Description

Technical Field

[0002] With the development of the new energy vehicle industry, the research and development, production and product testing of battery packs, battery controllers and other related equipment have continuously put forward more and more demands on water-cooled temperature control equipment.

[0003] For example, to study and verify the performance of battery packs during charge and discharge, it is necessary to simulate the performance of battery packs and battery controllers under various operating conditions, under different air conditions and at different automotive antifreeze temperatures. Regarding the automotive antifreeze temperature range, the current national standard and industry requirements generally test for temperatures between -40°C and +100°C. Due to the rapid development of this industry in recent years, traditional equipment is unable to meet the various new technical requirements of this rapidly evolving industry.

[0004] High and low temperature cycle test chambers (also known as high and low temperature cycle test chambers, high and low temperature test chambers, etc.) are primarily designed for testing the adaptability of electrical and electronic products, their components, and other materials during storage, transportation, and use in high and low temperature environments. They are generally categorized as programmable high and low temperature test chambers (touch screen / keypad) and single-point high and low temperature test chambers.

[0005] Existing high and low temperature cycle test chambers are often located in small environments with slow air circulation. However, since the high and low temperature cycle test chambers generate a lot of heat during operation, a large amount of heat is easily accumulated around the high and low temperature cycle test chambers in an environment with no air circulation, resulting in untimely heat dissipation of the high and low temperature cycle test chambers, which is prone to circuit burning problems, thereby causing material waste.

[0006] High and low temperature test chambers are primarily used to conduct high and low temperature tests on product components and materials, as well as to test the adaptability of products to storage, transportation, and use in low-temperature environments. Existing high and low temperature test chambers generally have only a single test chamber and cannot promptly change the internal environment during heating, pressurization, or refrigeration tests. Improper testing can lead to the risk of fire or explosion, posing a certain risk.
