To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention.

[0029] Please refer to Figures 1 to 8 An air conditioner 100 provided by an embodiment of the present invention includes a heat exchanger 12 and a refrigerant sealing structure 14. The refrigerant sealing structure 14 includes a sealing box 16, which has a receiving cavity 18 and an exhaust port 20. The exhaust port 20 is connected to the receiving cavity 18. The heat exchanger 12 has two phase-separated ends. The sealing box 16 is disposed on the heat exchanger 12 and covers at least one of the phase-separated ends of the heat exchanger 12. At least one of the phase-separated ends of the heat exchanger 12 is located in the receiving cavity 18. The exhaust port 20 is used to connect with the outdoor environment.

[0030] In the aforementioned air conditioner 100, the sealing box 16 covers at least one of the two phase-separated ends of the heat exchanger 12. At least one of the two phase-separated ends of the heat exchanger 12 is located in the receiving cavity 18, and the exhaust port 20 is connected to the outside of the air conditioner 100. Therefore, when refrigerant leaks at least one of the two phase-separated ends of the heat exchanger 12, the leaked refrigerant can be collected in the receiving cavity 18 and discharged to the outdoor environment through the exhaust port 20, thereby reducing the concentration of leaked refrigerant and avoiding refrigerant combustion and explosion accidents to a certain extent.

[0031] Specifically, air conditioner 100 includes, but is not limited to, split-type air conditioners and integrated air conditioners. Split-type air conditioners may include an indoor unit and an outdoor unit, while integrated air conditioners combine the functions of an indoor unit and an outdoor unit into one unit. Integrated air conditioners may be installed on the roof or on the exterior wall of a building. Figures 1 to 3 The air conditioner 100 in the embodiment shown is an integrated air conditioner. The air conditioner 100 includes a housing 22, which has two accommodating spaces. Components related to the function of the indoor unit can be housed in one accommodating space, and components related to the function of the outdoor unit can be housed in the other accommodating space. These components can be connected by pipes and wires.

[0032] The heat exchanger 12 can be a condenser and / or an evaporator. The heat exchanger 12 includes two phase-separated ends, which can be non-adjacent ends or ends facing away from each other in one direction. Optionally, one end is a U-shaped end 24, and the other end is a pipe end 26. The U-shaped end 24 redirects the refrigerant within the heat exchanger 12 to form a circulating flow path. The pipe end 26 can be connected to a refrigerant inlet pipe and a refrigerant outlet pipe, thereby enabling the refrigerant to flow in and out, allowing heat exchange between the refrigerant and the heat exchanger 12. Thus, the heat exchanger 12 can perform operations such as cooling, heating, and dehumidifying the air.

[0033] In related technologies, refrigerant leaks may occur at both ends of the heat exchanger. Therefore, in this embodiment of the invention, the air conditioner 100 includes a refrigerant sealing structure 14, which includes a sealing box 16. The sealing box 16 is disposed on the heat exchanger 12 and covers at least one of the separated ends of the heat exchanger 12. At least one of the separated ends of the heat exchanger 12 is located in a receiving cavity 18, and the exhaust port 20 is connected to the outdoor environment. Thus, when refrigerant leaks at least one of the ends of the heat exchanger 12, the leaked refrigerant can be collected in the receiving cavity 18 and discharged into the outdoor environment through the exhaust port 20, thereby preventing an accident of combustion and explosion of flammable refrigerant.

[0034] Optionally, when the air conditioner 100 is installed in an outdoor environment, such as a rooftop air conditioner or an exterior wall air conditioner, the exhaust port 20 can directly discharge the leaked refrigerant to the outdoor environment. When the air conditioner 100 is installed in an indoor environment, such as an indoor unit, the exhaust port 20 can be connected by a pipe that passes through the wall, thereby discharging the leaked refrigerant to the outdoor environment.

