Summary of the invention
The purpose of this utility model is to exist above-mentioned problem at existing cylinder, and the cooling system of a kind of simplicity of design, good heat dissipation effect, cylinder that cost of production is low is provided.
The purpose of this utility model can realize by following technical proposal: a kind of cooling system of cylinder, comprise engine cylinder body with cylinder hole, a described cylinder block wherein side has the cam chain chamber that is used to install cam chain, all has radiating fin on other side of cylinder block, it is characterized in that, described cam chain is indoor to be provided with heat-conducting piece and described heat-conducting piece two outer walls are close to respectively on cylinder block outer side wall and the indoor sidewall of cam chain, and described heat-conducting piece adopts metallic material to make.
Motor is when work, form high temperature in the engine cylinder body cylinder hole and be delivered on the outer wall of cylinder block, wherein on the cylinder block outer wall wherein the heat of a side be delivered on the cam chain chamber by heat-conducting piece, and the area of contact of utilizing cam chain chamber outer wall and air reduces the temperature of cylinder block, and other side of cylinder block utilizes the area of contact of radiating fin and air to reduce the temperature of cylinder block, thereby make engine cylinder body cylinder hole that uniform thermal expansion be arranged, avoid the cylinder bore deformation.
In the cooling system of above-mentioned cylinder, have symmetrically arranged cambered surface groove on described cylinder block outer side wall and the indoor sidewall of cam chain, be the arc surface that is complementary with described cambered surface groove at above-mentioned heat-conducting piece two outer walls.Make heat-conducting piece be positioned on cylinder block outer side wall and the indoor sidewall of cam chain like this and can double swerve, improve stability.
In the cooling system of above-mentioned cylinder, described heat-conducting piece is fixed with rubber sheet gasket on the upper-end surface.Can reduce the vibration and the noise of motor by rubber sheet gasket, and play fixing heat-conducting piece and prevent the effect that comes off.
In the cooling system of above-mentioned cylinder, described heat-conducting piece has draw-in groove on the upper-end surface, has card base and described card base on the described rubber sheet gasket and fixes in draw-in groove.Make being fixed on the heat-conducting piece that rubber sheet gasket can be firm like this, rubber sheet gasket is occurring being convenient for changing rubber sheet gasket again when damaged simultaneously.
Compared with prior art, the cooling system of this cylinder by be arranged on the indoor heat-conducting piece of cam chain with the heat transfer on the cylinder block to the cam chain chamber outer wall, make cylinder block also can transmit the heat of cylinder block inboard in this side of cam chain like this, thereby the outer side surface of cylinder block all can be dispelled the heat, make engine cylinder body cylinder hole that uniform thermal expansion be arranged, avoid the distortion in cylinder hole, installation and processing is convenient, cost of production is low; Simultaneously on heat-conducting piece, be fixed with rubber sheet gasket, play the vibration and the noise that reduce motor, also play the fixedly effect of heat-conducting piece simultaneously.
