Description

Technical Field

[0001] The utility model relates to the field of motorcycle engines, in particular to a heat dissipation right cover for motorcycle engines. Background Art

[0002] When a motorcycle engine is working, the combustible mixture burns and performs work in the sealed space composed of the cylinder head combustion chamber, cylinder body and piston top, thereby achieving continuous operation of the engine. A large amount of heat energy is generated, part of which is taken away by the cylinder head and cylinder cooling fins, and part of which is dissipated by the oil flowing in the engine. The right cover of the engine, which has a chamber for placing the engine fan, can play a role in heat dissipation.

[0003] According to a Chinese patent with publication number CN210152800U, a heat dissipation right cover for a motorcycle engine is disclosed. The utility model utilizes the heat dissipation part to increase the contact area with the fan when the air is discharged, and opens a heat dissipation oil channel in the outer wall to increase the contact area with the engine oil, thereby reducing the engine oil temperature and achieving obvious heat dissipation effect.

[0004] In view of the above-mentioned disclosed patent content, a heat sink and an air outlet are provided so that heat can be dissipated through the heat sink in cooperation with the air outlet. However, the heat sink is exposed to the external environment. Over a long period of time, a large amount of dust adheres to the surface of the heat sink. If the dust accumulated on the surface of the heat sink is not cleaned in time, the dust accumulation will affect the heat dissipation effect of the heat sink, thereby reducing the overall heat dissipation efficiency of the right cover. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a heat dissipation right cover for a motorcycle engine to solve the technical problem that the heat dissipation effect of the heat sink will be affected when a lot of dust accumulates on the surface of the heat sink.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat dissipation right cover for a motorcycle engine, comprising an engine body, a right cover body being mounted on the engine body, and a volute being mounted on the outer surface of the right cover body, an air outlet and an air guide plate being respectively arranged on one side of the volute, a plurality of jet holes and a diffusion cover being respectively arranged on the back of the air guide plate, and an air guide duct being installed between the air guide plate and the air outlet.

[0007] By adopting the above technical solution, after the air and heat are discharged through the air outlet, the gas will enter the air guide duct, then enter the inside of the air guide plate, and be ejected through the jet hole and the diffusion cover.

[0008] Furthermore, a fan casing is installed on the outer surface of the volute, and a fan is arranged inside the fan casing.

[0009] By adopting the above technical solution, the air circulation speed will be accelerated when the fan is working, and the external air will enter the volute through the fan casing, and the heat in the volute can be dissipated through the air outlet.

[0010] Furthermore, a heat conducting plate is installed on the inner wall of the volute, and a plurality of heat dissipating fins extending to the outside of the volute are provided on one side of the heat conducting plate.

[0011] By adopting the above technical solution, the arrangement of the heat conducting plate and the heat sink can play a role in heat dissipation, thereby improving the heat dissipation effect on the engine.

[0012] Furthermore, a plurality of mounting holes are provided on the right cover body and the volute.

[0013] By adopting the above technical solution, the arrangement of the mounting holes facilitates the installation of the right cover body and the volute.

[0014] Furthermore, reinforcing ribs are installed inside the volute, and a protrusion is also provided inside the volute.

[0015] By adopting the above technical solution, the provision of reinforcing ribs can improve the strength of the volute, so as to improve the overall strength of the volute and the right cover body.

[0016] Furthermore, the jet hole corresponds to the diffusion cover, and the jet hole is located inside the diffusion cover.

[0017] By adopting the above technical solution, when air enters the jet hole, it will be ejected through the diffusion cover.

[0018] Furthermore, the diffusion cover and the heat sink are arranged alternately.

[0019] By adopting the above technical solution, the ejected air can flow into the gaps between the heat sinks and take away the heat dissipated by the heat sinks.

[0020] Furthermore, the heat sink is located below the air outlet, and a plurality of the heat sinks are equidistantly distributed on one side of the heat conducting plate.

[0021] By adopting the above technical solution, the heat conducting plate can conduct heat and the heat sink can dissipate heat, thereby improving the heat dissipation effect on the engine.

[0022] Furthermore, the interior of the air guide plate is hollow, and the air guide pipe is connected to the air guide plate.

[0023] By adopting the above technical solution, air can enter the interior of the air guide plate through the air guide pipe.

[0024] Furthermore, one side of the air outlet is tilted downward along the direction of the air guide plate.

[0025] By adopting the above technical solution, the air inside the volute can be discharged through the air outlet and flow downward.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] The utility model is provided with an air guide pipe, an air jet hole, an air guide plate and a diffusion cover. After the air and heat are discharged through the air outlet, the gas will enter the air guide pipe, then enter the inside of the air guide plate, and be sprayed out through the air jet hole and the diffusion cover, thereby accelerating the circulation speed of the air around the heat sink. Since the heat sink can also conduct heat, the gas sprayed through the air jet hole can take away the heat dissipated by the heat sink, avoiding the heat dissipated by the heat sink to accumulate around and be difficult to dissipate. At the same time, the sprayed gas can blow away the dust accumulated on the surface of the heat sink, preventing a large amount of dust from accumulating on the heat sink and affecting the heat dissipation efficiency of the heat sink, thereby improving the cleanliness of the surface of the heat sink and improving the heat dissipation effect of the heat sink.

When the fan 11 is working, the air circulation speed will be accelerated, and the external air will enter the volute 6 through the fan housing 10, and the heat in the volute 6 can be dissipated through the air outlet 9.

[0039] See also Figure 2-Figure 5 A heat conducting plate 7 is installed on the inner wall of the volute 6. The interior of the air guide plate 14 is hollow.

One side of the heat conducting plate 7 is provided with a plurality of heat sinks 8 extending to the outside of the volute 6. The heat sink 8 is located below the air outlet 9. A plurality of heat sinks 8 are equidistantly distributed on one side of the heat conducting plate 7. The arrangement of the heat conducting plate 7 and the heat sink 8 can play a heat dissipation role, thereby improving the heat dissipation effect of the engine. A plurality of mounting holes 4 are provided on the right cover body 2 and the volute 6. The arrangement of the mounting holes 4 facilitates the installation of the right cover body 2 and the volute 6. One side of the air outlet 9 is arranged to be tilted downward along the direction of the air guide plate 14 so that the air inside the volute 6 can be discharged through the air outlet 9 and flow downward.

[0040] See also Figure 2-Figure 7 A plurality of jet holes 13 and a diffusion cover 15 are respectively provided on the back of the air guide plate 14. An air guide pipe 12 is installed between the air guide plate 14 and the air outlet 9. When the air and heat are discharged through the air outlet 9, the gas will enter the air guide pipe 12, then enter the inside of the air guide plate 14, and be ejected through the jet holes 13 and the diffusion cover 15. The jet holes 13 correspond to the diffusion cover 15. The jet holes 13 are located inside the diffusion cover 15.
