Description

Technical Field

[0001] This invention relates to the field of pump unit technology, and more specifically, to a pump control box assembly and a pump assembly. Background Technology

[0002] In a pump system, the pump assembly typically includes components such as a printed circuit board (PCB), a control box, and a base. The PCB is installed inside the control box. To ensure the electrical safety of the PCB, it is crucial to keep the inside of the control box dry, effectively preventing the formation of internal condensation. However, in practical operation, especially in typical heat pump applications, the ambient temperature is often significantly higher than the operating temperature of the pump medium. This makes it easier for condensation to form inside the control box, posing a serious threat to the electrical safety and operational reliability of the PCB.

[0003] To suppress condensation in the control box, common industry solutions include: 1) transferring the heat generated by the control board to the outside air via the control box housing to lower the internal temperature, but this has limited heat dissipation efficiency; 2) adding a heat insulation plate between the control box and the base to effectively block heat transfer from the base to the control box, reducing the temperature difference and lowering the risk of condensation. However, installing a separate heat insulation plate between the control box and the base requires significant space, inevitably increasing the overall size of the pump unit. This hinders miniaturization and compact design, limiting its application in space-constrained installation scenarios.

[0004] Therefore, how to further optimize the design while avoiding the need to maintain a compact pump unit structure, and more reliably prevent condensation from forming inside the control box, is a problem that the industry has always been concerned about. Summary of the Invention

[0005] 1. The technical problem that the invention aims to solve In view of the problem that condensation water is easily generated in the pump control box of the prior art, which affects the electrical safety, the present invention aims to provide a pump control box assembly and a pump assembly. By optimizing the structure of the control box, the heat dissipation performance can be effectively improved, the generation of condensation water can be reduced, and the compact layout of the pump assembly can be ensured, reducing space occupation and improving the convenience and reliability of application.

[0006] 2. Technical Solution To achieve the above objectives, the technical solution provided by the present invention is as follows: A pump control box assembly of the present invention includes: The control box is made of metal; the bottom of the control box has a mounting hole for connecting to the inner cavity, which is used for mounting to a mounting base. The inner panel module is made of plastic. The control box cavity has a first area and a second area. The inner panel module covers the bottom wall of the first area and at least covers the mounting hole of the base. An electrical connector is provided on the inner panel module at a position corresponding to the mounting hole of the base. The electrical connector is used to electrically connect the control board and the base. Multiple sets of heat dissipation fins are spaced apart on the outer wall of the control box, corresponding to the second area inside that is not covered by the inner panel module.

[0007] This invention incorporates a plastic inner panel module within a metal control box. This plastic module provides insulation and covers the upper end of the base, reducing axial height space requirements, creating a compact layout, and effectively preventing direct heat transfer from the base to the control box. Areas not covered by the inner panel module are rapidly cooled by metal heat dissipation fins on the control box walls and exterior, effectively lowering the internal temperature and mitigating condensation.

[0008] The present invention provides a pump control box assembly, comprising: a control box made of metal; the bottom of the control box is provided with a base mounting hole and a through hole communicating with the inner cavity; the base mounting hole is used for fitting and installing with a base; The inner panel module is made of plastic. It is located at the bottom of the control box cavity and at least covers the area where the mounting holes of the base are located. The inner panel module is equipped with electrical connectors and external electrical interfaces. The electrical connectors are located in the area where the mounting holes of the base are located and are used to electrically connect the control board and the base. The external electrical interfaces are exposed in the control box through the through holes and are used to electrically connect the control board to external circuits. Multiple sets of spaced heat dissipation fins are provided on the outer wall of the control box in the positions corresponding to the areas of the interior not covered by the inner panel module.

[0009] This invention not only utilizes the inner panel module to cover the mounting holes of the base to create a heat insulation effect, but also, in conjunction with the externally designed metal heat dissipation fins, effectively dissipates heat from the control box. Simultaneously, it integrates electrical connectors and external electrical interfaces on the inner panel module, using it as a wiring adapter module to achieve internal electrical connections between the control board and the base, as well as external electrical connections between the control board and external wiring. Users can directly connect external wires, making operation more convenient. Furthermore, it eliminates the need for separate external interfaces on the control box, reducing the number of components, lowering production costs, and improving the compatibility and versatility of the control box. The external electrical interface can specifically be a power connector or other external interfaces.

[0010] Furthermore, it also includes an electronic control board, which has large heat source components and small heat source components distributed on it. The large heat source components are distributed in the areas not covered by the inner board modules, while the small heat source components are distributed in the areas where the inner board modules are located.

[0011] This invention distributes large and small heat source components in separate, concentrated areas. The high-heat areas of the control board can quickly transfer heat to the outside using the control box and external heat dissipation fins. The low-heat areas are blocked by the inner board modules, and heat can also be gradually transferred to areas not covered by the inner board modules for external dissipation. Furthermore, concentrating the large heat source components in areas not covered by the inner board modules adapts to different space sizes, avoiding the impact of the internal inner board modules on space utilization, and achieving a rational and compact layout within the control box.

