Machine room heat pipe cold accumulation coupled emergency refrigerating system and method

Abstract

The invention discloses a machine room heat pipe cold accumulation coupled emergency refrigerating system and method. The system comprises a condensation end cabinet for discharging heat in a machine room and an evaporation end cabinet for absorbing the heat in the machine room. The condensation end cabinet comprises a compressor, a condenser, a capillary tube, a cold accumulation device, a first solenoid valve and a circulation cold accumulation loop composed of pipes for connecting the compressor, the condenser, the capillary tube, the cold accumulation device and the first solenoid valve. The evaporation end cabinet comprises a heat exchanger and a second solenoid valve. The evaporation end cabinet is connected with the cold accumulation device of the condensation end cabinet through a separated heat pipe to form a working medium circulation cold release loop. When the electric supply is cut off, by means of the machine room heat pipe cold accumulation coupled emergency refrigerating system and method, the cold energy provided by the cold accumulation device is adopted to maintain the refrigerating system to work normally, and normal operation of a server is guaranteed. The whole system is simple in structure, environmentally friendly, reliable and capable of saving energy.

Description

technical field [0001] The invention relates to an emergency refrigeration system and method coupled with heat pipe cold storage in a machine room. Background technique [0002] With the rapid development of communication technology, the calorific value of electronic equipment per unit volume has risen sharply, and the cooling capacity in the data center is increasing. Once the power supply fails, although the server can continue to run by relying on the UPS system, due to the shutdown of the cooling equipment running, causing the temperature in the computer room to rise rapidly, which will still cause the server to overheat and stop running. [0003] According to Intel's experimental analysis, in a computer room with a single cabinet of 1.2KW, if the refrigeration system is stopped for 10 minutes, the temperature will rise by 10.5°C. For a 9KW computer room with a single cabinet, once the cooling system stops, it only takes 18 seconds for the temperature to rise from 22°C ...

Problems solved by technology

The scheme is too simple, and the effect of emergency cooling is limited

[0007] (3) The patent with the publication number CN203147950U discloses a cold storage type emergency cooling device (application number: 201320086909.4). This patent uses a special cylinder and a water distributor to realize emergency refrigeration through the circulation of chilled water, which occupies a large volume. Not suitable for computer room layout, and the cooling effect is limited

In this patent, the two circuits are partially overlapped and partially connected in parallel. This patent mainly uses the outdoor natural cold source for cold storage, which cannot quickly provide the corresponding cooling capacity when the cooling system of the machine room stops running, and the two cold storage cycles are long, which cannot be used in cold storage. The case of multiple cooling in a short period of time
