Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to an air conditioner outdoor unit. BACKGROUND

[0002] The heat exchanger is one of the key components of the air conditioner outdoor unit, mainly responsible for heat transfer and exchange. The heat exchanger in the air conditioner outdoor unit cooperates with the heat exchanger in the air conditioner indoor unit, through the circulation of refrigerant, to realize heat transfer, and together complete the refrigeration or heating cycle of the air conditioner, to ensure efficient and stable operation of the air conditioning system.

[0003] In some air conditioner outdoor units, especially in air conditioners with a large number of units, the heat exchanger of the air conditioner outdoor unit is usually of a multi-row structure. In the prior art, the end of the heat exchanger extending towards the compressor is usually connected to the casing by fasteners such as bolts, while the constraint between the end of the heat exchanger away from the compressor and the casing is less, so that gaps of different distances are generated between each row of heat exchangers. When the wind passes through the heat exchanger at a high speed, the wind will flow out from the gaps, resulting in low working efficiency of the heat exchanger of the air conditioner outdoor unit. At the same time, when the gaps between different rows of heat exchangers are large, a whistle-like tone will be produced, which is a high-frequency abnormal sound and is likely to cause user complaints.

[0004] Therefore, in the prior art, the installation method of the heat exchanger cannot well meet the requirements of the air conditioner outdoor unit. CONTENT OF THE UTILITY MODEL

[0005] In view of the deficiencies in the related art, the present application provides an air conditioner outdoor unit, which sets a clamping member on the top of the heat exchanger, and clamps multiple heat exchange plates by the clamping member, to avoid the adverse effects caused by the large gaps between the heat exchange plates.

[0006] The present application provides an air conditioner outdoor unit, comprising:

[0007] A casing, comprising a casing air inlet and a casing air outlet, the casing air inlet is arranged on the outer periphery of the casing, and the casing air outlet is arranged on the front side of the casing;

[0011] The heat exchanger further comprises:

[0012] The heat exchange plates are configured in multiple ways, and the multiple heat exchange plates are arranged from the windward side to the leeward side of the heat exchanger; the heat exchange plates are arranged along the height direction of the heat exchanger;

[0013] A clamping element is located at the top of the heat exchanger; the clamping element includes:

[0014] Two clamping plates are provided, one of which contacts the windward side of the heat exchanger, and the other of which contacts the leeward side of the heat exchanger, so that the clamping member can simultaneously clamp multiple heat exchange plates; the clamping plate located on the leeward side of the heat exchanger is rotatably connected to the connecting plate.

[0015] A connecting piece is provided at the top of the heat exchanger and is used to connect the two clamping pieces.

[0016] This technical solution uses a clamping element at the top of the heat exchanger to simultaneously clamp multiple heat exchange plates, preventing excessive gaps between them and thus reducing air leakage and improving heat exchange efficiency. It also prevents heat exchange plates from shifting or loosening, ensuring the stability of the heat exchanger structure and improving the reliability and lifespan of the outdoor air conditioning unit. By configuring the clamping element with two clamping plates, which contact the windward and leeward sides of the heat exchanger respectively, the clamping element can apply clamping force evenly to the multiple heat exchange plates from both sides, avoiding uneven force on one side and ensuring a tight arrangement of the heat exchange plates. To prevent excessive gaps between heat exchange plates, the clamping plates on the leeward side of the heat exchanger are connected to the connecting plates via a rotating connection, increasing the degree of freedom of the clamping plates. During the assembly of the clamping components and the heat exchanger, the angle between the clamping plates and the connecting plates can be flexibly adjusted, ensuring a precise fit between the clamping plates and the leeward side of the heat exchanger, thus improving the convenience and adaptability of the clamping component installation process. A connecting plate is also provided to connect the two clamping plates, allowing them to work together as a whole, increasing the structural stability of the clamping component and ensuring uniform clamping force applied to the windward and leeward sides of the heat exchanger.

[0018] This technical solution provides a protrusion on the clamping plate and an insertion part on the heat exchanger. The protrusion is inserted into the insertion part, and the cooperation between the protrusion and the insertion part prevents the clamping plate from detaching from the heat exchanger, thereby increasing the clamping effect of the clamping parts on the heat exchanger.

