Coupling heat dissipation control method and system of server liquid cooling heat dissipation system

Abstract

The invention discloses a coupling heat dissipation control method for a liquid cooling heat dissipation system of a server. The method comprises the steps that the current cooling liquid temperature T and the current chip temperature Tx are detected; the valve opening degree of a cooling liquid inlet valve is adjusted according to the difference value between the current cooling liquid temperature T and the cooling liquid set temperature Td, so that the flow of the cooling liquid is controlled, and the current cooling liquid temperature T is close to or equal to the cooling liquid set temperature Td; and the rotating speed of a cooling liquid inlet pump is adjusted according to the difference value between the current chip temperature Tx and the chip set temperature Txd, so that the flow of the cooling liquid is controlled, and the current chip temperature Tx tends to be smaller than the chip set temperature Txd. Thus, the valve opening degree of the cooling liquid inlet valve and the rotating speed of the cooling liquid inlet pump are adjusted through the difference value between the cooling liquid temperature and the set temperature and the difference value between the chip temperature and the set temperature, the temperature control precision of a heating part can be improved, and the liquid cooling heat dissipation adjustment control dimension of a server is expanded. The invention further discloses a coupling heat dissipation control system of the server liquid cooling heat dissipation system. The coupling heat dissipation control system has the advantages mentioned above.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a coupling heat dissipation control method of a server liquid cooling heat dissipation system. The invention also relates to a coupling heat dissipation control system of a server liquid cooling heat dissipation system. Background technique [0002] With the development of electronic technology in China, more and more electronic devices have been widely used. [0003] A server is an important part of electronic equipment and a device that provides computing services. Since the server needs to respond to and process service requests, generally speaking, the server should have the ability to undertake and guarantee services. According to the different types of services provided by the server, it is divided into file server, database server, application server, WEB server, etc. The main components of a server include processors, hard disks, memory, system buses, etc., which are s...

Problems solved by technology

[0006] At present, the current server liquid cooling system generally only detects the temperature of the heat-generating components, and then uses negative feedback to control the temperature of the heat-generating components through a single adjustment of the pressure or flow of the cooling liquid. However, the accuracy of this control method is not high. , the system fluctuates greatly, and the energy efficiency effect is relatively low
