Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to an outdoor unit for an air conditioner. Background Technology

[0002] Currently, an air conditioner outdoor unit generally includes a casing, a fan, a compressor, and a heat exchanger. The casing is formed by a left side panel, a right side panel, a front side panel, a rear side panel, a top panel, and a bottom panel, constituting the overall appearance of the outdoor unit. During the assembly of the outdoor unit, the left side panel and the left end panel of the heat exchanger are usually installed and fixed together to facilitate the subsequent assembly of the main body.

[0003] In the prior art, the structure used to install and fix the left side plate and the left end plate of the heat exchanger is usually a hook structure, or the left side plate and the left end plate of the heat exchanger are connected by fasteners such as bolts and screws to achieve the installation and fixation of the left side plate and the left end plate of the heat exchanger.

[0004] To reduce overall weight, the thickness of sheet metal such as the left side panel is reduced, resulting in a weaker hook design with lower strength. When screws are driven in, the hook cannot withstand the vertical force of the screws, making it easy for the hook structure to come loose, resulting in poor connection reliability and reduced production efficiency. Utility Model Content

[0005] This utility model solves, to at least a certain extent, one of the technical problems in the related art.

[0006] Therefore, this application aims to provide an outdoor air conditioning unit that, by setting a fixing device at the end of the mounting plate and the heat exchanger, can pre-fix the relative positions of the mounting plate and the end of the heat exchanger when the operator connects and fixes the mounting plate and the heat exchanger. Furthermore, since the overall structure of the fixing device can withstand the vertical impact force during installation, it avoids the separation of the mounting plate and the end of the heat exchanger during the fixing operation, thereby improving production and assembly efficiency.

[0007] To achieve the above objectives, this utility model provides an outdoor unit for an air conditioner, comprising:

[0008] The housing has a side plate on one side in the thickness direction as a mounting plate.

[0009] A fan, which is located inside the casing;

[0010] A compressor, which is located inside the housing;

[0011] A heat exchanger is disposed inside the housing, with one side of the heat exchanger close to the mounting plate;

[0012] A first positioning part is disposed on the mounting plate;

[0013] A fixing device, wherein the fixing device is disposed at the end of the heat exchanger and the mounting plate, comprises:

[0014] A first connecting plate is used to connect to the end of the heat exchanger;

[0015] An insertion part is provided on the side of the first connecting plate near the mounting plate. The insertion part is arranged along the height direction of the housing and has a mounting cavity for inserting the mounting plate.

[0016] A second positioning part is provided at the insertion part;

[0017] A fastener that connects the first positioning part and the corresponding second positioning part;

[0018] When the mounting plate is inserted into the mounting cavity and the corresponding sidewall abuts against the sidewall of the mounting cavity, the first positioning part and the corresponding second positioning part correspond to each other or are spaced apart along the height direction.

[0019] In the technical solution, by setting fixing devices at the ends of the mounting plate and the heat exchanger, when workers need to assemble the mounting plate and the heat exchanger, the workers move the mounting plate until its end is located in the mounting cavity. At this time, the corresponding side wall of the mounting plate abuts against the side wall of the mounting cavity, thereby enhancing the stability of the connection between the mounting plate and the heat exchanger ends and preventing the mounting plate and the heat exchanger from separating when subjected to vertical impact force. The first positioning part and the corresponding second positioning part correspond to each other or are spaced apart along the height direction. At this time, the relative position of the mounting plate and the heat exchanger in the horizontal direction is fixed. Workers can adjust the position of the mounting plate in the vertical direction according to the position of the first positioning part and its corresponding second positioning part, thereby improving the production assembly efficiency.

[0020] In some embodiments of this application, a positioning plate is provided at one end of the mounting plate facing the mounting cavity, and the mounting cavity has a pre-positioning port for the positioning plate to be inserted. When the end of the mounting plate is embedded in the mounting cavity, the positioning plate passes through the positioning port to the outside of the mounting cavity.

