Description

Technical Field

[0001] This utility model belongs to the field of computer cooling technology, specifically relating to a computer cooling device. Background Technology

[0002] Currently, computers are becoming increasingly common and are used in various industries. They have become essential office equipment, and people use them for long periods of time every day. However, after a period of use, the components inside the computer case will generate heat, causing the temperature inside the case to rise, which in turn affects the computer's operating speed.

[0003] Currently, computer mainframes primarily rely on fans for heat dissipation. In humid environments, such as those caused by rain, moist air can enter the mainframe through the fan. This humid air can cause various forms of damage to internal components. Firstly, when there is a significant temperature difference between the inside and outside of the mainframe, the humid air may condense into tiny water droplets on the surfaces of colder components, leading to short circuits and severely affecting the normal operation of delicate components such as the motherboard, CPU, and graphics card, even causing permanent damage. Secondly, a humid environment accelerates the oxidation of internal metal components (such as screws, heatsinks, and interface pins), reducing heat dissipation efficiency and causing problems such as startup failures or abnormal data transmission. Furthermore, humid air can cause dust particles to adhere to the surfaces of components, forming a "wet dust" mixture that clogs fan blades and ventilation holes, further reducing heat dissipation.

[0004] Existing computer host cooling devices lack effective moisture-proof measures and cannot provide good protection for internal components in humid environments. Therefore, there is an urgent need to design a computer host moisture-proof cooling device that can solve the above problems. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a computer cooling device, which aims to solve the problem that the existing computer host heat dissipation device lacks effective moisture-proof measures and cannot provide good protection for internal components in a humid environment.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a computer cooling device, including a computer casing, a rear cover at the rear end of the computer casing, a handle fixedly connected to the upper front end of the computer casing, a cooling mechanism connected inside the computer casing, and the cooling mechanism including a fixing plate fixedly connected to the right end of the inner side of the computer casing, a fan installed on the upper right end of the inner side of the rear cover, an air intake fixedly connected to the front side of the rear cover at the position of the fan, a first filter screen provided at the lower front end of the fixing plate, a second filter screen fixedly connected to the upper front end of the computer casing, and a replacement unit provided at the rear end of the computer casing.

[0009] Furthermore, the replacement unit includes a first bolt connected to the four corners inside the rear cover, a rectangular frame fixedly connected to the outer perimeter of the first filter screen, and a second bolt connected to the four corners inside the rectangular frame.

[0010] Furthermore, the fixed plate has a flow channel inside, with the inlet of the flow channel located above the rear end of the fixed plate and the outlet of the flow channel located below the rear end of the fixed plate. The flow channel is filled with activated carbon particles.

[0011] Furthermore, the flow channels inside the fixed plate are S-shaped bends.

[0012] Furthermore, the front side of the air intake hopper abuts against the flow channel inlet on the rear side of the fixed plate.

[0013] Furthermore, the back cover has round holes at the four inner corners, and the computer casing has first threaded grooves at the four rear corners. The outer side of the first bolt is slidably connected to the inner side of the round hole, and the outer side of the first bolt is threadedly connected to the inner side of the first threaded groove.

[0014] Furthermore, sliding holes are provided at the four corners of the rectangular frame, and second threaded grooves are provided at the upper left and lower right ends of the flow channel outlet at the rear end of the fixed plate. The outer side of the second bolt is slidably connected to the inner side of the sliding hole, and the outer side of the second bolt is threadedly connected to the inner side of the second threaded groove.

[0015] Furthermore, a rubber pad is affixed to the front side of the rectangular frame.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention incorporates a cooling mechanism. After the rear cover is installed at the rear of the computer casing, the front of the air intake hopper contacts the inlet of the flow channel on the rear side of the fixing plate. Then, the fan is activated to allow airflow into the air intake hopper. The airflow then enters the flow channel from the front of the air intake hopper. During the flow process within the flow channel, moisture in the air is adsorbed by activated carbon particles in the flow channel, thus drying the air. Furthermore, the activated carbon particles in the flow channel and the first filter at the flow channel outlet filter dust in the air. This ensures that the air discharged from the flow channel into the computer casing is dehumidified and dust-free, preventing damage to the internal components of the computer casing.

[0019] This invention, by setting up a replacement unit, allows activated carbon particles in the flow channel to slide down the inner side of the flow channel and finally flow out from the outlet when the drying effect of the activated carbon particles in the flow channel is poor due to long-term use. After removing the back cover and then removing the second bolt from the second threaded groove, the activated carbon particles in the flow channel can be replaced. Then, after reinstalling the rectangular frame and the first filter screen, new activated carbon particles can be put in through the inlet above the rear end of the fixed plate. This completes the replacement of activated carbon particles in the flow channel inside the fixed plate and maintains the dehumidification effect of the cooling device. Attached Figure Description

[0027] 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.

