Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an electronic control component and an air conditioning device. Background Technology

[0002] In air conditioning systems, the overall performance of the electronic control components directly affects the system's overall performance. Therefore, to improve the performance of an air conditioning system, it is necessary to improve the overall performance of the electronic control components. Summary of the Invention

[0003] This application provides an electronic control component and an air conditioning device, which can improve the overall performance of the electronic control component.

[0004] In a first aspect, this application provides an electronic control component, including a grounding shell, a frame, an electronic control integration unit, a first connector, and a second connector. The frame includes multiple constituent walls that form an installation space. At least one constituent wall includes a metal plate, which has a first grounding portion and a second grounding portion. The electronic control integration unit is installed within the installation space and includes a main circuit board. The first connector connects the metal plate to the main circuit board and electrically connects the first grounding portion to the main circuit board. The second connector connects the metal plate to the grounding shell and electrically connects the second grounding portion to the grounding shell.

[0005] The electronic control component of this application embodiment includes a metal plate as one of the constituent walls of the frame. A first grounding portion and a second grounding portion are provided on the metal plate. A first connector enables mechanical and electrical connections between the main circuit board of the electronic control integration unit and the metal plate of the frame, and a second connector enables mechanical and electrical connections between the metal plate of the frame and the grounding shell. This allows the main circuit board to be stably mounted on the frame, and the frame to be stably mounted on the grounding shell, while simultaneously achieving a grounding connection between the electronic control integration unit and the grounding shell. In other words, the first and second grounding portions achieve stable assembly and grounding connection of the electronic control component with a simple structure. This not only improves the assembly stability and electrical safety of the electronic control component but also simplifies its installation structure and enhances the convenience of maintenance, thus improving the overall performance of the electronic control component.

[0006] In some embodiments, at least a portion of the metal plate is reused as a heat exchange wall, through which the main circuit board and the grounding shell exchange heat. The metal plate serves as both a grounding medium and a heat dissipation medium, simplifying the overall structure of the electronic control components, improving safety performance, and enhancing heat dissipation performance.

[0007] In some embodiments, a gap is formed between the heat exchange wall and the main circuit board; the electronic control assembly also includes a filling portion that fills the gap between the heat exchange wall and the main circuit board, and the filling portion exchanges heat with the grounding shell through the heat exchange wall. Therefore, the heat exchange efficiency is improved by providing the filling portion.

[0008] In some embodiments, the main circuit board and the heat exchange wall are spaced apart, and the filling portion is located on opposite sides of the main circuit board along the spacing direction between them. This further improves heat dissipation efficiency.

[0009] In some embodiments, the first connector penetrates the main circuit board, and one end of the first connector is located on the side of the main circuit board away from the heat exchange wall; the filling portion submerges the end of the first connector located on the side of the main circuit board away from the heat exchange wall. Thus, the first connector penetrates the main circuit board to connect the structures on both sides, and the filling portion can fill the void formed by the penetration.

[0010] In some embodiments, a support platform protrudes from the inner side of the frame. This support platform is configured to support the main circuit board and create a gap between the main circuit board and the heat exchange wall. Based on this, by adjusting the size and position of the support platform, the distance between the main circuit board and the heat exchange wall along a third direction can be adjusted, thereby allowing for adjustment of the thickness of the third thermally conductive material between the second circuit and the heat exchange wall.

[0011] In some embodiments, the plurality of constituent walls include peripheral walls that surround the heat exchange wall to form the mounting space; the peripheral walls are integrally formed with the heat exchange wall. Based on this, the frame structure is more stable.

[0012] In some embodiments, the peripheral wall and the heat exchange wall are integrally formed from the same thermally conductive material. This makes the frame construction more convenient.

[0013] In some embodiments, the peripheral wall and the heat exchange wall are integrally formed from two different thermally conductive materials. Based on this, the appropriate materials for different parts can be selected during the design process according to different needs.

[0014] In some embodiments, the peripheral wall is made of an insulating, non-thermal-conducting material, while the heat exchange wall is any one of a thermally conductive metal, thermally conductive ceramic, or thermally conductive plastic. Therefore, the heat exchange wall has good thermal conductivity, and the peripheral wall cost is low.

[0015] In some embodiments, the metal plate includes a heat exchange wall located on the inner side of the peripheral wall and an extension wall located on the outer side of the peripheral wall; the second grounding portion is disposed on the extension wall. Based on this, the operator can assemble and disassemble the second grounding portion from the outside of the frame, making the assembly and disassembly between the frame and the grounding shell more convenient.

[0016] In some embodiments, the first grounding portion includes a first bolt post protruding from the metal plate on the side facing the main circuit board, the first bolt post having a first bolt hole; the first connector includes a first grounding bolt adapted to the first bolt hole. Thus, a stable mechanical and electrical connection between the metal plate and the main circuit board is achieved through the cooperation of the first grounding bolt and the first bolt hole.

[0017] In some embodiments, one end of the first bolt post is connected to the metal plate, and the other end abuts against the main circuit board. Thus, the first bolt post also provides support for the main circuit board.

[0018] In some embodiments, the metal plate has an insulating layer on the side facing the main circuit board. The insulating layer increases the creepage distance between the main circuit board and its connected electronic components and the metal plate, thus improving safety.

[0019] In some embodiments, the frame is provided with an installation port communicating with the installation space; the electronic control component also includes a cover that can be closed with the frame to cover the installation port. Therefore, after the components in the installation space are installed, the cover can be closed with the frame to provide protection against corrosion and debris.

[0020] In some embodiments, the electronic control integration unit further includes a housing comprising multiple component walls, at least one of which is configured as a heat-conducting wall. The frame has a first clearance groove, and the cover has a second clearance groove. When the cover is closed with the frame, the first and second clearance grooves form a clearance opening, exposing at least a portion of the heat-conducting wall for external heat exchange fluid to flow through. Thus, when the cover is closed with the frame, it protects the components within the installation space, while allowing the fins to exchange heat with the external environment.

[0021] In some embodiments, the heat-conducting wall has a plurality of spaced-apart fins, with a first gap between adjacent fins; the frame has at least one second ventilation slot, which corresponds to at least one of the first gaps; the cover fits over the frame along the spaced-apart fins, and the cover has at least one third ventilation slot, which corresponds to at least one other first gap. Thus, while utilizing the frame and cover for protection, more airflow can be directed to the fins through the second ventilation slots of the frame and the third ventilation slots of the cover to improve heat exchange efficiency.

[0022] In some embodiments, the main circuit board has a plurality of first terminals and a plurality of second terminals; the cover has a foolproof part, a first clearance part, and a second clearance part; when the cover is closed with the frame, along the arrangement direction of the first and second terminals, the first clearance part and the second clearance part are respectively located on opposite sides of the foolproof part, the first clearance part exposes the first terminal, and the second clearance part exposes the second terminal. Thus, during installation, the closing direction of the cover can be quickly determined based on the foolproof part, thereby improving installation efficiency.

[0023] In some embodiments, one of the cover and the frame has a guide protrusion, and the other has a guide groove extending along the closing direction of the cover and the frame. The guide groove is configured to guide the guide protrusion to move along the closing direction of the cover and the frame. And / or, one of the cover and the frame has a locking groove, and the other has a hook. The hook engages with the locking groove, and the hook can elastically deform and disengage from the locking groove under external force. Thus, the closing of the cover and the frame is smoother and more stable.

[0024] Secondly, this application provides an air conditioning device, including an electrical control support and the aforementioned electrical control component, wherein the electrical control component is mounted on the electrical control support. Based on this, the electrical control component of the air conditioning device has good heat dissipation performance.

Thus, a stable assembly between the electronic control component and the partition plate is achieved with a simple structure, and the partition plate is used to achieve the grounding connection of the electronic control component. This not only improves the assembly stability and electrical safety of the electronic control component, but also simplifies the installation structure of the electronic control component and improves the convenience of inspection and maintenance, thereby enhancing the overall performance of the electronic control component.

[0026] In some embodiments, the partition plate is reused as the electrical control support member. Thus, the partition plate simultaneously performs multiple functions, simplifying the structure.

Detailed Implementation

[0058] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0059] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0060] Considering the safety of the electronic control module that controls the fan drive during transportation, use, and maintenance, the exemplary embodiment places the electronic components in the hollow space inside the housing to avoid exposing the electronic components to the outside, thereby reducing the risk of damage from drops and collisions during transportation, the risk of corrosion from the usage environment, and the risk of electric shock to maintenance personnel due to accidental contact.

[0061] To improve the protection of the internal electronic components by the housing, the sealing effect of the housing needs to be improved. However, improving the sealing effect of the housing will cause the internal electronic components to overheat, thereby reducing the stability and safety of the electronic control module.

