Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically to an outdoor unit of an air conditioner. Background Technology

[0002] In air conditioning systems, side-discharge outdoor units are typically installed on building facades or balconies where space is limited. Therefore, the thickness of the heat exchanger needs to be adjusted to accommodate different installation spaces. Furthermore, air conditioners with different power ratings require heat exchangers with different heat exchange areas to meet varying heat exchange needs.

[0003] However, when installing heat exchangers, heat exchangers of different thicknesses and sizes often require mounting plates of different specifications for matching installation. The mounting plates cannot be adjusted and can only be adapted to a single thickness. If the wrong size mounting plate is installed, it will cause the heat exchanger to loosen or deform, affecting its performance.

[0004] In existing technologies, the heat exchanger dimensions are typically matched with the mounting plate manually before installation. However, due to the large number of installation molds, manual visual inspection can lead to misinstallation and omissions, and there is a lack of effective error-proofing mechanisms. Summary of the Invention

[0005] This application provides an outdoor unit for an air conditioner, which at least solves the problem in related technologies where installation relies on manual judgment of whether the heat exchanger size matches the mounting plate. This manual inspection, due to the large number of installation molds, can lead to incorrect or missing installations, and lacks an effective error-proofing mechanism.

[0006] In a first aspect, this application provides an outdoor unit for an air conditioner, comprising:

[0007] The housing includes a housing air inlet and a housing air outlet, wherein the housing air inlet is located on the outer periphery of the housing and the housing air outlet is located on the front side of the housing.

[0008] A heat exchanger is disposed inside the casing, with the windward side of the heat exchanger facing the air inlet of the casing;

[0009] A fan bracket is provided inside the housing, and the fan bracket is located on the leeward side of the heat exchanger;

[0010] A fan is mounted on the fan support, with the air outlet side of the fan facing the air outlet of the casing;

[0011] The first fixing plate includes a snap-fit ​​part and a first connecting part, the first connecting part being fixedly installed on the fan bracket;

[0012] The second fixing plate includes an abutting part and a second connecting part. The abutting part abuts against the heat exchanger, so that the heat exchanger is located in the clamping space formed by the abutting part and the snap-fit ​​part. The second connecting part is fixedly connected to the first connecting part of the first fixing plate.

[0013] The first connecting part and the second connecting part are provided with a plurality of mating first mounting holes and second mounting holes. The position of the abutting part in the buckling part is adjusted according to the heat exchanger of different thickness specifications, so that the first mounting hole at different position is fixed to the second mounting hole, so that the buckling part and the abutting part cooperate to clamp the heat exchanger.

[0014] An adjustable clamping space is formed by the snap-fit ​​part of the first fixing plate and the abutment part of the second fixing plate. The size of the clamping space can be precisely adjusted by the adjustment hole group provided on the first and second connecting parts, so that the same fixing structure can be adapted to heat exchangers of various specifications, which significantly reduces the mold development cost and material management complexity.

[0015] In some embodiments, the latching portion includes a first cover plate, a second cover plate, and a third cover plate connected in sequence. The second cover plate is arranged parallel to the third cover plate. One end face of the second cover plate is connected to the housing, and the other end face of the second cover plate abuts against the heat exchanger. The third cover plate is connected to the first connecting portion.

[0016] By designing the snap-fit ​​part as a three-cover structure, multi-directional positioning and support of the heat exchanger are achieved. The first cover provides the connection base with the casing, the second cover directly abuts against the heat exchanger to achieve the main load-bearing, and the third cover ensures a reliable transition with the first connection part, making the stress distribution more uniform, improving the resistance to deformation, and also facilitating dimensional control during mass production.

[0017] In some embodiments, the second fixing plate further includes:

[0018] The abutting portion is arranged parallel to the second cover plate and the third cover plate, and the second connecting portion is arranged parallel to the first cover plate.

[0019] The parallel correspondence between the abutment portion of the second fixing plate and the second and third cover plates of the snap-fit ​​portion ensures that the bidirectional clamping force on the heat exchanger is completely balanced, avoiding deformation of the heat exchanger caused by stress concentration on one side. At the same time, the parallel arrangement of the second connecting portion and the first cover plate ensures the alignment accuracy of the adjustment hole, making the adjustment of the installation position of heat exchangers of different thicknesses more linear and controllable, reducing installation difficulty and error rate.

