Abstract

The present application provides a liquid cooling module, a control method thereof, and a liquid cooling system applied to a data center. The liquid cooling module includes: a cooling liquid pipe having a cooling liquid pipe inlet and a cooling liquid pipe outlet; A cooler, a pumping mechanism, and a first one-way valve between the pipe inlet and the cooling liquid pipe outlet; the inlet is provided between the outlet of the pumping mechanism and the inlet of the first one-way valve, and the outlet A bypass pipe is arranged between the cooler and the inlet of the cooling liquid pipe; and a bypass valve is arranged on the bypass pipe, and the opening degree of the bypass valve is adjustable. According to the liquid cooling module of the present application, when the heat load in the load circuit is small, it is possible to avoid the shutdown caused by the excessive pressure in the liquid cooling module or the low speed of the pump, and to avoid the situation where there are multiple liquid cooling modules. In the system, the flow of liquid cooling modules crosstalk with each other.

Description

technical field [0001] The present application relates to the technical field of heat dissipation of data center cabinets, in particular to a liquid cooling heat dissipation module, a control method thereof, and a liquid cooling system for data centers. Background technique [0002] With the increasing power of ICT cabinets in computer clusters, the deployment in data centers has become increasingly difficult. Liquid cooling has been deployed in some data centers to solve this problem. In the liquid cooling system, the liquid cooling module (CDU, Coolant Distribution Unit) is a key component, which undertakes the functions of heat dissipation, fluid circulation power, temperature control, etc., and for some businesses, the importance level is high, and liquid cooling needs to reduce failures Scope of influence. Correspondingly, the liquid-cooled pipeline has a ring network design, and the liquid-cooled CDU is also N+1 backup. [0003] However, if figure 1 As shown, the exi...
