[0038] In related technologies, as electronic control systems move toward integration, the integrated design of inverters and DC reactors has significantly reduced control cabinet size and reduced costs. However, integration also presents heat dissipation challenges, particularly in systems with high heat output. Rising temperatures inside the control cabinet can easily cause overheating of the inverter and reactor, impacting equipment performance and lifespan. Therefore, effectively addressing heat dissipation while maintaining the advantages of integration has become a key technical challenge that needs to be addressed in current electronic control system design.

[0039] Reference below Figure 1-Figure 5 An electric control cabinet assembly 1 according to an embodiment of the present invention is described.

[0040] like Figure 1-Figure 5 As shown, the electric control cabinet assembly 1 according to the present invention is used for an air compressor. The electric control cabinet assembly 1 includes a cabinet body 11, and a first installation space 111 and a second installation space 112 separated from each other are formed in the cabinet body 11, which helps to reduce mutual interference between different components, improve the stability and reliability of the overall system, and facilitate thermal management and maintenance.

[0041] The electrical control cabinet assembly 1 also includes a controller assembly, which is disposed within the first mounting space 111. The controller assembly is responsible for controlling and regulating the operation of the air compressor. Placing the controller assembly within the independent first mounting space 111 helps reduce external interference with its operation, ensuring control accuracy and stability.

[0042] The electrical control cabinet assembly 1 also includes an inverter 12, which is located within the second installation space 112 and spaced apart from the controller assembly. The inverter 12 is responsible for regulating the motor speed to optimize energy efficiency and load matching. Because the inverter 12 generates significant heat during operation, its separation from the controller assembly and placement within the independent second installation space 112 effectively reduces the potential impact of heat on the controller assembly. The inverter 12 and the controller assembly are electrically connected to enable data transmission and control signal exchange, ensuring effective communication between the inverter 12 and the controller assembly while reducing heat transfer between them.

[0043] The electrical control cabinet assembly 1 also includes a heat sink disposed within the second installation space 112 and adapted to dissipate heat from the inverter 12. The heat sink promptly dissipates heat generated by the inverter 12, maintaining the temperature within the second installation space 112 within a reasonable range, thereby ensuring normal operation of the inverter 12 and extending its service life.

[0044] Therefore, according to the electric control cabinet assembly 1 of the present invention, through reasonable space division, device layout and setting of heat dissipation device, the heat dissipation problem existing in the integrated electric control system is effectively alleviated, providing a strong guarantee for the efficient and stable operation of the air compressor.

[0045] According to some embodiments of the present invention, Figure 1 ,like Figure 3-Figure 5 As shown, the heat dissipation device includes a first heat dissipation device, which is arranged in the second installation space 112. The first heat dissipation device is formed with a heat dissipation surface for contacting the inverter 12. The heat dissipation surface can be in close contact with the inverter 12 so as to effectively absorb the heat generated by the inverter 12 during operation. A first heat exchange channel suitable for circulating a cooling medium is formed in the first heat dissipation device. When the cooling medium flows through the first heat exchange channel, the cooling medium will exchange heat with the heat inside the first heat dissipation device, thereby taking away the heat and achieving a heat dissipation effect. In this way, the heat generated by the inverter 12 can be effectively dissipated through the first heat dissipation device, keeping the temperature in the second installation space 112 within a reasonable range, ensuring the normal operation of the inverter 12 and extending its service life.

[0046] The heat dissipation device also includes a second heat dissipation device, which is disposed within the second installation space 112 and is adapted to facilitate airflow within the second installation space 112. This optimization of the heat dissipation effect by facilitating airflow within the second installation space 112 utilizes the basic principle of air convection, i.e., when air flows, it removes heat from the area it passes through, thereby reducing the temperature of that area.

[0047] According to some embodiments of the present invention, Figure 1 As shown, the cabinet 11 includes a cabinet body, which is the basic structure of the cabinet 11 and can provide sufficient strength and protect internal components from the influence of the external environment. A storage space is formed in the cabinet body, which is used to install and accommodate various devices and components in the electric control cabinet assembly 1.

