[0046]

[0047] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0049] The main solution of this application embodiment is: by setting the control board in the box, and setting the power device in the control board, setting the refrigerant assembly in the box and attaching it to the power device, and then setting the air-cooling assembly and the refrigerant assembly together, and connecting the refrigerant assembly to the refrigerant of the air conditioner to cool the power device of the control board, and using the air-cooling assembly to assist the refrigerant assembly in cooling the power device of the control board.

[0050] Current air conditioners typically employ either air cooling or refrigerant loop cooling technologies to cool power devices and ensure stable operation. However, these traditional cooling technologies have limitations. For example, air cooling efficiency drops significantly at high ambient temperatures or when airflow is insufficient. While refrigerant loop cooling offers advantages over air cooling at high temperatures, its effectiveness is also limited at even higher temperatures.

[0051] This application provides a solution to improve the heat dissipation efficiency of the electrical control box of existing air conditioners.

[0052] It should be understood that the electrical control box assembly in this embodiment is applied to an air conditioner.

[0053] Among them, air conditioners can be central air conditioning systems, household air conditioners, ventilation systems, etc.

[0054] Reference Figures 1 to 3 In one embodiment of this application, the electrical control box assembly includes a box body 10, a control board 20, a refrigerant assembly 30, and an air-cooling assembly 40, wherein:

[0055] The control board 20 is located inside the housing 10, and the control board 20 is equipped with power devices;

[0056] The refrigerant assembly 30 is disposed inside the housing 10 and is attached to the power device. The refrigerant assembly 30 is used to connect the refrigerant of the air conditioner to cool the power device of the control board 20.

[0057] The air-cooled component 40 and the refrigerant component 30 are stacked together to assist the refrigerant component 30 in cooling the power devices of the control board 20.

[0058] In the electrical control box assembly, the power devices on the control board 20 are the main heat source, generating a large amount of heat during operation. If this heat is not dissipated in time, it may affect the performance of the control board 20 or even damage the equipment. Therefore, it is necessary to dissipate the heat in a timely manner to keep the power devices within a safe temperature threshold. To achieve this, a refrigerant assembly 30 is first used to attach the power devices and connect the refrigerant from the air conditioner. The heat generated by the power devices is absorbed during the circulation of the refrigerant, thereby dissipating heat from the power devices and achieving a cooling effect. In addition, a substrate for placing the refrigerant assembly 30 can be attached to the encapsulation surface of the power devices, and the pipes guiding the refrigerant flow can be placed on the substrate or a corresponding mounting groove can be provided on the substrate to embed the pipes guiding the refrigerant flow inside. Through the thermal conductivity of the substrate, heat can be better guided to the refrigerant for heat exchange, thereby achieving better heat dissipation.

[0059] To achieve better heat dissipation, an air-cooling component 40 can be installed on the side of the refrigerant component 30 away from the power devices. This assists the refrigerant component 30 in cooling the power devices on the control board 20 when its heat dissipation capacity is insufficient. This combines air cooling structure with refrigerant loop heat dissipation, improving the heat dissipation efficiency of the power devices. The air-cooling component 40 can achieve air cooling by incorporating a fan or by using the airflow generated by the fan in an air conditioner, resulting in a more efficient heat dissipation process. Furthermore, the fan or airflow channel of the air-cooling component 40 can be designed to be adjustable to adjust the airflow volume or direction according to the actual heat dissipation requirements of the power devices, thereby achieving more precise temperature control.

[0060] Under actual working conditions, by introducing a dual heat dissipation structure combining an environmental air duct and a refrigerant loop, the high-temperature temperature rise of power devices can be reduced by about 10°C, achieving strong cooling and solving the problem of cooling output and stable operation of air conditioning products in high-temperature environments and special high-temperature scenarios. It enables variable frequency control to achieve full-capacity cooling output at 58°C and cooling operation at 70°C, providing technical support for high-temperature cooling output and delivering better cooling performance.