[0021] When the side wall of the mounting plate abuts against the side wall of the mounting cavity, and the positioning plate is inserted into the prepositioning port, the first positioning part and the corresponding second positioning part correspond to each other.

[0022] In the technical solution, the positioning plate and the pre-positioning port are connected and interlocked, so that when the end of the mounting plate is embedded in the mounting cavity, the positioning plate passes through the pre-positioning port, thereby determining the position of the mounting plate and the end of the heat exchanger in the height direction of the casing, and further improving the production and assembly efficiency.

[0023] In some embodiments of this application, the positioning plate has a chamfer on the side facing the pre-positioning port.

[0024] In the technical solution, by setting a chamfer, the length of the side wall of the positioning plate near the prepositioning port in the height direction of the housing is less than the length of the prepositioning port in the height direction of the housing, thereby reducing the accuracy requirements when the positioning plate is inserted into the prepositioning port and further improving the production and assembly efficiency.

[0025] In some embodiments of this application, the insertion portion includes:

[0026] An abutment plate is located on the side of the first connecting plate near the mounting plate, the abutment plate is connected to the first connecting plate, and the abutment plate abuts against the mounting plate;

[0027] A bent plate is located on the side of the abutment plate facing the mounting plate. The bent plate is connected to the abutment plate on the side away from the first connecting plate, and the mounting cavity is formed between the bent plate and the abutment plate.

[0028] In the technical solution, the horizontal position of the mounting plate and the heat exchanger is determined by moving the mounting plate so that its sidewall facing the mounting cavity abuts against the sidewall of the mounting cavity facing the mounting plate.

[0029] In some embodiments of this application, the first connecting plate, the abutting plate, and the bending plate are formed by bending the same plate.

[0030] In the technical solution, by setting the first connecting plate, the abutment plate and the bending plate on the same plate, the production cost of the fixing device is reduced, while the installation and replacement of the fixing device is more operable, thus saving design costs.

[0031] In some embodiments of this application, the bending plate includes:

[0032] A first contact plate is connected to the abutment plate, and the plane of the first contact plate forms an angle with the plane of the abutment plate, wherein the angle is an acute angle.

[0033] The second contact plate is connected to the side of the first contact plate away from the abutment plate, and the plane of the second contact plate is parallel to the plane of the abutment plate.

[0034] The mounting plate has a protrusion on the side away from the heat exchanger. When the end of the mounting plate is inserted into the mounting cavity, the protrusion near the second contact plate abuts against the second contact plate.

[0035] In the technical solution, by limiting the positional relationship between the first contact plate, the second contact plate, and the abutment plate, the position of the two side walls that are close to each other in the mounting cavity is limited. This makes the position of the end of the mounting plate in the mounting cavity more stable when it moves into the mounting cavity. At the same time, the cooperation between the protrusion and the second contact plate enables the end of the mounting plate to be quickly positioned in the mounting cavity, thereby improving the production and assembly efficiency.

[0036] In some embodiments of this application,

[0037] The first positioning part is the first positioning hole;

[0038] The second positioning part is the second positioning hole;

[0039] The fastener is used to pass through both the first positioning hole and the second positioning hole simultaneously to connect the mounting plate and the insertion part.

[0040] In the technical solution, when the worker moves the end of the mounting plate into the mounting cavity, the first positioning hole and its corresponding second positioning hole coincide. The worker then connects the mounting plate and the insertion part by inserting fasteners through the first positioning hole and the corresponding second positioning hole. Since the insertion part is connected to the first connecting plate and the first connecting plate is fixed to the heat exchanger end wall, the mounting plate is connected to the heat exchanger end.

[0041] In some embodiments of this application, the first connecting plate is provided with a connecting hole, which is used to form a plug-in fit with the heat exchange tube at the end of the heat exchanger. Multiple connecting holes are provided at intervals along the height direction of the casing, and the positions of the connecting holes correspond one-to-one with the multiple bent portions of the heat exchange tubes of the heat exchanger.

