Description

Technical Field

[0001] This utility model belongs to the field of refrigerator refrigeration technology, and in particular relates to a refrigeration component and a refrigerator. Background Technology

[0002] Currently, most refrigerators use a bottom-supply, top-return airflow pattern in the refrigerator compartment. This pattern results in a significantly higher temperature at the top of the compartment compared to other areas, leading to uneven temperature distribution. Furthermore, the temperature sensor used to detect the refrigerator compartment temperature is typically installed in the middle of the compartment's height. This causes the sensor to inaccurately reflect the actual temperature inside the compartment, resulting in a systematic deviation between the actual and set temperatures. Utility Model Content

[0003] In view of this, it is necessary to provide a refrigeration component and refrigerator for solving the above-mentioned technical problems.

[0004] A refrigeration component for use in a refrigerator, the refrigeration component comprising:

[0005] The refrigerator inner liner has an air outlet, an air return outlet, and an air return duct. The air return outlet is located above the air outlet in the height direction of the refrigerator, and the air return outlet is connected to the air outlet through the air return duct.

[0006] A refrigerated evaporator is installed inside the return air duct;

[0007] A heat pipe is partially disposed within the return air duct. The portion of the heat pipe located within the return air duct is thermally connected to the refrigerated evaporator. The end of the heat pipe furthest from the refrigerated evaporator extends out of the return air duct through the return air inlet.

[0008] Understandably, by utilizing the heat conduction of the heat pipe, the refrigeration unit can directly transfer the cooling energy of the evaporator to the return air vent of the refrigerator liner. This allows for a more even temperature distribution within the refrigerator compartment and more accurate temperature measurements, which in turn helps the refrigerator's temperature control system provide precise feedback.

[0009] In one embodiment, the heat pipe is welded to the refrigerated evaporator, and the heat pipe is thermally connected to the refrigerated evaporator.

[0010] It is understandable that welding is used to achieve the assembly and heat conduction between the heat pipe and the refrigeration evaporator, which simplifies the assembly process.

[0011] In one embodiment, the refrigerated inner liner encloses and forms a refrigerated compartment, and the air outlet and the air return outlet are respectively connected to the refrigerated compartment;

[0012] Furthermore, the heat pipe has a hot end that can extend into the cold storage room via the return air vent.

[0013] In one embodiment, the hot end is horizontal.

[0014] In one embodiment, the hot end is disposed against the top wall of the cold storage compartment.

[0015] Understandably, placing the hot end of the heat pipe against the ceiling wall of the refrigerator compartment, making it in a less noticeable position, serves two purposes: firstly, it conceals the hot end and reduces its impact on the refrigerator's cooling capacity; secondly, the ceiling wall of the refrigerator compartment provides additional support for the hot end of the heat pipe.

[0016] In one embodiment, the number of heat pipes and the number of return air vents are both configured to be multiple, with multiple heat pipes corresponding one-to-one with multiple return air vents, and the hot end of the heat pipe can extend into the cold storage room from the corresponding return air vent.

[0017] In one embodiment, the return air vent is permeated by multiple heat pipes.

[0018] In one embodiment, the return air vent is located at the top of the refrigerator liner, and the air outlet is located at the bottom of the refrigerator liner.

[0019] In one embodiment, the refrigeration assembly further includes a temperature sensor located at the midpoint between the return air vent and the air outlet in the height direction of the refrigerator. The temperature sensor is used to detect the ambient temperature of the refrigeration compartment inside the refrigeration liner and generate a feedback signal, which is used to control the operation of the refrigeration evaporator.

[0020] This application also provides a refrigerator, including the refrigeration components described above.

[0021] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0022] The refrigeration unit and refrigerator claimed in this application utilize heat conduction through heat pipes, enabling the refrigeration unit to directly transfer the cooling capacity of the evaporator to the return air vent of the refrigerator liner. This results in a more even temperature distribution within the refrigerator compartment and more accurate temperature measurement, which is beneficial for the refrigerator's temperature control system to provide precise feedback.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] like Figure 1As shown, the refrigeration assembly 100 provided in this application includes a refrigerator liner 10, a refrigerator evaporator 20, and a heat pipe 30. The refrigerator liner 10 has an air outlet 11, a return air inlet 12, and a return air duct 13. The return air inlet 12 is located above the air outlet 11 in the height direction Z of the refrigerator, and the return air inlet 12 is connected to the air outlet 11 through the return air duct 13, realizing a bottom-to-top air supply mode for the refrigerator liner 10. The refrigerator evaporator 20 is disposed within the return air duct 13. A portion of the heat pipe 30 is disposed within the return air duct 13, and the portion of the heat pipe 30 located within the return air duct 13 is thermally connected to the refrigerator evaporator 20. One end of the heat pipe 30, away from the refrigerator evaporator 20, extends out of the return air duct 13 through the return air inlet 12. Here, the return air inlet 12 is located at the top of the refrigerator liner 10, and the air outlet 11 is located at the bottom of the refrigerator liner 10. It should be noted that the heat pipe 30 mentioned above is thermally connected to the refrigeration evaporator 20, specifically meaning that the heat pipe 30 can exchange heat with the refrigeration evaporator 20.

