Abstract
The utility model relates to a radiating structure of an all-purpose petrol engine crankcase, which comprises a crankcase and a cylinder body which are connected in one piece. A plural of criss-crossed radiating fins are arranged on the bottom and top portions of the crankcase, and the air outlets on the bottom and top portions of the crankcase are just opposite to the radiating fins. The radiating structure of an all-purpose petrol engine crankcase has the advantages that the temperature of lubricating oil in the crankcase can be decreased, thus the heat dissipation effect is excellent, and the intensity of the crankcase is increased.
Description
Technical field
The utility model relates to a kind of crankcase body, particularly a kind of radiating structure with general gasoline engines crankcase body of very high thermal diffusivity.
Background technique
The general gasoline engines crankcase body is generally used for installing the lubricant oil of bent axle, bearing and splendid attire petrol engine, general gasoline engines in the course of the work, lubricant oil in the crankcase body is lubricated cooling by certain lubricating oil path to the component of motor, with proper functioning and lubricated each moving element of guaranteeing motor, increase the working life of petrol engine part.Because lubricant oil when lubricating cooling petrol engine component, needs to absorb a large amount of heats and its temperature is raise, and is collected at the internal surface of crankcase body shell.Present crankcase body makes the cooling of can not well dispelling the heat of wherein lubricant oil, influences the cooling effect of lubricant oil to the petrol engine component, has reduced petrol engine working life.In addition, existing crankcase body structure is easy to be shaken in petrol engine work and splits, and also has big defective on the intensity.
Summary of the invention
At above-mentioned technical problem, it is a kind of simple in structure that the utility model provides, the radiating structure of the general gasoline engines crankcase body of good heat dissipation effect.Adopt the radiating structure of general gasoline engines crankcase body of the present utility model can reduce the temperature of lubricant oil in the crankcase body, good heat dissipation effect, and have the advantage that increases crankcase body intensity.
The technical solution of the utility model is: be provided with crisscross some radiating fin at the crankcase body bottom and the top that are connected with the cylinder block one, the exhaust outlet of crankcase top and bottom is over against radiating fin.
The height of described vertical radiating fin, width are greater than height, the width of heatsink transverse sheet.
Adopted such scheme, crisscross radiating fin has been set in the top and the bottom of general gasoline engines crankcase body, the one, the effect of playing stiffening rib has increased vertical, the horizontal intensity of casing; Main is to have increased whole crankcase body surface radiating area, helps the heat radiation of casing top and lower surface.The exhaust outlet that makes crankcase top and bottom can be used to take away from the cooling air of exhaust outlet the heat of crankcase body top and lower surface over against radiating fin, makes radiating effect better.Simultaneously, make the height, width of vertical radiating fin height, width greater than the heatsink transverse sheet, help cooling air from exhaust outlet at the casing top, bottom (especially bottom) along forming the cooling air passage between two vertical radiating fin, and then flow by concentrating of cooling air and to take away its surperficial heat.Therefore,, not only increased the intensity of casing top, bottom, the more important thing is the radiating effect that can strengthen casing top, bottom by above radiating structure.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of general gasoline engines crankcase body;
Fig. 2 is the radiating structure schematic representation of general gasoline engines crankcase body bottom;
Fig. 3 is the radiating structure schematic representation at general gasoline engines crankcase body top.
In the accompanying drawing, 1 is crankcase body, and 2 is cylinder block, 31,32,33,31 ', 32 ', 33 ' be exhaust outlet, 4 is vertical radiating fin, 5 is the heatsink transverse sheet.
Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, be provided with crisscross some radiating fin in crankcase body 1 bottom that is connected with cylinder block 2 one and top.Present embodiment is provided with 5 vertical radiating fin 4 and 9 heatsink transverse sheets 5 in crankcase body 1 bottom, the height of its vertical radiating fin, width are greater than height, the width of heatsink transverse sheet, crankcase bottom is provided with 3 exhaust outlets 31,32,33, and exhaust outlet is over against the radiating fin of crankcase bottom.Present embodiment is provided with 5 vertical radiating fin 4 and 8 heatsink transverse sheets 5 at crankcase body 1 top, the height of its vertical radiating fin, width are greater than height, the width of heatsink transverse sheet, the crankcase top be provided with 3 exhaust outlets 31 ', 32 ', 33 ', exhaust outlet is over against radiating fin.When petrol engine in when work, the part heat of lubricant oil passes to top, the bottom of crankcase body, by crisscross radiating fin is set, has played the effect of stiffening rib and has enlarged markedly heat diffusion area; Cooling air from cooling fan is discharged from exhaust outlet, because exhaust outlet is over against radiating fin, and vertically the height, width of radiating fin forms a good heat dissipation channel greater than height, the width of heatsink transverse sheet, the heat wind that is cooled is rapidly taken away, and has improved the radiating effect of lubricant oil greatly.
Claims (3)
1. the radiating structure of a general gasoline engines crankcase body, comprise crankcase body and cylinder block that one connects, it is characterized in that: be provided with crisscross some radiating fin in crankcase body bottom and top, the exhaust outlet of crankcase top and bottom is over against radiating fin.
2. the radiating structure of general gasoline engines crankcase body according to claim 1 is characterized in that: the height of described vertical radiating fin is greater than the height of heatsink transverse sheet.