[0019] In some embodiments, the connecting piece is provided with a connecting portion, which is located on the side of the connecting piece facing the heat exchanger; the top of the heat exchanger is provided with a passing portion for inserting the connecting portion.

[0030] A clamping piece, which is arranged on the top of the heat exchanger; the clamping piece comprises:

[0031] Two clamping pieces, one of which is in contact with the windward side of the heat exchanger, and the other of which is in contact with the leeward side of the heat exchanger, so that the clamping piece clamps the plurality of heat exchange plates at the same time;

[0032] A connecting piece, located at the top of the heat exchanger, is used to connect the two clamping pieces;

[0033] A limiting piece is connected to the connecting piece, and the limiting piece and two clamping pieces are arranged along the outer edge of the connecting piece; the limiting piece is in contact with the end face of the heat exchanger.

[0034] This technical solution uses a clamping component at the top of the heat exchanger to simultaneously clamp multiple heat exchange plates, preventing excessive gaps between them and thus reducing air leakage and improving heat exchange efficiency. It also prevents heat exchange plates from shifting or loosening, ensuring structural stability and enhancing the reliability and lifespan of the outdoor air conditioning unit. The clamping component comprises two clamping plates, each contacting the windward and leeward sides of the heat exchanger respectively. This ensures even clamping force from both sides, preventing uneven force distribution and ensuring a tight arrangement of the plates, preventing excessive gaps. A connecting plate connects the two clamping plates, allowing them to work together as a whole, increasing structural stability and ensuring uniform clamping force on both sides. Finally, a limiting plate is included in the clamping component, contacting the end face of the heat exchanger to position the clamping component within the heat exchanger.

[0035] In some embodiments, a clearance portion is provided at the connection between the clamping plate and the connecting plate, the clearance portion being disposed toward the heat exchanger and used to accommodate the edge or corner of the heat exchanger.

[0036] This technical solution provides a clearance portion at the connection between the clamping plate and the connecting plate to prevent interference between the clamping plate or connecting plate and the edge or corner of the heat exchanger; the clearance portion can also accommodate the edge or corner of the heat exchanger, so that the clamping part fits more tightly with the windward or leeward side of the heat exchanger, thereby enhancing the clamping effect of the clamping part on the heat exchange plate.

[0037] In some embodiments, the clamping plate located on the leeward side of the heat exchanger is rotatably connected to the connecting plate.

[0038] This technical solution increases the degree of freedom of the clamping plate by using a rotating connection between the clamping plate located on the leeward side of the heat exchanger and the connecting plate. During the assembly process of the clamping component and the heat exchanger, the angle between the clamping plate and the connecting plate can be flexibly adjusted, so that the clamping plate and the leeward side of the heat exchanger can be accurately fitted, improving the convenience and adaptability of the clamping component installation process.

[0039] In some embodiments, the clamping piece is provided with a protruding portion, which protrudes from one side of the clamping piece towards the heat exchanger; the heat exchanger is provided with an insertion portion, which is recessed from the windward side and / or the leeward side of the heat exchanger, and is used for inserting the protruding portion.

[0070] In order to make the purpose and the embodiments of the present application more clear, the following will combine the drawings in the exemplary embodiments of the present application to make a clear and complete description of the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application.

[0071] It should be noted that the brief description of the terms in the present application is only for the convenience of understanding the following described embodiments, but is not intended to limit the embodiments of the present application. Unless otherwise specified, these terms should be understood according to their ordinary and general meanings.

[0072] The terms "first", "second", and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit the specific order or sequence, unless otherwise specified. It should be understood that the terms used in this way can be interchanged under appropriate circumstances.

[0073] The terms "include" and "have" and any variations thereof are intended to cover but not exclusive inclusion, for example, a product or device including a series of components does not necessarily limit to all the components clearly listed, but can include other components not clearly listed or inherent to these products or devices.

[0074] The air conditioner outdoor unit provided by the present application can have various implementation forms. For example, Figures 1-16 One specific embodiment of the air conditioner outdoor unit of the present application.