[0048] The cabinet 11 also includes a partition 113, which is arranged inside the cabinet body and divides the accommodating space into a first installation space 111 and a second installation space 112, helping to reduce mutual interference between different components and improve the stability and reliability of the overall system. A connecting hole is formed on the partition 113 to connect the first installation space 111 with the second installation space 112. The presence of the connecting hole enables the first installation space 111 and the second installation space 112 to maintain communication or connection to a certain extent, allowing certain necessary cables to pass through the partition 113 to transmit data and signals between the first installation space 111 and the second installation space 112. At the same time, the connecting hole can also promote air flow between the first installation space 111 and the second installation space 112 to a certain extent, which helps with heat dissipation and temperature management.

[0049] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the electrical control cabinet assembly 1 also includes a reactor 13, a critical component in the electrical system used to limit the rate of current change and reduce grid fluctuations. Reactor 13 is located in the second installation space 112 and is isolated from the inverter 12. This helps reduce electromagnetic interference and heat transfer between reactor 13 and the inverter 12, thereby improving the stability and reliability of the overall system.

[0050] The electrical control cabinet assembly 1 further includes a third heat sink disposed in the second installation space 112 and configured to dissipate heat from the reactor 13. The third heat sink can effectively conduct or radiate heat generated by the reactor 13 into the air, thereby maintaining the operating temperature of the reactor 13 within a reasonable range.

[0051] According to some embodiments of the present invention, Figure 3 As shown, cabinet body 11 is formed with a first air inlet 114 and a first air outlet 115 that communicate with second installation space 112. The presence of first air inlet 114 and first air outlet 115 allows external cold air to enter second installation space 112 while simultaneously allowing internal hot air to be exhausted, creating effective air convection and thereby helping to reduce the temperature within the space. The third heat dissipation device is configured as a heat dissipation fan, which is disposed between first air inlet 114 and first air outlet 115.

[0052] According to some embodiments of the present invention, the reactor 13 is disposed opposite at least a portion of the first air inlet 114. When external cold air enters the second installation space 112 through the first air inlet 114, the cold air blows directly toward the reactor 13, removing heat from the surface of the reactor 13 and its surroundings.

[0053] According to some embodiments of the present invention, the reactor 13 is disposed opposite at least a portion of the first air outlet 115. When the internal hot air is discharged through the first air outlet 115, it further removes the heat generated by the reactor 13, ensuring that the reactor 13 can be fully cooled.

[0054] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the inverter 12 is arranged in the upper part of the second installation space 112, and the reactor 13 is arranged in the lower part of the second installation space 112. The inverter 12 will generate a certain amount of heat during operation, while the reactor 13 generates relatively less heat. The side wall of the cabinet 11 is formed with a second air outlet 116 that is directly opposite to the second heat dissipation device. After the external cold air enters the second installation space 112 to cool the inverter 12, it can be discharged from the second air outlet 116 to improve the heat dissipation efficiency. The bottom wall of the cabinet 11 is formed with a first air inlet 114 and a first air outlet 115. Cold air is introduced through the first air inlet 114 of the bottom wall. The cold air takes away the heat during the flow inside the equipment and is finally discharged through the first air outlet 115, forming an effective heat convection cycle. By arranging the inverter 12 and the reactor 13 at the upper and lower parts of the cabinet 11 respectively, and combining the specific first air inlet 114 and the first air outlet 115, effective heat dissipation of the internal components of the equipment is achieved, thereby ensuring long-term stable operation of the equipment.

[0055] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the bottom wall of the cabinet 11 is further formed with a second air inlet 117 that communicates with the first installation space 111. Located on the bottom wall of the cabinet 11, the second air inlet 117 allows cool air, which is relatively cool outside, to enter the first installation space 111 through the second air inlet 117. As the cool air flows in, it mixes with the hot air in the first installation space 111, and due to the temperature difference, convection currents are generated. This not only helps lower the overall temperature within the installation space, but also promotes even heat distribution, preventing local overheating.

[0056] According to some embodiments of the present invention, the electrical control cabinet assembly 1 further includes a first dustproof net, a second dustproof net, and a third dustproof net, wherein the first dustproof net is arranged at the first air inlet 114. Since the external environment may contain pollutants such as dust and impurities, the first dustproof net is used to prevent pollutants from entering the second installation space 112 through the first air inlet 114, thereby protecting the internal electrical components from contamination and damage. The second dustproof net is arranged at the second air outlet 116, and the second dustproof net is used to prevent pollutants from entering the second installation space 112 through the second air outlet 116, thereby ensuring the cleanliness and normal operation of the electrical components. The third dustproof net is arranged at the second air inlet 117, and the third dustproof net is used to prevent pollutants from entering the first installation space 111 through the second air inlet 117, thereby preventing pollutants from contaminating and damaging the internal components.