[0020] In some embodiments, the length of the abutting portion in the direction perpendicular to the end face of the second connecting portion is the same as the length of the third cover plate in the direction perpendicular to the end face of the first connecting portion.

[0021] When the lengths of the abutment portion and the third cover plate are the same in the direction perpendicular to their respective connection end faces, the clamping force borne by the heat exchanger can be evenly distributed on the two contact surfaces, avoiding the problem of local stress concentration. This provides a clear positioning reference for the installation process and improves installation efficiency.

[0022] In some embodiments, the length of the second connecting portion in the direction perpendicular to the end face of the abutting portion is less than the length of the first connecting portion in the direction perpendicular to the end face of the third cover plate.

[0023] By using the longer first connecting part as the main load-bearing component and the shorter second connecting part for adjustment and positioning, sufficient operating space is provided for the movement of the contact part, thus expanding the heat exchanger thickness adjustment range.

[0024] In some embodiments, the first connecting portion includes a first support plate and a second support plate connected in sequence. The first support plate is arranged parallel to the second connecting portion. The first support plate is connected to the fan bracket. The second support plate is arranged parallel to the abutment portion. The second support plate is connected to the housing.

[0025] The first support plate bears the main load from the fan bracket, while the second support plate disperses the reaction force of the heat exchanger, thereby improving the bending stiffness, reducing the deformation when subjected to torque, optimizing the airflow organization, reducing wind resistance loss, and improving the cleaning and maintenance efficiency of the heat exchanger.

[0026] In some embodiments, the second connecting portion is provided with a positioning identification mark associated with the position of the second mounting hole, and the arrangement of the positioning identification mark corresponds to the thickness specification of the heat exchanger;

[0027] The first connecting part is provided with a viewing window, which is located on the side close to the heat exchanger, and is used to identify the corresponding positioning identification mark through the viewing window.

[0028] The combination of positioning identification marks and viewing windows forms a reliable error-proof system, reducing the installation error rate. The placement of the positioning identification marks strictly corresponds to the heat exchanger thickness specifications, allowing for easy confirmation of the current compatibility through the viewing window, eliminating the need for additional measurements. This improves installation speed and completely avoids rework issues caused by incorrect specifications.

[0029] Secondly, this application provides an outdoor unit for an air conditioner, comprising:

[0030] The housing includes a housing air inlet and a housing air outlet, wherein the housing air inlet is located on the outer periphery of the housing and the housing air outlet is located on the front side of the housing.

[0031] A heat exchanger is disposed inside the casing, with the windward side of the heat exchanger facing the air inlet of the casing;

[0032] A fan bracket is provided inside the housing, and the fan bracket is located on the leeward side of the heat exchanger;

[0033] A fan is mounted on the fan bracket, with the fan's outlet side facing the air outlet of the casing;

[0034] The first fixed plate includes a first abutting part and a first connecting part. One end face of the first abutting part is connected to the housing, and the other end face of the first abutting part abuts against one end face of the heat exchanger. The first connecting part is fixedly installed on the fan bracket.

[0035] The second fixing plate includes a second abutting part and a second connecting part. The second abutting part abuts against the other end face of the heat exchanger, so that the heat exchanger is located between the first abutting part and the second abutting part. The second connecting part is fixedly connected to the first connecting part of the first fixing plate.

[0036] The first connecting part and the second connecting part are provided with a plurality of mating first mounting holes and second mounting holes. The position of the second abutting part on the first connecting part is adjusted according to the heat exchanger of different thickness specifications, so that the second mounting hole at different positions is fixed to the first mounting hole, so that the first abutting part and the second abutting part cooperate to clamp and fix the heat exchanger.

[0037] The symmetrical clamping structure formed by the first and second abutment parts effectively avoids the uneven force distribution problem that may occur with traditional unilateral fixing. Adjustment holes on the first and second connecting parts allow for precise adaptation to the heat exchanger thickness. During adjustment, the second abutment part can move smoothly along the first connecting part, enabling the clamping space to be flexibly adjusted according to the actual thickness of the heat exchanger to accommodate heat exchangers of different thicknesses.

