[0032] Please see Figures 1 to 2 This utility model provides a refrigerant sealing structure 100 for use in an air conditioner 200. The air conditioner 200 includes a heat exchanger 12, which includes a finned portion 16 and a pipe portion 18. The pipe portion 18 is disposed on the end face of the finned portion 16. The refrigerant sealing structure 100 has a receiving cavity 20. The surface of the refrigerant sealing structure 100 facing the heat exchanger 12 has a mounting port 22, which communicates with the receiving cavity 20. One end of the finned portion 16 is embedded in the mounting port 22 to seal the receiving cavity 20 so that the pipe portion 18 is located within the receiving cavity 20.

[0033] Specifically, in Figure 2 In the middle, the pipe section 18 includes a plurality of U-shaped tubes 24, which are the portions of the heat exchange tubes exposed outside the finned section 16. In one embodiment, please refer to... Figure 3 The finned portion 16 includes a heat exchange tube and a plurality of fins 26. The fins 26 are provided with openings 28, and the heat exchange tube passes through the openings 28 on the fins 26 to connect the fins 26 to the heat exchange tube. Optionally, the heat exchanger 12 can be an evaporator.

[0034] In one embodiment, the refrigerant sealing structure 100 is disposed on the bottom side of the U-shaped tube 24, which is the side of the heat exchange tube away from the refrigerant inlet and outlet tubes. Optionally, the pipe section 18 can be welded to the end face of the fin section 16.

[0035] The shape of the mounting opening 22 is adapted to the end shape of the fin portion 16, thereby allowing the fin portion 16 to be more tightly fitted into the mounting opening 22, which to a certain extent improves the sealing effect of the receiving cavity 20. Figure 2 In the fin portion 16, the end shape is arc-shaped, and the mounting port 22 and the refrigerant sealing structure 100 are arc-shaped to match the end shape of the fin portion 16. Optionally, the refrigerant sealing structure 100 is elastic to fit tightly with the fin portion 16.

[0036] During long-term use of the air conditioner 200, refrigerant may leak from the connection between the pipe section 18 and the fin section 16, or from other parts of the pipe section 18. Therefore, by mounting the refrigerant sealing structure 100 on one side of the heat exchanger 12, the fin section 16 can seal the receiving cavity 20 to form a sealed space. When a refrigerant leak occurs, the leaked refrigerant is confined within the sealed receiving cavity 20, preventing refrigerant overflow and facilitating the detection of refrigerant leaks by the refrigerant detection components.

[0037] Alternatively, the refrigerant sealing structure 100 may be detachably mounted on the heat exchanger 12.

[0038] In some embodiments, the fin portion 16 includes fins 26 and a side plate 30, the side plate 30 being connected to the end of the fins 26, the side plate 30 including the end face of the fin portion 16, and the pipe portion 18 being connected to the side plate 30.

[0039] Therefore, the end of the fin 26 can be sealed by the side plate 30 to prevent refrigerant leakage and overflow through the louvers 32 of the fin 26.

[0040] Specifically, please combine Figure 3 The fins 26 are provided with louvers 32, which are spaced apart from the openings 28. The louvers 32 on the fins 26 can increase the surface area of ​​the fins 26, thereby improving the heat transfer efficiency of the evaporator, allowing the evaporator to absorb heat more efficiently and thus improve the cooling effect. The openings 28 allow heat exchange tubes to pass through, and the heat exchange tubes are connected to the fins 26, so that the heat exchange tubes can exchange heat with the air through the fins 26.

[0041] The side plate 30 is provided with a connecting hole 34 aligned with the opening 28, so that the side plate 30 allows the heat exchange tube to pass through the fin 26 to the outside to form a pipe section 18. The side plate 30 is connected to the end of the fin 26, so that it can completely cover the louvers 32 of the fin 26, preventing refrigerant leakage from overflowing through the louvers 32 of the fin 26.

