[0072] The following is for reference. Figures 1-17 The present invention describes an electrical control box assembly 10 and an air conditioning device 100 according to embodiments of the present invention.

[0073] Reference Figure 2 , Figure 3 and Figure 11 According to an embodiment of the present invention, the electrical control box assembly 10 includes: a box body 11, multiple power modules 12, and a terminal block 17. The box body 11 includes a main body 111 and a cover 112. The main body 111 has a mounting cavity 1111 with a mounting opening. The cover 112 is sealed to the main body 111 to cover the mounting opening. The multiple power modules 12 include a main control module 121, which is located on the cover 112 and outside the mounting cavity 1111. The remaining power modules 12 are located inside the mounting cavity 1111. (Refer to...) Figure 8The main body 111 of the box has a wiring hole 1114. The power module 12 in the mounting cavity 1111 is electrically connected to an external device through a wire harness passing through the wiring hole 1114. At least one power module 12 in the mounting cavity 1111 is electrically connected to the main control module 121. A terminal block 17 is disposed on the box 11 and located outside the mounting cavity 1111. The terminal block 17 is spaced apart from the main control module 121 and is electrically connected to at least one power module 12.

[0074] Reference Figure 5 The power module 12 located in the mounting cavity 1111 includes at least one of a filter module 122, a reactor module 123, and a module board, but this invention does not limit this. In this embodiment, most of the power modules 12 in the control box assembly 10 are disposed in the mounting cavity 1111 and protected by the box body 11, which reduces the impact of substances in the external environment on most of the power modules 12, reduces the risk of damage to most of the power modules 12, and helps to improve the service life of the control box assembly 10, that is, to improve the service life of the air conditioner.

[0075] It should be noted that the substances in the external environment can be dust, salt spray, chemicals, iron filings, water, etc., and this utility model does not limit them.

[0076] The main control module 121 is primarily used for communication with electrical devices such as sensors and drivers in the air conditioner. Considering that the main control module 121 requires user wiring, while other power modules 12 (such as filter modules or frequency converter drive modules) do not, and that the maintenance frequency of the main control module 121 is higher than that of the other power modules 12, in this embodiment, the main control module 121 is positioned outside the mounting cavity 1111 and on the cover 112. This facilitates wiring and maintenance of the main control module 121 and also improves its heat dissipation efficiency. The cover 112 serves as the mounting carrier for the main control module 121, facilitating its positioning and installation. Furthermore, by placing the main control module 121 on the cover 112, the distance between the main control module 121 and the power modules 12 located within the mounting cavity 1111 is reduced, thus facilitating electrical connection between the main control module 121 and the power modules 12 located within the mounting cavity 1111. Meanwhile, since the main control module 121 is located outside the housing 11 and the other power modules 12 are located inside the mounting cavity 1111, the main control module 121 can be spaced apart from the other power modules 12 through the housing 11. This helps to reduce the risk of electromagnetic interference between the main control module 121 and the other power modules 12 and improves the operational stability of the electrical control box assembly 10.

[0077] The terminal block 17 is mainly used for electrical connections in the circuit, serving as an electrical transition and for fixing conductors. In this embodiment of the invention, the terminal block 17 is electrically connected to at least one power module 12. Exemplarily, the terminal block 17 may be electrically connected to the power module 12 in the mounting cavity 1111, or it may be electrically connected to the main control module 121. This invention does not limit this. Positioning the terminal block 17 outside the mounting cavity 1111 facilitates its installation and wiring.

[0078] Furthermore, considering that the connection point between the terminal block 17 and the external power supply line is mainly high voltage, while the connection point of the main control module 121 is mainly low voltage, the terminal block 17 and the main control module 121 are spaced apart to facilitate the distinction between high voltage and low voltage wiring. This helps reduce the risk of accidental contact by operators and also helps prevent mutual interference between high voltage and low voltage, thereby improving the operational stability of the electrical control box assembly 10.

[0079] According to the embodiment of the present invention, the electrical control box assembly 10 has most of the power modules 12 housed in the mounting cavity 1111 and protected by the box body 11, reducing the impact of external environmental substances on the power modules 12 and lowering the risk of damage to the power modules 12. The main control module 121 and the terminal block 17 are both located outside the mounting cavity 1111, facilitating the assembly of the main control module 121 and the terminal block 17, and the electrical connection between the main control module 121 and the terminal block 17 and the power modules 12 in the mounting cavity 1111. This improves the production efficiency of the electrical control box assembly 10 and also facilitates the wiring and maintenance of the main control module 121 and the terminal block 17, increasing the installation and maintenance efficiency when the electrical control box assembly 10 is used in air conditioning. The terminal block 17 is spaced apart from the main control module 121, facilitating the differentiation of high-voltage and low-voltage wiring, reducing the risk of accidental contact by operators, and preventing mutual interference between high-voltage and low-voltage circuits, thereby improving the operational stability of the electrical control box assembly 10.

[0080] Reference Figure 1 In some application scenarios, the electrical control box assembly 10 is assembled in the air conditioning equipment 100. The air conditioning equipment 100 includes a housing 20, and the electrical control box assembly 10 is disposed inside the housing 20. The housing 20 can protect the electrical control box assembly 10 and reduce the risk of damage to the electrical control box assembly 10. Considering that the components disposed inside the housing 20 (including but not limited to the electrical control box assembly 10) may malfunction during the use of the air conditioning equipment 100, the housing 20 is provided with an inspection port 204 to facilitate maintenance personnel to inspect the components disposed inside the housing 20.

[0081] Further reference Figure 1The control box assembly 10 is positioned opposite the access port 204 to facilitate maintenance of the control box assembly 10. The side of the control box assembly 10 with the cover 112 faces the access port 204, so that the main control module 121 is positioned closer to the access port 204 than the other power modules 12, which facilitates maintenance of the main control module 121 and heat dissipation of the main control module 121.

[0082] Combination Figure 4 , Figure 11 and Figure 12 In some embodiments of the present invention, the electrical control box assembly 10 further includes a mounting box 13 for mounting the main control module 121, and the mounting box 13 is disposed on the cover 112.

[0083] For example, considering that when the main control module 121 is placed outside the housing 11, dust or rainwater and other debris may enter the housing 20 and cause the main control module 121 to malfunction, a mounting box 13 for installing the main control module 121 can be provided outside the housing 11. The mounting box 13 has a receiving cavity so that the main control module 121 can be installed in the mounting box 13. The mounting box 13 can protect the main control module 121, which helps to reduce the risk of the main control module 121 malfunctioning due to water or dust ingress and improves the operational stability of the main control module 121.

[0084] The mounting box 13 is located on the side of the box body 11 facing the inspection port 204 (i.e., on the cover 112). In other words, the mounting box 13 can be located on the side surface of the box body 11 opposite to the inspection port 204, so as to facilitate the installation of the main control module 121 on the side of the box body 11 facing the inspection port 204, which is beneficial to improving the maintenance convenience of the main control module 121.

[0085] In some embodiments of this utility model, the mounting box 13 is provided with a window for displaying the operating status of the air conditioning equipment 100 and for realizing human-computer interaction; and / or, the window is provided for the wire harness electrically connected to the main control module 121 to pass through.

[0086] In some examples, the mounting box 13 is provided with a window for displaying the operating status of the air conditioning unit 100 and for human-machine interaction. For example, when the air conditioning unit 100 malfunctions, the corresponding fault information can be displayed through the window. Users or technicians can perform targeted repairs on the air conditioning unit 100 based on the fault information displayed in the window, which helps to improve the convenience of repairing the air conditioning unit 100. In addition, during the installation, commissioning or repair of the air conditioning unit 100, technicians can adjust the parameters of the air conditioning unit 100 (such as the start threshold of the compressor 30) through this window to optimize the operating status of the air conditioning unit 100.

