Find out obviously that from Fig. 4 in this embodiment, the number of the radiating fin 30 of heat radiating fin structure 31 is for example 6.Parallel radiating fin 30 extends along the traffic direction of vehicle.Strengthen ridge or protrude 34 integrally formed with radiating fin 30 on the surface of radiating fin 30.Each strengthens protrudes the 34 height vertical extent along radiating fin 30.The surface that strengthens protrusion 34 has the cross section of circular shape in horizontal plane.Suitably, strengthening protrusion 34 has from the mild bending sections that raises of the plat surface of radiating fin 30.What recommend is to avoid using the enhancing of the cross section with band angle to protrude.Each of adjacent radiating fin 30 strengthen to protrude 34 with respect to the perpendicular direction of radiating fin 30 width direction of vehicle (promptly along) not relative to each other.
The height of enhancing protrusion 34 is far smaller than the distance between the adjacent radiating fin 30.Therefore, even each of adjacent radiating fin 30 strengthen to protrude 34 with respect to relative mutually with the perpendicular direction of radiating fin 30, also can between protruding 34, relative enhancing form the gap; Promptly, form to strengthen protrude 34, make each of adjacent radiating fin 30 strengthen protrude 34 with respect to the state not relative mutually with the perpendicular direction of radiating fin 30 under, it is 34 separated from each other that the enhancing of adjacent radiating fin 30 is protruded.One enhancing in the adjacent radiating fin 30 is protruded 34 and is free of attachment on the part that is not provided with the surface that strengthens protrusion 34 of another radiating fin 30.
As illustrate among Fig. 4 along Fig. 5 of the enlarged cross-sectional view of V-V line intercepting and obviously find out, strengthening and protrude the height that 34 length is slightly less than radiating fin 30, this enhancings protrusion 34 is formed on the described radiating fin 30.Each strengthen to protrude 34 from raising gradually a shade below the part of the radiating fin 30 of the top of radiating fin 30 mode with broad warp, extends to the diapire 35 that extends between adjacent radiating fin 30 downwards linearly.As shown in the figure, importantly, determine that size makes when along the direction that is parallel to the length of radiating fin 30, when promptly seeing along the direction that enters into paper, each of adjacent radiating fin 30 strengthen protrude 34 not overlapped.When formation enhancing like this protruded 34, the straight diapire 35 that extends continuously along the length direction that is parallel to radiating fin 30 was formed between the adjacent radiating fin 30.Right-hand member radiating fin 30 shown in Fig. 5 right half part is not provided with to strengthen and protrudes 34.Therefore, right diapire 35 seems wideer than left diapire 35.In fact, two the mutual relative enhancings among Fig. 5 protrude 34 does not have not to be formed on identical position with respect to the length direction of radiating fin 30.Therefore, the width of all as many as right diapire 35 of width of the left diapire 35 of each enhancing protrusion 34.Have of the traffic direction extension of the zigzag fashion diapire 35 of the minimum width part corresponding along vehicle with this width.
Fig. 6 is the end view from the cylinder block 12 of the front side intercepting of vehicle.As shown in Figure 6, the upper surface of cylinder block 12 is provided with heat radiating fin structure 31, and this heat radiating fin structure 31 comprises radiating fin 30 and strengthens protrusion 34.Regularly (timing) chain (not shown) space of extending therein 39 is shown in Figure 6 on the right side, promptly with respect to the left side of the traffic direction of vehicle.As is generally known, timing chain is sent to camshaft with the rotation with bent axle being installed in the chain gear (not shown) on the bent axle and being installed in to extend between the driven chain gear (not shown) on the camshaft, this bent axle remains in the crankcase 11, and this camshaft is arranged in the valve gear housing.Radiating fin 32 is shown in the left side of Fig. 6.These radiating fin 32 comprise with the parallel vertical radiating fin 32a of the axis normal of cylinder with the parallel axes of cylinder and be connected the enhancing rib 32b of adjacent radiating fin 32a.Described enhancing rib 32b has the height of the height that is lower than radiating fin 32a.