[0075] For example, Figure 1As shown, the air conditioner outdoor unit provided in the present application comprises a casing 100, which is used to form the overall appearance of the air conditioner outdoor unit; the top of the casing 100 and the bottom of the casing 100 are opposite two ends, and the height direction of the casing 100 is from the top of the casing 100 to the bottom of the casing 100; the left side of the casing 100 and the right side of the casing 100 are opposite two sides, and the length direction of the casing 100 is from the left side of the casing 100 to the right side of the casing 100; the front side of the casing 100 and the back side of the casing 100 are opposite two sides, and the thickness direction of the casing 100 is from the front side of the casing 100 to the back side of the casing 100.

[0076] As shown in the drawings, Figure 2 The casing 100 comprises a top plate 110, which is located at the top of the casing 100 and is used to form the top surface of the casing 100.

[0077] As shown in the drawings, Figure 3 The casing 100 comprises a bottom plate 140, which is located at the bottom of the casing 100 and is used to form the bottom surface of the casing 100; the bottom plate 140 and the top plate 110 are oppositely arranged along the height direction of the casing 100.

[0078] As shown in the drawings, Figure 2 The casing 100 comprises a front panel 120, which is located at the front side of the casing 100 and is used to form the front side surface of the casing 100.

[0079] The casing 100 comprises a back side plate, which is located at the back side of the casing 100 and is used to form the back side surface of the casing 100. It should be noted that, in some embodiments, the casing 100 can also not comprise the back side plate, so as to increase the air inlet amount of the air conditioner outdoor unit.

[0080] As shown in the drawings, Figures 2-4 The casing 100 comprises a first side plate 130, which is located at the left side or the right side of the casing 100 and is used to form the left side surface or the right side surface of the casing 100.

[0081] The casing 100 comprises a second side plate, which is oppositely arranged with the first side plate 130 along the length direction of the casing 100; the second side plate is located at the left side or the right side of the casing 100 and is used to form the left side surface or the right side surface of the casing 100.

[0082] It should be noted that the first side plate 130 and the second side plate are respectively arranged at two sides different in the length direction of the casing 100; in the present embodiment, the first side plate 130 is located at the left side of the casing 100, the second side plate is located at the right side of the casing 100, and part of the casing air outlet 102 is arranged on the second side plate.

[0083] As shown in the drawings, Figure 3As shown, the housing 100 includes a partition 150, which is located inside the housing 100. The partition 150 is arranged along the height direction of the housing 100 and divides the interior of the housing 100 into a first chamber and a second chamber.

[0084] like Figure 1 As shown, the housing 100 includes a housing air inlet 101, which is connected to the first chamber. Air from outside the housing 100 enters the housing 100 through the housing air inlet 101.

[0085] There are multiple ways to position the air inlet 101 in the housing. One way is to position it on the rear side of the housing 100. Another way is to position it not only on the rear side of the housing 100, but also on the side wall of the first chamber away from the second chamber.

[0086] like Figure 2 As shown, the housing 100 includes a housing air outlet 102, which is located on the front side of the housing 100 and communicates with the first chamber. Air inside the housing 100 is output to the outside through the housing air outlet 102.

[0087] like Figures 2-3 As shown, the outdoor unit of the air conditioner includes a fan 300, which is located in the first chamber, with the air outlet side of the fan 300 facing the air outlet 102 of the casing. Through the operation of the fan 300, external air is introduced into the casing 100 through the casing air inlet 101 and / or air inside the casing 100 is discharged to the outside of the casing 100 through the casing air outlet 102.

[0088] In this embodiment, the fan 300 is an axial flow fan 300, and the rotation axis of the fan 300 is set along the thickness direction of the casing 100.

[0089] like Figure 1 As shown, the outdoor unit of the air conditioner includes a fan cover 200, which is located at the air outlet 102 of the casing and is installed on the front panel 120. The fan cover 200 can protect the fan 300 from entering the casing 100 through the air outlet 102 and contacting the fan 300, thus affecting the normal operation of the fan 300. On the other hand, it can concentrate the air drawn in by the fan 300, thereby increasing the speed and pressure of the air and ultimately increasing the air output of the fan. In other words, the fan cover 200 can focus the air out, improve the heat dissipation effect, and make the cooling and heating effects better.

