[0002] At present, for refrigeration equipment such as freezers and refrigerators that have condensers installed in the compressor compartment, the heat dissipation method of the condenser is generally to install a cooling fan in the compressor compartment to form a heat dissipation airflow for forced convection heat exchange with the condenser, but this method also has certain defects. First, the heat dissipation structure mainly exchanges heat through the ambient temperature difference. Under harsh environmental conditions (when the ambient temperature difference is small), the heat dissipation effect is easily reduced and the refrigeration performance is weakened; secondly, the cooling fan is far away from the condenser, and the wind pressure loss is large, resulting in a decrease in wind speed and reduced heat dissipation performance; finally, the cooling fan itself will generate heat when working, which not only increases power consumption, but also increases the temperature of the compressor compartment.

[0003] The related art discloses a refrigeration and freezing device, which includes a box body and a compression refrigeration cycle system, wherein an installation space is formed at the bottom of the box body. The compression refrigeration cycle system also includes a first condenser and a radiator, wherein the first condenser is arranged in the installation space, and the radiator includes a heat exchange tube and an extension tube, wherein the heat exchange tube runs through the first condenser and is configured to exchange heat with the first condenser, and the extension tube extends from the heat exchange tube to the outside of the installation space to dissipate heat to the outside.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] Although the related technology abandons the traditional refrigerator's need to use a cooling fan to dissipate heat from the condenser, it adds a radiator device, and it is necessary to determine the installation position of the radiator according to the position of the first condenser or determine the installation position of the first condenser according to the position of the radiator to avoid mutual interference, making assembly more difficult.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0040] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0042] At present, for refrigeration equipment such as freezers and refrigerators that have condensers installed in the compressor compartment, the heat dissipation method of the condenser is generally to install a cooling fan in the compressor compartment to form a heat dissipation airflow for forced convection heat exchange with the condenser, but this method also has certain defects. First, the heat dissipation structure mainly exchanges heat through the ambient temperature difference. Under harsh environmental conditions (when the ambient temperature difference is small), the heat dissipation effect is easily reduced and the refrigeration performance is weakened; secondly, the cooling fan is far away from the condenser, and the wind pressure loss is large, resulting in a decrease in wind speed and reduced heat dissipation performance; finally, the cooling fan itself will generate heat when working, which not only increases power consumption, but also increases the temperature of the compressor compartment.

[0043] The related art discloses a refrigeration and freezing device, which includes a box body and a compression refrigeration cycle system, wherein an installation space is formed at the bottom of the box body. The compression refrigeration cycle system also includes a first condenser and a radiator, wherein the first condenser is arranged in the installation space, and the radiator includes a heat exchange tube and an extension tube, wherein the heat exchange tube runs through the first condenser and is configured to exchange heat with the first condenser, and the extension tube extends from the heat exchange tube to the outside of the installation space to dissipate heat to the outside.

[0044] Although the related technology abandons the traditional refrigerator's need to use a cooling fan to dissipate heat from the condenser, it adds a radiator device, and it is necessary to determine the installation position of the radiator according to the position of the first condenser or determine the installation position of the first condenser according to the position of the radiator to avoid mutual interference, making assembly more difficult.

[0045] Combination Figure 1 and Figure 2 As shown, the embodiment of the present disclosure provides a condenser 20 for a refrigeration device 10, including a composite pipeline structure 21. The composite pipeline structure 21 includes a first pipeline 211 and a second pipeline 212 parallel to the first pipeline 211 and connected to the pipe wall. The first pipeline 211 is configured to allow a refrigerant to flow through, and the second pipeline 212 is configured to allow a liquid with a temperature lower than the temperature of the refrigerant in the first pipeline 211 to flow through. The second pipeline 212 can cool the first pipeline 211.

