[embodiment]
The utility model mainly is a heat dissipation element 3 to be arranged at engine more easily produce the part of high temperature to carry out the cooling function, this heat dissipation element 3 as shown in Figure 5, be to establish a stamen heart 32 in a conduit 31 inboards, be filled with cooling liquid in this stamen heart 32, and be a hollow portion 33, and establish the heat insulation layer 34 of a suitable length in conduit 31 neutral position in the inboard of the stamen heart 32 (being the central authorities of heat dissipation element).And its action principle is: with this heat dissipation element 3 wherein an end (heating end) be inserted in the high temperature place, then the heat energy at this high temperature place can conduct to the stamen heart 32 through conduit 31, and the cooling liquid that the stamen heart 32 includes is after absorbing heat energy, because of becoming steam, the high temperature that continues enters hollow portion 33, steam also flows to colling end by heating end, and the colling end of heat dissipation element 3 is with after cool air or cooling water contact, steam can be replied to aqueous because of the condensation knot, and absorb by the stamen heart 32, while heat energy also drains into the external world and reaches heat sinking function, and the cooling liquid of the stamen heart 32 colling ends can flow to heating end because of wicking, and constantly circulation reaches cool effect by this.
Be easy to generate the position of high temperature because of running with regard to many cylinders air-cooling type engine, see also Fig. 6 and shown in Figure 8, air-cooling type twin cylinder 4 is because cylinder 41, the 42nd, be a mode side by side, so cylinder 41,42 adjacent regions in the running, because the not good nature of close together thermal diffusivity can form the state of higher temperatures, it is other that cylinder 41 nearly timing chains are provided with space 43 in addition, equally can be because of the not good generation higher temperatures of thermal diffusivity, and its settling mode be as Fig. 7 and shown in Figure 9, the heating end of heat dissipation element 3 is inserted in two cylinders 41, localized hyperthermia place between 42, the colling end of heat dissipation element 3 then is positioned at 44 of the radiating fin of twin cylinder 4, and cool off via cooling air passage A (seeing also cooling air passage A shown in Figure 1), plug heat dissipation element 3 in the same way and 43 adjacent localized hyperthermia places, space are set at cylinder 41 and timing chain, setting by heat dissipation element 3, two cylinders 41, adjacent localized hyperthermia place, 42 places and cylinder 41 nearly timing chains are provided with the localized hyperthermia on 43 sides, space, can be conducted by the heating end of heat dissipation element 3 by other side colling end and be discharged, make the cooling-down effect at this two localized hyperthermias place the same with other positions, and can reduce the distortion that cylinder Yin Wendu inequality is caused, and then improve the consumption of lubricating oil of engine, and avoid cylinder wall to cause the situation of scratch because of distortion.
See also shown in Figure 10ly, be air-cooling type single-cylinder 5, cylinder 51 is provided with space 52 adjacents with timing chain, because cylinder 51 and timing chain are provided with the space.52 because of being provided with radiating fin, therefore this adjacent can form local higher temperatures state naturally, so can be general as shown in figure 11, the heating end of heat dissipation element 3 is inserted in the localized hyperthermias place that cylinder 51 nearly timing chains are provided with 52 sides, space, in addition the side colling end then is positioned at 53 of the radiating fin of air-cooling type single-cylinder 5, and cool off via cooling air passage A (seeing also cooling air passage A shown in Figure 1), and absorb the temperature at this higher temperatures place, part by heating end, discharge heat radiation by the colling end that is positioned at the cooling system passage again, make cylinder 51 and timing chain that 52 adjacent localized hyperthermia places, space are set and to effectively reduce temperature, can not be subjected to the influence of high temperature in this part, with the distortion of avoiding being caused because of non-uniform temperature.
Again with regard to the cooling of air-cooling type cylinder head 61, see also Figure 12 and Figure 13, air-cooling type cylinder head 61 is to make oil gas introduce firing chamber 63 igniting from intake duct 62 fire, waste gas after firing is then discharged by the air outlet flue 64 of other side, and above firing chamber 63, establish a cooling air passage A (and seeing also cooling air passage A shown in Figure 1), to carry out the cooling of air cooling, because the combustion temperature of firing chamber 63 is quite high, therefore nearly valve base 65 places can form a local higher temperatures state, at nearly timing chain 66 sides, space are set in addition and can produce localized hyperthermia too, therefore as Figure 14 and shown in Figure 15, the heating end of heat dissipation element 3 is inserted in nearly valve base 65 other and nearly timing chains, and that space 66 is set is other, the colling end of heat dissipation element 3 then is positioned at the cooling air passage A (and seeing also cooling air passage A shown in Figure 1) of air cooling system, because the heating end of this heat dissipation element 3 absorbs the high temperature at this place, part, and by doing the colling end discharge heat radiation that thermoelement 3 is positioned at cooling air passage A, reach cool effect, the discharge so that these local high temperature effectively dispel the heat, improve the temperature distribution that nearly valve base 65 and nearly timing chain are provided with space 66, avoid nearly valve base 65 and nearly timing chain that the phenomenon that space 66 causes distortion to cause valve to seal because of temperature distributing disproportionation is set.
See also the water-cooled twin cylinder 7 of Figure 16 again, at cylinder 71,72 periphery is provided with cooling water passage B, use and carry out countercylinder 71,72 refrigerating function, but at two adjacent cylinders 71,72 then because this place is the state of a higher temperatures, so heat dissipation element 3 is inserted in two adjacent cylinders 71, between 72, and be to make heating end be positioned at two cylinders 71, between 72, the colling end of heat dissipation element 3 then is positioned at cooling water passage B, heat dissipation element 3 is utilizing heating end to draw two cylinders 71, behind 72 the high temperature, and with temperature conduction to the colling end that is positioned at cooling water passage B, and the radiating effect of lowering the temperature by cooling water, and can reduce by two adjacent cylinders 71,72 high temperature causes the facts of scratch to avoid cylinder wall because of distortion.
The position of setting up with regard to above stated specification heat dissipation element 3, not in order to limit the scope that the utility model is used, the utility model mainly is that heat dissipation element 3 is inserted in the position that more easily produces high temperature in the engine running, absorb the temperature at localized hyperthermia place by the heating end of heat dissipation element 3, the cooling function of utilizing cooling system to do to dispel the heat by other side colling end again, and then the cooling effect of increase engine integral body, and avoid the distortion that localized hyperthermia place member produced because of the chilling temperature inequality or the phenomenon of heat structure fatigue, prevent the inefficacy of member, and then prolong the working life of member.
