Abstract

The invention provides a digital server heat energy efficient recovery system and a control method thereof. The system comprises a heating device, a heat storage water tank and at least one heat energy exchange cabinet, and a server is arranged in the heat energy exchange cabinet; the heat storage water tank is connected with the heating device and used for exchanging heat with the heating device; the heat energy exchange cabinet is provided with a water inlet pipe and a water outlet pipe, and the water outlet pipe is connected with the heat storage water tank, and the water inlet pipe is connected with the heating device; and the system further comprises a cooling water tower, and the cooling water tower is connected with the heating device and the water inlet pipe and used for conducting secondary cooling on heating return water and transferring the heating return water subjected to secondary cooling to the heat energy exchange cabinet. According to the digital server heat energy efficient recovery system provided by the invention, the heat energy generated in the operation process of the server is transmitted into the heating device, and the heat energy is recycled by establishing a heat energy circulation system. The PUE value of the system is close to 1, the cooling effect of the server is guaranteed, meanwhile, cyclic utilization of energy is achieved, and the operation cost is reduced.

Description

technical field [0001] The invention relates to the field of heat energy recovery, in particular to a digital server heat energy efficient recovery system and a control method thereof. Background technique [0002] PUE (Power Usage Effectiveness) is an indicator for evaluating the energy efficiency of a data center, and it is the ratio of all energy consumed by the data center to the energy consumed by IT loads. PUE = total energy consumption of the data center / energy consumption of IT equipment, where the total energy consumption of the data center includes energy consumption of IT equipment and energy consumption of cooling, power distribution and other systems. PUE has become an internationally accepted measure of data center power usage efficiency. The PUE value refers to the ratio of all the energy consumed by the data center to the energy consumed by the IT load. The closer the PUE value is to 1, the higher the greenness of a data center. [0003] With the high-dens...

AI Technical Summary

Problems solved by technology

[0004] However, there are often a lot of disadvantages in the related solutions about server cooling in the prior art.

First of all, the existing IDC computer room occupies a large area, coupled with various energy consumption, resulting in extremely high operating costs, and the server is often accompanied by noise pollution during operation

Secondly, the PUE value of existing server equipment is generally high, far greater than 1, which cannot meet the needs of economic benefits

Furthermore, most of the heat energy generated by the operation of servers in the prior art is discharged into the atmosphere directly or through air conditioners and other equipment, which not only cannot be recycled, but also requires huge costs for heat dissipation treatment, which is not conducive to resource conservation and environmental protection