[0035] In one embodiment, both ends of the heat exchanger 12 that are separated from each other are covered with sealing boxes 16, that is, one sealing box 16 covers the pipe end 26 and the other sealing box 16 covers the U-shaped end 24. In one embodiment, one end of the heat exchanger 12 that is separated from each other is covered with a sealing box 16, for example, the sealing box 16 can cover the pipe end 26 or the sealing box 16 can cover the U-shaped end 24.

[0036] The sealing box 16 may be made of materials including, but not limited to, metal and plastic. Optionally, the sealing box 16 may be manufactured using a one-piece molding process, thereby improving sealing performance.

[0037] In some implementations, please refer to Figure 2 , Figure 3 as well as Figures 6 to 8 The heat exchanger 12 has two phase-separated ends, including U-shaped ends 24, and the sealing box 16 covers the U-shaped ends 24.

[0038] Therefore, in the event of a refrigerant leak at the U-shaped end 24, the leaked refrigerant can be collected and discharged into the outdoor environment.

[0039] Specifically, during the use of the air conditioner 100, the U-shaped end 24 is a location prone to refrigerant leakage. In the illustrated embodiment, the sealing box 16 covers the U-shaped end 24, which is located within the receiving cavity 18. When refrigerant leakage occurs at the U-shaped end 24, the leaked refrigerant can be collected within the receiving cavity 18 and discharged to the outdoor environment through the exhaust port 20, thereby preventing refrigerant from accumulating inside the casing 22 or in the indoor environment and causing a combustion or explosion accident.

[0040] In some implementations, please refer to Figure 2 , Figure 3 as well as Figures 6 to 8 The heat exchanger 12 includes a body 28 and a heat exchange tube 30. The heat exchange tube 30 passes through the body 28 and extends out of the two ends of the body 28. The refrigerant sealing structure 14 includes a sealing plate 32. The sealing plate 32 has a through hole 34. The heat exchange tube 30 passes through the through hole 34 and is tightly connected to the hole wall of the through hole 34. The sealing plate 32 is located at at least one end of the body 28. The sealing box 16 has an opening 36 that communicates with the receiving cavity 18. The sealing plate 32 is located at the opening 36 to seal the receiving cavity 18.

[0041] Therefore, the sealing plate 32 can prevent leaked refrigerant from spreading from the containment cavity 18 toward the body 28 of the heat exchanger 12 to a certain extent.

[0042] Specifically, the body 28 may include a plurality of fins arranged in sequence. Heat exchange tubes 30 pass through the fins and extend beyond both ends of the body 28. The two ends of the heat exchange tubes 30 extending beyond the body 28 can respectively form the pipe end 26 and the U-shaped end 24 of the heat exchanger 12. The sealing plate 32 has a through hole 34. The heat exchange tubes 30 pass through the through hole 34 and are tightly connected to the wall of the through hole 34. The sealing plate 32 is located at the opening 36 to seal the receiving cavity 18, thereby allowing the receiving cavity 18 to form a relatively sealed space. The sealing plate 32 is located at at least one end of the body 28. Figure 2 and Figure 8 In the middle, the sealing box 16 covers the U-shaped end 24 of the heat exchanger 12, and correspondingly, the sealing plate 32 is provided at one end of the body 28 connected to the U-shaped end 24.

[0043] Since the heat exchange tube 30 is tightly connected to the hole wall of the through hole 34, the sealing plate 32 can prevent the leaked refrigerant in the containment cavity 18 from spreading towards the body 28, and to a certain extent prevent the leaked refrigerant from seeping into the box 22 from the gap between the heat exchange tube 30 and the sealing plate 32 and the window gap of the fins.

[0044] The openings in the fins increase the surface area of ​​the fins, thereby improving the heat transfer efficiency of the heat exchanger 12. This allows the heat exchanger 12 to exchange heat more efficiently, thus improving the cooling or heating effect. The fins have openings that allow the heat exchange tubes 30 to pass through. The heat exchange tubes 30 are connected to the fins, allowing the heat exchange tubes 30 to exchange heat with the air through the fins.