As shown in Figure 6, the lower surface of cylinder block 12 is provided with the radiating fin 40a of the structural similarity of radiating fin 32 and strengthens rib 40b, and this strengthens rib 40b perpendicular to the adjacent radiating fin 40a of the axis splice connection of cylinder.The height that strengthens rib 40b is lower than the height of radiating fin 40a.Each strengthens rib 40b and all has outwards recessed edge part.Radiating fin 32 and 40 have based on patent document 1 in the heat radiating fin structure of the essentially identical principle of principle of the Structure of radiating fin mentioned.
The heat radiating fin structure that is used for the preferred embodiment of the present invention of on-vehicle internal combustion engine forms with above-mentioned structure.When vehicle operating, the air flows that enters is passed through housing 14, cylinder head 13, cylinder block 12 and crankcase 11 with cooling internal combustion engines 10.Strengthen to protrude 34 and on the surface of radiating fin 30, form, make each of radiating fin 30 strengthen to protrude 34 enhancings that can not be connected on adjacent radiating fin 30 and the adjacent radiating fin 30 to protrude 34 with radiating fin 30.Therefore, the rigidity of radiating fin 30 is passed through to strengthen protrusion 34 and is strengthened, and enhancing protrusion 34 has increased the surface area of heat radiating fin structure 31 to improve cooling capacity.Because it is different with the traditional heat-dissipating sheet, adjacent radiating fin 30 does not protrude 34 connections by strengthening, radiating fin 30 and strengthen and protrude 34 and do not form separated pit, and the continuous diapire 35 that extends through the length of radiating fin 30 is formed between the adjacent radiating fin 30.Therefore, enter into coarse sand in the space between the adjacent radiating fin 30 and dust granule and clod and be difficult to be accumulated in those spaces, even and coarse sand and dust granule and clod be accumulated in those spaces also can water flush away easily.34 pairs of air streams generation lower resistance are protruded in enhancing with broad warp cross section.
Each of adjacent radiating fin 30 strengthens protrusion 34 and alternately arranges, therefore can be limited in minimum zone by the reduction that strengthens the cross-section area that protrudes 34 air passagewayss that between adjacent radiating fin 30, form, and entered into relatively large coarse sand particles in the space between the adjacent radiating fin 30 and silt piece and seldom be enhanced and protrude 34 and stop, but can in the space, easily roll and easily leave this space.Therefore, each of the air passageways between the adjacent radiating fin all is cleaned easily.Because air passageways does not narrow down, so air can easily flow through air passageways.
Because from being parallel to the length direction of radiating fin 30, it is not overlapped that each of adjacent radiating fin 30 strengthens protrusion 34, cooling air can flow smoothly and pass space between the adjacent radiating fin 30, and coarse sand particles and silt piece can not rest in this space, make that described space can be easy to clean.
In the embodiment shown in the diagram, internal-combustion engine 10 is suspended from the main car frame 5, and main car frame 5 is from the head pipe 4 downward-sloping rear portions that extend to of motorcycle, and air intake system 20 is arranged in the space between main car frame 5 and the cylinder head 13.Therefore, when vehicle operating, the rainwater that adheres to main car frame 5 and air intake system 20 drops on the heat radiating fin structure 31 on the top of internal-combustion engine 10 easily.Rainwater can easily flow along the traffic direction of vehicle and separate from heat radiating fin structure 31 with the rainwater that those have dripped on the heat radiating fin structure 31, do not form separated pit because radiating fin 30 and enhancing protrude 34, but form the continuous diapire 35 that extends along traffic direction.
As shown in Figure 4, shown in the embodiment shown in the diagram, for example, left end radiating fin 30, promptly on its facing surfaces, be provided with to strengthen with respect to the outermost end radiating fin 30 of vehicle width and protrude 34.Outermost end radiating fin 30 can not be provided with any enhancing and protrude 34, or can be only be provided with any enhancing at it on respect to the outer surface of the width of vehicle and protrudes; That is to say that with respect to the width of vehicle, the outer surface at least of outermost end radiating fin 30 can not be provided with to strengthen and protrude 34, this has improved the outward appearance of the motor that comprises heat radiating fin structure 31.
