[0002] This application claims priority to Chinese patent application No. 202410668720.9, filed on May 27, 2024, entitled "Control cabinet and air conditioning assembly for air conditioning unit", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to the field of air conditioners, and in particular to a control cabinet for air conditioner components and an air conditioner component. Background Technology

[0004] In related technologies, traditional control cabinets generally use air cooling for heat dissipation. Since the frequency converter and reactor generate a lot of heat, air cooling requires opening heat dissipation holes on the cabinet body to exchange heat with the external environment. The design of heat dissipation holes on the cabinet body will reduce the protection level of the control cabinet and affect the stable operation of the frequency converter cabinet. At the same time, the heat dissipation effect of air cooling is poor. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of this invention is to provide a control cabinet for air conditioning unit components. According to this invention, the control cabinet, by placing the frequency converter and heat exchange components within an air duct, allows the heat exchange components to exchange heat with the airflow within the duct, reducing the airflow temperature. The low-temperature airflow can then exchange heat with the frequency converter, achieving heat dissipation for the frequency converter. This eliminates the need for ventilation holes on the cabinet body, improving the safety and reliability of the control cabinet.

[0006] The present invention also proposes an air conditioning unit assembly having the above-mentioned control cabinet.

Detailed Implementation

[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] The control cabinet according to an embodiment of the present invention is described below with reference to Figures 1-2.

[0026] The control cabinet 100 according to the present invention includes: a cabinet body 11, a frequency converter 13, an air duct component 12, and a heat exchange component 14. The cabinet body 11 has a mounting cavity formed therein. The frequency converter 13 is disposed in the mounting cavity and has a first cooling port 101 and a second cooling port 102. The air duct component 12 is disposed in the cabinet body 11 and surrounds at least a portion of the outer periphery of the mounting cavity. An air duct is formed in the air duct component 12. The inlet of the air duct communicates with the first cooling port 101, and the outlet of the air duct communicates with the second cooling port 102. At least a portion of the heat exchange component 14 is housed in the air duct and is used to exchange heat with the airflow in the air duct.

[0027] In some specific embodiments, the control cabinet 100 comprises a cabinet body 11, a frequency converter 13, an air duct component 12, and a heat exchange component 14. The cabinet body 11 has a recessed mounting cavity that houses the frequency converter 13. This mounting cavity provides some protection for the frequency converter 13, preventing external damage and improving its stability and reliability. The cabinet body 11 also has an air duct component 12 surrounding at least a portion of the outer periphery of the mounting cavity. A closed air duct is formed within the air duct component 12, and at least a portion of the frequency converter 13 is housed within it. The frequency converter 13 has a first cooling port 101 communicating with the air duct inlet and a cooling port 101 communicating with the air duct outlet. The second cooling port 102 and the heat exchange component 14 are located inside the air duct. The heat exchange component 14 can exchange heat with the airflow in the air duct, thereby cooling the airflow in the air duct. The cooled low-temperature airflow circulates in the closed air duct. When the low-temperature airflow passes through the inverter 13, it can enter the inverter 13 from the first cooling port 101 and exchange heat with the inverter 13, thereby reducing the temperature of the inverter 13 and achieving heat dissipation of the inverter 13. The high-temperature airflow inside the inverter 13 flows out of the inverter 13 through the second cooling port 102. The high-temperature airflow then flows through the heat exchange component 14 and exchanges heat with it to become low-temperature airflow. This cycle repeats, eliminating the need to open heat dissipation holes on the cabinet body 11 to allow the inverter 13 to exchange heat with the outside air, thus improving the safety and reliability of the inverter cabinet.

[0028] According to the present invention, a mounting cavity for accommodating a frequency converter 13 is formed on the cabinet body 11. An air duct component 12 is arranged around at least a portion of the outer periphery of the mounting cavity. A closed air duct is formed inside the air duct component 12. The air duct inlet is connected to the first cooling port 101 of the frequency converter 13, and the air duct outlet is connected to the second cooling port 102 of the frequency converter 13. A heat exchange component 14 is provided inside the air duct. The heat exchange component 14 can exchange heat with the airflow inside the air duct, thereby achieving cooling of the airflow inside the air duct. The cooled low-temperature airflow circulates in the closed air duct. When the low-temperature airflow passes through the frequency converter 13, it can enter the interior of the frequency converter 13 from the first cooling port 101 and exchange heat with the frequency converter 13, thereby achieving heat dissipation of the frequency converter 13. There is no need to open heat dissipation holes on the cabinet body 11 to allow the frequency converter 13 to exchange heat with the outside air, which improves the safety and reliability of the frequency converter cabinet.

[0029] According to some embodiments of the present invention, a plurality of mounting cavities are formed in the cabinet body 11, and a plurality of frequency converters 13 are configured to correspond one-to-one with the mounting cavities. Air duct components 12 are arranged around the outer periphery of each mounting cavity, and the air ducts in the plurality of air duct components 12 are independent of each other or connected to each other.

