Abstract

The invention discloses an evaporation cooling technology-based liquid cooling system. The evaporation cooling technology-based liquid cooling system comprises a liquid-cooling server unit, a plate-type heat exchanger and an evaporation cooling cold water machine set which are arranged in a machine room, wherein two sides of the liquid-cooling server unit are respectively connected with one end ofa secondary water system water supply pipe and one end of a secondary water system water return pipe, the other ends of the secondary water system water supply pipe and the secondary water system water return pipe are connected with the plate-type heat exchanger, and a secondary water system water pump is arranged on the secondary water system water supply pipe. The liquid cooling system employsan indirect cold plate-type liquid-cooling server, an indirect cold plate is attached onto a server chip, heat sent out from the chip is taken away by flowing of water in the indirect cold plate, thecooling efficiency is high, and the liquid-cooling server unit is easily accepted by market; and the evaporation cooling cold water machine set employs an indirect-direct evaporation cooling mode, cold water lower than environmental wet bulb temperature can be made, and the evaporation cooling cold water machine is widely applicable to a data center with a liquid-cooling server.

Description

technical field [0001] The invention belongs to the technical field of air conditioning and refrigeration, and in particular relates to a liquid cooling system based on evaporative cooling technology. Background technique [0002] In recent years, the development of domestic informatization has become more and more mature, and the data center industry has risen rapidly. With the development of supercomputers, the integration level and calculation speed of chips have been continuously improved, the energy consumption has also been increased, and the problem of heat dissipation has become increasingly prominent. Since the current main cooling method is air cooling, the traditional air cooling heat dissipation method is a direct heat transfer method, and the convective heat transfer method relying on single-phase fluid and the forced air cooling method can only be used for heat flux density not greater than 10W / cm 2 For electronic devices with a heat flux greater than 10W / cm ...
