembly

Abstract

The invention discloses a cooling liquid blowing device for testing an automobile battery assembly, relates to the technical field of automobile battery testing, and mainly aims to solve the problems that the internal pressure intensity of a cooling blowing device is unstable and the backflow of cooling liquid is influenced during existing automobile battery testing. The device comprises a mounting shell, a mounting groove is formed in the mounting shell, batteries are evenly arranged in the mounting groove, a cooling groove is formed in the top of the mounting groove, the cooling groove is horizontally attached to the upper side of the mounting groove, stopping blocks are evenly arranged in the cooling groove, a draught fan is arranged on the side edge of the cooling groove, the fan is connected with an air guide pipe, an air outlet is formed in the end of the cooling groove and connected with the air guide pipe, the stopping blocks are obliquely arranged leftwards, a pressure stabilizing cylinder is arranged on the left side of the cooling groove, the left end of the cooling groove is horizontally connected with a backflow pipe, the backflow pipe is connected with a cooling box, and cooling liquid is injected into the cooling box.

Description

technical field [0001] The invention relates to the technical field of automobile battery testing, in particular to a cooling liquid purging device for automobile battery assembly testing. Background technique [0002] As the energy storage element of the electric vehicle, the performance of the power battery directly affects the performance of the electric vehicle. In the vehicle working mode, when the temperature of the external environment and the battery assembly is high or low, the cooling / heating system will cool down or heat up the battery assembly, so as to ensure that its performance will not be greatly affected. In order to truly simulate the working environment of the battery assembly in the real vehicle state, when testing the performance of the battery assembly in the laboratory, it is necessary to add a liquid cooling or heating system to adjust its temperature. [0003] Most of the liquid cooling systems currently used in the laboratory use the liquid purge f...

AI Technical Summary

Problems solved by technology

[0003] Most of the liquid cooling systems currently used in the laboratory use the liquid purge function to increase the cooling rate. The existing liquid purge device will cause the air pressure inside the device to be unstable during the cooling process. The medium coolant will enter the coolant storage tank together with the purged air, which will cause the air pressure in the storage tank to rise, and the return flow of the coolant will be easily blocked