[0042] In the technical solution, by setting multiple connecting holes, when the first connecting plate abuts against the end wall of the heat exchanger, the bent part of the heat exchange tube of the heat exchanger passes through the connecting holes, so as to fix the relative position of the first connecting plate and the heat exchanger in the height direction of the casing, thereby improving the stability of the connection between the first connecting plate and the end of the heat exchanger.

[0043] In some embodiments of this application, a reinforcing strip is provided on the side of the first connecting plate away from the heat exchanger, and the reinforcing strip is arranged around the edge of the connecting hole.

[0044] In the technical solution, by setting up a reinforcing strip, when the bent part of the heat exchanger tube passes through the connecting hole, the reinforcing strip protects the connection between the bent part of the heat exchanger tube and the end of the heat exchanger, thereby reducing the possibility of damage to the connection between the bent part of the heat exchanger tube and the heat exchanger.

[0045] In addition, this application also provides an outdoor unit for an air conditioner, which includes:

[0046] The housing has a side plate on one side in the thickness direction as a mounting plate.

[0047] A fan, which is located inside the casing;

[0048] A compressor, which is located inside the housing;

[0049] A heat exchanger is disposed inside the housing, with one side of the heat exchanger close to the mounting plate;

[0050] A first positioning part is disposed on the mounting plate;

[0051] A positioning plate is disposed on the side of the mounting plate facing the heat exchanger;

[0052] A fixing device, wherein the fixing device is disposed at the end of the heat exchanger and the mounting plate, comprises:

[0053] A first connecting plate has a through hole for inserting with the heat exchange tube at the end of the heat exchanger.

[0054] A baffle is provided on the side of the first connecting plate near the mounting plate. The baffle is arranged along the height direction of the housing and has a pre-positioning port for the positioning plate to be inserted.

[0055] A second positioning part is provided at the insertion part;

[0056] A fastener that connects the first positioning part and the corresponding second positioning part;

[0057] When the positioning plate is inserted into the pre-positioning port and the corresponding side wall of the mounting plate abuts against the positioning plate, the first positioning part and the corresponding second positioning part correspond to each other.

[0058] In the technical solution, by setting a fixing device on the mounting plate and the end of the heat exchanger, when the operator needs to perform a screw-driving operation to connect the mounting plate and the end of the heat exchanger together, the operator moves the mounting plate so that the positioning plate extends through the pre-positioning port and moves until the end wall of the mounting plate facing the baffle abuts against the baffle, thereby fixing the relative position of the mounting plate and the end of the heat exchanger, so that the operator can subsequently use fasteners to connect and fix the mounting plate and the end of the heat exchanger.

[0076] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0077] In this application, the outdoor unit of the air conditioner includes a casing, and a side plate on one side of the casing in the thickness direction is set as a mounting plate. Inside the casing, there is a heat exchanger, a fan, a compressor, and a fixing device. The fixing device fixes the relative position of the mounting plate and the end of the heat exchanger, so that when the heat exchanger and the mounting plate are fixed with screws, the mounting plate and the end of the heat exchanger will not separate due to vertical force, thereby improving production efficiency and the reliability of screw fixing.

[0078] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0079] In one illustrative embodiment of the outdoor unit of the air conditioner of this utility model, the outdoor unit includes a housing, which forms the overall appearance of the outdoor unit; the top and bottom of the housing are opposite ends of the housing.

[0080] In some embodiments, the housing includes a top plate located at the top of the housing for forming the top surface of the housing.

[0081] In some embodiments, refer to Figure 1 and Figure 2 The housing includes a base plate 100, which is located at the bottom of the housing and forms the bottom surface of the housing. The base plate 100 and the top plate are arranged opposite each other along the height direction of the housing.

[0082] In some embodiments, the housing includes a side plate for connecting the top plate and the bottom plate 100. The side plate, the top plate, and the bottom plate 100 together enclose the overall appearance of the housing. The side plate on one side of the housing thickness direction is a mounting plate 200.

[0083] In some embodiments, refer to Figure 1 and Figure 3 The mounting plate 200 is provided with a first positioning part 300.