[0090] like Figure 3 and Figure 4As shown, the air conditioner outdoor unit comprises a heat exchanger 400, which is arranged in the casing 100 and used for heat exchange of air passing through the heat exchanger 400; the heat exchanger 400 is placed on the bottom plate 140, the windward side of the heat exchanger 400 is arranged towards the air inlet 101 of the casing, and at least part of the leeward side of the heat exchanger 400 is arranged towards the air inlet side of the fan 300; the heat exchange between the air and the heat exchanger 400 is accelerated by the operation of the fan 300, thereby increasing the heat exchange effect of the heat exchanger 400.

[0091] In some embodiments, the windward side of the heat exchanger 400 is in contact with the side wall of the casing 100, which can support the heat exchanger 400 by the casing 100 on the one hand, and increase the space of the leeward side of the heat exchanger 400 on the other hand, thereby facilitating the arrangement of components such as the fan 300.

[0092] The heat exchanger 400 extends from the left side of the casing 100 to a position close to the right side of the casing 100 through the rear side of the casing 100, so that the heat exchanger 400 is substantially L-shaped, and the heat exchange area of the heat exchanger 400 can be increased without changing the internal space of the casing 100, thereby increasing the heat exchange efficiency of the heat exchanger 400. It should be noted that the extension direction of the heat exchanger 400 is the length direction of the heat exchanger 400.

[0093] The heat exchanger 400 comprises heat exchange plates arranged along the height direction of the heat exchanger 400; in the case of the same size of the heat exchange plates, the more the number of the heat exchange plates, the better the heat exchange effect and the higher the heat exchange efficiency of the heat exchanger 400. In an air conditioner with a large number of matches, the heat exchanger 400 usually comprises a plurality of heat exchange plates arranged from the windward side to the leeward side of the heat exchanger 400, so that the heat exchanger 400 has strong heat exchange capacity. It should be noted that the windward side to the leeward side of the heat exchanger 400 is the thickness direction of the heat exchanger 400, that is, the plurality of heat exchange plates are arranged along the thickness direction of the heat exchanger 400.

[0094] The heat exchanger 400 is connected with an end plate, which is located at one end of the heat exchanger 400 close to the partition plate 150 and extends along the height direction of the casing 100. The end plate and the partition plate 150 are connected with each other, so that the partition plate 150 fixes and constrains the heat exchanger 400, thereby increasing the firmness of the installation of the heat exchanger 400, and the heat exchanger 400 can support the partition plate 150 through the end plate, thereby increasing the firmness of the connection of the partition plate 150.

[0095] In the present embodiment, the end plate, the partition plate 150, the first side plate 130, the top plate 110, the bottom plate 140 and the front plate 120 jointly define a second chamber.

[0096] As shown in FIG. 1, the air conditioner outdoor unit comprises a casing 100, a heat exchanger 400, a fan 300, a partition plate 150, a first side plate 130, a top plate 110, a bottom plate 140 and a front plate 120. Figure 3As shown, the air conditioner outdoor unit comprises a compressor 500, the compressor 500 is arranged in the second chamber, the compressor 500 is connected to the bottom plate 140, and the compressor 500 is used to drive the refrigerant flow.

[0097] As shown, Figure 3 As shown, the air conditioner outdoor unit comprises an electric control box 600, the electric control box 600 is arranged near the top of the shell 100. The electric control box 600 is provided with an electric control board, and the electric control board is connected with the compressor 500 and the fan 300 to control the working of the compressor 500 and the fan 300.

[0098] In the prior art, the end of the heat exchanger 400 away from the compressor 500 lacks fixing constraints, which easily leads to a large gap between the heat exchange plates, and air passing through the heat exchanger 400 easily penetrates through the gap between the heat exchange plates, thereby reducing the heat exchange efficiency of the heat exchanger 400; and when the gap between the heat exchange plates is relatively large, air passing through the gap between the heat exchange plates also produces a noise similar to a whistle tone, which easily reduces the user experience.

