Description

Technical Field

[0001] This utility model relates to the technical field of fixing heat exchangers in air conditioners, and more particularly to a fixing device for a heat exchanger and an air conditioner formed therefrom. Background Technology

[0002] The condenser is a core component of the outdoor unit of an air conditioner, primarily responsible for heat dissipation, refrigerant condensation, and maintaining the refrigeration cycle. Condenser components are typically composed of copper tubes and aluminum foil fins. When the condenser is installed in the air conditioner, its left side is connected and fixed to the left side panel of the air conditioner panel via a support plate, its middle section is clamped by a motor bracket, and its right side is connected and fixed to the right side panel of the air conditioner panel via the right side panel of the condenser. This forms a three-section fixing structure (left, middle, and right) to secure the condenser.

[0003] Because condensers are typically around 50cm high, 80cm long, and 4cm wide, their overall area is relatively large, and there are many pipes on the right side. During transportation and handling, the condenser components are subject to bumps and external forces. Due to their weight and the inadequate fixing structure, they can shift, especially if the pipes on the right side collide with surrounding parts, causing damage to the copper pipes and fins, thus affecting the overall performance of the machine. Utility Model Content

[0004] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide a fixing device for a heat exchanger. The fixing plate and the heat exchanger are fixed together in the panel by a connecting plate. Even if the panel deforms and collapses, the fixing plate and the connecting plate can still support the panel and prevent the panel from directly contacting the heat exchanger, thus avoiding damage to the fins and copper tubes in the heat exchanger.

[0005] A fixing device for a heat exchanger is used to fix the side and panel of the heat exchanger, wherein the side of the heat exchanger is provided with fins and copper tubes; it includes a fixing plate and a connecting plate that are fixed to each other.

[0006] The fixing plate is fixedly connected to the side of the heat exchanger; the fixing plate is provided with a covering through hole, which is used to cover the copper tube in the side of the heat exchanger;

[0007] The connecting plate is provided with a connecting through hole, and the connecting plate and the panel are fixed by fasteners cooperating with the connecting through hole.

[0008] In this application, the sides of the fixing plate and the heat exchanger overlap, increasing the contact area between them and improving the stability of the fixing. At the same time, the fixing plate covers the copper tubes on the side of the heat exchanger, ensuring that the copper tubes are protected even if the heat exchanger shifts position. The fixing plate and the heat exchanger are fixed together in the panel by the connecting plate. Even if the panel deforms and collapses, the fixing plate and the connecting plate can still support the panel and prevent the panel from directly contacting the heat exchanger, which would cause damage to the fins and copper tubes in the heat exchanger.

[0009] In a preferred embodiment of this invention, the covering through hole is a through hole with a flanged structure, and the flange height of the covering through hole is 1.0-2.0 mm.

[0010] The flange in the cover hole refers to the structure that flanges from the center of the cover hole to the outside, i.e. towards the outside of the cover hole, so that a smooth surface is formed at the inner diameter of the cover hole. This prevents the copper tube from being scratched by the edge of the cover hole when it passes through the cover hole. Once the surface of the copper tube is damaged, it will crack and leak due to the stress of the system during the long-term operation of the heat exchanger.

[0011] In a preferred embodiment of this utility model, the fixing plate has M first fastening areas on its side away from the connecting plate. The M first fastening areas are distributed at intervals in the fixing plate, and the first fastening areas and the fixing plate are located in the same plane; M is an integer greater than 0.

[0012] To achieve the fixation of the fixing plate and the side of the heat exchanger, simply using the cover hole and the snap-fit ​​of the copper pipe is insufficient. This application also provides a first fastening area on the side of the fixing plate away from the connecting plate. Specifically, the first fastening area can be a protruding structure relative to the fixing plate, and the first fastening area and the fixing plate are located in the same plane, both of which can fit and abut against the side of the heat exchanger. The first fastening area is used to fix the side of the heat exchanger, and specifically, the first fastening area and the side of the heat exchanger can be fixed by fasteners, thereby achieving a stable connection between the fixing plate and the side of the heat exchanger.

[0013] In a preferred embodiment of this invention, a first fastening through hole is provided at the center of the first fastening area, and an arc transition portion is provided at the edge of the first fastening area; the number of the first fastening areas is three.

