Problems solved by technology

[0005] The present invention overcomes the deficiencies of the prior art, and provides a heat storage type condenser using a shape-fixed phase change material. By using the shape-fixed phase change material to store the condensation heat of the condenser, the continuous heat release of the refrigerator condenser is realized, and the refrigerator temperature is improved. The overall heat dissipation effect of the box-wall condenser; and the shape-fixed phase-change material always maintains the same shape during the phase change process, which effectively solves the difficult problem of packaging; at the same time, the shape-fixed phase-change material is non-toxic and non-corrosive; thus making the condenser The production difficulty is reduced, safe and reliable, and the production cost is low

Embodiment 1

[0025] The thermal storage material in this embodiment is a fixed phase change material, combined with figure 1 illustrate: figure 1 Among them, 1 is a fixed phase change material, 2 is a condensation pipe, 3 is a refrigerator insulation material, and 4 is a refrigerator box wall. The shape-setting phase change material has properties such as high thermal conductivity, adjustable phase change temperature, large latent heat of phase change, solid state of the material before and after the phase change, no leakage, and no need for packaging.

[0026] In this embodiment, the structure of the heat exchanger: the condensation pipe 2 is in direct contact with the refrigerator wall 4, the shape-setting phase change material 1 completely surrounds the condensation pipe 2, and the shape-setting phase change material 1 fixes the condensation pipe 2 on the refrigerator insulation material 3 Phase change between 4 and refrigerator.

[0027] In this embodiment, the thermal conductivity o...

Embodiment 2

[0029] The thermal storage material in this embodiment is a fixed phase change material, combined with figure 2 illustrate: figure 1 Among them, 1 is a fixed phase change material, 2 is a condensation pipe, 3 is a refrigerator insulation material, and 4 is a refrigerator box wall.

[0030] The difference between this embodiment and Embodiment 1 is that in this embodiment the condensation pipe 2 does not directly contact the refrigerator wall 4 , but in Embodiment 1 the condensation pipe 2 directly contacts the refrigerator wall.

Embodiment 3

[0032] The thermal storage material in this embodiment is a fixed phase change material, combined with image 3 illustrate: figure 1 Among them, 1 is a fixed phase change material, 2 is a condensation pipe, 3 is a refrigerator insulation material, and 4 is a refrigerator box wall.

[0033] The structure of the heat exchanger in this embodiment: the condensation pipe 2 is in direct contact with the refrigerator wall 4, and the shape-setting phase change material 1 is not completely fast, but the condensation pipe 2 is surrounded by the shape-setting phase change material 1, and It is fixed between the refrigerator insulation material 3 and the refrigerator case wall.

[0034] This embodiment mainly considers saving the shape-fixed phase-change material, and only uses the shape-set phase-change material where it is used.

Abstract

The invention discloses a heat-accumulating condenser using a shape-stabilized phase change material. The condenser comprises the shape-stabilized phase change material, a condensation pipe, an external wall plate and a heat-insulating material. The condenser is characterized in that: the condenser is completely or partially surrounded in the shape-stabilized phase change material to form a heat-accumulating condensing component; the heat-accumulating condensing component tightly clings to the external wall plate; and the inner sides of the external wall plate and the heat-accumulating condensing component are made of the heat-insulating material. The shape-stabilized phase change material is a paraffin composite material which is prepared by compositing a paraffin and a high molecular material and a heat-conducting reinforcing agent can be also added into the phase change material. In the invention, the shape-stabilized phase change material allows the condenser to continuously release heat to the outside by accumulating heat for the condenser, so that the radiation effect of the condenser is improved. The shape-stabilized phase change material is always kept in a solid state in the heat accumulating process, does not need to be packaged and has no toxicity or corrosiveness, so that the production cost of the condenser is reduced. The heat-accumulating condenser is applied to the refrigeration equipment, such as refrigerators, low-temperature ovens, refrigeration cabinets, drink refrigerators, ice cream machines, small discontinuous refrigerating machines and the like.

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 condensing tube and the tank wall are theoretically in line contact, so the heat conduction effect between the condensing tube and the tank wall is poor. Moreover, since the heat dissipation between the refrigerator condenser and the environment is ma...
