Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a heat exchanger assembly and a refrigerator. Background Technology

[0002] The heat exchanger is an important component in a refrigerator. It transfers heat from the air inside the refrigerator to the outside through the heat exchange and transfer of the refrigerant, thereby regulating the internal temperature of the refrigerator.

[0003] In related technologies, heat exchangers in refrigerators are typically assembled using welding processes. However, when a heat exchanger malfunctions and requires repair, technicians must first drain the refrigerant from the refrigerator, then re-weld it, followed by evacuation and refilling with Freon refrigerant. This series of steps is not only difficult to assemble and time-consuming, but also highly prone to refrigerant waste. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a heat exchanger assembly and a refrigerator.

When the heat exchanger needs to be disassembled, the first and second shut-off valves are closed first to isolate the refrigerant in the refrigerator body from the heat exchanger body. Then, the first connecting part and the inlet end, as well as the second connecting part and the outlet end, are disassembled. Since the amount of refrigerant in the first connecting part, the second connecting part, and the heat exchanger body is relatively small, the refrigerant loss is small, which can reduce the waste of refrigerant in the refrigerator body. When the heat exchanger needs to be assembled, a small amount of refrigerant is injected into the heat exchanger body first. Then, the first connecting part and the inlet end, as well as the second connecting part and the outlet end are connected.

[0035] To facilitate understanding of the present application, the spline curves and arrows used in the reference numerals in the accompanying drawings are explained below: spline curves without arrows indicate solid parts, that is, parts with solid structures; spline curves with arrows indicate virtual parts, that is, parts without solid structures.

[0036] Firstly, please refer to Figure 1 , Figure 2 and Figure 3 This application provides a heat exchanger assembly 100, including: a heat exchanger body 10, with an inlet end 11 and an outlet end 12 on the heat exchanger body 10; a first connecting part 21 and a second connecting part 22, the first connecting part 21 being detachably connected to the inlet end 11 and the second connecting part 22 being detachably connected to the outlet end 12; and a first shut-off valve 31 and a second shut-off valve 32, the two ends of the first shut-off valve 31 being fixedly connected to the first connecting part 21 and the refrigerator body respectively, and the two ends of the second shut-off valve 32 being fixedly connected to the second connecting part 22 and the refrigerator body respectively.

[0037] The heat exchanger assembly 100 provided in this application connects the first shut-off valve 31 and the inlet end 11 of the heat exchanger body 10 via a first connecting part 21, and the second connecting part 22 connects the second shut-off valve 32 and the outlet end 12 of the heat exchanger body 10. When the heat exchanger needs to be disassembled, the first shut-off valve 31 and the second shut-off valve 32 are closed first to isolate the refrigerant in the refrigerator body from the heat exchanger body 10. Then, the first connecting part 21 and the inlet end 11, and the second connecting part 22 and the outlet end 12 are disassembled. Since the amount of refrigerant in the first connecting part 21, the second connecting part 22, and the heat exchanger body 10 is small, the refrigerant loss is small, which can reduce the waste of refrigerant in the refrigerator body. When the heat exchanger needs to be assembled, a small amount of refrigerant is injected into the heat exchanger body 10 first. Then, the first connecting part 21 and the inlet end 11, and the second connecting part 22 and the outlet end 12 are connected. Then, the first shut-off valve 31 and the second shut-off valve 32 are opened to connect the refrigerator body and the heat exchanger, and the refrigerant flows and exchanges heat in the refrigerator body and the heat exchanger.

[0038] The heat exchanger assembly 100 provided in this application has a simple structure, high efficiency and low cost in assembling and disassembling the heat exchanger, and can effectively reduce refrigerant loss, making it green and environmentally friendly.

[0039] In some embodiments, the first connecting portion 21 includes a first connecting pipe 211 and a first connector 212 sleeved on one end of the first connecting pipe 211. The end of the first connecting pipe 211 away from the first connector 212 is fixedly connected to the first shut-off valve 31, and the first connector 212 is detachably connected to the inlet end 11. It can be understood that the first connecting pipe 211 is used to form a channel for refrigerant flow, and the first connector 212 is used to connect to the inlet end 11.

[0040] It should be noted that the first connector 212 and the inlet end 11 are detachably connected. When the first connector 212 and the inlet end 11 are connected, the connection structure between the first connector 212 and the inlet end 11 is a sealed structure. In other words, there is no gap between the first connector 212 and the inlet end 11, or there is a very small gap due to actual operation, in order to avoid refrigerant leakage.

[0041] In some embodiments, the end of the first connecting pipe 211 near the inlet end 11 is flared. Specifically, the outer diameter of the end of the first connecting pipe 211 away from the inlet end 11 is smaller than the inner diameter of the first connector 212, so that the first connector 212 is fitted onto the first connecting pipe 211. The outer diameter of the flared first connecting pipe 211 is larger than the inner diameter of the end of the first connector 212 away from the inlet end 11. After the first connector 212 is fitted onto the first connecting pipe 211 through the end with the smaller inner diameter, it moves toward the end with the larger inner diameter of the first connecting pipe 211. The flared portion of the first connecting pipe 211 abuts against the first connector 212, limiting the contact of the first connector 212. The flared shape can effectively seal the connection, preventing refrigerant from leaking from the gap between the first connector 212 and the first connecting pipe 211.