[0061] The refrigerant assembly 30 can be made of a material with good thermal conductivity, such as copper or aluminum, and its surface is in close contact with the power device to improve heat exchange efficiency. On the other side of the refrigerant assembly 30, the air-cooling assembly 40 generates airflow through a fan, external negative pressure, or other ventilation device to remove heat from the surface of the refrigerant assembly 30, thereby reducing the temperature of the power device.

[0062] The refrigerant component 30 and the air-cooling component 40 are set to the same length to ensure that they can work together during the heat dissipation process to achieve the best heat dissipation effect.

[0063] Optionally, refer to Figure 4 Another embodiment of this application provides an electronic control box assembly, based on the above... Figures 1 to 3 In any of the embodiments shown, the refrigerant assembly 30 includes a first substrate 31 and a heat exchange tube 32, wherein:

[0064] One side of the first substrate 31 is attached to the power device to dissipate the heat from the power device; the heat exchange tube 32 is disposed inside the first substrate 31 and is used to connect the refrigerant of the air conditioner to exchange the heat dissipated by the first substrate 31.

[0065] In the refrigerant assembly 30, the heat exchange tube 32 can be easily connected to the refrigerant of the air conditioner, thereby effectively exchanging the heat generated by the power devices through the refrigerant. The heat exchange tube 32 can be made of a material with high thermal conductivity, such as copper tube, and the refrigerant flowing inside can be water or other suitable cooling media. By arranging the heat exchange tube 32 within the first substrate 31, the contact area with the first substrate 31 can be increased to maximize heat exchange efficiency and ensure that heat can be rapidly conducted from the power devices to the refrigerant. In addition, to optimize heat dissipation, the heat exchange tube 32 can adopt a multi-loop design, which increases the surface area of ​​contact between the refrigerant and the heat source, thereby improving the efficiency of heat exchange.

[0066] Optionally, refer to Figure 5 Another embodiment of this application provides an electronic control box assembly, based on the above... Figures 1 to 3 In any of the embodiments shown, the air-cooled assembly 40 has a heat dissipation duct 41 for communication with the air duct of the air conditioner.

[0067] In this embodiment, the heat dissipation duct 41 of the air-cooled component 40 is designed to be directly connected to the air duct of the air conditioner, thereby allowing the airflow from the air conditioner's fan to flow directly through the air-cooled component 40. This enables the air-cooled component 40 to perform heat exchange, thus facilitating the cooling of the power devices by the auxiliary refrigerant component 30. This design of the heat dissipation duct 41 not only improves heat dissipation efficiency but also reduces air resistance and increases airflow speed due to the direct connection of the duct, enhancing the heat dissipation effect. In practical applications, this design ensures that the temperature of the electrical control box component remains within a safe range under high-load operating conditions, thereby guaranteeing the stable operation of the entire air conditioner.

[0068] The air-cooling component 40 may include multiple fans, which can be axial fans or centrifugal fans, selected according to actual needs. The use of fans can enhance the airflow of the air-cooling component 40, making the airflow more rapid, thereby improving heat dissipation efficiency.

[0069] Among them, the air-cooled component 40 can achieve more efficient heat dissipation by introducing the airflow of the air conditioner's fan. The air-cooled component 40 can be a heat dissipation fin 43 or a heat dissipation fin. The airflow of the air conditioner's fan flows through the heat dissipation fin 43 or the heat dissipation fin, which can carry away the heat exchanged by the heat dissipation fin 43 or the heat dissipation fin. By increasing the contact area with the air through the heat dissipation fin 43 or the heat dissipation fin, the heat dissipation performance of the air-cooled component 40 can be greatly improved.

[0070] Furthermore, to improve the heat dissipation performance of the control box assembly, the air outlet 13 of the air-cooled component 40 is connected to the air duct of the air conditioner. When there is airflow in the air duct of the air conditioner, it creates negative pressure in the heat dissipation duct 41, thereby achieving a more efficient heat dissipation effect. This design utilizes aerodynamic principles; through the negative pressure effect of the air duct, more external air can be attracted into the heat dissipation duct 41 to enhance the heat dissipation effect. In the heat dissipation design of the control box assembly, the utilization of this negative pressure effect can significantly improve the heat dissipation capacity of power devices.