[0031] As can be seen from the above, in the refrigeration component 100 of this application, the refrigeration evaporator 20 delivers cold energy to the refrigeration compartment 110 of the refrigeration inner liner 10 through the air outlet 11, and can also use the heat conduction of the heat pipe 30 to directly transfer the cold energy to the position of the return air vent 12 of the refrigeration inner liner 10. This makes the internal temperature distribution of the refrigeration compartment 110 of the refrigeration inner liner 10 more balanced and the temperature measured in the refrigeration compartment 110 more accurate, which is beneficial for the refrigerator refrigeration temperature control system to provide accurate feedback.

[0032] It should be noted that the heat pipe 30 of this application is filled with a low-boiling-point solution. Utilizing the phase change of the solution, the heat pipe 30 can absorb heat from the return air vent 12 of the refrigerator liner 10 and conduct the absorbed heat to the refrigerator evaporator 20 for heat exchange. This achieves the purpose of uniformizing the internal temperature of the refrigerator compartment 110 of the refrigerator liner 10. Specifically, the low-boiling-point solution filled in the heat pipe 30 can be isobutane, ammonia, propane, tetrafluoroethane, ethanol, etc., which will not be elaborated upon here.

[0033] like Figure 2 As shown, in one embodiment, the heat pipe 30 is connected to the refrigerated evaporator 20 by welding, thus achieving a thermal connection between the heat pipe 30 and the refrigerated evaporator 20. That is, by welding the heat pipe 30 to the refrigerated evaporator 20, not only is the assembly connection between the heat pipe 30 and the refrigerated evaporator 20 achieved, but also the thermal connection between the heat pipe 30 and the refrigerated evaporator 20, which simplifies the assembly process. It is understood that in other embodiments, the heat pipe 30 can also be assembled and connected to the refrigerated evaporator 20 using other connectors such as clips. Here, three heat pipes 30 are configured, and each of the three heat pipes 30 is welded to the heat exchange tube 21 of the refrigerated evaporator 20.

[0034] like Figure 1 As shown, in one embodiment, the refrigerator liner 10 encloses a refrigerator compartment 110, with an air outlet 11 and an air return outlet 12 respectively connected to the refrigerator compartment 110. Furthermore, the heat pipe 30 has a hot end 31, which extends into the refrigerator compartment 110 via the air return outlet 12. That is, in this embodiment, the heat pipe 30 extends into the interior of the refrigerator compartment 110, thereby increasing the contact area between the hot end 31 and the air inside the refrigerator compartment 110. This improves the cooling effect on the refrigerator compartment 110 within the refrigerator liner 10 in the plane area where the air return outlet 12 is located, ensuring a more uniform temperature distribution within the refrigerator compartment 110. Here, the hot end 31 of the heat pipe 30 extends to the relative position of the refrigerator liner 10 at the air return outlet 12. It should be noted that the hot end 31 of the heat pipe 30 specifically refers to the end of the heat pipe 30 used for cooling the refrigerator compartment 10 at the location of the air return outlet 12.

[0035] like Figure 1 , Figure 2 As shown, in this embodiment, the hot end 31 is horizontal. Preferably, the hot end 31 is disposed against the top wall 111 of the refrigerator compartment 110, so that the hot end 31 of the heat pipe 30 is disposed in a position that is not easily noticed in the refrigerator compartment 110. This can, on the one hand, conceal the hot end 31 and reduce the impact of the hot end 31 on the refrigeration capacity of the refrigerator compartment 110; on the other hand, the top wall 111 of the refrigerator compartment 110 can also provide auxiliary support for the hot end 31 of the heat pipe 30, thereby protecting the hot end 31 of the heat pipe 30 located in the refrigerator compartment 110.

[0036] like Figure 2 As shown, in one embodiment, the number of heat pipes 30 and return air vents 12 are both configured to be multiple, with multiple heat pipes 30 corresponding one-to-one with multiple return air vents 12, and the hot end 31 of the heat pipe 30 can extend into the refrigerator compartment 110 from the corresponding return air vent 12. That is to say, in this embodiment, the refrigerator assembly 100 has a heat pipe 30 arranged at each return air vent 12 position of the refrigerator liner 10, which can improve the cooling effect of the refrigerator compartment 110 in the plane area where the return air vent 12 is located, and ensure a more uniform temperature distribution inside the refrigerator compartment 110 of the refrigerator liner 10.

[0037] It should be noted that the relationship between the heat pipe 30 and the return air vent 12 is not limited to the one-to-one correspondence described above. For those skilled in the art, multiple heat pipes 30 can be installed through the return air vent 12. That is, multiple heat pipes 30 can pass through each return air vent 12 at the same time. Therefore, the opening size of the return air vent 12 of the refrigerator liner 10 can be set to be large enough, which will not be elaborated here.

[0038] In this application, the refrigeration assembly 100 also includes a temperature sensor (not shown). The temperature sensor is located at the middle of the return air vent 12 and the air outlet vent 11 in the height direction of the refrigerator. It is used to detect the ambient temperature of the refrigeration compartment 110 inside the refrigeration liner 10 and generate a feedback signal. The feedback signal is used to control the operation of the refrigeration evaporator 20.

[0039] In addition, this application also provides a refrigerator, including the refrigeration component 100 described above.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
