[0047] The following will describe the heat dissipation device of the embodiments of the present invention in conjunction with Figures 1-6 Describe the heat dissipation device of the embodiments of the present invention.

[0048] In conjunction with Figure 1 , the heat dissipation device of the embodiments of the present invention is applicable to the electric control box 200 of the outdoor unit 100 of the air conditioner. Specifically, the electric control box 200 is arranged in the chassis 101 of the outdoor unit 100 of the air conditioner, and it includes a box body and electrical components such as a circuit board arranged in the box body. The box body is fixedly connected to the chassis 101 of the outdoor unit 100 of the air conditioner. When the air conditioner operates, the electrical components in the box body of the electric control box 200 generate heat. If the heat cannot be dissipated in time, the internal electrical components may be damaged due to excessive temperature, affecting the use safety and service life. The heat dissipation device of the embodiments of the present invention can achieve the heat dissipation of the electric control box 200 and play a protective role for the electrical components in the electric control box 200.

[0049] The heat dissipation device of the embodiments of the present invention includes a first flow channel 202, a liquid storage tank 300, and a driving pump 500. The first flow channel 202 is located in the box body of the electric control box 200. The liquid storage tank 300 is located in the chassis 101 of the outdoor unit 100 of the air conditioner, and is provided with a first outlet 302 and a first inlet 303. The first outlet 302 is communicated with the inlet of the first flow channel 202 through a circulation pipeline 600, and the first inlet 303 is communicated with the outlet of the first flow channel 202 through the circulation pipeline 600. The driving pump 500 is connected to the circulation pipeline 600 and is used to drive the heat exchange medium to circulate between the first flow channel 202 and the liquid storage tank 300.

[0050] It should be noted that in this embodiment, the above heat exchange medium is usually a liquid such as a liquid refrigerant or water, or can also be a gaseous heat transfer medium with good heat transfer effect.

[0051] In conjunction with Figure 2 and Figure 3, in this embodiment, the box body includes a top plate, a bottom plate, and a surrounding plate connected between the top plate and the bottom plate. The first flow channel 202 is provided on at least one of the top plate, the bottom plate, and the surrounding plate. Optionally, the surrounding plate is fixedly connected to the chassis 101, and the side of the surrounding plate in contact with the chassis 101 is the back panel 201 of the box body, and the first flow channel 202 is provided on the back panel 201.

[0052] In this embodiment, there is no particular limitation on the specific geometric shape of the first flow channel 202. It can be flexibly designed into various shapes such as square, circular, oval, etc., as long as it can satisfy the effective flow of the fluid therein. Such design flexibility helps to adapt to different engineering requirements and optimize the heat exchange efficiency.

[0053] At the same time, there are also various choices for the extension path of the first flow channel 202. For example, it can be designed into a complex path such as an S shape or a spiral shape. Such a design strategy can effectively increase the flow distance of the fluid in the flow channel, enabling the fluid to have more sufficient time and space for heat exchange with the heat exchange medium, thus significantly enhancing the overall heat exchange effect.

[0054] In addition, by designing the first flow channel 202 into a non-linear and evenly distributed form, it can ensure more balanced heat exchange at each position of the back panel 201, avoiding the phenomenon of local overheating or overcooling, which is of great significance for maintaining the stable operation of the equipment and extending its service life.

[0055] The heat dissipation device provided by the present invention utilizes the box body design of the electric control box 200 to form the first flow channel 202 structure, enabling the box body that was originally only used as an equipment accommodation space to have the function of conducting and dissipating heat, thus greatly saving the space required for additional heat dissipation facilities. Through this optimized design, there is no need to add complex heat dissipation components such as fans on the electric control box 200, significantly reducing the complexity of the overall structure and the maintenance difficulty, and making it more convenient for daily disassembly, installation, and maintenance operations.

[0056] In addition, the present invention also cleverly combines the characteristics of the chassis 101 of the air conditioner outdoor unit ￥100, uses it as the liquid storage tank 300, and makes full use of the advantage of the large-area contact between the chassis 101 of the air conditioner outdoor unit 100 and the external environment to achieve efficient natural convection heat dissipation. Such a design can not only effectively improve the heat dissipation efficiency, but also avoid the cost and energy consumption problems brought by additional heat dissipation equipment, reflecting the green and environmental protection design concept. Generally speaking, the heat dissipation device provided by the present invention simplifies the system structure and improves the heat dissipation performance, and has extremely high practical value and promotional significance.

