[0042] Furthermore, the terms "disposed," "connected," and "fixed" should be interpreted broadly. For example, "connected" can mean a fixed connection, a removable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediary, or an internal connection between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in the embodiments of this disclosure based on the specific circumstances.

[0043] Unless otherwise stated, the term "plurality" means two or more.

[0044] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0046] Combine Figures 1 to 12 As shown, the embodiment of the present disclosure provides a heat exchanger assembly, such as Figures 2 to 6 As shown, the heat exchanger assembly includes a heat exchanger 20 and a partition 30. The heat exchanger 20 includes heat exchange tubes 202 and heat exchange fins 201. Multiple heat exchange fins 201 are arranged side by side, and the heat exchange tubes 202 pass through the multiple heat exchange fins 201. The partition 30 is located between two adjacent heat exchange fins 201 and is used to divide the heat exchanger 20 into multiple heat exchange sections.

[0047] In the disclosed embodiment, the partition member 30 is located between adjacent heat exchange fins 201. This allows the partition member 30 to be installed in the gaps between the heat exchange fins 201, thereby improving the partitioning effect of the partition member 30. The partition member 30 can be used to separate the heat exchanger 20 into multiple heat exchange sections. These multiple heat exchange sections can correspond to different compartments, preventing odor transfer between compartments. This eliminates the need for multiple heat exchangers 20, reduces structural complexity, reduces costs, and improves production and installation convenience.

[0048] Optionally, the heat exchange tube is an integrated structure, and the heat exchange tube 202 is bent and reciprocates through the plurality of heat exchange fins 201, which can increase the heat exchange area of ​​the heat exchanger and improve the heat exchange efficiency.

[0049] Optionally, the airflow in the spaces where the multiple heat exchange units are located is not connected. In this way, the airflow outside each heat exchange unit is relatively independent, thus avoiding airflow between the multiple heat exchange units. The multiple compartments corresponding to the multiple heat exchange units can operate and cool independently, and odor transfer between different compartments can be avoided.

[0050] Optionally, the heat exchanger assembly is adapted to be located within the heat exchanger cavity, and the partition member can divide the heat exchanger cavity into a plurality of chambers, the number of which is equal to the number of heat exchange parts and corresponds one to one. In this way, each chamber is not connected to each other, thereby achieving a disconnected airflow in the spaces where the multiple heat exchange parts are located.

[0051] In some optional embodiments, the heat exchanger 20 is suitable for being located in a heat exchanger cavity, and the outer wall surface of the partition member 30 is suitable for being in contact with (fitting with or close to) the inner wall surface of the heat exchanger cavity.

[0052] In the disclosed embodiment, the heat exchanger 20 is located in the heat exchanger cavity, and the airflow in the heat exchanger cavity can flow through the heat exchanger 20 and exchange heat with the heat exchanger 20 before flowing into the corresponding compartment. The outer wall surface of the partition 30 is in contact with the inner wall surface of the heat exchanger cavity, so that the multiple heat exchange parts are completely isolated from each other, and the cooling capacity of different heat exchange parts is prevented from diffusing from the gap between the partition 30 and the heat exchanger cavity. In some cases, due to the limitations of the production process, the outer wall surface of the partition can also be close to the inner wall surface of the heat exchanger cavity. There is a small gap between the partition and the heat exchanger cavity, which can also play the role of independent work and prevent odor.

[0053] Optionally, the outer edge of the partition 30 protrudes from the outer edge of the heat exchange fin 201 .

[0054] In the disclosed embodiment, the outer edge of the partition member 30 protrudes from the outer edge of the heat exchange fin 201, so that the partition member 30 can completely isolate two adjacent heat exchange parts to prevent the diffusion of cold energy.

[0055] In some alternative embodiments, the cavity wall of the heat exchanger cavity is provided with a partition fitting, which can abut against the partition to divide the heat exchanger cavity into multiple independent chambers, and different heat exchange portions are located in different chambers.

[0056] Optionally, as shown in Figure 5 and Figure 6 The partition 30 includes a first partition 301 and a second partition 302, and the first partition 301 and the second partition 302 are detachably connected.