[0012] Furthermore, the through-holes and heat dissipation fins on the control box are located at both ends along the length of the control box, with mounting holes for the base distributed between the through-holes and the heat dissipation fins. In practice, the size of the control box is relatively limited. Placing the external power interface at one end and the heat dissipation fins at the other end not only meets the needs for convenient installation and distribution of various components and operating space, but also maximizes the heat dissipation performance of the control box within the limited space, improving the situation of internal condensation while maintaining a compact layout.

[0013] Furthermore, the end of the control box has an inwardly recessed area, with a through-hole formed within this recessed area. One end of the inner plate module has a corresponding outward protrusion facing this recessed area, with external power interfaces distributed on the outward protrusion. This design ensures that while the external power interfaces are exposed, there is no significant height difference between them and the bottom wall of the control box, facilitating user wiring operations and preventing any impact on the assembly of nearby mounting bases.

[0014] Furthermore, the inner panel module has multiple fixing holes around its perimeter for fixed installation with the control box, ensuring stable installation of the inner panel module; and / or, the inner panel module also has positioning holes, and the control box has corresponding positioning posts that match the positioning holes, ensuring accurate positioning.

[0015] Furthermore, the inner panel module has an upwardly protruding inner protrusion at a position corresponding to the mounting hole of the base, and a certain recessed area is formed between the bottom surface of the inner protrusion and the mounting hole of the base; electrical connectors are distributed on the inner protrusion. The setting of the inner protrusion not only helps to improve the structural strength of the inner panel module, but also optimizes the space between the recessed area formed on the bottom surface and the base assembled below, improving the installation convenience and compactness of the base and control box.

[0016] Furthermore, the inner panel module has an upwardly extending first columnar portion and a second columnar portion on the side facing the electronic control board. The first columnar portion and the second columnar portion are located on opposite sides of the width direction of the inner panel module, and closer to the end of the inner panel module that is furthest from the protruding portion in the length direction. The first columnar portion and the second columnar portion can be used to position the electronic control board, improving the installation accuracy and positional stability of the electronic control board.

[0017] Furthermore, the area inside the control box not covered by the inner board module is also equipped with a heat dissipation protrusion. The heat dissipation protrusion contacts at least some of the large heat source components on the electronic control board to dissipate heat, further promoting the transfer of heat to the outside.

[0018] The present invention also provides a pump assembly having the pump control box assembly as described above, and further including a base, the base being adapted to be mounted on the base mounting hole of the control box, and heat dissipation fins at the bottom of the control box surrounding the outside of the base.

[0019] The pump assembly of the present invention integrates the inner plate module into the control box, which not only makes the overall structure layout more compact and centralized, which is conducive to miniaturization and compact design, but also promotes rapid internal heat dissipation and reduces the generation of condensate inside the control box by utilizing the reasonable layout and synergistic optimization within the control box.

[0024] The present invention will be further described below with reference to embodiments.

[0025] Example Combination Figures 1 to 8 As shown, this embodiment provides a pump assembly including a control box assembly and a base 200. The control box assembly specifically includes a control box 100, an electrical control board 110 located inside the control box 100, and an inner panel module 300. The bottom end of the control box 100 has a base mounting hole 105 communicating with the inner cavity. The base 200 is fitted and installed with the control box 100 through the base mounting hole 105. Specifically, bolt holes are provided around the base mounting hole 105, allowing the control box 100 to be fixed to the axial end of the base 200 using bolts. The base mounting hole 105 directly communicates with the inner cavity of the control box 100, providing space for the base 200 to be inwardly fitted at the end during assembly, reducing the axial assembly height between the two and achieving a compact overall layout.

[0026] Specifically, in this embodiment, the inner cavity of the control box 100 has a first region and a second region, so as to... Figure 4 As shown in the diagram, the inner panel module 300 covers the bottom wall of the first area and at least covers the mounting hole 105. An electrical connector 308 is provided on the inner panel module 300 at a position corresponding to the mounting hole 105, for electrically connecting the electrical control board 110 located above the inner panel module 300 and the base 200 located below the control box 100. The second area inside the control box 100 is the area not covered by the inner panel module 300. Multiple sets of heat dissipation fins 101 are provided on the outer wall of the control box 100 at intervals at positions corresponding to the second area inside. Specifically, it is preferable to provide heat dissipation fins 101 at the bottom of the outer wall of the control box 100.

