Waste heat recovery system of liquid cooling data center

Abstract

The invention discloses a waste heat recovery system of a liquid cooling data center. The waste heat recovery system comprises a first heat exchanger, a heat dissipation system, a solar heat collection and heat storage system and a heat energy utilization system, wherein each system is a circulation loop internally provided with a working medium flow, the first heat exchanger is a part of the heatdissipation system, the heat dissipation system and the solar heat collection and storage system are connected with the heat energy utilization system through a heat exchange pipeline and the solar heat collection and storage system to provide heat energy, and the waste heat of the solar heat collection and heat storage system is used for civil heating. The solar heat collection and heat storagesystem is used for upgrading a low-temperature waste heat source, energy storage is carried out, the input energy fluctuation in the daytime and at night is balanced, the heat source is utilized for heat energy utilization, the waste heat is used for providing hot water and heating for a building, redundant low-grade heat is discharged into the environment through a cooling tower, and the waste heat recovery efficiency of the liquid cooling data center is improved, the energy consumption of the data center is reduced, the energy utilization efficiency is improved, the energy consumption is reduced, and meanwhile, the operation cost of the data center is reduced.

Description

technical field [0001] The invention relates to a waste heat recovery system of a liquid-cooled data center. Background technique [0002] In recent years, with the rapid increase of data center energy consumption, the country has attached great importance to it, and then put forward the concept of green data center. Compared with air-cooled data centers, liquid-cooled data centers can save energy by more than 30%. Therefore, low-energy liquid-cooled data centers have attracted more attention. However, this part of the energy saving of the liquid-cooled data center is saved from cooling the cooling equipment of the data center, and the energy consumption of the server is inevitable. If the heat energy consumed by the server can be reused, the efficiency of the data center will be further improved. energy efficiency. [0003] At present, the recovery of waste heat in liquid-cooled data centers is mainly to use the heat energy through heat pumps or directly for winter buildi...

Problems solved by technology

[0005] ⑴Affected by the seasons, the heat demand is high in spring and winter, and the efficiency of waste heat recovery is high, but the heat demand in summer and autumn is small, the grade of waste heat is low, and the efficiency of cooling is low

[0006] (2) The investment in recovery equipment is high, and the economic benefits are not obvious, resulting in the long-term waste heat recovery efficiency not reaching the practical level, and the entire system has high investment and low efficiency, making it difficult to use in practice
