[0032] In the related technologies, for electric control cabinets containing frequency converters, reactors and electric control systems, integration is the development trend. The integration of control systems can effectively reduce the size of the cabinet, optimize the assembly process, reduce development costs, and improve the aesthetics of the whole machine. However, integration will bring many problems, such as heat dissipation, electromagnetic compatibility, safety, etc. Therefore, how to optimize the internal structure of the cabinet, reduce the electromagnetic interference between the reactor, frequency converter and electric control system, improve the heat dissipation capacity of the cabinet, and ensure the safe operation of the electric control cabinet has become an urgent problem to be solved in this field.
[0033] Reference below Figure 1 An electric control cabinet assembly for an air compressor according to an embodiment of the present invention is described.
[0034] According to the present invention, an electric control cabinet assembly 1 for an air compressor includes: a cabinet body, in which a first installation area 111 and a second installation area 112 isolated from each other are formed; an inductor component 12 and an electric control component, which are respectively accommodated in the first installation area 111 and the second installation area 112 and isolated from each other; and a first heat dissipation device 141, which is arranged in the first installation area 111 and is used to dissipate heat for the inductor component 12.
[0035] Specifically, a first installation area 111 and a second installation area 112 are formed in the cabinet, which are isolated from each other. The reactance component 12 is arranged in the first installation area 111, and the electric control component is arranged in the second installation area 112, which helps to reduce the electromagnetic interference between the reactance component 12 and the electric control component, improve the stability and reliability of the overall system, and make the arrangement of the electric control component and the reactance component 12 more orderly, which is convenient for the wiring harness arrangement of the electric control component, and also convenient for subsequent maintenance and overhaul work. The reactance component 12 is usually used to limit the current change rate and reduce the impact of harmonics on the power grid, while the electric control component is responsible for controlling the operation of the air conditioner. The reactance component 12 and the electric control component are installed separately to avoid performance degradation or failure caused by mutual interference of electromagnetic fields, and because the cabinet is partitioned, it is easier to locate the problem when maintaining or overhauling the reactance component 12 and the electric control component, reducing interference with other components.
[0036] The reactance component 12 will generate a certain amount of heat during operation. If the heat cannot be dissipated in time, it may cause the temperature of the component to rise, affecting performance or even causing damage. The first heat dissipation device 141 is placed in the first installation area 111 to dissipate the heat of the reactance component 12 to prevent the reactance component 12 from being overheated and affecting performance. The first heat dissipation device 141 can be constructed as a heat dissipation component such as a fan or blower, which is easy to install and reduces costs.
[0037] According to the electric control cabinet assembly 1 for an air compressor of the present invention, a partition design is performed on the cabinet body, and a first installation area 111 and a second installation area 112 isolated from each other are formed inside the cabinet body. The reactance component 12 and the electric control component are respectively arranged in the first installation area 111 and the second installation area 112, so as to reduce the electromagnetic interference between the reactance component 12 and the electric control component, improve the stability and reliability of the overall system, facilitate the arrangement and subsequent maintenance of the reactance component 12 and the electric control component, reduce the maintenance cost, and extend the service life of the equipment. By arranging a first heat dissipation device 141 in the first installation area 111 to dissipate heat and cool the electric control component, the stable operation of the electric control component is ensured and its service life is extended.
[0038] According to some embodiments of the present invention, the electric control cabinet assembly 1 also includes a first partition 151, which is arranged in the first installation area 111 and divides the first installation area 111 into a first cavity 1111 and a second cavity 1112, and the reactance assembly 12 and the first heat dissipation device 141 are arranged in the first cavity 1111; the inverter 13 and the second heat dissipation device 142, the inverter 13 and the second heat dissipation device 142 are respectively accommodated in the second cavity 1112, and the inverter 13 and the reactance assembly 12 are isolated from each other.