[0014] The first fastening through hole can specifically be a screw hole, and the diameter of the first fastening through hole is the same as that of the screw hole on the side of the heat exchanger. The screw passes through the first fastening through hole and the screw hole on the side of the heat exchanger in sequence to achieve fastening between the fixing plate and the side of the heat exchanger. In this application, the first fastening through hole is specifically as follows: Figure 1As shown, the structure features a protruding ear-like shape. The first fastening through-hole is positioned at the center of the first fastening area, ensuring uniform force distribution within the area. Simultaneously, the edges of the first fastening area are provided with rounded transition sections to prevent damage to the copper tubes during assembly with the heat exchanger side. Specifically, there are three first fastening areas, distributed sequentially along the height of the heat exchanger, forming fastening points at the top, middle, and bottom, further ensuring a secure fixation.

[0015] In a preferred embodiment of this invention, the connecting plate has N second fastening areas on its side away from the fixing plate. The N second fastening areas are distributed at intervals in the connecting plate, and the second fastening areas are located in the same plane as the connecting plate; N is an integer greater than 0.

[0016] The connecting plate is used to fix the panel. If the connecting plate is too wide, it will increase the weight of the fixing device and the heat exchanger; if the connecting plate is too narrow, the connection with the panel will be unstable. The width of the connecting plate refers to the direction perpendicular to the plane of the fixing plate. This application sets the width of the connecting plate within the range of 2.5-3.5mm, and provides a second fastening area on the side of the connecting plate away from the fixing plate. The location of the second fastening area is where the connecting plate and the panel are fastened. This second fastening area achieves the fixation of the connecting plate and the panel, and also compensates for the narrow fastening position caused by an excessively narrow connecting plate.

[0017] In a preferred embodiment of this utility model, the panel includes a side panel and a bottom panel, and the number of the second fastening areas is four, wherein three of the second fastening areas are fixed in the side panel by fasteners, and the other second fastening area is fixed in the bottom panel by fasteners.

[0018] When fixing the heat exchanger, its sides are typically secured to both the side panel and the bottom panel simultaneously. Four second fastening areas are distributed sequentially along the height of the connecting plate, which is the same height as the heat exchanger and is significantly taller than its width. The upper three second fastening areas are used to fasten to the side panel, and are respectively located at the top, middle, and bottom of the side panel. The lowermost second fastening area is used to fasten to the bottom panel. The connecting plate enables simultaneous connection of the heat exchanger's sides to both the side and bottom panels.

[0019] In a preferred embodiment of this invention, the connecting plate further includes a connecting region located between the second fastening region and the fixing plate; the connecting plate is provided with a connecting through hole located in both the second fastening region and the connecting region.

[0020] The connecting area in the connecting plate determines the overall strength of the connecting plate, and the second fastening area is as follows: Figure 2 The protruding ear-shaped structure shown has the connecting through hole part located in the connecting area and part located in the second fastening area, so that the fastener is located in the center of the connecting plate, ensuring that the connecting plate is subjected to uniform force in the width direction.

[0021] In a preferred embodiment of this utility model, the size of the connecting area is 2.5-3.5mm in the first direction; the first direction refers to the direction from the second fastening area to the connecting area in the plane perpendicular to the fixing plate.

[0022] In the first direction, the dimensions of the connection area are 2.5-3.5 mm, meaning the width of the connection area is approximately 3 mm, and the height of the connection area matches the height of the heat exchanger. This width range ensures that the connection plate has sufficient strength while also ensuring that the weight of the fixing device remains within acceptable limits.

[0023] In a preferred embodiment of this invention, the top and bottom of the fixing plate are provided with clearance notches, and the clearance notches are provided with arc-shaped corners.

[0024] The top and bottom of the fixing plate refer to the area above and below it in the height direction, while the first fastening area is located in the width direction of the fixing plate. The clearance notch can be a U-shaped clearance structure, which can make way for the copper tubes at the top and bottom of the heat exchanger; at the same time, the rounded corners can prevent the edges of the fixing plate from being too sharp and causing damage to the copper tubes during assembly.

[0025] The second objective of this application is to provide an air conditioner, including a mounting device for a heat exchanger as described above.

[0026] The condenser is fixed inside the air conditioner casing by the fixing device. Even if the air conditioner casing is subjected to external force during transportation or warehouse stacking, or if the air conditioner casing is deformed and collapsed, the fixing plate and connecting plate can support the air conditioner casing and will not damage the fins and copper tubes on the top of the condenser.

