An electronic device liquid cooling system based on phase change cold accumulation and double-flow channel isolation and a control method thereof

Abstract

This invention relates to the field of heat dissipation technology for electronic devices, and particularly to a liquid cooling system and control method for electronic devices based on phase change cold storage and dual-channel isolation. The system includes a cold storage module, a compression refrigeration circuit, a direct evaporation cooling circuit, and a control system. The cold storage module encapsulates a phase change cold storage material and integrates physically isolated first and second refrigerant channels. The compression refrigeration circuit is connected sequentially to a compressor, a condenser, and the first refrigerant channel via piping, utilizing the refrigerant to directly exchange heat with the phase change material to achieve cold storage. The direct evaporation cooling circuit is connected sequentially to a refrigerant pump module, an electronic device cold plate, and the second refrigerant channel via piping, utilizing the cold energy stored in the phase change material to directly condense the refrigerant vapor from the cold plate. This invention achieves direct and efficient heat exchange in the cold storage and release processes, possessing advantages such as high heat dissipation efficiency, significant energy saving, and a compact structure.
