Description

Technical Field

[0001] This utility model relates to heat dissipation structures, specifically to a heat dissipation structure for an active filter cabinet. Background Technology

[0002] An active power filter is a new type of power electronic device used to dynamically suppress harmonics and compensate reactive power. It is mainly used to improve the imbalance of the power system and reduce or eliminate the impact of harmonics on the power system and other equipment. Active power filters are installed in active power filter cabinets.

[0003] Existing active power filter cabinets use cooling fans installed at the exhaust vents on the top for heat dissipation. However, during operation, it was found that because the active power filter is located inside the cabinet, near the lower rear, heat dissipation through the top is inadequate. Furthermore, when the top cooling fan malfunctions, maintenance work requires climbing to a height, which takes an average of about 4 hours each time. During this process, the heat expelled by the active power filter accumulates at the cabinet door on the rear side, causing the internal temperature of the filter to rise, affecting the equipment's operating efficiency. The inability to address this promptly leads to a rapid increase in internal temperature, impacting normal equipment use, and prolonged overheating can cause component failure. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a heat dissipation structure for an active filter cabinet to achieve efficient heat dissipation of the active filter cabinet, and to enable timely repair and effectively shorten the repair time when the fan fails.

[0005] This utility model is achieved through the following technical solution:

[0006] A heat dissipation structure for an active filter cabinet includes a cabinet body with a door on the rear side. An active filter is installed in the cabinet cavity near the door. An exhaust vent is located on the top of the cabinet body. A heat dissipation area is provided on the door corresponding to the active filter, with multiple heat dissipation vents and mounting holes. A fan is installed at the mounting holes. A centralized heat-conducting cover is provided on the top wall of the cabinet cavity, located above the active filter. A heat-conducting channel with a smaller top and a larger bottom is formed inside the centralized heat-conducting cover, and the top of the heat-conducting channel is connected to the exhaust vent on the top of the cabinet body.

[0007] As a preferred embodiment of the heat dissipation structure of the aforementioned active filter cabinet, the fan is located inside the cabinet door and corresponds to the mounting hole, and louvers are provided on the outside of the mounting hole of the cabinet door.

[0008] As a preferred embodiment of the heat dissipation structure of the aforementioned active filter cabinet, two mounting holes are provided in the heat dissipation area of ​​the cabinet door, and a fan is provided at each of the two mounting holes.

[0009] As a preferred embodiment of the heat dissipation structure of the aforementioned active filter cabinet, the centralized heat-conducting cover is formed by four arc-shaped plates.

[0010] As a preferred embodiment of the heat dissipation structure of the aforementioned active filter cabinet, a dustproof mesh cover is provided on the top of the cabinet door around the exhaust vent.

[0011] This invention has the following advantages over the prior art:

[0012] This utility model provides a heat dissipation structure for an active filter cabinet. It eliminates the original fan on the top of the cabinet and adds a fan to the cabinet door corresponding to the active filter. This fan directly draws heat from the active filter inside the cabinet, improving the heat dissipation effect. Furthermore, the fan is mounted on the cabinet door, allowing for easy maintenance without the need for climbing. In addition, a centralized heat-conducting cover is installed on the top wall of the cabinet cavity. The funnel-shaped heat conduction channels within the cover guide rising hot air from the cabinet cavity to the exhaust vents for natural upward heat dissipation, supplementing the cooling provided by the fan on the rear cabinet door and further enhancing the overall heat dissipation effect of the cabinet cavity.

However, the protection scope of this utility model is not limited to the following embodiments.

[0018] See Figures 1 to 3This embodiment discloses a heat dissipation structure for an active filter cabinet. The active filter cabinet includes a cabinet body 1, with a cabinet door 2 hinged to the rear side of the cabinet body 1 via a hinge 3. An active filter 4 is installed in the inner cavity of the cabinet body 1 near the cabinet door 2. An exhaust vent 5 is provided on the top of the cabinet body 1, and a dustproof mesh cover 6 is provided around the exhaust vent 5 on the top of the cabinet door 2 to ensure heat dissipation while preventing dust from entering the cabinet body 1 through the exhaust vent 5. A heat dissipation area 7 is provided on the cabinet door 2 at the location corresponding to the active filter 4. Multiple heat dissipation vents 8 are provided in the heat dissipation area 7 of the cabinet door 2, and mounting holes are also provided in the heat dissipation area 7 of the cabinet door 2. A fan 9 is provided at the mounting hole of the cabinet door 2, located on the inner side of the cabinet door 2 and corresponding to the mounting hole. A louver 10 is provided on the outer side of the mounting hole of the cabinet door 2. In this embodiment, two mounting holes are provided in the heat dissipation area 7 of the cabinet door 2, and a fan 9 is provided at each of the two mounting holes. The fan 9 can be installed on the inner side of the cabinet door 2 by means of screw connection.

[0019] A centralized heat-conducting cover plate 11 is provided on the top wall of the inner cavity of the cabinet 1. The centralized heat-conducting cover plate 11 is located above the active filter 4. A heat-conducting channel 12 with a smaller top and a larger bottom is formed inside the centralized heat-conducting cover plate 11. The top of the heat-conducting channel 12 is connected to the exhaust hole 5 on the top of the cabinet 1. The centralized heat-conducting cover plate 11 is surrounded by four arc-shaped plates 13. Correspondingly, the heat-conducting channel 12 is also surrounded by the arc-shaped surfaces on the inner sides of the four arc-shaped plates 13. The top of the centralized heat-conducting cover plate 11 can be fixedly installed on the top wall of the inner cavity of the cabinet 1 by means of screw connection.

[0020] The heat dissipation structure provided in this embodiment eliminates the original fan 9 at the top of the cabinet 1 and adds a fan 9 to the cabinet door 2 corresponding to the active filter 4.