[0057] Combined with Figure 2 , in an embodiment of the present invention, the heat dissipation device further includes a heat conducting member, which is disposed in the electric control box 200 and is used to conduct the heat generated by the operation of the electrical components in the electric control box 200 to the box body.

[0058] The heat-conducting component can quickly capture and concentrate the heat generated during the operation of the electrical components in the electrical control box 200, ensuring that this heat can effectively migrate from the heat source to the box structure. The heat-conducting component may be made of high-efficiency heat-conducting materials, such as high-heat-conducting metals like copper and aluminum, or composite materials with good heat-conducting capabilities, and is optimized in design to adapt to the complex environment and spatial layout within the electrical control box 200. The heat-conducting component is closely attached to the heat-generating components by means of contact or wrapping to form an efficient heat transfer path. When the heat is quickly transmitted to the box body of the electrical control box 200 via the heat-conducting component, it can further be dispersed and transmitted to the liquid storage tank 300 in the chassis 101 of the outdoor unit 100 of the air conditioner through the heat exchange medium passing through the first flow channel 202, and heat absorption and emission are carried out using heat exchange media such as water to achieve a large-range convective heat dissipation effect.

[0059] The design of this heat dissipation device integrated with the heat-conducting component significantly improves the heat management efficiency, reduces the risk of electrical components malfunctioning due to overheating, and simultaneously reduces the dependence on external heat dissipation devices. Due to its compact structure and the absence of additional auxiliary heat dissipation facilities such as fans, it effectively saves space occupancy, reduces noise pollution, and simplifies the equipment maintenance procedure. In addition, leveraging the large-area heat dissipation advantage of the chassis 101 of the outdoor unit 100 of the air conditioner, the heat dissipation performance of the entire system is greatly enhanced, strengthening the stability and service life of the electrical control equipment.

[0060] In an embodiment of the present invention, the heat-conducting component includes at least one metal heat-conducting plate 203, and the metal heat-conducting plate 203 is in contact and cooperation with the box body.

[0061] The metal heat-conducting plate 203 can be in close contact and cooperation with the box body of the electrical control box 200, thereby forming an efficient heat transfer channel. This design aims to ensure that the heat generated during the operation of the electrical components can quickly be transmitted to the box body through the heat-conducting plate, achieving effective heat dissipation from the inside to the outside.

[0062] In order to improve the heat-conducting efficiency and adapt to the layout of heat-generating components at different positions, the metal heat-conducting plate 203 can be customized into a bent S-shaped structure, which not only helps to increase the contact area with the heat-generating electrical components but also ensures good heat conduction contact with different parts of the box body, effectively covering and managing the heat distribution inside the entire electrical control box 200.

[0063] Between the metal heat-conducting plate 203 and the box body, mechanical connection means such as bolting and riveting can be used to enhance the contact force and stability between the two, ensuring that during the operation of the equipment, even in the face of conditions such as vibration or shock, the heat-conducting performance can remain stable and reliable.

[0064] The metal heat-conducting plate 203, with its specific shape and connection method, significantly improves the heat dissipation system's effectiveness. On the one hand, the S-shaped structure allows the heat-conducting plate to more fully absorb and dissipate heat from the electrical components, reducing the risk of hotspot accumulation. On the other hand, the stable connection technology ensures the continuity and effectiveness of the heat transfer process, thereby helping to extend the service life of the electrical components within the electrical control box 200, reduce failure rates, and enhance the overall system's operational stability and efficiency. Furthermore, by optimizing the heat dissipation path, the device reduces the need for additional heat dissipation components, simplifying the system structure and reducing costs and maintenance.

[0065] Combine Figure 1 and Figure 4 In one embodiment of the present invention, the liquid storage tank 300 is mounted on the chassis 102 of the air conditioner outdoor unit 100. Using the chassis 102 of the air conditioner outdoor unit 100 to dissipate heat does not affect the installation of other equipment and reduces space usage. The storage of heat exchange medium within the liquid storage tank stabilizes the unit, absorbs vibration, and reduces noise. Optionally, the liquid storage tank 300 is integrally formed with the chassis 102.