[0039] Specifically, the first partition 151 is arranged in the first installation area 111 and divides the first cavity 1111 and the second cavity 1112 in the first installation area 111. The reactance component 12 and the first heat sink 141 are arranged in the first cavity 1111, and the inverter 13 and the second heat sink 142 are arranged in the second cavity 1112. This subdivision design makes more effective use of the internal space of the first installation area 111, and also provides a more independent working environment for the reactance component 12 and the inverter 13, ensuring the physical isolation between the inverter 13 and the reactance component 12, and reducing the electromagnetic interference between them. The second heat sink 142 is arranged in the second cavity 1112, ensuring that the inverter 13 can dissipate the generated heat in time when it is running at high load for a long time, avoiding the performance degradation or damage of the inverter 13 due to overheating. By arranging a first partition 151 in the first installation area 111, the first installation area 111 is divided into a first cavity 1111 and a second cavity 1112 which are isolated from each other, the inductor component 12 and the inverter 13 are isolated from each other, thereby reducing the electromagnetic interference between each other, improving the safety of the electric control cabinet component 1, and also improving the space utilization of the first installation area 111, so that the arrangement of the inductor component 12 and the inverter 13 is more compact, which is convenient for line control, maintenance and repair.
[0040] According to some embodiments of the present invention, a heat dissipation channel connecting the second cavity 1112 with the second installation area 112 is formed on the cabinet.
[0041] Specifically, a heat dissipation channel connected to each other is formed in the second cavity 1112 and the second installation area 112. The heat generated by the operation of the electronic control component can be transferred to the second cavity 1112 through the heat dissipation channel and discharged to the outside through the second heat dissipation device 142, so that the second heat dissipation device 142 can dissipate heat for the inverter 13 and the electronic control component at the same time, thereby improving the heat dissipation efficiency of the electric control cabinet component 1 and avoiding heat accumulation in the second installation area 112 to affect the working performance of the electronic control component. Among them, since the first installation area 111 and the second installation area 112 are isolated from each other to reduce the electromagnetic interference of the inverter 13 on the electronic control components, a plurality of heat dissipation holes spaced from each other can be opened between the second cavity 1112 and the second installation area 112 to form a heat dissipation channel while minimizing the interference of the inverter 13 on the electronic control components. In addition, the processing and forming process of the heat dissipation channel is simple, which is conducive to reducing the cabinet processing cost and shortening the production cycle. Since the second cavity 1112 and the second installation area 112 share the heat dissipation channel, there is no need to arrange a heat dissipation device separately in the second installation area 112, which is conducive to reducing the cabinet volume. The arrangement of the inverter 13, the inductor component 12 and the electronic control components is also more compact.
[0042] According to some embodiments of the present invention, the cabinet includes a cabinet body 11 and a second partition 152 , and a accommodating space is formed in the cabinet body 11 ; the second partition 152 is arranged in the accommodating space and divides the accommodating space into a first installation area 111 and a second installation area 112 , and a heat dissipation channel is formed on the second partition 152 .
[0043] Specifically, a storage space is formed inside the cabinet body 11, and the inverter 13, the reactance component 12, and the electric control component are respectively arranged in the storage space. A second partition 152 is arranged in the storage space to separate the storage space into a first installation area 111 and a second installation area 112, and the inverter 13 and the reactance component 12 are arranged in the first installation area 111, and the electric control component is arranged in the second installation area 112, so that the electric control component is isolated from the reactance component 12 and the inverter 13, and the electromagnetic interference of different reactance components 12 and the inverter 13 on the electric control component is reduced, and the wiring harness arrangement of the electric control component is more orderly and convenient. The reactance component 12, the inverter 13, and the electric control component are isolated from each other, which is also convenient for installation and maintenance. The heat dissipation channel is arranged on the second partition 152. A plurality of heat dissipation holes can be opened on the second partition 152 to form a heat dissipation channel connecting the second installation area 112 with the second cavity 1112. By setting the heat dissipation channel on the second partition 152, the heat in the second installation area 112 can be transferred to the second cavity 1112 through the heat dissipation channel, and dissipated to the external environment through the second heat dissipation device 142, which simplifies the cabinet structure, improves the heat dissipation efficiency, and makes the arrangement of the inverter 13 and the electronic control components more compact, which is beneficial to reducing the volume of the electronic control cabinet assembly 1.