[0087] In other examples, the mounting box 13 is formed with a window for the wire harness that is electrically connected to the main control module 121 to pass through. The wire harness that is electrically connected to the main control module 121 can extend into the mounting box 13 through the window and be electrically connected to the main control module 121, which helps to improve the convenience of wiring the main control module 121.

[0088] In some other examples, the mounting box 13 has windows for displaying the operating status of the air conditioning equipment 100 and realizing human-machine interaction, as well as windows for the wire harness for electrical connection with the main control module 121 to pass through, so as to improve the convenience of maintenance and debugging of the air conditioning equipment 100 and improve the wiring convenience of the main control module 121.

[0089] It is understandable that the number of windows formed on the mounting box 13 and the actual application functions can be determined according to actual production requirements, and no specific limitations are made here.

[0090] Combination Figure 4 , Figure 11 and Figure 12 In some embodiments of this utility model, the window includes a display operation window 132, which is located on the side of the mounting box 13 away from the box body 11 and is used to display the operating status of the air conditioning equipment 100 and realize human-computer interaction.

[0091] For example, a receiving cavity is formed inside the mounting box 13, and the main control module 121 is disposed inside the receiving cavity. A display operation window 132 is formed on the side of the mounting box 13 opposite to the box body 11. That is, the display operation window 132 is arranged opposite to the inspection port 204, which is conducive to further improving the maintenance convenience of the air conditioning equipment 100 and the convenience of adjusting the corresponding parameters of the air conditioning equipment 100.

[0092] The window also includes a wiring port 131, which is located on the side of the mounting box 13 away from the box body 11 and below the display operation window 132. The wiring port 131 is used for the wire harness that is electrically connected to the main control module 121 to pass through. The wire harness that is electrically connected to the main control module includes, but is not limited to, the outdoor unit communication line of the air conditioning equipment, the indoor unit communication line, and various sensor lines installed on the air conditioning equipment. Users can conveniently and quickly perform wiring and cabling operations for the above-mentioned wire harness through the wiring port 131.

[0093] For example, a receiving cavity is formed inside the mounting box 13, and the main control module 121 is disposed inside the receiving cavity. Considering that the main control module 121 needs to be electrically connected to the wiring harness, a wiring port 131 is provided on the side of the mounting box 13 away from the box body 11, so that the wiring harness electrically connected to the main control module 121 can extend into the mounting box 13 to make an electrical connection with the main control module 121, which is beneficial to improving the wiring convenience of the main control module 121.

[0094] In some embodiments of this utility model, multiple wiring ports 131 are provided, at least a portion of which are provided on the side of the mounting box 13 away from the box body 11, and another portion of which are provided on other side walls of the mounting box 13.

[0095] Reference Figure 2 , Figure 11 and Figure 12 In some embodiments, the mounting box 13 includes a mounting body 133 and a flip cover 134. The mounting body 133 is connected to the cover 112. The mounting body 133 defines or participates in defining a receiving cavity for receiving the main control module 121. The receiving cavity has an opening for exposing the main control module 121. The flip cover 134 is pivotally connected to the mounting body 133 to open or close the opening.

[0096] When the main control module 121 needs to be inspected, simply rotate the flip cover 134 to open the opening and expose the main control module 121. After the inspection is completed, rotate the flip cover 134 in the opposite direction to close the opening and cover the main control module 121. The opening and closing of the mounting box 13 is simple. While ensuring the protective effect of the mounting box 13, it further reduces the convenience of the electrical control box assembly 10 inspection.

[0097] It should be noted that the cavity may be defined by the mounting body 133 alone, or the cavity may be defined by the mounting body 133 and the cover 112 together. This application does not limit this.

[0098] In some specific embodiments, the mounting body 133 is provided with a first latching part 1331, and the flip cover 134 is provided with a second latching part 1341, and the first latching part 1331 and the second latching part 1341 are engaged in a latching relationship.

[0099] In this embodiment of the utility model, the stability of the flip cover 134 when the opening is closed is improved. Only after manually releasing the latching engagement of the first latch 1331 and the second latch 1341 can the mounting box 13 be rotated to open the opening and expose the main control module 121, which effectively ensures the protective effect of the mounting box 13.

[0100] In some specific embodiments of this utility model, the mounting box 13 includes a mounting body 133 and a flip cover 134, the flip cover 134 being rotatably disposed on the mounting body 133 and positioned and engaged with the mounting body 133.

[0101] For example, the mounting body 133 is located on the side of the cover 112 away from the mounting cavity 1111, and the mounting body 133 can serve as the mounting carrier for the main control module 121 to position and support the main control module 121. The flip cover 134 has a wiring port 131 and a display operation window 132, and the flip cover 134 can be rotatably connected to the mounting body 133 via a pivot. When the main control module 121 is wired, the flip cover 134 can be driven to rotate relative to the mounting body 133 to expose the main control module 121 mounted on the mounting body 133, thereby facilitating the wiring of the main control module 121.

[0102] After the main control module 121 is wired, the flip cover 134 can be driven to reset, so that the flip cover 134 can at least partially cover the main control module 121, thereby reducing the risk of operators accidentally touching the live components on the main control module 121.

[0103] The mounting body 133 is provided with a first latching part 1331, and the flip cover 134 is provided with a second latching part 1341. The first latching part 1331 and the second latching part 1341 are engaged in a latching action.

[0104] The flip cover 134 can be further engaged with the mounting body 133 to improve the reliability of the engagement between the flip cover 134 and the mounting body 133, thereby helping to ensure the reliability of the flip cover 134 in at least partially covering the main control module 121.

[0105] In some embodiments, the mounting body 133 is constructed as a cylindrical structure with openings at both ends. The cover 112 closes the opening of the mounting body 133 facing the box 11. When the flip cover 134 is in the closed state, the mounting box 13 protects the main control module 121 inside itself. When the flip cover 134 is in the open state, the main control module 121 is exposed to facilitate maintenance by operators.

[0106] Furthermore, referring to Figure 4 , Figure 14 and Figure 15 The electrical control box assembly 10 also includes a first connecting component 105, which is used to fix the cover 112 and the main control module 121. Fasteners first pass through a portion of the mounting body 133, then through the main control module 121, and connect to the first connecting component 105, thereby installing the mounting box 13 and the main control module 121 onto the cover 112. Simultaneously, the cover 112 closes the opening of the mounting body 133 facing the box 11. In this embodiment of the invention, the installation method of the mounting box 13 and the main control module 121 is simple, further improving the assembly efficiency of the electrical control box assembly 10.

[0107] In other examples, the mounting body 133 and the cover 112 are integrally formed, which helps to further simplify the assembly process of the electrical control box assembly 10, thereby improving the assembly efficiency of the electrical control box assembly 10.

[0108] Reference Figure 4 , Figure 14 and Figure 15 In some embodiments, a portion of the cover 112 extends toward the side away from the box body 111 to form a boss 1123, on which the main control module 121 is mounted.

[0109] In this embodiment of the application, by providing a boss 1123 on the cover 112, it is beneficial to improve the strength of the cover 112, facilitate the installation of the main control module 121 on the cover 112, and improve the stability of the connection between the main control module 121 and the cover 112; and the boss 1123 protrudes outward, which further improves the convenience of installing and wiring the main control module 121.

[0110] In some embodiments of this utility model, the electrical control box assembly 10 further includes a first connecting assembly 105, which is used to fix the cover 112 and the main control module 121 to improve the installation reliability of the main control module 121.

