Abstract

The invention discloses a multigrid phase-change energy storage device, a pump-driven heat exchange system and a heat exchange method. The multigrid phase-change energy storage device is composed of ashell body, a heat transfer pipeline, a foam metal and a phase-change material, the heat transfer pipeline in the multigrid phase-change energy storage device comprises an inlet pipe section, an outlet pipe section and heat exchange pipe sections between the inlet pipe section and the outlet pipe section; and the heat exchange pipe sections are symmetrically distributed in the shell body, a horizontal pipe section is of a multigrid structure, the pipe length and pipe diameter of different stages of heat exchange pipe sections are formed according to a bionics principle, and thus an optimal heat flow channel is constructed from the center to the surrounding. The multigrid phase-change energy storage device is used as a cooling cold end of a pump-driven circuit, and the heat management requirements of high power consumption and intermittent working equipment can be met under the extreme heat dissipation environment.

Description

technical field [0001] The invention relates to the technical field of phase change energy storage, in particular to a phase change energy storage device with multi-grid structure features and a pump drive heat exchange system designed to cope with objects with high heat dissipation requirements in a short period of time. Background technique [0002] National defense and military strength account for a large proportion in the comparison of the comprehensive national strength of various countries. The development of military science and technology in various countries is changing with each passing day. In order to meet the needs of modern military strategies, high-energy equipment such as laser weapons has been developed rapidly. Not only the energy consumption has increased sharply, but also due to the further increase in the degree of equipment integration, the heat dissipation index in the limited space has increased sharply, and the heat dissipation conditions are also li...

AI Technical Summary

Problems solved by technology

Not only the energy consumption has increased sharply, but also due to the further increase in the degree of equipment integration, the heat dissipation index in the limited space has increased sharply, and the heat dissipation conditions are also limited.

For some equipment that works intermittently, such as laser weapons, the instantaneous working power can reach the megawatt level, but each time the working time is very short, the heat dissipation load in this place changes drastically, and ordinary air cooling conditions are difficult to meet. Liquid cooling will increase the volume of the cooling system, and it is difficult to recycle and other disadvantages. Therefore, the use of phase change energy storage can well coordinate the inconsistency of heat in time