[0066] The liquid storage tank 300 is designed and integrated into the chassis 102 structure of the air-conditioning outdoor unit 100, so that the liquid storage tank 300 can fully utilize the characteristics of the large contact area between the chassis 102 of the air-conditioning outdoor unit 100 and the external environment and the good heat dissipation effect, thereby achieving efficient heat dissipation without occupying additional space resources and without having any impact on the installation of other supporting equipment.

[0067] The heat exchange medium stored in the liquid tank 300 not only meets the requirements of the air conditioning system's refrigeration cycle but also provides multiple optimization benefits. First, the integrated design of the liquid tank 300 and chassis 102 enhances the stability of the entire air conditioning outdoor unit 100, reducing vibration transmission during operation. Second, the liquid medium exhibits excellent acoustic damping properties, effectively absorbing and reducing noise generated by mechanical movement, contributing to the quiet performance of the air conditioning system. Furthermore, the liquid tank 300 may be manufactured using an integrated molding process, ensuring structural strength and sealing, preventing heat exchange medium leakage, and simplifying the production and assembly process.

[0068] This embodiment integrates the liquid storage function with the heat dissipation function of the chassis 102, ensuring the normal operation of the air conditioning system while maximizing space utilization and optimizing multi-dimensional functions. By stabilizing the chassis, reducing vibration, and lowering noise, the user experience and overall durability of the air conditioning system are significantly improved, demonstrating the advanced structural innovation and technological application of this invention.

[0069] Combine Figure 4 and Figure 5 ( Figure 5The arrow in the figure indicates the flow direction of the heat exchange medium). In an embodiment of the present invention, a partition 400 is provided in the liquid storage tank 300. The partition 400 divides the inside of the liquid storage tank 300 to form a second flow channel 301. One end of the second flow channel 301 is connected to the first outlet 302, and the other end of the second flow channel 301 is connected to the first inlet 303.

[0070] Inside the liquid storage tank 300, the partition 400 divides the inside of the liquid storage tank 300 into multiple interconnected second flow channels 301, forming a flow path similar to a maze. The first outlet 302 is connected to one end of the second flow channel 301, and the first inlet 303 is located at the other end, so that the heat exchange medium can enter from the first inlet 303 and be discharged from the first outlet 302 after passing through an extended and tortuous flow channel.

[0071] The partition 400 inside the liquid storage tank 300 is designed to be vertically arranged. One side is tightly connected to the top wall of the liquid storage tank 300, and the other side is also tightly connected to the bottom wall. In this way, the inner cavity of the liquid storage tank 300 is divided into multiple parallel and spaced flow channels, and these flow channels are connected in sequence to jointly form an extensible second flow channel 301 system. The benefits of this unique design are twofold: on the one hand, it increases the travel distance of the heat exchange medium inside the liquid storage tank 300, which is beneficial to improving the heat exchange efficiency and enhancing the heat dissipation performance of the entire system; on the other hand, it ensures that the heat exchange medium in each area inside the liquid storage tank 300 can flow continuously, effectively preventing the heat exchange medium from stagnating in local areas, resulting in uneven heat dissipation or reducing the heat conduction effect.

[0072] This embodiment not only makes full use of the internal space of the liquid storage tank 300, but also significantly improves the working efficiency of the entire heat dissipation device. Through the complex flow channel structure formed by adding the partition 400, the heat exchange medium can be in contact with the surface of the liquid storage tank 300 for a longer time and conduct heat exchange, improving the heat exchange efficiency and the stability of the equipment operation. At the same time, it avoids the local overheating problem caused by the stagnation of the heat exchange medium, ensuring the balanced heat dissipation and durability of the entire air conditioning system.

[0073] Optionally, the partition 400 includes a first plate body 401, a second plate body 402, and a third plate body 403. One end of the first plate body 401 is connected to one side of the liquid storage tank 300, and the other end is connected to the side wall of the second plate body 402. The second plate body 402 has a square structure. The third plate body 403 surrounds the outside of the second plate body 402. One end of the third plate body 403 is connected to the first plate body 401, and there is a gap between the other end and the first plate body 401. Thus, the inner cavity of the liquid storage tank 300 is divided into an approximate loop structure, increasing the extension path of the second flow channel 301 and ensuring the structural strength of the chassis 102 inside the liquid storage tank 300.