[0027] The beneficial effects of this utility model are as follows:

[0028] This utility model provides a fixing device for securing the side and panel of a heat exchanger. The fixing device includes a fixing plate and a connecting plate that are fixed to each other. The fixing plate is used to fix the side of the heat exchanger and has a covering through hole for covering the copper tubes in the side of the heat exchanger. The connecting plate has a connecting through hole, and the connecting plate and the panel are fixed together by fasteners engaging with the connecting through hole. In this application, the fixing plate and the side of the heat exchanger overlap, increasing the contact area between them and improving the stability of the fixation. At the same time, the fixing plate covers the copper tubes in the side of the heat exchanger, ensuring protection for the copper tubes even if the heat exchanger shifts position. The fixing plate and the heat exchanger are fixed together in the panel by the connecting plate. Even if the panel deforms and collapses, the fixing plate and the connecting plate can support the panel, preventing the panel from directly contacting the heat exchanger and causing damage to the fins and copper tubes in the heat exchanger.

[0029] This application also provides an air conditioner, including a fixing device for fixing a heat exchanger as described above. The fixing device fixes the condenser inside the air conditioner casing. Even if the air conditioner casing is subjected to external force during transportation or warehouse stacking, or if the air conditioner casing is deformed and collapsed, the fixing plate and connecting plate can support the air conditioner casing and will not damage the fins and copper tubes on the top of the condenser.

[0040] Example 1

[0041] like Figures 1-5 As shown, this application provides a fixing device for a heat exchanger, used to fix the side and panel of the heat exchanger. The side of the heat exchanger is provided with fins and copper tubes 34; it includes a fixing plate 11 and a connecting plate 21 that are fixed to each other.

[0042] The fixing plate 11 is fixedly connected to the side of the heat exchanger; the fixing plate 11 is provided with a covering through hole 113, which is used to cover the copper tube 34 in the side of the heat exchanger;

[0043] The connecting plate 21 is provided with a connecting through hole 213, and the connecting plate 21 and the panel are fixed by the cooperation of fasteners with the connecting through hole 213.

[0044] In this application, the heat exchanger can be either a condenser 33 or an evaporator, both of which include a finned and copper tube 34 structure. When the evaporator or condenser 33 is installed in the air conditioning unit, it needs to be fixed to the air conditioning panel by a fixing device to ensure the structural stability of the evaporator or condenser 33.

[0045] The copper tubes 34 in the heat exchanger are concentrated on one side, where the fins and copper tubes 34 are welded together. The fixing device in this application is for fixing this side of the heat exchanger to the air conditioner panel. As for the fixing of other sides of the heat exchanger, they can be fixed by existing structures such as brackets.

[0046] In this application, "panel" refers to the outer casing of an air conditioner or other load-bearing panels in an air conditioner, i.e., the plates used to fix the heat exchanger during the assembly process.

[0047] In this application, the fixing plate 11 and the connecting plate 21 can be set vertically or be bent at any angle. The specific angle needs to be set according to the positional relationship between the heat exchanger and the panel. In actual operation, the heat exchanger is a cuboid structure, the air conditioner casing is also a cuboid structure, and the panel is the air conditioner casing. In this case, the fixing plate 11 and the connecting plate 21 can be set vertically to fix the side of the heat exchanger inside the air conditioner casing.

[0048] In this application, the size of the fixing plate 11 can be substantially the same as the side of the heat exchanger, forming a complete cover and protection for the copper tube 34 on the side of the heat exchanger. Alternatively, the fixing plate 11 can be configured to fit only the edge of the side of the heat exchanger, forming a cover at the edge position of the side of the heat exchanger.

