Filters are usually composed of components such as inductors and capacitors, which will generate a certain amount of heat when working, causing equipment overheating, reduced efficiency, and even failure.

[0058] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0059] like Figures 1 to 6 As shown, a first embodiment of the present invention provides a filter, the filter includes a shell structure 10 and a power device 20, the shell structure 10 encloses an installation cavity, and the power device 20 is located in the installation cavity; the shell structure 10 is provided with an air inlet and an exhaust port. The filter also includes a fan device 30 and an air guide plate 40, the fan device 30 and the air guide plate 40 are both arranged in the installation cavity, the fan blade portion of the fan device 30 is rotatably arranged and is located between the air inlet and the exhaust port; at least part of the air guide plate 40 is movably arranged to guide the airflow blown out by the fan device 30. The filter also includes a temperature detection member, the detection end of the temperature detection member is arranged on the power device 20 and is used to detect the temperature of the power device 20; the temperature detection member and the power device 20 are both multiple, and the multiple temperature detection members and the multiple power devices 20 are arranged one-to-one.

[0060] The filter provided by the first embodiment of the present invention can achieve accurate guidance of the airflow through the setting of the fan device 30 and the air guide plate 40, in conjunction with the setting of the temperature detection member, thereby avoiding the waste of heat dissipation resources, effectively improving the heat exchange efficiency inside the filter, and reducing the temperature of the power device 20, thereby extending the service life of the filter. Such a setting can adjust the fan speed and airflow guidance according to the real-time load and temperature changes of the power device 20, ensure that the temperature of key components remains within a safe range, improve the stability and energy efficiency of the filter, and reduce operating costs. Through this design, the filter can adjust the heat dissipation strategy according to the real-time temperature of the power device 20, effectively prevent the power device 20 from overheating, and improve the heat dissipation efficiency of the filter and the service life of the power device 20. This filter is suitable for various occasions that require high power and high efficiency, such as data centers, communication base stations, industrial automation equipment, etc. Therefore, the filter provided by this embodiment can solve the technical problem of low heat dissipation efficiency of the filter in the prior art.

[0061] Specifically, the filter also includes an air guide driver and a control member, the driving end of the air guide driver is connected to the air guide plate 40, and the driving end of the air guide driver is movably arranged. The temperature detection member and the air guide driver are both electrically connected to the control member, and the control member is used to drive the driving end of the air guide driver to operate according to the detection result of the temperature detection member. With such a setting, the filter can realize intelligent heat dissipation control, which can not only automatically adjust the fan speed according to the temperature of the power device 20, but also dynamically adjust the angle of the air guide plate 40 to ensure that the airflow is directly aimed at the high temperature area, further improving the heat dissipation efficiency. It is suitable for filters that need to work in complex environments and with different power requirements, such as outdoor environments with large temperature changes or in industrial equipment with large load fluctuations.

[0062] Specifically, the air guide driving member is a motor. When the control member issues an adjustment instruction, the driving end of the motor starts to rotate. The rotation of the driving end of the motor is transmitted to the air guide plate 40 through the transmission device, thereby changing the angle of the air guide plate 40.

[0063] Specifically, the plurality of power devices 20 include a plurality of first power devices 21 and a plurality of second power devices 22, wherein the plurality of first power devices 21 are arranged at intervals along a preset direction; the plurality of second power devices 22 are arranged at intervals along a preset direction; the second power device 22 is arranged on a side of the first power device 21 close to the air guide plate 40, and the power of the first power device 21 is greater than the power of the second power device 22. The air guide plate 40 has a first end 41 and a second end 42 arranged opposite to each other, the second end 42 is located on a side of the first end 41 close to the second power device 22, the second end 42 extends into the gap between two adjacent second power devices 22 and is arranged at intervals with an end of the first power device 21 close to the second power device 22. With such an arrangement, by separately arranging the high-power first power device 21 and the low-power second power device 22, it is possible to effectively avoid heat concentration, optimize the heat dissipation path, ensure uniform distribution of heat energy, and improve overall heat dissipation efficiency and stability. The design of the air guide plate 40 can accurately guide the flow of cold air, ensuring that the cold air flows preferentially to the high-power first power device 21, thereby improving the heat exchange efficiency through the optimized air flow channel, while avoiding air flow short circuit, ensuring the uniformity and effectiveness of heat dissipation.