[0062] To address the aforementioned issues, this application provides an electronic control module that uses a housing to protect internal electronic components. At least one component wall of the housing is configured as a heat-conducting wall, and a first heat-conducting material of the heat-conducting wall exchanges heat with at least one external cold source. A second heat-conducting layer material is filled inside the housing, and the second heat-conducting material buries at least a portion of the first electronic components. This allows the heat from the first electronic components to be rapidly exchanged with one or more external cold sources through the second and first heat-conducting materials, thereby improving the heat dissipation performance of the electronic control module.

[0063] See Figures 1-3 In some embodiments, the electronic control module 32 includes a housing 1, a second thermally conductive material 2a, and electronic components 3.

[0064] The shell 1 includes multiple component walls 1a, which form a hollow space 1b. The component walls 1a can be planar, curved, or a combination thereof. When a component wall 1a is planar, it can be constructed as a circle, ellipse, triangle, quadrilateral, pentagon, hexagon, or a combination thereof. The hollow space 1b defined by the multiple component walls 1a can be, for example, cylindrical, triangular prism, quadrangular prism, pentagonal prism, hexagonal prism, or a combination thereof.

[0065] At least one component wall 1a is configured as a heat-conducting wall 1a1, that is, one or more component walls 1a are configured as heat-conducting walls 1a1. The configuration of multiple component walls 1a as heat-conducting walls 1a1 includes a portion of the multiple component walls 1a being configured as heat-conducting walls 1a1, and all of the multiple component walls 1a being configured as heat-conducting walls 1a1.

[0066] The thermally conductive wall 1a1 includes a first thermally conductive material 1a11, which may include at least one of a thermally conductive metal, a thermally conductive ceramic, or a thermally conductive plastic. The thermally conductive metal may include at least one of silver, gold, copper, or aluminum. The thermally conductive ceramic may include at least one of oxides, nitrides, carbides, or borides. The thermally conductive plastic may include a general-purpose plastic or engineering plastic with at least one thermally conductive filler such as a metal oxide, nitride, or carbon.

[0067] The first thermally conductive material 1a11 exchanges heat with at least one external cold source, that is, the first thermally conductive material 1a11 exchanges heat with one or more external cold sources. Specifically, this includes one external cold source exchanging heat with one portion of the first thermally conductive material 1a11 constituting wall 1a, one external cold source exchanging heat with multiple portions of the first thermally conductive material 1a11 constituting wall 1a, and multiple external cold sources exchanging heat with one portion of the first thermally conductive material 1a11 constituting wall 1a. Optionally, the direction of heat exchange between the first thermally conductive material 1a11 and the external cold source includes direct contact and indirect contact.

[0068] Continue reading Figures 1-3 The second thermally conductive material 2a is filled within the hollow space 1b, and the second thermally conductive material 2a is in thermally conductive contact with the first thermally conductive material 1a11. The second thermally conductive material 2a may include, for example, a thermally conductive filler material, thus enabling it to more fully fill spaces of various shapes and sizes, thereby improving thermal conductivity. Optionally, the thermally conductive filler material includes at least one of thermally conductive paste, thermally conductive phase change material, thermally conductive adhesive, and thermally conductive gel.

[0069] Electronic component 3 is installed within the hollow space 1b. For example, electronic component 3 is directly installed on the component wall 1a, or indirectly installed on the component wall 1a through other mounting structures connected to the component wall 1a. In this way, the housing 1 can protect the electronic component 3. Electronic component 3 includes a first circuit board 3a and a plurality of first electronic components 3b mounted on the first circuit board 3a. At least some of the first electronic components 3b are embedded in a second thermally conductive material 2a, i.e., one or more first electronic components 3b are embedded in the second thermally conductive material 2a. The first circuit board 3a is, for example, a fan drive circuit board, which has a drive chip 3b1 configured to drive the fan of an air conditioning unit. The first electronic components 3b embedded in the second thermally conductive material 2a may be partially or completely embedded within the second thermally conductive material 2a.

[0070] Based on this, the heat of the first electronic component 3b embedded in the second thermally conductive material 2a can be quickly transferred to the first thermally conductive material 1a11 through the second thermally conductive material 2a, and then quickly transferred to the outside of the housing 1 through one or more thermal conduction paths of the first thermally conductive material 1a11, thereby improving the heat dissipation performance of the electronic control module 32 and thus improving the stability and safety of the electronic control module 32.

[0071] Continue reading Figures 1-3In some embodiments, at least one external cold source includes a first external cold source 4, which includes an airflow located outside the heat-conducting wall 1a1. The outer surface of the heat-conducting wall 1a1 is provided with a plurality of spaced-apart fins 1a2, which exchange heat with the airflow. The plurality of fins 1a2 are arranged either uniformly or non-uniformly. Based on this, the plurality of fins 1a2 have a large heat exchange area, thereby exchanging heat with the first external cold source 4 more efficiently.

[0072] For example, the first external cold source 4 is the airflow in the air conditioning circulation system. In this way, the cooling capacity of the air conditioning circulation system can be used to cool the electronic control module 32, thereby improving the heat dissipation efficiency of the electronic control module 32. In other embodiments, for other design purposes, the first external cold source 4 may also be the airflow outside the air conditioning circulation system.

[0073] Optionally, the surface of the fin 1a2 is provided with alternating concave and convex portions to increase the surface area of ​​the fin 1a2, thereby increasing the heat exchange area between the fin 1a2 and the airflow flowing through the fin 1a2.

[0074] Continue reading Figures 1-3 In some embodiments, the housing 1 includes a first housing 1c and a second housing 1d, wherein the material of the first housing 1c is the same as or different from that of the second housing 1d. In an exemplary embodiment, the materials of the first housing 1c and the second housing 1d are different; the first housing 1c is made of plastic, and the second housing 1d is made of aluminum. The first housing 1c is hollow, and an opening 1c3 is provided on one side of the first housing 1c. At least a portion of the second housing 1d is embedded in the opening 1c3 and forms a hollow space 1b with the first housing 1c. In this way, the connection between the first housing 1c and the second housing 1d is more stable, less prone to damage, and more conducive to forming a sealed space.

[0075] Combined Figure 4 Furthermore, the heat-conducting wall 1a1 is located in the second shell 1d, and the fins 1a2 are located on the outside of the second shell 1d. The portion of the first shell 1c nested with the second shell 1d is provided with a first ventilation slot 1c41, and the gap between the first ventilation slot 1c41 and the gap between two adjacent fins 1a2 are correspondingly set. In this way, a stable connection between the first shell 1c and the second shell 1d is ensured, and more airflow can be directed to the fins 1a2 through the first ventilation slot 1c41 to improve heat exchange efficiency.

[0076] Optionally, the number of first ventilation slots 1c41 can be one or more. When there is only one first ventilation slot 1c41, one first ventilation slot 1c41 can be correspondingly arranged with one or more gaps, that is, one first ventilation slot 1c41 can supply air to one or more gaps to improve heat exchange efficiency and ensure that the first shell 1c has high structural strength. When there are multiple first ventilation slots 1c41, each first ventilation slot 1c41 can be correspondingly arranged with one or more gaps. For example, there are multiple first ventilation slots 1c41, and the multiple first ventilation slots 1c41 are arranged one-to-one with the gaps of multiple fins 1a2, so that air can be supplied to the fins 1a2 more evenly.

[0077] See Figure 5 In some embodiments, at least one external cold source includes a first external cold source 4, which includes a refrigeration pipe 4a1 and a first refrigerant 4a2, with the first refrigerant 4a2 circulating through the refrigeration pipe 4a1. The heat-conducting wall 1a1 is in thermal contact with the refrigeration pipe 4a1. Based on this, the first refrigerant 4a2 cools the heat-conducting wall 1a1 through the refrigeration pipe 4a1, thereby achieving efficient heat dissipation for the electronic control module 32.

[0078] Combined Figure 6 For example, the first refrigerant 4a2 is a refrigerant from within the air conditioning circulation system 10000. Specifically, the air conditioning circulation system 10000 includes an indoor unit 1000b, an outdoor unit 1000a, and an air conditioning pipe connecting the indoor unit 1000b and the outdoor unit 1000a. The air conditioning pipe includes, for example, a liquid pipe 2000, within which refrigerant circulates. Depending on design requirements, the liquid pipe 2000 may be configured with a main pipe and branch pipes. The first refrigerant 4a2 may specifically be a refrigerant from the main pipe or a refrigerant from a branch pipe. In this way, the refrigerant within the air conditioning circulation system 10000 can be fully utilized, and the heat dissipation performance of the electronic control module 32 can be improved. In other embodiments, for other design purposes, the first refrigerant 4a2 may also be a refrigerant from outside the air conditioning circulation system 10000.

