Coupling heat dissipation control method and system of server wind-liquid comprehensive heat dissipation system

Abstract

The invention discloses a coupling heat dissipation control method of a server wind-liquid comprehensive heat dissipation system. The method comprises the steps that the current cooling liquid temperature T, the current main chip temperature Tx and the current auxiliary chip temperature Ty 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 T is close to or equal to Td; The rotating speed of a cooling liquid inlet pump is adjusted according to the difference value between the current temperature Tx of the main chip and the set temperature Txd of the main chip, so that Tx approaches to be smaller than Txd; And the rotating speed of the fan is adjusted according to the difference value between the current auxiliary chip temperature Ty and the auxiliary chip set temperature Tyd, so that Ty approaches to be smaller than Tyd. According to the invention, the temperature control precision of the heating part can be improved, the heat dissipation requirements of the main chip and the auxiliary chip are considered, and the air-liquid heat dissipation adjustment control dimension of the server is expanded. The invention further discloses a coupling heat dissipation control system of the server wind-liquid comprehensive heat dissipation system. The coupling heat dissipation control system has the beneficial effects mentioned above.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a coupled heat dissipation control method of a server air-liquid integrated heat dissipation system. The invention also relates to a coupling heat dissipation control system of the air-liquid integrated heat dissipation system of the server. 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. [0004] In the era of big data, a large number of IT equipment will be centrally...

Problems solved by technology

[0006] At present, the air-liquid integrated heat dissipation system of the current server generally only detects the temperature of the main chip, and uses negative feedback to adjust the pressure or flow of the cooling liquid and the pressure or flow of the cold air. The temperature control of the chip, however, the accuracy of this control method is not high, the system fluctuates greatly, and the energy efficiency is relatively low, ignoring the heat dissipation requirements of the sub-chip