[0038] In some embodiments, the first abutting portion and the second abutting portion are arranged in parallel, and the first connecting portion and the second connecting portion are arranged in parallel.

[0039] The parallel arrangement of the abutment and connection parts forms a stable parallelogram mechanism, which keeps the direction of force constant during adjustment, ensuring that the heat exchanger is always subjected to positive pressure on the vertical surface. This avoids positional deviation during installation, reduces the amplitude of the heat exchanger under full-speed fan operation, and extends the service life of the heat exchanger.

[0040] In some embodiments, the corresponding second mounting hole is selected according to the thickness of the heat exchanger, and the first mounting hole and the second mounting hole are fixed by fasteners, so that the second abutment portion can be moved relative to the first connecting portion to adjust the distance between the second abutment portion and the first abutment portion.

[0041] The second abutment part can move along a linear guide rail by cooperating with the first mounting hole, the second mounting hole and the fastener, to adapt to heat exchangers of different thicknesses.

[0042] Compared to related technologies, the outdoor unit of an air conditioner provided by this invention adds a second fixing plate, which is fixed by the second mounting hole of the second fixing plate cooperating with the first mounting hole of the first fixing plate. The position of the abutment part of the second fixing plate can be adjusted, so that the same fixing structure can be adapted to heat exchangers of various specifications, reducing mold development costs and material management complexity.

[0066] In existing air conditioning systems, the fan in the side-discharge outdoor unit exhausts the heat-exchanged air from the side of the unit. Ambient air is drawn in through the air inlets around the casing, flows through the heat exchanger fins for heat exchange, and the fan rotates the heat-exchanged air axially, discharging it horizontally from the front air outlet.

[0067] Since the lateral airflow force generated by the side-discharge fan will exacerbate the shaking of the heat exchanger, it is necessary to fix the heat exchanger with a fixing plate.

[0068] The mounting plate is usually designed so that both ends are connected to the casing, and a snap-fit ​​part is provided on one side for snapping the heat exchanger in place.

[0069] However, heat exchangers often come in various thicknesses, which necessitates the design of dedicated mounting plates for securing them. Installing the wrong mounting plate can cause the heat exchanger to loosen or deform, affecting its performance.

[0070] In existing technologies, the thickness specifications of the heat exchanger are usually judged manually to ensure they match the mounting plate before installation. However, due to the large number of mounting molds, manual visual inspection can lead to misinstallation, omissions, and low installation efficiency.

[0071] Furthermore, the lack of a visual display of heat exchanger specifications after installation can easily lead to errors during subsequent maintenance and disassembly.

[0072] To address the aforementioned issues, this application proposes an outdoor unit for an air conditioner. An adjustable clamping space is formed by the snap-fit ​​portion of the first fixing plate and the abutment portion of the second fixing plate, allowing the same fixing structure to accommodate heat exchangers of various specifications, significantly reducing mold development costs and material management complexity.

[0073] Figure 1 This is a partial structural diagram of the interior of the casing 100 in one embodiment of the outdoor unit of the air conditioner in this application. For example... Figure 1 As shown, the outdoor unit of the air conditioner includes a casing 100.

[0074] The housing 100 is used to form the overall appearance of the outdoor unit of the air conditioner; the top and bottom of the housing 100 are opposite ends, and the height direction of the housing 100 is from the top to the bottom; the left and right sides of the housing 100 are opposite sides, and the length direction of the housing 100 is from the left to the right; the front and rear sides of the housing 100 are opposite sides, and the thickness direction of the housing 100 is from the front to the rear.

[0075] The housing 100 includes a top plate located at the top of the housing 100 and forming the top surface of the housing 100.

[0076] The housing 100 includes a base plate 102, which is located at the bottom of the housing 100 and forms the bottom surface of the housing 100; the base plate 102 and the top plate are arranged opposite to each other along the height direction of the housing 100.

[0077] The housing 100 includes a front panel located on the front side of the housing 100 and forming the front side surface of the housing 100.

[0078] The housing 100 includes a rear side panel located at the rear of the housing 100, which forms the rear side surface of the housing 100. It should be noted that in some embodiments, the housing 100 may not include a rear side panel to increase the air intake volume of the outdoor unit of the air conditioner.

[0079] like Figure 1 and Figure 2 As shown, the housing 100 includes a first side plate 101, which is located on the left or right side of the housing 100 and is used to form the left or right side of the housing 100.