[0046] The composite pipeline structure 21 of the condenser 20 for the refrigeration equipment 10 provided by the embodiment of the present disclosure is equivalent to increasing the heat dissipation area of ​​the condenser 20 and improving the heat dissipation speed. The first pipeline 211 is used to provide a circulation path for the refrigerant, and a low-temperature liquid circulates in the second pipeline 212. In this way, the temperature of the second pipeline 212 is lower than the temperature of the first pipeline 211. The two are parallel and connected to the pipe wall, and heat conduction can be carried out. The second pipeline 212 can absorb the heat emitted by the first pipeline 211, thereby reducing the temperature of the first pipeline 211 and meeting the heat dissipation requirements of the condenser 20. Moreover, the first pipeline 211 and the second pipeline 212 are both structures of the condenser 20 itself. The condenser 20 itself can cool the refrigerant pipeline, and there is no need to add a heat dissipation device in the related technology, which reduces the difficulty of assembly and improves the production speed of the refrigeration equipment 10.

[0047] Optionally, the second pipe 212 is configured to allow defrost water or coolant to flow through.

[0048] The second pipeline 212 is configured to allow defrost water to flow through, so that the defrost water can be reused. The temperature of the defrost water is relatively low, about 5°C, which is much lower than the ambient temperature of the condenser 20. In this way, the temperature difference between the first pipeline 211 and the second pipeline 212 is increased, and the heat exchange effect of the condenser 20 is enhanced. There is no need to use a cooling fan to force convection heat dissipation on the condenser 20, thereby reducing the energy consumption of the refrigeration equipment 10.

[0049] The second pipeline 212 can also be configured to allow coolant to flow through. In this way, when there is no defrost water or the defrost water produced is small, it is ensured that the second pipeline 212 continues to have liquid with a lower temperature than the refrigerant temperature in the first pipeline 211 flowing through it, maintaining the temperature difference between the second pipeline 212 and the first pipeline 211, so that the second pipeline 212 can continue to cool the first pipeline 211.

[0050] Optionally, combined Figures 2 to 4 As shown, the first pipeline 211 is a coiled structure, and the second pipeline 212 includes an inlet section 2121 and a cooling section 2122. The inlet section 2121 is configured to communicate with the water receiving box 30 of the refrigeration device 10. The cooling section 2122 is communicated with the inlet section 2121, and the cooling section 2122 is a coiled structure. The cooling section 2122 is parallel to the first pipeline 211 and is connected to the inner peripheral side pipe wall of the first pipeline 211.

[0051] By configuring the first pipeline 211 to have a coiled structure, the heat exchange area of ​​the first pipeline 211 can be increased, thereby accelerating the heat exchange speed.

[0052] The second pipeline 212 includes an inlet section 2121 , which is configured to communicate with the water receiving box 30 of the refrigeration device 10 , so that defrost water flows into the inlet section 2121 and the cooling section 2122 of the second pipeline 212 in sequence through the water receiving box 30 to cool the first pipeline 211 .

[0053] The cooling section 2122 is also configured as a coiled structure, which is parallel to the coiled structure of the first pipeline 211 and connected to the inner circumferential side pipe wall of the coiled structure of the first pipeline 211. In this way, the heat dissipation area of ​​the first pipeline 211 is further increased, and the heat exchange speed is faster.

[0054] Optionally, combined Figure 1 As shown, the height of the inlet section 2121 is higher than the height of the outlet of the second pipeline 212 .

[0055] In this way, a liquid level difference is formed between the inlet section 2121 and the outlet, and the liquid in the second pipeline 212 flows toward the outlet under the action of the liquid level difference, thereby realizing the flow of the liquid in the second pipeline 212 .

[0056] Optionally, combined Figure 2 As shown, the condenser 20 further includes a heat sink 22. The heat sink 22 is disposed on the side wall of the first pipeline 211, or the heat sink 22 is disposed on the side wall of the first pipeline 211 and the second pipeline 212.

[0057] By arranging the heat dissipation wire 22 on the side wall of the first pipeline 211 , the heat dissipation area of ​​the first pipeline 211 can be increased, the heat dissipation speed can be improved, and the temperature of the refrigerant in the first pipeline 211 can be quickly reduced.