[0044] According to some embodiments of the present invention, the second heat dissipation device 142 is configured as a heat dissipation fan, the rotation axis of the heat dissipation fan is perpendicular to the second partition plate 152, and the projection of the heat dissipation fan at least partially overlaps with the projection of the heat dissipation channel in the direction of the rotation axis.
[0045] Specifically, the second heat sink 142 is configured as a heat sink fan. The heat sink fan generates airflow by rotating to take away the heat from the heat source and dissipate it into the external environment. The heat sink fan has a simple structure, is easy to install, and reduces costs. The rotation axis of the heat sink fan is perpendicular to the second partition 152, which is convenient for installation and fixation of the heat sink fan, and improves the stability and reliability of the heat sink fan. The heat sink fan can generate an airflow perpendicular to the second partition 152 when working. Since the projection of the heat sink fan in the direction of the rotation axis and the projection of the heat dissipation channel are at least partially overlapped, the vertical airflow generated by the heat sink fan is convenient to guide the heat generated by the electronic control component out of the second installation area 112, reducing the loss and obstruction of the airflow during the transmission process, so that the heat can be transmitted more smoothly, and the heat dissipation efficiency is improved.
[0046] According to some embodiments of the present invention, the first heat sink 141 is configured as a water-cooled heat sink and / or an air-cooled heat sink.
[0047] Specifically, the first heat sink 141 can be constructed as a water-cooled heat sink or an air-cooled heat sink alone, or as a combination of a water-cooled heat sink and an air-cooled heat sink. The water-cooled heat sink takes away the heat generated by the reactance component 12 and dissipates it to the external environment through the circulation of water or other coolants, and has high heat dissipation efficiency. At the same time, water-cooled heat dissipation also has the advantages of low noise and precise temperature control. The air-cooled heat sink uses the airflow generated by the fan to take away the heat generated by the reactance component 12 and dissipate it to the air. The air-cooled heat sink has a simple structure and low cost. Using a water-cooled heat sink and an air-cooled heat sink to dissipate the heat of the reactance component 12 at the same time can make full use of the advantages of the two heat dissipation methods and further improve the heat dissipation capacity of the electric control cabinet component 1.
[0048] According to some embodiments of the present invention, a first wiring slot 171 and a second wiring slot 172 are provided in the second installation area 112; the electronic control component includes: a controller 16, the controller 16 is provided in the second installation area 112, and a high-voltage interface and a low-voltage interface are formed on the controller 16; a first electrical component 161, the first electrical component 161 is provided in the second installation area 112, and the first electrical component 161 is connected to the high-voltage interface through a high-voltage wiring harness; a second electrical component 162, the second electrical component 162 is provided in the second installation area 112, and the second electrical component 162 is connected to the low-voltage interface through a low-voltage wiring harness; wherein the high-voltage wiring harness and the low-voltage wiring harness are respectively accommodated in the first wiring slot 171 and the second wiring slot 172.
[0049] Specifically, a first wiring slot 171 and a second wiring slot 172 are formed in the second installation area 112, so that the high-voltage wiring harness and the low-voltage wiring harness are respectively accommodated in the first wiring slot 171 and the second wiring slot 172, reducing the mutual interference between the high-voltage wiring harness and the low-voltage wiring harness, improving the stability and reliability of the electric control component, and at the same time, making the arrangement of the wiring harness more neat and orderly, which is convenient for later maintenance. A high-voltage interface and a low-voltage interface are formed on the controller 16, which are used to connect the high-voltage wiring harness and the low-voltage wiring harness respectively, making the connection between the controller 16 and the electrical components more compact, reducing the length of the line and the number of connectors, and reducing the probability of failure. Among them, the first electrical component 161 is connected to the high-voltage interface of the controller 16 through the high-voltage wiring harness, and the second electrical component 162 is connected to the low-voltage interface of the controller 16 through the low-voltage wiring harness. When the electrical components need to be replaced or repaired, the corresponding lines and interfaces can be found more conveniently, reducing the time cost of finding and troubleshooting, and improving maintenance efficiency.