[0099] Therefore, in the present application, the clamping piece 700 is arranged on the top of the heat exchanger 400 to clamp multiple heat exchange plates at the same time, so as to constrain and limit the thickness dimension of the heat exchanger 400, to prevent the gap between the heat exchange plates from being too large, thereby ensuring the heat exchange efficiency and effect of the heat exchanger 400.

[0100] As shown, Figure 5 , Figure 6 and Figures 8-16 As shown, the clamping piece 700 comprises two clamping pieces, one clamping piece is arranged on the windward side of the heat exchanger 400 and in contact with the windward side of the heat exchanger 400; and the other clamping piece is arranged on the leeward side of the heat exchanger 400 and in contact with the leeward side of the heat exchanger 400, so as to clamp multiple heat exchange plates at the same time.

[0101] As shown, Figures 9-16 The clamping piece 700 comprises a connecting piece 730, the connecting piece 730 is used to connect the two clamping pieces, and the clamping pieces are located on the top of the heat exchanger 400. One end of the clamping piece is connected to the connecting piece 730, and the other end of the clamping piece is arranged in a direction away from the connecting piece 730 along the height direction of the heat exchanger 400.

[0102] By deforming the clamping piece in a direction away from the other clamping piece, the distance between the two clamping pieces is increased, and multiple heat exchange plates are arranged between the two clamping pieces, so that the clamping piece 700 can clamp multiple heat exchange plates.

[0103] The clamping piece 700 is defined to form a mounting portion; the mounting portion is arranged along the length direction of the heat exchanger 400, and the mounting portion is arranged to allow multiple heat exchange plates to pass through at the same time along the length direction of the heat exchanger 400. It should be noted that the mounting portion is defined by the two clamping pieces.

[0104] In some embodiments, the mounting portion is a through slot arranged along the length direction of the heat exchanger 400, and the slot opening of the through slot is arranged downward, so that the plurality of heat exchange plates are arranged through the mounting portion, and the clamping member 700 clamps the top of the heat exchanger 400.

[0105] When the clamping member 700 and the heat exchanger 400 are in contact with each other, the clamping member 700 will shield the heat exchanger 400, which will reduce the contact area of the heat exchanger 400 with the air, thereby reducing the heat exchange effect of the heat exchanger 400.

[0106] Based on this, as shown in Figure 6 and Figure 8 , the clamping member 700 is provided with a ventilation portion 701 for air to pass through the clamping member 700, so that the air can pass through the clamping member 700 and be in contact with the heat exchanger 400, thereby reducing the shielding of the clamping member 700 to the heat exchanger 400.

[0107] The clamping sheet is provided with a ventilation portion 701, so that air passes through the clamping sheet and is in contact with the windward side or the leeward side of the heat exchanger 400, thereby reducing the blocking effect of the clamping sheet on the heat exchanger 400.

[0108] In some embodiments, the ventilation portion 701 is a long hole arranged along the height direction of the heat exchanger 400, and the ventilation portion 701 is arranged in multiple, and the plurality of ventilation portions 701 are arranged along the length direction of the heat exchanger 400.

[0109] The connecting sheet 730 is provided with a ventilation portion 701, so that air passes through the connecting sheet 730 and is in contact with the top of the heat exchanger 400, thereby reducing the blocking effect of the connecting sheet 730 on the heat exchanger 400.

[0110] In this embodiment, for the convenience of description, the clamping sheet located on the leeward side of the heat exchanger 400 is referred to as the first clamping sheet 710, and the clamping sheet located on the windward side of the heat exchanger 400 is referred to as the second clamping sheet 720.

[0111] In some embodiments, in order to ensure the clamping effect of the clamping member 700 on the heat exchanger 400, the clamping member 700 is arranged in multiple, and the plurality of clamping members 700 are arranged along the extension direction of the heat exchanger 400, so as to increase the clamping effect of the clamping member 700 on the heat exchanger 400, so that the clamping member 700 uniformly clamps the heat exchanger 400, and avoid that the gap between the heat exchange plates is too large in some places.

