Device and method for testing blasting performance of liquid cooling plate

Abstract

The invention relates to the technical field of electric vehicle battery pack liquid cooling heat dissipation, in particular to a device and method for testing the blasting performance of a liquid cooling plate. The device comprises a water supply tank, a water pump, a first one-way valve and a buffer tank which are sequentially connected through pipelines, and the buffer tank is connected with a water outlet pipe and connected with a sample to be blasted through the water outlet pipe; a gas-liquid pressurizing pipeline is connected between the water supply tank and the buffer tank in parallel; the water outlet pipe is connected with a pressure sensor, a PLC (Programmable Logic Controller) and a pressure relief pipeline; a pressure relief valve is arranged on the pressure relief pipeline; according to the device and method for testing the blasting performance of the liquid cooling plate, the buffer tank is filled with water in the water tank through the compressor, after the buffer tank is filled with the water, the gas-liquid booster pump starts to work, pressurization is slowly started according to the incremental pressure set on the PLC, and therefore the sensor can capture more accurate numerical values more timely, and meanwhile, the situation that the product is instantly blasted and thrown out due to overlarge pressurization, and experimenters and equipment are injured can be avoided.

Description

technical field [0001] The invention relates to the technical field of liquid cooling and heat dissipation of electric vehicle battery packs, in particular to a device and method for testing the blasting performance of a liquid-cooled plate. Background technique [0002] With the continuous increase of energy consumption and the increasingly serious problem of environmental pollution, green environmental protection has become the basic national policy of economic development in all countries in the world. Under this background, new energy vehicles are developing rapidly, and the liquid cooling plate will become the core component of the battery pack. It directly affects the temperature uniformity and timely heat dissipation of the battery in the battery box, and also affects the service life, life, weight, and battery life of the battery. One of the important factors of mileage, so the performance of the liquid cold plate directly affects the performance of the entire car. ...

Problems solved by technology

[0003] At present, there is no strength test for the performance of the liquid cooling plate in the industry. The original method is to directly force the pressure (water or air) to directly explode the product through the pressurization of the compressor, which will cause the product to break instantly. On the one hand, it cannot be guaranteed. The accuracy of the test results, on the other hand, cannot guarantee the safety of the testing process

[0004] Patent 202020762422.3 discloses a new energy vehicle battery pack liquid cold plate burst pressure test device, which discloses that the water outlet of the water storage tank is connected to the water inlet of the main water pipe through a water pipe, and the water pipe is provided with a second A one-way valve, the pressurized output port of the gas-liquid booster cylinder is connected to the water inlet of the main water pipe through a water pipe, and a second one-way valve and a pressure sensor are installed on the main water pipe, and the second one-way valve is located at On the front side of the pressure sensor, the test method in this patent is in the process of pressurized blasting, the water pipe needs to bear a very large pressure and there are no protective measures, so there is a safety risk to a certain extent