[0057] In the embodiments of the present disclosure, the partition 30 includes the first partition 301 and the second partition 302 which are detachably connected, so that the installation and disassembly of the partition 30 are facilitated, and the partition 30 can be installed on the heat exchanger 20 after the heat exchanger 20 is manufactured, thereby improving the application range and flexibility of the partition 30.

[0058] Optionally, the first partition 301 and the second partition 302 are insertedly connected. The insertion connection facilitates the connection and separation of the first partition 301 and the second partition 302, and facilitates the operation.

[0059] Optionally, the first partition 301 and the second partition 302 are insertedly connected along the width or length direction of the heat exchange fin 201; wherein the end of the first partition 301 towards the second partition 302 is provided with an insertion protrusion 304, and the end of the second partition 302 towards the first partition 301 is provided with an insertion groove 303, and when the first partition 301 and the second partition 302 are connected, the insertion protrusion 304 is located in the insertion groove 303.

[0060] In the embodiments of the present disclosure, the first partition 301 and the second partition 302 are insertedly connected along the width or length direction of the heat exchange fin 201, so that the first partition 301 and the second partition 302 are facilitated to be installed on the heat exchanger 20, and the insertion protrusion 304 and the insertion groove 303 are insertedly connected, and the first partition 301 and the second partition 302 do not need to be twisted and matched, thereby improving the convenience of disassembly and installation of the first partition 301 and the second partition 302.

[0061] Optionally, the number of the insertion protrusions 304 is multiple, and the multiple insertion protrusions 304 are sequentially and spacedly arranged along the height direction of the first partition, and the number of the insertion grooves 303 is the same as and corresponds to the number of the insertion protrusions 304. In this way, the connection stability of the first partition 301 and the second partition 302 can be improved.

[0062] Optionally, the first partition 301 and the second partition 302 can also be detachably connected by clamping, magnetic attraction or screw connection.

[0063] Optionally, a first through groove 3051 is constructed at the end of the first partition piece 301 facing the second partition piece 302, and a second through groove 3052 is constructed at the end of the second partition piece 302 facing the first partition piece 301. When the first partition piece 301 and the second partition piece 302 are connected, the first through groove 3051 and the second through groove 3052 enclose a through hole 305, and the heat exchange tube 202 is located in the through hole 305.

[0064] In the embodiment of the present disclosure, the first partition member 301 and the second partition member 302 enclose a through hole 305 to facilitate the passage of the heat exchange tube 202 , thereby ensuring the flow of refrigerant throughout the heat exchanger 20 and ensuring the heat exchange performance of the heat exchanger 20 .

[0065] Optionally, the plug-in protrusion 304 is provided at the end of the first through groove 3051 facing the second partition piece 302, and the plug-in groove 303 is provided at the end of the second through groove 3052 facing the first partition piece, so that when the plug-in protrusion 304 is plugged into the plug-in groove 303, the first partition piece 301 and the second partition piece 302 are connected, and the first through groove 3051 and the second through groove 3052 enclose the through hole 305.

[0066] Optionally, the heat exchange tube 202 matches the through hole 305 , which can ensure the insulation effect of the partition member 30 to the greatest extent.

[0067] Optionally, the partition member 30 is an integrated structure, which is simple in structure and easy to produce. For example, the partition member 30 can be an integrated plate-shaped structure, which can separate the heat exchanger into multiple heat exchange parts.

[0068] Alternatively, as Figure 7 and Figure 8 As shown, the partition 30 defines an installation cavity 306 therein, and the heat exchanger assembly further includes a seal 40 , which is located in the installation cavity 306 and is used to reduce or isolate the cold transfer between the multiple heat exchange parts.

[0069] In the disclosed embodiment, the partition member 30 defines a mounting cavity 306, which increases the thickness of the partition member 30. The mounting cavity 306 is filled with air, further enhancing the insulation performance of the partition member 30. A seal 40 is also provided within the mounting cavity 306, further enhancing the overall thermal insulation performance of the partition member 30 and ensuring the independence of the multiple heat exchange components.

[0070] Optionally, the seal 40 is a rubber seal.

[0071] Optionally, the sealing member 40 corresponds to the through hole 305 to seal the through hole 305 .