[0071] Optionally, refer to Figure 6 In another embodiment of this application, an electronic control box assembly is provided, based on the above... Figure 5 In the embodiment shown, the air-cooled assembly 40 includes a second substrate 42 and a plurality of heat dissipation fins 43, wherein:

[0072] The second substrate 42 is attached to the refrigerant assembly 30; a plurality of heat dissipation fins 43 are disposed on one side of the substrate, and adjacent heat dissipation fins 43 are spaced apart to define a heat dissipation channel 41.

[0073] In this embodiment, the close fit between the second substrate 42 and the refrigerant assembly 30 ensures that heat can be transferred from the power device to the second substrate 42 through the refrigerant assembly 30, and then dissipated through the heat dissipation fins 43. The spacing of the heat dissipation fins 43 not only ensures smooth airflow, but also effectively guides airflow through the defined heat dissipation channel 41, enhancing the heat dissipation effect. This design allows the air-cooled assembly 40 to more efficiently remove heat from the surface of the refrigerant assembly 30 during operation, reducing the temperature of the power device.

[0074] The heat dissipation fins 43 can be made of metallic materials, such as aluminum or copper, which have good thermal conductivity and can quickly conduct heat from the second substrate 42 to the fin surface, and then remove the heat through airflow. To improve heat dissipation efficiency, the heat dissipation fins 43 can be designed with specific shapes and angles to optimize airflow paths and increase heat exchange area. Furthermore, the layout and number of heat dissipation fins 43 can be adjusted according to actual heat dissipation requirements to achieve optimal heat dissipation performance.

[0075] In this embodiment, the heat dissipation fins 43 of the air-cooled component 40 and the refrigerant component 30 work together to form a highly efficient heat dissipation system. The refrigerant component 30 conducts heat exchange and removes the heat generated by the power device through the heat exchange tube 32. When the heat in the heat exchange tube 32 becomes too high, the heat is transferred to the second substrate 42, and then dissipated into the air through the heat dissipation air ducts 41 of the heat dissipation fins 43. This heat dissipation method, which combines a refrigerant ring and an air-cooled structure, can not only effectively reduce the temperature of the power device, but also maintain the stable operation of the air conditioner in high-temperature environments, ensuring the reliability and service life of the equipment.

[0076] Among them, such as Figure 4 and Figure 6 As shown, the second substrate 42 may have a half-groove for accommodating the heat exchange tube 32 in the refrigerant assembly 30. This half-groove mates with the half-groove of the first substrate 31 in the refrigerant assembly 30 to form a space for accommodating the heat exchange tube 32. The heat exchange tube 32 is positioned between the first substrate 31 and the second substrate 42, achieving a good fit between them and greatly improving heat exchange efficiency. This design not only ensures close contact between the heat exchange tube 32 and the substrate, but also reduces the thermal resistance between the heat exchange tube 32 and the substrate through the half-groove, thereby improving the overall heat conduction efficiency. Furthermore, the half-groove design provides additional mechanical support for the heat exchange tube 32, reducing stress caused by vibration or thermal expansion during operation, thus improving the stability and reliability of the entire electrical control box assembly.

[0077] Optionally, refer to Figure 7 This application also provides an embodiment of an electronic control box assembly, based on the above... Figures 1 to 3In any of the embodiments shown, the electrical control box assembly further includes a mounting bracket 50, wherein:

[0078] The mounting bracket 50 is snapped into the housing 10, and the air-cooled component 40 is detachably mounted on the mounting bracket 50. The air-cooled component 40 is fitted together with the refrigerant component 30.

[0079] In this embodiment, the design of the mounting bracket 50 makes the maintenance and replacement of the electrical control box assembly more convenient. Through a snap-fit ​​mechanism, the mounting bracket 50 can be securely fixed to the box 10, while allowing for quick disassembly and installation of the air-cooling component 40. This design not only facilitates routine maintenance but also makes it easy to replace or upgrade the air-cooling component 40 without requiring complex disassembly of the entire electrical control box assembly.

