TECHNICAL FIELD

[0001] The present application relates to the technical field of electric control boxes, and particularly relates to an electric control box integrated with a heat dissipation module. BACKGROUND

[0002] In the prior art, a conventional variable frequency drive module of a heat pump unit generally adopts a structure design combining a PCB board and a fluorine cooling module. The module is usually composed of two parts, the upper part being a PCB board responsible for control and processing of circuits, and the lower part being a fluorine cooling module for effectively dissipating heat of the heating elements on the PCB board through refrigerant. This design ensures stable operation of the heat pump unit to a certain extent, but also has significant technical limitations and improvement space.

[0003] Firstly, from the cost perspective, since the fluorine cooling module adopts thick aluminum plate material, the production cost is increased, and the overall cost is also increased. This high cost limits the market competitiveness of the heat pump unit to a certain extent.

[0004] Secondly, the convenience of installation and replacement is also a big challenge faced by the current design. The fluorine cooling module is heavy, which not only increases the difficulty in the installation process, but also makes it particularly difficult to replace the variable frequency drive module in the after-sales maintenance process. Especially in the case of emergency repair, this inconvenience may cause the extension of service response time and affect user experience. CONTENT OF THE INVENTION

[0005] The purpose of the embodiment of the present application is to provide an electric control box integrated with a heat dissipation module, aiming to solve the problems of high cost, difficult installation and replacement and the like in the prior art, so as to provide a more efficient, economical and easy-to-maintain heat pump unit solution.

[0006] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0007] On the one hand, an electric control box integrated with a heat dissipation module is provided, comprising: a mounting seat, a cooling pipe, a cover plate and a circuit board, a recess is formed in the mounting seat, a first arc-shaped groove for mounting the cooling pipe is arranged in the recess, the cover plate is arranged on the recess and is flush with a mounting surface of the mounting seat for mounting the circuit board, the circuit board is mounted on the mounting surface and at least partially located above the cover plate.

[0008] Further, the recess comprises a first groove body and second groove bodies located on both sides of the first groove body, and the first arc-shaped groove is arranged on the first groove body.

[0009] Further, the vertical height of the second groove body is higher than the vertical height of the first groove body.

[0010] Furthermore, the cover plate includes a plate body and a protrusion protruding from the bottom of the plate body. The protrusion is positioned opposite to the first groove body, and a second arc-shaped groove is formed on the protrusion to cooperate with the first arc-shaped groove to define the cooling pipe.

[0011] Furthermore, the plate is locked to the second groove by fasteners.

[0012] Furthermore, the second groove is provided with a plurality of first locking holes, and the plate is provided with second locking holes that correspond one-to-one with the first locking holes.

[0013] Furthermore, multiple first reinforcing members are provided at intervals between the first groove and the second grooves on both sides.

[0014] Furthermore, the bottom of the mounting base is provided with multiple second reinforcing members.

[0015] Furthermore, a clearance structure is provided at one end of the groove along its length to allow the cooling pipe to pass through.

[0016] Furthermore, the cooling pipe can be connected to a cold water supply device or a refrigerant pipeline.

[0017] The beneficial effects of this application are as follows: First, it effectively solves the problem of high cost and high manufacturing cost of traditional heat pump unit inverter drive modules. By simplifying the heat dissipation structure, it reduces production costs and improves market competitiveness. Second, this design significantly improves the convenience of installation and replacement. Due to the tight integration of the cooling pipes and the mounting base, as well as the protective function of the cover plate, the entire electrical control box structure is more compact and stable, facilitating installation and disassembly. During after-sales maintenance, replacing the electrical control box also becomes simpler and faster, greatly shortening service response time and improving user experience. Furthermore, this design significantly improves the heat dissipation efficiency of the electrical control box by optimizing the heat dissipation path and increasing the heat dissipation area, ensuring the stable operation and long lifespan of the heat pump unit.

[0026] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] like Figures 1 to 6As shown, this embodiment provides an electrical control box with an integrated heat dissipation module, including: a mounting base 1, a cooling pipe 4, a cover plate 3, and a circuit board. The mounting base 1 has a groove 102, and the groove 102 has a first arc-shaped groove 1023 for mounting the cooling pipe 4. The cover plate 3 covers the groove 102 and is flush with the mounting surface 101 of the mounting base 1 for mounting the circuit board. The circuit board is mounted on the mounting surface 101 and is at least partially located above the cover plate 3.