[0079] Continue reading Figure 5 In some embodiments, the surface of the heat-conducting wall 1a1 is recessed with a mounting groove 1a4, and the refrigeration pipe 4a1 is disposed within the mounting groove 1a4, with at least a portion of the outer surface of the refrigeration pipe 4a1 in contact with the groove wall of the mounting groove 1a4. The number of refrigeration pipes 4a1 may be one or more. This results in a large contact area between the refrigeration pipe 4a1 and the heat-conducting wall 1a1, thereby achieving higher heat exchange efficiency. Furthermore, the recessed mounting groove 1a4 reduces the space occupied by the refrigeration pipe 4a1.

[0080] For example, the refrigeration pipe 4a1 is a circular pipe, and on a cross-section perpendicular to the axial direction of the circular pipe, 1 / 2, 2 / 3, or 3 / 4 of the outer surface of the refrigeration pipe 4a1 is in contact with the wall of the mounting groove 1a4. This results in a larger contact area between the refrigeration pipe 4a1 and the wall of the mounting groove 1a4, leading to higher heat exchange efficiency and a more stable connection between the refrigeration pipe 4a1 and the mounting groove 1a4. In other embodiments, for other design purposes, the cross-sectional shape of the refrigeration pipe 4a1 can be elliptical, triangular, quadrilateral, pentagonal, hexagonal, or a combination thereof.

[0081] Optionally, the refrigeration pipe 4a1 is snapped into the mounting groove 1a4, for example, by an interference fit, so that the refrigeration pipe 4a1 and the mounting groove 1a4 can make more full contact.

[0082] Optionally, the refrigeration pipe 4a1 is bonded and fixed to the mounting groove 1a4, for example, by bonding and fixing it after curing with thermally conductive adhesive, so as to ensure sufficient heat exchange between the refrigeration pipe 4a1 and the groove wall of the mounting groove 1a4.

[0083] Continue reading Figure 5 In some embodiments, the mounting groove 1a4 is provided on the outer surface of the heat-conducting wall 1a1, that is, the mounting groove 1a4 is provided on the side surface of the heat-conducting wall 1a1 facing away from the hollow space 1b. In this way, interference between the refrigeration pipe 4a1 and the components in the hollow space 1b can be avoided.

[0084] See Figure 7 In some embodiments, at least one external cold source includes a first external cold source 4. The heat-conducting wall 1a1 has a refrigerant channel 4b1 inside. Based on the corresponding design purpose, the cross-sectional shape of the refrigerant channel 4a1 can be circular, elliptical, triangular, quadrilateral, pentagonal, hexagonal, or a combination thereof. The first external cold source 4 includes a second refrigerant 4b2 circulating through the refrigerant channel 4b1. The source of the second refrigerant 4b2 can refer to the source of the first refrigerant 4a2. It should be noted that the source of the second refrigerant 4b2 can be the same as or different from the source of the first refrigerant 4a2. The number of refrigerant channels 4b1 can be one or more. Thus, the second refrigerant 4b2 within the refrigerant channel 4b1 can more fully exchange heat with the heat-conducting wall 1a1, thereby improving heat exchange efficiency. Furthermore, the refrigerant channel 4b1 is located inside the heat-conducting wall 1a1, requiring no additional space and avoiding interference with components within the hollow space 1b.

[0085] Combination Figure 1 and Figure 8In some embodiments, at least one external cold source includes a second external cold source 5, which includes a mounting plate 51, and the housing 1 is mounted on the mounting plate 51. The mounting plate 51 is exposed to the air, for example, exposed to the air outside the air conditioning unit; or, the mounting plate 51 is located in the airflow circulation path, for example, located in the airflow circulation path of the air conditioning circulation system; or, the mounting plate 51 is exposed to the air and located in the airflow circulation path. Based on this, heat can be quickly transferred between the housing 1 and the mounting plate 51, while the mounting plate 51 can also exchange heat with the external air or the circulating airflow, thereby improving the heat dissipation performance of the electronic control module 32.

[0086] Optionally, the mounting plate 51 may be made of metal, which has high thermal conductivity, thereby improving heat dissipation efficiency.

[0087] See Figure 3 In some embodiments, the housing 1 includes a first housing 1c and a second housing 1d. The first housing 1c has a first mounting surface 1c22 on one side along the first direction D1. At least a portion of the end face of the second housing 1d along the first direction D1 is fitted with the first mounting surface 1c22, forming a hollow space 1b between the first housing 1c and the second housing 1d. The first mounting surface 1c22 is, for example, a plane, a curved surface, or a combination thereof. In this way, the first housing 1c and the second housing 1d can each flexibly select materials and shapes according to requirements and assemble to form the housing 1.

[0088] Optionally, the first shell 1c and the second shell 1d are secured together by fasteners to make the assembly between the first shell 1c and the second shell 1d more stable. Fasteners include, for example, screws or bolts, which are simple in structure and easy to assemble and disassemble.

[0089] Combination Figure 1 , Figure 2 and Figure 4 In some embodiments, the housing 1 is provided with an overflow space 1b1 communicating with the hollow space 1b. The overflow space 1b1 can accommodate the second thermally conductive material 2a overflowing from the hollow space 1b. Based on this, during the process of filling the hollow space 1b with the second thermally conductive material 2a, the overflowing second thermally conductive material 2a can be stored in the overflow space 1b1, thereby reducing the risk that the second thermally conductive material 2a will overflow to other parts and affect the normal operation of other components or reduce the appearance of the surface.

[0090] In some embodiments, the overflow space 1b1 is located on one side of the hollow space 1b along the second direction D2. The first direction D1 intersects the second direction D2, for example, the first direction D1 is perpendicular to the second direction D2 or the angle between them is acute.

[0091] It is understandable that when the first shell 1c and the second shell 1d are installed and fitted along the first direction D1, due to dimensional tolerances in actual production, the first mounting surface 1c22 and the corresponding end face of the second shell 1d cannot be completely fitted, and a gap exists between them along the first direction D1. Based on this, during the process of filling the hollow space 1b with the second thermally conductive material 2a, the second thermally conductive material 2a may overflow to the outside of the hollow space 1b through this gap. Since the sidewall of this gap blocks the overflow path of the second thermally conductive material 2a along the first direction D1, the overflow direction of the second thermally conductive material 2a intersects with the first direction D1. In this embodiment, the overflow space 1b1 is located on one side of the hollow space 1b along the second direction D2, which intersects with the first direction D1, so that the overflow space 1b1 can more timely and efficiently contain the overflowing second thermally conductive material 2a.

[0092] In addition, when the second thermally conductive material 2a is cured in the gap, it can also act as an adhesive between the first shell 1c and the second shell 1d, making the assembly between the first shell 1c and the second shell 1d more stable and the sealing effect better.

[0093] Combination Figure 1 , Figure 2 and Figure 4 In some embodiments, the housing 1 is further provided with a discharge hole 1b2 communicating with the overflow space 1b1. The discharge hole 1b2 can discharge the second thermally conductive material 2a in the overflow space 1b1 to the outside of the housing 1. Based on this, during the process of filling the hollow space 1b with the second thermally conductive material 2a, the discharge hole 1b2 can discharge part of the second thermally conductive material 2a, avoiding excessive local pressure in the hollow space 1b that could cause the housing 1 to crack. In this way, the second thermally conductive material 2a can be filled more fully until the area in the hollow space 1b where no components are installed is filled with the second thermally conductive material 2a.

[0094] Continue reading Figure 1 , Figure 2 and Figure 4 In some embodiments, the housing 1 is further provided with a filling port 1b3 communicating with the hollow space 1b, and the filling port 1b3 and the discharge hole 1b2 are located at opposite ends of the housing 1. In this way, in the initial stage of filling, the second thermally conductive material 2a is farther away from the discharge hole 1b2, and will preferentially fill the hollow space 1b rather than be discharged from the discharge hole 1b2, thereby making the filling more complete.

[0095] In some embodiments, a barrier wall 1b4 is provided between the hollow space 1b and the overflow space 1b1. The barrier wall 1b4 has a glue outlet 1b5, and the hollow space 1b and the overflow space 1b1 are connected through the glue outlet 1b5. In this way, excess glue in the hollow space 1b can enter the overflow space 1b1 through the glue outlet 1b5. The glue outlet 1b5 and the discharge hole 1b2 are spaced apart along a third direction D3. The first direction D1 intersects the third direction D3, for example, the first direction D1 is perpendicular to the third direction D3 or the angle between the first direction D1 and the third direction D3 is acute. Thus, after the glue in the hollow space 1b enters the overflow space 1b1 through the glue outlet 1b5, it needs to flow a certain distance along the third direction D3 to reach the discharge hole 1b2, which slows down the glue discharge speed, thereby reducing the risk of a large amount of glue being discharged when the hollow space 1b is not full, and thus reducing waste.