[0049] This utility model provides a fixing device for fixing the side and panel of a heat exchanger. The fixing device includes a fixing plate 11 and a connecting plate 21 that are fixed to each other. The fixing plate 11 is used to fix the side of the heat exchanger and has a covering through hole 113 for covering the copper tube 34 in the side of the heat exchanger. The connecting plate 21 has a connecting through hole 213, and the connecting plate 21 and the panel are fixed by fasteners cooperating with the connecting through hole 213. In this application, the fixing plate 11 overlaps with the side of the heat exchanger, increasing the contact area between the two and improving the stability of the fixation. At the same time, the fixing plate 11 covers the copper tube 34 on the side of the heat exchanger, ensuring that the copper tube 34 can be protected even if the heat exchanger shifts position. The fixing plate 11 and the heat exchanger are fixed together in the panel by the connecting plate 21. Even if the panel deforms and collapses, the fixing plate 11 and the connecting plate 21 can still support the panel and prevent the panel from directly contacting the heat exchanger, thus avoiding damage to the fins and copper tube 34 in the heat exchanger.

[0050] Example 2

[0051] like Figures 1-5 As shown, this application provides a fixing device for a heat exchanger, used to fix the side and panel of the heat exchanger. The side of the heat exchanger is provided with fins and copper tubes 34; it includes a fixing plate 11 and a connecting plate 21 that are fixed to each other.

[0052] The fixing plate 11 is fixedly connected to the side of the heat exchanger; the fixing plate 11 is provided with a covering through hole 113, which is used to cover the copper tube 34 in the side of the heat exchanger;

[0053] The connecting plate 21 is provided with a connecting through hole 213, and the connecting plate 21 and the panel are fixed by the cooperation of fasteners with the connecting through hole 213.

[0054] Furthermore, the covering through hole 113 is a through hole with a flange structure, and the flange height of the covering through hole 113 is 1.0-2.0mm.

[0055] The flange in the covering through hole 113 refers to the structure that flanges from the center of the covering through hole 113 to the outside, i.e. towards the outside of the covering through hole 113, so that a smooth surface is formed at the inner diameter of the covering through hole 113. This prevents the copper tube 34 from being scratched by the edge of the covering through hole 113 when it passes through the covering through hole 113. Once the surface of the copper tube 34 is damaged, it will crack and leak due to the stress of the system during the long-term operation of the heat exchanger.

[0056] The flange in the through hole 113 of this application can be located on the side of the fixing plate 11 that abuts against the heat exchanger, or it can be located on the side of the fixing plate 11 that is away from the heat exchanger. Regardless of which side the flange structure is located on, the flange structure with a certain height can provide a certain degree of protection for the root of the copper tube 34. Even if the panel collapses or deforms, the flange structure can still protect the root of the copper tube 34 from damage. Preferably, in order to ensure the fit between the fixing plate 11 and the side of the heat exchanger, the flange structure can be located on the side of the fixing plate 11 that does not need to abut against the side of the heat exchanger, ensuring that the fixing plate 11 and the side of the heat exchanger abut flat.

[0057] Furthermore, the fixing plate 11 has M first fastening areas 111 on its side away from the connecting plate 21. The M first fastening areas 111 are distributed at intervals in the fixing plate 11, and the first fastening areas 111 and the fixing plate 11 are located in the same plane; M is an integer greater than 0.

[0058] In this embodiment, the size of the fixing plate 11 is smaller than the size of the heat exchanger side. Specifically, in the height direction, the fixing plate 11 and the heat exchanger side are at the same height. In the horizontal plane perpendicular to the height direction, i.e., in the width direction, the size of the fixing plate 11 is smaller than the size of the heat exchanger side, only overlapping the edge of the heat exchanger side and covering the outermost row of copper tubes 34 on the heat exchanger side. In the side of the heat exchanger, the size in the height direction is much larger than the size in the width direction.

[0059] To achieve the fixation of the fixing plate 11 and the side of the heat exchanger, simply using the snap-fit ​​of the through hole 113 and the copper pipe 34 is insufficient. This application also provides a first fastening area 111 on the side of the fixing plate 11 away from the connecting plate 21. Specifically, the first fastening area 111 can be a protruding structure relative to the fixing plate 11, and the first fastening area 111 and the fixing plate 11 are located in the same plane, both of which can fit and abut against the side of the heat exchanger. The first fastening area 111 is used to achieve the fixation with the side of the heat exchanger. Specifically, the first fastening area 111 and the side of the heat exchanger can be fixed by fasteners, thereby achieving a stable connection between the fixing plate 11 and the side of the heat exchanger.

[0060] Furthermore, a first fastening through hole 112 is provided at the center of the first fastening area 111, and an arc transition portion is provided at the edge of the first fastening area 111; the number of the first fastening areas 111 is three.

