Description

Technical Field

[0001] This invention belongs to the field of cooling and heat dissipation of electronic power cabinets, and particularly relates to a heat conduction and heat dissipation structure for power equipment cabinets and its heat conduction method. Background Technology

[0002] With the continuous development of electronic assembly technology, electronic power equipment is becoming increasingly miniaturized while systems are becoming more complex. High heat density has become an irresistible development trend. To meet the demands of high heat density and ensure normal system operation, traditional heat dissipation methods such as fans and heat sinks are constantly being innovated. Existing structures for heat dissipation inside power equipment cabinets generally rely on airflow. By supplying airflow into the cabinet, the airflow carries away and releases the heat inside, thus achieving heat dissipation. Simultaneously, the incoming airflow passes through a filter to prevent impurities from entering the cabinet. However, with prolonged airflow, the filter becomes clogged, accumulating impurities on its outer surface. This prevents airflow from entering the cabinet smoothly, drastically reducing the heat dissipation effect and affecting the normal operation of the power equipment inside. Therefore, it is necessary to upgrade and modify the cabinet's heat dissipation structure to avoid heat dissipation problems. Summary of the Invention

[0003] To address the shortcomings of the existing technology, the present invention provides a heat dissipation structure for power equipment cabinets that avoids airflow input blockage, has good heat conduction and heat dissipation effect, and is flexible and convenient to control.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0005] A heat dissipation structure for a power equipment cabinet includes a cabinet body, a ventilation box, a filter plate, and a cooling mechanism. The upper interior of the cabinet body has a top partition that divides the cabinet body into an upper drive box and a lower heat dissipation box. Multiple ventilation holes are evenly distributed from top to bottom on both sides of the heat dissipation box. A ventilation box is installed on the exterior of each side of the heat dissipation box. A filter plate is installed inside each ventilation box, facing the multiple ventilation holes. The cooling mechanism is installed inside the drive box. The cooling mechanism includes a rotating unit, an air intake box, an air inlet duct, a lifting ventilation duct, and a stretching connecting duct. The unit includes a ventilation connector pipe and a lifting unit. The rotating unit is installed inside the upper part of the drive box, with the upper end of the rotating unit connected to the air intake box, and one side of the air intake box connected to the air inlet pipe. Ventilation connector pipes are installed on the upper part of the ventilation box, with the upper ends of the ventilation connector pipes connected to the tension connecting pipes, and the upper ends of the tension connecting pipes connected to the lifting ventilation pipes. The lifting unit is installed inside the drive box and is connected to two lifting ventilation pipes. The rotating unit periodically drives the air intake box and the air inlet pipe to rotate to one side above the cabinet body, and the lifting unit drives the two lifting ventilation pipes to move upwards, so that the upper end of one of the lifting ventilation pipes is sealed and connected to the outer end of the air inlet pipe.

[0006] Furthermore, the rotating unit is a rotary motor; a lifting through plate is provided between the two lifting ventilation pipes; the lifting through plate slides up and down through the drive box; a floating sleeve is provided on the lifting through plate, and the upper end of the lifting unit is threadedly connected to the floating sleeve through a drive screw. The lifting unit drives the drive screw to rotate forward and backward, and the drive screw drives the floating sleeve, the lifting through plate, and the two lifting ventilation pipes to move up and down.

[0007] Furthermore, the drive box is equipped with a controller; the lifting unit is a rotary motor; the controller connects the lifting unit and the rotation unit and performs signal drive control at regular intervals.

[0008] Furthermore, the ventilation connector pipe is located on the upper outer side of the filter screen.

[0009] Furthermore, a sealing ring is provided at the outer end of the air inlet duct, and the air inlet duct is sealed and abutted against the lifting ventilation pipe through the sealing ring.

[0010] Furthermore, the drive box is provided with an openable door panel on the front or rear side.

[0011] Furthermore, the bottom of the ventilation box is provided with a lower pipe; the lower pipe is provided with an opening and closing valve.

[0012] Furthermore, the upper end of the rotating unit is connected to a support plate via a rotating shaft, and the upper end of the support plate is connected to an air duct.

[0013] A heat conduction method for a heat dissipation structure of a power equipment cabinet includes the following steps: Under normal operating conditions, the upper end of one of the lifting ventilation pipes is sealed and connected to the outer end of the air inlet pipe. Airflow enters the air inlet pipe through the induced draft box, and the air inlet pipe directs the airflow into one of the connected lifting ventilation pipes. This allows the airflow to pass through one ventilation box and its internal filter plate into the heat dissipation box, and then exits from the other ventilation box and its internal filter plate, thus achieving heat conduction and cooling. After a period of cooling operation, the controller controls the lifting unit to drive the two lifting ventilation pipes downwards. Then, the controller drives the rotating unit to start, causing the induced draft box and air inlet pipe to rotate to the other side of the upper part of the cabinet body. Finally, the controller drives the lifting unit again, which in turn drives the two lifting ventilation pipes upwards, sealing the upper end of the other lifting ventilation pipe with the outer end of the air inlet pipe. This creates a change in airflow direction, enabling periodic switching so that the two filter plates can be used alternately periodically, avoiding blockages that could lead to heat dissipation problems.

[0014] The beneficial effects of this invention are as follows:

[0015] To prevent impurities from clogging and depositing on the outside of the filter plates, thus hindering airflow, this invention designs two filter plates. Ventilation boxes are installed on both sides of the cabinet body, and the filter plates are placed inside these boxes. A rotating unit drives the air intake box and air inlet duct to rotate periodically, allowing the two filter plates to work alternately. This ensures that airflow alternates between the two sides of the filter plates, preventing impurities from clogging the filter plates by allowing airflow only to one side. This also ensures stable heat dissipation within the cabinet body. Attached Figure Description

[0023] like Figures 1 to 5 As shown, to facilitate the vertical movement control of the two lifting ventilation pipes 44, the rotating unit 41 is further configured as a rotary motor; a lifting through plate 441 is provided between the two lifting ventilation pipes 44; the lifting through plate 441 is slidably connected to the drive box 12; a floating sleeve 442 is provided on the lifting through plate 441; the upper end of the lifting unit 47 is threadedly connected to the floating sleeve 442 via a drive screw 471; the lifting unit 47 drives the drive screw 471 to rotate in both directions; the drive screw 471 drives the floating sleeve 442, the lifting through plate 441, and the two lifting ventilation pipes 44 to move vertically.

[0024] like Figures 1 to 5 As shown, for automatic control, the drive box 12 is further equipped with a controller 5; the lifting unit 47 is a rotary motor; the controller 5 connects the lifting unit 47 and the rotating unit 41 and performs signal drive control at regular intervals. Furthermore, the ventilation connector pipe 46 is located on the upper outer side of the filter screen plate 3.

[0025] like Figures 1 to 5As shown, to improve the airtightness of the ventilation, a sealing ring 431 is provided at the outer end of the air inlet duct 43, and the air inlet duct 43 is sealed and abutted against the lifting ventilation duct 44 through the sealing ring 431.

[0026] like Figures 1 to 5 As shown, a heat conduction method for a heat dissipation structure of a power equipment cabinet includes the following steps: Under normal operating conditions, the upper end of one of the lifting ventilation pipes 44 is sealed and connected to the outer end of the air inlet pipe 43. Airflow enters the air inlet pipe 43 through the air intake box 42. The air inlet pipe 43 then directs the airflow into one of the connected lifting ventilation pipes 44, allowing the airflow to pass through one of the ventilation boxes 2 and its internal filter plate 3 into the heat dissipation box 13.

This ensures stable heat dissipation inside the cabinet body 1.