[0030] Based on the above scheme, in terms of working principle, the electrical control box achieves efficient heat dissipation through a clever structural design. Specifically, the recess 102 on the mounting base 1 has a first arc-shaped groove 1023 specifically for installing the cooling pipe 4. The cooling pipe 4 is arranged along the arc-shaped groove, which can make full use of space and optimize the heat dissipation path. The cover plate 3 tightly covers the recess 102 and is flush with the mounting surface 101 of the mounting base 1, which protects the internal circuit board and ensures the clean appearance of the electrical control box. The circuit board is mounted on the mounting base 1 and partially covers the cover plate 3. This layout allows the heat generated by the circuit board to be quickly conducted and dissipated through the cooling pipe 4. During operation, the cooling medium (such as water or refrigerant) in the cooling pipe 4 circulates, continuously absorbing and carrying away the heat generated by the circuit board, thereby ensuring that the electrical control box can maintain a stable operating temperature under long-term, high-load operation.

[0031] In terms of beneficial effects, this technical solution has significant advantages over traditional heat pump unit frequency converter drive modules. Firstly, in terms of cost, the integrated heat dissipation design reduces the need for additional heat dissipation equipment and materials, thereby lowering the overall cost. Secondly, in terms of installation and replacement, the electrical control box has a more compact structure and is easier to maintain. The integrated design of the cooling pipe 4 and the mounting base 1 simplifies the installation process and reduces installation difficulty; at the same time, since the cover plate 3 is flush with the mounting base 1 and easy to disassemble, it makes it more convenient to replace the circuit board or perform maintenance operations during after-sales service. Furthermore, this technical solution significantly improves heat dissipation efficiency. The cooling pipe 4 is directly attached to the underside of the circuit board, achieving rapid heat conduction and dissipation, effectively preventing localized overheating. This not only extends the service life of the circuit board but also improves the overall stability and reliability of the electrical control box.

[0032] Furthermore, the groove 102 includes a first groove 1021 and second grooves 1022 located on both sides of the first groove 1021. The first groove 1021 is provided with the first arc-shaped groove 1023, and the vertical height of the second groove 1022 is higher than the vertical height of the first groove 1021. The groove 102 is jointly formed by the first groove 1021 and the second grooves 1022 located on both sides, forming a more complex structure, which aims to further optimize the installation and heat dissipation effect of the cooling pipe 4. The first groove 1021 is located in the center of the groove 102, and is provided with the first arc-shaped groove 1023, which is the key position for the installation of the cooling pipe 4. The cooling pipe 4 is arranged along the first arc-shaped groove 1023, which can fit tightly in the first groove 1021 to ensure effective heat conduction.

[0033] The second grooves 1022, located on either side of the first groove 1021, serve a stabilizing and supporting function. Of particular note is that the vertical height of the second grooves 1022 is designed to be higher than that of the first groove 1021. This design not only increases the complexity and depth of the grooves 102 but also enables specific functions. Specifically, this height of the second grooves 1022 is designed to cooperate with the cover plate 3 to achieve a locking function. When the cover plate 3 is placed on the groove 102, due to the height advantage of the second grooves 1022, they can fit tightly with the corresponding structures on the cover plate 3, forming an effective locking mechanism. This locking function not only enhances the stability of the cover plate 3, preventing it from loosening or falling off during operation, but also improves the overall structural strength of the electrical control box.

[0034] Furthermore, the cover plate 3 includes a plate body 301 and a protrusion 302 protruding from the bottom of the plate body 301. The protrusion 302 is positioned opposite to the first groove 1021, and the protrusion 302 has a second arc-shaped groove 303 that cooperates with the first arc-shaped groove 1023 to define the cooling pipe 4. The cover plate 3 is composed of two parts: the plate body 301 and the protrusion 302 protruding from the bottom of the plate body 301. This design cleverly matches the groove 102 structure of the electrical control box, and in particular, forms a close correspondence with the first groove 1021. The position of the protrusion 302 precisely corresponds to the first groove 1021. This layout not only ensures the stable installation of the cover plate 3, but also provides the possibility for the precise positioning of the cooling pipe 4.

[0035] Crucially, a second arc-shaped groove 303 is specially formed on the protrusion 302. This design detail perfectly complements the first arc-shaped groove 1023 on the first groove 1021, jointly defining the position of the cooling pipe 4. The cooling pipe 4 is cleverly sandwiched between the two, ensuring both installation stability and maximizing heat dissipation. Through the tight fit between the second arc-shaped groove 303 and the first arc-shaped groove 1023, the cooling pipe 4 is tightly fitted within the groove 102, allowing heat to be quickly and effectively conducted away, thereby improving the heat dissipation efficiency of the control box.

