Semiconductor testing equipment is an electronic measuring instrument used in the field of electronics and communication technology. Semiconductor testing equipment generates a large amount of heat during use, and requires a liquid cooling system to dissipate heat and cool the equipment to ensure its normal operation. Semiconductor testing equipment has very high requirements for liquid cooling systems. Traditional air-cooled systems have low heat transfer efficiency, poor heat dissipation effect, low reliability, and poor temperature control accuracy, which far cannot meet the heat dissipation needs of semiconductor testing equipment. Therefore, it is urgent to provide a semiconductor testing equipment liquid cooling system to solve the above problems.
