[0030] 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.

[0031] Reference Figure 1 The utility model provides an embodiment: an economical fan controller, including a controller body 1, the controller body 1 includes a PCB mainboard and a plastic shell, a lower cover, and an upper cover, wherein the PCB mainboard and the plastic shell are partially welded and then assembled with the lower cover and the upper cover, a heat conducting plate 3 is fixedly connected to the bottom of the controller body 1, and the heat conducting plate 3 is provided in multiple groups and is wavy in shape, so as to improve the heat conduction effect of the controller body 1, and the heat generated on the controller body 1 can be conducted to the shell 21 through the heat conducting plate 3, and a heat dissipation component 2 is provided at the bottom of the heat conducting plate 3, and the heat dissipation effect of the controller body 1 is improved through the heat dissipation component 2.

[0032] Reference Figure 3The heat dissipation component 2 includes a shell 21, through which the heat transferred by the heat conducting plate 3 is dispersed, so as to improve the heat dissipation effect of the controller body 1. An exhaust fan 23 is fixedly connected to the left side of the shell 21. The exhaust fan 23 and the air outlet fan 22 are both micro devices. The outside air is extracted into the shunt pipe 24 through the exhaust fan 23. The right end of the exhaust fan 23 is fixedly connected to the shunt pipe 24. The air extracted by the exhaust fan 23 is transported to two groups of connecting pipes 25 through the shunt pipe 24. The right side of the shunt pipe 24 is fixedly connected to the connecting pipe 25. The right side of the shunt pipe 24 is fixedly connected to the air outlet fan 22. The hot air in the shell 21 is discharged out of the shell 21 through the air outlet fan 22. The air inlet and outlet efficiency in the shell 21 is improved by the exhaust fan 23 and the air outlet fan 22. A limiting component 29 is arranged on the front side of the shell 21. The limiting component 29 facilitates the installation or removal of the shell 21, so that the heat dissipation component 2 can be installed according to the needs of the user, and the economy of the fan and the controller body 1 is improved.

[0033] Reference Figure 1 and Figure 2 The controller body 1 is made of polypropylene material. Polypropylene is a lightweight, corrosion-resistant plastic with good formability and durability. It can be recycled to reduce resource waste. The heat conducting plate 3 is made of aluminum alloy material. Aluminum alloy material has excellent thermal conductivity and is a common heat dissipation material. It is relatively light, easy to process, and relatively economical.

[0034] Reference Figure 2 and Figure 5 The limiting assembly 29 includes a mounting block 291, and the mounting blocks 291 are symmetrically and staggeredly distributed in two groups. The inner wall of the top right side of the mounting block 291 is elastically connected with a wedge block 292 through a spring 293. Through the elastic force of the spring 293, the wedge block 292 always maintains a snap-fit ​​effect with the buckle 294 when not affected by external force, and the mounting block 291 is limited so that the shell 21 remains fixed. The front side of the controller body 1 is fixedly connected with a buckle 294, and the buckle 294 is symmetrically and staggeredly distributed in two groups.

[0035] Reference Figure 3 and Figure 4 A fixing frame 26 is fixedly connected to the bottom of the inner wall of the shell 21, and the fixing frame 26 is distributed in multiple groups in an array. The fixing effect of the fixing frame 26 can prevent the fan of the fixing frame 26 from falling off. The outer wall of the fixing frame 26 is rotatably connected to a sleeve 27. The square plate 28 can rotate through the rotation effect of the sleeve 27. The outer wall of the sleeve 27 is fixedly connected to the square plate 28. The square plates 28 are distributed in multiple groups in a circular array. The wind force discharged through the connecting pipe 25 can blow multiple groups of square plates 28 to rotate, thereby dispersing the wind force.

[0036] Reference Figure 1 and Figure 3The top of the shell 21 contacts the bottom of the heat conducting plate 3. A through hole is provided on the front of the connecting pipe 25. There are multiple groups of through holes. The air in the connecting pipe 25 is discharged into the shell 21 through the multiple groups of through holes. Two groups of connecting pipes 25 are provided. The two groups of connecting pipes 25 are symmetrically distributed along the center line of the shell 21. By providing two groups of connecting pipes 25, the incoming air convects up and down, so that the gas forms a circulation flow inside the shell 21, thereby improving the heat dissipation effect.

[0037] Reference Figure 5 The bottom end of the back side of the mounting block 291 is fixedly connected to the left end of the front side of the shell 21. The fixing effect of the mounting block 291 prevents the mounting block 291 from falling off. One end of the spring 293 is fixedly connected to the top right side of the mounting block 291. The other end of the spring 293 is fixedly connected to the outer wall of the wedge block 292. The fixing effect of the spring 293 keeps the wedge block 292 fixed to prevent the wedge block 292 from falling off.

[0038] Reference Figure 5 The outer wall of the wedge block 292 is slidably connected to the right inner wall of the mounting block 291. Through the sliding effect of the wedge block 292, the wedge block 292 and the buckle 294 are engaged or released. The outer wall of the wedge block 292 is engaged with the inner wall of the buckle 294. Through the engaging effect of the wedge block 292 and the buckle 294, the controller body 1 limits the mounting block 291.

[0039] Working principle: When it is necessary to improve the heat dissipation effect of the controller body 1, the staff will plug and install the mounting block 291 and the buckle 294, so that the wedge block 292 is clamped with the inner wall of the buckle 294 under the elastic force of the spring 293, and the mounting block 291 is limited at the same time, so that the shell 21 remains fixed, and the top of the shell 21 contacts the bottom of the heat conduction plate 3.

[0040] When the controller body 1 generates heat during operation, the heat is transferred to the shell 21 through the heat conduction plate 3. By starting the exhaust fan 23 and the exhaust fan 22, the exhaust fan 23 draws external air into the shunt pipe 24, and the air is transported to the two groups of connecting pipes 25 through the shunt pipe 24. Through the multiple groups of through holes opened on the connecting pipes 25, the air discharged from the two groups of connecting pipes 25 forms front-to-back convection, so that the gas forms a circulation flow inside the shell 21, thereby improving the heat dissipation effect of the control box. At the same time, the exhausted air blows the multiple groups of square plates 28, so that the multiple groups of square plates 28 rotate, further disperse the wind force, ensure the uniformity of heat dissipation, and discharge the hot air in the shell 21 through the exhaust fan 22, accelerate the air inlet and outlet efficiency in the shell 21, thereby improving the heat dissipation effect of the controller body 1.

[0041] When the user needs to consider economy and does not use the heat dissipation assembly 2, the staff presses the wedge block 292 so that the wedge block 292 releases the clamping effect with the buckle 294 and releases the limiting effect on the mounting block 291, thereby releasing the fixing effect on the shell 21, making it easier for the staff to remove the shell 21, thereby completing the disassembly of the shell 21.

[0042] 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.
