Abstract
The utility model relates to a heat dissipation type motorcycle engine cylinder body, including piston room, cylinder inner wall and chain room, the cylinder inner wall is located between piston room and the chain room, and the periphery of piston room is protruding to be equipped with a plurality of first fin, has all opened the through -hole on every first fin, and the through -hole on a plurality of first fin constitutes helical structure on the space, and the equal circumference equipartition of both sides face of a plurality of first fin has a plurality of second fin, and the length direction of a plurality of second fin is coincident with the radial direction of first fin. The utility model discloses use more fin to increase heat radiating area under the condition of affect using not, including be helical structure's through -hole on the space, make a plurality of first fin intercommunication, increased gaseous circulation, make the heat dissipation of cylinder body quicker, the strong has avoided because the overheated affect using scheduling problem that causes of cylinder body.
Description
Technical field
The utility model relates to cylinder block technical field, especially relates to a kind of heat radiating type motorcycle engine cylinder block.
Background technique
General speed gram reaches refining formula engine in four-journey that locomotive (SCOOTER-TYPEMOTORCYCLE) uses, is through air inlet that cylinder internal goes round and begins again, compression, blast, the four-journey of exhaust and the power produced continuously.Wherein, the piston chamber of cylinder block inside, because the high speed to-and-fro motion of piston, the high heat of inevasible generation.Therefore, some radiating fin are convexly equipped with to increase heat diffusion area in the periphery of the piston chamber of cylinder block, utilize forced air-cooled mode, outside is dissipated to the smooth high temperature born by cylinder wall, avoid engine operating temperature too high and affect performance, but due to the temperature of cylinder block higher, the less requirement that can't meet quick heat radiating of the radiating fin on cylinder block.
Model utility content
The technical problems to be solved in the utility model is: higher in order to overcome the temperature of cylinder block in prior art, and the less problem that can not meet quick heat radiating of the radiating fin on cylinder block provides a kind of heat radiating type motorcycle engine cylinder block.
The utility model solves the technological scheme that its technical problem adopts: a kind of heat radiating type motorcycle engine cylinder block, comprise piston chamber, cylinder inner wall and chain chamber, described cylinder inner wall is between piston chamber and chain chamber, the periphery of described piston chamber is convexly equipped with some first radiating fin, each described first radiating fin all has through hole, through hole on some first radiating fin spatially forms helix structure, the bi-side of some described first radiating fin are all evenly distributed in some second radiating fin, the length direction of some described second radiating fin overlaps with the radial direction of the first radiating fin.
Further, described second radiating fin is plate radiating plate.
In order to increase heat diffusion area when not affecting use, described second radiating fin is wave shaped radiator.
The utility model uses more radiating fin to add heat diffusion area when not affecting use, add the through hole of spatially helically structure, some first radiating fin are communicated with, add the circulation of gas, the heat radiation making cylinder block is quicker, strong avoid cause because cylinder block is overheated affect the problems such as use.
The beneficial effects of the utility model are: the utility model uses more radiating fin to add heat diffusion area when not affecting use, add the through hole of spatially helically structure, some first radiating fin are communicated with, add the circulation of gas, the heat radiation making cylinder block is quicker, strong avoid cause because cylinder block is overheated affect the problems such as use.
Accompanying drawing explanation

Fig. 2 is the left view of embodiment 1 in the utility model;
Fig. 3 is the plan view of embodiment 2 in the utility model;
Fig. 4 is the left view of embodiment 2 in the utility model.
In figure: 1. piston chamber, 2. cylinder inner wall, 3. chain chamber, 4. the first radiating fin, 5. the second radiating fin, 6. through hole.
Embodiment
The utility model is described in more detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Embodiment 1:
A kind of heat radiating type motorcycle engine cylinder block as illustrated in fig. 1 and 2, comprise piston chamber 1, cylinder inner wall 2 and chain chamber 3, cylinder inner wall 2 is between piston chamber 1 and chain chamber 3, the periphery of piston chamber 1 is convexly equipped with some first radiating fin 4, each first radiating fin 4 all has through hole 6, through hole 6 on some first radiating fin 4 spatially forms helix structure, the bi-side of some first radiating fin 4 are all evenly distributed in some flat second radiating fin, and the length direction of some second radiating fin 5 overlaps with the radial direction of the first radiating fin 4.
The utility model uses more radiating fin to add heat diffusion area when not affecting use, add the through hole 6 of spatially helically structure, some first radiating fin 4 are communicated with, add the circulation of gas, the heat radiation making cylinder block is quicker, strong avoid cause because cylinder block is overheated affect the problems such as use.
Embodiment 2:
A kind of heat radiating type motorcycle engine cylinder block as shown in Figures 3 and 4, comprise piston chamber 1, cylinder inner wall 2 and chain chamber 3, cylinder inner wall 2 is between piston chamber 1 and chain chamber 3, the periphery of piston chamber 1 is convexly equipped with some first radiating fin 4, each first radiating fin 4 all has through hole 6, through hole 6 on some first radiating fin 4 spatially forms helix structure, the bi-side of some first radiating fin 4 are all evenly distributed in some waveform second radiating fin, and the length direction of some second radiating fin 5 overlaps with the radial direction of the first radiating fin 4.
Embodiment 2 is only with the difference of embodiment 1: the second radiating fin 5 is waveform, and it is larger that described wave shaped radiator compares heat diffusion area than flat radiating fin, and radiating effect is better.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