[0042] The side plate 30 is a contoured side plate, the shape of which is adapted to the shape of the fins 26. Optionally, the side plate 30 can be made of hot-dip galvanized steel sheet, and the side plate 30 can be fixed when the high-expansion tube of the evaporator is produced. The side plate 30 is provided with connecting holes 34 along the arc shape of the evaporator, which completely cover the louvers 32 of the fins 26.

[0043] In some embodiments, the refrigerant sealing structure 100 includes a support plate 36 and a sealing gasket 38. The support plate 36 has an installation port 22 on the side facing the fin portion 16 and an assembly port 40 on the side facing away from the fin portion 16. The sealing gasket 38 is assembled at the assembly port 40 to form a receiving cavity 20 together with the support plate 36.

[0044] Therefore, the refrigerant sealing structure 100 can be formed by the support plate 36 and the sealing gasket 38, which can not only play a sealing role, but also support the heat exchanger 12.

[0045] Specifically, the support plate 36 can support the heat exchanger 12, and the heat exchanger 12 with the support plate 36 can be installed on the air conditioner 200 through the support plate 36, thereby avoiding the use of additional installation structures.

[0046] Mounting port 22 and assembly port 40 are respectively located on opposite sides of the support plate 36. The shapes of the support plate 36 and the sealing gasket 38 are adapted to the end shape of the fin portion 16, so that the support plate 36 can better fit with the fin portion 16. The sealing gasket 38 is a contoured sealing gasket, which can better fit with the support plate 36 and improve the sealing performance of the receiving cavity 20 to a certain extent.

[0047] In some embodiments, the support plate 36 is a plastic support plate 36, and / or the sealing gasket 38 is an elastic gasket.

[0048] Therefore, the support plate 36 is easy to manufacture, and the sealing gasket 38 can fit tightly with the support plate 36 to improve the sealing performance of the receiving cavity 20.

[0049] Specifically, in one embodiment, the support plate 36 is a plastic support plate 36 and the sealing gasket 38 is an elastic gasket. In one embodiment, the support plate 36 is a plastic support plate 36, or the sealing gasket 38 is an elastic gasket.

[0050] The support plate 36 is a plastic support plate, which can be manufactured in one piece using injection molding, making it simple, efficient, and low-cost. The plastic support plate 36 can also effectively support the heat exchanger 12.

[0051] The sealing gasket 38 is an elastic gasket, allowing for elastic deformation during assembly with the support plate 36. The elastically deformed gasket 38 tends to recover its original shape, and when constrained by the support plate 36, it can connect more tightly to the support plate 36, thus improving the sealing performance of the receiving cavity 20 to some extent. Optionally, the material of the sealing gasket 38 may include, but is not limited to, rubber or silicone. The sealing gasket 38 may also be a one-piece molded structure.

[0052] In some embodiments, the sealing gasket 38 is connected to the support plate 36 by an interference fit.

[0053] Thus, the sealing gasket 38 and the support plate 36 can be assembled without screws.

[0054] Specifically, the sealing gasket 38 and the support plate 36 are connected by an interference fit. On the one hand, the interference fit allows for a tighter connection between the sealing gasket 38 and the support plate 36. The amount of interference fit can be determined according to actual needs, and this utility model does not impose a specific limitation on it.

[0055] On the other hand, the snap-fit ​​connection method can fix the gasket 38 and the support plate 36 together, preventing the gasket 38 from separating from the support plate 36 when the air conditioner 200 vibrates due to transportation or installation. In summary, the gasket 38 and the support plate 36 can be assembled together without screws, and the gasket 38 and the support member 48 have high manufacturability.

[0056] Optionally, the end of the sealing gasket 38 facing the support plate 36 can be fitted into the assembly port 40 by interference fit, so that the sealing gasket 38 can effectively seal the assembly port 40 and improve the sealing performance of the receiving cavity 20.

[0057] One of the sealing gasket 38 and the support plate 36 is provided with a buckle, and the other is provided with a buckle hole. The buckle is engaged in the buckle hole, thereby fixing the sealing gasket 38 and the support plate 36 by means of buckle.