[0080] The housing 100 includes a second side plate, which is disposed opposite to the first side plate 101 along the length of the housing 100; the second side plate is located on the left or right side of the housing 100 and is used to form the left or right side of the housing 100.

[0081] It should be noted that the first side plate 101 and the second side plate are respectively located on different sides of the casing 100 in the length direction. In this embodiment, the first side plate 101 is located on the left side of the casing 100, the second side plate is located on the right side of the casing 100, and part of the air outlet of the casing 100 is located on the second side plate.

[0082] The housing 100 includes an air inlet, through which air from outside the housing 100 enters the interior of the housing 100.

[0083] There are multiple ways to position the air inlet of the housing 100, one of which is to position it on the rear side of the housing 100.

[0084] The housing 100 includes a housing 100 air outlet, which is located on the front side of the housing 100. The air inside the housing 100 is output to the outside through the housing 100 air outlet.

[0085] The outdoor unit of the air conditioner includes a fan bracket 200, which is located inside the housing 100 and is situated on the leeward side of the heat exchanger 300.

[0086] The outdoor unit of the air conditioner includes a fan, with the fan's outlet side facing the air outlet of the casing 100. Through the operation of the fan, external air is introduced into the casing 100 through the air inlet and / or internal air is discharged to the outside of the casing 100 through the air outlet.

[0087] The outdoor unit of the air conditioner includes a fan cover, which is located at the air outlet of the casing 100 and is installed on the front panel. The fan cover serves two purposes: firstly, it protects the fan from debris entering the casing 100 through the air outlet and contacting the fan, thus affecting its normal operation; secondly, it concentrates the air drawn in by the fan, thereby increasing the air speed and pressure, and ultimately increasing the fan's output airflow. In other words, the fan cover can focus the airflow out, improving heat dissipation and resulting in better cooling and heating performance.

[0088] The outdoor unit of the air conditioner includes a compressor connected to the base plate 102, and the compressor is used to drive the flow of refrigerant.

[0089] like Figure 1 and Figure 2 As shown, the outdoor unit of the air conditioner includes a heat exchanger 300, which is located inside the casing 100. The heat exchanger 300 is used to exchange heat with the air passing through it. The heat exchanger 300 is placed on the base plate 102, with the windward side of the heat exchanger 300 facing the air inlet of the casing 100, and at least part of the leeward side of the heat exchanger 300 facing the air inlet side of the fan. The operation of the fan accelerates the heat exchange between the air and the heat exchanger 300, thereby increasing the heat exchange effect of the heat exchanger 300.

[0090] The heat exchanger 300 extends from the left side of the casing 100, past the rear side, to a position near the right side of the casing 100. This increases the heat exchange area of ​​the heat exchanger 300 without changing the internal space of the casing 100, thereby increasing its heat exchange efficiency. It should be noted that the extension direction of the heat exchanger 300 is its length direction, and the direction perpendicular to its length direction is its width direction.

[0091] It should be noted that the 300mm thickness specification for heat exchangers can include narrow-fin 2-row heat exchangers, narrow-fin 3-row heat exchangers, wide-fin 2-row heat exchangers, and wide-fin 3-row heat exchangers.

[0092] like Figure 3 As shown, the outdoor unit of the air conditioner includes a first fixing plate 400. The first fixing plate 400 includes a snap-fit ​​part 410 and a first connecting part 420. The snap-fit ​​part 410 is connected to the rear side plate of the housing 100, and the first connecting part 420 is fixedly installed on the fan bracket 200.

[0093] It should be noted that the first fixing plate 400 can fix a heat exchanger 300 of a single specification through the snap-fit ​​part 410.

[0094] like Figure 4 and Figure 6 As shown, the outdoor unit of the air conditioner also includes a second fixing plate 500. The second fixing plate 500 includes an abutting portion 510 and a second connecting portion 520. The abutting portion 510 abuts against the heat exchanger 300, so that the heat exchanger 300 is located in the clamping space formed by the abutting portion 510 and the snap-fit ​​portion 410. The second connecting portion 520 is fixedly connected to the first connecting portion 420 of the first fixing plate 400.

