Composite heat management system for data center cabinet with server being additionally provided with loop heat-pipe heat exchanger and cross-flow fan

Abstract

The invention discloses a composite heat management system for a data center cabinet with a server being additionally provided with a loop heat-pipe heat exchanger and a cross-flow fan, and belongs tothe field of efficient heat dissipation of data centers. The problem of heat accumulation of a server in a machine room is solved through a heat dissipation mode of combining a loop heat pipe and thecross-flow fan. The system mainly comprises a first server (1-1), a first mainboard (2-1), a first loop heat-pipe evaporation section (3-1), a first loop heat-pipe steam pipeline (4-1), a first loopheat-pipe liquid pipeline (5-1), a first loop heat-pipe condensation section (6-1), a server cabinet (7), a slot air port (8), a cross-flow fan (9), a first loop heat-pipe heat exchanger (10-1) and the like. The heat of a mainboard in the server is led out through the loop heat pipe, the heat is taken away by the introduction of the external air through the cross-flow fan, thereby reducing the local hot spots in the server, improving the heat exchange performance, and improving the system safety.

Description

technical field [0001] The invention relates to a composite thermal management system for a data center cabinet in which a server is equipped with a loop heat pipe heat exchanger and a cross-flow fan, and belongs to the field of high-efficiency heat dissipation in the data center. Background technique [0002] The data center has now become an important part of the national economic development and the main pillar to promote the informatization and digitization of the national science and technology industry. With the vigorous development of my country's communication industry, the electronic computer itself and the degree of integration are getting higher and higher, and the heat dissipation of the data center cabinet is increasing, which is prone to local overheating, which brings great safety hazards and endangers the safety of the data center; In addition, the existing air conditioners are integral air conditioners in the computer room. The problem of temperature accumula...

Patent CN201521067250 proposes a data center cabinet that can precisely adjust the airflow organization. This patent sets up a vertically adjustable interception guide plate under the raised floor, but it can only improve the uneven heat dissipation of the cabinets at different positions, and cannot go deep into the inside of the cabinet. The local hot spot of the server is improved; the patent CN108571792A proposes a natural cooling system and its control method for a data computer room. The patent is to set a cold channel inside the data computer room, and use an air heat exchanger for parallel countercurrent heat exchange, although it can reduce energy consumption , but the traditional overall air conditioning method is still adopted, which also cannot efficiently solve the heat dissipation problem in the cabinet, and the degree of energy consumption reduction is relatively limited