[0061] The first fastening through hole 112 can specifically be a screw hole, and the diameter of the first fastening through hole 112 is the same as that of the screw hole on the side of the heat exchanger. The screw passes through the first fastening through hole 112 and the screw hole on the side of the heat exchanger in sequence to achieve fastening of the fixing plate 11 and the side of the heat exchanger. In this application, the first fastening through hole 112 is specifically as follows: Figure 1 As shown, the structure is a protruding ear-like structure. The first fastening through hole 112 is located at the center of the first fastening area 111, ensuring uniform force distribution in the first fastening area 111. Simultaneously, the edges of the first fastening area 111 are provided with rounded transition portions to prevent damage to the copper tube 34 during assembly with the side of the heat exchanger. Specifically, there are three first fastening areas 111, distributed sequentially along the height of the heat exchanger, forming fastenings at the top, middle, and bottom, further ensuring a secure fixation.

[0062] Furthermore, the connecting plate 21 has N second fastening areas 212 on its side away from the fixing plate 11. The N second fastening areas 212 are distributed at intervals in the connecting plate, and the second fastening areas 212 and the connecting plate 21 are located in the same plane; N is an integer greater than 0.

[0063] The connecting plate 21 is used to fix the panel. If the width of the connecting plate 21 is too large, it will increase the weight of the fixing device and the heat exchanger. If the width of the connecting plate 21 is too small, it will result in an unstable connection with the panel. The width of the connecting plate 21 refers to the direction perpendicular to the plane of the fixing plate 11. In this application, the width of the connecting plate 21 is set in the range of 2.5-3.5mm. At the same time, a second fastening area 212 is provided on the side of the connecting plate 21 away from the fixing plate 11. The location of the second fastening area 212 is the fastening position between the connecting plate 21 and the panel. The second fastening area 212 is used to fix the connecting plate 21 and the panel, and at the same time, it can also make up for the defect of narrow fastening position caused by the narrow width of the connecting plate 21.

[0064] Furthermore, the panel includes a side panel 31 and a bottom panel 32, and the number of the second fastening areas 212 is four, of which three of the second fastening areas 212 are fixed in the side panel 31 by fasteners, and the other second fastening area 212 is fixed in the bottom panel 32 by fasteners.

[0065] When fixing the heat exchanger, the sides of the heat exchanger are typically fixed simultaneously to both the side panel 31 and the bottom panel 32. Four second fastening areas 212 are distributed sequentially along the height direction of the connecting plate 21, which is the same as the height of the heat exchanger, and the height of the connecting plate 21 is much greater than its width. The upper three second fastening areas 212 are used to fasten to the side panel 31, and these three areas are respectively distributed at the top, middle, and bottom of the side panel 31. The lowermost second fastening area 212 is used to fasten to the bottom panel 32. The connecting plate 21 enables simultaneous connection of the heat exchanger's sides to both the side panel 31 and the bottom panel 32.

[0066] Furthermore, the connecting plate 21 also includes a connecting area 211, which is located between the second fastening area 212 and the fixing plate 11; the connecting plate 21 is provided with a connecting through hole 213, which is located in both the second fastening area 212 and the connecting area 211.

[0067] The connecting area 211 in the connecting plate 21 determines the overall strength of the connecting plate 21, and the second fastening area 212 is as follows: Figure 2 The protruding ear-shaped structure shown has the connecting through hole 213 partially located within the connecting area 211 and partially located within the second fastening area 212, so that the fastener is located at the center of the connecting plate 21, ensuring that the connecting plate 21 is subjected to uniform force in the width direction.

[0068] In this application, the positions of the second fastening area 212 and the connecting through hole 213 correspond one-to-one. When setting the second fastening area 212 and the connecting through hole 213, it is necessary to take into account the distribution of copper tubes 34 on the side of the heat exchanger. It is necessary to ensure that the connecting through hole 213 is located between two copper tubes 34, and to ensure that the screw is misaligned with the copper tubes 34 after fixing, so as not to touch the copper tubes 34.

[0069] Furthermore, in the first direction, the size of the connecting area 211 is 2.5-3.5mm; the first direction refers to the direction from the second fastening area 212 to the connecting area 211 in the plane perpendicular to the fixing plate 11.