[0027] In practice, the inner panel module 300 is made of plastic, which can effectively block heat transfer. It is preferably manufactured using an integral injection molding method. The control box 100 and the external heat dissipation fins 101 are generally made of metal, which can dissipate heat quickly. In this embodiment, the plastic inner panel module 300 is placed inside the control box 100, covering the bottom wall and completely covering the mounting hole 105 of the base, that is, covering the upper part of the end of the base 200. This effectively prevents the heat of the base 200 from being directly transferred to the inside of the control box 100. In practice, it is preferable to further seal the area of ​​the mounting hole 105 at the assembly position of the base 200 and the control box 100. The area not covered by the inner panel module 300 is quickly dissipated through the heat dissipation fins 101 provided on the wall and outside of the control box 100, thereby effectively reducing the internal temperature of the control box 100 and improving the problem of internal condensation.

[0028] In practice, to achieve a miniaturized and compact design, the space of the control box 100 is relatively limited. Therefore, the inner panel module 300 is designed to cover only a portion of the control box 100's interior area rather than the entire area, saving internal space and enabling effective heat insulation in the first area and rapid heat dissipation in the second area, thus improving the condensation problem. Heat from the first area can also be better transferred to the second area for heat dissipation.

[0029] In this embodiment, the control box assembly, in addition to effective heat insulation using the inner panel module 300, can also integrate electrical adapter components on the inner panel module 300, enabling the inner panel module 300 to integrate circuit adapter functions. Specifically, the bottom of the control box 100 is also provided with a through hole 103 communicating with the inner cavity. In addition to the aforementioned electrical connector 308, the inner panel module 300 is also provided with an external electrical interface 304. The external electrical interface 304 passes through the through hole 103 and is exposed to the control box 100. Figure 1 and Figure 5 As shown, at least a portion of the inner panel module 300 is exposed to the control box 100 through the through hole 103. An external power interface 304 is provided on this exposed area of ​​the inner panel module 300. This external power interface 304 is electrically connected to the internal electronic control board 110, specifically as follows: Figure 5 and Figure 7 As shown, the external power interface 304 has an internal connection part 305, such as a pin, on the inner side of the control box 100, which can be electrically connected to the control board 110.

[0030] In this embodiment, an external power interface 304, specifically a power supply interface, is formed on the inner board module 300, and this external power interface 304 is exposed to the control box 100. Users can directly connect wires to the external power interface 304, making operation more convenient. Furthermore, integrating it into the inner board module 300 results in a more compact structure, eliminating the need for a separate external interface on the control box 100, reducing the number of components, lowering production costs, and improving the adaptability and versatility of the control box 100. When it is necessary to change or add / remove the external power interface 304, since it is integrated into the independently set inner board module 300, only the inner board module 300 needs to be adjusted, without replacing the entire control box 100. This enhances the adaptability and versatility of the control box 100 and helps control production and design costs. Moreover, this design completely isolates the external power interface 304 from the base 200, effectively preventing heat from the base 200 from being transferred to the control box 100 through the external power interface 304. In practice, the sealing elements between the inner plate module 300 and the through hole portion 103 can be further optimized for sealing, such as using a sealing ring, which will not be elaborated here.

[0031] Preferably, in this embodiment, the distribution of components on the electronic control board 110 is adaptively adjusted, combined with... Figure 3 As shown, the control board 110 is installed in the cavity of the control box 100 and located above the inner board module 300. Numerous components are distributed on the control board 110, including high heat source components, such as high-power modules and chips, which are the main heat sources and will generate a lot of heat during long-term operation. It also includes low heat source components, such as various detection and interface devices, which generate less heat.

[0032] In this embodiment, large and small heat source components are distributed in separate areas. Large heat source components are mainly located at one end of the control board 110, corresponding to the second area within the control box 100. Small heat source components are mainly located at the other end of the control board 110, corresponding to the first area within the control box 100, i.e., the area where the inner board module 300 is located. In this way, the large heat-generating area of ​​the control board 110 can directly and quickly transfer heat to the outside using the control box 100 and the outer heat dissipation fins 101. The heat in the small heat-generating area is blocked by the inner board module 300 and can also gradually transfer heat to the second area for dissipation. More preferably, a metal heat dissipation protrusion 104 is also provided in the second area within the control box 100. The heat dissipation protrusion 104 contacts at least some of the large heat source components on the control board 110 for heat dissipation. Specifically, thermally conductive silicone can be used to cover the heat dissipation protrusion 104 to further accelerate heat dissipation.

[0033] In practice, the large heat source components on the control board 110 are generally large in size, while the small heat source components are relatively small. Concentrating the large heat source components in the second area can also adapt to the size distribution of the space, avoid the impact of the internal board module 300 on the space occupation, realize the reasonable layout and compact distribution of the internal space of the control box 100, avoid the control box 100 being too large, and achieve the compact distribution of the whole machine.