[0045] Optionally, the sealing plate 32 is a contoured sealing plate, the shape of which is adapted to the shape of the fins. The material of the sealing plate 32 includes, but is not limited to, hot-dip galvanized steel. When the heat exchanger 12 is manufactured with high-expansion tubes, the heat exchange tubes 30 can be made to fit tightly with the through holes 34 of the sealing plate 32, thereby preventing refrigerant leakage from seeping into the housing 22 through the gaps between the heat exchange tubes 30 and the sealing plate 32, as well as the openings in the fins.

[0046] The heat exchange tube 30 includes, but is not limited to, copper tubes, and the fins include, but are not limited to, copper fins.

[0047] In some implementations, please refer to Figure 7 and Figure 8The body 28 includes a first end 38, the end face of the first end 38 is stepped, the end face of the first end 38 includes a first surface 40 and a second surface 42 that are connected to each other, the heat exchange tube 30 passes through the second surface 42, the sealing plate 32 includes a first plate 44 and a second plate 46 that are connected to each other, the second plate 46 has a through hole 34, the second plate 46 is disposed on the second surface 42, and the first plate 44 is disposed on the first surface 40.

[0048] Therefore, it can, to a certain extent, prevent the refrigerant leaking from the gaps between the fins into the housing 22 when the body 28 with a stepped end face leaks, and prevent the leaked refrigerant from seeping into the housing 22 from the gap between the heat exchange tube 30 and the sealing plate 32 and the opening gap of the fins.

[0049] Specifically, the body 28 includes a plurality of fins arranged in sequence, with gaps formed between adjacent fins. Figures 6 to 8 In the illustrated embodiment, the heat exchanger 12 is generally L-shaped, and the body 28 includes a first end 38 and a second end 47. In one embodiment, the first end 38 is one end of the body 28 connected to the U-shaped end 24, and the second end 47 is the other end of the body 28 connected to the pipe end 26. The end face of the second end 47 is approximately planar, and the end face of the first end 38 is segmented. It can be understood that in other embodiments, the heat exchanger is generally L-shaped, and the end faces of the two separated ends of the body can also be approximately planar.

[0050] The heat exchange tube 30 passes through the second surface 42, meaning that the heat exchange tube 30 exits from the second surface 42 of the end face of the first end 38 and passes through the through hole 34 on the second plate 46, which is located on the second surface 42. The heat exchange tube 30 is tightly connected to the wall of the through hole 34, so that the refrigerant in the receiving cavity 18 will not or cannot easily diffuse towards the second surface 42 of the body 28, thereby preventing the refrigerant from seeping into the housing 22 from the gap between the heat exchange tube 30 and the sealing plate 32 and the opening gap of the fins.

[0051] The first plate 44 is connected to the second plate 46. The first plate 44 is located on the first surface 40 and seals the side of the misaligned body 28, so that the refrigerant in the receiving cavity 18 will not or will not easily diffuse toward the first surface 40 of the body 28, thereby preventing the refrigerant from entering the box 22 from the gap between the fins to a certain extent.

[0052] Optionally, in one embodiment, the first end 38 may be one end of the body 28 connected to the pipe end 26, and the second end 47 may be the other end of the body 28 connected to the U-shaped end 24.

[0053] In some implementations, please refer to Figure 8 Along the thickness direction D of the body 28, the second surface 42 and the first surface 40 are alternately arranged, and the first plate 44 connects two adjacent second plates 46.

[0054] This can further improve the sealing performance of the sealing plate 32.

[0055] Specifically, in Figure 7 and Figure 8 In the illustrated embodiment, there are four second surfaces 42 and three first surfaces 40. Along the thickness direction D of the body 28, the four second surfaces 42 and three first surfaces 40 are alternately arranged to form a stepped end face of the first end 38. The first surface 40 connects to two adjacent second surfaces 42. Correspondingly, the first plate 44 connects to two adjacent second plates 46, thereby sealing the connection between the first plate 44 and the second plate 46 and further improving the sealing performance of the sealing plate 32.

