[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] In the description of the utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] The electric control box of the air conditioner will generate a lot of heat when it is running. In order to cool down the control unit in the electric control box, a radiator is usually added to the electric control box, and part of the refrigerant pipeline is used to exchange heat with the radiator to achieve an effective heat dissipation effect. In the related art, a mounting bracket is added inside the electric control box, and the radiator is connected to the outer shell of the electric control box through the mounting bracket. However, this kind of electric control box has many accessories, and it is necessary to first assemble the mounting bracket into the outer shell, and then install the radiator, which is cumbersome to install.

[0037] To solve the above problems, an embodiment of the utility model provides an electric control box 1000, in which the outer shell 100 of the electric control box 1000 and the boss 120 of the bottom wall of the accommodating cavity 110 are an integrally formed structure, and the heat dissipation component 200 can be directly installed on the boss 120. Compared with the solution of separately setting a mounting bracket, this reduces the number of accessories and reduces the production cost; during installation, the second positioning portions 211 on both sides of the heat dissipation component 200 are aligned with the first positioning portions 130 of the boss 120, and then the second positioning portions 211 are matched with the first positioning portions 130 to position and fix the heat dissipation component 200 on the boss 120. The entire installation process is simple and convenient. The specific structure and function of the electric control box 1000 provided in the embodiment of the utility model will be further explained in conjunction with text and drawings below.

[0038] Reference Figure 1 and Figure 2 As shown, the electric control box 1000 according to the embodiment of the first aspect of the utility model includes: a shell 100 and a heat dissipation assembly 200, the shell 100 is provided with a accommodating cavity 110, the bottom wall of the accommodating cavity 110 is provided with a boss 120, the boss 120 and the shell 100 are an integrally formed structure, the top of the boss 120 is provided with a first positioning portion 130, the heat dissipation assembly 200 is provided with a mounting structure 240 adapted to the refrigerant pipeline 230, the refrigerant pipeline 230 can be installed in the mounting structure 240, and the heat dissipation assembly 200 is provided with a second positioning portion 211 on the side facing the boss 120, and the second positioning portion 211 cooperates with the first positioning portion 130 to fix the heat dissipation assembly 200.

[0039] According to the electric control box 1000 of the embodiment of the utility model, the outer shell 100 and the boss 120 on the bottom wall of the accommodating cavity 110 are integrally formed structures. Specifically, the boss 120 and the outer shell 100 can be made into one piece by injection molding, stamping molding and other processes. Compared with the solution of separately setting a mounting bracket, it is beneficial to reduce the number of accessories, reduce the assembly process, and reduce the production cost; during installation, after the second positioning portion 211 of the heat dissipation component 200 is aligned with the first positioning portion 130 of the boss 120, the second positioning portion 211 is engaged with the first positioning portion 130 to position and fix the heat dissipation component 200 on the boss 120, and the refrigerant pipeline 230 is assembled on the mounting structure 240 to fix the refrigerant pipeline 230. The whole installation process is simple and convenient, and the installation efficiency is high. The heat dissipation component 200 is used to dissipate the heat of the control unit in the electric control box 1000, thereby improving the stability of the operation of the electric control box 1000.

[0040] It should be noted that the number of the first positioning portions 130 can be one, two, or three. The number of the first positioning portions 130 is not limited herein. The number of the second positioning portions 211 is the same as the number of the first positioning portions 130, so that the first positioning portions 130 and the second positioning portions 211 correspond one-to-one to each other for positioning.

[0041] Reference Figure 1 , Figure 3 and Figure 4 As shown, it can be understood that the shell 100 has a side wall and the side wall is provided with an open opening 150 connected to the accommodating cavity 110. During the installation process, the circuit of the electric control board and the refrigerant pipeline 230 can pass through the opening 150 of the side wall of the shell 100 to enter the accommodating cavity 110; the side wall on the other side of the shell 100 is also provided with a vent 140. The vent 140 cooperates with the opening 150 of the side wall of the shell 100 to realize the convection of the gas in the accommodating cavity 110, and can make the hot air in the accommodating cavity 110 flow out more smoothly from the vent 140 or the opening 150 of the side wall of the shell 100, which is beneficial to enhance the heat dissipation effect.

