AI Technical Summary

Technical Problem

When the server's heat dissipation requirements are very low, the existing cooling distribution unit cannot accurately match the coolant flow, resulting in energy waste and excessive server cooling, which affects the safe operation of the data center.

Method used

A bypass module is introduced into the cooling distribution unit and connected in parallel with the water pump module. The bypass module adjusts the coolant flow rate under low load conditions, and the water pump module adjusts the flow rate under high load conditions, thereby expanding the flow rate adjustment range and ensuring that the flow rate matches the load's heat dissipation requirements.

Benefits of technology

It enables precise adjustment of coolant flow under different load conditions, avoiding energy waste and overcooling, and improving the security and reliability of data centers.

Abstract

The application provides a cold quantity distribution unit, which comprises a cooling liquid pipeline, a heat exchanger, a bypass module and a water pump module; the cooling liquid pipeline is connected between the heat exchanger and a load, and is used for heat dissipation of the load; the bypass module and the water pump module are connected in parallel in the cooling liquid pipeline; the bypass module and the water pump module adjust the cooling liquid flow of the cooling liquid pipeline, the flow value in the adjusting interval of the cooling liquid flow adjusted by the water pump module is greater than the flow value in the adjusting interval of the cooling liquid flow adjusted by the bypass module; the bypass module is started under the condition that the running power of the load is less than or equal to a first power threshold, and the cooling liquid at the inlet of the water pump module is transmitted to the outlet of the water pump module; the water pump module is stopped under the condition that the running power of the load is less than or equal to the first power threshold. The application can adjust the cooling liquid flow to match the heat dissipation demand of the load when the heat dissipation demand of the load is very small, energy waste is avoided, and the applicability is strong.