[0111] At least a portion of the first connecting component 105 is located on the side of the cover 112 opposite to the box body 111, and the first connecting component 105 is integrally formed with the cover 112. In other embodiments, the first connecting component 105 may pass through the cover 112, and the first connecting component 105 and the cover 112 may be sealed together.

[0112] Whether the first connecting component 105 and the cover 112 are integrally formed or the first connecting component 105 and the cover 112 are sealed together, external dust, liquids and other debris can be prevented from entering the mounting cavity 1111 through the connection between the first connecting component 105 and the cover 112, effectively improving the sealing performance of the cover 112 and enhancing the reliability of the protection provided by the box 11.

[0113] In some specific embodiments, the first connecting component 105 includes a plurality of press-fit studs disposed on the cover 112.

[0114] Press-fit studs are fasteners used to connect thin-walled workpieces or hollow profiles. They are fixed to the cover 112 by riveting, preventing liquids and gases from entering the mounting point and improving the sealing effect of the cover 112. Furthermore, the connection method between the press-fit studs and the cover 112 is simple, further reducing the cost of the electrical control box assembly 10.

[0115] In some specific embodiments, the first connecting component 105 includes four press-fit studs, which are rectangularly distributed on the boss 1123. Fasteners pass through the main control module 121 and are threadedly engaged with the press-fit studs to fix the main control module 121 to the cover 112.

[0116] It should be understood that the number of press-fit studs is not limited to four, and can also be two, three, six or other numbers; the structure of the first connecting component 105 is not limited to press-fit studs, and can also be a hook, and the main control module 121 can also be fixed to the cover 112 by snap-fit, adhesive or other means, and this utility model does not limit this.

[0117] Reference Figure 5 In some other embodiments of this utility model, the power module 12 may include a frequency converter drive module 124, a main control module 121, a filter module 122, and a reactor module 123. The main control module 121 is disposed on the cover and located outside the mounting cavity 1111. The frequency converter drive module 124, the filter module 122, and the reactor module 123 are all disposed inside the mounting cavity 1111. The main control module 121 is disposed closer to the maintenance port 204 than the frequency converter drive module 124, the filter module 122, and the reactor module 123, so as to facilitate the maintenance and wiring of the main control module 121.

[0118] Combination Figure 5 and Figure 6 In some embodiments of this utility model, the box body 11 is provided with a medium flow channel 115 for containing the heat exchange medium. The medium flow channel 115 is used to exchange heat with the heating element inside the box body 11 to dissipate heat from it.

[0119] It should be noted that the "heating element" can be a component that is installed on the circuit board of the power module 12 and generates heat when it is working; or it can be a component that is independent of the power module 12 but electrically connected to the power module 12 and generates heat when it is working.

[0120] For example, the heat exchange medium can flow in the medium flow channel 115, and during the flow of the heat exchange medium in the medium flow channel 115, it can transfer heat to the flow channel wall of the medium flow channel 115, so as to exchange heat with the heating element in the box 11 through the medium flow channel 115, thereby dissipating heat from the heating element, reducing the risk of failure of the electrical control box assembly 10 due to overheating of the heating element, and improving the safety of the use of the electrical control box assembly 10.

[0121] In some examples, the medium flow channel 115 is provided with an inlet pipe 1151 and an outlet pipe 1152, and the inlet pipe 1151 and the outlet pipe 1152 can be connected to the refrigerant circulation system of the air conditioning equipment 100, for example, the inlet pipe 1151 and the outlet pipe 1152 can be connected to the compressor 30 described below, and the heat exchange medium in the refrigerant circulation system can enter the medium flow channel 115 to dissipate heat from the heating element in the housing 11.

[0122] Optionally, the heat exchange medium can be configured as a phase change material, which is beneficial to improving the heat exchange performance of the heat exchange medium; it is understood that the specific material of the heat exchange medium can be determined according to the actual production requirements, and no specific limitation is made here.

[0123] It is understandable that the shape of the medium flow channel can be designed according to the arrangement of the heating elements inside the box, as long as the heating elements with large heat output can exchange heat with the medium flow channel, no specific limitation is made here.

[0124] like Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments of this utility model, the power module further includes a filter module 122, which is disposed inside the housing 11, and the heating element disposed on the filter module 122 is disposed toward the medium flow channel 115.

[0125] For example, considering that the filter module 122 has high requirements for waterproofing, the filter module 122 can be placed inside the housing 11 so that the housing 11 can protect the filter module 122 and reduce the risk of the filter module 122 malfunctioning due to contact with water.

[0126] The filter module 122 is used to filter out noise signals and electromagnetic interference in the circuit to ensure the operational stability of the electronic control box assembly 10. Specifically, it combines... Figure 13 and Figure 16 A high-heat-generating element (such as a common-mode inductor 1221) is provided on one side of the filter module 122. When the control box assembly 10 is working, the heating element will generate a lot of heat. In order to improve the heat dissipation effect of the heating element, the heating element can be placed on the side of the filter module 122 opposite to the medium flow channel 115 to reduce the distance between the heating element and the medium flow channel 115. This facilitates radiative heat exchange between the heating element and the medium flow channel 115, which is beneficial to improving the heat exchange effect and efficiency between the medium flow channel 115 and the heating element. This is beneficial to improving the heat dissipation effect of the heating element and reducing the risk of overheating of the heating element.

[0127] Combination Figure 4 and Figure 8In some embodiments of this utility model, the box body 11 includes: a box body 111 and a cover 112. The box body 111 has an installation cavity 1111 that opens toward the inspection port 204. Part of the power module 12 is located in the installation cavity 1111. The box body 111 is provided with a wire hole 1114. The wire harness connected to the power module 12 passes through the wire hole 1114 and is electrically connected to the external device. The cover 112 is placed on the open end of the box body 111 to seal the open end.

[0128] For example, components that need to be housed in the housing 11 (such as power module 12 and filter module 122) can be installed into the mounting cavity 1111 through the open end of the housing 111. The cover 112 can be placed on the open end of the housing 1111 to cover the mounting cavity 1111, thereby improving the sealing of the mounting cavity 1111 and reducing the risk of dust or rainwater and other debris entering the mounting cavity 1111, which is beneficial to improving the operational stability of the electrical control box assembly 10.

[0129] Furthermore, referring to Figure 5 and Figure 8 Part of the power module 12 is located within the mounting cavity 1111. For example, the power module 12 may include a frequency converter drive module 124. The frequency converter drive module 124 is located within the mounting cavity 1111, and the frequency converter drive module 124 needs to be electrically connected to external equipment (e.g., compressor 30 or fan) via a wiring harness. Considering the wiring requirements of the frequency converter drive module 124, a wire through hole 1114 can be provided on the main body 111 so that the wiring harness connected to the frequency converter drive module 124 can pass through the wire through hole 1114 to be electrically connected to the external equipment. This improves the wiring convenience of the power module 12.

[0130] Furthermore, the cover 112 is movably sealed over the open end of the box body 111 to facilitate the maintenance of components located in the mounting cavity 1111. By setting the wiring hole on the box body 111, the wiring harness connected to the power module 12 can be passed through the box body 111. Alternatively, the wiring harness connected to the power module 12 can avoid the cover 112. When it is necessary to remove the cover 112 from the box body 111, interference from the wiring harness connecting the power module 12 and the external device can be avoided, which would prevent the cover 112 from exposing the open end of the box body 111, thus avoiding affecting the maintenance efficiency of the electrical control box assembly 10. At the same time, it helps to prevent the cover 112 from moving the wiring harness during the process of removing the cover 112 from the box body 111, thus affecting the reliability of the electrical connection.