[0072] In the embodiment of the present disclosure, the through hole 305 facilitates the heat exchange tube 202 to pass through the partition 30. The sealing member 40 is arranged at the through hole 305, which can not only increase the insulation effect of the partition 30, but also further seal the through hole 305 to prevent the cold from diffusing from the through hole 305.

[0073] Optionally, the cross-sectional area of ​​the sealing member 40 is greater than or equal to the cross-sectional area of ​​the through hole 305 , so as to completely prevent the cold energy leakage from the through hole 305 .

[0074] Optionally, the outer wall surface of the sealing member 40 is in contact with the inner wall surface of the partition member 30. This ensures that there is no gap between the sealing member 40 and the inner wall surface of the partition member 30, thereby preventing cold leakage.

[0075] Optionally, the sealing member 40 is attached to the wall surface of the through hole 305 facing the installation cavity to prevent air leakage from the through hole 305 .

[0076] Optionally, the seal 40 is clamped between two adjacent heat exchange tubes 202. This facilitates the fixation of the seal 40 and prevents the seal 40 from moving within the mounting cavity 306 during transportation of the heat exchanger 20, thereby ensuring a good sealing effect. Furthermore, the seal 40 is clamped between two adjacent heat exchange tubes 202 so that the seal 40 does not interfere with the heat exchange tubes 202, allowing the heat exchange tubes 202 to pass smoothly through the partition 30.

[0077] Optionally, a snap-in hole is constructed at the end of the seal 40, and the heat exchange tube 202 is located in the snap-in hole, and the heat exchange tube 202 fits against the inner wall surface of the snap-in hole, so that there is no gap between the heat exchange tube 202 and the seal 40, so that the coldness and odor of the heat exchange part cannot spread to the adjacent heat exchange part through the through hole 305 and the heat exchange tube 202, so that the adjacent heat exchange parts are completely isolated, sealed and independent, thereby making different compartments independent and avoiding odor contamination.

[0078] Optionally, the partition 30 is provided with a plurality of through holes 305 , and the number of the sealing members 40 is the same as the number of the through holes 305 and corresponds one to one, so that both the arrangement of a plurality of heat exchange tubes 202 and the completeness of the sealing and isolation can be ensured.

[0079] Alternatively, as Figure 2 、 Figure 3 and Figure 10 As shown, the heat exchanger assembly further includes a heating wire 70 , which is disposed on at least one side of the heat exchanger 20 for heating and defrosting the heat exchanger 20 .

[0080] Optionally, the heat exchanger assembly further includes a heat insulating member 60 , which is disposed between the partition member 30 and the heating wire 70 .

[0081] In the embodiment of the present disclosure, the thermal insulation member 60 can isolate the heat transfer between the heating wire 70 and the partition member 30, thereby preventing the heating wire 70 from heating for a long time and causing safety hazards such as fire.

[0082] Optionally, the thermal insulation member 60 is made of metal material.

[0083] Optionally, the thermal insulation member 60 is an aluminum foil tape.

[0084] Optionally, the ratio of the area of ​​one heat exchange portion to the area of ​​the heat exchanger is greater than or equal to 1 / 6 and less than 1.

[0085] In the disclosed embodiment, if the ratio of the heat exchange unit area to the total heat exchanger area is less than 1 / 6, the heat exchange unit area is too small, resulting in a smaller heat exchanger cavity where the heat exchange unit is located, greater airflow resistance, and inconvenient fan installation, affecting air flow and return from the heat exchanger cavity. Therefore, the minimum area of ​​the heat exchange unit should be greater than or equal to one-sixth of the heat exchanger area. This allows the heat exchange unit to maintain a minimum size, facilitate fan installation, and ensure smooth airflow within the heat exchanger cavity.

[0086] For example, the ratio of the area of ​​one heat exchange portion to the area of ​​the heat exchanger may be 1 / 6, 1 / 5, 2 / 5, 1 / 4, 1 / 3, 1 / 2 or 2 / 3, etc.

[0087] In practical applications, the number of heat exchange parts and the area of ​​each heat exchange part can be set according to the number and size of the compartments.

[0088] Alternatively, as Figure 10 As shown, the heat exchanger assembly further includes a separator 50, which is provided on the heating wire 70 and corresponds to the partition 30, and is used to separate the heating wire 70 into a plurality of heating parts, the number of which is the same as the number of the heat exchange parts and corresponds one to one.

