Liquid cooling module, control method thereof and liquid cooling system for data center

Abstract

The application provides a liquid cooling module, a control method thereof and a liquid cooling system applied to a data center. The liquid cooling module comprises a cooling liquid pipeline with a cooling liquid pipeline inlet and a cooling liquid pipeline outlet, a cooler, a pumping mechanism, a first one-way valve, a bypass pipeline, and a bypass valve. The cooler, the pumping mechanism, and the first one-way valve are sequentially connected between the cooling liquid pipeline inlet and the cooling liquid pipeline outlet in series. The inlet of the bypass pipeline is arranged between an outlet of the pumping mechanism and an inlet of the first one-way valve, and the outlet of the bypass pipeline is arranged between the cooler and the cooling liquid pipeline inlet; and the bypass valve is arranged on the bypass pipeline, and the opening degree of the bypass valve is adjustable. According to the liquid cooling module, under the condition that the thermal load in the load loop is small, downtime caused by too large pressure in the liquid cooling module or too low rotating speed of the pump can be avoided, and mutual crosstalk of flow of the liquid cooling modules in a system with the multiple liquid cooling modules is avoided.

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...
