Description

A kind of external air-cooled oil cooler

Technical field

It the utility model is related to motorcycle engine cooling technology field, and in particular to a kind of external air-cooled oil cooler.

Background technology

Engine is the power resources of motorcycle, and is explosive motor, it was found from its principle, explosive motor combustion Heat caused by burning only has 25%~35% can be changed into mechanical work or effective power, and remaining 65%~75% heat is Needing what is distributed, a part is discharged by waste gas, but highest can only also discharge 30% heat, and remaining 30% or so Heat can only be radiated by in-engine machine oil and engine housing.And cylinder block, cylinder head, work on engine The heatproof limitation of the parts such as plug, if without cooling down in time, part can produce thermal expansion, so as to cause the card of moving part Extremely, so as to causing engine damage.Existing motorcycle has natural wind cooling, air blast cooling but and several cooling sides of oil injection type Formula, but natural wind cooling is only to utilize the contact area for increasing fin and air, so that heat is pulled away, but the effect to radiate Fruit is poor, easily overheats parts；And air blast cooling is to make fan blade strong using rotary motion caused by crankshaft operation Air-flow is stirred, natural wind is introduced and pressure cooling is carried out to external engine, but needs to expend the load of crankshaft main bearing, bearing pole It is easy to wear；Oil injection type is back to again in crankcase after being transported to radiator cooling using in-engine lubricating oil, to ensure Inside is in lower temperature, but existing oil injection type directly allows machine oil to be radiated by fin, and fin is not filled It can be flowed, cause the wasting of resources, furthermore existing motorcycle engine can only have the one of which type of cooling, cooling Effect or relatively low.

Utility model content

For the deficiency in the presence of prior art, the utility model provides a kind of external air-cooled oil cooler, solves Prior art only has a kind of type of cooling, cooling effect to pay no attention to the problems such as thinking of the wasting of resources.

To achieve the above object, the utility model employs following technical scheme：A kind of external air-cooled oil cooler, including It is arranged with the first oil pipe and the second oil pipe that both ends seal in parallel, some skies is provided between first oil pipe and the second oil pipe The fin of the heart, and each fin communicates with inside the first oil pipe and the second oil pipe；First oil pipe by first every Plate is divided into oil-feed section and the first breeze way, and is provided with oil inlet in oil-feed section；Second oil pipe is separated by second partition For the second breeze way and fuel-displaced section, and oil-out is provided with fuel-displaced section；First oil pipe and the second oil pipe both ends, which are provided with, to be used In two side plates of interconnection；The fin side is additionally provided with radiator fan, and radiator fan passes through connecting plate and two Side plate is connected.External air-cooled oil cooler is installed on motorcycle stand, in-engine machine oil flows into the by oil inlet The oil-feed section of one oil pipe, then flowed into by fin after the second breeze way of the second oil pipe and the first oil is flowed into by fin again First breeze way of pipe, further by fuel-displaced section of fin the second oil pipe of inflow, finally by fuel-displaced on fuel-displaced section Mouth is flowed back in engine, the distance that increase machine oil flows in fin, makes radiating more abundant；When machine oil flows in fin While, the radiator fan positioned at fin side rotates at a high speed, so as to be forcibly introduced into more natural wind circulation fin Surface, the effect with air heat-exchange is further strengthened, air-cooled with the double action of oil cooling, in-engine machine can be made Oil radiating faster, ensure that the radiating effect of parts on engine, so that its life, failure rate reduces.

Compared to prior art, the utility model has the advantages that：Increase dividing plate makes full use of dissipating for fin Hot area, increase engine oil flow distance, so as to increase machine oil and the effect of fin heat exchange, the radiator fan positioned at outside enters one Step accelerates the circulation of fin surrounding air, improves the heat exchange efficiency of fin and air.