[0096] Continue reading Figures 1-4 In some embodiments, the first shell 1c has two limiting walls 1c4 opposite each other along the second direction D2, and the second shell 1d is located between the two limiting walls 1c4. In this way, the two limiting walls 1c4 can limit the second shell 1d, preventing the second shell 1d from shifting along the second direction D2, thereby improving the stability of the shell 1.

[0097] Furthermore, the first shell 1c also has a first ventilation slot 1c41 that penetrates the limiting wall 1c4 along the second direction D2. A heat-conducting wall 1a1 is located in the second shell 1d. On the side of the heat-conducting wall 1a1 opposite to the first mounting surface 1c22, multiple spaced fins 1a2 are provided. The fins 1a2 extend along the first direction D1, and a first gap G1 extending along the first direction D1 is provided between two adjacent fins 1a2. The two sides of the first gap G1 are respectively connected to the corresponding first ventilation slots 1c41. The number of first ventilation slots 1c41 is one or more. In this way, the airflow outside the shell 1 can flow more smoothly through the first ventilation slots 1c41 to the fins 1a2. Furthermore, since the overflow space 1b1 can accommodate the second heat-conducting material 2a overflowing from the hollow space 1b, the risk of the first ventilation slots 1c41 and the fins 1a2 being blocked by the second heat-conducting material 2a is reduced.

[0098] Optionally, the cross-sectional area of ​​the first ventilation slot 1c41 perpendicular to the second direction D2 is less than or equal to the cross-sectional area of ​​the first gap G1 perpendicular to the second direction D2. In this way, the limiting wall 1c4 can prevent some debris from entering the first gap G1 through the first ventilation slot 1c41, ensuring that the fins 1a2 have a good heat exchange effect.

[0099] Continue reading Figures 1-4In some embodiments, the first shell 1c is provided with a plurality of spaced-apart first ventilation slots 1c41, each first ventilation slot 1c41 corresponding to a different first gap G1. In this way, the plurality of first ventilation slots 1c41 deliver air into the first gap G1 more evenly, thereby improving the heat dissipation effect.

[0100] In some embodiments, the hollow space 1b is located on one side of the overflow space 1b1 along the second direction D2, and the first ventilation slot 1c41 is located on the other side of the overflow space 1b1 along the second direction D2. In other words, if the second thermally conductive material 2a overflowing from the hollow space 1b is to enter the first ventilation slot 1c41, it needs to pass through the overflow space 1b1 first, reducing the risk of the first ventilation slot 1c41 being blocked by the overflowing second thermally conductive material 2a.

[0101] In some embodiments, the housing 1 is provided with an overflow space 1b1 communicating with the hollow space 1b and a discharge hole 1b2 communicating with the overflow space 1b1. The overflow space 1b1 has an overflow wall surface 1b6 facing the second housing 1d along a first direction D1. The distance between the overflow wall surface 1b6 and the discharge hole 1b2 along the first direction D1 is smaller than the distance between the overflow wall surface 1b6 and the first ventilation groove 1c41 along the first direction D1. In this way, the adhesive in the overflow space 1b1 will preferentially be discharged through the discharge hole 1b2 and will not easily be discharged through the first ventilation groove 1c41, thereby reducing the risk of the first ventilation groove 1c41 being blocked.

[0102] Continue reading Figures 1-4 In some embodiments, the first shell 1c includes a first component wall 1c1 and a second component wall 1c2, wherein the first component wall 1c1 and the second component wall 1c2 are integral or separate structures. The second shell 1d includes a third component wall 1d1, which is configured as a heat-conducting wall 1a1. The first component wall 1c1, the second component wall 1c2, and the third component wall 1d1 form a hollow space 1b. The first component wall 1c1 and the third component wall 1d1 are located on both sides of the hollow space 1b along a first direction D1. The second component wall 1c2 extends from the first component wall 1c1 along the first direction D1 toward the third component wall 1d1, and the second component wall 1c2 surrounds the periphery of the hollow space 1b.

[0103] For example, the first component wall 1c1 and the second component wall 1c2 are an integral structure. The second component wall 1c2 surrounds and connects to the first component wall 1c1 to form a hollow first shell 1c with an opening 1c3 at one end. The third component wall 1d1 is installed at the opening 1c3 end of the first shell 1c to form a shell 1 with a hollow space 1b. To facilitate potting and other possible needs, an opening structure may also be provided on the first shell 1c or the second shell 1d. When the opening structure is provided on the second component wall 1c2 of the first shell 1c, depending on the size of the opening structure, the second component wall 1c2 may be arranged to surround and connect to the first component wall 1c1 or partially surround the first component wall 1c1.

[0104] Furthermore, the inner side of the second component wall 1c2 is provided with a mounting protrusion 1c21. The mounting protrusion 1c21 forms a first mounting surface 1c22 on its surface facing away from the first component wall 1c1 along the first direction D1. The mounting protrusion 1c21 also has a second mounting surface 1c23 facing away from the second component wall 1c2 along a third direction D3. The first direction D1, the second direction D2, and the third direction D3 intersect each other in pairs; for example, they are perpendicular to each other or form an acute angle. The third component wall 1d1 is provided with a mounting recess 1d11, which has a first wall surface 1d12 and a second wall surface 1d13 connected to each other. The first wall surface 1d12 is fitted with the first mounting surface 1c22, and the second wall surface 1d13 is fitted with the second mounting surface 1c23. Based on this, by constructing the assembly surface between the third component wall 1d1 and the second component wall 1c2 as a corner structure combining multiple surfaces, the assembly area between the third component wall 1d1 and the second component wall 1c2 is increased, making the assembly more stable. Furthermore, the overflow path of the second thermally conductive material 2a within the gap between the third component wall 1d1 and the second component wall 1c2 is extended, reducing the risk of the second thermally conductive material 2a overflowing outside the housing 1.

[0105] See Figure 1 In some embodiments, the inner surface of the heat-conducting wall 1a1 is provided with a protrusion 1a3, which contacts at least one first electronic component 3b. Based on this, the first electronic component 3b in contact with the protrusion 1a3 can directly exchange heat with the heat-conducting wall 1a1. Furthermore, when the first electronic component 3b is also in contact with the second heat-conducting material 2a, it can also exchange heat with the heat-conducting wall 1a1 through the second heat-conducting material 2a, thereby improving heat dissipation efficiency.

[0106] Optionally, the electronic component 3 includes a driver chip 3b1, which contacts the protrusion 1a3. Thus, the driver chip 3b1, which generates more heat, can directly exchange heat with the heat-conducting wall 1a1, and can also exchange heat with the heat-conducting wall 1a1 through the second heat-conducting material 2a, thereby improving heat dissipation performance.

[0107] Combination Figure 1 and Figure 8 Optionally, the housing 1 includes a first housing 1c and a second housing 1d. The heat-conducting wall 1a1 is located in the second housing 1d. The second housing 1d has a fixing hole 1f at the position corresponding to the protrusion 1a3. The first housing 1c and the second housing 1d are fixed together by fasteners passing through the fixing hole 1f. The fixing hole 1f is, for example, a threaded hole, and the fastener is, for example, a screw or bolt. Based on this, since the protrusion 1a3 protrudes from the inner surface of the heat-conducting wall 1a1, the thickness of this part is increased, the structural strength of this part is improved, thereby reducing the risk of damage to the heat-conducting wall 1a1 during the tightening of screws or bolts.

[0108] See Figure 1 In some embodiments, the first circuit board 3a has a first side S1 and a second side S2 opposite to each other along a first direction D1, and both the first side S1 and the second side S2 are provided with first electronic components 3b. The first electronic components 3b located on the first side S1 and the second side S2 are both embedded in a second thermally conductive material 2a, and the second thermally conductive materials 2a on the first side S1 and the second side S2 are thermally connected. The second thermally conductive material on the first side S1 is in thermal contact with the thermally conductive wall 1a1. Thus, each of the first electronic components 3b within the hollow space 1b can dissipate heat relatively quickly, thereby improving the overall heat dissipation performance.

[0109] See Figure 8 This application also provides an electronic control component 100, including a frame 10, an electronic control integration part 30, and a filling part, the filling part being, for example, a second filling part 40.

[0110] The frame 10 includes multiple constituent walls 11, which form an installation space 13, providing a place to house various mechanical and electronic components. The constituent walls 11 can be an integral or separate structure, and can be made of the same or different materials. Optionally, one or more of the constituent walls 11 are configured as heat exchange walls 11a, which exchange heat with a second external cold source 5. The material of the heat exchange wall 11a includes at least one of thermally conductive metal, thermally conductive ceramic, and thermally conductive plastic.