[0131] Reference Figure 2 , Figure 11 and Figure 12In some embodiments of the present invention, the electrical control box assembly 10 further includes a mounting box 13 for mounting the main control module 121, the mounting box 13 being disposed on the side of the cover 112 facing the inspection port 204.

[0132] For example, the mounting box 13 has a receiving cavity, the main control module 121 is disposed in the receiving cavity, and the mounting box 13 is disposed on the side surface of the cover 112 opposite to the receiving cavity, so that one of the cover 112 or the mounting box 13 can be selectively opened according to the maintenance needs of the electrical control box assembly 10, which helps to reduce the maintenance difficulty of the electrical control box assembly 10. For example, when the main control module 121 needs to be maintained, only the mounting box 13 can be opened without opening the box 11, thereby reducing the impact on the sealing effect of the box 11 due to frequent opening of the box 11.

[0133] In some embodiments of the present invention, the electrical control box assembly 10 further includes a terminal block 17, which is disposed outside the box body 11 and located at the lower part of the box body 11. The terminal block 17 is spaced apart from the mounting box 13. The terminal block 17 is used to connect an external power supply line and is electrically connected to at least one power module 12.

[0134] It should be noted that "external power cord" refers to the client's power cord. The specific directions for "up" and "down" can be found in the diagram. Figure 4 As shown.

[0135] For example, the terminal block 17 is mainly used for electrical connection in the circuit, serves as an electrical transition and is used to fix the wire harness. The terminal block 17 can be electrically connected to the power module 12 in the mounting cavity 1111, or the terminal block 17 can be electrically connected to the main control module 121.

[0136] The mounting box 13 can be located on the upper part of the box body 11, and the terminal block 17 can be located on the lower part of the box body 11. For example, the mounting box 13 can be located on the upper part of the cover 112, and the terminal block 17 can be located on the side surface of the box body 11 that is perpendicular to the access port 204 and located lower. For example, the terminal block 17 can be located on the third plate 3 described below, or on the part of the first plate 1 described below that is close to the third plate 3, so that when the cover 112 is opened, there is no need to disassemble or pull the external power cord, which is beneficial to improving the reliability of the electrical connection of the electrical control box assembly 10; or the mounting box 13 can be located on the upper part of the cover 112, and the terminal block 17 can be located on the lower part of the cover 112, so as to reduce the vertical dimension of the electrical control box assembly 10, thereby reducing the space required to arrange the electrical control box assembly 10.

[0137] By placing the terminal block 17 at the lower part of the housing 11, it facilitates the routing of external power lines, thereby making it easier to connect the terminal block 17 to the external power line. In addition, considering that the connection point between the terminal block 17 and the external power line is mainly high voltage, while the connection point of the main control module 121 located in the mounting box 13 is mainly low voltage, the terminal block 17 and the mounting box 13 are spaced apart to distinguish between high voltage and low voltage wiring. This helps reduce the risk of accidental contact by operators and also helps prevent mutual interference between high voltage and low voltage, thereby improving the operational stability of the electrical control box assembly 10.

[0138] Reference Figure 12 , Figure 14 and Figure 15 In some embodiments, the housing 11 is provided with a first mounting surface 1101 and a second mounting surface 1102, the first mounting surface 1101 and the second mounting surface 1102 are arranged side by side, the terminal block 17 is disposed on the first mounting surface 1101, and the main control module 121 is disposed on the second mounting surface 1102.

[0139] In some application scenarios, the electrical control box assembly 10 is arranged opposite to the maintenance port 204 to facilitate the maintenance of the electrical control box assembly 10. The electrical control box assembly 10 is arranged with one side of the first mounting surface 1101 and the second mounting surface 1102 facing the maintenance port 204, so that the main control module 121 and the terminal block 17 are both arranged close to the maintenance port 204 to facilitate the maintenance of the main control module 121 and the terminal block 17.

[0140] In this embodiment, the terminal block 17 is disposed on the first mounting surface 1101, and the main control module 121 is disposed on the second mounting surface 1102. The first mounting surface 1101 and the second mounting surface 1102 are arranged side by side, which further improves the convenience of installation, wiring and maintenance of the terminal block 17 and the main control module, and improves the convenience of maintenance of the electrical control box assembly 10.

[0141] In some embodiments of this utility model, the terminal block 17 is disposed on the cover 112.

[0142] For example, the terminal block 17 is disposed on the side of the cover 112 opposite to the mounting cavity 1111 to facilitate the installation of the terminal block 17, and at the same time to reduce the distance between the terminal block 17 and the power module 12 disposed in the mounting cavity 1111, thereby facilitating the electrical connection between the terminal block 17 and the power module 12 disposed in the mounting cavity 1111.

[0143] In this embodiment, the terminal block 17 is directly disposed on the cover 112, without the need for other structures for mounting the terminal block 17, thereby reducing the vertical dimension of the electrical control box assembly 10 and thus reducing the space required for arranging the electrical control box assembly 10.

[0144] In some embodiments of this utility model, the electrical control box assembly 10 further includes a second connecting assembly 106, which is used to fix the cover 112 and the terminal block 17, thereby improving the reliability of the installation of the terminal block 17.

[0145] The second connecting component 106 is integrally formed with the cover 112. In other embodiments, the second connecting component 106 may pass through the cover 112, and the second connecting component 106 and the cover 112 may be sealed together.

[0146] Whether the second connecting component 106 is integrally formed with the cover 112 or the second connecting component 106 is sealed to the cover 112, it can prevent dust, liquid and other debris from entering the mounting cavity 1111 through the connection between the second connecting component 106 and the cover 112, effectively improving the sealing performance of the cover 112 and the reliability of the protection of the box 11.

[0147] In some specific embodiments, the second connecting component 106 includes a plurality of blind hole rivet nuts disposed on the cover 112.

[0148] Blind hole rivet nuts are fasteners specifically designed for single-sided mounting scenarios, used to create high-strength internal threaded connections in enclosed cavities, thin-walled materials, or workpieces that cannot be accessed from the back. Furthermore, the connection method between the rivet nut and the cover 112 is simple, further reducing the cost of the electrical control box assembly 10.

[0149] In some specific embodiments, the second connecting component 106 includes: two blind hole rivet nuts, which are spaced apart on the first mounting surface 1101; and fasteners pass through the terminal block 17 and are threadedly engaged with the blind hole rivet nuts to fix the terminal block 17 to the cover 112.

[0150] It should be understood that the number of blind hole rivet nuts is not limited to two, and can also be three, four, six or other numbers; the second connecting component 106 is not limited to blind hole rivet nuts, and can also be a hook, and the terminal block 17 can also be fixed to the cover by snap-fit, adhesive or other means, and this utility model does not limit this.

[0151] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments of this utility model, the housing 11 further includes a mounting plate 1115. The mounting plate 1115 is connected to the housing body 111 and located outside the mounting cavity 1111. The mounting plate 1115 is adapted to avoid the installation and removal of the cover 112. The terminal block 17 is disposed on the mounting plate 1115 so that when the cover 112 is opened, it is not necessary to disassemble or pull the external power cord, which helps to improve the reliability of the electrical connection of the electrical control box assembly 10.

[0152] In some embodiments, the mounting plate 1115 is provided with a first mounting surface 1101 for mounting the terminal block 17, and the cover 112 is provided with a second mounting surface 1102 for mounting the main control module 121. The first mounting surface 1101 and the second mounting surface 1102 are arranged side by side.

