Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to an outdoor unit of an air conditioner. Background Technology

[0002] The control box of an air conditioner contains circuit boards that control various components of the air conditioner, as well as electrical components such as reactors. These electrical components generate a lot of heat during operation. Due to the large amount of heat generated, the components may overheat and malfunction. Therefore, a heat dissipation device needs to be installed inside the control box to cool the components in a timely manner to ensure their normal operation.

[0003] Common sealed electrical control boxes are non-removable integral structures. After the refrigeration unit is fixed and welded inside the electrical control box, the refrigeration unit is then welded and fixed to the outdoor unit's refrigeration system. In this way, the electrical control box, refrigeration unit, and refrigeration system are welded together to form a fixed structure that cannot be disassembled. This makes it impossible to maintain the electrical control box and refrigeration unit independently. Furthermore, there is a phenomenon of cross-installation between the refrigeration unit and the electrical control box, which makes the installation and disassembly process complicated and cumbersome, and the workability poor. Utility Model Content

[0004] Based on this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide an outdoor unit for an air conditioner, which can be maintained separately by designing the heat dissipation module and the power supply box independently, and optimizes the assembly workability of the heat dissipation module and the power supply box.

[0005] To achieve the above objectives, this utility model provides an outdoor unit for an air conditioner, comprising:

[0006] Outdoor unit frame;

[0007] A heat dissipation mounting plate is detachably installed on the outdoor unit frame;

[0008] The cooling unit is disposed in the heat dissipation mounting plate;

[0009] The power supply box is detachably installed on the outdoor unit frame or the heat dissipation mounting plate. The power supply box is fitted to the heat dissipation mounting plate and seals the refrigeration unit inside the power supply box.

[0010] Furthermore, the outdoor unit of the air conditioner in this embodiment of the present invention also includes:

[0011] A refrigeration circuit system is installed on the outdoor unit frame and is connected to the refrigeration unit.

[0012] In one embodiment, the power supply box is detachably fitted with a power supply box cover.

[0013] In one embodiment, the outdoor unit frame is provided with a positioning support and a snap-fit ​​hole, and the heat dissipation mounting plate is provided with a positioning component and a snap-fit ​​component. The positioning component fits against the positioning support and the snap-fit ​​component is inserted into the snap-fit ​​hole.

[0014] In one embodiment, the outdoor unit frame includes two relatively parallel and spaced columns. Each of the two columns is provided with a positioning support and a snap-fit ​​hole. The two ends of the heat dissipation mounting plate are respectively provided with a positioning element and a snap-fit ​​element. The heat dissipation mounting plate is mounted between the two columns, and the positioning elements at both ends of the heat dissipation mounting plate are respectively attached to and abut against the positioning support of the two columns. The snap-fit ​​elements at both ends of the heat dissipation mounting plate are respectively inserted into the snap-fit ​​holes of the two columns.

[0015] In one embodiment, the positioning element is a positioning folded edge, and the positioning support part is a positioning support surface that is adapted to the shape of the positioning folded edge.

[0016] In one embodiment, the heat dissipation mounting plate is provided with a fixing part, and the refrigeration unit is fixedly mounted on the fixing part.

[0017] In one embodiment, the power supply housing and the heat dissipation mounting plate together form a sealed cavity structure, and the cooling unit is located in the cavity structure.

[0018] In one embodiment, the power supply box is provided with a return air duct and a supply air duct, the return air duct is connected to the supply air duct, and a guide fan is provided between the return air duct and the supply air duct, and the cooling unit is disposed in the return air duct.

[0019] As one implementation, a maintenance cover is detachably connected to the return air duct.

