Description

Technical Field

[0001] This utility model relates to the field of cabinet heat dissipation technology, specifically, to a cabinet heat dissipation structure. Background Technology

[0002] With the rapid development of information technology, data centers are constantly expanding in scale. Data centers house a large number of servers, storage devices, and other electronic equipment. These devices generate a significant amount of heat during operation. To ensure the operation of the server racks and prevent accidental fires, fans are typically installed inside the racks for heat dissipation. However, after prolonged use, dust from the environment enters the racks with the airflow. As the fans draw air into the racks, dust adheres to the surface of the filter plates. Over time, this dust accumulation clogs the filter pores, reducing the rate of air exchange between the inside and outside of the racks and thus decreasing heat dissipation efficiency. Therefore, we propose a rack heat dissipation structure. Utility Model Content

[0003] The purpose of this utility model is to provide a cabinet heat dissipation structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides a cabinet heat dissipation structure, including a cabinet shell, an air inlet on one side of the cabinet shell, an air outlet on the other side of the cabinet shell, and a heat dissipation device inside the cabinet shell for dissipating heat from the interior of the cabinet shell. The heat dissipation device includes a frame fixedly installed on the inner wall of the cabinet shell, and a filter plate fixedly connected inside the frame. A cleaning device and a driving device are provided inside the cabinet shell. The cleaning device is used to clean the surface of the filter plate, and the driving device is used to drive the cleaning device. The cleaning device includes a cleaning plate that slides on one side of the filter plate, and the surface of the filter plate is scraped by the sliding of the cleaning plate. A slider is slidably arranged inside the cabinet shell near the upper side, and a connecting rod is hinged between the cleaning plate and the slider.

[0005] As a further improvement to this technical solution, a guide groove is provided on the inner surface of the frame, and a guide block is slidably disposed inside the guide groove, and the guide block is fixedly installed on the cleaning plate.

[0006] As a further improvement to this technical solution, a limiting groove is provided on the inner wall of the cabinet shell, and a limiting block is slidably arranged inside the limiting groove, with the limiting block fixedly installed on the slider.

[0007] As a further improvement to this technical solution, the driving device includes two screws rotatably disposed inside the cabinet shell, two sliders are respectively threaded to the outside of the two screws, a driven gear is fixedly connected to one adjacent end of each of the two screws, a driving gear meshes between the two driven gears, a second motor is fixedly connected to the upper side of the cabinet shell, and the end of the output shaft of the second motor passes through the cabinet shell and is fixedly connected to the driving gear.

[0008] As a further improvement to this technical solution, a perforated mesh located on one side of the filter plate is fixedly installed inside the frame, and a first motor is fixedly connected to the side of the perforated mesh away from the filter plate, and a cooling fan is fixedly connected to the end of the output shaft of the first motor.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] In this cabinet heat dissipation structure, the connecting rod is hinged to the cleaning plate and the slider. When the two sliders move to the side away from each other, they push the connecting rod to move. The guide block slides inside the guide groove to guide the cleaning plate. During the movement, the cleaning plate scrapes off the dust attached to the surface of the filter plate, preventing the filter holes of the filter plate from being blocked by dust accumulation over a long period of time, which would reduce the speed of air exchange between the inside and outside of the cabinet and thus reduce the heat dissipation efficiency.