[0095] like Figure 4 and Figure 7 As shown, the first connecting part 420 and the second connecting part 520 are provided with a plurality of mating first mounting holes 423 and second mounting holes 521.

[0096] like Figure 8 As shown, the position of the abutment part 510 within the snap-fit ​​part 410 is adjusted according to the heat exchanger 300 of different thickness specifications, so that the first mounting hole at different positions is fixed to the second mounting hole, so that the snap-fit ​​part 410 and the abutment part 510 cooperate to clamp the heat exchanger 300.

[0097] An adjustable clamping space is formed by the snap-fit ​​portion 410 of the first fixing plate 400 and the abutment portion 510 of the second fixing plate 500, allowing for adjustment of the clamping space size. The first and second mounting holes enable the same fixing structure to accommodate various specifications of heat exchangers 300, reducing mold development costs and material management complexity.

[0098] like Figure 3 As shown, the snap-fit ​​portion 410 of the first fixing plate 400 includes a first cover plate 411, a second cover plate 412, and a third cover plate 413 connected in sequence. The first cover plate 411 is perpendicular to the second cover plate 412 and the third cover plate 413. The second cover plate 412 is parallel to the third cover plate 413. One end face of the second cover plate 412 is connected to the rear side plate of the housing 100, and the other end face of the second cover plate 412 abuts against the heat exchanger 300. The third cover plate 413 is connected to the first connecting portion 420.

[0099] The first cover plate 411 provides a connection base to the housing 100, the second cover plate 412 abuts against the heat exchanger 300 to achieve the main load-bearing function, and the third cover plate 413 ensures a reliable transition with the first connection part 420.

[0100] like Figure 3As shown, the first connecting portion 420 of the first fixing plate 400 includes a first support plate 421 and a second support plate 422 connected in sequence. The first support plate 421 is arranged parallel to the second connecting portion 520 and is connected to the fan bracket 200. The second support plate is arranged parallel to the abutment portion 510 and is connected to the front side plate of the housing 100.

[0101] The first support plate 421 bears the main load from the fan bracket 200, while the second support plate 422 disperses the reaction force of the heat exchanger 300, improves the bending stiffness, and reduces the amount of deformation when subjected to torque.

[0102] In some embodiments, such as Figure 3 As shown, the first support plate 421 has multiple fixing holes 424 on both sides along the vertical direction of the second support plate 422. The fixing holes 424 are used to fix the first support plate 421 to the fan bracket 200.

[0103] In some embodiments, such as Figure 3 As shown, the first mounting holes 423 provided on the first connecting portion 420 are located on both sides of the first support plate 421 along the vertical direction of the second support plate 422, and are located on the side of the fixing hole 424 on the first support plate 421 near the heat exchanger 300. The first mounting holes 423 include a first set of first mounting holes 423 and a second set of first mounting holes 423.

[0104] It should be noted that the first mounting hole 423 may include two sets of first mounting holes 423, or one set of first mounting holes 423 or three or more sets of first mounting holes 423.

[0105] In some embodiments, the first set of first mounting holes 423 provided on the first connection portion 420 are located on the side of the second set of mounting holes close to the heat exchanger 300 along the width direction of the heat exchanger 300, and the first set of first mounting holes 423 are located inside the second set of first mounting holes 423.

[0106] like Figure 4 As shown, the abutting portion 510 of the second fixing plate 500 is arranged parallel to the second cover plate 412 and the third cover plate 413, and the second connecting portion 520 is arranged parallel to the first cover plate 411.

[0107] It should be noted that the length of the abutting part 510 is the same as the length of the second cover plate 412, so that the second connecting part 520 is parallel to and attached to the first cover plate 411.

[0108] The parallel correspondence between the abutment portion 510 of the second fixing plate 500 and the second cover plate 412 and third cover plate 413 of the snap-fit ​​portion 410 ensures that the bidirectional clamping force on the heat exchanger 300 is completely balanced. The parallel arrangement of the second connecting portion 520 and the first cover plate 411 ensures the alignment accuracy of the adjustment hole, making the adjustment of the installation position of heat exchangers 300 of different thicknesses more linear and controllable.

[0109] In some embodiments, the length of the abutment portion 510 in the direction perpendicular to the end face of the second connecting portion 520 is the same as the length of the third cover plate 413 in the direction perpendicular to the end face of the first connecting portion 420.