[0112] As shown in Figure 6 , when the clamping member 700 and the end of the heat exchanger 400 cooperate with each other, since the end of the heat exchanger 400 is provided with a bending section 401, in order to increase the cooperation effect of the clamping member 700 and the end of the heat exchanger 400, as shown in Figure 11As shown, the clamping member 700 includes a limiting piece 740, which is connected to the connecting piece 730. The limiting piece 740 is in contact with the end face of the heat exchanger 400. The limiting piece 740 is provided with a positioning part 702, and the bent section 401 passes through the positioning part 702 to position the connection position between the clamping member 700 and the end of the heat exchanger 400, and can also increase the clamping effect of the clamping member 700 on the heat exchanger 400.

[0113] In some embodiments, the positioning part 702 is a positioning hole through which the bent section 401 passes, so that the limiting piece 740 can fit more tightly with the end face of the heat exchanger 400.

[0114] like Figure 8 As shown, when two adjacent heat exchange plates have different lengths, they may form a step. This step is located on the leeward side of the heat exchanger 400. To enable the clamping member 700 to simultaneously clamp multiple heat exchange plates at the step, as shown... Figure 12 As shown, the first clamping plate 710 is configured as two parts, and the two parts are at different distances from the second clamping plate 720 along the thickness direction of the heat exchanger 400, so that the two parts respectively contact the two heat exchange plates of different lengths.

[0115] In some embodiments of this application, the clamping member 700 is made of sheet metal to give it high strength, thereby giving it a better clamping effect on the heat exchanger 400 and increasing its service life.

[0116] When the clamping part 700 is made of sheet metal, such as Figure 10 As shown, a clearance portion 703 is provided at the connection between the clamping plate and the connecting plate 730. The clearance portion 703 is positioned towards the heat exchanger 400 and is used to accommodate the edge or corner of the heat exchanger 400 to prevent the clamping plate or connecting plate 730 from contacting or interfering with the edge or corner of the heat exchanger 400, which could damage the fins 420. Furthermore, the clearance portion 703 can also accommodate the edge or corner of the heat exchanger 400, making the clamping member 700 fit more tightly with the windward or leeward side of the heat exchanger 400, thereby increasing the clamping effect of the clamping member 700 on the heat exchange plate.

[0117] In some other embodiments of this application, the clamping member 700 is made of plastic so that the clamping member 700 has a small weight and avoids the clamping member 700 from damaging the heat exchanger 400.

[0118] When the clamping part 700 is made of plastic, the clamping plate has low strength. When multiple heat exchange plates are inserted through the mounting part by deforming the clamping plate, the clamping plate is prone to breakage due to excessive deformation.

[0119] Based on this, in some embodiments, such as Figure 13As shown, the first clamping sheet 710 located at the leeward side of the heat exchanger 400 is rotationally connected to the connecting sheet 730 to increase the degree of freedom of the first clamping sheet 710, and the angle between the first clamping sheet 710 and the connecting sheet 730 can be flexibly adjusted during the assembly of the clamping piece 700 and the heat exchanger 400, so that the first clamping sheet 710 and the leeward side of the heat exchanger 400 are precisely fitted, the convenience and adaptability of the installation process of the clamping piece 700 are improved, and the assembly error is reduced.

[0120] When the clamping piece 700 clamps the heat exchanger 400, the first clamping sheet 710 is rotated to increase the angle between the first clamping sheet 710 and the connecting sheet 730, so as to increase the distance between the first clamping sheet 710 and the second clamping sheet 720, so that the heat exchanger 400 is clamped into the mounting portion, and then the first clamping sheet 710 is reversely rotated to make the first clamping sheet 710 and the leeward side of the heat exchanger 400 contact each other, and the second clamping sheet 720 and the windward side of the heat exchanger 400 contact each other, so that the clamping piece 700 clamps the heat exchanger 400.