[0080] The mounting bracket 50 can be made of high-strength, corrosion-resistant materials to ensure stability and durability during long-term use. The bracket's structural design takes into account the size and shape of the air-cooling component 40, ensuring a tight fit between the air-cooling component 40 and the refrigerant component 30 after installation, thereby guaranteeing heat dissipation. Furthermore, the mounting bracket 50 may be equipped with locating pins or locating holes to ensure the accuracy and consistency of the air-cooling component 40 during installation, preventing a decrease in heat dissipation efficiency due to improper installation.

[0081] Optionally, refer to Figure 8 Another embodiment of this application provides an electronic control box assembly, based on the above... Figure 7 In the embodiment shown, the mounting bracket 50 includes a bracket body 51 and a bracket support arm 52, wherein:

[0082] The bracket body 51 is detachably connected to the air-cooling component 40; the bracket support arm 52 is provided on the bracket body 51, and the bracket support arm 52 is used to detachably connect the box 10 and support the air-cooling component 40 and the refrigerant component 30 stacked together.

[0083] In this embodiment, the detachable connection between the bracket body 51 and the air-cooling component 40 makes the maintenance and upgrade of the electrical control box assembly more flexible and convenient. The bracket support arm 52 not only provides additional support for the air-cooling component 40, ensuring its stability during operation, but also, through its detachable connection, makes the connection between the mounting bracket 50 and the box body 10 more robust and reliable. This design allows for quick replacement or maintenance of the air-cooling component 40 without disassembling the entire electrical control box assembly, greatly improving the maintenance efficiency and service life of the electrical control box assembly.

[0084] The bracket body 51 can be a rectangular frame structure with an inner diameter similar to that of the second substrate 42 of the air-cooling component 40, and its inner wall is provided with positioning grooves that match the second substrate 42 of the air-cooling component 40. This design not only ensures precise alignment between the bracket body 51 and the air-cooling component 40, but also allows for quick and easy installation of the air-cooling component 40 through the positioning grooves. After the air-cooling component 40 is engaged with the bracket body 51, it abuts against the refrigerant component 30 under the action of the bracket support arm 52, resulting in stronger connection stability. The structural design of the bracket support arm 52 ensures that the air-cooling component 40 can fit tightly against the refrigerant component 30 after installation, thereby guaranteeing heat dissipation.

[0085] In addition, the bracket body 51 may be provided with positioning pins or positioning holes to allow for fixed connection with the refrigerant assembly 30 or with the power devices on the control board 20 during installation, thus preventing a decrease in heat dissipation efficiency due to improper installation. The bracket body 51 and the bracket support arm 52 may be made of high-strength, corrosion-resistant materials to ensure stability and durability during long-term use.

[0086] Optionally, refer to Figure 9 and Figure 10 Another embodiment of this application provides an electronic control box assembly, based on the above... Figure 8 In the embodiment shown, the housing 10 is provided with a bracket mounting hole 11, which is detachably connected to the bracket support arm 52. The bracket mounting hole 11 is used to install the mounting bracket 50 so that the mounting bracket 50 supports the air-cooled component 40 and the refrigerant component 30 in close contact.

[0087] In this embodiment, the bracket mounting holes 11 provided on the housing 10 facilitate the installation of the mounting bracket 50. The detachable connection between the mounting holes 11 and the bracket support arm 52 ensures the stability of the connection between the mounting bracket 50 and the housing 10, while also facilitating the installation and removal of the air-cooling assembly 40. This design not only simplifies the assembly process of the electrical control box assembly but also allows for quick maintenance or replacement of the air-cooling assembly 40 without disassembling the entire electrical control box assembly, thereby improving maintenance efficiency and reducing maintenance costs.

[0088] In practical applications, the stability and reliability of the electrical control box assembly are crucial. The cooperation between the bracket mounting hole 11 and the bracket support arm 52 not only improves the structural stability of the electrical control box assembly but also reduces stress caused by vibration or thermal expansion by minimizing relative movement between components, thereby extending the service life of the electrical control box assembly. Furthermore, the design of the bracket mounting hole 11 can be combined with other auxiliary fixing devices, such as screws and clips, to further enhance the stability of the connection and ensure the stable operation of the electrical control box assembly in various working environments.