[0050] According to some embodiments of the present invention, the first wiring slot 171 and the second wiring slot 172 are arranged in parallel, the first wiring slot 171 and the second wiring slot 172 are respectively located on both sides of the controller 16 in the first direction, and the first electrical component 161 and the second electrical component 162 are respectively located on both sides of the controller 16 in the second direction, wherein the first direction is perpendicular to the second direction.
[0051] Specifically, the first wiring slot 171 and the second wiring slot 172 are arranged in parallel with each other, limiting the arrangement direction of the high-voltage wiring harness and the low-voltage wiring harness, so that the high-voltage wiring harness and the low-voltage wiring harness can be neatly arranged in a predetermined direction, further enhancing the orderliness inside the electric control cabinet assembly 1. At the same time, the wiring slots arranged in parallel are also convenient for installation and maintenance personnel to quickly identify and operate, thereby improving work efficiency. The first wiring slot 171 and the second wiring slot 172 are respectively located on both sides of the controller 16 in the first direction, and the first direction is the width direction of the cabinet body 11, ensuring that the high-voltage interface and the low-voltage interface have a shorter connection path with their respective wiring slots, reducing line loss and fault risks, and at the same time, making the controller 16 more centered in layout, which is convenient for connection and coordination with other electrical components. The first electrical component 161 and the second electrical component 162 are respectively located on both sides of the controller 16 in the second direction, the second direction is perpendicular to the first direction, and the second direction is the height direction of the cabinet body 11. The first electrical component 161 and the second electrical component 162 are respectively arranged on both sides of the height direction of the controller 16, which is beneficial to avoid mutual interference between the first electrical component 161 and the second electrical component 162, and is also convenient for connecting the wiring harnesses between the electrical components, thereby improving the utilization efficiency of the space in the second installation area 112 and making the parts arrangement of the electronic control components more compact.
[0052] According to some embodiments of the present invention, the second installation area 112 is also formed with a third wiring groove 173 and a fourth wiring groove 174 which are spaced apart from each other, the third wiring groove 173 is connected to the first wiring groove 171, and the fourth wiring groove 174 is respectively connected to the first wiring groove 171 and the second wiring groove 172, at least part of the high-voltage wiring harness passes through the third wiring groove 173 and is accommodated in the first wiring groove 171, at least another part of the high-voltage wiring harness passes through the fourth wiring groove 174 and is accommodated in the first wiring groove 171, and the low-voltage wiring harness passes through the fourth wiring groove 174 and is accommodated in the second wiring groove 172.
[0053] Specifically, the third wiring slot 173 and the fourth wiring slot 174 extend along the first direction respectively, a first electrical component 161 is arranged between the third wiring slot 173 and the fourth wiring slot 174, a controller 16 or a second electrical component 162 is arranged between two adjacent fourth wiring slots 174, the third wiring slot 173 is connected to the first wiring slot 171, and the high-voltage wiring harness connected to the first electrical component 161 and the high-voltage interface of the controller 16 enters the first wiring slot 171 through the third wiring slot 173, providing an additional path selection for the high-voltage wiring harness, optimizing the layout and direction of the cables, and avoiding the disordered entanglement of the high-voltage wiring harness and the low-voltage wiring harness inside the cabinet, the fourth wiring slot 174 is connected to the first wiring slot 171 and the second wiring slot 172 respectively, the high-voltage wiring harness and the low-voltage wiring harness enter the first wiring slot 171 and the second wiring slot 172 from directions away from each other through the fourth wiring slot 174 respectively, reducing the electromagnetic interference between the high-voltage wiring harness and the low-voltage wiring harness, and improving the safety and stability of the operation of the electric control cabinet.
