Abstract

The invention provides a technical scheme of a phase change cold accumulating device. According to the scheme, the phase change cold accumulating device comprises a heat taking cold plate, a heat releasing cold plate, a framework material, a phase change material and a heat isolation material which are arranged in a package shell. The framework material is arranged between the heat taking cold plate and the heat releasing cold plate. The framework material, the heat releasing cold plate and the heat taking cold plate are arranged in a laminated stacking and staggered mode. The framework material is filled with the phase change material. The heat isolation material is arranged on the inner wall of the package shell. A heat taking loop is arranged in the heat taking cold plate. A heat releasing loop is arranged in the heat releasing cold plate. A heat taking secondary refrigerant is arranged in the heat taking loop. A heat releasing secondary refrigerant is arranged in the heat releasing loop. An exhaust hole and a phase change material adding port are formed in the top of the package shell. According to the scheme, the heat releasing loop, the heat taking loop and the phase change material are utilized for carrying out heat exchange, additional energy is not needed, and the whole device is small in size and low in energy consumption.

Description

technical field [0001] The invention relates to the field of heat exchange management, in particular to a phase change cold storage device. Background technique [0002] The research focus of thermal management technology is to solve the transfer process of heat from the heat source to the cooling medium under high heat flux in the "heat extraction loop", but the "heat release loop" and how to reduce the volume, weight and power consumption of the thermal management system have not yet been solved. draw enough attention. With the development of solid-state lasers in the direction of long-term and higher power, if the traditional micro-channel real-time water cooling method is still used, the volume, weight and power consumption of the thermal management system will be extremely large, which greatly limits high-power solid-state lasers. field of application. [0003] Phase change cold storage is a method of storing cold energy through phase change of phase change materials,...