[0020] Therefore, according to the embodiment of this utility model, the outdoor unit of the air conditioner, consisting of a heat dissipation mounting plate and a refrigeration unit, is independent of the power supply box. This allows the heat dissipation mounting plate to be quickly and easily assembled onto the outdoor unit frame, facilitating the installation of the refrigeration unit. This achieves independence between the heat dissipation module and the power supply box, allowing for separate maintenance of both. Specifically, the heat dissipation mounting plate is assembled and fixed to the outdoor unit frame using detachable connections such as clips. The refrigeration unit is fixedly installed in the heat dissipation mounting plate, with its interface extending beyond the plate to facilitate connection and fixation between the refrigeration unit and the refrigeration circuit system. The power supply box is then detachably installed on the outdoor unit frame or the heat dissipation mounting plate, forming a sealed cavity structure with the heat dissipation module, achieving waterproof and dustproof effects without affecting the internal component layout. By setting up supply and return air ducts within the power supply box, and placing the refrigeration unit in the return air duct, the internal temperature of the power supply box can be cooled through the cooperation of the refrigeration unit and the guide fan. In other words, the power supply box of this utility model embodiment can be disassembled separately, and the refrigeration circuit system can be directly maintained after disassembly. Furthermore, the heat dissipation module, the power supply box and the outdoor unit frame are easy to assemble.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0032] In the following description, when referring to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. In the description of this application, it should be understood that the terms "first," "second," "third," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0033] In related technologies, the control box of an air conditioner houses circuit boards and electrical components such as reactors that control various parts of the air conditioner. These electrical components generate a large amount of heat during operation. Due to this high heat generation, the components may overheat and malfunction. Therefore, a heat dissipation device needs to be installed inside the control box to cool the components in a timely manner to ensure their normal operation. Common sealed control boxes are non-removable, integral structures. The refrigeration unit is welded and fixed inside the control box, and then the refrigeration unit is welded and fixed to the outdoor unit's refrigeration system. This interconnected and non-removable structure makes independent maintenance impossible, and the overlapping installation of the refrigeration unit and control box further complicates the assembly and disassembly process, resulting in poor operability.

[0034] Therefore, this utility model embodiment provides an outdoor unit for an air conditioner. The outdoor unit of the air conditioner according to this utility model embodiment, by designing the heat dissipation module and the power supply box independently, allows for separate maintenance and optimizes the assembly workability of the heat dissipation module and the power supply box.

[0035] Please see Figures 1 to 7 This utility model embodiment provides an outdoor unit for an air conditioner, comprising:

[0036] Outdoor unit frame 10;

[0037] The heat dissipation mounting plate 20 is detachably mounted on the outdoor unit frame 10;

[0038] The cooling unit 30 is disposed in the heat dissipation mounting plate 20;

[0039] The power supply box 40 is detachably installed on the outdoor unit frame 10 or the heat dissipation mounting plate 20. The power supply box 40 is fitted to the heat dissipation mounting plate 20 and the cooling unit 30 is sealed inside the power supply box 40.

[0040] Furthermore, the outdoor unit of the air conditioner in this embodiment of the present invention also includes:

[0041] A refrigeration circuit system is installed on the outdoor unit frame 10, and the refrigeration circuit system is connected to the refrigeration unit 30.

[0042] In this embodiment of the utility model, the heat dissipation mounting plate 20 is assembled on the outdoor unit frame 10 by a snap-fit ​​connection. Specifically, the outdoor unit frame 10 is provided with a positioning support part 11 and a snap-fit ​​hole 12, and the heat dissipation mounting plate 20 is provided with a positioning part 21 and a snap-fit ​​part 22. The positioning part 21 is fitted and abutted against the positioning support part 11, and the snap-fit ​​part 22 is inserted into the snap-fit ​​hole 12.

[0043] The outdoor unit frame 10 includes two relatively parallel and spaced columns. Each of the two columns is provided with a positioning support 11 and a snap-fit ​​hole 12. The two ends of the heat dissipation mounting plate 20 are respectively provided with a positioning member 21 and a snap-fit ​​member 22. The heat dissipation mounting plate 20 is mounted between the two columns, and the positioning members 21 at both ends of the heat dissipation mounting plate 20 are respectively attached to the positioning support 11 of the two columns. The snap-fit ​​members 22 at both ends of the heat dissipation mounting plate 20 are respectively inserted into the snap-fit ​​holes 12 of the two columns.

[0044] Therefore, it can be seen that the heat dissipation mounting plate 20 of this utility model embodiment is designed with a buckle 22 and a positioning member 21 at both ends. The two positioning members 21 can be quickly aligned and fixed with the positioning support parts 11 on the two columns. At the same time, the buckles 22 at both ends of the heat dissipation mounting plate 20 are inserted into the corresponding snap-fit ​​holes 12 to achieve snap-fit ​​fixation of the heat dissipation mounting plate 20, so that the heat dissipation mounting plate 20 can be quickly snap-fit ​​fixed on the outdoor unit frame 10. At the same time, the two positioning members 21 can prevent the heat dissipation mounting plate 20 from shaking and tipping over. After the heat dissipation mounting plate 20 is fixed to the outdoor unit frame 10, the refrigeration unit 30 is assembled and fixed on the heat dissipation mounting plate 20, and then the refrigeration unit 30 is connected to the refrigeration circuit system. Finally, the power box 40 is assembled on the outdoor unit frame 10 or the heat dissipation mounting plate 20. There is no cross-installation operation.

