The high and low-temperature liquid cooling test machine is precision testing equipment that integrates high temperature, low temperature, rapid temperature change, and liquid cooling/heating. It is mainly used to simulate product performance testing in extreme temperature environments. Its core function is to quickly transfer heat through liquid media (water, ethylene glycol solution, silicone oil, etc.), achieving precise temperature control of the measured substance (typical temperature range: -45℃ to +85℃). It is widely used in high-tech fields such as new energy, semiconductors, aerospace, etc. With the rapid development of new energy and semiconductor industries, efficient, intelligent, and environmentally friendly high and low-temperature liquid-cooled testing machines will become the mainstream of the industry, helping enterprises shorten research and development cycles and improve product reliability.
