Embodiment 1

[0021] see figure 1 The energy-saving uniform temperature refrigerator includes a freezer 6, a freezer 7, a compressor 8, a condenser 9, an evaporator 10, and a capillary 11. The walls of the freezer 6 and the freezer 7 are filled with polyurethane foam. The foam material 1; the freezing chamber 6 is located in the upper part, and the refrigerating chamber 7 is located in the lower part of the freezing chamber 6. Annular heat pipe mechanisms are respectively installed in the top, back and two side walls of the freezer except the freezer door and the partition wall between the freezer and the freezer.

[0022] see figure 1 and figure 2 , the structure of the annular heat pipe mechanism in the top, back and two side walls of the freezing chamber 6 is as follows:

[0023] The annular heat pipe mechanism located at the back of the freezing chamber 6 is composed of a heat conducting plate 5 and an annular heat pipe. In the refrigerator compartment 7.

[0024] The annular heat...

Embodiment 2

[0028] The distance between the heat conducting plate 5 and the inner side wall of the freezing chamber 6 is one-eighth of the wall thickness of the freezing chamber 6, and the other structures are the same as in Embodiment 1.

Embodiment 3

[0030] The distance between the heat conducting plate 5 and the inner side wall of the freezing chamber 6 is one-third of the wall thickness of the freezing chamber 6, and the other structures are the same as in Embodiment 1.

[0031] The working principle of the present invention is described as follows:

[0032] see figure 1 , when the temperature of the refrigerating chamber 7 is high, the temperature control valve 4 is opened, and the working medium in the multiple annular heat pipe pipes is heated and evaporated into a gaseous state in the evaporation section 3 of the annular heat pipe, and the gas rises into the condensation section of the annular heat pipe to exchange heat with the heat conducting plate 5 Cooled into a liquid state, the condensed liquid working medium then relies on capillary force and gravity to return to the evaporation section 3 of the annular heat pipe to complete the cycle, and at the same time the working medium transfers the cold energy of the fr...

Abstract

The invention relates to an energy-saving uniform-temperature refrigerator. The energy-saving uniform-temperature refrigerator comprises a freezing chamber, a refrigerating chamber, a compressor, an evaporator, a condenser and a capillary tube, wherein the chamber wall of the refrigerating chamber and the chamber wall of the freezing chamber are respectively filled with a polyurethane foaming material; the freezing chamber is positioned on the upper part, and the refrigerating chamber is positioned at the lower part of the freezing chamber; an annular heat pipe mechanism is respectively arranged in the top, the back part and two side walls of the freezing chamber except a partition wall between a freezing chamber door and the refrigerating chamber; each annular heat pipe mechanism consists of a heat conduction plate and an annular heat pipe; a condensing section of each annular heat pipe is embedded into each heat conduction plate; the heat conduction plates and the condensing sections of the annular heat pipes are wrapped by the polyurethane foaming materials; evaporating sections of the annular heat pipes are positioned in the refrigerating chamber to substitute an evaporator of a refrigerating chamber of an existing refrigerator and transfer a part of cold in the freezing chamber into the refrigerating chamber for refrigerating of the refrigerating chamber. According to the energy-saving uniform-temperature refrigerator disclosed by the invention, the temperature fluctuation amplitude in the refrigerating chamber of the refrigerator can be effectively reduced by frequent start-stop of a heat exchange process of the annular heat pipes, and meanwhile, the loss of cold conducted from the freezing chamber of the refrigerator to an indoor environment is reduced.

Description

technical field [0001] The invention belongs to the technical field of home appliance refrigerators, in particular to an energy-saving refrigerator with the function of precise temperature control of a refrigerator. Background technique [0002] In terms of the application of refrigerator energy-saving technology, due to the large difference between the temperature in the refrigerator freezer and the room temperature, reducing the loss of refrigerator cooling capacity by strengthening the insulation effect of the refrigerator insulation layer has always been one of the key research directions. By increasing the thickness of the polyurethane foam layer in the refrigerator-freezer or adding a vacuum insulation board in the polyurethane foam layer, the heat insulation effect of the refrigerator insulation layer can be significantly strengthened, and the energy consumption of the refrigerator can be reduced, but too thick foam layer will Seriously affect the appearance of the re...
