DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-3The heat dissipation fan shown in the figure is easy to install, including a shell 1, a fixing plate 2 is arranged at the four corners of the upper and lower outer walls of the shell 1, a through hole 5 is arranged inside the center of the front outer wall of the shell 1, and a blocking device 8 is arranged on the front and rear outer walls of the shell 1. The blocking device 8 includes a slide groove 10, a slide rail 11, a dustproof net 12 and a frame 13. The front and rear outer walls of the shell 1 are respectively provided with slide rails 11 near the left and right sides, and the slide grooves 10 are arranged inside the center of the left and right outer walls of the multiple slide rails 11. 0, and a dustproof net 12 is arranged inside the center of the two frames 13. First, the frame 13 is inserted into the slide groove 10. When the dust on the dustproof net 12 at the center of the frame 13 accumulates to a certain thickness, the frame 13 is lifted up and taken out, and then the dustproof net 12 in the frame 13 is placed in water for cleaning. When the dust on the dustproof net 12 is cleaned, the water on the dustproof net 12 is shaken off, and after the water is completely dry, it is reinserted into the slide groove 10 for continued use.

[0022] like Figure 3 As shown, sound absorbing devices 9 are arranged on the upper, lower, left and right outer walls of the shell 1, and the sound absorbing devices 9 include an adhesive plate 14, sound absorbing holes 15, a sound absorbing plate 16 and a reflecting plate 17. An adhesive plate 14 is arranged at the center of the right end outer wall of the shell 1, and a sound absorbing plate 16 is arranged on the right end outer wall of the adhesive plate 14. A plurality of sound absorbing holes 15 are arranged inside the right end outer walls of the adhesive plate 14 and the sound absorbing plate 16, and a reflecting plate 17 is arranged on the right end outer wall of the sound absorbing plate 16. When the sound waves emitted from the inside of the shell 1 pass through the sound absorbing holes 15 at the upper ends of the adhesive plate 14 and the sound absorbing plate 16, most of the sound waves will be absorbed by the sound absorbing holes 15, and part of the sound waves will be buffered and reduced in the gaps of the sound absorbing plate 16. The sound waves that are not completely absorbed will be reflected to the sound absorbing plate 16 and the sound absorbing holes 15 in the adhesive plate 14 when they contact the reflecting plate 17 for secondary absorption.

[0023] like Figure 1 As shown, connecting rods 6 are arranged at the four corners of the circular inner wall of the through opening 5 and near the front and rear sides respectively, which can fix the connecting shaft 4 so that the connecting shaft 4 can be located in the center of the through opening 5, and a connecting shaft 4 is arranged between multiple connecting rods 6 to fix the rotating shaft 7. A rotating shaft 7 is arranged between two connecting shafts 4 to drive the fan blades 3 to rotate, and a plurality of fan blades 3 are equidistantly arranged at the center of the circular outer wall at the upper end of the rotating shaft 7. When driven to rotate by the rotating shaft 7, the wind at one end can be transmitted to the other end.

[0024] like Figure 2As shown, the outer walls of the frame 13 and the inner walls of the chute 10 are respectively fitted together, and there will not be much resistance when the frame 13 slides inside the chute 10. The frame 13 can slide up and down inside the chute 10, so that the dustproof net 12 at the center of the frame 13 can be taken out for cleaning and reuse when it is full of dust. The dustproof net 12 is made of stainless steel material and has the ability to resist rust corrosion. It will not easily rust after multiple water washings. The dustproof net 12 and the frame 13 are fixedly connected by welding, so that when the dust on the dustproof net 12 is washed with water, the dustproof net 12 and the frame 13 will not be separated due to the unstable connection between the dustproof net 12 and the frame 13.

[0025] like Figure 3 As shown, the sound absorbing plate 16 is made of sponge latex material, and the interior of the sponge latex material has a plurality of tiny holes, which can continuously attenuate the sound waves in the tiny holes. The reflecting plate 17 is made of polyethylene plastic material, and can radiate the sound waves transmitted by the sound absorbing plate 16, so that the sound waves can be reduced for a second time. The adhesive plate 14 and the outer shell 1 are fixedly connected by an adhesive, so that the connection between the adhesive plate 14 and the outer shell 1 is more stable and not easy to fall off. The sound absorbing holes 15 on the adhesive plate 14 and the sound absorbing plate 16 are aligned with each other, so that when the sound waves are transmitted from the sound absorbing holes 15 on the adhesive plate 14 and the sound absorbing plate 16, the adhesive plate 14 and the sound absorbing plate 16 can generate the same frequency to eliminate the sound waves.

[0026] The working principle of the utility model is as follows: first, it is detected whether the rotating shaft 7 in the through port 5 can rotate normally. If it cannot rotate normally, the rotating shaft 7 that can rotate is replaced in time. Then, the fixing plate 2 is respectively fixedly connected to the machines that need heat dissipation through locking screws. Then, the rotating shaft 7 is connected to the external power supply. After power is turned on, the electricity drives the fan blades 3 on the rotating shaft 7 to rotate clockwise. The wind pressure generated during rotation will blow the hot air inside the machine to the outside of the machine under the action of the wind pressure, thereby achieving the transfer of hot air inside the machine, avoiding the problem of high temperature of the machine caused by accumulation inside the machine, resulting in reduced work efficiency. When the power supply is stopped, the fan blades 3 on the rotating shaft 7 will slowly reduce the speed until it stops, and will continue to rotate when the power is turned on next time.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