[0089] In the disclosed embodiment, the heating wire 70 is located on one side of the heat exchanger 20 for defrosting the heat exchanger 20. Therefore, a gap exists at the location corresponding to the heating wire 70, so that the cold air or odor of the multiple heat exchange components can be diffused through the location of the heating wire 70. Therefore, a separator 50 is also provided corresponding to the heating wire 70. This prevents the cold air or odor of the multiple heat exchange components from bypassing the heat exchanger 20 and diffusing from the heating wire 70, thereby improving the separation effect between the multiple heat exchange components.

[0090] Optionally, the partition 50 includes a first partition 501 and a second partition 502 , and the second partition 502 is detachably connected to the first partition 501 .

[0091] In the embodiments of the present disclosure, the two parts of the partition 50 are detachably connected, so that the first partition 501 and the second partition 502 are connected and detached, and the partition 50 can be installed without disassembling the entire heating wire 70.

[0092] Optionally, the first partition 501 is inserted into the second partition 502. In this way, the first partition 501 and the second partition 502 are operated, and the convenience of installation and disassembly of the partition 50 is improved.

[0093] Optionally, the first partition 501 is provided with an insertion slot 503 at opposite ends, and the opposite two end portions of the second partition 502 can be inserted into the insertion slot 503, and when the second partition 502 is connected to the first partition 501, the first partition 501 and the second partition 502 are partially overlapped in the thickness direction.

[0094] In the embodiments of the present disclosure, the first partition 501 and the second partition 502 are inserted into the insertion slot 503, so that the first partition 501 and the second partition 502 are connected and detached, and when the second partition 502 is connected to the first partition 501, the first partition 501 and the second partition 502 are partially overlapped in the thickness direction, so that the second partition 502 can be inserted into the insertion slot 503 at the two ends of the first partition 501, and the strength of the first partition 501 and the second partition 502 is improved.

[0095] Optionally, the first partition 501 and the second partition 502 can also be detachably connected by clamping, magnetic attraction or screw connection.

[0096] Optionally, the end portion of the first partition 501 towards the second partition 502 is provided with a first recess, and the end portion of the second partition 502 towards the first partition 501 is provided with a second recess, and when the first partition 501 is connected to the second partition 502, the first recess and the second recess enclose a recess 504, and the heating wire 70 is located in the recess 504.

[0097] In the embodiments of the present disclosure, the first partition 501 and the second partition 502 enclose the recess 504, so that the recess 504 facilitates the passage of the heating wire 70, so as to ensure the length of the heating wire 70, and further ensure the defrosting effect of the entire heat exchanger 20.

[0098] Optionally, the recess 504 is matched with the heating wire 70, that is, the heating wire 70 abuts against the recess 504, so as to avoid the spread of cold or odor from the recess 504 to the adjacent heat exchange part.

[0099] Optionally, the end of the partition 50 away from the heat exchanger 20 is adapted to abut against the inner wall surface of the heat exchanger cavity. In this way, the cold energy transmission on both sides of the partition 50 can be completely isolated, and the cooperation of the partition 50 and the partitioning member 30 can completely isolate the adjacent two heat exchange parts, so that the cold energy on both sides of the two heat exchange parts cannot diffuse to each other.

[0100] Optionally, the partition 50 and the partitioning member 30 are detachably connected or fixedly connected.

[0101] Optionally, when the partition 50 and the partitioning member 30 are detachably connected, the installation and disassembly of the partition 50 and the partitioning member 30 are facilitated.

[0102] Optionally, the end of the partition 50 towards the partitioning member 30 is provided with a connecting plate, and the connecting plate is adapted to abut against the partitioning member 30 to increase the contact area of the partition 50 and the partitioning member 30, thereby improving the connection strength and stability of the partition 50 and the partitioning member 30.

[0103] Optionally, the connecting plate and the partitioning member 30 are detachably connected or fixedly connected.

[0104] Optionally, the connecting plate is connected with both the first partitioning member and the second partitioning member.

[0105] Optionally, as shown in Figure 2 , when the heat exchanger assembly includes an insulation member, the insulation member is located between the partitioning member 30 and the partition 50.