[0042] In some embodiments, the first connector 212 is a ferrule connector. Ferrule connectors are convenient and quick to connect, reducing installation time. Furthermore, ferrule connectors offer high connection rigidity, are less prone to loosening, and provide a stable and reliable connection. When disassembling the first connector 212 and the inlet end 11, a wrench can be used to loosen the ferrule connector to disassemble the heat exchanger.

[0043] Furthermore, the inner surface of the connector away from the inlet end 11 is provided with a chamfered surface, which is used to cooperate with the flared part of the first connecting pipe 211, so that the connection between the first connecting pipe 211 and the first connector 212 is more stable, effectively improving the sealing performance of the connection and reducing the waste of refrigerant.

[0044] In some embodiments, the first connecting portion 21 and the inlet end 11 are threadedly connected. Specifically, the first connector 212 and the inlet end 11 are threadedly connected.

[0045] It should be noted that in related technologies, the inlet end 11 and outlet end 12 of the heat exchanger body 10 are usually made of copper tubes, which are connected to the refrigerator body by welding. The copper tubes used in the inlet end 11 and outlet end 12 of the heat exchanger body 10 provided in this application are thicker and have 1 / 4 external threads machined to mate with the internal threads of the first connector 212.

[0046] In other embodiments, the first connecting portion 21 has an external thread and the inlet end 11 has an internal thread.

[0047] It is understood that the first connecting part 21 and the inlet end 11 can also be connected by other detachable connection methods conventional in the art.

[0048] In some embodiments, the second connection portion 22 includes a second connecting pipe 221 and a second connector 222 sleeved on one end of the second connecting pipe 221. The end of the second connecting pipe 221 away from the second connector 222 is fixedly connected to the second shut-off valve 32, and the second connector 222 is detachably connected to the outlet end 12. In the second connection portion 22, the second connecting pipe 221 and the second connector 222 can refer to the first connecting pipe 211 and the first connector 212.

[0049] Specifically, in some embodiments, the end of the second connecting pipe 221 near the outlet end 12 is flared.

[0050] In some embodiments, the second connector 222 is a ferrule connector.

[0051] In some embodiments, the second connecting portion 22 and the outlet end 12 are threadedly connected. Specifically, the second connector 222 and the outlet end 12 are threadedly connected.

[0052] In some embodiments, the heat exchanger body 10 is provided with a heat exchange tube, and the inlet end 11, the heat exchange tube and the outlet end 12 are connected in sequence.

[0053] In some embodiments, the heat exchanger assembly 100 further includes a mounting base 40 on which the heat exchanger body 10 is disposed. Further, the distance between the mounting base 40 and the outlet end 12 is less than the distance between the mounting base 40 and the inlet end 11. In other words, the mounting base 40 is closer to the outlet end 12, which facilitates the mounting base 40 in supporting the heat exchanger body 10.

[0054] In some embodiments, the mounting base 40 is provided with a connecting portion 41 for fixed connection with the refrigerator body. The connection between the mounting base 40 and the refrigerator body helps to fix the heat exchanger body 10 and prevent the heat exchanger body 10 from shaking and generating noise inside the refrigerator.

[0055] Secondly, embodiments of this application also provide a refrigerator, which includes the heat exchanger assembly 100 described above.

[0056] It should be noted that the heat exchanger body 10 includes a condenser and / or an evaporator. During the refrigerator's cooling operation, the refrigerant, in gaseous form, is drawn into the refrigerator's compressor, compressed into high-temperature, high-pressure vapor, and then enters the condenser through the exhaust pipe. The refrigerant dissipates heat into the outside air, condenses into a high-pressure liquid, passes through a filter into a capillary tube, and is depressurized before entering the evaporator to vaporize. The refrigerant liquid absorbs heat from the outside and vaporizes into dry saturated vapor, achieving cooling inside the refrigerator. After the refrigerant becomes low-pressure superheated vapor, it is drawn back into the compressor, and this process repeats. In other words, when the refrigerator's condenser is the aforementioned heat exchanger, the condenser's inlet end 11 is connected to the compressor's outlet end, and the condenser's outlet end 12 is connected to the capillary tube's inlet end; when the refrigerator's evaporator is the aforementioned heat exchanger, the evaporator's inlet end 11 is connected to the capillary tube's outlet end, and the evaporator's outlet end 12 is connected to the compressor's inlet end.

[0057] When the refrigerator provided in this application needs to be repaired or replaced due to aging of the heat exchanger body 10, the heat exchanger can be removed by controlling the closure of the first shut-off valve 31 and the second shut-off valve 32, and then disassembling the first connecting part 21 from the inlet end 11 of the heat exchanger body 10 and the second connecting part 22 from the outlet end 12 of the heat exchanger body 10. When reassembling, a small amount of refrigerant is first injected into the heat exchanger body 10 to purge air, the first connecting part 21 is connected at the inlet end 11 of the heat exchanger body 10 and the second connecting part 22 is connected at the outlet end 12 of the heat exchanger body 10, and then the first shut-off valve 31 and the second shut-off valve 32 are opened. The operation is simple and convenient, highly efficient, and can effectively reduce the waste of refrigerant.

Obviously, for those skilled in the art, the detailed disclosure above is merely illustrative and does not constitute a limitation of this application. Although not explicitly stated herein, those skilled in the art may make various modifications, improvements, and corrections to this application.
