Air tightness detection device for liquid cooling integrated box

Abstract

The invention discloses a liquid cooling integration box air tightness detection device in the technical field of air tightness detection devices, and the device comprises a supporting bottom plate, the left and right sides of the top of the supporting bottom plate are vertically provided with supporting side plates, the tops of the supporting side plates are horizontally provided with a supporting top plate, and the center of the top of the supporting bottom plate is provided with a detection box body. The upper part of the left side wall of the detection box body is communicated with an air pressure detection meter, at the moment, a first air supply pipe is controlled to pressurize the inner cavity of the liquid cooling integrated box body through a second air supply pipe, and meanwhile, whether bubbles are generated in the water body in the inner cavity of the detection box body and whether the pressure value changes are observed; therefore, the air tightness of the liquid-cooled integrated box body is judged, the position of a specific crack is convenient to observe, the detection efficiency is improved, compared with a simple air tightness detection result, the detection result is more visual and clear, the problem is convenient to find and improve, the operation is simple and convenient, and the popularization of the liquid-cooled integrated box body air tightness detection device is facilitated.

Description

technical field [0001] The invention relates to the technical field of air-tightness detection devices, in particular to an air-tightness detection device of a liquid-cooled integrated box. Background technique [0002] In a high temperature environment, especially in hot summer, the battery module on the power tool will release a lot of heat during the charging and discharging process and when used in a high temperature environment, and the heat will accumulate due to the influence of the space. Exhaust, the heat will increase the temperature of the battery module, which is easy to cause damage to the battery. In order to reduce the temperature of the battery module during use, a liquid cooling box is usually provided on the power tool to reduce the temperature of the battery module. [0003] In the production process of the existing liquid cooling box, there may be some gaps in the box that are difficult to see with the naked eye. If liquid leakage occurs during use, it i...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that most of the existing detection devices can only detect whether the airtightness problem occurs in the detection process, but cannot find where the cracks are generated, which has no effect on the production improvement of the product, and cannot simulate a more In the real use environment, the problem of low detection efficiency