[0084] In some embodiments, the outdoor unit of the air conditioner includes a compressor located inside the casing, which is used to drive the flow of refrigerant.

[0085] In some embodiments, the outdoor unit of the air conditioner includes a fan located inside the casing. By operating the fan, air from outside the casing is introduced into the casing through the air inlet, and air from inside the casing is transported to the outside through the air outlet, thereby achieving air circulation.

[0086] In some embodiments, the outdoor unit of the air conditioner includes a heat exchanger 400 located inside the casing, which is used to exchange heat with the air passing through it.

[0087] In some embodiments, the heat exchanger 400 is placed on the base plate 100.

[0088] In existing technology, a fixing device 500 is typically provided between the end wall of the heat exchanger 400 and the mounting plate 200 to fix the relative position of the mounting plate 200 and the heat exchanger 400 before screwing, thereby reducing the probability of separation between the mounting plate 200 and the heat exchanger 400 due to vertical force on their side walls during screwing. However, in actual operation, the fixing device 500 is usually set as a hook structure. Due to the lightweight sheet metal, the hook structure has poor strength and cannot withstand the vertical force generated when the screw is driven in, which easily causes disengagement, resulting in separation between the mounting plate 200 and the heat exchanger 400, leading to poor reliability.

[0089] Based on this, this application provides a fixing device 500 that can connect the end wall of the heat exchanger 400 and the mounting plate 200 together, thereby meeting the actual assembly needs of the outdoor unit of the air conditioner.

[0090] In some embodiments, refer to Figures 1-6 The outdoor unit of the air conditioner includes a fixing device 500, which is located at the ends of the heat exchanger 400 and the mounting plate 200. The fixing device 500 is used to fix the ends of the heat exchanger 400 and the mounting plate 200 so that the mounting plate 200 and the heat exchanger 400 can be stably attached together when the operator is performing screw-driving operations, thus avoiding separation.

[0091] In some embodiments, refer to Figure 1 and Figure 2 The fixing device 500 includes a first connecting plate 510, which is used to connect to the end of the heat exchanger 400.

[0092] In some embodiments, refer to Figures 1-4 The fixing device 500 includes an insertion part 520, which is disposed on the side of the first connecting plate 510 near the mounting plate 200. The insertion part 520 is arranged along the height direction of the housing and has a mounting cavity 600 for the mounting plate 200 to be inserted.

[0093] In some embodiments, the fixing device 500 includes a second positioning part 700, which is disposed on the insertion part 520. The second positioning part 700 is used to cooperate with the first positioning part 300. Since the insertion part 520 is connected to the first connecting plate 510, the first connecting plate 510 and the mounting plate 200 are connected, thereby connecting and fixing the mounting plate 200 and the end of the heat exchanger 400.

[0094] In some embodiments, the fixing device 500 includes a fastener for connecting the first positioning part 300 and the corresponding second positioning part 700 to connect the insertion part 520 and the mounting plate 200. Since the end of the heat exchanger 400 is connected to the first connecting plate 510, the connection and fixing of the mounting plate 200 and the end of the heat exchanger 400 are realized.

[0095] Through the above technical solution, by setting fixing devices 500 at the ends of the mounting plate 200 and the heat exchanger 400, when workers need to perform screw-driving operations to connect the ends of the mounting plate 200 and the heat exchanger 400 together, the fixing devices 500 are first fixed to the heat exchanger 400 using wire ties. Then, the heat exchanger 400 with the fixing devices 500 installed is placed on the base plate 100. Finally, the mounting plate 200 is inserted into the mounting cavity 600, completing the relative fixation of the mounting plate 200 and the heat exchanger 400. When the mounting plate 200 is inserted into the mounting cavity 600, and the corresponding side wall of the mounting plate 200 abuts against the side wall of the mounting cavity 600, the first positioning part 300 and the corresponding second positioning part 700 correspond to each other or are spaced apart along the height direction. At this time, the mounting plate 200 and the heat exchanger 400 are fixed in relative position in the horizontal direction. The operator adjusts the position of the mounting plate 200 in the height direction of the casing according to the position of the first positioning part 300 and its corresponding second positioning part 700, so that the first positioning part 300 and its corresponding second positioning part 700 are aligned, so that the operator can operate the fasteners to fix the mounting plate 200 and the heat exchanger 400.

