A cabinet ventilation device

Abstract

This utility model discloses a cabinet ventilation device, including a cabinet body and a door panel. A dustproof air intake device is provided in the middle of the door panel and is fixedly connected to the door panel. The dustproof air intake device is equipped with a detachable filter. This patent, by setting up a dustproof air intake device, uses an internal fan to draw in air, which is directly blown onto the electronic components of the cabinet, thus cooling the electronic components. In addition, the dustproof air intake device is equipped with filter cotton to isolate dust in the air, thereby reducing dust inside the cabinet and keeping the machine inside clean. Furthermore, since the machine generates heat inside the cabinet, hot air will rise. An exhaust vent is provided at the top of the machine, which is connected to a pipe and a fan to exhaust the hot air. The incoming fresh air cools the inside of the cabinet, achieving heat exchange.

Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, specifically to a cabinet ventilation device. Background Technology

[0002] After a period of use, existing electrical cabinets often accumulate a lot of dust. Over time, the more dust accumulates, the more it affects electronic components and hinders heat dissipation. Cleaning is also very troublesome because the electronic components cannot be washed with water, and wiping with a cloth can only clean some higher surfaces, leaving smaller areas uncleanable. Therefore, we need to solve the technical problem of dust prevention for computer cabinets. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a cabinet ventilation device that solves the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cabinet ventilation device, comprising a chassis and a door panel, wherein a dustproof air inlet device is provided in the middle of the door panel, the dustproof air inlet device is fixedly connected to the door panel, and the dustproof air inlet device is provided with a detachable filter device.

[0005] Furthermore, the dustproof air intake device is provided with a fan and a cavity on the upper and lower sides. The upper and lower ends of the cavity are provided with channels that connect to the ventilation openings of the fan. The cavity is provided with a space of a size that is adapted to the filter device.

[0006] Furthermore, the filter device has an internal cavity through which filter cotton is placed, and one side of the filter device has a protruding edge that abuts against one side edge of the cavity.

[0007] Furthermore, hooks are provided on both sides of the convex edge of the filter device, and latches are provided on both sides of the outer side of the cavity, so as to lock and unlock through the latches and hooks.

[0008] Furthermore, the fan is fixed to the upper and lower sides of the dustproof air intake device by screws, and the fan is connected to a power cord.

[0009] Furthermore, the upper part of the chassis is provided with an exhaust vent, which is connected to the internal space of the chassis, allowing the hot air inside the chassis to be ventilated. Beneficial effects

[0010] This utility model provides a cabinet ventilation device. Compared with the prior art, it has the following beneficial effects: This patent, by setting up a dustproof air intake device, uses an internal fan to draw in air, which is directly blown onto the electronic components of the cabinet, thus cooling the electronic components. In addition, the dustproof air intake device is equipped with filter cotton to isolate dust in the air, thereby reducing dust inside the cabinet and keeping the machine inside clean. Furthermore, since the machine generates heat inside the cabinet, hot air rises. An exhaust vent is set at the top of the machine, which is connected to a pipe and a fan to exhaust the hot air. The incoming fresh air cools the inside of the cabinet, achieving heat exchange. Since the cabinet is placed in a computer room, which is equipped with air conditioning, the air entering through the dustproof air intake device is cool air, which is very helpful in cooling the inside of the cabinet.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 This utility model provides a cabinet ventilation device, including a chassis 1 and a door panel 2. A dustproof air inlet device 3 is provided in the middle of the door panel 2. The dustproof air inlet device 3 is fixedly connected to the door panel 2. The dustproof air inlet device 3 is provided with a detachable filter device 5.

[0015] The dustproof air intake device 3 is provided with a fan 4 and a cavity 9 on its upper and lower sides. The upper and lower ends of the cavity 9 are provided with channels that connect to the ventilation openings of the fan 4. The cavity 9 is provided with a space of a size that is compatible with the filter device 5.

[0016] The filter device 5 has an internal cavity through which filter cotton 8 is placed. One side of the filter device 5 has a protruding edge 11, which abuts against one side edge of the cavity 9.

[0017] The filter device 5 has hooks 7 on both sides of the protruding edge 11, and the cavity 9 has latches 6 on both sides of the outside. The latches 6 and hooks 7 are used to lock and unlock the filter device 5.

[0018] The fan 4 is fixed to the upper and lower sides of the dustproof air intake device 3 by screws, and the fan (4) is connected to a power cord.

[0019] It should be noted that the connection between the fan cable and the fan is an existing technology, so it is not explained in detail. Since there are many electronic components inside the chassis, there is a power interface inside. Therefore, the fan power cable can be connected to the power interface inside the chassis to provide power. In addition, the machine has an internal controller, which can be used to start or stop the fan. These are also existing technologies, so they are not explained in detail.

[0020] The upper part of the chassis 1 is provided with an exhaust port 10, which is connected to the internal space of the chassis 1. The exhaust port 10 allows the hot air inside the chassis to be exchanged.

[0021] The working principle of this patent; First, unlock the filter device 5 using the latch 6 and hook 7. Then, place the filter cotton 8 inside the filter device 5. After placing the filter cotton 8 inside the filter device 5, insert the entire filter device 5 into the cavity 9. This connects the upper and lower ends of the filter cotton to the container channel, meaning that the incoming air enters from the middle of the filter cotton and is then blown out from the upper and lower sides by the two fans 4. This way, dust in the outside air will be blocked by the filter cotton. When it needs to be replaced, simply open the latch to clean the filter cotton or replace it with a new one. This ensures a larger air intake.