[0070] In the first direction, the dimension of the connecting area 211 is 2.5-3.5mm, that is, the width of the connecting area 211 is about 3mm, and the height of the connecting area 211 is the same as the height of the heat exchanger. This width range ensures that the connecting plate 21 has a certain strength, while also ensuring that the weight of the fixing device remains within an acceptable range.

[0071] In this application, both the connecting area 211 and the second fastening area 212 can be configured as folded edge structures. The folded edge structure can further enhance the strength of the connecting plate 21 and prevent the connecting plate 21 from bending and deforming.

[0072] Furthermore, the top and bottom of the fixing plate 11 are provided with clearance notches, and the clearance notches are provided with arc-shaped corners.

[0073] The top and bottom of the fixing plate 11 refer to the upper and lower parts in the height direction of the fixing plate 11, while the first fastening area 111 is located in the width direction of the fixing plate 11. The clearance notch can be a U-shaped clearance structure, which can make way for the copper pipes 34 at the top and bottom of the heat exchanger; at the same time, the rounded corner can prevent the edge of the fixing plate 11 from being too sharp and causing damage to the copper pipes 34 during assembly.

[0074] Example 3

[0075] like Figures 1-5 As shown, this application provides a fixing device for fixing the side of a condenser 33 to a side panel 31 and a bottom panel 32; wherein the side of the condenser 33 refers to the side of the condenser 33 in which the copper tube 34 is integrated. The side panel 31 is located above the bottom panel 32. The side of the condenser 33 in which the copper tube 34 is located has a rectangular structure. The larger side of the rectangular structure is defined as the height direction of the condenser 33, and the smaller side of the rectangular structure is defined as the width direction of the condenser 33. In this application, the side panel 31 and the side of the condenser 33 are perpendicular to each other.

[0076] The fixing device includes a fixing plate 11 and a connecting plate 21 that are perpendicular to each other; wherein, the fixing plate 11 is used to fix the side of the condenser 33, and the connecting plate 21 is used to fix the fixing plate 11 and the side of the condenser 33 in the panel.

[0077] The height of the fixing plate 11 is approximately equal to the height of the condenser 33, and the width of the fixing plate 11 is less than the width of the condenser 33. The fixing plate 11 has a covering through-hole 113 for covering the copper tubes 34 on the side of the condenser 33. The covering through-hole 113 only needs to cover the outermost row of copper tubes 34 in the width direction of the condenser 33. The covering through-hole 113 is a through-hole with a flanged structure, and the flange height of the covering through-hole 113 is 1.5mm. The flange refers to the structure that flanges from the center of the covering through-hole 113 to the outside, i.e., towards the outside of the covering through-hole 113, so that a smooth surface is formed at the inner diameter of the covering through-hole 113, preventing the edge of the covering through-hole 113 from scratching the surface of the copper tubes 34 when they pass through the covering through-hole 113. At the same time, the flanged structure is located on the side of the fixing plate 11 that does not need to abut against the side of the condenser 33, ensuring that the fixing plate 11 and the side of the condenser 33 are in flat contact.

[0078] The fixing plate 11 has three first fastening areas 111 on its side away from the connecting plate 21. These three first fastening areas 111 are spaced apart within the fixing plate 11, and are located in the same plane as the fixing plate 11. A first fastening through hole 112 is provided at the center of each first fastening area 111. The diameter of the first fastening through hole 112 is the same as that of the screw hole on the side of the condenser 33. Screws pass through the first fastening through hole 112 and the screw hole on the side of the condenser 33 in sequence, thus fastening the fixing plate 11 to the side of the condenser 33. Specifically, the first fastening through hole 112 in this application is as follows: Figure 1 As shown, the structure is a protruding ear-like structure. The first fastening through hole 112 is located at the center of the first fastening area 111, ensuring uniform force distribution in the first fastening area 111. Simultaneously, the edges of the first fastening area 111 are provided with rounded transition portions to prevent damage to the copper tube 34 during assembly with the side of the condenser 33. Specifically, there are three first fastening areas 111, distributed sequentially along the height direction of the condenser 33, forming fastenings at the top, middle, and bottom positions, further ensuring the firmness of the fixation.