[0019] Example 1

[0020] Please see Figures 1-4 As shown, this embodiment provides a cabinet heat dissipation structure, including a cabinet shell 1. An air inlet 5 is provided on one side of the cabinet shell 1, and an air outlet 6 is provided on the other side. The air inlet 5 and air outlet 6 facilitate air exchange between the inside and outside of the cabinet shell 1, expelling hot air from inside the cabinet shell 1 to achieve heat dissipation. A heat dissipation device 2 is installed inside the cabinet shell 1 to dissipate heat from the inside of the cabinet shell 1. The heat dissipation device 2 includes a frame 21 fixedly installed on the inner wall of the cabinet shell 1. A filter plate 25 is fixedly connected inside the frame 21, and the filter plate 25 is used to filter the air expelled from the cabinet shell 1. For filtration, a perforated mesh 22 located on one side of the filter plate 25 is fixedly installed inside the frame 21. A first motor 23 is fixedly connected to the side of the perforated mesh 22 away from the filter plate 25. A cooling fan 24 is fixedly connected to the end of the output shaft of the first motor 23. The cooling fan 24 driven by the first motor 23 accelerates the air circulation inside the cabinet shell 1, thereby increasing the heat dissipation effect of the device on the cabinet shell 1. When the cabinet shell 1 is installed, a dustproof mesh should be installed on the side of the air inlet 5 to reduce the dust entering the cabinet shell 1 with the air and prevent dust from adhering to the surface of the internal parts of the cabinet shell 1, which would lead to a deterioration in the heat dissipation effect of the cabinet shell 1.

[0021] The cabinet shell 1 houses a cleaning device 3 and a driving device 4. The cleaning device 3 cleans the surface of the filter plate 25, and the driving device 4 drives the cleaning device 3. The cleaning device 3 includes a cleaning plate 32 that slides on one side of the filter plate 25. A guide groove 35 is formed on the inner surface of the frame 21, and a guide block 36 is slidably disposed inside the guide groove 35. The guide block 36 is fixedly mounted on the cleaning plate 32. When the cleaning plate 32 moves, the guide block 36 slides within the guide groove 35 to guide the cleaning plate 32, preventing it from shifting during movement and thus ensuring effective cleaning of the filter plate 25 surface. The cleaning plate 25 is scraped against the surface of the filter plate 25. A slider 33 is slidably installed near the upper side inside the cabinet shell 1. A limit groove is opened on the inner wall of the cabinet shell 1, and a limit block 37 is slidably installed inside the limit groove. The limit block 37 is fixedly installed on the slider 33. When the slider 33 slides, the slider 33 is guided and limited by the sliding of the limit block 37 in the limit groove to prevent the slider 33 from sliding sideways. A connecting rod 34 is hinged between the cleaning plate 32 and the slider 33. When the slider 33 slides, the connecting rod 34 and the hinge between the slider 33 and the cleaning plate 32 drive the cleaning plate 32 to move downward, so that the cleaning plate 32 scrapes the surface of the filter plate 25, thereby cleaning the surface of the perforated mesh 22.

[0022] The drive device 4 includes two screws 41 rotatably mounted inside the cabinet shell 1, and two sliders 33 threadedly connected to the outside of the two screws 41. Each adjacent end of the two screws 41 is fixedly connected to a driven gear 42, and a driving gear 43 meshes between the two driven gears 42. A second motor 44 is fixedly connected to the upper side of the cabinet shell 1. The output shaft end of the second motor 44 passes through the cabinet shell 1 and is fixedly connected to the driving gear 43. When the second motor 44 starts, it drives the screws 41 to rotate through the meshing between the two driven gears 42 and the driving gear 43, and drives the sliders 33 to slide through the threaded connection between the screws 41 and the sliders 33, thereby driving the sliding of the cleaning plate 32. The structure is simple and stable and has practicality.

[0023] In this embodiment, the cabinet heat dissipation structure, when in use, activates the second motor 44, which drives the screw 41 to rotate through the meshing between the driven gear 42 and the driving gear 43. The screw 41 and the slider 33 are connected by a thread, causing the slider 33 to slide inside the cabinet shell 1. When the two sliders 33 slide to the side away from each other, the cleaning plate 32 is moved by the hinge between the connecting rod 34 and the cleaning plate 32 and the slider 33. The guide block 36 slides inside the guide groove 35 to guide and limit the cleaning plate 32, so that the cleaning plate 32 moves in the vertical direction and scrapes the surface of the filter plate 25 to clean the dust attached to the surface of the filter plate 25. This prevents the dust from clogging the filter holes of the filter plate 25, which would reduce the ventilation volume and reduce the heat dissipation effect of the device.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