[0028] This specific embodiment is a computer cooling device, and its structural schematic diagram is shown below. Figures 1 to 4 As shown, the computer includes a computer casing 1, a rear cover 2 at the rear end of the computer casing 1, and a handle 3 fixedly connected to the upper front end of the computer casing 1. A cooling mechanism is connected inside the computer casing 1, and the cooling mechanism includes a fixing plate 401 fixedly connected to the right side of the inner side of the computer casing 1. The fixing plate 401 has an internal flow channel, with the inlet located above the rear end of the fixing plate 401 and the outlet located below the rear end of the fixing plate 401. The flow channel is filled with activated carbon particles. The flow channel inside the fixing plate 401 is S-shaped. This S-shaped flow channel increases the airflow path within the pipe, thereby increasing the contact time between the external air and the activated carbon before it enters the computer casing 1, ensuring effective dehumidification of the air entering the computer casing 1.

[0029] Among them, a fan 402 is installed on the upper right side of the interior of the back cover 2, an air intake 403 is fixedly connected to the front side of the back cover 2 at the position of the fan 402, a first filter 404 is provided on the lower front side of the fixing plate 401, a second filter 405 is fixedly connected to the upper front of the computer shell 1, and the front side of the air intake 403 abuts against the flow channel inlet on the rear side of the fixing plate 401. After the rear cover 2 is installed on the rear end of the computer casing 1, the front side of the air intake 403 will contact the inlet of the airflow channel on the rear side of the fixing plate 401. Then, the fan 402 is turned on to allow airflow into the air intake 403. The airflow will then enter the airflow channel from the front end of the air intake 403. During the flow in the airflow channel, the moisture in the air will be adsorbed by the activated carbon particles in the airflow channel to dry the air. The activated carbon particles in the airflow channel and the first filter 404 at the outlet of the airflow channel will filter the dust in the air, so that the air discharged from the airflow channel into the computer casing 1 will be dehumidified and dust removed. When the air enters the computer casing 1, the air inside the computer casing 1 will be discharged from the second filter 405 to dissipate heat and cool the inside of the computer casing 1.

[0030] Cooperate Figure 5As shown, a replacement unit is provided at the rear end of the computer casing 1. The replacement unit includes first bolts 501 connected to the four corners inside the rear cover 2. Circular holes are provided at the four corners inside the rear cover 2, and first threaded grooves are provided at the four corners at the rear end of the computer casing 1. The outer side of the first bolts 501 is slidably connected to the inner side of the circular holes, and the outer side of the first bolts 501 is threadedly connected to the inner side of the first threaded grooves. Therefore, after placing the rear cover 2 at the rear end of the computer casing 1, the first bolts 501 are passed through the circular holes inside the rear cover 2 and then threaded into the first threaded grooves, thus fixing the rear cover 2 to the rear end of the computer casing 1.

[0031] The first filter screen 404 is fixedly connected to a rectangular frame 502 around its outer perimeter. Second bolts 503 are connected to the four corners of the rectangular frame 502. Sliding holes are provided at the four corners of the rectangular frame 502. Second threaded grooves are provided at the upper left and lower right ends of the flow channel outlet at the rear end of the fixed plate 401. The outer side of the second bolt 503 is slidably connected to the inner side of the sliding hole, and the outer side of the second bolt 503 is threadedly connected to the inner side of the second threaded groove. Therefore, when the activated carbon particles in the flow channel become less effective due to prolonged use, by removing the rear cover 2 and then removing the second bolts 503 from the second threaded grooves, the activated carbon particles in the flow channel can slide down the inner side of the flow channel and finally flow out from the outlet. After reinstalling the rectangular frame 502 and the first filter screen 404, new activated carbon particles are inserted through the inlet above the rear end of the fixed plate 401, thus replacing the activated carbon particles in the flow channel inside the fixed plate 401 and maintaining the dehumidification effect of the cooling device.

[0032] In addition, a rubber pad is attached to the front side of the rectangular frame 502. Therefore, when the first filter screen 404 and the rectangular frame 502 are installed at the outlet of the flow channel on the rear side of the fixing plate 401, the rubber pad on the front side of the rectangular frame 502 will contact the rear side of the fixing plate 401, thus maintaining a seal between the rear side of the fixing plate 401 and the rectangular frame 502, preventing activated carbon fragments in the flow channel from falling out between the fixing plate 401 and the rectangular frame 502.

[0033] Working principle: When cooling the computer casing 1 during operation, the fan 402 is turned on, allowing airflow into the air intake 403. The airflow then enters the flow channel from the front end of the air intake 403. During the flow in the flow channel, the moisture in the air is adsorbed by the activated carbon particles in the flow channel, drying the air. The activated carbon particles in the flow channel and the first filter 404 at the flow channel outlet filter the dust in the air, performing dust removal and dehumidification treatment before being discharged into the computer casing 1. When the air enters the computer casing 1, the air inside the computer casing 1 is discharged through the second filter 405, dissipating heat and cooling the inside of the computer casing 1.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