[0079] The top and bottom of the fixing plate 11 refer to the upper and lower parts in the height direction of the fixing plate 11, while the first fastening area 111 is located in the width direction of the fixing plate 11. The clearance notch can be a U-shaped clearance structure, which can make way for the copper tubes 34 at the top and bottom of the condenser 33; at the same time, the rounded corner can prevent the edge of the fixing plate 11 from being too sharp and causing damage to the copper tubes 34 during assembly.

[0080] The connecting plate 21 also includes a connecting region 211, which is located between the second fastening region 212 and the fixing plate 11. The connecting plate 21 has a connecting through hole 213, which is located in both the second fastening region 212 and the connecting region 211. Part of the connecting through hole 213 is located within the connecting region 211, and part is located within the second fastening region 212, ensuring that the fastener is positioned at the center of the connecting plate 21 and that the connecting plate 21 is subjected to uniform force in the width direction. Both the connecting region 211 and the second fastening region 212 can be configured as folded edges. Folded edges further enhance the strength of the connecting plate 21 and prevent bending and deformation. The width of the connecting region 211 is approximately 3 mm, and its height is the same as the height of the condenser 33. This width range ensures that the connecting plate 21 has sufficient strength while maintaining the weight of the fixing device within an acceptable range.

[0081] Four second fastening areas 212 are provided on the side of the connecting area 211 away from the fixing plate 11. These four second fastening areas 212 are spaced apart within the connecting plate, and are located in the same plane as the connecting plate 21. The four second fastening areas 212 are distributed sequentially along the height direction of the connecting plate 21, which is the same direction as the height of the condenser 33, and the height of the connecting plate 21 is much greater than its width. The upper three second fastening areas 212 are used to fasten to the side panel 31, and are respectively distributed at the top, middle, and bottom of the side panel 31. The lowermost second fastening area 212 is used to fasten to the bottom panel 32. The connecting plate 21 enables synchronous connection between the side of the hot condenser 33 and the side panel 31 and bottom panel 32.

[0082] In this application, the positions of the second fastening area 212 and the connecting through hole 213 correspond one-to-one. When setting the second fastening area 212 and the connecting through hole 213, it is necessary to take into account the distribution of copper tubes 34 on the side of the condenser 33. It is necessary to ensure that the connecting through hole 213 is located between the two copper tubes 34, and to ensure that the screw is misaligned with the copper tubes 34 after fixing, so as not to touch the copper tubes 34.

[0083] In this embodiment, the connecting plate 21 and the fixing plate 11 are made of hot-dip galvanized steel Q235A 0.75X1100XC material, which is not easy to rust when exposed to water, is corrosion resistant, and has high strength.

[0084] During the process of fixing the condenser 33 and the panel, firstly, the covering through hole 113 is passed through the copper tube 34, so that the fixing plate 11 and the side of the condenser 33 are fitted and snapped together; then, the screws are passed through the first fastening through hole 112 and the screw holes in the side of the condenser 33 to fix the fixing plate 11 and the side of the condenser 33. Finally, the connecting through hole 213 is aligned with the screw holes in the side panel 31 and the bottom panel 32, and the screws are passed through the connecting through hole 213 and the screw holes in the side panel 31 and the bottom panel 32 to fix the connecting plate 21, the side panel 31 and the bottom panel 32, thereby fixing the side of the condenser 33 in the side panel 31 and the bottom panel 32.

[0085] In this application, the sides of the fixing plate 11 and the condenser 33 overlap, increasing their contact area and improving the stability of the fixing. At the same time, the fixing plate 11 covers the copper tube 34 on the side of the condenser 33, ensuring that the copper tube 34 can be protected even if the condenser 33 is displaced. The fixing plate 11 and the condenser 33 are fixed together in the panel by the connecting plate 21. Even if the panel is deformed and collapsed, the fixing plate 11 and the connecting plate 21 can still support the panel and prevent the panel from directly contacting the condenser 33, which would cause damage to the fins and copper tube 34 in the condenser 33.

[0086] Example 4

[0087] like Figure 5 As shown, this application also provides an air conditioner, including the fixing device described in Embodiment 3 for fixing a heat exchanger as described above. The fixing device fixes the condenser 33 inside the air conditioner casing. Even if the air conditioner casing is subjected to external force during transportation or warehouse stacking, or if the air conditioner casing is deformed and collapsed, the fixing plate 11 and the connecting plate 21 can support the air conditioner casing and will not cause damage to the fins and copper tube 34 on the top of the condenser 33.
