Active solid-liquid phase change material heat exchange circulation system

Abstract

The invention provides an active solid-liquid phase change material heat exchange circulation system. Through the structural arrangement design of a spiral pipe and a rotary crushing tool bit in a heat release end box body, when the rotary crushing tool bit operates, a liquid solid-liquid phase change material in the heat release end box body can be driven to flow, circular turbulence is formed, and a solid solid-liquid phase change material formed through heat exchange cooling in the heat release end box body can be driven by the circular turbulence so as to be cut and crushed by the rotary crushing tool bit. The problem of conveying blockage caused by the solid solid-liquid phase change material is solved. Meanwhile, through the circular turbulence, the solid solid-liquid phase change material formed through heat exchange cooling is not prone to being condensed or wrapping the pipe wall of the spiral pipe, and the heat exchange blockage problem is solved. By means of scouring of the turbulence, the heat exchange contact area between the solid-liquid phase change materials and the spiral pipe is further increased, the heat exchange efficiency between the solid-liquid phase change materials and a cooling source can be effectively improved, and effective operation of heat exchange circulation of the solid-liquid phase change materials is better guaranteed.

Description

technical field [0001] The invention relates to the technical field of heat storage application of phase change materials, in particular to an active solid-liquid phase change material heat exchange cycle system. Background technique [0002] Phase change material (PCM, Phase Change Material) refers to a substance that changes shape with temperature and can provide latent heat. Phase change materials can be used as heat accumulators, and their heat storage properties are of great significance in the fields of energy saving and temperature control. Compared with liquid-gas phase change and solid-gas phase change heat accumulators, solid-liquid phase change heat accumulators are widely used in waste heat recovery, solar energy storage, and heating and air conditioning due to their advantages of high volume heat storage density and small heat storage temperature difference. system. The solid-liquid phase change heat storage technology uses the energy absorption and release of...

Problems solved by technology

However, in the solid-liquid phase change material heat exchange cycle system, there is always a problem that is difficult to solve, that is, the fluidity of the solid phase change material after heat release in the exothermic end box increases, and it is transported back to the endothermic end box. The difficulty of the body, only relying solely on the hydraulic pressure of the liquid pump to provide circulation power is prone to blockage, resulting in slow or blocked circulation of the solid-liquid phase change material, and the solid phase change material formed by solidification after cooling and heat release in the exothermic end box It is easy to condense or wrap on the heat sink or coil of the cold source, resulting in the obstruction of the contact between the heat sink or coil of the cold source and the liquid solid-liquid phase change material. These problems will reduce the contact between the liquid solid-liquid phase change material and the heat sink. The heat transfer efficiency between