[0045] The positioning element 21 is a positioning folded edge, and the positioning support part 11 is a positioning support surface adapted to the shape of the positioning folded edge. Furthermore, the heat dissipation mounting plate 20 is provided with a fixing part, on which the refrigeration unit 30 is fixedly mounted. It is worth noting that the heat dissipation mounting plate 20 and the outdoor unit frame 10 of this utility model are not limited to the above-mentioned snap-fit ​​connection method, but can also be assembled together through other detachable connection methods such as screws and plug-ins.

[0046] In this embodiment of the invention, the power supply housing 40 and the heat dissipation mounting plate 20 together form a sealed cavity structure, and the cooling unit 30 is located within the cavity structure. Specifically, the power supply housing 40 is provided with a return air duct 42 and a supply air duct 43, the return air duct 42 and the supply air duct 43 are connected, and a guide fan is provided between the return air duct 42 and the supply air duct 43. The cooling unit 30 is disposed in the return air duct 42.

[0047] Therefore, in this embodiment of the present invention, the power supply box 40, together with the heat dissipation mounting plate 20 and the cooling unit 30, forms a sealed cavity structure, thereby achieving the effect of dust and water protection and preventing moisture and dust from affecting the internal circuit structure of the power supply box 40. Furthermore, in this embodiment of the present invention, the cooling unit 30 is arranged in the return air duct 42, and a guide fan is arranged between the return air duct 42 and the supply air duct 43. In this way, the cooling unit 30 can cool the airflow in the return air duct 42, and the guide fan can send the cold airflow from the supply air duct 43 into the interior of the power supply box 40 to cool the components. This cycle is repeated to achieve the heat dissipation and cooling effect inside the power supply box 40.

[0048] In this embodiment of the invention, the power supply box 40 is detachably equipped with a power supply box cover 41, and a maintenance cover 44 is detachably connected to the return air duct 42. This allows direct observation of the interior of the power supply box 40 by removing the power supply box cover 41, and separate maintenance of the cooling unit 30 by removing the maintenance cover 44, without needing to disassemble the entire power supply box 40. This simplifies the installation of the power supply box 40 and reduces the maintenance cost and difficulty of the cooling unit 30. It is worth noting that the power supply box 40 can be assembled onto the outdoor unit frame 10 or the heat dissipation mounting plate 20 using clips, screws, or other methods, which will not be elaborated further here.

[0049] In other words, after the heat dissipation mounting plate 20 of this utility model embodiment is installed and fixed on the outdoor unit frame 10, the refrigeration unit 30 is assembled on the fixing part of the heat dissipation mounting plate 20, and the refrigeration unit 30 is connected to the refrigeration circuit system. Finally, the power box 40 is directly placed on the heat dissipation mounting plate 20 and the refrigeration unit 30 is located in the return air duct 42 to complete the assembly and fixation. This can optimize the assembly workability of the heat dissipation module and the power box 40, and can also maintain the power box 40 or the refrigeration unit 30 separately, reducing the maintenance cost of both.

[0050] Therefore, in the outdoor unit of the air conditioner according to this embodiment of the present invention, the heat dissipation module, composed of the heat dissipation mounting plate 20 and the refrigeration unit 30, is independent of the power supply box 40. This allows the heat dissipation mounting plate 20 to be quickly and independently assembled onto the outdoor unit frame 10, and facilitates the installation of the refrigeration unit 30. This achieves independence between the heat dissipation module and the power supply box 40, allowing for separate maintenance of both. Specifically, the heat dissipation mounting plate 20 is assembled and fixed onto the outdoor unit frame 10 using detachable connection methods such as snap-fit ​​fasteners. The refrigeration unit 30 is fixedly installed in the heat dissipation mounting plate 20, and the interface of the refrigeration unit 30 extends... In addition to the heat dissipation mounting plate 20, to facilitate the connection and fixation of the cooling unit 30 and the refrigeration circuit system, the power supply box 40 is detachably installed on the outdoor unit frame 10 or the heat dissipation mounting plate 20, so that the power supply box 40 and the heat dissipation module form a sealed cavity structure, achieving the effect of waterproofing and dustproofing. This does not affect the installation layout of the components inside the power supply box 40. By setting the supply air duct 43 and the return air duct 42 inside the power supply box 40, and placing the cooling unit 30 in the return air duct 42, the internal temperature of the power supply box 40 can be cooled through the cooperation of the cooling unit 30 and the guide fan. In other words, the power supply box 40 of this utility model embodiment can be disassembled separately, and the refrigeration circuit system 13 can be directly maintained after disassembly. Moreover, the assembly of the heat dissipation module, the power supply box 40 and the outdoor unit frame 10 is easy.

[0051] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the outdoor unit of the air conditioner. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