[0096] In some embodiments, refer to Figures 3-6 The insertion part 520 includes an abutment plate 521, which is located on the side of the first connecting plate 510 near the mounting plate 200. The abutment plate 521 is connected to the first connecting plate 510 and abuts against the mounting plate 200. The abutment plate 521 is used to support the mounting plate 200. When the operator vertically drives the fastener into the first positioning part 300 and the second positioning part 700, the mounting plate 200 is subjected to a vertical impact force in the direction of the abutment plate 521. At this time, the mounting plate 200 is pressed against the abutment plate 521. The abutment plate 521 applies a reaction force to the mounting plate 200 so that the mounting plate 200 will not tilt in the thickness direction of the heat exchanger 400 when subjected to vertical force, making the position of the mounting plate 200 more stable.

[0097] In some embodiments, refer to Figures 3-6 The insertion part 520 includes a bent plate 522, which is located on the side of the abutment plate 521 facing the mounting plate 200. The bent plate 522 is connected to the side of the abutment plate 521 away from the first connecting plate 510, and a mounting cavity 600 is formed between the bent plate 522 and the abutment plate 521. When the operator inserts the mounting plate 200 into the mounting cavity 600, the end wall of the mounting plate 200 abuts against the side wall of the mounting cavity 600 facing the mounting plate 200, thereby determining the horizontal position of the mounting plate 200 and the heat exchanger 400.

[0098] In some embodiments, refer to Figures 7-11 The first connecting plate 510, the abutment plate 521, and the bending plate 522 are formed by bending the same plate, thereby reducing the production cost of the fixing device 500 and making the fixing device 500 more operable for installation and replacement, so as to realize the generalized design of the main structure of the fixing device 500 and save the overall cost.

[0099] In some embodiments, refer to Figure 3 and Figure 8 A positioning plate 800 is provided at one end of the mounting plate 200 facing the mounting cavity 600. The mounting cavity 600 has a pre-positioning port 900 for the positioning plate 800 to be inserted. When the end of the mounting plate 200 is embedded in the mounting cavity 600, the positioning plate 800 passes through the pre-positioning port 900 to the outside of the mounting cavity 600. That is, when the end wall of the mounting plate 200 facing the mounting cavity 600 abuts against the side wall of the mounting cavity 600 facing the mounting plate 200, and the positioning plate 800 is inserted into the pre-positioning port 900, the first positioning part 300 and the corresponding second positioning part 700 correspond to each other to achieve a relatively fixed position between the mounting plate 200 and the fixing device 500 in the height direction of the housing. Thus, when the positioning plate 800 is inserted into the pre-positioning port 900, the position of the mounting plate 200 relative to the fixing device 500 in both the horizontal direction and the height direction of the housing is limited, and the relative position between the mounting plate 200 and the heat exchanger 400 is fixed.

[0100] In some embodiments, refer to Figure 8 The positioning plate 800 has a chamfer 801 on the side facing the prepositioning port 900. When the mounting plate 200 moves into the mounting cavity 600, the positioning plate 800 moves accordingly towards the prepositioning port 900. Since the end of the positioning plate 800 has a chamfer 801, the length of the end wall of the positioning plate 800 away from the mounting plate 200 in the height direction of the housing is less than the length of the prepositioning port 900 in the height direction of the housing. This reduces the accuracy required when the positioning plate 800 is inserted into the prepositioning port 900, thereby enabling quick insertion of the positioning plate 800 and the prepositioning port 900 and improving the assembly efficiency of the mounting plate 200 and the fixing device 500.