[0058] Alternatively, in other embodiments, hot melt adhesive can be added to bond the sealing gasket 38 and the support plate 36, or screws can be added to fix and connect the sealing gasket 38 and the support plate 36.

[0059] In some embodiments, the refrigerant sealing structure 100 is a one-piece molded structure.

[0060] This simplifies the assembly process of the refrigerant sealing structure 100 on the heat exchanger 12.

[0061] Specifically, the one-piece molded refrigerant sealing structure 100 can be assembled onto the heat exchanger 12 as a single unit, reducing assembly steps and simplifying the assembly process. In one embodiment, the refrigerant sealing structure 100 can be a molded foam sponge structure, directly assembled onto the pipe section 18 to completely enclose the pipe section 18, thereby achieving a sealing effect. In another embodiment, the refrigerant sealing structure 100 can be an injection-molded part, thus eliminating the need for the sealing gasket 38.

[0062] In some embodiments, the refrigerant sealing structure 100 is provided with a detection through hole 42, which communicates with the receiving cavity 20.

[0063] Therefore, the refrigerant detection function can be achieved by detecting the through hole 42.

[0064] Specifically, the detection through-hole 42 is connected to the receiving cavity 20, and a conduit can be used to guide the refrigerant in the receiving cavity 20 from the detection through-hole 42 to the detection component, thereby enabling refrigerant leakage detection in the pipeline section 18. Please refer to... Figure 4 and Figure 5 In one embodiment, the detection through-hole 42 is located on the upper part of the sealing gasket 38 to facilitate the installation of the conduit. In other embodiments, the detection through-hole 42 may be located on the support plate 36 or at other locations on the sealing gasket 38 to achieve the refrigerant detection function.

[0065] In some embodiments, the refrigerant sealing structure 100 is provided with a mounting part 44, which is adapted to fix the heat exchanger 12 to the motor bracket 52 of the air conditioner 200.

[0066] This reduces the need for installation structures and facilitates the assembly of heat exchanger 12.

[0067] Specifically, please combine Figure 2 In one embodiment, the mounting part 44 is provided on the support plate 36. The mounting part 44 has mounting holes 46, through which fasteners can pass and connect to the motor bracket 52 of the air conditioner 200, thereby fixing the heat exchanger 12 to the motor bracket 52 of the air conditioner 200. Fasteners include, but are not limited to, screws, pins, rivets, etc. Optionally, the mounting part 44 and the support plate 36 are integrally formed, thereby increasing the connection strength between the mounting part 44 and the support plate 36, and ensuring the stable installation of the heat exchanger 12 to a certain extent.

[0068] In one embodiment, one of the mounting part 44 and the motor bracket 52 is provided with a buckle, and the other is provided with a locking hole. The buckle is engaged in the locking hole, so that the heat exchanger 12 can be assembled onto the motor bracket 52 of the air conditioner 200.

[0069] Optionally, air conditioner 200 is an indoor air conditioner, and motor bracket 52 is used to install the motor of the indoor fan.

[0070] In some embodiments, a support member 48 is provided on the inner wall of the receiving cavity 20, and the support member 48 supports and limits the pipe section 18.

[0071] This can improve the stability of the pipe section 18.

[0072] Specifically, please combine Figure 2 The duct section 18 is exposed outside the fin section 16 and located in the receiving cavity 20. If the air conditioner 200 vibrates due to factors such as transportation or installation, the duct section 18 may also vibrate, which may easily lead to deformation of the duct section 18 or separation from the side plate 30.

[0073] The support member 48 can support and limit the pipe section 18 within the receiving cavity 20, thereby reducing the vibration of the pipe section 18 to a certain extent and improving the stability of the pipe section 18.

[0074] exist Figure 2 In this configuration, the support member 48 is disposed within the receiving cavity 20 portion of the support plate 36. The support member 48 can connect to the inner wall of the receiving cavity 20 and also acts as a reinforcing rib, improving the structural strength of the support plate 36 and further enhancing the installation stability of the heat exchanger 12.

