Phase change energy storage tank system suitable for data center and data center platform

Abstract

The invention relates to the technical field of phase change energy storage, and provides a phase change energy storage tank system suitable for a data center. The outer surface of a heat storage tank(300) is provided with a microchannel heat exchanger (400), and waste heat of the data center can be transferred to a phase change material (500) to be stored; the phase change material (500) in theheat storage tank (300) and a working medium passing through a spiral coil pipe (200) are subjected to heat exchange, so that the heat is released, and the heat serves as a good-quality heat source for heating, hot water and the like; and the heat is flexible and convenient to store and release and is not limited by time. According to the system, waste of the waste heat of the data center is reduced, heat recycling is realized, automation can be realized, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of phase change energy storage, in particular to a phase change energy storage system for data center waste heat recovery. Background technique [0002] A data center is a building site that gathers a large number of computing equipment, storage equipment, network equipment and other equipment. It is an infrastructure and service platform for centralized processing, storage, transmission, exchange, and management of data information. In recent years, data centers have gradually developed towards large-scale and high-density development, and the machinery and equipment in the computer room are operating 24 hours a day, which also makes their heat generation continue to increase. At present, the full-load heat dissipation density of high-end single-chip CPU is as high as 75W / cm2, the power of a single 1U server can reach 400W, and the floor area of ​​a standard rack is only 0.48m2, but its power is as high as ...

AI Technical Summary

Problems solved by technology

However, for the application scenario of high heat dissipation density in the data center, it is required that the phase change energy storage heat exchanger has good heat transfer performance and can store heat in the phase change material in time, which requires various Technical means to solve the problem of low heat transfer efficiency of phase change energy storage heat exchanger

For example, in the data center heat recovery system disclosed in the patent document CN208779540U, different modes can be switched in the utilization of heat recovery. Energy recovery is limited by time, and energy storage cannot be realized. The recovery valve can only be activated when the user needs it.