[0101] In some embodiments, refer to Figure 3 and Figure 11 The bending plate 522 includes a first contact plate 523, which is connected to the abutment plate 521. The plane of the first contact plate 523 and the plane of the abutment plate 521 form an angle, and the angle is acute. When the end wall of the mounting plate 200 abuts against the side wall of the mounting cavity 600, since the angle between the first contact plate 523 and the abutment plate 521 is acute, the prism on the side of the end wall of the mounting plate 200 away from the abutment plate 521 abuts against the side wall of the first contact plate 523 near the abutment plate 521. This makes it less likely that the mounting plate 200 will be displaced in the mounting cavity 600 when subjected to a vertical impact force, thereby increasing the stability of the end wall of the mounting plate 200 in the mounting cavity 600.

[0102] In some embodiments, refer to Figure 7 and Figure 8 The bending plate 522 includes a second contact plate 524, which is connected to the side of the first contact plate 523 away from the abutment plate 521. The plane of the second contact plate 524 is parallel to the plane of the abutment plate 521. The mounting plate 200 is provided with a protrusion 201 on the side away from the heat exchanger 400. When one side of the end wall of the mounting plate 200 abuts against the first contact plate 523, the side of the protrusion 201 close to the second contact plate 524 abuts against the second contact plate 524, so as to limit the position of the end wall of the mounting plate 200 in the mounting cavity 600 during the process of the mounting plate 200 being inserted into the mounting cavity 600.

[0103] In some embodiments, refer to Figure 9 and Figure 10 The first positioning part 300 is a first positioning hole, which is located on the mounting plate 200. Multiple first positioning holes are provided so that the mounting plate 200 can be connected to the fixing device 500 at different positions, making the connection between the mounting plate 200 and the fixing device 500 more secure.

[0104] In some embodiments, the second positioning part 700 is a second positioning hole, which is located on the abutment plate 521. Multiple second positioning holes are provided, and the positions of the second positioning holes correspond one-to-one with the first positioning holes, so as to increase the connection points between the mounting plate 200 and the abutment plate 521, thereby improving the reliability of the connection between the mounting plate 200 and the first connecting plate 510.

[0105] With the above technical solution, when the end wall of the mounting plate 200 is inserted into the mounting cavity 600, the relative position of the mounting plate 200 and the first connecting plate 510 is initially fixed. At this time, the positions of the first positioning hole and the corresponding second positioning hole are in one-to-one correspondence. The operator passes the fastener through the first positioning hole and the corresponding second connecting hole 582 at the same time to realize the connection and fixation of the mounting plate 200 and the first connecting plate 510.

[0106] In some embodiments, fasteners may be bolts, screws, nuts, etc.

[0107] In some embodiments, refer to Figures 3-6 To further enhance the connection stability between the mounting plate 200 and the fixing device 500, the fixing device 500 includes a second connecting plate 530. The second connecting plate 530 is connected to the side of the first connecting plate 510 near the mounting plate 200. The second connecting plate 530 is arranged parallel to the abutment plate 521, and the second connecting plate 530 is located on the side of the abutment plate 521 away from the base plate 100. The second connecting plate 530 is provided with a second positioning hole, and the mounting plate 200 is provided with a first positioning hole at a corresponding position. When the end wall of the mounting plate 200 is inserted into the mounting cavity 600, the second connecting plate 530 abuts against the mounting plate 200, and the first positioning hole aligns with the second positioning hole, so as to facilitate the installation of fasteners by the operator, thereby realizing the connection between the mounting plate 200 and the second connecting plate 530 and enhancing the reliability of the connection between the mounting plate 200 and the fixing device 500.

[0108] In some embodiments, the second connecting plate 530 and the abutment plate 521 are not on the same plane. The second connecting plate 530 fits the mounting plate 200 and the corresponding plate position to enhance the flexibility of the position of the second connecting plate 530, thereby increasing the applicability of the fixing device 500, so that the staff can set the second connecting plate 530 according to the design requirements of the mounting plate 200.

[0109] In some embodiments, the first connecting plate 510, the second connecting plate 530, the abutment plate 521, and the bending plate 522 are formed by bending the same plate to reduce the production cost of the fixing device 500.

