DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-4 , the present utility model provides a technical solution: a computer chassis with an active heat dissipation function, including:

[0028] a chassis body 1 with a ventilation net, and a cooling frame 2 fixedly installed on the top of the chassis body 1;

[0029] An exhaust pipe 3 is connected to the bottom of the cooling frame 2, and the lower end of the exhaust pipe 3 penetrates through the top of the inner wall of the chassis body 1 and extends;

[0030] A cooling component 4 is installed inside the cooling frame 2;

[0031] A cleaning component 5 is arranged inside the chassis body 1 for dust removal of the ventilation meshes on both sides;

[0032] The cooling component 4 includes a semiconductor refrigerator 41 embedded in the top of the cooling frame 2. The refrigerating surface at the bottom of the semiconductor refrigerator 41 is located inside the cooling frame 2. A curved pipe 42 is fixedly installed inside the cooling frame 2. One end of the curved pipe 42 is connected to the top of the exhaust pipe 3, and one end of the curved pipe 42 away from the exhaust pipe 3 on the surface is communicated with a fan device 43.

[0033] A solenoid valve 6 is installed on the surface of the exhaust pipe 3, and a plurality of ventilation holes 7 are opened on one side of the exhaust pipe 3;

[0034] In this embodiment, when the temperature sensor 8 detects that the temperature inside the chassis body 1 rises, the semiconductor refrigeration sheet is started to cool the inside of the cooling frame 2. Among them, the curved pipe 42 inside the cooling frame 2 will have its internal air temperature reduced. By starting the fan device 43, external air is inhaled into the curved pipe 42 for cooling. Among them, the travel of the external air entering the curved pipe 42 is relatively long, and the effect of turning the external hot air into cold air is better. The solenoid valve 6 is opened, and the cooled air enters the exhaust pipe 3 and is discharged into the chassis body 1.

[0035] A temperature sensor 8 is installed on the inner wall of the chassis body 1, and a controller 9 electrically connected to the temperature sensor 8 and the solenoid valve 6 is installed on one side of the cooling frame 2;

[0036] It should be noted that the temperature sensor 8 is responsible for converting the temperature information in the chassis body 1 into an electrical signal for the controller 9 to read. The controller 9 is the "decision-making mechanism". It receives the electrical signal from the temperature sensor 8 and judges whether it is necessary to adjust the ambient temperature according to the preset parameters. The controller 9 needs to establish connections with the temperature sensor 8 and the solenoid valve 6. First, connect the output end of the temperature sensor 8 to the input end of the controller 9; then, connect the output end of the controller 9 to the control end of the solenoid valve 6. During the configuration process, it is necessary to set the upper and lower temperature limits and the output linkage function corresponding to the solenoid valve 6 according to the actual requirements.

[0037] An assembly seat 10 is fixedly installed on the surface of the exhaust pipe 3, and one side of the assembly seat 10 is fixedly installed on the inner wall of the chassis body 1 through bolts;

[0038] Specifically, an assembly seat 10 is installed on the surface of the exhaust pipe 3 to strengthen the fixation effect on the exhaust pipe 3.

[0039] The cleaning member 5 includes two threaded rods 51 rotatably installed inside the chassis body 1. The lower ends of the two threaded rods 51 are rotatably installed at the short plates on the inner wall of the chassis body 1. Cleaning brush plates 52 are threadedly installed on the surfaces of the two threaded rods 51. The brush part on one side of the cleaning brush plate 52 is in contact with the ventilation net. A driving member 50 for rotating the two threaded rods 51 is installed on the top of the chassis body 1;

[0040] It should be noted that the driving member 50 can drive the two threaded rods 51 to rotate. The cleaning brush plates 52 are threadedly installed on the surfaces of the threaded rods 51, and the brush part on the surface of the cleaning brush plates 52 is in contact with the ventilation net, so as to scrape the dust on the ventilation net and prevent the ventilation net from being blocked by dust, affecting the heat dissipation effect.

[0041] The driving member 50 includes a motor 501 fixedly installed on the top of the chassis body 1. The output end of the motor 501 penetrates the inner wall of the chassis body 1 and is equipped with a driving wheel 502. Driven wheels 503 are fixedly installed on the surfaces of the two threaded rods 51, and the driving wheel 502 is connected to the two driven wheels 503 through a toothed belt 504;

[0042] Furthermore, starting the motor 501 drives the driving wheel 502 at its output end to rotate. The driving wheel 502 is meshed and connected to the two driven wheels 503 through the toothed belt 504, and the rotation of the driving wheel 502 drives the toothed belt 504 and the two driven wheels 503 to rotate.

[0043] Slots 11 are opened on both sides of the inner wall of the chassis body 1. Insert bars 12 are slidably installed inside the two slots 11. A dust box 13 is fixedly installed on one side of the insert bar 12;

[0044] Among them, the dust on the ventilation net falls into the dust box 13. The cooperation of the slots 11 and the insert bars 12 is used to facilitate the loading and unloading operation of the dust box 13.

[0045] The curved pipe 42 is made of copper pipe. The copper pipe has strong corrosion resistance, can maintain the stability of the material in a complex and changeable working environment, is not easy to rust and grow bacteria, thus extending the service life of the cooling member 4.

[0046] When the temperature sensor 8 of this device detects that the temperature inside the chassis body 1 rises, the semiconductor refrigerating sheet is started to cool the inside of the cooling frame 2. Among them, the temperature of the curved pipe 42 inside the cooling frame 2 and the air inside it will decrease. By starting the fan 43, external air is inhaled into the curved pipe 42 for cooling. Among them, the travel of the external air entering the curved pipe 42 is relatively long, and the effect of changing the external hot air into cold air is better. The solenoid valve 6 is opened, and the cooled air enters the exhaust pipe 3 and is discharged into the chassis body 1.

[0047] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