[0089] Optionally, refer to Figure 11 In another embodiment of this application, an electronic control box assembly is provided, based on the above... Figure 8 In the embodiment shown, the mounting bracket 50 includes a refrigerant pipe clip 53, wherein:

[0090] The refrigerant pipe clip 53 is located on the side of the bracket body 51 away from the bracket support arm 52, and the refrigerant pipe clip 53 is used for detachable connection of the refrigerant assembly 30.

[0091] In this embodiment, the design of the refrigerant pipe clip 53 greatly facilitates the installation and removal of the refrigerant assembly 30. The detachable connection between the refrigerant pipe clip 53 and the refrigerant assembly 30 ensures the stability and reliability of the refrigerant assembly 30 within the electrical control box assembly, while also facilitating quick maintenance or replacement when needed.

[0092] The refrigerant pipe clip 53 can be a ball-shaped pipe clip, which is used to conveniently fasten the refrigerant pipe, thereby fixing the refrigerant pipe and the mounting bracket 50. This allows for a better tight fit between the refrigerant pipe and the air-cooled component 40. The ball-shaped design of the refrigerant pipe clip 53 allows the refrigerant pipe to rotate freely within a certain range, which can adapt to the needs of different installation angles and positions, while reducing the problem of refrigerant flow obstruction caused by improper installation.

[0093] Furthermore, the refrigerant pipe clip 53 can be designed with a certain degree of elasticity. This allows the clip to provide appropriate tension when the refrigerant pipe undergoes thermal expansion or contraction, maintaining a tight connection between the refrigerant pipe and the clip and preventing loosening due to thermal expansion and contraction. This elastic design not only improves the reliability of the connection but also helps maintain the continuity and stability of refrigerant flow.

[0094] Optionally, refer to Figure 12 This application also provides an embodiment of an electronic control box assembly, based on the above... Figures 1 to 3 In any of the embodiments shown, a heat dissipation space 60 is provided between the air-cooled component 40 and the housing 10.

[0095] In this embodiment, the design of the heat dissipation space 60 allows air to flow freely between the air-cooling component 40 and the housing 10, which helps to quickly transfer the heat generated by the air-cooling component 40 to the outside of the housing 10, and also prevents heat from accumulating inside the electrical control box, thereby reducing the temperature of the entire electrical control box assembly.

[0096] In addition, the heat dissipation space 60 provides a certain distance between the air-cooling component 40 and the housing 10. This distance can reduce the impact of heat conduction on the housing 10 and avoid heat backflow caused by direct contact, thereby improving heat dissipation efficiency.

[0097] In practical applications, the design of the heat dissipation space 60 can also take into account environmental factors, such as airflow speed and ambient temperature, to ensure good heat dissipation performance under various operating conditions. Furthermore, the design of the heat dissipation space 60 can be combined with other heat dissipation technologies, such as heat pipes and heat plates, to achieve a more efficient heat dissipation solution and improve the heat dissipation performance of the electrical control box components.

[0098] Optionally, refer to Figure 13 Another embodiment of this application provides an electronic control box assembly, based on the above... Figure 5 In the embodiment shown, the box body 10 has a first air inlet 12 and an air outlet 13 on opposite sides, and the heat dissipation duct 41 extends along the direction from the first air inlet 12 to the air outlet 13.

[0099] In this embodiment, the layout design of the heat dissipation duct 41 extending along the direction from the first air inlet 12 to the air outlet 13 effectively guides external airflow through the air-cooled assembly 40, thereby carrying away the heat generated by the power devices. The arrangement of the first air inlet 12 and the air outlet 13 ensures smooth airflow, enabling the electrical control box assembly to continuously dissipate heat during operation. This design not only improves heat dissipation efficiency but also reduces wind resistance and increases airflow speed due to the optimized airflow path, thus enhancing the heat dissipation effect.

[0100] This application also proposes an air conditioner that includes an electrical control box assembly as described in the above embodiments.

[0101] It is worth noting that since the air conditioner of this application is based on the above-mentioned electrical control box assembly, the embodiments of the air conditioner of this application include all the technical solutions of all embodiments of the above-mentioned electrical control box assembly, and the technical effects achieved are exactly the same, so they will not be repeated here.
