Liquid cooling temperature control system allowing wide temperature range natural cooling

Abstract

The invention discloses a liquid cooling temperature control system allowing wide temperature range natural cooling, comprising an internal circulation system for cooling a heating device, first and second heat exchangers connected parallelly to the internal circulation system, and first and second external circulation systems used to cooling a liquid coolant in the internal circulation system and capable of running independently; the first external circulation system comprises a cooling column, and the second external circulation system comprises a dry cooler; the first and second external circulation systems are run respectively at high or low ambient temperature. The application environment temperature range of the liquid cooling temperature control system is widened, and the liquid cooling temperature control system can make full use of natural cold source to cool heating equipment at a different ambient temperature; in addition, by running the liquid cooling temperature control system at low ambient temperature, the resources, such as water and electricity, are saved, the anti-freezing problem of the cooling column is solved, and operation and maintenance costs of the liquid cooling temperature control system are decreased accordingly.

Description

technical field [0001] The invention relates to the field of equipment heat dissipation, in particular to a liquid cooling temperature control system capable of realizing natural cooling in a wide temperature range. Background technique [0002] Liquid cooling technology includes direct cooling and indirect cooling, and direct liquid cooling has thermal shock wave phenomenon caused by thermal lag and inconvenient system maintenance, so it is gradually replaced by indirect liquid cooling. The indirect liquid cooling method means that the liquid coolant does not directly contact the heating equipment, but dissipates the heat through the liquid-cooled temperature control system, that is, the heat is exported from the inside through the liquid-cooled heat pipe radiator, and then transferred to the liquid through the cold plate. Coolant, the liquid coolant takes away heat from the heat source through the internal circulation system, and then dissipates the heat through the extern...

AI Technical Summary

Problems solved by technology

[0003] At present, the external circulation heat dissipation system of the liquid-cooled temperature control system usually only uses cooling towers for natural cooling, which is not suitable for low-temperature cold regions or seasons, because cooling towers usually require anti-freezing measures such as electric heating in low-temperature environments, which greatly increases system power consumption. , In addition, the continuous operation of cooling towers in winter and summer will also lead to an increase in the frequency of cooling tower inspection and maintenance, which increases the maintenance cost of system operation