[0153] In some application scenarios, the electrical control box assembly 10 is arranged opposite to the maintenance port 204 to facilitate the maintenance of the electrical control box assembly 10. The electrical control box assembly 10 is arranged with one side of the first mounting surface 1101 and the second mounting surface 1102 facing the maintenance port 204, so that the main control module 121 and the terminal block 17 are both arranged close to the maintenance port 204 to facilitate the maintenance of the main control module 121 and the terminal block 17.

[0154] In this embodiment, the terminal block 17 is disposed on the first mounting surface 1101, and the main control module 121 is disposed on the second mounting surface 1102. The first mounting surface 1101 and the second mounting surface 1102 are arranged side by side, which further improves the convenience of installing, wiring, and maintaining the terminal block 17 and the main control module, and improves the convenience of maintaining the electrical control box assembly 10.

[0155] In some specific embodiments, the mounting plate 1115 may be disposed on the third plate 3 described below, or on the portion of the first plate 1 near the third plate 3 described below, and this application does not limit this.

[0156] In some further embodiments, the mounting plate 1115 may be positioned near the cover 112 on the box body 111 to reduce the distance between the first mounting surface 1101 and the second mounting surface 1102 in the thickness direction of the box body 11, thereby further improving the convenience of installing, wiring, and maintaining the terminal block 17 and the main control module, and improving the convenience of maintaining the electrical control box assembly 10.

[0157] In some embodiments of this utility model, the terminal block 17 is disposed on the housing 11, and a protective cover 171 is provided on the terminal block 17. The protective cover 171 is movably disposed on the housing 11 to cover or expose the terminal block 17.

[0158] The external power cord is connected to the terminal block 17. The protective cover 171 can be placed on the side of the terminal block 17 away from the cover 112 to block the connection between the terminal block 17 and the external power cord, reduce the risk of operators accidentally touching high voltage, and improve the safety of the electrical control box assembly 10. When it is necessary to expose the terminal block 17, the protective cover 171 can be driven to move relative to the cover 112 so that the protective cover 171 can expose the terminal block 17.

[0159] In some examples, the protective cover 171 is detachably mounted on the housing 11; in other examples, the protective cover 171 is rotatably mounted on the housing 11. It is understood that the specific mode of operation of the protective cover 171 can be determined according to actual production requirements, and no specific limitation is made here.

[0160] In some embodiments, the protective cover 171 is configured as an insulating plastic cover.

[0161] In some embodiments of this utility model, the electrical control box assembly 10 further includes a wire clamp 18, which is located at the lower part of the terminal block 17. The external power cord can be supported and fixed by the wire clamp 18 to reduce the risk of the external power cord becoming loose or falling off, thereby improving the reliability of the electrical connection of the electrical control box assembly 10.

[0162] Combination Figure 5 , Figure 6 and Figure 7 In some embodiments of this utility model, the box body 111 is provided with a medium flow channel 115 for accommodating the heat exchange medium, the power module 12 includes a filter module 122, the filter module 122 is located in the mounting cavity 1111, and the heating element provided on the filter module 122 is arranged facing the medium flow channel 115. The power module 12 also includes a reactor module 123, the reactor module 123 is located in the mounting cavity 1111 and is attached to the box body 111.

[0163] For example, when the electrical control box assembly 10 is working, the heating element will generate heat. In order to improve the heat dissipation effect of the heating element, the heating element can be set on the side opposite to the filter module 122 and the medium flow channel 115, so that radiative heat exchange can be achieved between the heating element and the medium flow channel 115. This also helps to reduce the distance between the heating element and the medium flow channel 115, improve the heat exchange effect and heat exchange efficiency between the medium flow channel 115 and the heating element, thereby improving the heat dissipation effect of the heating element and reducing the risk of overheating of the heating element.

[0164] By fitting the reactor module 123 into the housing body 111, it is beneficial to fit the reactor module 123 into the medium flow channel 115 provided on the housing body 111. This allows the reactor module 123 and the medium flow channel 115 to exchange heat through contact, which is beneficial to further improve the heat dissipation effect of the reactor module 123 and reduce the risk of overheating of the reactor module 123.

[0165] In some embodiments of this utility model, the reactor module 123 is thermally connected to the back plate 1112.

[0166] For example, the reactor module 123 can be thermally connected to the backplate 1112 by setting a thermally conductive silicon steel sheet, thermally conductive silicone, or by making the reactor module 123 directly contact the backplate, so that the medium flow channel 115 can exchange heat with the heat-generating element of the reactor module 123 and improve the heat dissipation effect of the reactor module 123.

[0167] The heating element of the reactor module can be a coil.

[0168] Reference Figure 5 In some embodiments of this utility model, the filter module 122 and the reactor module 123 are arranged side by side in the width direction of the housing 11.

[0169] For example, the filter module 122 can be disposed in the upper left part of the mounting cavity 1111, and the reactor module 123 can be disposed in the upper right part of the mounting cavity 1111. Since the reactor module 123 is small in size, by arranging the filter module 122 and the reactor module 123 in the width direction of the box 11, it is beneficial to reduce the size of the electrical control box assembly 10 in the width direction, thereby reducing the space required to arrange the electrical control box assembly 10.

[0170] In some embodiments of this utility model, the power module 12 further includes a frequency conversion drive module 124, which is spaced apart from the filter module 122, and the circuit board 1241 of the frequency conversion drive module 124 is disposed facing the medium flow channel 115.

[0171] For example, the frequency converter drive module 124 can be disposed in the lower part of the mounting cavity 1111, and the filter module 122 can be disposed in the upper part of the mounting cavity 1111, so as to realize that the frequency converter drive module 124 and the filter module 122 are spaced apart, which is beneficial to suppress electromagnetic interference between the frequency converter drive module 124 and the filter module 122, and facilitates heat dissipation of the frequency converter drive module 124 and the filter module 122 respectively.

[0172] Reference Figure 5 , Figure 6 and Figure 7 The circuit board 1241 of the frequency converter drive module 124 is disposed facing the medium flow channel 115. For example, the medium flow channel 115 can be disposed on the back plate 1112 described below, and the circuit board 1241 can be disposed facing the back plate 1112 so that the back plate 1112 can support the circuit board 1241, thereby improving the assembly reliability of the frequency converter drive module 124. At the same time, it is convenient for the medium flow channel 115 to exchange heat with the heat-generating elements disposed on the circuit board 1241 through the circuit board 1241, thereby improving the heat dissipation effect of the frequency converter drive module 124.

[0173] It should be noted that, as Figure 17As shown, the heating element of the variable frequency drive module 124 can be a fan drive module 1242, a compressor drive module 1243, a non-inductive resistor 1244, an electrolytic capacitor 1245, etc.

[0174] Reference Figure 5 , Figure 6 and Figure 7 In some embodiments of this utility model, the frequency conversion drive module 124 and the filter module 122 are arranged side by side in the height direction of the housing 11.

[0175] For example, the filter module 122 can be disposed in the mounting cavity 1111 and located at the upper part of the mounting cavity 1111, and the frequency converter drive module 124 can be disposed in the mounting cavity 1111 and located below the filter module 122. Thus, by arranging the filter module 122 and the reactor module 123 side by side in the width direction of the housing 11, it is beneficial to reduce the height dimension of the control box assembly 10. By further arranging the frequency converter drive module 124 and the filter module 122 side by side in the height direction of the housing 11, a flat design of multiple power modules 12 in the mounting cavity 1111 can be achieved, which is beneficial to reduce the dimension of the control box assembly 10 in the thickness direction, thereby facilitating the miniaturization design of the control box assembly 10, and further reducing the arrangement space required for the control box assembly 10, so as to increase the space in the housing 20 for arranging the refrigerant circulation system.

