[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] like Figures 1 to 4 As shown, this embodiment provides an engine dust removal and heat dissipation system, including a water pump 1, an engine 2 and a heat dissipation device 3. The water pump 1 is transmission-connected to the engine 2. A fan 4 and a dust removal brush 5 are provided on the rotating shaft 11 of the water pump 1. The dust removal brush 5 and the heat dissipation device 3 are located on the air outlet side of the fan 4, and the dust removal brush 5 is located between the fan 4 and the heat dissipation device 3. The fan 4 is used to cool the heat dissipation device 3, and the dust removal brush 5 is used to remove dust from the heat dissipation device 3.

[0024] The dust removal and heat dissipation system in this embodiment is achieved by arranging a fan 4 and a dust removal brush 5 on the rotating shaft 11 of the water pump 1, and arranging the dust removal brush 5 and the heat dissipation device 3 on the air outlet side of the fan 4, and arranging the dust removal brush 5 between the fan 4 and the heat dissipation device 3. The heat dissipation device 3 is cooled by the fan 4, and at the same time, the dust removal brush 5 is used to remove dust from the heat dissipation device 3, thereby effectively removing dust attached to the heat dissipation device 3 and ensuring the heat dissipation efficiency of the heat dissipation device 3.

[0025] The dust removal brush 5 in this embodiment includes a support frame 51 disposed on the rotating shaft 11 and a brush 52 disposed on the support frame 51. This embodiment utilizes the rotating shaft 11 of the water pump 1 to drive the dust removal brush 5 to rotate to remove dust from the heat dissipation device 3, which not only fully and reasonably utilizes resources but also greatly improves the dust removal efficiency.

[0026] Specifically, the support frame 51 includes a support disc 511 and a support arm 512 arranged on the circumference of the support disc 511 and extending radially along the support disc 511. The support disc 511 is fixed to the rotating shaft 11 through a locking structure, and the brush 52 is fixed to the support arm 512.

[0027] The locking structure in this embodiment includes a stud 12 arranged on the end of the rotating shaft 11 and a nut 13 threadedly connected to the stud 12. A mounting through hole 513 is provided on the support plate 511. The support plate 511 is sleeved on the stud 12 through the mounting through hole 513 and is pressed against the end of the rotating shaft 11 by the nut 13.

[0028] In order to center the stud 12 and the support plate 511, this embodiment provides a stopper structure between the stud 12 and the support plate 511. Since the stopper structure is a commonly used centering and connecting structure in the prior art, it will not be described in detail here.

[0029] In this embodiment, at least two support arms 512 are provided, and accordingly, at least two brushes 52 are provided. To improve dust removal and air cooling, this embodiment provides two support arms 512 and, accordingly, two brushes 52. In actual applications, the number of support arms 512 and brushes 52 is not limited and can be selected according to actual needs.

[0030] The fan 4 in this embodiment includes a fan connection plate 41 fixedly mounted on the rotating shaft 11, and a plurality of fan blades 42 spaced apart on the fan connection plate 41. This embodiment utilizes the rotating shaft 11 of the water pump 1 to drive the fan 4 to rotate and cool the heat sink 3, which not only fully and rationally utilizes resources but also significantly improves cooling efficiency.

[0031] In this embodiment, the water pump 1 is connected to the crankshaft of the engine 2 through a belt drive mechanism. A pulley 6 connected to the crankshaft is fixedly sleeved on the rotating shaft 11, and the fan connecting plate 41 is fixedly connected to the pulley 6 by bolts 7.

[0032] The heat dissipation device 3 in this embodiment includes a heat dissipation frame 31, an intercooler 32 and a water tank radiator 33 mounted on the heat dissipation frame 31. The water inlet of the water pump 1 is connected to the water outlet of the water tank radiator 33. The water outlet of the water pump 1 is connected to the water inlet of the engine 2 and the water inlet of the intercooler 32, respectively. The water outlet of the engine 2 and the water outlet of the intercooler 32 are respectively connected to the water inlet of the water tank radiator 33. By integrating the intercooler 32 and the water tank radiator 33, not only is space layout facilitated, but also cooling efficiency is improved.

[0033] In this embodiment, the intercooler 32 is located between the dust removal brush 5 and the water tank radiator 33. The bristles 52 of the dust removal brush 5 are in close contact with the air inlet side of the intercooler 32. The air inlet side of the intercooler 32 is also the air inlet side of the heat sink 3. Using the dust removal brush 5 to remove dust from the air inlet side of the intercooler 32 not only prevents clogging of the heat sink mesh of the intercooler 32, but also prevents dust from entering the heat sink mesh of the water tank radiator 33. This effectively removes dust from the heat sink 3 and ensures its heat dissipation efficiency.

[0034] The above is only a preferred embodiment of the engine dust removal and heat dissipation system of the present invention, and there are more embodiments that are not described here. In summary, the engine dust removal and heat dissipation system of the present invention effectively removes dust attached to the heat dissipation device 3 and ensures the heat dissipation efficiency of the heat dissipation device 3.

[0035] The present invention is not limited to the above-mentioned specific implementation methods. Various changes made by ordinary technicians in this field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.
