Equipment cabinet liquid cooling system

Abstract

The invention relates to the technical field of equipment cabinet heat dissipation and discloses an equipment cabinet liquid cooling system, which comprises a plurality of equipment cabinets, whereinheat dissipation cabinets is arranged on the back sides of the equipment cabinets; a cooling coil is arranged in a cooling chamber; the cooling chamber is filled with a heat conductive medium; the lower end of the cooling coil on each equipment cabinet is connected to a main water inlet pipe through a branch water inlet pipe; the upper end of the cooling coil on each equipment cabinet is connectedto a main water outlet pipe through a branch water outlet pipe; and a water pump is disposed on the main water inlet pipe. The equipment cabinet liquid cooling system further comprises a double watersource heat pump which includes a condenser and an evaporator, wherein a return pipe is connected between the water outlet end of the main water outlet pipe and the water inlet end of the main waterinlet pipe, passes through the evaporator, and is provided with a valve A; a water tank is arranged between the return pipe and the main water inlet pipe; a valve B is arranged between the water tankand the main water inlet pipe; a valve C is arranged on the water inlet end of a hot water pipe; valves D are arranged on the branch water inlet pipes of respective equipment cabinets; and a valve E is arranged at the water inlet end of a cold water pipe. The equipment cabinet liquid cooling system has high heat dissipation efficiency and good dustproof performance.

Description

technical field [0001] The invention relates to the technical field of cabinet cooling, in particular to a cabinet liquid cooling system. Background technique [0002] At present, in some large computer rooms, there are a large number of cabinets, and various data processors, controllers and other electronic equipment are installed inside the cabinets, which generate a lot of heat, and there are many cabinets in the computer room, and various electronic devices in the cabinets are in operation. A large amount of heat will be generated. If the heat cannot be removed in time, the service life, operating efficiency and stability of the electronic equipment in the cabinet will be reduced, or even malfunction. At present, the computer room is usually air-conditioned and refrigerated throughout the year, and fans are used in the cabinet to exchange heat with the cold air in the computer room, so as to maintain good heat dissipation inside the cabinet. However, the inside of the c...

Problems solved by technology

However, the inside of the cabinet is air-cooled to dissipate heat, and the heat dissipation efficiency is low. The space in the computer room is large, and the air conditioner is used for cooling. On the one hand, the energy consumption is very large. Keep the computer room at low temperature and compensate for the heat exchange between the computer room and the outside. In the actual process, the temperature inside the cabinet is much higher than that in the computer room, which is not conducive to the good operation of the electronic equipment inside the cabinet. Moreover, the air conditioner in the computer room consumes a lot of energy, but it does not give the cabinet Bring good heat dissipation effect, resulting in great waste of energy consumption

Moreover, many electronic devices inside the cabinet need to be dust-proof, and the air flow between the cabinet and the computer room can easily bring the dust in the computer room into the cabinet.