[0064] Specifically, the plurality of power devices 20 include a plurality of first power devices 21 and a plurality of second power devices 22, wherein the plurality of first power devices 21 are arranged at intervals along a preset direction; the plurality of second power devices 22 are arranged at intervals along a preset direction; the second power device 22 is arranged on a side of the first power device 21 close to the air guide plate 40, and the power of the first power device 21 is greater than the power of the second power device 22. Among them, along the preset direction, the gap between two adjacent first power devices 21 is smaller than the gap between two adjacent second power devices 22. With such a setting, by separating the high-power first power device 21 and the low-power second power device 22, heat concentration can be effectively avoided, the heat dissipation path can be optimized, the heat dissipation path can be ensured, the heat energy can be evenly distributed, and the overall heat dissipation efficiency and stability can be improved. The setting of the gap size can reduce the direct heat transfer between the high-power power devices 20, while allowing more air to flow through the high-power power devices 20, thereby improving the heat dissipation efficiency, reducing the risk of local overheating, and ensuring that the filter module can operate stably under high load. Such an arrangement achieves effective management and uniform distribution of heat inside the filter, improves heat dissipation efficiency, and at the same time ensures optimal utilization of cold air through precise airflow control of the air guide plate 40, reduces energy loss, and enhances equipment reliability and service life.

[0065] Specifically, at least part of the air guide plate 40 is arranged on a side of the fan device 30 close to the power device 20; one end of the air guide plate 40 is connected to the housing structure 10, and the other end of the air guide plate 40 forms at least part of the air guide plate 40, and the other end of the air guide plate 40 is rotatably arranged. With such a structural arrangement, the cooling air can be guided to flow directly to the high-power power device 20, avoiding the ineffective circulation of the airflow or the waste in the non-critical area, ensuring that the cold air can effectively and directly cool the heating element, and improving the heat dissipation efficiency. The other end of the air guide plate 40 is rotatably arranged, which means that the air guide plate 40 can dynamically adjust its angle according to the actual heat dissipation demand and temperature change. This design enables the heat dissipation system to dynamically adjust the airflow direction and flow rate according to the ambient temperature, the heat consumption change of the power device 20 and the workload, avoiding the heat dissipation dead angle, and ensuring that all power devices 20 can be properly cooled. In complex environmental conditions such as airborne and outdoor, this flexibility is particularly important and can improve the adaptability and reliability of the heat dissipation system. The connection design of the air guide plate 40 and the housing structure 10 and its rotatable characteristics, combined with temperature feedback control, can achieve more precise heat dissipation control. When the system detects that the temperature of a certain part of the power device 20 is too high, the airflow in this area can be increased by adjusting the angle of the air guide plate 40 to achieve a rapid cooling effect. This intelligent control can effectively avoid overheating and extend the service life of the equipment.

[0066] Specifically, the air guide plate 40 is made of polybutylene terephthalate (PBT). With such a configuration, the polybutylene terephthalate material has good heat resistance and mechanical strength, is suitable for filters working in high temperature and vibration environments, and prolongs the service life of the filter.

[0067] Specifically, one end of the air guide plate 40 is fixed to the inner side surface of the shell structure 10 through a transition structure.

[0068] Specifically, the filter also includes a dust filter 50, and dust filters 50 are provided at both the air inlet and the air outlet. With such a setting, the dust filter 50 can effectively prevent external dust and impurities from entering the interior of the filter, reduce the pollution and wear of the internal electronic components, maintain the unobstructed heat dissipation duct, and improve the heat dissipation efficiency. At the same time, this also helps to reduce maintenance requirements and extend the service life of the equipment. Especially in outdoor or dusty environments, the importance of the dust filter 50 is particularly prominent, which ensures that the filter can work stably under harsh conditions.

[0069] Specifically, the fan device 30 includes an inlet fan and an outlet fan, wherein the inlet fan is arranged at the air inlet, and the outlet fan is arranged at the exhaust port. With such an arrangement, by respectively arranging the inlet fan and the outlet fan at the air inlet and the exhaust port, forced air circulation can be achieved, ensuring that cold air enters from the air inlet and hot air is discharged from the exhaust port, thereby forming an effective heat dissipation duct. This layout optimizes the airflow path, avoids the mixing of cold and hot air, and improves the heat dissipation efficiency. At the same time, the independent arrangement of the inlet and outlet fans also facilitates independent control according to actual heat dissipation requirements, further improving the intelligence and flexibility of the heat dissipation device, and ensuring that the filter can effectively dissipate heat under different load and environmental conditions and maintain a stable operating temperature.

[0070] Specifically, the filter also includes a heat sink fin, which is arranged on at least part of the power device 20 and protrudes from the surface of at least part of the power device 20. The heat sink fin is made of aluminum alloy material. With such a setting, the heat sink fin made of aluminum alloy has high thermal conductivity and good thermal conductivity, and can quickly transfer the heat generated by the power device 20 to the fin surface, increase the heat dissipation area, and effectively improve the heat dissipation efficiency. In addition, the protruding design increases the contact area between the power device 20 and the ambient air, promotes heat exchange, and further enhances the heat dissipation effect.