[0110] In some embodiments, refer to Figure 3 and Figure 5 The second connecting plate 530 is provided with a first reinforcing plate 540 on the side away from the abutment plate 521. The first reinforcing plate 540 extends toward the thickness direction of the heat exchanger 400. The first reinforcing plate 540 is used to enhance the structural strength of the second connecting plate 530, so that when the operator inserts the fastener into the first positioning hole and the second positioning hole, the relative position of the second connecting plate 530 and the first connecting plate 510 does not change, thereby improving the connection stability between the second connecting plate 530 and the mounting plate 200.

[0111] In some embodiments, to further increase the overall structural stability of the fixing device 500, a second reinforcing plate 550 is provided on the side of the first connecting plate 510 away from the mounting plate 200. The second reinforcing plate 550 is provided along the height direction of the housing, and the angle between the plane of the second reinforcing plate 550 and the plane of the first connecting plate 510 is a right angle, so as to increase the overall structural strength of the first connecting plate 510 and further reduce the probability of deformation of the first connecting plate 510 when the abutment plate 521 is subjected to a vertical impact force.

[0112] In some embodiments, refer to Figure 9 and Figure 10 The first connecting plate 510 has a connecting hole 560, which is used to form a plug-in fit with the heat exchange tube at the end of the heat exchanger 400. When the end wall of the mounting plate 200 is inserted into the mounting cavity 600, the bent part of the heat exchange tube protrudes from the connecting hole 560. At this time, the first connecting plate 510 abuts against the side of the heat exchanger 400 facing the first connecting plate 510, thereby protecting the end wall of the heat exchanger 400 with the first connecting plate 510. At the same time, it makes the relative position of the first connecting plate 510 and the heat exchanger 400 more stable, so that the relative position of the mounting plate 200 inserted into the mounting cavity 600 and the heat exchanger 400 is more stable, which makes it easier for workers to install fasteners into the first positioning hole and the second positioning hole, thereby improving production efficiency.

[0113] In some embodiments, multiple connecting holes 560 are provided along the height direction of the housing, and the positions of the connecting holes 560 correspond one-to-one with the curved portions of the heat exchange tubes, making the relative positions of the first connecting plate 510 and the end of the heat exchanger 400 more stable, thereby improving the stability of the connection between the mounting plate 200 and the end of the heat exchanger 400.

[0114] In some embodiments, a reinforcing strip 570 is provided on the side of the first connecting plate 510 away from the heat exchanger 400. The reinforcing strip 570 is arranged around the edge of the connecting hole 560. The reinforcing strip 570 is used to protect the connection between the bent portion of the heat exchange tube and the heat exchanger 400, thereby reducing the possibility that the bent portion of the heat exchange tube may be damaged during the installation process between the first connecting plate 510 and the end of the heat exchanger 400.

[0115] In some embodiments, refer to Figure 4 and Figure 6Since a flange 101 is usually provided on the base plate 100, in order to further improve the applicability of the fixing device 500, the fixing device 500 can connect and fix the positions of the mounting plate 200, the base plate 100 and the heat exchanger 400 while connecting the mounting plate 200 to the end of the heat exchanger 400, so that the heat exchanger 400 after the fixing device 500 is installed can be placed on the base plate 100. The fixing device 500 includes a third connecting plate 580, which is connected to the abutment plate 521. The third connecting plate 580 is located on the side of the abutment plate 521 close to the base plate 100, and the third connecting plate 580 and the abutment plate 521 are integrally formed.

[0116] In some embodiments, the third connecting plate 580 is provided with a first connecting hole 581, and the flange 101 is provided with a second connecting hole 582. The first connecting hole 581 and the second connecting hole 582 are correspondingly arranged. When the worker places the assembled mounting plate 200 and heat exchanger 400 on the base plate 100, the position of the first connecting hole 581 corresponds to the position of the second connecting hole 582. The worker inserts fasteners into the first connecting hole 581 and the second connecting hole 582 at the same time to realize the connection between the flange 101 and the fixing device 500, thereby fixing the position of the mounting plate 200 and the heat exchanger 400 on the base plate 100.