[0110] When the lengths of the abutment portion 510 and the third cover plate 413 are the same in the direction perpendicular to their respective connection end faces, the clamping force borne by the heat exchanger 300 can be evenly distributed on the two contact surfaces, avoiding the problem of local stress concentration. This provides a clear positioning reference for the installation process and improves installation efficiency.

[0111] In some embodiments, the length of the second connecting portion 520 in the direction perpendicular to the end face of the abutting portion 510 is less than the length of the first connecting portion 420 in the direction perpendicular to the end face of the third cover plate 413.

[0112] The longer first connecting part 420 serves as the main load-bearing component, while the shorter second connecting part 520 plays an adjustment and positioning role, providing ample operating space for the movement of the abutment part 510 and expanding the thickness adjustment range of the heat exchanger 300.

[0113] In some embodiments, such as Figure 6 and Figure 7 As shown, the second mounting holes 521 provided on the second connecting portion 520 are located on both sides of the second connecting portion 520 along the vertical direction of the abutment portion 510. The second mounting holes 521 include a first group of second mounting holes, a second group of second mounting holes, and a third group of second mounting holes.

[0114] It should be noted that the second mounting hole 521 may include three sets of second mounting holes, or it may include one set of second mounting holes, two sets of second mounting holes, or more than three sets of second mounting holes.

[0115] In some embodiments, the second set of second mounting holes and the third set of second mounting holes provided on the second connection portion 520 are arranged in the same row along the width direction of the heat exchanger 300. The second set of second mounting holes is located on the side of the third set of second mounting holes closer to the heat exchanger 300.

[0116] The first group of second mounting holes is located along the width direction of the heat exchanger 300 on the side of the third group of second mounting holes that is close to the heat exchanger 300, and the first group of second mounting holes is located inside the second group of second mounting holes and the third group of second mounting holes.

[0117] In some embodiments, a corresponding second mounting hole is selected according to the thickness of the heat exchanger 300, and the first mounting hole and the second mounting hole are fixed by fasteners, so that the abutment part 510 can move within the latching part 410 to adjust the clamping space between the abutment part 510 and the latching part 410.

[0118] By selecting the corresponding adjustment hole group for fixing, the abutment part 510 can be intuitively adjusted to the target position without the need for measuring tools during the adjustment process.

[0119] In some embodiments, the first set of first mounting holes provided on the first connecting part 420 and the first set of second mounting holes provided on the second connecting part 520 are fixed by fasteners, so that the abutment part 510 cooperates with the snap-fit ​​part 410 to snap-fit ​​and fix the heat exchanger 300 of the first thickness specification.

[0120] The second set of first mounting holes provided on the first connecting part 420 and the second set of second mounting holes provided on the second connecting part 520 are fixed by fasteners, so that the abutment part 510 cooperates with the snap-fit ​​part 410 to snap-fit ​​and fix the heat exchanger 300 of the second thickness specification.

[0121] The second set of first mounting holes provided on the first connecting part 420 and the third set of second mounting holes provided on the second connecting part 520 are fixed by fasteners, so that the abutting part 510 cooperates with the snap-fit ​​part 410 to snap-fit ​​and fix the heat exchanger 300 of the third thickness specification.

[0122] It should be noted that the first thickness specification of heat exchanger 300 can be a narrow-finned 2-row heat exchanger. The second thickness specification of heat exchanger 300 can be a narrow-finned 3-row heat exchanger. The first thickness specification of heat exchanger 300 can be a wide-finned 2-row heat exchanger.

[0123] In some embodiments, when the installed heat exchanger 300 has a thickness specification of 3 rows of wide fins, it is not necessary to install the second fixing plate 500; the heat exchanger 300 can be fixed by the snap-fit ​​portion 410 of the first fixing plate 400.

[0124] To facilitate the actual differentiation between fixed and error-proof measures on the production line, such as Figures 4 to 7 As shown, the second connecting part 520 is provided with a positioning identification mark associated with the position of the second mounting hole, and the arrangement of the positioning identification mark corresponds to the thickness specification of the heat exchanger 300.

[0125] like Figure 3 , Figure 9 and Figure 10 As shown, the first connecting part 420 is provided with a viewing window 425, which is located on the side near the heat exchanger 300 and is used to display the installation specifications of the heat exchanger 300 in conjunction with the positioning identification mark.

