DETAILED DESCRIPTION

[0023] The high-efficiency direct-current variable-frequency air-cooled module unit with good noise reduction effect is described in detail in combination with the drawings and specific embodiments; meanwhile, it is explained here that, in order to make the embodiments more detailed, the following embodiments are preferred embodiments, and for some known technologies, other alternative ways can also be adopted by the person skilled in the art.

[0024] For example, Figures 1 to 4The utility model discloses an embodiment provides a high -efficient direct current frequency conversion air -cooled module unit with good noise reduction effect, including main body 1, the one side fixed intercommunication of main body 1 has the air inlet pipe 2, the inboard fixed connection of air inlet pipe 2 has fixed seat 3, the inboard rotation connection of fixed seat 3 has the rotation bar, and the rotation bar side fixed connection of far away main body 1 has the toothed disc 4, and the inboard fixed connection of air inlet pipe 2 far away main body 1 has the silencer pipe 8, and the inboard fixed connection of silencer pipe 8 has a plurality of flow -coils 11, and the number of flow -coils 11 is three, and the diameter of flow -coils 11 inboard gradually reduces towards the end of air inlet pipe 2, and the flow -coil 11 of middle is opposite to the other two flow -coils 11, and the inside fixed connection of main body 1 has the heat sink 12, and the inside fixed connection of main body 1 is located the heat sink 12 near air inlet pipe 2 one side and has the fan 13, and the side of main body 1 far away air inlet pipe 2 is set up with a plurality of air outlet holes 14.

[0025] Start fan 13, inhale air through silencer pipe 8, after air enters silencer pipe 8, through the arc reduction structure of multiple flow -coils 11 and the irregular cavity inboard, change the flow direction and speed of airflow, make airflow form multiple reflection and interference in silencer pipe 8, to reach the effect of noise reduction, and then air enters air inlet pipe 2.

[0026] Three flow -coils 11 adopt staggered design, and they are staggered according to certain angle and distance, when air enters silencer pipe 8, first meets the first flow -coil 11, this flow -coil 11 will immediately change the direction of air flow, so that it no longer maintains the original straight trajectory, then, air will flow through the second and third flow -coils 11, and the two flow -coils 11 further guide and disperse air, so that the flow of air becomes more complex and changeable, not only changes the direction of air, but also significantly affects its speed, also makes the irregular cavities in silencer pipe 8, these cavities will absorb the kinetic energy of air when it flows, further reduce the flow rate and energy of air, when the energy of air is fully absorbed, it is not easy to emit larger noise when flowing, to realize the purpose of noise reduction.

[0027] As Figures 1 to 4As shown, the inside of the air inlet pipe 2 is fixedly connected with a filter plate 7 at one end close to the main body 1 of the cleaning brush 5, and a driving assembly 6 is connected with the air inlet pipe 2, the driving assembly 6 is used to drive the gear disc 4, the number of the driving assembly 6 is two, which are respectively located at both ends of the inside of the air inlet pipe 2, and the two driving assemblies 6 are opposite in direction, the driving assembly 6 comprises a driving shaft 601 rotatably connected to the inside of the air inlet pipe 2, a mounting sleeve 602 is fixedly connected to the outside of the driving shaft 601, a plurality of wind receiving strips 603 are fixedly connected to the outside of the mounting sleeve 602, a driving gear 604 is fixedly connected to the side of the driving shaft 601 away from the air inlet pipe 2, the top end of the wind receiving strip 603 is a semicircular concave structure, a wind receiving hole 9 is formed at both ends of the outside of the air inlet pipe 2, one of the wind receiving holes 9 is flush with the top end of the corresponding wind receiving strip 603, and the other wind receiving hole 9 is flush with the low end of the corresponding wind receiving strip 603, the two driving gears 604 are engaged with the two sides of the gear disc 4 at right angles, a collecting groove is formed in the bottom of the filter plate 7 in the air inlet pipe 2, and a collecting box 10 is slidably connected in the collecting groove.

[0028] Then the air passes through the filter plate 7, enters the inside of the main body 1, and then passes through the heat sink 12 to remove the heat in the air, and then is discharged through the air outlet hole 14. When the air enters the muffler pipe 8, the air also enters the air inlet pipe 2 through the wind receiving hole 9. When the air enters, it will impact on the wind receiving strip 603. Since the top end of the wind receiving strip 603 is a semicircular concave structure, the air flow will generate a pushing force, so that the driving shaft 601 starts to rotate. When the driving shaft 601 rotates, the driving gear 604 is engaged with the gear disc 4 at right angles, so as to drive the rotating rod and the cleaning brush 5 to rotate. The cleaning brush 5 will continuously clean the surface of the filter plate 7 in the rotating process, and the dust and impurities cleaned will fall into the collecting box 10, which is convenient for subsequent cleaning and processing.

[0029] When the fan 13 is started, a strong suction force is formed at the wind receiving hole 9. This suction force makes the external air be quickly sucked in, so as to form a negative pressure area around the wind receiving hole 9. The semicircular concave structure design of the wind receiving strip 603 makes the air flow be maximized to be converted into the power of the rotation of the driving shaft 601. Then, through the cooperation of the driving gear 604 and the gear disc 4, the rotating power of the cleaning brush 5 is given, so as to effectively remove the dust and impurities accumulated on the filter plate 7. Not only the cleaning efficiency of the filter plate 7 is greatly improved, but also the way of cleaning by additional equipment is completely abandoned, so as to significantly reduce the production cost and use cost of the device.

[0030] The utility model provides a working principle: start fan 13, inhale air through silencer pipe 8, after air enters silencer pipe 8, through the arc reducing structure of multiple flow guide rings 11 and its inside irregular cavity, change the flow direction and speed of airflow, make airflow form multiple reflection and interference in silencer pipe 8, thereby reach the effect of noise reduction, and then air enters air inlet pipe 2, and then air passes through filter plate 7, enters the inside of main part 1, removes the heat in air again through heat dissipation plate 12, and then is discharged through air outlet hole 14, when air enters silencer pipe 8, air will also enter air inlet pipe 2 through wind receiving hole 9, when air enters, will impact on wind receiving strip 603, because the top of wind receiving strip 603 is semicircular concave structure, air flow will produce propelling force, make drive shaft 601 start rotating, when drive shaft 601 rotates, through the right angle engagement of drive gear 604 and toothed disc 4, drive rotating rod and cleaning brush 5, cleaning brush 5 will constantly clean the surface of filter plate 7 in the rotating process, and the dust and impurities cleaned down will fall into collecting box 10, make subsequent cleaning and processing convenient.