[0075] In some implementations, please refer to Figure 6 The support member 48 is provided with a receiving space 54, the shape of which is adapted to the shape of the pipe section 18.

[0076] Therefore, the support member 48 provides high stability in limiting the position of the pipe section 18.

[0077] Specifically, in Figure 6 In the middle, the pipe section 18 is U-shaped, and the shape of the accommodating space 54 is adapted to the external shape of the U-shape. Therefore, when the pipe section 18 is assembled in the accommodating space 54, the accommodating space 54 fits the pipe section 18 well, reducing the adverse effects of vibration on the pipe section 18 during the use and transportation of the air conditioner 200. This can reduce or avoid deformation of the pipe section 18 and, to a certain extent, ensure the service life of the heat exchanger 12.

[0078] In some implementations, please refer to Figure 6 The refrigerant sealing structure 100 includes a reinforcing rib 56, which connects the support member 48 to the side wall of the receiving cavity 20.

[0079] This can improve the strength of the refrigerant sealing structure.

[0080] Specifically, in one embodiment, the support member 48 is used to support and limit the pipe section 18, and the support member 48 is provided with an accommodating space 54. The reinforcing rib 56 can connect the support member 48 to the side wall of the accommodating cavity 20, thereby strengthening the support member 48 and effectively supporting and limiting the pipe section 18. During the use of the air conditioner 200, the reinforcing rib 56 can prevent the support member from deforming or cracking due to the force of the pipe section 18, and to a certain extent improve the strength of the refrigerant sealing structure 100.

[0081] Please combine Figure 1 An air conditioner 200 provided by this utility model includes the refrigerant sealing structure 100 of any of the above embodiments.

[0082] In the aforementioned air conditioner 200, a refrigerant sealing structure 100 is mounted on one side of the heat exchanger 12, and the fin portion 16 can seal the receiving cavity 20 to form a sealed space. When a refrigerant leak occurs, the leaked refrigerant is confined within the sealed receiving cavity 20. This prevents refrigerant from overflowing and also facilitates the detection of refrigerant leaks by the refrigerant detection component.

[0083] Specifically, the air conditioner 200 may include an indoor unit, and the refrigerant sealing structure 100 may be applied to the indoor unit. Please refer to... Figure 1 The air conditioner 200 also includes a drip tray 50, which is located below the refrigerant sealing structure 100. The drip tray 50 can collect the condensate dripping from the heat exchanger 12, preventing the condensate from flowing onto the electrical components of the air conditioner 200 and causing accidents such as short circuits in the air conditioner 200.

[0084] In some embodiments, the air conditioner 200 includes a heat exchanger 12 and a motor bracket 52, the heat exchanger 12 being fixed to the motor bracket 52 by a refrigerant sealing structure 100.

[0085] Therefore, the heat exchanger 12 can be fixed on the motor bracket 52 using the refrigerant sealing structure 100.

[0086] Specifically, please combine Figure 2 The refrigerant sealing structure 100 includes a support plate 36 and a sealing gasket 38, with a mounting part 44 disposed on the support plate 36. The mounting part 44 has mounting holes 46, through which fasteners can pass and connect to the motor bracket 52, thereby fixing the heat exchanger 12 to the motor bracket 52. Fasteners include, but are not limited to, screws, pins, and rivets. Optionally, the mounting part 44 and the support plate 36 are integrally formed, thereby increasing the connection strength between the mounting part 44 and the support plate 36, and to a certain extent ensuring the stable installation of the heat exchanger 12.

[0087] Optionally, the air conditioner 200 also includes a chassis 58, on which a motor bracket 52 is mounted. Optionally, the air conditioner 200 is an indoor air conditioner, and the motor bracket 52 is used to mount the motor of the indoor fan.

[0088] In one embodiment, one of the mounting part 44 and the motor bracket 52 is provided with a buckle, and the other is provided with a locking hole. The buckle is engaged in the locking hole, so that the heat exchanger 12 can be assembled onto the motor bracket 52 of the air conditioner 200.

[0089] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with an embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0090] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