[0030] In some specific embodiments, the cabinet body 11 is provided with multiple mounting cavities, and multiple frequency converters 13 are constructed, with one frequency converter 13 corresponding to each mounting cavity. This realizes modular installation and management of the frequency converters 13, facilitating the repair and maintenance of each frequency converter 13. At the same time, integrating multiple frequency converters 13 into the same cabinet body 11 can significantly save installation space, especially for applications with limited space. This reduces the equipment footprint, helps optimize the layout, and improves space utilization. The centralized arrangement of multiple frequency converters 13 can reduce the complexity of external wiring, which not only reduces installation costs but also helps reduce electromagnetic interference and improve system safety. Each mounting cavity is surrounded by an air duct component 12, which can exchange heat with the corresponding frequency converter 13 to achieve cooling of the frequency converter 13 and ensure the cooling of each frequency converter 13. 3. Stable and reliable operation: For inverters 13 with low heat generation or low temperature control requirements, multiple air duct components 12 can be interconnected, allowing multiple inverters 13 to share low-temperature airflow, reducing the number of heat exchange components 14 within the air duct components 12 and lowering the complexity of the heat dissipation system design within the control cabinet 100. For inverters 13 with high heat generation or high heat dissipation requirements, multiple air duct components 12 can be set up independently, ensuring sufficient low-temperature airflow within each air duct component 12, guaranteeing the heat dissipation effect within each air duct component 12. At the same time, if one air duct fails (such as blockage or air leakage), it will not affect the normal heat dissipation of the corresponding inverters 13 by other air duct components 12, enhancing the fault isolation capability of the control cabinet 100 and improving the stability and reliability of the control cabinet 100 during operation.

[0031] According to some embodiments of the present invention, the control cabinet 100 further includes: a first circuit breaker 15, a second circuit breaker 16 and a busbar 17, wherein the first circuit breaker 15 and the second circuit breaker 16 are respectively disposed between two adjacent mounting cavities, and the first circuit breaker 15 and the second circuit breaker 16 are respectively connected to the frequency converter 13 in the two adjacent mounting cavities; the busbar 17 is respectively connected to the first circuit breaker 15 and the second circuit breaker 16.

[0032] In some specific embodiments, the control cabinet 100 is further equipped with a first circuit breaker 15, a second circuit breaker 16, and a busbar 17. The first circuit breaker 15 and the second circuit breaker 16 are respectively installed between two adjacent mounting chambers, arranged side-by-side. The first circuit breaker 15 and the second circuit breaker 16 can provide independent circuit protection for each inverter 13 in each mounting chamber. When a short circuit, overload, or other abnormal situation occurs in one of the inverters 13 or its circuit, the corresponding first circuit breaker 15 or second circuit breaker 16 will react quickly, cutting off the faulty circuit, thereby protecting other circuits and equipment. Unaffected, this improves the safety and reliability of the control cabinet 100. The busbar 17 is also located between two adjacent mounting cavities and below the first circuit breaker 15 and the second circuit breaker 16. During the wiring process of the frequency converter 13, the frequency converters 13 in the two adjacent mounting cavities are first connected to the first circuit breaker 15 and the second circuit breaker 16 respectively, and then the first circuit breaker 15 and the second circuit breaker are connected to the busbar 17 respectively. The user only needs to connect the main input cable to the busbar to supply power to the two frequency converters 13, which greatly simplifies the wiring work, reduces the possibility of installation errors, and improves the installation efficiency of the control cabinet 100.

[0033] According to some embodiments of the present invention, the cabinet body 11 is further provided with a low-voltage installation area 21 isolated from the installation cavity, and the low-voltage installation area 21 is provided with low-voltage control components and sensors connected to the frequency converter 13.

[0034] In some specific embodiments, a low-voltage installation area 21 is also formed on the cabinet body 11. The low-voltage installation area 21 is equipped with low-voltage control components and sensors connected to the frequency converter 13. The mounting cavity is arranged vertically and isolated from the low-voltage installation area 21. By isolating the frequency converter 13 from the low-voltage installation area 21, the electromagnetic interference of the main circuit of the frequency converter 13 to the low-voltage control components and sensors can be effectively reduced, ensuring the transmission quality of low-voltage signals and improving the accuracy and stability of the control cabinet 100. At the same time, since the low-voltage control components and sensors usually require relatively precise operation and periodic calibration, the isolation setting facilitates the centralized maintenance and debugging by technicians, reduces interference to the operation of the entire control cabinet 100, and improves the stability and reliability of the control cabinet 100 during operation.

[0035] According to some embodiments of the present invention, a wiring channel component 22 is formed in the low-voltage installation area 21. The wiring channel component 22 is arranged opposite to the busbar 17. A wiring channel is formed in the wiring channel component 22. On the one hand, the main input cable can pass through the wiring channel and connect to the busbar 17 to supply power to the frequency converter 13. The wiring channel can effectively protect the main input cable from physical damage, such as preventing damage to the main input cable caused by stepping, impact or scratches from sharp objects, thereby reducing the occurrence of electrical accidents and improving the safety of the control cabinet 100. At the same time, the wiring channel can also orderly store and manage the main input cable, avoiding the main input cable from being tangled and messy with the wiring harnesses of other electrical components, and facilitating the identification and maintenance of the main input cable. On the other hand, the wiring channel can also be used to accommodate the connection wires connected to the low-voltage control components and sensors. The wiring channel may also have an electromagnetic shielding function, which can be used to protect sensitive low-voltage signals from external electromagnetic interference, ensuring the stability and reliability of the operation of the control cabinet 100.