[0054] In some embodiments, the first electrical component 161 can be constructed as a control transformer, that is, a transformer and an air switch. The main function of the transformer is to change the voltage without changing the frequency. The transformer can convert high voltage into low voltage, or convert low voltage electricity into high voltage electricity, so as to facilitate power transmission, distribution and use. In electronic circuits, transformers can be used to match the impedance between different circuits to achieve the effect of maximum power transmission. The transformer can also provide electrical isolation between two circuits to protect equipment safety and personnel safety; the air switch, also known as a circuit breaker, is a protective device that can automatically disconnect the circuit in the event of an overload or short circuit. When the current in the circuit exceeds a predetermined value, the air switch will automatically disconnect the circuit to prevent the electrical control component from overheating. When a short circuit occurs in the circuit, the air switch can quickly cut off the power supply to avoid equipment damage and safety accidents. Through the cooperation of the transformer and the air switch, the reliability and safety of the electrical control cabinet assembly 1 are improved.
[0055] In some embodiments, the second electrical component 162 is constructed as a current controller 16, namely, a contactor, a relay and an isolation module. The contactor, the relay and the isolation module are connected to the controller 16 through a high-voltage wiring harness and a low-voltage wiring harness, respectively. The contactor is an electrical device used to frequently connect and disconnect the main circuit. The contactor can carry a large current through its larger contacts and is suitable for switching the main circuit, that is, controlling the start and stop of the electronic control component; the contactor can control the circuit with a large current through a smaller control signal (usually provided by a PLC, a button or other control device), thereby realizing remote control and automated operation. The relay is an electrically controlled switch used to control a larger load or circuit through a smaller control signal. The relay can amplify a weak electrical signal to control a larger current or voltage. The relay can provide electrical isolation to protect the control system from the direct influence of high voltage or high current. The isolation module, or isolator, is used to eliminate interference during signal transmission to ensure the accuracy of the signal and the safety of the system. The isolation module can prevent mutual interference between the signal source and the load, especially when there is a voltage difference between the signal source and the load. The isolation module can effectively suppress electromagnetic interference and radio frequency interference to protect the integrity of the signal of the electronic control component.
[0056] In some embodiments, the electric control assembly further includes a main circuit breaker 181 , which is disposed on the cabinet body 11 and located on a side of the first wiring slot 171 away from the controller 16 in the first direction, and the main circuit breaker 181 is connected to the control transformer. The main circuit breaker 181 is connected to the control transformer. The main circuit breaker 181 can monitor the current passing through it. When the current exceeds the set safety threshold, it will automatically disconnect the circuit to prevent equipment damage or fire caused by overload. At the same time, when a short circuit occurs in the electronic control component, the main circuit breaker 181 can respond quickly and immediately disconnect the circuit to prevent damage caused by large current. The main circuit breaker 181 and the controller 16 are respectively located on both sides of the first wiring slot 171 in the first direction. The first wiring slot 171 separates the main circuit breaker 181 and the controller 16. Isolating the main circuit breaker 181 from the controller 16 can reduce the impact of electromagnetic interference on the controller 16 and ensure the accuracy of the control signal and the stability of the system. The main circuit breaker 181 may generate heat when disconnecting a large current. Setting it in a position with sufficient space can help dissipate heat and extend the life of the electronic control component.
[0057] In some embodiments, the electrical control component also includes a terminal block 182, which is arranged on the cabinet body 11 and is located on the side of the second electrical component 162 away from the controller 16 in the second direction. The terminal block 182 is arranged away from the controller 16 to reduce electromagnetic interference, and at the same time, it is convenient for maintenance personnel to approach the terminal block 182 for wiring or inspection without having to be too close to the controller 16 that may carry high voltage or large current, thereby ensuring the safety of maintenance personnel during maintenance. The terminal block 182 is respectively connected to the first electrical component 161, the second electrical component 162 and the controller 16. The terminal block 182 acts as a bridge, connecting the first electrical component 161, the second electrical component 162, the controller 16 and the external circuit.