[0042] It should be noted that after the shell 100 and the boss 120 are integrally formed, the connection between the shell 100 and the boss 120 is stable, and the shell 100 and the boss 120 do not need to be fixed by fixing parts (such as screws, studs, etc.), which can prevent the boss 120 from loosening or even falling off due to loosening of the fixing parts.

[0043] Reference Figure 1 and Figure 4 As shown, it can be understood that the housing 100 is a sheet metal part, and the bottom wall of the sheet metal part is stamped toward the accommodating cavity 110 to form a boss 120. The manufacturing process of the entire housing 100 is simple, the production efficiency is high, and it is conducive to reducing production costs.

[0044] It should be noted that the bottom wall of the sheet metal is stamped toward the accommodating cavity 110 to form a boss 120, and the outer wall of the boss 120 facing away from the accommodating cavity 110 is in direct contact with the air. The contact area between the entire shell 100 and the air is large, which is beneficial to improving the heat dissipation capacity of the shell 100.

[0045] Reference Figure 3 and Figure 4According to the electric control box 1000 of the first embodiment of the utility model, the first positioning portion 130 is constructed as at least one pair of positioning buckles 131 protruding from the upper end surface of the boss 120. Specifically, the lower end of the positioning buckle 131 is connected to the boss 120, and the upper end protrudes from the top surface of the boss 120. The two positioning buckles 131 are symmetrically arranged on both sides of the boss 120. The second positioning portion 211 is constructed as at least one pair of card grooves 212 formed on the surface of the heat dissipation component 200. The body is that the slot 212 is formed by the concave surface of the heat dissipation component 200 and the shape of the slot 212 matches the positioning buckle 131. The two slots 212 are symmetrically arranged on both sides of the heat dissipation component 200. During installation, the slots 212 on both sides of the heat dissipation component 200 are aligned with the positioning buckles 131 on both sides of the boss 120, and then the corresponding positioning buckles 131 are inserted into the slots 212, so that the heat dissipation component 200 is positioned and fixed on the boss 120. The entire installation process is simple and convenient.

[0046] It is understandable that the number of the positioning buckles 131 can also be two pairs, three pairs, etc., and the number of the positioning buckles 131 is not limited here, and the number of the second positioning portions 211 is the same as the first positioning portions 130. Specifically, when the number of the positioning buckles 131 is a pair, the first positioning portion 130 can be set in the middle of the boss 120, and the second positioning portion 211 is also set in the middle of the heat dissipation component 200. The first positioning portion 130 and the second positioning portion 211 at this position can cooperate to better fix the heat dissipation component 200; in addition, the first positioning portion 130 can also be constructed as a positioning column, a positioning sheet, etc., and the shape of the second positioning portion 211 is constructed to match the shape of the first positioning portion 130. For example, when the first positioning portion 130 is a positioning column, the second positioning portion 211 is a positioning hole. A plurality of positioning columns can be set on the upper end surface of the boss 120, and the plurality of positioning columns are arranged at intervals. When the positioning columns are inserted into the positioning holes, the positioning effect can also be achieved.

[0047] Reference Figure 4 and Figure 5 As shown, it can be understood that each positioning buckle 131 is provided with a step surface 132 on the side facing the heat dissipation component 200, and each slot 212 is provided with a mating surface 213 matching the shape of the step surface 132 on the side facing the step surface 132. During installation, after the symmetrically arranged slots 212 of the heat dissipation component 200 are aligned with the symmetrically arranged positioning buckles 131 on both sides of the boss 120, the step surface 132 on the positioning buckle 131 is roughly parallel to the mating surface 213 in the slot 212. After the corresponding positioning buckle 131 is inserted into the slot 212, the step surface 132 on the positioning buckle 131 can fit with the mating surface 213 in the slot 212, thereby increasing the contact area between the positioning buckle 131 and the slot 212, making the combination between the positioning buckle 131 and the heat dissipation component 200 tighter and more stable, and enhancing the stability and reliability of the connection between the positioning buckle 131 and the heat dissipation component 200.

[0048] Reference Figure 4 and Figure 5 As shown, in the electric control box 1000 of the embodiment of the utility model, the positioning buckle 131 is formed by stamping a sheet metal part on the upper end surface of the boss 120, the positioning buckle 131 is bent to form a step surface 132, the positioning buckle 131 and the boss 120 are an integrally formed structure, and the connection between the positioning buckle 131 and the boss 120 is stable.

