Abstract
The utility model relates to a cylinder cover with radiating fins, wherein the cylinder cover is fixedly arranged on a cylinder head of a four-stroke engine, and is characterized by comprising a cylinder cover body and a plurality of radiating fins, wherein the cylinder cover body consists of one external top surface and four external lateral faces, and a plurality of the radiating fins are fixedly arranged on at least one face of the external top surface and the four external lateral faces. Therefore, the radiation effect of the cylinder cover can be increased through arranging a plurality of the radiating fins on the cylinder cover body, the temperature of the cylinder head of the engine can be reduced, further the engine can not be overheated in the operation process, and can not cause the low efficiency and damage of the engine.
Description
Technical field
The utility model relates to a kind of cylinder head of tool radiating fin, refers to a kind of cylinder head that is applicable to the tool radiating fin of four-journey engine especially.
Background technique
General four-journey engine is to see through the four-journey of air inlet that cylinder internal goes round and begins again, compression, blast, exhaust and produce continuously power.Wherein, the piston chamber of cylinder block inside, since the high speed to-and-fro motion of piston, the high heat of inevasible generation.Therefore,, generally all can be convexly equipped with many fins, utilize forced air-cooled mode,, avoid the engine operating temperature too high and influence performance in the hope of smoothly the high temperature that cylinder wall bore being dissipated to the outside to increase heat diffusion area in the cylinder head outside of cylinder block.
See also Fig. 1.It is the stereogram of known cylinder head and cylinder head.As shown in the figure, the higher authorities at the separating casing body have a cylinder head 92 to be covered on the cylinder head 91, cylinder head 91 itself then has most radiating fin 911 in order to heat radiation, but cylinder head 92 does not often have radiating fin, because engine is in running, because of the thermal source that the firing chamber produced, cause cylinder head 91 operating temperatures own very high, and cylinder head 91 is covered by cylinder head 92, and cylinder head 92 lacks radiating fin again, cause the radiating effect of cylinder head 91 also bad, thereby make cylinder head 91 and near the cylinder head 92 high temperature be difficult to leave, to the radiating effect of engine integral body and bad, and then influence the efficient of engine running, so it is not very good commonly using the design of cylinder head, and the space of improvement is still arranged.
The creation popularity originally in the spirit of positive creation, is urgently thought a kind of cylinder head of the tool radiating fin that can address the above problem because of in this, and several times research experiment is eventually to finishing the utility model.
The model utility content
The purpose of this utility model provides a kind of cylinder head of tool radiating fin, to improve the radiating effect of engine integral body.
The purpose of this utility model is achieved in that a kind of cylinder head of tool radiating fin, and cylinder head is fixedly arranged on the cylinder head of a four-journey engine, and cylinder head includes: a cylinder head body, and most radiating fin.Wherein, the cylinder head body includes an outer end face, and side all round, and most radiating fin then are fixedly arranged on one of them face of five of the outer end face of cylinder head body and sides all round etc.
In addition, an above-mentioned majority radiating fin can parallelly distribute, maybe can be equally distributed on one of them face of five of the outer end face of cylinder head body and sides all round etc., all can reach the effect that increases radiating effect.In other words, the demand of the visual heat dissipating capacity of artificer, with the cylinder head body be designed to only have one side or two or three or four sides or simultaneously five faces all be installed with radiating fin.
In addition, an above-mentioned majority radiating fin also can be positive miter angle oblique parallel and distribute, maybe can be negative miter angle oblique parallel and be distributed on the outer end face of cylinder head body, all can reach the effect that increases radiating effect.
Moreover, the utility model cylinder head is applicable be mounted on four-journey locomotive engine, general with power traction hold up, on lawn mower engine or the car engine, and also applicable being mounted on ventilation type or the water-cooled four-journey engine, it all can reach the increase radiating effect, increases the effect of engine efficiency.
The utility model has the advantages that,, can increase radiating effect, thereby can reduce the cylinder head inside temperature of engine, and then impel engine in operation process, can not cause engine efficiency to reduce or damage because of overheated owing to add most radiating fin at the cylinder head body.

Embodiment
Please consult Fig. 2 to Fig. 6 simultaneously, it is respectively plan view, plan view, worm's eye view, left view and the right elevation of the utility model first preferred embodiment.Present embodiment is a kind of cylinder head of tool radiating fin, and cylinder head is fixedly arranged on the cylinder head of a four-journey engine, and cylinder head includes: a cylinder head body 10, and most radiating fin 20,21,22,23,24.In the present embodiment, four-journey engine refers to air-cooled four-journey locomotive engine.
As shown in the figure, cylinder head body 10 includes an outer end face, and side all round, and most 20,21,22,23,24 of radiating fin are fixedly arranged on the outer end face of this cylinder head body 10, and all round on the side.In the present embodiment, the outer end face of cylinder head body 10 with all be installed with radiating fin 20,21,22 on the side all round, 23,24, and most radiating fin 20,21,22,23,24th, parallel and equidistant and be in vertical distribution in four outer side surfaces of cylinder head body 10 and outside on the end face.
By this, the utility model adds most radiating fin 20,21 in cylinder head body 10,22,23,24, can increase radiating effect, thereby can reduce the cylinder head temperature inside of engine, and then impel engine in operation process, can not cause engine efficiency to reduce or damage because of overheated.
Please consult Fig. 7 again, it is the plan view of the utility model second preferred embodiment, the present embodiment and first embodiment's difference only is that the radiating fin 30 that is set firmly on the outer end face of cylinder head body 10 of present embodiment is to be negative miter angle oblique parallel and equidistantly to distribute, first embodiment's radiating fin 20 then is that vertical distribution is on outer end face, present embodiment also can be reached first embodiment's increase radiating effect, and then reduces the effect of the cylinder head inside temperature of engine.