[0057] According to some embodiments of the present invention, Figure 2 As shown, first installation space 111 is provided with first and second isolated wire ducts 141, 142. First and second wire ducts 141, 142 are respectively used to accommodate and manage wire harnesses of different voltage levels or functions, thereby reducing mutual interference between high-voltage and low-voltage wire harnesses and improving signal purity and system stability.

[0058] The controller assembly includes a controller 15, which is responsible for receiving input signals, processing information, and issuing control commands to drive various components of the device. Controller 15 is located in the first mounting space 111 and has high-voltage and low-voltage interfaces for connecting electrical components of different voltage levels. The high-voltage interface is typically used to connect components that require high voltage power, while the low-voltage interface is used to connect components that require lower voltage power.

[0059] The controller assembly also includes a first electrical component 161 and a second electrical component 162. The first electrical component 161 is located in the first mounting space 111 and connected to the high-voltage interface via a high-voltage wiring harness. The second electrical component 162 is located in the first mounting space 111 and connected to the low-voltage interface via a low-voltage wiring harness. The high-voltage wiring harness and the low-voltage wiring harness are housed in the first wiring trough 141 and the second wiring trough 142, respectively. By separating the high-voltage and low-voltage wiring harnesses, the safety and reliability of the device are improved, ensuring that wiring harnesses of different voltage levels do not come into contact with each other.

[0060] The air compressor according to the present utility model is briefly described below.

[0061] According to the utility model, the air compressor includes a casing, a heat exchange circuit and an electric control cabinet assembly 1, and the heat exchange circuit is arranged in the casing; the electric control cabinet assembly 1 is constructed as the electric control cabinet assembly 1 in any one of the above embodiments, and the cabinet body 11 of the electric control cabinet assembly 1 is connected to the casing. The heat dissipation device of the electric control cabinet assembly 1 includes a water-cooled heat dissipation device for dissipating heat from the frequency converter 12, and a second heat exchange flow channel connected to the heat exchange circuit is formed in the water-cooled heat dissipation device.

[0062] According to the air compressor of the present invention, the housing is used to accommodate and protect the internal components of the air compressor. The heat exchange circuit is arranged in the housing, and absorbs and takes away heat through circulating flow, ensuring that the air compressor can operate stably within an appropriate temperature range, thereby cooling or regulating the heat generated during the operation of the air compressor. The electrical control cabinet assembly 1 is responsible for controlling the operation of the air compressor and is connected to the housing to improve the integration. By providing a heat dissipation device, the heat dissipation device is a water-cooled heat dissipation device that absorbs and takes away heat through coolant. After absorbing the heat inside the electrical control cabinet, the water-cooled heat dissipation device can transfer the heat to the coolant in the heat exchange circuit through the second heat exchange flow channel. The heat exchange circuit then takes away the heat and dissipates it into the environment, thereby completing the entire heat dissipation cycle, which not only improves the heat dissipation efficiency, but also realizes the effective management of heat inside the air compressor.

[0063] Since the air compressor according to the present invention includes the electric control cabinet assembly 1 in any one of the above embodiments, the air compressor according to the present application has a high degree of integration, effectively alleviates the heat dissipation problem, and realizes efficient and stable operation of the air compressor.

[0064] According to some embodiments of the present invention, Figure 5 As shown, a water cooling interface 118 is formed on the back of the cabinet body 11. The water cooling interface 118 is used to achieve communication between the hot water exchange circuit and the second heat exchange channel, thereby improving the connection efficiency and convenience between the water-cooling heat dissipation device and the hot water exchange circuit. The water cooling interface 118 includes a water inlet and a water outlet. The water inlet is used to introduce the coolant in the hot water exchange circuit into the second heat exchange channel in the water-cooling heat dissipation device inside the electrical control cabinet assembly 1, while the water outlet is used to guide the coolant that has absorbed and taken away heat from the second heat exchange channel and then flow it back into the hot water exchange circuit. The hot water exchange circuit can be connected to the second heat exchange channel of the water-cooling heat dissipation device inside the electrical control cabinet assembly 1 through the water inlet and the water outlet, forming a complete heat dissipation cycle, which not only simplifies the installation and maintenance process, but also ensures that heat can be efficiently transferred and dissipated inside the air compressor, further improving the stability and operating efficiency of the air compressor.