[0036] According to some embodiments of the present invention, the low-voltage control components and sensors are arranged in multiple rows. The multi-row layout can effectively utilize vertical space, especially in cabinets with limited space. This allows for the integration of more control components and sensors to the greatest extent possible without increasing the floor space of the cabinet body 11. The wiring channel component 22 is arranged between two adjacent rows, which can provide a direct and centralized wiring path for the low-voltage control components and sensors in each row, simplifying the wiring structure, reducing cable crossings and clutter, and facilitating the installation and maintenance of low-voltage control component cables and sensor cables.

[0037] According to some embodiments of the present invention, it further includes: a fan 19, wherein the fan 19 is configured as one or more and arranged inside the air duct.

[0038] In some specific embodiments, one or more fans 19 are also provided in the air duct. The fans 19 force the airflow to flow continuously in the air duct system by the power generated by the rotating blades, thereby increasing the airflow rate in the air duct. When the airflow passes through the heat exchange component 14, it will be cooled. Then, under the blowing of the fans 19, the low-temperature airflow flows through the inverter 13 and other heat-generating components in sequence and cools them down. Only one cooling is needed to cool both of them at the same time, thereby improving the heat dissipation effect and efficiency of the inverter 13 and other heat-generating components in the air duct.

[0039] According to some embodiments of the present invention, it further includes: a reactor 18, which is disposed in the air duct.

[0040] In some specific implementations, since the frequency converter 13 generates harmonic currents during operation, these harmonic currents can affect the power grid quality and the normal operation of the equipment. Installing a reactor 18 inside the cabinet body 11 can effectively suppress these harmonic currents, reduce pollution to the power grid, and improve the stability and power quality of the control cabinet 100. Simultaneously, placing the reactor 18 and the frequency converter 13 within the same cabinet body 11 can significantly save installation space, making the overall structure of the control cabinet 100 more compact. The reactor 18 is also housed within the air duct, allowing the reactor 18 and the frequency converter 13 to share the same air duct for heat dissipation. This simplifies airflow management and heat exchange design within the control cabinet 100, reduces the number of air ducts and heat exchange components 14, and lowers the complexity of the heat dissipation system design within the control cabinet 100. Furthermore, it reduces the need for separate cabinets, cables, installation accessories, etc., thereby lowering the overall manufacturing cost.

[0041] According to some embodiments of the present invention, a coil is provided inside the reactor 18. The coil is a component of the reactor 18 that generates a lot of heat during operation. By aligning the coil's winding direction with the airflow direction in the duct, the resistance of the airflow when passing through the gap between the coils is reduced, allowing the airflow to pass through the gap between the coils evenly. This increases the heat exchange area between the airflow and the coil, carrying away more of the heat generated by the coil during operation of the reactor 18, thereby improving the heat dissipation effect of the reactor 18.

[0042] According to some embodiments of the present invention, the heat exchange component 14 includes: a body portion and fins, the body portion being disposed on the cabinet body 11 and having at least a portion disposed within the air duct, and a cooling flow channel being formed within the body portion; and fins, the fins being disposed on the body portion and located within the air duct, at least a portion of the fins extending into the cooling flow channel and adapted to exchange heat with the heat dissipation medium within the cooling flow channel.

[0043] In some specific embodiments, the heat exchange component 14 mainly consists of a body and fins. The body is fixedly connected to the cabinet body 11, and at least a portion of the body is disposed in the channel. The body is usually the main structure of the heat exchange component 14. A cooling channel suitable for the flow of refrigerant (such as refrigerant, water or other cooling medium) is formed in the body. The fins are attached to the surface of the body, and at least a portion of the fins is housed in the air duct. At least another portion of the fins extends into the cooling channel. As the fan 19 or natural airflow drives the air (or other gas) to circulate in the closed air duct, when the airflow passes through at least a portion of the fins, the fin surface is in close contact with the airflow. Since at least another portion of the fins extends into the cooling channel and exchanges heat with the refrigerant, the fins can absorb the heat in the airflow and transfer the heat in the airflow to the refrigerant, thereby reducing the temperature of the airflow in the air duct. The low-temperature airflow can flow through multiple heat-generating components such as the inverter 13 and the reactor 18 and exchange heat with them, thereby achieving the cooling of multiple heat-generating components such as the inverter 13 and the reactor 18.

[0044] In addition, the fins are constructed as thin sheets, and the fins are usually made of materials with good thermal conductivity, such as aluminum or copper, which allows the fins to quickly absorb or dissipate heat, thereby enabling more effective heat exchange with the airflow in the air duct component 12 and improving the heat exchange effect of the heat exchange component 14. The fins have various shapes, such as straight fins, corrugated fins, spiral fins, serrated fins, etc. The shape of the fins is not limited in this application.