[0056] The first plate 44 and the second plate 46 can be connected by means including but not limited to welding, screws, rivets, etc. It is understood that the present invention does not specifically limit the number of the second surface 42 and the first surface 40.

[0057] In some implementations, please refer to Figures 3 to 5 as well as Figure 7 and Figure 8 The outer side of the sealing plate 32 is provided with a fixing part 48, and the sealing box 16 is fixedly connected to the sealing plate 32 through the fixing part 48.

[0058] This allows for easy connection between the sealing plate 32 and the sealing box 16.

[0059] Specifically, in Figures 4 to 5 In the embodiment shown, the sealing plate 32 is generally flat, and a fixing part 48 is provided on both outer sides of the sealing plate 32.

[0060] exist Figures 7 to 8 In the embodiment shown, the sealing plate 32 includes a first plate 44 and a second plate 46 connected to each other. Along the thickness direction D of the body 28, the outermost second plate 46 is a third plate 50. A fixing part 48 is provided on the outer side of the third plate 50, and the outer side of the third plate 50 is the side of the third plate 50 away from the first plate 44. The sealing box 16 is fixedly connected to the sealing plate 32 through the fixing part 48. Figure 8 In this configuration, there are two third plates 50. Two fixing parts 48 extend into the receiving cavity 18 and connect to the side wall of the receiving cavity 18, thereby improving the sealing and stability of the connection between the sealing plate 32 and the sealing box 16. The fixing parts 48 and the sealing box 16 can be connected by means including but not limited to welding, screws, and rivets.

[0061] After the sealing box 16 and the sealing plate 32 are assembled, a relatively sealed cavity 18 is formed for the heat exchanger 12 which is prone to leakage.

[0062] In some implementations, please refer to Figure 4 , Figure 5 and Figure 8 The sealing plate 32 has an annular joint 52 protruding along the edge of the through hole 34, and the heat exchange tube 30 passes through the joint 52 and is tightly connected to the joint 52.

[0063] This increases the area of ​​tight contact between the sealing plate 32 and the heat exchange tube 30, which helps to improve the sealing effect between the sealing plate 32 and the heat exchange tube 30.

[0064] Specifically, the joint 52 is arranged in a ring shape circumferentially along the edge of the through hole 34. Without increasing the thickness of the sealing plate 32, the joint 52 effectively increases the thickness of the hole wall of the through hole 34. The heat exchange tube 30 passes through the through hole and the joint 52, and the heat exchange tube 30 is tightly connected to the joint 52, which increases the tight contact area between the heat exchange tube 30 and the sealing plate 32, thus improving the sealing effect between the sealing plate 32 and the heat exchange tube 30.

[0065] exist Figures 7 to 8 In the embodiment shown, the sealing plate 32 includes a first plate 44 and a second plate 46 connected to each other. The second plate 46 is provided with a through hole 34, and the joint portion 52 is provided on the second plate 46.

[0066] Optionally, Figures 3 to 5 When manufacturing the sealing plate 32 shown, it can be integrally manufactured using a stretch forming process to obtain a sealing plate 32 having components such as a fixing part 48 and a connecting part 52.

[0067] Optionally, Figures 7 to 8 When manufacturing the sealing plate 32 shown, the first plate 44 and the second plate 46 can be integrally manufactured using a stretch forming process, thereby obtaining the second plate 46 having components such as the fixing part 48 and the connecting part 52, and the first plate 44 having the corresponding structure. Then the first plate 44 and the second plate 46 can be assembled together.

[0068] Optionally, Figures 7 to 8 When manufacturing the sealing plate 32 shown, the sealing plate 32 having the first plate 44 and the second plate 46 and the corresponding structure can be integrally manufactured using a stretch forming process.