[0111] Combination Figure 1 , Figure 2 and Figure 8The electronic control integration unit 30 is installed within the installation space 13 to protect it. The electronic control integration unit 30 includes a main circuit board 31, an electronic control module 32 mounted on the main circuit board 31, and multiple electrical components 31c1. The electronic control module 32 is mounted on the main circuit board 31 via mounting pins 3a1. A gap, such as a second gap G2, is formed between the main circuit board 31 and the heat exchange wall 11a. The main circuit board 31 is, for example, a power board, and the power board has power terminals 31a, through which the electronic control integration unit 30 can be electrically connected to an external power source.

[0112] The electronic control module 32 includes a housing 1, a first filling portion 2, and an electronic component 3. The housing 1 includes multiple component walls 1a forming a hollow space 1b. At least one component wall 1a is configured as a heat-conducting wall 1a1, which includes a first heat-conducting material 1a11 and exchanges heat with a first external cold source 4. The first filling portion 2 includes a second heat-conducting material 2a filled within the hollow space 1b, which makes thermal contact with the first heat-conducting material 1a11. The electronic component 3 is installed within the hollow space 1b and includes a first circuit board 3a, multiple first electronic components 3b mounted on the first circuit board 3a, and mounting pins 3a1. At least some of the first electronic components 3b are embedded within the second heat-conducting material 2a, and the multiple mounting pins 3a1 extend outside the housing 1 and are mounted on the main circuit board 31. Thus, the first electronic components 3b can exchange heat with the first external cold source 4 through the second heat-conducting material 2a and the first heat-conducting material 1a11.

[0113] Continue reading Figure 1 , Figure 2 and Figure 8 The second filling portion 40 includes a third thermally conductive material 41, which fills the second gap G2. Optionally, the second filling portion 40 submerges part or all of the electrical component 31c1. Optionally, the second filling portion 40 submerges part or all of the electronic control module 32. In this way, the electronic control integration unit 30 mounted on the main circuit board 31 can exchange heat with the second external cold source 5 through the third thermally conductive material 41 and the heat exchange wall 11a. Based on this, the electronic control integration unit 30 can dissipate heat through two different heat dissipation paths, thereby improving the heat dissipation performance of the electronic control component 100.

[0114] In some embodiments, the third thermally conductive material 41 is embedded in at least part of the thermally conductive wall 1a1. Based on this, the first electronic component 3b inside the housing 1 can exchange heat with the thermally conductive wall 1a1 through the second thermally conductive material 2a, and the thermally conductive wall 1a1 can exchange heat with the second external cold source 5 through the third thermally conductive material 41 and the heat exchange wall 11a, thereby realizing the transfer of heat from the inside of the housing 1 to the outside of the housing 1.

[0115] In some embodiments, the third thermally conductive material 41 is embedded in at least part of the mounting pin 3a1, so that the electronic control module 32 transfers heat through the mounting pin 3a1 and the third thermally conductive material 41, thereby improving heat dissipation efficiency.

[0116] Combination Figure 1 and Figure 8 Optionally, the housing 1 is provided with a first through hole 1e, and the first circuit board 3a is provided with a plurality of mounting pins 3a1. The mounting pins 3a1 pass through the first through hole 1e and are electrically connected to the main circuit board 31, thereby realizing the mechanical connection and electrical connection between the first circuit board 3a and the main circuit board 31.

[0117] Optionally, the mounting pin 3a1 is soldered to the main circuit board 31, which can both connect the first circuit board 3a to the main circuit board 31 and seal the first through hole 1e of the housing 1 with solder.

[0118] In some embodiments, the material of the first filling portion 2 is the same as the material of the second filling portion 40, that is, the second thermally conductive material and the third thermally conductive material are the same material. In this way, the first filling portion 2 and the second filling portion 40 can be filled synchronously, for example, after the mounting pin 3a1 is soldered to the main circuit board 31, thereby improving efficiency.

[0119] In some embodiments, the thermal conductivity of the third thermally conductive material is greater than that of the second thermally conductive material. Therefore, when the volume of the installation space 13 is greater than the volume of the hollow space 1b, filling the larger installation space 13 with a third thermally conductive material with higher thermal conductivity results in a more rational material layout, higher heat dissipation efficiency, and lower cost.

[0120] In some embodiments, the plurality of constituent walls 11 further include a peripheral wall 12, which surrounds the heat exchange wall 11a to form an installation space 13, thereby protecting the components within the housing 10. Further, the peripheral wall 12 is integrally formed with the heat exchange wall 11a, thereby simplifying the manufacturing process and improving structural strength. Optionally, depending on the design purpose, the material of the peripheral wall 12 may be the same as or different from that of the heat exchange wall 11a. For example, the peripheral wall 12 and the heat exchange wall 11a may be integrally formed from the same thermally conductive material, or they may be integrally formed from two different thermally conductive materials. In an exemplary embodiment, the material of the peripheral wall 12 is an insulating, non-thermally conductive material. Thus, while the heat exchange wall 11a possesses rapid heat exchange capabilities, the peripheral wall 12, formed from an insulating, non-thermally conductive material, can isolate the electronic components inside the housing 10 from the external environment, reducing the risk of short circuits, and is also smaller in weight and lower in cost.

[0121] Combined Figure 9In some embodiments, a gap is provided between the main circuit board 31 and the peripheral wall 12. Exemplarily, a second gap G2 is provided between the main circuit board 31 and the heat exchange wall 11a, and a third gap G3 is provided between the main circuit board 31 and the peripheral wall 12. Both the second gap G2 and the third gap G3 are filled with a third thermally conductive material 41. In this way, the third thermally conductive material 41 can make more sufficient contact with the main circuit board 31 and transfer the heat of the main circuit board 31 away through different paths, thereby improving heat dissipation efficiency. Furthermore, when the third thermally conductive material 41 can be cured, the cured third thermally conductive material 41 can also serve as a fixing structure for the main circuit board 31, preventing the main circuit board 31 from shifting within the frame 10.

[0122] Continue reading Figure 8 In some embodiments, the main circuit board 31 and the heat exchange wall 11a are spaced apart, for example, spaced apart along a third direction D3. The main circuit board 31 has a third side S3 and a fourth side S4 opposite each other along the third direction D3, with the third side S3 being closer to the heat exchange wall 11a than the fourth side S4. Both the third side S3 and the fourth side S4 are filled with a third thermally conductive material 41. In this way, the electronic components on the main circuit board 31 can dissipate heat more effectively.

[0123] Continue reading Figure 8 and Figure 9 In some embodiments, a support platform 16 protrudes from the inner side of the frame 10. The support platform 16 is configured to support the main circuit board 31 and to space the main circuit board 31 and the heat exchange wall 11a along a third direction D3. Based on this, by adjusting the size and position of the support platform 16, the distance between the main circuit board 31 and the heat exchange wall 11a along the third direction D3 can be adjusted, thereby adjusting the thickness of the third thermally conductive material 41 between the second circuit and the heat exchange wall 11a.

[0124] Optionally, the inner side of the frame 10 is provided with a plurality of support platforms 16 at intervals, and each support platform 16 has a support surface 16b for supporting the main circuit board 31. In this way, the stability of the main circuit board 31 can be improved by supporting the main circuit board 31 simultaneously with multiple support surfaces 16b.

[0125] Furthermore, each support platform 16 also has a guide surface 16a connected to the support surface 16b. The guide surface 16a is constructed as a plane, a curved surface, or a combination thereof. The guide surfaces 16a of the multiple support platforms 16 form a guide channel 16a1. The dimension of the end of the guide channel 16a1 near the heat exchange wall 11a is smaller than the dimension of the end of the guide channel 16a1 away from the heat exchange wall 11a. In this way, the main circuit board 31 can more easily enter the guide channel 16a1 and thus contact the support surface 16b. Moreover, since the dimension of the end of the guide channel 16a1 away from the heat exchange wall 11a is larger, the aforementioned third gap G3 can be formed between the main circuit board 31 and the peripheral wall 12 after the main circuit board 31 is installed.

[0126] Alternatively, the support platform 16 and the frame 10 can be integrally formed, which simplifies the process.

[0127] Optionally, the support platform 16 is located at the junction between the heat exchange wall 11a and the peripheral wall 12. In this way, the support platform 16 can also act as a reinforcing rib at the junction of the heat exchange wall 11a and the peripheral wall 12, thereby improving the structural strength of the frame 10.

[0128] See Figure 10 Optionally, an insulating layer 11e is provided on the surface of the heat exchange wall 11a facing the main circuit board 31, for example, by attaching an insulating thermally conductive material. This insulating layer 11e reduces the risk of short circuits between the main circuit board 31 and the electronic components connected to it, and any conductive structures outside the frame 10. Furthermore, with the main circuit board 31's surface facing the heat exchange wall 11a filled with a third thermally conductive material 41, the insulating layer 11e provides double protection, ensuring that creepage distance specifications are met even if the third thermally conductive material 41 is not fully filled.