[0074] Combined with Figure 6, in an embodiment of the present invention, the heat dissipation device further includes a radiator 700, which is in contact and cooperation with the liquid storage tank 300 and is located outside the air conditioner outdoor unit 100.

[0075] The radiator 700 is closely combined with the liquid storage tank 300 and works in cooperation. It is specifically arranged in the external area of the air conditioner outdoor unit 100 body. Such a design arrangement aims to utilize the heat exchange medium flowing through the liquid storage tank 300 to absorb the heat generated by the electric control equipment or the air conditioning system, and transfer this heat to the external environment by means of contact and cooperation with the radiator 700. As a key component of the heat exchange medium, the structure and position design of the radiator 700 are crucial. It can usually be set as a fin structure, made of high-efficiency heat transfer materials such as aluminum alloy, having a large surface area and good heat conduction performance, and can quickly absorb heat from the high-temperature heat exchange medium in the liquid storage tank 300 in contact with it. When the air conditioning system operates, the heat exchange medium circulates in the second flow channel 301. After absorbing the internal heat in the liquid storage tank 300, it is then released to the surrounding air through the radiator 700. Since the radiator 700 is arranged outside the air conditioner outdoor unit 100, it can directly use natural convection or forced air cooling for heat dissipation, greatly improving the heat dissipation efficiency and system stability. Without increasing the additional space occupation, the heat dissipation efficiency of the entire air conditioning system is effectively improved. The close cooperation between the radiator 700 and the liquid storage tank 300 ensures that heat can be transferred from the system interior to the external environment in a timely and effective manner, reducing the working temperature of core components such as electrical components and compressors, thereby extending the equipment life, ensuring the high-performance stable operation of the air conditioning system, and reducing energy consumption and noise generation.

[0076] In some embodiments of the present invention, the circulation pipeline 600 is a heat-insulating pipe, such as a glass fiber pipe, a rubber and plastic foaming material pipe, etc. Thus, the heat exchange at the position of the circulation pipeline 600 can be reduced.

[0077] In an embodiment of the present invention, the heat dissipation device further includes:

[0078] A temperature detection device for detecting the temperature inside the electric control box 200 and inside the liquid storage tank 300;

[0079] A controller, which is respectively connected to the temperature detection device and the driving pump 500, and is used to control the operation of the driving pump 500 according to the detection signal of the temperature detection device.

[0080] The temperature detection device may include multiple temperature sensors, which are respectively deployed in the key heat - generating areas of the electric control box 200 and inside the liquid storage tank 300, and can accurately and continuously capture temperature data and feedback it to the controller in real - time. The controller, based on the preset temperature threshold and control logic, receives and analyzes these temperature signals. When it detects that the temperature inside the electric control box 200 or the temperature inside the liquid storage tank 300 reaches the set condition, it automatically issues an instruction to control the working state of the driving pump 500 (such as starting, accelerating, decelerating or stopping, etc.), thereby adjusting the flow rate and flow velocity of the heat - exchange medium in the second flow channel 301, and achieving effective regulation and closed - loop control of the system temperature.

[0081] Through such an intelligent design, the heat dissipation device of the present invention can not only respond in a timely manner to the changes in the heat load of the electrical control equipment, prevent equipment damage and performance degradation caused by overheating, but also ensure that the heat - exchange medium inside the liquid storage tank 300 always maintains an appropriate temperature range, improving the efficiency and stability of the entire heat - dissipation system. At the same time, due to the realization of automatic control, the need for manual intervention is greatly reduced, enhancing the reliability and service life of the system.

[0082] An embodiment of the present invention also provides an air conditioner, which includes an outdoor unit 100 of the air conditioner. The outdoor unit 100 of the air conditioner includes an electric control box 200 and also includes the heat - dissipation device described above.

[0083] By integrating the heat - dissipation device into the design of the traditional outdoor unit 100 of the air conditioner, the air conditioner of this embodiment not only improves the safety and stability of the equipment operation, effectively extends the service life of the electrical components, but also optimizes the energy - efficiency ratio of the entire system, reduces noise, and thus provides a more efficient, reliable and energy - saving air - conditioner solution for users.

