Heat pipe type air conditioner system for data center and heat dissipating method of heat pipe type air conditioner system

Abstract

The invention discloses a heat pipe type air conditioner system for a data center. An inner circulation subsystem and an outer circulation subsystem are formed by an air conditioner, a cabinet ventilation unit and a heat pipe unit. A shell is partitioned into two sealed spaces through a partition plate, and the heat pipe unit is arranged in the shell in the mode that the heat end and the cold end of the heat pipe unit are located in the two sealed spaces of the shell respectively. An air outlet of the air conditioner is communicated with an air inlet of the cabinet ventilation unit through a pipeline, an air outlet of the cabinet ventilation unit is communicated with an air inlet in one side of the sealed space with the heat end of the heat pipe unit through a pipeline, an air outlet located in the side opposite to the air inlet in one side of the sealed space with the heat end of the heat pipe unit is connected with an air inlet of the air conditioner through a pipeline, and thus the inner circulation subsystem is formed. The air inlet is formed in one side of the sealed space with the cold end of the heat pipe unit, an air outlet is formed in the opposite side, and thus the outer circulation subsystem is formed through action of a draught fan of the sealed space with the cold end of the heat pipe unit and the external environment. The heat pipe type air conditioner system can effectively prevent clod air flow and hot air flow from mixing with each other in a machine room, and the overall heat dissipating efficiency of the machine room is improved.

Description

technical field [0001] The invention belongs to the technical field of machine room heat dissipation and heat pipe heat exchange, and relates to a heat pipe air-conditioning system used in a data center (or machine room) and a high-efficiency heat dissipation method. Background technique [0002] The data center (also known as the computer room) has become an important part of the development of the national economy and the main pillar to promote the informatization and digitization of the national science and technology industry. With the development of the scale and integration of data centers, the power density of IT equipment in servers is increasing day by day, and the heat density is increasing rapidly. The heat dissipation and energy consumption problems of data centers are getting more and more attention. Taking 100 cabinets filled with rack servers as an example, the total power consumption can reach 50 kilowatts, and the heat dissipation and cooling system also nee...

Problems solved by technology

However, there are several deficiencies in this patent disclosure: 1) it does not involve avoiding the mixing of hot and cold air in the computer room, so it cannot efficiently solve the problem of heat dissipation in the computer room, and the energy consumption of the computer room is not greatly reduced; 2) the system adopts The most popular is the vertical heat pipe heat exchanger, the heat pipe is vertically installed in the shell, and the condensation section of the heat pipe is located directly above the heating section, so the height of the whole system is relatively high, which has a high impact on the wall opening and load bearing. Requirements, wall hanging installation is more restrictive, more suitable for vertical installation on the ground

However, this patent has the following disadvantages: 1) the combination of the heat pipe and the air conditioner requires redesigning or disassembly of the air conditioner, which is inconvenient for system implementation and maintenance; 2) the patent does not disclose the details of the heat pipe it uses, only giving A schematic diagram of the position of the heat pipe in the air-conditioning device is shown, and the operational feasibility needs to be improved

The document "Experimental Research on the Performance of Heat Pipe Air Conditioning in Computer Room" placed the heat pipe heat exchanger on the ground outside the computer room, and also did not involve measures to avoid the mixing of hot and cold air in the computer room. The document "Application Research of Heat Pipe Air Conditioning System in Information Computer Room" The separated heat pipe heat exchanger is used, the advantage is that it can be arranged at a long distance, and the disadvantage is that its heat transfer efficiency is lower than that of the compact heat pipe heat exchanger. In the heat pipe heat exchanger, the heat pipe is a gravity water heat pipe, and the working medium of the heat pipe is water. Since the phase transition temperature of water is relatively high, the heat transfer capacity of this heat pipe is limited.
