Since the characteristics of the heat pipe are readily known to those skilled in the art, they will not be described in detail herein.

In some embodiments, the refrigerant outlet of the condensation side heat exchanger 21 is connected to the refrigerant inlet of the evaporation side heat exchanger 22 through an inlet pipe 25, so that the liquid refrigerant flowing out of the condensation side heat exchanger 21 flows to the evaporation side heat exchanger 22 through the inlet pipe 25. The refrigerant outlet of the evaporation side heat exchanger 22 is connected to the refrigerant inlet of the condensation side heat exchanger 21 through a gas return pipe 26, so that the gaseous refrigerant flowing out of the evaporation side heat exchanger 22 returns to the condensation side heat exchanger 21 through the gas return pipe 26. It will be understood by those skilled in the art that the inlet pipe 25 and the return pipe 26 may be connected pipe sections of the heat pipe which do not have a heat exchange function.

Further, a subcooler 27 is provided on the intake pipe 25. Specifically, the subcooler 27 may be fixedly connected with the tube body of the air inlet tube 25 by welding, and the two are in fluid communication with each other.

In some embodiments, the heat pipe refrigeration system further comprises an accumulator 23 disposed on the air intake 25 to regulate the amount of refrigerant circulating in the heat pipe refrigeration system based on the external ambient temperature. The liquid storage device 23 can store a certain amount of refrigerant, so that the amount of the refrigerant circulating in the heat pipe refrigeration system can be conveniently adjusted according to the external environment temperature, and the refrigerator 1 can obtain a good refrigeration effect under different external environment temperatures. Specifically, when the outside ambient temperature decreases, the amount of refrigerant participating in the circulation of the heat pipe refrigeration system decreases, and the accumulator 23 can store the excessive amount of refrigerant. When the external environment temperature rises, the heat pipe refrigeration system needs more refrigerant to circulate, and the refrigerant stored in the liquid storage device 23 participates in the refrigeration circulation, so that the refrigerator 1 can obtain better refrigeration effect under different external environment temperatures.

In some embodiments, the heat pipe refrigeration system further includes a capillary tube 24 disposed on the intake pipe 25 to throttle the refrigerant flowing from the condensation-side heat exchanger 21 to the evaporation-side heat exchanger 22. It is well known to those skilled in the art that the heat pipe itself has a capillary tube capable of throttling and depressurizing, and the capillary tube 24 can further enhance the throttling effect. Since the throttling function of the capillary 24 is readily known to those skilled in the art, it will not be described in detail herein.

That is, the subcooler 27, the accumulator 23 and the capillary tube 24 are all located in the refrigerant flow path from the condensation-side heat exchanger 21 to the evaporation-side heat exchanger 22. Further, the subcooler 27 is located closer to the condensing end heat exchanger 21 than the accumulator 23 and the capillary tube 24 so as to drive the refrigerant flowing out of the condensing end heat exchanger 21 to the evaporating end heat exchanger 22 in time. The capillary tube 24 is closer to the evaporation-side heat exchanger 22 than the reservoir 23.

In some embodiments, the evaporation end heat exchanger 22 may be disposed on a rear wall of the storage compartment 110 to facilitate heat exchange with air in the storage compartment 110. Specifically, the evaporation end heat exchanger 22 may be directly exposed in the storage compartment 110, or may be isolated from the storage compartment 110 by a partition, as long as the evaporation end heat exchanger 22 is located inside the insulating layer of the box body 10.

Specifically, the entirety of the inlet pipe 25 may extend vertically to facilitate the flow of liquid refrigerant upward along the inlet pipe 25. The pipe section of the air inlet pipe where the subcooler 27 is located may extend entirely vertically, the pipe section of the air inlet pipe where the reservoir 23 is located may extend laterally or obliquely downward, and the pipe section of the air inlet pipe where the capillary tube 24 is located may also extend laterally or obliquely downward. The muffler 26 may extend vertically to facilitate the flow of gaseous refrigerant vertically along the muffler 26, reducing refrigerant flow resistance.

In some embodiments, the refrigerator 1 further includes a blower 30, and the blower 30 is disposed at the bottom of the cabinet 10 and opposite to the condensation side heat exchanger 21 for driving the ambient air to flow toward the condensation side heat exchanger 21. Therefore, a larger amount of ambient air can be caused to flow to the condensation end heat exchanger 21 more quickly by the fan 30, so that the heat exchange efficiency between the condensation end heat exchanger 21 and the ambient air is improved, and the refrigeration efficiency of the refrigerator 1 is improved.

In some embodiments, the refrigerator 1 further includes a base 40, the base 40 being disposed under the cabinet 10 and having a bottom plate 41 extending in a lateral direction. The bottom plate 41 of the base 40 is disposed spaced apart from the bottom plate 11 of the cabinet 10 to define therebetween an accommodating space communicating with the external ambient space, in which the condensing-side heat exchanger 21 is disposed. Further, the fan 30 may also be disposed in the accommodating space. Therefore, the function of the condensation end heat exchanger 21 or the fan 30 can be prevented from being influenced by impurities such as dust and water falling on the condensation end heat exchanger.

Specifically, the horizontal periphery of the accommodating space formed between the base 40 and the box body 10 can be hollowed out, so that more ambient air can enter the accommodating space to contact with the condensation end heat exchanger 21, and the condensation end heat exchanger 21 is ensured to have a better heat exchange effect. At this time, the base 40 may be supported below the cabinet 10 by a plurality of support columns.

In some embodiments, the base 40 further includes at least two lateral side plates 42 extending vertically and disposed opposite to each other, the two lateral side plates 42 are respectively provided with an air inlet and an air outlet 43, and the fan 30 is disposed at the air inlet. The air inlet and the air outlet 43 can be arranged oppositely, so that the air flow driven by the fan 30 can flow out of the air outlet 43 without changing the direction after flowing through the condensation end heat exchanger 21, the flow resistance of the air flow is reduced, the flow speed of the air flow is improved, and the heat exchange effect of the condensation end heat exchanger 21 is further improved.

Further, the base 40 may further include other two opposite side plates to prevent a user from directly seeing the condensing end heat exchanger 21 in the accommodating space, so that the refrigerator 1 is more attractive.

In some embodiments, the refrigerator 1 further includes a temperature sensor 50, and the temperature sensor 50 is configured to detect a temperature of the external environment space, so as to adjust a rotation speed of the fan 30 according to the temperature of the external environment space, so that the rotation speed of the fan 30 matches the temperature of the external environment space, thereby ensuring that the condensing end heat exchanger 21 can obtain a good heat exchange effect in external environments with various temperatures. Specifically, when the temperature sensor 50 detects that the temperature of the external environment space is high, the refrigerator 1 may control the rotation speed of the fan 30 to be adjusted to a high level, so as to promote more ambient air to exchange heat with the condensation-side heat exchanger 21, and thus take away the heat emitted from the condensation-side heat exchanger 21 through more ambient air. When the temperature sensor 50 detects that the temperature of the external environment space is lower, the rotating speed of the controllable fan 30 of the refrigerator 1 is adjusted to a low level, at the moment, heat emitted by the condensing end heat exchanger 21 can be taken away by exchanging heat with the condensing end heat exchanger 21 through a small amount of ambient air, and therefore the environment adaptability of the refrigerator 1 is enhanced while energy is saved through matching and adjusting of fan gears under different ambient temperatures.

Further, temperature sensor 50 may be disposed at a front side of door 60 of refrigerator 1, or may be disposed on cabinet 10, as long as it can accurately detect the temperature of the external environment of refrigerator 1.