[0126] The combination of positioning identification marks and viewing window 425 forms a foolproof system, reducing the installation error rate. The arrangement of the positioning identification marks strictly corresponds to the 300mm thickness specification of the heat exchanger, and the current compatibility specification can be confirmed by observation through the viewing window 425, thus improving installation speed.

[0127] In some embodiments, such as Figure 4 and Figure 5 As shown, a first positioning identification mark 522 is provided on the end face of the second connecting part 520 near the first connecting part 420. For example... Figure 6 and Figure 7 As shown, a second positioning identification mark 523 is provided on the end face of the second connecting part 520 away from the first connecting part 420.

[0128] It should be noted that the second positioning identification mark 523 is located next to each group of second mounting holes 521. When installing the heat exchanger 300, the second mounting hole 521 at the corresponding second positioning identification mark 523 is selected according to the thickness specification of the heat exchanger 300.

[0129] When the snap-fit ​​portion 410 of the first fixing plate 400 clamps and fixes a heat exchanger 300 of a certain thickness through the abutment portion 510 of the second fixing plate 500, the first positioning identification mark 522 can be displayed through the viewing window 425.

[0130] This application also provides an outdoor unit for an air conditioner. The outdoor unit includes a casing. The casing includes an air inlet and an air outlet, with the air inlet located on the outer periphery of the casing and the air outlet located on the front side of the casing.

[0131] In some embodiments, the outdoor unit of the air conditioner also includes a heat exchanger. The heat exchanger is located inside the casing, with its windward side facing the air inlet of the casing.

[0132] In some embodiments, the outdoor unit of the air conditioner also includes a fan bracket. The fan bracket is located inside the casing and on the leeward side of the heat exchanger.

[0133] In some embodiments, the outdoor unit of the air conditioner also includes a fan. The fan is mounted on a fan bracket, with the fan's outlet side facing the air outlet of the unit casing.

[0134] In some embodiments, the outdoor unit of the air conditioner further includes a first fixing plate. The first fixing plate includes a first abutting portion and a first connecting portion. One end face of the first abutting portion is connected to the casing, and the other end face of the first abutting portion abuts against one end face of the heat exchanger. The first connecting portion is fixedly mounted on a fan bracket;

[0135] In some embodiments, the outdoor unit of the air conditioner further includes a second fixing plate. The second fixing plate includes a second abutting portion and a second connecting portion. The second abutting portion abuts against the other end face of the heat exchanger, so that the heat exchanger is located between the first abutting portion and the second abutting portion, and the second connecting portion is fixedly connected to the first connecting portion of the first fixing plate.

[0136] In some embodiments, the first connecting part and the second connecting part are provided with a plurality of mating first mounting holes and second mounting holes. The position of the second abutting part on the first connecting part is adjusted according to the heat exchanger of different thickness specifications, so that the second mounting hole at different positions is selected to fix it to the first mounting hole, so that the first abutting part and the second abutting part cooperate to clamp and fix the heat exchanger.

[0137] The adjustment holes on the first and second connecting parts allow for precise adaptation of the heat exchanger thickness. During adjustment, the second abutment part can move smoothly along the first connecting part, allowing the clamping space to be flexibly adjusted according to the actual thickness of the heat exchanger to accommodate heat exchangers of different thicknesses.

[0138] In some embodiments, the first abutting portion and the second abutting portion are arranged in parallel, and the first connecting portion and the second connecting portion are arranged in parallel.

[0139] The parallel abutment and connection parts maintain a constant force direction during adjustment, ensuring the heat exchanger is always subjected to positive pressure from the vertical surface. This prevents positional misalignment during installation, reduces heat exchanger vibration, and extends its service life.

[0140] In some embodiments, a corresponding second mounting hole is selected according to the thickness of the heat exchanger, and the first mounting hole and the second mounting hole are fixed by fasteners, so that the second abutment portion can move relative to the first connecting portion to adjust the distance between the second abutment portion and the first abutment portion.

[0141] The second abutment part can move along a linear guide rail by cooperating with the first mounting hole, the second mounting hole and the fastener, to adapt to heat exchangers of different thicknesses.

[0142] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0143] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