[0071] Specifically, the filter also includes a heat sink fin, which is arranged on at least part of the power device 20 and protrudes from the surface of at least part of the power device 20. The contact thermal resistance between the heat sink fin and the power device 20 is greater than or equal to 80W / (m·K) and less than or equal to 90W / (m·K). With such a setting, by strictly controlling the contact thermal resistance value, it is ensured that there is good thermal conductivity between the heat sink fin and the power device 20. Within this thermal resistance range, the heat generated by the power device 20 can be transferred to the heat sink fin more smoothly, accelerating the heat transfer process from the power device 20 to the heat sink fin, thereby effectively reducing the temperature of the power device 20 and ensuring its stable operation in the harmonic control of the high-voltage power grid.

[0072] Specifically, the contact thermal resistance between the heat dissipation fin and the power device 20 is 82 W / (m·K).

[0073] Specifically, the filter further includes a heat sink fin, which is arranged on at least a portion of the power device 20 and protrudes from the surface of at least a portion of the power device 20. The heat sink fin is fixedly connected to the housing structure 10. With such a structural arrangement, the heat sink fin is directly fixedly connected to the housing structure 10, which can not only stabilize the position of the fin and prevent displacement in vibration or wind environments such as airborne and outdoor, but also use the housing structure 10 as an extended heat sink surface of the heat sink fin, increase the heat dissipation path, help to quickly and evenly distribute the heat to the entire housing, and use the heat dissipation capacity of the housing to assist the heat sink fin, and jointly improve the heat dissipation efficiency and stability of the entire system.

[0074] Specifically, the heat dissipation fins are connected to the housing structure 10 by screws, and the heat dissipation fins are fixed on the bottom ribs of the housing structure 10 .

[0075] In this embodiment, the housing structure 10 includes a cover 11 and a housing 12, and the cover 11 and the housing 12 are sealed and connected by a connector. Among them, a part of the connector is used to be arranged in the cover 11, and the other part of the connector is used to be arranged in the housing 12. With such a structural setting, the cover 11 and the housing 12 are sealed and connected through the connector, which not only ensures the structural integrity and stability of the device, but also prevents the connector from affecting the sealing of the housing structure 10 due to changes in the external environment (such as temperature and pressure fluctuations) by placing different parts of the connector in the cover 11 and the housing 12, thereby ensuring the operating environment of the internal electronic components, preventing external pollutants such as dust and moisture from entering, and improving the protection level and reliability of the filter heat dissipation device.

[0076] Specifically, there are multiple connecting pieces. Specifically, the connecting pieces are multiple cross recessed countersunk screws. Multiple cross recessed countersunk screws penetrate the through hole of the cover 11 and the through hole of the shell 12 from top to bottom. The through hole of the cover 11 and the through hole of the shell 12 are both provided with threads, and the cross recessed countersunk screws are tightened and positioned through threaded connection. The cross recessed countersunk screws are not protruding from the outer surface of the cover 11, and are not protruding from the outer surface of the shell 12. Specifically, there are 40 cross recessed countersunk screws.

[0077] In this embodiment, the housing structure 10 includes a cover 11 and a housing 12, and the cover 11 and the housing 12 are sealed and connected by a connector. The housing structure 10 also includes a waterproof seal, which is arranged at the connection between the cover 11 and the housing 12. With such a structural arrangement, the arrangement of the waterproof seal further enhances the sealing performance of the housing structure 10, especially under outdoor conditions, which can effectively prevent rainwater, moisture, etc. from invading the interior of the housing, protect the internal circuit and the power device 20 from being affected by the humid environment, ensure the stability and durability of the filter in harsh environments, and extend the service life of the equipment.

[0078] Specifically, the waterproof sealing part is a waterproof adhesive layer, and the waterproof sealing part is arranged around the connection between the cover 11 and the shell 12 .

[0079] In this embodiment, the housing structure 10 includes a cover 11 and a housing 12, and the cover 11 and the housing 12 are sealed and connected by a connector. Among them, the surface of the connector is coated with anti-loosening glue. With such a structural setting, the application of anti-loosening glue can effectively prevent the cover 11 and the housing 12 from loosening under the influence of factors such as vibration and temperature changes, ensure the tightness of the connector after long-term operation, and improve the stability and safety of the equipment in vibration environments such as airborne and vehicle-mounted. At the same time, the use of anti-loosening glue also simplifies the installation and maintenance process and reduces maintenance costs.