[0049] It is understandable that, since the boss 120 and the housing 100 are an integrally formed structure, and the positioning buckle 131 and the boss 120 are an integrally formed structure, during stamping, the boss 120 and the positioning buckle 131 can be formed on the sheet metal part only by stamping, and the production process is relatively simple, which is conducive to improving production efficiency. In addition, the positioning buckle 131 and the boss 120 do not need to be fixed by a fixing member (such as a screw, a stud, etc.), which improves the stability of the connection between the positioning buckle 131 and the boss 120, and can also reduce the number of accessories, which is conducive to reducing production costs.

[0050] It can be understood that during the stamping process, the mold is used to stamp the side of the boss 120 away from the accommodating cavity 110, so that the plate on the upper end face of the boss 120 is raised, and the upper end face of the boss 120 is punched out by the mold. One end of the plate at the punched hole is connected to the boss 120, and the other end protrudes upward to form a positioning buckle 131. The positioning buckle 131 is manufactured by sheet metal stamping, which can maximize the use of materials, reduce waste, and help reduce production costs.

[0051] Reference Figure 1 and Figure 4 As shown, it can be understood that the boss 120 and the heat dissipation component 200 are both rectangular, and there are two pairs of positioning buckles 131 and two pairs of slots 212 respectively. The two pairs of positioning buckles 131 are spaced apart on both sides of the length direction of the boss 120, and at least two pairs of slots 212 are spaced apart on both sides of the length direction of the heat dissipation component 200. The heat dissipation component 200 can be better fixed on the boss 120 by cooperating with at least two pairs of positioning buckles 131 and at least two pairs of slots 212, which is beneficial to improving the stability and reliability of the connection between the boss 120 and the heat dissipation component 200.

[0052] It is understandable that during installation, the slots 212 spaced apart on the heat dissipation assembly 200 are aligned with the positioning buckles 131 spaced apart on the boss 120, and then the corresponding positioning buckles 131 are inserted into the slots 212, so that the heat dissipation assembly 200 is positioned and fixed on the boss 120, and the entire installation process is simple and convenient.

[0053] Reference Figure 1 and Figure 4As shown, it can be understood that the number of positioning buckles 131 can be two pairs, three pairs, four pairs, etc. The number of positioning buckles 131 is not limited here. It only needs to ensure that the positioning buckles 131 can fix the heat dissipation assembly 200 on the boss 120 after cooperating with the corresponding slots 212.

[0054] It should be noted that, under the premise that the second positioning portion 211 cooperates with the first positioning portion 130 to fix the heat dissipation assembly 200 on the boss 120, the arrangement of the first positioning portion 130 on the boss 120 can be arranged according to actual needs. For example, when the number of the first positioning portions 130 is three, the three first positioning portions 130 can be arranged along the length direction of the boss 120; when the number of the first positioning portions is four, three of the first positioning portions 130 can be arranged along the length direction of the boss 120, and the other first positioning portion 130 can be arranged at both ends of the width direction of the boss 120. At this time, the four first positioning portions 130 on the boss 120 can fix the heat dissipation assembly 200 from different directions, and the fixing effect is better.

[0055] Reference Figure 3 and Figure 4 As shown, according to the electric control box 1000 of the first aspect of the utility model, the peripheral wall of the boss 120 is provided with a plurality of heat dissipation holes 121, and the plurality of heat dissipation holes 121 are distributed at intervals along the circumference of the boss 120. The heat dissipation holes 121 can connect the accommodating cavity 110 with the outside of the electric control box 1000, which is beneficial to the exchange of hot air inside the accommodating cavity 110 and external cold air, and is beneficial to improving the heat dissipation efficiency.

[0056] It should be noted that the side wall of the shell 100 may be provided with a vent 140, and the vent 140 on the side wall of the shell 100 is connected to the heat dissipation hole 121 of the boss 120. The vent 140 and the heat dissipation hole 121 cooperate to realize the convection of the gas in the accommodating cavity 110, so that the hot air in the accommodating cavity 110 can flow out from the heat dissipation hole 121 more smoothly, which is beneficial to enhance the heat dissipation effect.