[0129] Combination Figure 10 and Figure 11 In some embodiments, the frame 10 is provided with a mounting port 13a communicating with the mounting space 13. The electronic control assembly 100 also includes a cover 20, which can be closed with the frame 10 to cover the mounting port 13a. Based on this, after the components in the mounting space 13 are installed, the cover 20 can be closed with the frame 10 to provide protection against corrosion, debris, etc.

[0130] Combined Figure 1In some embodiments, the frame 10 is provided with a first clearance groove 14, and the cover 20 is provided with a second clearance groove 21. When the cover 20 is closed with the frame 10, the first clearance groove 14 and the second clearance groove 21 form a clearance opening 21a, which exposes at least a portion of the heat-conducting wall 1a1 for external heat exchange fluid to flow through. In this way, when the cover 20 is closed with the frame 10, it can protect the components in the installation space 13, and the fins 1a2 can exchange heat with the external environment.

[0131] Combined Figure 12 and Figure 13 In some embodiments, the heat-conducting wall 1a1 is provided with a plurality of spaced-apart fins 1a2. For example, the heat-conducting wall 1a1 is provided with a plurality of spaced-apart fins 1a2 along a third direction D3. The structure and arrangement of the fins 1a2 can be referred to the description of the foregoing embodiments. A first gap G1 is provided between two adjacent fins 1a2, and a plurality of fins 1a2 form a plurality of first gaps G1. The frame 10 is provided with a second ventilation slot 15, which is correspondingly arranged with a portion of the first gaps G1, that is, the second ventilation slot 15 can supply air to a portion of the first gaps G1. The cover 20 covers the frame 10 along a third direction D3. The cover 20 is provided with a third ventilation slot 22, which is correspondingly arranged with another portion of the first gaps G1, that is, the third ventilation slot 22 can supply air to another portion of the first gaps G1. In this way, while the frame 10 and cover 20 provide protection, more airflow can be directed to the fins 1a2 through the second ventilation slot 15 of the frame 10 and the third ventilation slot 22 of the cover 20 to improve heat exchange efficiency.

[0132] Optionally, the number of second ventilation slots 15 can be one or more. When there is only one second ventilation slot 15, one second ventilation slot 15 can be correspondingly arranged with one or more first gaps G1, that is, one second ventilation slot 15 can supply air to one or more first gaps G1 to improve heat exchange efficiency and ensure that the first shell 1c has high structural strength. When there are multiple second ventilation slots 15, each second ventilation slot 15 can be correspondingly arranged with one or more first gaps G1. For example, there are multiple second ventilation slots 15, and multiple second ventilation slots 15 are corresponding one-to-one with multiple first gaps G1 of fins 1a2, so that air can be supplied to fins 1a2 more evenly.

[0133] Optionally, the number of third ventilation slots 22 can be one or more. When there is only one third ventilation slot 22, one third ventilation slot 22 can be correspondingly arranged with one or more first gaps G1, that is, one third ventilation slot 22 can supply air to one or more first gaps G1 to improve heat exchange efficiency and ensure that the first shell 1c has high structural strength. When there are multiple third ventilation slots 22, each third ventilation slot 22 can be correspondingly arranged with one or more first gaps G1. For example, there are multiple third ventilation slots 22, and the multiple third ventilation slots 22 are corresponding one-to-one with the first gaps G1 of multiple fins 1a2, so that air can be supplied to the fins 1a2 more evenly.

[0134] See Figure 11 and Figure 14 In some embodiments, the electronic control assembly 100 further includes a second circuit board 50, one end of which is connected to the main circuit board 31. For example, one end of the second circuit board 50 along a third direction D3 is connected to the main circuit board 31. The cover 20 is provided with a correction part 23, which is configured to limit the offset of the end of the second circuit board 50 along the third direction D3. Thus, during installation, the correction part 23 can correct the end position of the second circuit board 50, aligning the end of the second circuit board 50, such as the end plug-in terminal, with the opening structure of the cover 20. In addition, when the second circuit board 50 is subjected to external force, the limiting effect of the correction part 23 can prevent the second circuit board 50 from offsetting or reduce the amount of offset.

[0135] For example, the second circuit board 50 is provided with a plurality of terminal blocks 51, which are for external connection terminals to be inserted into. The cover 20 is provided with an opening corresponding to the terminal blocks 51 and exposes the terminal blocks 51. In this way, the connection terminals of external components can be inserted and removed from the terminal blocks 51 through the opening of the cover 20. During the process of inserting and removing external connection terminals, a force is exerted on the second circuit board 50, making the second circuit board 50 prone to shaking, displacement, and tilting. In this embodiment, the setting of the correction part 23 can limit the displacement and tilting of the second circuit board 50. At the same time, the end of the second circuit board 50 away from the correction part 23 is fixed to the main circuit board 31 by the heat-conducting material after curing, so that the second circuit board 50 remains stable, thereby aligning the terminal blocks 51 with the opening of the cover 20, which facilitates the insertion and removal operation.

[0136] Continue reading Figure 11 and Figure 14In some embodiments, the correction part 23 includes a correction groove 23a located on the side of the cover 20 facing the main circuit board 31, and one end of the second circuit board 50 away from the main circuit board 31 extends into the correction groove 23a. Thus, when the second circuit board 50 is installed inside the frame 10 and the cover 20 is closed with the frame 10, one end of the second circuit board 50 can be smoothly inserted into the correction groove 23a. Based on this, when the cover 20 is closed, the correction groove 23a can stably correct and limit the second circuit board 50.

[0137] Optionally, the inner surface of the cover 20 is provided with a plurality of corrective teeth, wherein a corrective groove 23a is formed between two corrective teeth. In this way, the corrective groove 23a can correct and limit the second circuit board 50 without damaging the structure of the cover 20 itself, thereby ensuring the structural strength of the cover 20.

[0138] Optionally, the orthodontic teeth and the cover 20 are integrally formed, thereby improving the structural strength of the connection between the cover 20 and the orthodontic teeth and simplifying the manufacturing process.

[0139] Optionally, the dimension of the straightening groove 23a at the end near the inner surface of the cover 20 is smaller than the dimension at the end away from the inner surface of the cover 20. In other words, the width of the straightening groove 23a gradually increases along the direction toward the main circuit board 31. In this way, the second circuit board 50 can more easily enter the straightening groove 23a, improving the convenience of installation operations.

[0140] Optionally, the cover 20 is provided with a plurality of straightening parts 23, which are arranged at intervals along the length of the second circuit board 50. In this way, the plurality of straightening parts 23 can cooperate to limit the second circuit board 50, and the force is distributed along the length, which can reduce the risk of deformation or breakage of the second circuit board 50 due to excessive local stress.

[0141] See Figure 11 In some embodiments, the main circuit board 31 is provided with a plurality of first terminals 31b and a plurality of second terminals 31b1, which are arranged along a second direction D2. The first terminals 31b are, for example, high-voltage terminals, and the second terminals 31b1 are, for example, low-voltage terminals, which can be connected to external components. The cover 20 is provided with a foolproof part 24, a first clearance part 24a, and a second clearance part 24b. When the cover 20 is closed with the frame 10, the first clearance part 24a and the second clearance part 24b are located on opposite sides of the foolproof part 24 along the second direction D2. The first clearance part 24a exposes the first terminal 31b, and the second clearance part 24b exposes the second terminal 31b1. Thus, during installation, the closing direction of the cover 20 can be quickly determined based on the foolproof part 24, thereby improving installation efficiency.

[0142] See Figure 11 , Figure 14 and Figure 15 In some embodiments, the cover 20 and the frame 10 are closed along a third direction D3. One of the cover 20 and the frame 10 is provided with a guide protrusion 25, and the other is provided with a guide groove 26 extending along the third direction D3. Exemplarily, the guide protrusion 25 is provided on the frame 10, and the guide groove 26 is provided on the cover 20. Further, the guide groove 26 is configured to guide the guide protrusion 25 to move along the third direction D3. In this way, the closing of the cover 20 and the frame 10 can be smoother.

[0143] In some embodiments, the guide protrusion 25 has a connecting end 25a connected to the frame 10 and a free end 25b extending out of the frame 10. The dimension of the free end 25b in at least one direction is smaller than the dimension of the connecting end 25a in the corresponding direction. For example, the dimension of the free end 25b in a second direction D2 is smaller than the dimension of the connecting end 25a in a second direction D2, which intersects with a third direction D3. Thus, when the cover 20 is closed with the frame 10, the guide protrusion 25 can more smoothly enter the guide groove 26, thereby accurately guiding the direction of the cover 20's closure.

[0144] Continue reading Figure 11 , Figure 14 and Figure 15 In some embodiments, one of the cover 20 and the frame 10 is provided with a slot 27, and the other is provided with a hook 28. Exemplarily, the slot 27 is located on the frame 10, and the hook 28 is located on the cover 20. The hook 28 engages with the slot 27, and the hook 28 can elastically deform and disengage from the slot 27 under external force. Thus, through the engagement of the hook 28 and the slot 27, the cover 20 and the frame 10 can maintain a more stable closed state. Furthermore, because the hook 28 can elastically deform and disengage from the slot 27 under external force, the operator can open the cover 20 when maintenance is required.