[0117] In some embodiments, the third connecting plate 580 and the abutment plate 521 are not located on the same plane. The position of the third connecting plate 580 can be adjusted according to the position of the flange 101 to increase the applicability of the fixing device 500.

[0118] In addition, this application also provides an outdoor air conditioner unit, which includes a housing for forming the overall appearance of the outdoor air conditioner unit; the top and bottom of the housing are opposite ends of the housing.

[0119] In some embodiments, the housing includes a top plate located at the top of the housing for forming the top surface of the housing.

[0120] In some embodiments, the housing includes a base plate 100, which is located at the bottom of the housing and forms the bottom surface of the housing. The base plate 100 and the top plate are disposed opposite each other along the height direction of the housing.

[0121] In some embodiments, the housing includes a side plate for connecting the top plate and the bottom plate 100. The side plate, the top plate, and the bottom plate 100 together enclose the overall appearance of the housing. The side plate on one side of the housing thickness direction is a mounting plate 200.

[0122] In some embodiments, the mounting plate 200 is provided with a first positioning part 300.

[0123] In some embodiments, a positioning plate 800 is provided on the side of the mounting plate 200 facing the heat exchanger 400.

[0124] In some embodiments, the outdoor unit of the air conditioner includes a compressor located inside the casing, which is used to drive the flow of refrigerant.

[0125] In some embodiments, the outdoor unit of the air conditioner includes a fan located inside the casing. By operating the fan, air from outside the casing is introduced into the casing through the air inlet, and air from inside the casing is transported to the outside through the air outlet, thereby achieving air circulation.

[0126] In some embodiments, the outdoor unit of the air conditioner includes a heat exchanger 400 located inside the casing, which is used to exchange heat with the air passing through it.

[0127] In some embodiments, the heat exchanger 400 is placed on the base plate 100.

[0128] The outdoor unit of the air conditioner includes a fixing device 500, which is located at the ends of the heat exchanger 400 and the mounting plate 200. The fixing device 500 is used to fix the ends of the heat exchanger 400 and the mounting plate 200 so that the mounting plate 200 and the heat exchanger 400 can be stably attached together when the operator is performing screw-driving operations, thus avoiding separation.

[0129] In some embodiments, refer to Figure 1 and Figure 2 The fixing device 500 includes a first connecting plate 510, which is used to connect to the end of the heat exchanger 400.

[0130] In some embodiments, the fixing device 500 includes a baffle plate disposed on the side of the first connecting plate 510 near the mounting plate 200. The baffle plate is disposed along the height direction of the housing and has a pre-positioning port 900 for the positioning plate 800 to be inserted.

[0131] In some embodiments, the fixing device 500 includes a second positioning part 700, which is disposed on the insertion part 520. The second positioning part 700 is used to cooperate with the first positioning part 300 to facilitate the connection between the insertion part 520 and the mounting plate 200. Since the insertion part 520 is connected to the first connecting plate 510, the mounting plate 200 and the end of the heat exchanger 400 are connected and fixed.

[0132] In some embodiments, the fixing device 500 includes a fastener for connecting the first positioning part 300 and the corresponding second positioning part 700 to connect the insertion part 520 and the mounting plate 200. Since the end of the heat exchanger 400 is connected to the first connecting plate 510, the connection and fixing of the mounting plate 200 and the end of the heat exchanger 400 are realized.

[0133] Through the above technical solution, by setting the fixing device 500 at the ends of the mounting plate 200 and the heat exchanger 400, when the operator needs to perform screw-driving operation to connect the ends of the mounting plate 200 and the heat exchanger 400 together, the operator moves the mounting plate 200 so that the positioning plate 800 extends through the pre-positioning port 900 and moves to the end wall of the mounting plate 200 facing the baffle and abuts against the baffle, so as to fix the relative position of the mounting plate 200 and the end of the heat exchanger 400, so that the operator can use fasteners to connect and fix the mounting plate 200 and the end of the heat exchanger 400.

[0134] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
