Abstract

The invention provides a wide-temperature-range type efficient liquid cooling circulating temperature control device. The device comprises a main control system, a compressor, a condenser, an expansion valve, a plate type heat exchanger, an air blower, a liquid storing box, a circulating pump, an air cooler, a temperature sensor, a pressure sensor, a first solenoid valve, a second solenoid valve, a third solenoid valve, a fourth solenoid valve, a fifth solenoid valve, a sixth solenoid valve and a seventh solenoid valve. The invention further provides a control method of the wide-temperature-range type efficient liquid cooling circulating temperature control device. According to the device and method, the condensing temperature of a refrigerant in the condenser is lowered down through self-circulating liquid, and thus the refrigerating efficiency under a high temperature environment is increased; a forced air cooling mode is adopted in the low temperature environment, so that the power consumption can be decreased, and the energy can be effectively saved.

Description

Technical field [0001] The invention relates to the technical field of electronic equipment working environment control, in particular to a wide temperature zone high-efficiency liquid cooling cycle temperature control device and a control method thereof. Background technique [0002] As the degree of integration of electronic equipment becomes higher and higher, the heat generation of electronic equipment has increased geometrically, and the inability of heat to be discharged in time will result in low work efficiency of electronic equipment and even burnout of components. The traditional liquid-cooling refrigeration cycle method uses compression refrigeration to reduce the temperature of the liquid, and then transports the low-temperature cold-carrying liquid through an external heat load for a reciprocating cycle, reducing the working temperature of the heat load. But for special industries, in high temperature environments, the discharge temperature and condensing temperature...