[0057] It can be understood that the shape of the heat dissipation hole 121 can be square, round, etc., and the shape of the heat dissipation hole 121 is not limited herein; for example, in some embodiments, the shape of the heat dissipation hole 121 is square, and the square heat dissipation hole 121 extends from the upper part of the boss 120 to the lower part, which is beneficial to improve the exchange efficiency between the hot air inside the cavity and the external cold air, and enhance the heat dissipation effect.

[0058] Reference Figure 1 and Figure 2As shown, it can be understood that the heat dissipation assembly 200 includes a first heat sink 210 and a second heat sink 220 which are arranged relatively opposite to each other in an upper and lower manner, wherein the first heat sink 210 is in contact with the upper end surface of the boss 120, and the second heat sink 220 is connected to the electronic control board. The contact area between the first heat sink 210 and the upper end surface of the boss 120 is relatively large, which is beneficial to improving and enhancing the heat exchange efficiency between the first heat sink 210 and the boss 120; further, the second positioning portion 211 is provided on the first heat sink 210, and the second positioning portion 211 is relatively close to the first positioning portion 130, and the cooperation between the first positioning portion 130 and the second positioning portion 211 can better fix the first heat sink 210 on the upper end surface of the boss 120.

[0059] It can be understood that the second radiator 220 is connected to the electronic control board, and the first radiator 210 is arranged on the boss 120; during assembly, the first radiator 210 and the second radiator 220 are positioned by the first positioning portion 130 provided on the boss 120 to achieve rapid positioning and assembly of the heat dissipation component 200, which can not only effectively improve the assembly efficiency, but also avoid loosening and misalignment between the first radiator 210 and the second radiator 220 during the assembly process.

[0060] Reference Figure 2 , Figure 4 and Figure 5 As shown, it should be noted that each positioning buckle 131 is provided with a step surface 132 on the side facing the heat dissipation component 200, and each slot 212 is provided with a mating surface 213 that fits with the step surface 132. During installation, the step surface 132 on the positioning buckle 131 fits with the mating surface 213 in the slot 212 on the first heat sink 210, thereby increasing the contact area between the positioning buckle 131 and the slot 212, making the combination between the positioning buckle 131 and the first heat sink 210 tighter and more stable, and enhancing the stability and reliability of the connection between the positioning buckle 131 and the heat dissipation component 200.

[0061] Reference Figure 4 and Figure 5 As shown, it should be noted that the positioning buckle 131 includes a bending portion 134 and a baffle 133 extending upward, the bending portion 134 and the baffle 133 are an integrally formed structure, and the bending portion 134 and the baffle 133 form a step surface 132 on the side facing the boss 120. When the positioning buckle 131 on the boss 120 is inserted into the slot 212 of the first radiator 210, the bending portion 134 of the positioning buckle 131 fits with the mating surface 213 of the slot 212, and the baffle 133 fits with the outer wall of the first radiator 210. At this time, the fitting area between the buckle 131 and the first radiator 210 is large, which is conducive to enhancing the stability of the connection between the positioning buckle 131 and the first radiator 210.

[0062] During installation, align the slots 212 on the first radiator 210 with the positioning buckles 131 on the boss 120, and then insert the corresponding positioning buckles 131 into the slots 212. At this time, the baffle 133 also abuts against the outer wall of the first radiator 210, making the installation process simple and convenient.

[0063] It can be understood that the step surface 132 of the positioning buckle 131 fits with the mating surface 213 of the slot 212 in the first heat sink 210, and the positioning buckle 131 abuts against the outer wall of the first heat sink 210, which is beneficial to increase the total contact area between the heat dissipation assembly 200 and the boss 120, and is beneficial to improve the heat exchange efficiency between the boss 120 and the heat dissipation assembly 200.

[0064] Reference Figure 4 As shown, it should be noted that the first radiator 210 is connected to the second radiator 220 by fasteners, and the first radiator 210 and the second radiator 220 are connected to construct a channel as a mounting structure 240 for installing the refrigerant pipeline 230. It can be understood that the shape of the channel jointly constructed between the first radiator 210 and the second radiator 220 matches the shape of the refrigerant pipeline 230, and the mounting structure 240 supports, positions and protects the refrigerant pipeline 230.