[0036] Furthermore, this design further enhances the overall structural strength of the electrical control box. The protrusion 302 of the cover plate 3 not only provides additional support, but also enhances the impact and vibration resistance of the entire electrical control box through the tight fit between the second arc groove 303 and the cooling pipe 4.

[0037] Meanwhile, the cover plate 3's plate body 301 is tightly fitted with the second groove 1022 via fasteners, achieving a stable locking effect. This design not only ensures the stability of the cover plate 3 after installation but also facilitates subsequent maintenance and replacement operations. Specifically, multiple first locking holes 1025 are carefully set on the second groove 1022. These holes are arranged in an orderly manner, providing accurate installation positions for the fasteners. Correspondingly, second locking holes 304, corresponding one-to-one with these first locking holes 1025, are also opened on the cover plate 3's plate body 301. When the fastener passes through the second locking hole 304 and is firmly fixed in the first locking hole 1025, a stable mechanical connection is formed between the cover plate 3 and the second groove 1022. The advantages of this locking mechanism lie in its stability and ease of maintenance. In terms of stability, through the setting of multiple locking points, the cover plate 3 is firmly fixed to the electrical control box, maintaining a stable installation state even under vibration or impact environments. In terms of ease of maintenance, when it is necessary to disassemble or replace the cover plate 3, the operation can be easily completed by simply loosening the fasteners, without complicated tools or steps.

[0038] Moreover, this design fully considers the overall aesthetics and compact structure of the control box. The fasteners and locking holes not only meet functional requirements but also minimize the impact on appearance, maintaining the cleanliness and uniformity of the control box.

[0039] In further optimizing the technical solution of this patent, special attention was paid to the structural strength and stability of the electrical control box. Therefore, reinforcing elements were incorporated into the design to enhance the overall load-bearing capacity of the electrical control box. Specifically, multiple first reinforcing elements 1024 are spaced apart between the first groove 1021 and the second grooves 1022 on both sides. These reinforcing elements not only enhance the connection strength between the first groove 1021 and the second grooves 1022, but also improve the overall structural stability of the groove 102. Like a bridge, they tightly connect the second grooves 1022 on both sides to the central first groove 1021, effectively resisting external vibrations and impacts, and ensuring the safe operation of the internal components of the electrical control box. Multiple second reinforcing elements 103 are also carefully arranged at the bottom of the mounting base 1. These reinforcing elements directly enhance the structural strength of the mounting base 1, providing stable support for the electrical control box.

[0040] Preferably, one end of the groove 102 along its length is provided with a clearance structure to allow the cooling pipe 4 to pass through. This innovative design solves the limitations of the cooling pipe 4 in installation and layout, providing a more flexible and smooth passage path for the cooling pipe 4. The clearance structure cleverly utilizes the space of the groove 102, reserving sufficient space for the cooling pipe 4 by appropriately reducing or adjusting the shape and size of the groove 102. In this way, when the cooling pipe 4 needs to pass through the groove 102, it is no longer obstructed and can be smoothly arranged along the preset path. This design not only improves the ease of installation of the cooling pipe 4, but also optimizes the internal layout of the electrical control box. It allows the cooling pipe 4 to fit more tightly under the circuit board, improving heat dissipation efficiency, while also reducing the overall size and weight of the electrical control box.

[0041] Meanwhile, the design of the air-sheltered structure also fully considers the maintenance and replacement needs of the electrical control box. When it is necessary to adjust or replace the cooling pipe 4, the operation can be carried out more easily by the staff without the need for large-scale disassembly and reassembly of the electrical control box, thereby reducing maintenance costs and time.

[0042] Optionally, the cooling pipe 4 can be connected to a cold water supply device or a refrigerant pipeline. This design allows the cooling pipe 4 to be flexibly configured according to actual application scenarios and heat dissipation requirements. When the control box requires stronger heat dissipation capabilities, the cooling pipe 4 can be connected to a cold water supply device to quickly dissipate heat from the control box using low-temperature cold water. When the control box is in a specific industrial environment or requires higher heat dissipation efficiency, the cooling pipe 4 can be connected to a refrigerant pipeline to achieve more efficient heat dissipation by utilizing the evaporative heat absorption effect of the refrigerant. This design not only enhances the heat dissipation capacity and adaptability of the control box but also improves its flexibility and reliability in different application scenarios. At the same time, it also provides users with more options, allowing them to customize and optimize the configuration according to their actual needs.