[0145] In some embodiments, at least one of the cover 20 and the frame 10 is provided with a plurality of wire grooves 17, so that the connection wires of the various electronic components can be sorted out through the wire grooves 17.

[0146] Optionally, the wire groove 17 is provided on the outside of the frame 10, and multiple wire grooves 17 are provided at intervals on the outside of the frame 10. In this way, the connecting wire can be constrained on the outer surface of the frame 10 by the cooperation of multiple wire grooves 17, reducing the risk of interference between the connecting wire and other components.

[0147] In practical applications, electronic control components need to be stably fixed in a predetermined location. In exemplary technologies, to improve the installation stability of the electronic control components, multiple plastic clips are typically used to secure them. Furthermore, since the electronic control components require grounding, grounding measures must be implemented, such as installing grounding screws. Therefore, when the electronic control components require maintenance, multiple clips and grounding screws need to be removed. However, the installation location of the electronic control components is often narrow and concealed, with extremely limited operating space and the operating area being outside the visible range. Operators must forcibly remove multiple clips and grounding screws in this inaccessible and confined space, which is inconvenient and can easily lead to destructive disassembly.

[0148] See Figure 10 Based on this, this application provides an electronic control component 100, including a grounding shell, a frame 10, an electronic control integration unit 30, a first connector 11c, and a second connector 11d.

[0149] The frame 10 is provided with an installation space 13, which can provide a place to accommodate various mechanical and electronic components. Optionally, the frame 10 includes a plurality of constituent walls 11, which form the installation space 13. One or more of the constituent walls 11 include a metal plate 11b, on which a first grounding part 11b1 and a second grounding part 11b2 are provided.

[0150] The electronic control integration unit 30 is installed within the installation space 13. The electronic control integration unit 30 includes a main circuit board 31 and an electronic control module 32 installed on the main circuit board 31. The main circuit board 31 is, for example, a power board, which has a power terminal 31a, through which the electronic control integration unit 30 can be electrically connected to an external power source.

[0151] The first connector 11c connects the metal plate 11b to the main circuit board 31 and electrically connects the first grounding portion 11b1 to the main circuit board 31. For example, the main circuit board 31 has a grounding line, the first grounding portion 11b1 includes a first bolt hole or a first bolt post with a first bolt hole, and the first connector 11c includes a first grounding bolt adapted to the first bolt hole. The mechanical and electrical connections between the metal plate 11b and the main circuit board 31 are achieved through the cooperation of the first grounding bolt and the first bolt hole.

[0152] The second connector 11d connects the metal plate 11b to the grounding shell 200a and electrically connects the second grounding portion 11b2 to the grounding shell 200a. Exemplarily, the second grounding portion 11b2 includes a second bolt hole or a second bolt post with a second bolt hole, and the second connector 11d includes a second grounding bolt adapted to the second bolt hole. The mechanical and electrical connections between the metal plate 11b and the grounding shell 200a are achieved through the cooperation of the second grounding bolt and the second bolt hole.

[0153] Thus, the second connector 11d achieves both mechanical and electrical connections between the frame 10 and the grounding shell, while the first connector 11c achieves both mechanical and electrical connections between the main circuit board 31 and the frame 10. This also achieves electrical connections between the electronic control integration unit 30 and the grounding shell, thereby grounding and mechanically fixing the electronic control component 100. This improves the assembly stability and electrical safety of the electronic control component 100, and the connection structure is simple, allowing for convenient and quick assembly and disassembly. Therefore, when maintenance of the electronic control component 100 is required, it can be removed from the grounding shell by disassembling the second connector 11d, making the operation convenient, quick, and less likely to cause destructive disassembly.

[0154] Continue reading Figure 10 In some embodiments, the first grounding portion 11b1 includes a first bolt post protruding from the metal plate 11b towards the main circuit board 31. The cross-sectional shape of the first bolt post is, for example, circular, elliptical, triangular, quadrilateral, pentagonal, hexagonal, or a combination thereof. The first bolt post has a first bolt hole, and the first connector 11c includes a first grounding bolt adapted to the first bolt hole. Thus, the structure of the first grounding portion 11b1 is simple and easy to assemble and disassemble. Furthermore, since the first grounding portion 11b1 protrudes relative to the metal plate 11b, the structural strength of this part is relatively high, and the bolt hole is designed on this basis to prevent damage to the frame 10 structure.

[0155] Optionally, the structure of the second grounding portion 11b2 may refer to the structure of the first grounding portion 11b1. It should be noted that the structure of the second grounding portion 11b2 may be the same as or different from the structure of the first grounding portion 11b1.

[0156] In some embodiments, one end of the first bolt post is connected to the metal plate 11b, and the other end abuts against the main circuit board 31. In this way, the first grounding part 11b1 not only serves as a grounding and mechanical fixing function, but also as a supporting function, so that the main circuit board 31 is supported more stably.

[0157] In some embodiments, the end face of the first bolt post is flush with the support surface 16b of the support platform 16. In this way, the support platform 16 and the first bolt post simultaneously support the main circuit board 31, thereby improving the stability of the main circuit board 31.

[0158] Optionally, multiple support platforms 16 are arranged around the first bolt post. In this way, both the outer and middle areas of the main circuit board 31 can be supported.

[0159] Combination Figure 1 , Figure 8 and Figure 10In some embodiments, the electronic control module 32 includes a housing 1, a first filling portion 2, and an electronic component 3. The housing 1 includes multiple component walls 1a, which form a hollow space 1b. At least one component wall 1a is configured as a heat-conducting wall 1a1, which includes a first heat-conducting material 1a11 that exchanges heat with an external cold source. The first filling portion 2 includes a second heat-conducting material 2a filled in the hollow space 1b, which is in thermal contact with the first heat-conducting material 1a11. The electronic component 3 is installed in the hollow space 1b and includes a first circuit board 3a and multiple first electronic components 3b installed on the first circuit board 3a. At least some of the first electronic components 3b are embedded in the second heat-conducting material 2a.

[0160] The electronic control assembly 100 also includes a second filling portion 40. The second filling portion 40 includes a third thermally conductive material 41 filled within the mounting space 13, with the third thermally conductive material 41 embedding at least a portion of the thermally conductive wall 1a1. A portion or all of the metal plate 11b of the frame 10 is reused as a heat exchange wall 11a, with a second gap G2 formed between the heat exchange wall 11a and the main circuit board 31, and the third thermally conductive material 41 fills the second gap G2. The third thermally conductive material 41 exchanges heat with an external cold source through the heat exchange wall 11a. Based on this, the first electronic component 3b inside the housing 1 can exchange heat with the thermally conductive wall 1a1 through the second thermally conductive material 2a, and the thermally conductive wall 1a1 can exchange heat with an external cold source through the third thermally conductive material 41, thereby realizing the transfer of heat from the inside of the housing 1 to the outside of the housing 1. Furthermore, the metal plate 11b serves as both a grounding medium and a heat dissipation medium, simplifying the overall structure of the electronic control assembly 100, improving safety performance, and enhancing heat dissipation performance.

[0161] Optionally, the electrical component 31c1 includes a second electronic component 31c disposed on the main circuit board 31. Exemplarily, one or more second electronic components 31c are disposed on the side of the main circuit board 31 facing away from the metal plate 11b. Each second electronic component 31c has a second terminal pin that penetrates the main circuit board 31 and extends to the side of the main circuit board 31 facing the metal plate 11b. The main circuit board 31 has a potting hole 31d, and both the side of the main circuit board 31 facing the metal plate 11b and the side facing away from the metal plate 11b are filled with a third thermally conductive material 41. The third thermally conductive material 41 within the potting hole 31d connects the third thermally conductive materials 41 on both sides. Thus, the second electronic component 31c has multiple heat conduction paths. For example, heat is transferred to the third heat conduction material 41 on the side of the main circuit board 31 facing the metal plate 11b through the second terminal pin. Alternatively, heat is transferred to the third heat conduction material 41 on the side of the main circuit board 31 facing the metal plate 11b through the third heat conduction material 41 on the side of the main circuit board 31 away from the metal plate 11b and the third heat conduction material 41 in the potting hole 31d.

[0162] Continue reading Figure 10 In some embodiments, an insulating layer 11e is provided on the side of the metal plate 11b facing the main circuit board 31. The insulating layer 11e increases the creepage distance between the main circuit board 31 and its connected second electronic component 31c and the metal plate 11b, improving safety performance. The thickness of the insulating layer 11e can be set according to the safe creepage distance specified in relevant installation regulations. It is understood that when the third thermally conductive material 41 filling the mounting space 13 is an insulating material, the third thermally conductive material 41 can also increase the creepage distance. In this case, the insulating layer 11e and the second filling portion 40 provide dual protection. The insulating layer 11e reduces the risk of insufficient filling of the third thermally conductive material 41, leading to poor insulation.