[0069] The joint 52 can be provided on the surface of the sealing plate 32 facing the body 28 of the heat exchanger 12, or on the surface of the sealing plate 32 away from the body 28 of the heat exchanger 12, or on both the surface of the sealing plate 32 facing the body 28 of the heat exchanger 12 and the surface away from the body 28 of the heat exchanger 12.

[0070] Alternatively, in one embodiment, the joint 52 may be a structure formed by the flange on the sealing plate 32.

[0071] In some implementations, please refer to Figure 3 and Figure 8 The joint 52 is embedded in the body 28.

[0072] This allows for a reduction in the size of the heat exchanger 12, which is beneficial for achieving a compact air conditioner 100.

[0073] Specifically, with Figure 8 The illustrated implementation is given as an example. Figure 8 In the illustrated embodiment, the connecting portion 52 protrudes from the surface of the sealing plate 32 facing the body 28 of the heat exchanger 12. The connecting portion 52 is embedded within the body 28, which can reduce the distance between the sealing plate 32 and the body 28 to a certain extent, thereby reducing the size of the heat exchanger 12 and facilitating the realization of a compact air conditioner 100. Optionally, the connecting portion 52 can be completely embedded within the body 28 so that the surface of the sealing plate 32 facing the body 28 of the heat exchanger 12 fits against the end face of the body 28, thereby further reducing the size of the heat exchanger 12.

[0074] In some implementations, please refer to Figure 2 , Figure 3 as well as Figures 6 to 8 The air conditioner 100 includes a water receiving tray 54, which has a water receiving groove 56. The bottom of the heat exchanger 12 is located in the water receiving groove 56. The side of the sealing box 16 facing the bottom of the water receiving groove 56 is an open side 58, and the bottom of the water receiving groove 56 seals the open side 58.

[0075] Therefore, the bottom surface of the water receiving tank 56 can be used to seal the opening side 58 of the sealing box 16.

[0076] Specifically, the bottom of the heat exchanger 12 is located in the water receiving tank 56. When condensate appears on the heat exchanger 12, the condensate can slide from the heat exchanger 12 into the water receiving tank 56. The water receiving tank 56 collects the condensate and can guide it to the desired location, which to a certain extent avoids the condensate from flowing onto electrical components and metal components, thus preventing short circuits and corrosion.

[0077] exist Figures 6 to 8 In the middle, the side of the sealing box 16 facing the bottom of the water tank 56 is the lower side of the sealing box 16, and the lower side of the sealing box 16 is the opening side 58.

[0078] Optionally, during assembly, the refrigerant sealing structure 14 can be assembled with the heat exchanger 12, and then the bottom of the heat exchanger 12 with the refrigerant sealing structure 14 is inserted into the water receiving tank 56, so that the opening side 58 of the sealing box 16 is in contact with the bottom surface of the water receiving tank 56, thereby using the bottom surface of the water receiving tank 56 to seal the opening side 58, so that the receiving cavity 18 forms a relatively sealed space.

[0079] Alternatively, in one embodiment, the side of the sealing box 16 facing the bottom of the water tank 56 may be a closed side.

[0080] In some implementations, please refer to Figure 2 The vent 20 is located near the bottom of the sealing box 16 and above the water receiving tray 54.

[0081] This, to some extent, accelerates the discharge of leaked refrigerant from exhaust port 20 into the outdoor environment.

[0082] Specifically, refrigerant has a higher density than air. Therefore, when refrigerant leaks, it tends to accumulate at the bottom of the receiving cavity 18. The vent 20 is located near the bottom of the sealing box 16 and above the drip tray 54. On the one hand, the leaked refrigerant accumulated at the bottom of the receiving cavity 18 can be discharged to the outdoor environment more quickly through the vent 20. On the other hand, the vent 20 being located above the drip tray 54 can prevent the vent 20 from being blocked by the drip tray 56, thus avoiding the inability to discharge the leaked refrigerant in a timely manner. This is especially important when the vent 20 is located inside the drip tray 56, as the drip tray 56 may be submerged by condensate water, preventing the timely discharge of the leaked refrigerant.