[0176] like Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the electrical control box assembly 10 further includes a first sealing member 14, which is disposed between the box body 111 and the cover 112 to make the box body 111 and the cover 112 seal together.

[0177] For example, the first sealing member 14 can be sandwiched between the open end of the box body 111 and the cover 112. When the cover 112 is placed over the open end of the box body 111, the first sealing member 14 can play a sealing role between the cover 112 and the box body 111, thereby improving the sealing performance of the box body 11 and preventing dust or rainwater and other debris from entering the box body 11 due to gaps between the cover 112 and the box body 111. This helps to reduce the risk of failure of the electrical control box assembly 10 and improve the service life of the electrical control box assembly 10.

[0178] In some examples, the first seal 14 can be constructed as a sealing ring.

[0179] Combination Figure 4 and Figure 8In some embodiments of this utility model, the box body 111 includes a back plate 1112 and a side plate 1113. The back plate 1112 is used to install at least part of the power module 12. The side plate 1113 is arranged around the back plate 1112 in the circumferential direction and together with the back plate 1112 defines the mounting cavity 1111. The side plate 1113 is provided with a wire hole 1114.

[0180] For example, the side panel 1113 is disposed around the back panel 1112 in the circumferential direction, and the side panel 1113 extends along the back panel 1112 toward the access port 204, so that the side panel 1113 and the back panel 1112 can jointly define a mounting cavity 1111 open toward the access port 204. The back panel 1112 is used to mount at least part of the power module 12, such as the frequency converter drive module 124, which can be mounted on the back panel 1112. The back panel 1112 may be provided with a medium flow channel 115 to facilitate heat exchange with the power module 12 disposed on the back panel 1112 and to improve the heat exchange efficiency of the power module 12.

[0181] The side panel 1113 is provided with a wire hole 1114 so that the wire harness connected to the power module 12 or filter module 122 and other components located in the box body 11 can pass through the wire hole and pass through the side panel 1113. This allows the wire harness to avoid the cover 112, preventing the cover 112 from interfering with the open end of the box body 111 and thus avoiding affecting the maintenance efficiency of the electrical control box assembly 10. At the same time, it helps to prevent the cover 112 from moving the wire harness during the process of removing the cover 112 from the box body 111, which would affect the reliability of the electrical connection. In addition, placing the wire hole on the side panel 1113 can prevent the wire hole from occupying the space on the back panel 1112 used for arranging the medium flow channel 115, which helps to increase the arrangement area of ​​the medium flow channel 115, thereby improving the heat dissipation effect of the medium flow channel 115 on the heat-generating components.

[0182] In some embodiments of this utility model, the back plate 1112 and the side plate 1113 are formed as one piece, and both the back plate 1112 and the side plate 1113 are provided with a medium flow channel 115.

[0183] The box body 111 is formed by the back plate 1112 and the side plate 1113. Both the back plate 1112 and the side plate 1113 are provided with medium flow channels 115. Both the back plate 1112 and the side plate 1113 can be used to generate heat, not limited to traditional unidirectional heat dissipation. The main box body 11 is constructed as a box-shaped heat sink, which can receive the heat dissipated by the power module 12 from multiple directions such as the bottom and the circumference, forming multi-directional radiative heat dissipation. The back plate 1112 and the side plate 1113 work together to maximize the space and direction of radiative heat dissipation. The heat generated by the power module 12 can be quickly diffused to either the back plate 1112 or the side plate 1113, realizing rapid air cooling in the mounting cavity 1111 and uniformly reducing the temperature in all parts of the mounting cavity 1111. Meanwhile, both the back panel 1112 and the side panel 1113 are located on the outer layer. The side panel 1113 surrounds the power module 12. The side panel 1113 is directly installed in the thickness direction of the back panel 1112 using the assembly space of the power module 12 for heat dissipation. The side panel 1113 and the back panel 1112 together form a box to accommodate the power module 12, eliminating the need for additional installation space. This greatly simplifies the structure of the control box assembly 10 and is more conducive to the miniaturization design of the control box assembly 10.

[0184] For example, both the back panel 1112 and the side panel 1113 are provided with medium flow channels 115. The medium flow channels 115 can form a surrounding heat dissipation for the power module disposed in the mounting cavity 1111, so as to quickly dissipate the hot air generated in the mounting cavity 1111 due to the heat generated by the power module 12, which is beneficial to improving the heat dissipation efficiency of the power module 12.

[0185] Combination Figure 8 , Figure 10 and Figure 13 In some embodiments of this utility model, the electrical control box assembly 10 further includes a second sealing member 15, which is disposed in the wire hole 1114 and is used for the wire harness connected to the power module 12 to pass through.

[0186] For example, considering that the wiring hole 1114 is connected to the mounting cavity 1111, if the wire harness connected to the power module 12 passes through the wiring hole 1114 and there is a gap between the wire harness and the wiring hole 1114, dust or rainwater and other debris may enter the housing 11 through the gap between the wire harness and the wiring hole 1114, thereby affecting the operational stability and service life of the electrical control box assembly 10. Therefore, a second sealing element 15 is provided at the wiring hole 1114. The wire harness connected to the power module 12 can pass through the second sealing element 15 and the wiring hole. The second sealing element 15 can seal the gap between the wire harness and the wiring hole to further improve the sealing performance of the housing 11, so that the housing 11 can achieve the IP67 protection level. That is to say, the housing 11 can meet the waterproof and dustproof requirements of the IP67 standard, providing reliable protection for the components installed in the housing 11.

[0187] In other embodiments, the wiring harness connected to the power module 12 is adapted to be electrically connected to the power module 12 via the second seal 15.

[0188] In other words, the power module 12 and the wiring harness connected to the power module 12 can be electrically connected to the second sealing member 15 respectively. While realizing the electrical connection between the power module 12 and the wiring harness connected to the power module 12, the second sealing member 15 can effectively improve the sealing performance at the wire hole 1114, prevent dust or rainwater and other debris from entering the box 11 and affecting the operational stability of the electrical control box assembly 10, and help improve the service life of the electrical control box assembly 10.

[0189] Reference Figure 4 , Figure 8 and Figure 10 It is understood that the power module 12 may include a filter module 122, a reactor module 123 and a frequency conversion drive module 124, etc. The wiring harness connecting the power module 12 and the external device can be provided with corresponding wire holes 1114, and a second sealing element 15 is provided at each wire hole 1114 to improve the sealing performance of the box 11.

[0190] Therefore, by setting the first sealing element 14 and the second sealing element 15, the sealing performance of the box body 11 is ensured, so that the mounting cavity 1111 can be formed into a sealed chamber, ensuring the protective effect of the box body 11 on the filter module 122 and the frequency conversion drive module 124, and avoiding the failure of the electrical control box assembly 10 due to water and dust entering the box body 11.

[0191] In some embodiments of this utility model, the second sealing member 15 includes: a first sealing part 151, a second sealing part 152, and a third sealing part 153. The first sealing part 151 is disposed on the first plate 1 of the side panel 1113 and is used to electrically connect the compressor line 101 to the power module 12. The second sealing part 152 is disposed on the second plate 2 of the side panel 1113 and is used to electrically connect the power supply line 102 to the power module 12. The third sealing part 153 is disposed on the third plate 3 of the side panel 1113 and is used to electrically connect the fan line 103 to the power module 12. The second plate 2 and the third plate 3 are arranged opposite each other in the vertical direction (which can also be understood as the height direction of the electrical control box assembly 10). The first plate 1 is disposed at one end of the second plate 2 and the third plate 3 and is connected to the second plate 2 and the third plate 3 respectively.