[0058] The pipe walls of the first pipeline 211 and the second pipeline 212 are connected. The temperature of the first pipeline 211 is high, and the temperature of the second pipeline 212 is low. The heat in the first pipeline 211 can be transferred to the second pipeline 212. In this way, heat dissipation wires 22 are simultaneously arranged on the side walls of the first pipeline 211 and the second pipeline 212, which can not only increase the heat dissipation area of ​​the first pipeline 211 and the second pipeline 212, but also accelerate the heat dissipation speed of the second pipeline 212. The temperature of the second pipeline 212 increased due to heat exchange is rapidly reduced, and the second pipeline 212 continues to maintain a large temperature difference to exchange heat with the first pipeline 211, thereby improving the heat exchange efficiency of the second pipeline 212 and the first pipeline 211 and shortening the time required for the temperature of the refrigerant in the first pipeline 211 to reach the standard requirements.

[0059] Optionally, the heat sink 22 is disposed on a side wall of the first pipeline 211 that is away from the second pipeline 212 .

[0060] The second pipeline 212 is connected to the tube wall of the first pipeline 211 , and the heat sink 22 is arranged on the side wall of the first pipeline 211 away from the second pipeline 212 , which can avoid mutual interference in the positional relationship between the heat sink 22 and the second pipeline 212 and reduce the difficulty of assembling the heat sink 22 .

[0061] Optionally, combined Figure 2 and Figure 3 As shown, the first pipeline 211 includes a plurality of horizontal sections 2111, and the plurality of horizontal sections 2111 are vertically arranged in parallel. The heat dissipation wire 22 connects the plurality of horizontal sections 2111 on the same vertical plane.

[0062] It can be understood that the first pipeline 211 is a coiled structure, which includes a plurality of horizontal sections 2111 arranged vertically and in parallel, each of which is arranged from outside to inside or from inside to outside on its corresponding horizontal plane. The coiled structure also includes a vertically arranged connecting section 2114, which connects two adjacent horizontal sections 2111, and the horizontal sections 2111 and the connecting section 2114 together constitute the coiled structure.

[0063] The heat sink 22 connects multiple horizontal segments 2111 on the same vertical plane, that is, the direction of the heat sink 22 is consistent with the direction of the connecting segment 2114. Along the vertical direction, multiple vertically parallel horizontal segments 2111 arranged from the outside to the inside or from the inside to the outside are vertically connected as a whole, thereby reducing the number of heat sinks 22 required to connect multiple horizontal segments 2111 and making the appearance more neat.

[0064] Optionally, there are multiple heat sinks 22 connecting multiple horizontal segments 2111 on the same vertical plane, and the multiple heat sinks 22 are arranged at intervals along the extension direction of the horizontal segments 2111 on the vertical plane.

[0065] In this way, the heat dissipation area of ​​the multiple horizontal segments 2111 on the same vertical plane can be further increased, thereby accelerating the heat dissipation speed.

[0066] Optionally, the first pipeline 211 and the second pipeline 212 are connected by welding or clamping.

[0067] The first pipeline 211 and the second pipeline 212 are connected together by welding, so that the connection is more firm, and there is no need to consider complicated connection matching, and the structure is simpler.

[0068] The first pipeline 211 and the second pipeline 212 are connected together by a clamp. The connection structure is simple, and the first pipeline 211 and / or the second pipeline 212 can be replaced according to product requirements to meet requirements of various refrigeration specifications.

[0069] Combination Figure 1 and Figure 5As shown, the embodiment of the present disclosure provides a refrigeration device 10, including a box shell 40, an inner tank 50, a compressor 70, a condenser 20 and an evaporator 80. A compressor compartment 60 is jointly enclosed between the lower part of the inner tank 50 and the box shell 40, and the compressor 70 is arranged in the compressor compartment 60. The compressor 70 includes a first input end 71 and a first output end 72. The condenser 20 is arranged in the compressor compartment 60. The first pipeline 211 includes a second input end 2112 and a second output end 2113, and the second input end 2112 is connected to the first output end 72. The evaporator 80 is arranged between the second output end 2113 and the first input end 71, and the evaporator 80 is located downstream of the second output end 2113.