[0034] Furthermore, combining Figure 6 As shown, the through-hole 103 and heat dissipation fin 101 on the preferred control box 100 are located at both ends of the control box 100 along its length, and the mounting holes 105 are distributed between the through-hole 103 and the heat dissipation fin 101. The through-hole 103 and the mounting holes 105 correspond to the positions of the first internal region. To ensure a compact design, the size of the control box 100 is relatively limited in practice. In this embodiment, the mounting base 200 is installed in the middle region of the control box 100. A through-hole 103 is provided on the outer side of one end to accommodate the external power interface 304 for easy wiring, and a heat dissipation fin 101 is provided on the other end to accelerate heat dissipation. This satisfies the needs for convenient installation and distribution of components and operating space, and also fully improves the heat dissipation performance of the control box 100 within a limited space, improving the situation of internal condensation while maintaining a compact layout.

[0035] Furthermore, combining Figure 6 As shown, in practice, the through-hole portion 103 can be designed as follows: the end of the control box 100 opposite to the side where the heat dissipation fin 101 is located has an inwardly recessed area, and the through-hole portion 103 is opened in this recessed area, such as... Figure 8 As shown, one end of the inner plate module 300 is provided with an external protrusion 310, which protrudes toward the concave area where the through hole portion 103 is located, such as... Figure 1 As shown, the external power interface 304 is distributed on the protruding part 310. This arrangement ensures that even when the external power interface 304 is exposed, there is no significant height difference between it and the bottom wall of the control box 100. It maintains a roughly consistent height with the bottom wall of the control box 100, resulting in a more aesthetically pleasing structure, facilitating user wiring operations, and avoiding any impact on the assembly of the nearby mounting base 200. It also helps save space inside the control box 100, making the layout more compact and rational. In practice, a further preferred design is that the recessed area where the through-hole 103 is located extends to the side wall of the control box 100, forming an opening. Figure 1 As shown, the control box 100 is open at both the bottom and sides, making it easier to connect the external power interface 304.

[0036] Furthermore, the inner panel module 300 has an upwardly protruding inner protrusion 309 corresponding to the mounting hole 105 of the base, and a certain recessed area is formed between the bottom surface of the inner protrusion 309 and the mounting hole 105 of the base; electrical connectors 308 are distributed on the inner protrusion 309. The setting of the inner protrusion 309 not only forms folds and bends on the plate of the inner panel module 300 to improve structural strength, but also optimizes the space between the recessed area formed on the bottom surface and the base 200 assembled below, ensuring the ease of installation and compactness of the base 200 and the control box 100.

[0037] To achieve the fixed installation of the inner board module 300 within the control box 100, combined with Figure 7 and Figure 8 As shown, further, the inner panel module 300 has multiple fixing holes 307 around its perimeter for fixed installation with the control box 100; specifically, five fixing holes 307 can be provided at the four corners and the center of the inner panel module 300, and bolts can be used to lock the inner panel module 300 to the bottom wall of the control box 100. Furthermore, the inner panel module 300 also has positioning holes 306, and the control box 100 has corresponding positioning posts 102 that fit into the positioning holes 306 to ensure accurate positioning. The positioning holes 306 can be specifically located in the center of the inner panel module 300, such as near the fixing holes 307 in the center.

[0038] Furthermore, the inner panel module 300 is provided with an upwardly extending first columnar portion 301 and second columnar portion 302 on the side facing the electronic control board 110; the first columnar portion 301 and the second columnar portion 302 are respectively located on both sides of the width direction of the inner panel module 300, and are located at the end of the inner panel module 300 closer to the second region in the length direction, that is, closer to the end of the inner panel module 300 further away from the outer protrusion 310 in the length direction. Specifically, the first columnar portion 301 and the second columnar portion 302 can be integrally injection molded with the inner plate module 300 using a hollow columnar structure. The two sides of the electronic control board 110 in the width direction are provided with through holes for the first columnar portion 301 and the second columnar portion 302 to pass through. In this way, the first columnar portion 301 and the second columnar portion 302 can be used to position the electronic control board 110, thereby improving the installation accuracy and positional stability of the electronic control board 110. In practice, the control box 100 also has a top cover, which can be selected to press down on the first columnar portion 301 and the second columnar portion 302 on both sides, making the position of the inner plate module 300 more stable and reliable.

[0039] In this embodiment, the pump assembly integrates the inner board module 300 into the control box 100. This not only makes the overall structure layout more compact and centralized, facilitating miniaturization and compact design, but also promotes rapid internal heat dissipation through the reasonable layout and synergistic optimization within the control box 100, reducing the generation of condensate inside the control box 100 and ensuring electrical safety during long-term application. Furthermore, the integration of interface structures on the inner board module 300 helps improve the versatility of the control box 100, reduce production costs, and has significant practical implications.

[0040] The present invention and its embodiments have been described above illustratively. This description is not restrictive and is merely one embodiment of the present invention, and is not actually limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