[0192] For example, the side panel 1113 includes a second panel 2 and a third panel 3 that are vertically opposite to each other and arranged above the third panel 3. The side panel 1113 also includes a first panel 1 that extends vertically and connects the second panel 2 and the third panel 3. The first panel 1 is located at the left end of the second panel 2 and the third panel 3.

[0193] The first plate 1 is provided with a first sealing part 151, which is located close to the third plate 3 in the vertical direction to reduce the distance between the first sealing part 151 and the compressor 30. The compressor line 101 can extend into the box 11 through the first sealing part 151 and be electrically connected to the frequency converter drive module 124, which helps to shorten the length of the compressor line 101 and reduce the cost of electrical connection of the electrical control box assembly 10.

[0194] The power supply line 102 is electrically connected to the external power supply line through the terminal block 17 and is used to supply power to the filter module 122. The second plate 2 is provided with a second sealing part 152. The power supply line 102 can be electrically connected to the filter module 122 through the second sealing part 152. By setting the second sealing part 152 on the second plate 2, the distance between the second sealing part 152 and the filter module 122 is reduced, thereby facilitating the electrical connection of the power supply line 102.

[0195] The third sealing part 153 is located on the side of the third plate 3 away from the first plate 1. The fan line 103 can extend into the box 11 through the third sealing part 153 and be electrically connected to the frequency converter drive module 124. This arrangement can prevent the large width space required for arranging the electrical control box assembly 10 due to the fact that both the fan line 103 and the compressor line 101 are arranged along the width direction of the box 11. In other words, in the width direction of the electrical control box assembly 10, it is beneficial to save the space required for arranging the electrical control box assembly 10, thereby reducing the size of the air conditioning equipment 100 in the width direction of the electrical control box assembly 10 and facilitating the miniaturization design of the air conditioning equipment 100.

[0196] In some examples, the communication line 104 can also extend into the housing 11 through the third sealing part 153 and be electrically connected to the frequency converter drive module 124. The frequency converter drive module 124 can receive signals through the communication line 104, and the frequency converter drive module 124 can regulate the compressor 30 and the fan respectively through the compressor line 101 and the fan line 103 according to the received signals.

[0197] In some embodiments of this utility model, the inlet pipe 1151 and the outlet pipe 1152 are located at the lower part of the box body 11, so that the inlet pipe 1151 and the outlet pipe 1152 can be misaligned with the compressor line 101, and the compressor line 101 can avoid the inlet pipe 1151 and the outlet pipe 1152, so as to ensure that the inlet pipe 1151 and the outlet pipe 1152 have sufficient installation space, which is beneficial to improving the assembly convenience of the electrical control box assembly 10.

[0198] In some examples, the inlet pipe 1151 and the outlet pipe 1152 can be fixed to the housing 11 by welding to improve the assembly reliability of the inlet pipe 1151 and the outlet pipe 1152.

[0199] Reference Figure 9 In some embodiments of this utility model, a heat-conducting plate 19 is provided inside the box body 11, and multiple power modules 12 are respectively heat-conductingly connected to the back plate 1112 through the heat-conducting plate 19.

[0200] For example, a plurality of heat-conducting plates 19 are provided on the side of the back plate 1112 facing the mounting cavity 1111. Power modules 12 such as the filter module 122 and the frequency conversion drive module 124 can be thermally connected to the back plate 1112 through the heat-conducting plates 19, which is beneficial to improving the heat exchange effect between the power module 12 and the medium flow channel 115, thereby reducing the risk of overheating of the electrical control box assembly 10 and improving the safety of the electrical control box assembly 10.

[0201] In some examples, the heat-conducting plate 19 can be constructed as a heat-dissipating aluminum plate.

[0202] Combination Figure 3 , Figure 5 and Figure 10 In some embodiments of this utility model, the box body 11 is provided with a positioning part 114, the box body 11 is adapted to be rotatably mounted on the outer shell 20 through the positioning part 114, and the positioning part 114 is adapted to avoid the position of the box body 11 for wiring.

[0203] For example, the positioning part 114 may include a rotating shaft 1142 and two connecting pieces 1141. One of the two connecting pieces 1141 is used to connect to the housing 11. For instance, the connecting piece 1141 connected to the housing 11 may be disposed on the housing body 111 to avoid the movable cover 112, so as to prevent the positioning part 114 from interfering with the movement of the cover 112 and causing the mounting cavity 1111 to be unable to open, thereby avoiding affecting the maintenance of the electrical control box assembly 10. At the same time, the connecting piece 1141 connected to the housing 11 is misaligned with the wiring position of the housing 11. It can also be understood that the connecting piece 1141 connected to the housing 11 is misaligned with the extension direction of the wire harness disposed on the housing 11, so as to facilitate the positioning and installation of the electrical control box assembly 10 while avoiding the positioning part 114 from interfering with the wiring on the housing 11.

[0204] The other of the two connecting pieces 1141 is used to connect to the housing 20, and the two connecting pieces 1141 can be rotatably connected by the pivot 1142, so that the box 11 can be positioned and installed on the housing 20 by the positioning part 114 and can rotate relative to the housing 20, thereby facilitating the maintenance of other components installed in the housing 20 and reducing the risk of other components being affected by the electrical control box assembly 10 blocking other components installed in the housing 20.

[0205] In some examples, the positioning part 114 is configured as a hinge, thereby enabling the box 11 to be rotatably mounted to the outer casing 20. It is understood that the configuration of the positioning part 114 as a hinge is merely an example of this application and should not be construed as a limitation of this application. The positioning part 114 can also be configured in other ways, as long as it enables the box 11 to be rotatably connected to the outer casing 20 through the positioning part 114. No specific limitation is made here.

[0206] In some other embodiments of this utility model, the positioning part 114 is used to engage with the outer shell 20.

[0207] For example, during the process of installing the electrical control box assembly 10 into the housing 20, the positioning part 114 can be engaged with the housing 20 to achieve pre-positioning of the electrical control box assembly 10, which facilitates the installation of the electrical control box assembly 10. For instance, the positioning part 114 can be provided on the box body 111 to avoid the rotatable cover 112, so as to prevent the positioning part 114 from interfering with the rotation of the cover 112 and causing the mounting cavity 1111 to be unable to be opened, thereby avoiding affecting the maintenance of the electrical control box assembly 10.

[0208] In some specific examples, the positioning part 114 can be configured as a hook, and the position on the housing 20 for installing the electrical control box assembly 10 can be provided with a snap-fit ​​protrusion or snap-fit ​​hole corresponding to the hook, so that the positioning part 114 can snap-fit ​​with the housing 20, thereby realizing the positioning and installation of the electrical control box assembly 10 onto the housing 20.

[0209] Combination Figure 3 , Figure 5 and Figure 10 In some embodiments of this utility model, the box body 11 is provided with a connecting part 113, and the fixing connector passes through the connecting part 113 and is fixed to the outer shell 20.

[0210] For example, the connecting part 113 can be configured as a connecting flange, and a through hole for the fastener to pass through can be formed on the connecting flange. Correspondingly, the outer shell 20 is provided with a hole structure opposite to the through hole. The fastener can pass through the connecting flange through the through hole and extend into the hole structure on the outer shell 20. The fastener can be configured as a screw or bolt or other threaded fastener. Correspondingly, the hole structure on the outer shell 20 can be configured as a threaded hole so that the fastener can be fixed to the outer shell 20. Thus, the box 11 can be fixed to the outer shell 20 through the connecting part 113 and the fastener, thereby realizing the fixed installation of the box 11 onto the outer shell 20 and improving the assembly reliability of the box 11.