[0070] In this way, the compressor 70, the evaporator 80 and the condenser 20 are connected through the refrigerant pipeline. Starting from the compressor 70, the refrigerant flows through the first output end 72, the second input end 2112, the condenser 20, the second output end 2113, the evaporator 80 in sequence, and then returns to the compressor 70 through the first input end 71, realizing the refrigeration cycle.

[0071] The refrigeration device 10 further includes a throttling device 90, which is disposed between the second output terminal 2113 and the evaporator 80 and is located upstream of the evaporator 80. The compressor 70, the condenser 20, the throttling device 90 and the evaporator 80 constitute a refrigeration system.

[0072] The compressor 70 in the refrigeration system mainly absorbs the low-temperature and low-pressure refrigerant gas from the evaporator 80, which is eventually converted into high-temperature and high-pressure refrigerant after adiabatic compression by the compressor 70.

[0073] The role of the condenser 20 in the refrigeration system is to introduce the high-temperature and high-pressure refrigerant in the compressor 70 into the condenser 20, condense the refrigerant under the same pressure, and dissipate heat to the surrounding medium, turning it into a high-pressure and low-temperature refrigerant liquid.

[0074] The role of the throttling device 90, such as a capillary tube, in the refrigeration system is mainly to convert the high-pressure and low-temperature refrigerant liquid into a low-temperature and low-pressure refrigerant after isenthalpic throttling, and then send the refrigerant into the evaporator 80.

[0075] The evaporator 80 in the refrigeration system mainly plays the role of boiling the low-temperature and low-pressure refrigerant passing through the throttling device 90 under the condition of equal pressure in the evaporator 80. During the boiling process, the refrigerant will absorb the heat of the surrounding medium and eventually become a low-temperature and low-pressure refrigerant gas.

[0076] In summary, the refrigerant gas in the compressed refrigeration system is compressed into a high-temperature and high-pressure superheated refrigerant when passing through the compressor 70, and enters the condenser 20. The high-temperature and high-pressure refrigerant is condensed into a high-pressure and low-temperature liquid in the condenser 20. After that, this liquid enters the filter and passes through the throttling device 90, etc., and is throttled in the capillary tube to become a low-temperature and low-pressure refrigerant. After that, this low-temperature and low-pressure refrigerant boils in the isobaric evaporator 80, absorbs a large amount of external heat, and becomes a gas, realizing the refrigeration process. Finally, the refrigerant is sucked into the compressor 70 again for the refrigeration cycle.

[0077] Optionally, combined Figures 1 to 4 As shown, a drain port 51 is provided at the bottom of the inner tank 50, and the refrigeration device 10 further includes a water receiving box 30 and an evaporating dish 100. The water receiving box 30 is provided at the drain port 51, and is used to receive defrosting water generated by the evaporator 80. The evaporating dish 100 is provided in the compressor compartment 60, and the evaporating dish 100 is located below the condenser 20. The second pipeline 212 further includes an outflow section 2123, one end of the outflow section 2123 is connected to the cooling section 2122, and the other end is connected to the evaporating dish 100, so as to transfer the defrosting water of the cooling section 2122 to the evaporating dish 100.

[0078] The first pipeline 211 and the second pipeline 212 are parallel and connected with each other through the pipe walls. The temperature difference between the two pipelines is used to cool the refrigerant in the first pipeline 211 and evaporate the defrost water in the second pipeline 212. The unevaporated defrost water in the second pipeline 212 enters the evaporating dish 100 through the outflow section 2123 and evaporates naturally.

[0079] Optionally, the refrigeration device 10 is a refrigerator or a freezer. The freezer includes a horizontal freezer and a vertical freezer. A refrigeration space is defined above the inner tank 50, and the evaporator 80 is arranged in the refrigeration space.
