Abstract

The invention discloses a peak-clipping closed circulating pure water cooling system. The system comprises an auxiliary circulation loop and a refrigerating circuit; the auxiliary circulation loop is connected with the closed circulating pure water cooling system through a three-way valve; the auxiliary circulation loop can carry out heat exchange with the closed circulating pure water cooling system; the refrigerating circuit is connected with the auxiliary circulation loop and carried out heat exchange with the auxiliary circulation loop; and the refrigerating circuit is connected with an air cooler and carries out heat exchange with the air cooler. According to the peak-clipping closed circulating pure water cooling system provided in the invention, the design temperature can be obviously lower than a local limiting temperature; the structure is compact; a using amount of an air heat exchanger can be reduced; a design capacity of the air cooler can be fully utilized; and costs are reduced; therefore, an application range of the closed circulating pure water cooling system can be expanded.

Description

technical field [0001] The invention relates to a closed circulating pure water cooling system for high-power power electronic devices. Background technique [0002] The current high-power power electronic device cooling circulating water system usually adopts the air-cooling method of a closed circulation system and a radiator for heat dissipation. Specifically, the heat brought out by the circulating water is transferred to the air cooler, and at the same time, the peripheral fan blows the heat away with the wind. However, the circulating water temperature changes with the ambient temperature. On the one hand, as the ambient temperature changes, the circulating water also changes periodically. From the point of view of the design temperature, it is basically determined by the peak temperature point that occurs locally. In fact, the temperature in various places varies greatly, and this method can only be applied to environments where the temperature difference does not ...
