Heat accumulation type condenser using shape-stabilized phase-change material

Abstract

The invention relates to a heat accumulation type condenser using shape-stabilized phase-change material, comprising the shape-stabilized phase-change material, a condenser pipe, a refrigerator wall and refrigerator heat insulation material. The heat accumulation type condenser is characterized in that the condenser pipe is completely or partly surrounded by the shape-stabilized phase-change material, and is fixed between the refrigerator heat insulation material and the refrigerator wall by the shape-stabilized phase-change material. The phase-change material in the shape-stabilized phase-change material is paraffin wax substances, support material is high-density polyethylene, and expanded graphite can be taken as heat conduction reinforcing agent. In the invention, the shape-stabilized phase-change material can be used for reinforcing the heat transmission between the condenser pipe and the refrigerator wall, and is also used for accumulating heat to lead the condenser pipe to continuously emit heat outside, so that the condensation efficiency of the condenser can be improved; furthermore, in the process of heat accumulation, the shape-stabilized phase-change material is maintained to be a solid state and does not flow, so that the leakage problem is not caused, and the condenser is not needed to be encapsulated so as to have low production difficulty. The heat accumulation type condenser is applicable to refrigeration equipment such as a refrigerator, a low temperature box, a freezer, a cold drink machine, an ice cream machine, an intermittent minitype refrigerating machine, etc.

Description

technical field [0001] The invention relates to a condenser, in particular to a heat-storage condenser utilizing a fixed-shape phase-change material, which belongs to the field of refrigeration technology and is suitable for refrigerators, refrigerators, low-temperature boxes, cold drink machines, ice cream machines and discontinuously working machines. Refrigeration equipment such as small refrigerators. technical background [0002] At present, the box-wall condenser in the refrigerator condenser has the advantages of compact structure, does not occupy external space, is not easy to damage, is easy to clean, and is flat and beautiful, and has gradually become the mainstream condenser. However, in the tube wall condenser, the contact between the condenser tube and the box wall can only be a line in theory, so the heat conduction effect between the condenser tube and the box wall is poor. Moreover, since the heat dissipation between the refrigerator condenser and the enviro...