[0211] It is understood that the above-described construction of the connecting part 113 as a connecting flange and the construction of the fixed connecting member as a threaded connecting member are merely examples of this application and should not be construed as limiting this application. The specific construction of the connecting part 113 and the fixed connecting member can be determined according to actual production requirements and is not specifically limited here.

[0212] Furthermore, combined Figure 2 and Figure 3 as well as Figure 5 The connecting part 113 is adapted to avoid the wiring position of the box 11.

[0213] For example, the connection part 113 is misaligned with the wiring position of the box body 11. This can also be understood as the connection part 113 being misaligned with the extension direction of the wire harness provided on the box body 11, so as to facilitate the positioning and installation of the electrical control box assembly 10 while avoiding interference of the connection part 113 with the wiring on the box body 11.

[0214] Furthermore, the housing 11 is adapted to rotate relative to the housing 20 via the positioning part 114 when the connecting part 113 is released from fixing to the housing 20.

[0215] For example, when it is necessary to repair a component that is located inside the housing 20 and is covered by the electrical control box assembly 10, the fixing connector can be removed from the housing 20 and the connecting part 113 to release the fixing between the connecting part 113 and the housing 20. At this time, the electrical control box assembly 10 can be rotated relative to the housing 20 through the positioning part 114 so as to expose the component covered by the electrical control box assembly 10, thereby facilitating the repair of the component covered by the electrical control box assembly 10.

[0216] Combination Figure 2 and Figure 3 In some embodiments of this utility model, the positioning part 114 and the connecting part 113 are located on opposite sides of the box body 11.

[0217] For example, in the width direction of the box body 11, the two sides of the box body 11 are respectively arranged opposite to a portion of the outer shell 20. The positioning part 114 can be arranged on one side of the box body 11 in the width direction, and the connecting part 113 can be arranged on the other side of the box body 11 in the width direction. In the process of assembling the electrical control box assembly 10 into the box body 11, the electrical control box assembly 10 can be pre-positioned on the outer shell 20 by the positioning part 114, and then further fixedly installed with the outer shell 20 by the connecting part 113 and the fixing connector. By arranging the positioning part 114 and the connecting part 113 on opposite sides of the box body 11, it is beneficial to improve the operational convenience when assembling the electrical control box assembly 10, thereby improving the assembly efficiency of the air conditioning equipment 100.

[0218] In some other embodiments of this utility model, connecting portions 113 can be provided on both opposite sides of the box body 11, and positioning portions 114 can be provided on the side of the connecting portions 113 away from the shell. When the electrical control box assembly 10 is pre-positioned with the shell 20, the box body 11 can be engaged with the shell 20 through the positioning portions 114 provided on both sides, so as to improve the engagement stability of the box body 11 and the shell 20 and reduce the risk of the box body 11 tilting. Then, the connecting portions 113 provided on both sides of the box body 11 are connected to the shell 20 respectively, so as to further improve the connection reliability of the box body 11 and the shell 20 and reduce the risk of the box body 11 shaking relative to the shell 20.

[0219] Reference Figure 1 According to an embodiment of the present utility model, the air conditioning device 100 includes: a housing 20 and an electrical control box assembly 10 as described above. The housing 20 has an inspection port 204, and the electrical control box assembly 10 is disposed inside the housing 20.

[0220] For example, the electrical control box assembly 10 is disposed within the housing 20, which can protect the electrical control box assembly 10 and reduce the risk of damage to the electrical control box assembly 10. Considering that the components disposed within the housing 20 (including but not limited to the electrical control box assembly 10) may malfunction during the use of the air conditioning equipment 100, the housing 20 is provided with an inspection port 204 to facilitate maintenance personnel to inspect the components disposed within the housing 20.

[0221] Further reference Figure 1 The control box assembly 10 is positioned opposite the inspection port 204 to facilitate the maintenance of the control box assembly 10. The main control module 121 is positioned closer to the inspection port 204 than the other power modules 12 to facilitate the maintenance of the main control module 121 and to facilitate the heat dissipation of the main control module 121.

[0222] In related technologies, the unreasonable arrangement of components in the electrical control box assembly makes it difficult to maintain the main control module and affects the maintenance efficiency of the electrical control box assembly.

[0223] The air conditioning device 100 of this application embodiment facilitates the maintenance of the electrical control box assembly 10 by setting the electrical control box assembly 10 opposite to the access port 204. Furthermore, by setting the main control module 121 closer to the access port 204 relative to the other power modules 12, the maintenance convenience of the main control module 121 is improved, thereby improving the maintenance efficiency of the electrical control box assembly 10 and facilitating the heat dissipation of the main control module 121.

[0224] According to the embodiment of the present utility model, the air conditioning equipment 100 is equipped with the aforementioned electrical control box assembly 10. Most of the power modules 12 in the electrical control box assembly 10 are housed in the mounting cavity 1111 and protected by the box body 11, reducing the impact of external environmental substances on most of the power modules 12 and lowering the risk of damage to most of the power modules 12. The main control module 121 and the terminal block 17 are both located outside the mounting cavity 1111, facilitating the assembly of the main control module 121 and the terminal block 17, and facilitating the electrical connection between the main control module 121 and the terminal block 17 and the power modules 12 in the mounting cavity 1111. This improves the production efficiency of the electrical control box assembly 10 and also facilitates the wiring and maintenance of the main control module 121 and the terminal block 17, thus improving the installation and maintenance efficiency of the electrical control box assembly 10 when applied to air conditioning. The electrical control box assembly 10 is positioned opposite the inspection port 204, further enhancing the convenience of maintaining the electrical control box assembly 10.

[0225] like Figure 1 As shown, in some embodiments of the present invention, a first chamber 201 and a second chamber 202 are formed inside the outer casing 20. The first chamber 201 and the second chamber 202 are spaced apart. The first chamber 201 is used to install an outdoor heat exchanger and a fan, and the second chamber 202 is used to install a compressor 30 and an electrical control box assembly 10.

[0226] For example, the first chamber 201 and the second chamber 202 can be arranged at intervals in the width direction of the electrical control box assembly 10. An outdoor heat exchanger and a fan are provided in the first chamber 201. The fan can rotate in the first chamber 201 and form a negative pressure to draw outdoor air into the first chamber 201 to exchange heat with the outdoor heat exchanger. The airflow after heat exchange can be discharged from the casing under the drive of the fan. The compressor 30 and the electrical control box assembly 10 are arranged in the second chamber 202 so that the compressor 30 and the outdoor heat exchanger can be arranged at intervals to reduce the thermal interference of the outdoor heat exchanger on the compressor 30 and the electrical control box assembly 10.

[0227] Furthermore, the electrical control box assembly 10 is located above the compressor 30 to facilitate the arrangement of the electrical control box assembly 10 and the compressor 30, prevent them from interfering with each other during assembly, and at the same time facilitate the rational division of the space in the second chamber 202, improve the space utilization rate of the second chamber 202, thereby helping to reduce the size of the air conditioning equipment 100.

[0228] Reference Figure 1 In some embodiments of the present invention, the outer shell 20 includes a shell body 21 and a connecting plate (not shown). The shell body 21 forms a first chamber 201 and a second chamber 202 open on one side. The open end of the second chamber 202 is formed as an inspection port 204. The connecting plate is detachably connected to the shell body 21 to selectively block the inspection port 204.

[0229] An air outlet 203 is formed on the side wall of the shell body 21 opposite to the first chamber 201. A fan can drive the airflow entering the shell 20 to be discharged through the air outlet 203. The air outlet 203 can be located on the top wall of the shell body 21 opposite to the first chamber, or it can be located on the side wall of the shell body 21 opposite to the first chamber 201. It is understood that the specific location of the air outlet 203 can be determined according to actual production requirements, and is not specifically limited here.