[0163] Optionally, the insulating layer 11e includes an insulating and thermally conductive material. Thus, the insulating layer 11e provides both spacing insulation and thermal conductivity, further enhancing heat dissipation performance.

[0164] Continue reading Figure 10 In some embodiments, the metal plate 11b includes a heat exchange wall 11a located on the inner side of the peripheral wall 12 and an extension wall 11a1 located on the outer side of the peripheral wall 12. In other words, a portion of the metal plate 11b is reused as the heat exchange wall 11a, and another portion is reused as the extension wall 11a1. The second grounding portion 11b2 is disposed on the extension wall 11a1, that is, the second grounding portion 11b2 is disposed on the outer side of the peripheral wall 12. Based on this, the operator can perform disassembly and assembly operations on the second grounding portion 11b2 from the outside of the frame 10, making the disassembly and assembly between the frame 10 and the grounding shell 200a more convenient.

[0165] See Figure 16 This application also provides an air conditioning device 1000, including an electrical control support 200 and an electrical control component 100 as described in the above embodiments, wherein the electrical control component 100 is mounted on the electrical control support 200.

[0166] In some embodiments, the electronic control support 200 is reused as a grounding shell 200a. In this way, the electronic control support 200 serves to both support the electronic control assembly 100 and connect the electronic control assembly 100 to the ground, simplifying the overall structure.

[0167] Combination Figure 6 and Figure 16 In some embodiments, the air conditioning unit 1000 is an outdoor unit 1000a, which includes an outer panel 300a, a middle partition 400a, an outdoor heat exchanger 500a, an outdoor fan 600a, and a compressor 700a.

[0168] The outer panel 300a has a hollow cavity inside to house and protect the various components of the outdoor unit 1000a. The outer panel 300a is provided with a first outdoor air inlet 300a1, a second outdoor air inlet 300a2, and an outdoor air outlet 300a4. To prevent debris from entering the outer panel 300a, an air inlet grille can be provided at each air inlet, and an air outlet grille can be provided at each air outlet. Exemplarily, the outer panel 300a has a bottom panel and a top panel facing each other, and a side panel surrounding and connected between the bottom panel and the top panel. The side panel includes, for example, a first side panel, a second side panel, a third side panel, and a fourth side panel connected in sequence, with the first side panel opposite to the third side panel, the second side panel opposite to the fourth side panel, and the first side panel connected to the fourth side panel.

[0169] The number of first outdoor air inlets 300a1 can be one or more. When there are multiple first outdoor air inlets 300a1, they can be installed on the same side panel or on different side panels. Furthermore, when multiple first outdoor air inlets 300a1 are installed on different side panels, they can be installed on adjacent side panels or opposite side panels. The number and arrangement of second outdoor air inlets 300a2 can refer to the number and arrangement of first outdoor air inlets 300a1, and the number and arrangement of outdoor air outlets 300a4 can also refer to the number and arrangement of first outdoor air inlets 300a1. It should be noted that the number and arrangement of the second outdoor air inlet 300a2 and the number and arrangement of the outdoor air outlet 300a4 can refer to the number and arrangement of the first outdoor air inlet 300a1. It is not required that the number and arrangement of the second outdoor air inlet 300a2 and the number and arrangement of the outdoor air outlet 300a4 must be the same as the number and arrangement of the first outdoor air inlet 300a1.

[0170] For example, there are multiple first outdoor air inlets 300a1, each located on two adjacent side panels, such as on the first side panel and the second side panel. There is one outdoor air outlet 300a4, located on opposite side panels as one of the first outdoor air inlets 300a1, for example, on the fourth side panel. There is one second outdoor air inlet 300a2, located on the second side panel. In other words, the second outdoor air inlet 300a2 and one of the first outdoor air inlets 300a1 are located on the same side panel, and the second outdoor air inlet 300a2 and the outdoor air outlet 300a4 are located on opposite side panels. Based on this, good convection can be formed. When the bottom panel and top panel are arranged opposite each other in the vertical direction, the outdoor air outlet 300a4 is located on the side, that is, the air outlet mode of the outdoor unit 1000a is side air outlet.

[0171] Continue reading Figure 16 A partition 400a is located within the outer panel 300a, dividing the internal space of the outer panel 300a into a heat exchange space 300a5 and a mechanical space 300a6. A first outdoor air inlet 300a1 and an outdoor air outlet 300a4 are located corresponding to the heat exchange space 300a5, and a second outdoor air inlet 300a2 is located corresponding to the mechanical space 300a6. The partition 400a has an outdoor ventilation opening 400a1 connecting the heat exchange space 300a5 and the mechanical space 300a6. An outdoor heat exchanger 500a and an outdoor fan 600a are located within the heat exchange space 300a5, and a compressor 700a is located within the mechanical space 300a6. The electronic control component 100 is installed in the partition 400a and located within the mechanical space 300a6. The second filling part 40 exchanges heat with the partition 400a, or the second filling part 40 exchanges heat with the heat dissipation structure installed in the partition 400a. Based on this, the electronic control component 100 can exchange heat with the partition 400a or the heat dissipation structure installed in the partition 400a through the second filling part 40, and the partition 400a can be cooled by the airflow in the heat exchange space 300a5; furthermore, the electronic control component 100 can also be cooled by the airflow between the second outdoor air inlet 300a2 and the outdoor air outlet 300a4, thereby improving heat dissipation performance.

[0172] In some embodiments, the partition 400a serves both to separate the internal space of the panel and to install and fix the power control component 100.

[0173] For example, combining Figure 10 and Figure 16In an optional embodiment, the partition 400a is reused as the electrical control support 200, and the heat exchange wall 11a abuts against the partition 400a. Thus, the partition 400a directly exchanges heat with the heat exchange wall 11a, simplifying the structure and providing higher heat dissipation efficiency. In this case, the partition 400a is one implementation of the second external cold source 5 in the aforementioned embodiments. Alternatively, the partition 400a can also serve as an implementation of the grounding shell 200a.

[0174] For example, combining Figure 10 and Figure 17 In another optional embodiment, a support plate 400a2 is provided on the partition 400a, and the support plate 400a2 is configured as an electrically controlled support member 200. Further, the support plate 400a2 is integrally formed with the partition 400a, or the support plate 400a2 and the partition 400a are fixed by welding, bonding, snap-fitting, threaded connection, or other methods. In this way, the partition 400a directly exchanges heat with the support plate 400a2, and the support plate 400a2 can exchange heat with the partition 400a or the circulating gas. Based on this, the shape, size, and fixing position of the support plate 400a2, as the electrically controlled support member 200, can be adjusted more flexibly according to the spatial layout. In this case, the support plate 400a2 is one implementation of the second external cold source 5 in the aforementioned embodiment. Additionally, the support plate 400a2 can also be used as an implementation of the grounding shell 200a.

[0175] See Figure 16 Optionally, in the scheme where the partition plate 400a is reused as the electrical control support component 200, the partition plate 400a can also be further reused as a grounding shell.

In other words, the outdoor electrical box 800a simultaneously serves as a protective shell, grounding shell, and heat exchange wall 11a for the electronic control component 100. This achieves grounding of the electronic control component 100 and the outdoor unit 1000a, while improving heat dissipation performance and simplifying the overall structure. Optionally, the outer panel 300a can be reused as a grounding shell, providing both an installation reference for the electronic control component 100 and a grounding connection, thereby simplifying the structure.

[0183] Optionally, outdoor electrical box 800a is provided with outdoor ventilation openings 400a1 on both sides of the vertical direction D4, so that the space inside the outdoor electrical box 800a is connected with the space inside the outer panel 300a, thereby enabling the airflow circulation process of the outdoor unit 1000a to more efficiently remove the heat from the electronic control components 100.

In this way, the first through hole 300b4 and the second through hole 300b5 can connect the indoor electrical box 600b with the internal space of the inner casing 300b, so that the heat dissipation efficiency of the electronic control component 100 is higher. In addition, the first through hole 300b4 and the second through hole 300b5 can also serve as wiring holes to facilitate the electrical connection of components in different cavities. For example, components such as the indoor expansion valve 700b and the indoor temperature sensor are located in the indoor air outlet cavity 300b2. The connecting wires of the indoor expansion valve 700b and the indoor temperature sensor can be electrically connected to components such as the indoor drive motor 800b located in the indoor air inlet cavity 300b1 through the wire hole.

Based on this, the internal structure is simplified, and the circulating airflow of the indoor unit 1000b is fully utilized to dissipate heat from the electronic control components 100.