[0080] Specifically, an output interface 60 is provided on one side of the housing structure 10, and the output interface 60 is electrically connected to the power device 20. The filter also includes at least two positioning guide pins 70, and the at least two positioning guide pins 70 are used to guide and position the components to be installed. The positioning guide pins 70 are arranged on one side of the housing structure 10 and protrude from the housing structure 10. The output interface 60 is located between one and the other of the at least two positioning guide pins 70. One and the other of the at least two positioning guide pins 70 are arranged relative to each other. With such an arrangement, the direct electrical connection between the output interface 60 and the power device simplifies the circuit layout, reduces the delay and interference of the internal signal transmission, and improves the response speed and signal integrity of the filter. At the same time, the arrangement of the positioning guide pins 70 ensures the precise alignment of the filter during installation, avoids connection problems caused by mechanical errors, and improves the installation efficiency and reliability of the equipment. The relative arrangement of the two positioning guide pins 70 and the design of the output interface 60 being located in the middle make the filter directional during installation, prevent incorrect installation, and ensure the normal operation of the equipment.

[0081] Specifically, there are multiple output interfaces 60, and the multiple output interfaces 60 are arranged in an array. Specifically, there are 16 output interfaces 60.

[0082] Specifically, a communication interface and an I / O (input / output) terminal interface are disposed on one side of the housing structure 10 , and a dial switch and a status indicator light are disposed on the other side of the housing structure 10 .

[0083] Specifically, the shell structure 10 also includes a heat insulation board, which is arranged in the installation cavity. The heat insulation board is used to enclose a heat insulation space, and the power device 20 is used to be arranged in the heat insulation space. The heat insulation board is provided with a heat dissipation port for air circulation. With such a configuration, the heat insulation board effectively isolates the thermal influence of the external environment on the power device 20, especially in high temperature or large temperature difference environment, thereby protecting the stable operation of the power device 20. At the same time, it also isolates the influence of the heat-generating power device 20 on other structures in the filter. At the same time, by providing a heat dissipation port on the heat insulation board, it is ensured that the internal heat can be effectively discharged through the designed air duct structure, achieving a good balance between heat dissipation performance and heat insulation effect, and improving the overall thermal management and environmental adaptability of the filter.

[0084] Specifically, the housing structure 10 further includes a handle structure 80, which is disposed on one side of the housing structure 10 and outside the installation cavity. With such a structural arrangement, the handle structure 80 provides a convenient gripping point, which facilitates the handling and installation of the filter, especially in a narrow space. The external position design of the handle structure 80 avoids contact with internal electronic components, prevents damage to precision components during the handling of the device, and enhances the operability and safety of the device.

[0085] Specifically, the handle structure 80 is in a shape that is easy to hold, such as a semicircular, rectangular or ergonomic shape, to provide a good grip and ease of operation. The handle structure 80 is located on one side of the shell structure 10. Specifically, it is designed to be in a position that does not interfere with the internal installation cavity, ensuring the characteristics of its external setting and preventing the internal electronic components from being affected or damaged during transportation or installation. The handle structure 80 is connected to the shell structure 10 through a fixed bracket, which can be made of metal or high-strength plastic to ensure the stability and durability of the handle. The fixed bracket includes fasteners, which are used to fix it to the shell structure, while ensuring the strength of the connection point to prevent breakage or loosening when subjected to large external forces.

[0086] Specifically, the shell structure 10 also includes a locking structure 90, and the locking portion of the locking structure 90 is used to lock and connect with the rack. The shell structure 10 includes a first side portion and a second side portion that are arranged opposite to each other, and the locking structure 90 is provided on both the first side portion and the second side portion. With such a structural arrangement, the locking structure 90 is symmetrically distributed on both sides of the shell structure 10, providing a uniform mechanical fixing force, avoiding structural distortion or stress concentration that may be caused by unilateral fixing, and enhancing the connection stability between the filter and the rack. This distribution also ensures the firmware security in a vibration environment, and reduces the risk of loose connection caused by mechanical vibration under complex working conditions such as airborne and outdoor conditions.

[0087] Specifically, the locking structure 90 includes a plurality of locking pins, which are used to be locked with locking holes on the frame to achieve a quick and stable connection.

[0088] Specifically, the housing structure 10 has a length of 680 mm, a width of 538 mm, and a height of 200 mm. The total power consumption of the filter is 175 W. Specifically, the housing structure 10 is made of 6063 aluminum alloy material, and its thermal conductivity is 202 W / (m·K).

[0089] In this embodiment, the filter further includes a circuit board 100, which is disposed in the mounting cavity. Both sides of the circuit board 100 are used to connect with the power device 20.