[0084] The air conditioner in this embodiment may also include other structures such as a refrigeration system (including a compressor, a condenser, an evaporator, etc.), an air - duct system (including a fan, a blower and an air duct), and an electrical control system (including components such as a power module, a thermostat, a relay, a capacitor, a controller, etc.), which are not enumerated one by one here.

[0085] The heat - dissipation control method provided by the present invention will be described below. The heat - dissipation control method described below can be mutually referred to with the heat - dissipation device described above.

[0086] The heat - dissipation control method of the embodiment of the present invention is applied to the above - mentioned heat - dissipation device, and it includes the following steps:

[0087] S100. Obtain the first temperature inside the electric control box 200 and the second temperature inside the liquid storage tank 300. The first temperature inside the electric control box 200 and the second temperature inside the liquid storage tank 300 can be obtained by real - time detection by the temperature detection device. Moreover, both the first temperature and the second temperature can be obtained by taking the maximum value or the average value through multi - point measurement.

[0088] S200. Control the operation of the driving pump 500 based on the first temperature and the second temperature. Specifically, the controller receives and analyzes the first temperature and the second temperature based on a preset temperature threshold and control logic. When the first temperature and the second temperature meet the set conditions, an instruction is automatically issued to control the working state of the driving pump 500 (such as starting, accelerating, decelerating, or stopping, etc.), thereby adjusting the flow rate and flow of the heat exchange medium in the second flow channel 301 to achieve effective regulation and closed-loop control of the system temperature.

[0089] In some embodiments of the present invention, the operation of controlling the driving pump 500 based on the first temperature and the second temperature in step S200 specifically includes:

[0090] S201. Based on the first temperature being greater than or equal to the second temperature and the first temperature being greater than or equal to the preset temperature, control the driving pump 500 to start and control the flow rate of the driving pump 500 based on the first temperature;

[0091] S202. Based on the first temperature being less than the second temperature or the first temperature being less than the preset temperature, control the driving pump 500 to close.

[0092] It can be understood that the preset temperature is the highest temperature for the safe operation of the electric control box 200. When the first temperature is less than the preset temperature, no heat dissipation treatment is required. When the first temperature is greater than or equal to the preset temperature, heat dissipation is required.

[0093] When the first temperature is greater than the second temperature, it indicates that the temperature inside the electric control box 200 is higher than the temperature of the liquid storage tank 300. A good heat dissipation effect can be achieved by starting the driving pump 500 for heat exchange circulation; when the first temperature is equal to the second temperature, it indicates that the temperatures inside the electric control box 200 and the liquid storage tank 300 are equal. However, since the liquid storage tank 300 has better heat dissipation capacity, heat dissipation of the electric control box 200 can still be achieved; when the first temperature is less than the second temperature, starting the driving pump 500 will carry the temperature inside the liquid storage tank 300 to the electric control box 200, which is not conducive to heat dissipation of the electric control box 200. Therefore, the driving pump 500 is controlled to close, and the heat inside the electric control box 200 can be dissipated by means of heat conduction and the fan of the outdoor unit 100 of the air conditioner.

[0094] In this embodiment, by comparing the temperatures inside the electric control box 200 and the liquid storage tank 300, flexible adjustment can be made according to different situations, further improving the heat dissipation capacity and use safety.

[0095] In some embodiments of the present invention, the heat dissipation control method further includes:

[0096] S300. Generate an alarm control signal based on the first temperature and the second temperature. The controller is connected to the alarm device and generates an alarm control signal based on the first temperature being less than the second temperature and the first temperature being greater than or equal to the preset temperature, and controls the alarm device to send an alarm message. The alarm message includes, but is not limited to, a sound alarm message, a light prompt message, an image display prompt message, etc.

[0097] In some embodiments of the present invention, the heat dissipation control method further includes:

[0098] S400. Generate an air conditioner control signal based on the first temperature and the second temperature.

[0099] Specifically, the controller is connected to the electrical control system of the air conditioner and generates an air conditioner control signal based on the first temperature being less than the second temperature or the first temperature being less than the preset temperature, the first temperature being greater than or equal to the preset temperature, and lasting for a preset time. The air conditioner control signal includes a control signal for increasing the fan speed of the outdoor unit 100 of the air conditioner and a control signal for reducing the refrigeration power of the air conditioner. This can avoid damage to the internal electrical components due to overheating of the temperature of the electrical control box 200.