[0065] Reference Figure 3 and Figure 4 As shown, in some embodiments, the first radiator 210 and the second radiator 220 are both plate structures, and are both made of heat-conducting materials, such as copper, aluminum, etc. A first groove matching the refrigerant pipeline 230 is set on the upper surface of the first radiator 210, and a second groove matching the refrigerant pipeline 230 is set on the upper and lower surfaces of the second radiator 220. The mounting structure 240 can be formed by the cooperation of the first groove and the second groove. In the embodiment, the refrigerant pipeline 230 is a round tube and has a bent pipe section formed by bending and two straight sections connected to the bent section. The bent pipe section is roughly U-shaped. The two straight sections connected to the bent section on the refrigerant pipeline 230 are both arranged in the mounting structure 240 formed by the cooperation of the first groove and the second groove, which can increase the flow path of the refrigerant in the heat dissipation component 200, which is conducive to improving the heat dissipation efficiency.

[0066] In addition, the bent section of the refrigerant pipeline 230 extends from the heat dissipation component 200 into the accommodating cavity 110 , and the bent section of the refrigerant pipeline 230 can exchange heat with the air in the accommodating cavity 110 , which is beneficial to improving the heat dissipation capacity.

[0067] It should be noted that during assembly, the straight section of the refrigerant pipeline 230 can be installed in the structure 240, which plays an effective positioning and protection role, and the installation structure 240 is stable and reliable. Of course, the curved section of the refrigerant pipeline 230 is not limited to the shape and structure of the above embodiment.

[0068] It should be noted that the electric control board is a control device, and the housing 100 can effectively protect the electric control board. Since the power module and other devices will generate a lot of heat when the electric control board is working, the heat dissipation component 200 can be used to dissipate the heat of the power module. Specifically, the second radiator 220 is directly connected to the power module, and the heat generated by the power module can be directly transferred to the second radiator 220, and the second radiator 220 exchanges heat with the refrigerant, thereby taking away the heat of the power module, playing a role in heat dissipation and cooling. The heat dissipation effect is significant, especially when the ambient temperature is high, it can effectively cool the electric control board.

[0069] It is understandable that, since the heat dissipation assembly 200 is a split structure composed of a first radiator 210 and a second radiator 220, during assembly, the second radiator 220 can be first connected and fixed to the electric control board, the first radiator 210 can be installed on the boss 120, and then the first radiator 210 can be aligned with the second radiator 220, and the first radiator 210 and the second radiator 220 can be correspondingly joined and wrapped with the refrigerant pipeline 230. It is understandable that the boss 120 supports the first radiator 210, and the height design of the boss 120 can meet the requirements that the boss 120 can support the first radiator 210 during assembly, so that the first radiator 210 and the second radiator 220 can fit together, making the structure more stable and reliable.

[0070] The air conditioner according to the embodiment of the second aspect of the utility model includes the electric control box 1000 of the embodiment of the first aspect of the utility model.

[0071] According to the air conditioner of the embodiment of the second aspect of the utility model, the shell 100 of the electric control box 1000 in the air conditioner and the boss 120 on the bottom wall of the accommodating cavity 110 are an integrally formed structure, and the heat dissipation component 200 is directly installed on the boss 120, and there is no need to separately configure a mounting bracket, which is beneficial to reducing the number of accessories and reducing production costs; during installation, the second positioning portion 211 of the heat dissipation component 200 is positioned and matched with the first positioning portion 130 on the boss 120 to position and fix the heat dissipation component 200 on the boss 120, and the refrigerant pipeline 230 is assembled on the mounting structure 240 to fix the refrigerant pipeline 230. The entire installation process is simple and convenient, and the installation efficiency is high. The heat dissipation component 200 is used to dissipate the heat of the control unit in the electric control box 1000, thereby improving the operating stability of the electric control box 1000 and improving the operating stability of the air conditioner.

[0072] According to the air conditioner of the embodiment of the second aspect of the utility model, the air conditioner includes an indoor unit and an outdoor unit connected to each other, and the electric control box 1000 is installed on the outdoor unit.

[0073] It can be understood that the electronic control box 1000 is the core control component of the air conditioner outdoor unit, which is mainly responsible for receiving and processing information from internal sensors and external control signals to accurately control the operating status of the air conditioner outdoor unit. The electronic control box 1000 is installed on the outdoor unit, and the electrical connection between the electronic control panel and the various components of the outdoor unit can be achieved using shorter wires, which is conducive to saving wire costs.

[0074] Since the air conditioner adopts all the technical solutions of the electric control box 1000 of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

[0075] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