[0121] As shown in Figure 13 , the clamping sheet is provided with a protruding portion 750, and the protruding portion 750 protrudes from the side of the clamping sheet facing the heat exchanger 400; the heat exchanger 400 is provided with an insertion portion, the insertion portion is recessed on the windward side and / or the leeward side of the heat exchanger 400, the insertion portion is correspondingly arranged with the protruding portion 750, and the insertion portion is used for inserting the protruding portion 750. Through the cooperation of the protruding portion 750 and the insertion portion, the protruding portion 750 is inserted into the insertion portion, so as to prevent the clamping sheet from being separated from the heat exchanger 400, and increase the clamping effect of the clamping piece 700 on the heat exchanger 400.

[0122] As shown in Figure 10 , the heat exchange plate includes fins 420 for contacting air; the fins 420 are arranged in multiple, and the multiple fins 420 are arranged along the extension direction of the heat exchanger 400, and have gaps between adjacent fins 420 to increase the heat exchange area of the fins 420 and air, thereby increasing the heat exchange effect of the heat exchanger 400.

[0123] As shown in Figure 10 , the heat exchange plate includes heat exchange pipes 410, and the heat exchange pipes 410 are arranged between the multiple fins 420, and the heat exchange pipes 410 flow with refrigerant, and the refrigerant flows in the heat exchange pipes 410 to exchange heat with air through the heat exchange pipes 410 and the fins 420.

[0124] As shown in Figure 14 and Figure 16As shown, the heat exchange tube 410 includes a straight section 402, which is arranged along the extension direction of the heat exchanger 400; the straight section 402 passes through the fins 420 and is located inside the heat exchanger 400; typically, multiple straight sections 402 are provided, arranged along the height direction of the heat exchanger 400. It should be noted that adjacent straight sections 402 arranged along the height direction of the heat exchanger 400 have gaps between them.

[0125] The heat exchange tube 410 includes a bent section 401, which is connected to a straight section 402 and is used to change the orientation of the heat exchange tube 410. The bent section 401 is located at the end of the heat exchange plate. One bent section 401 is connected to two adjacent straight sections 402, that is, two adjacent straight sections 402 are connected to each other through a bent section 401.

[0126] It should be noted that the specific structure of the finned heat exchanger is common knowledge in this field and will not be described in detail here.

[0127] In some embodiments, such as Figure 14 As shown, the insertion part is the gap between adjacent straight segments 402 arranged along the height direction of the heat exchanger 400. When the protrusion 750 is inserted into the gap, one straight segment 402 is located above the protrusion 750 and the other straight segment 402 is located below the protrusion 750.

[0128] like Figure 15 As shown, the connecting piece 730 is provided with a connecting portion 760, which is located on the side of the connecting piece 730 facing the heat exchanger 400; the top of the heat exchanger 400 is provided with a through portion, which is used for the insertion of the connecting portion 760, so that the connecting portion 760 is inserted into the through portion to prevent the connecting piece 730 from falling out of the heat exchanger 400, thereby increasing the clamping effect of the clamping member 700 on the heat exchanger 400.

[0129] In some embodiments, such as Figure 16 As shown, the through part is the gap between adjacent fins 420, and the connecting part 760 passes through the gap between adjacent fins 420 and connects with the heat exchange tube 410 to increase the clamping effect of the clamping member 700 on the heat exchanger 400, and also to prevent the clamping member 700 from moving along the length direction of the heat exchanger 400.

[0130] like Figure 15 As shown, the end of the connecting part 760 away from the connecting piece 730 is provided with a mating part 761. The mating part 761 is adapted to the circumferential shape of the heat exchange tube 410. At least part of the outer periphery of the heat exchange tube 410 is provided in the mating part 761 so that the connecting part 760 is connected to the heat exchange tube 410.

[0131] The air conditioner outdoor unit sets the clamping piece 700 on the top of the heat exchanger 400, so that the clamping piece 700 clamps multiple heat exchange plates at the same time, to avoid the gap between the heat exchange plates being too large, reduce air leakage, and improve heat exchange efficiency; the clamping piece 700 can also prevent the heat exchange plates from being displaced or loosened, ensure the stability of the structure of the heat exchanger 400, and further improve the reliability and service life of the air conditioner outdoor unit.
