For one oil, the working fluid in about 140 221 can be reached. At this time, the high temperature vapor phase absorbs heat in the cooling flow passage 23. In addition, the oil drop in the greenhouse 14 ^ after cooling down, the job is connected to the clear oil road 15 by the oil outlet, first through the filter, oil loaded f 16 it line through the 'oil oil can follow the oil road 15 The crankcase 12 is fitted to lubricate its internal components. After the in-service component, the cycle of the above-mentioned oil cooling is resumed. Therefore, the hot parent converter 20 of the first embodiment of the present invention can utilize the two-phase $ latent heat absorption/release principle of the working fluid 2 of the heat dissipating component 22 to achieve a simple heat conduction and heat convection principle directly by using the heat exchange body 221. It is also more than ten times more efficient in heat exchange. At the same time, it is equipped with a cooling water system composed of related components such as the cooling flow passage 23 to provide a water-cooling heat-dissipating function to instantly dissipate heat and ensure the heat-dissipating component. The working fluid 225 of 22 is continuously changed between the liquid phase and the vapor phase to surely carry away the thermal energy of the oil in the crankcase 12. Referring to FIG. 3, the engine oil cooling structure of the internal combustion engine according to the second embodiment of the present invention is similar to the first embodiment of the present invention, and the figure of the first embodiment is used, but the difference between the two is characterized by: The heat exchanger 2 of the second embodiment omits the water-cooling heat dissipation structure such as the cooling flow passage 23 and the water pump 3 of the first embodiment, but is further modified to have a plurality of scattered surfaces on the surface of the heat exchange body 221. ^ Fin 24' to provide an air-cooled heat sink construction. The heat dissipating fins 24 are preferably formed on the heat exchange body 221 or may be prefabricated and then assembled on the heat exchange body 221 in an appropriate manner. The manufacturing or assembling method is not used to limit the present invention. . When the oil is cooled, the working liquid 225 of the heat dissipating member 22 brings thermal energy to the heat releasing end 222, and the heat energy is then thermally conducted to the heat exchange body 21 and the heat dissipating fins 24. In this way, the heat dissipating fins 24 can conduct heat energy to the surrounding air to directly dissipate heat by using air. Moreover, if necessary, a fan or a shroud (not shown) can be used to force the air to dissipate the heat sink fins 24 to accelerate the efficiency of the air-cooled heat sink. Further, with respect to the first embodiment, the filter and oil unit 16 of the second embodiment is further modified to be disposed at the intake port 131 of the oil pump chamber 13, i.e., on the upstream side of the oil pump 133. In this way, the oil flowing through can also be subjected to the smashing action. In the first embodiment of the present invention, the position of the oil filter device can be changed to the setting mode of the second embodiment. Similarly, the second embodiment can also filter the filter. The position of the oil device 16 is changed to the setting mode as in the first embodiment. Referring to FIG. 4, the engine oil cooling structure of the internal combustion engine according to the third embodiment of the present invention is similar to the first embodiment of the present invention, and the figure of the first embodiment is used, but the difference between the two is characterized by: The third embodiment changes the relative upstream and downstream positions of the oil pump chamber 13 and the oil drop greenhouse 14, wherein the oil drop greenhouse 14 is located upstream of the oil pump chamber 13, and the oil inlet 141 of the oil drop greenhouse 14 is connected to The oil chamber is simultaneously connected to the extraction port 131 of the oil pump chamber 13 and is then communicated by the supply port 132 to the lubricating oil passage 15 of the internal combustion engine 10. Thus, the oil pump 133 of the oil pumping chamber 13 can also drive the oil from the oil chamber 12 into the oil drop greenhouse 14 to ensure that all of the oil can be circulated for heat dissipation. Further, the oil spring, the °3, and the gradual oil passage 15 of the oil chest chamber 13 are further connected to the filter and oil unit 16, so that the oil flowing through the county passes through the county. In addition, with respect to the first embodiment, the heat absorbing end 221 of the heat dissipating member 22 of the third embodiment has a l-shaped bending shape, and functions as: the oil inlet (4) and the oil outlet 142 of the oil drop greenhouse 14. There is a - shortest flow path pinch (not shown) so that the oil input from the oil inlet 141 can be moved monthly to the oil outlet 142 via the shortest flow path. Therefore, the heat absorbing end 221 of the heat dissipating 7G member 22 is stepped and extended to the shortest flow path to ensure the most efficient heat dissipation action for all the oil flowing through. In addition, in addition to the heat absorbing end 221, the heat releasing end 22 may also be in a l-shaped bend shape to increase the contact area with the heat exchange body 21 to improve the transfer of thermal energy to the hot parent exchange body 21. effectiveness. The heat absorbing end 221 or the heat releasing end 22 can be formed into various suitable bent shapes such as an L shape, a U shape, a wave shape or a spiral shape. In the present invention, depending on the design requirements of the product, the bending design of the heat absorbing end 221 (or the heat releasing end 22) of the heat dissipating member 22 can also be selectively applied to the first or second embodiment to increase the oil drop greenhouse as much as possible. The oil cooling effect. Referring to Fig. 5, the oil drop of the internal combustion engine of the fourth embodiment of the present invention is similar to the third embodiment of the present invention, and the figure of the third embodiment is used, but the difference between the two is characterized by: In the fourth embodiment, the water-cooling heat dissipation structure such as the cooling flow passage 23 and the water pump 30 of the third embodiment is omitted, but further, at least one heat dissipation cone 24 is protruded from the surface of the heat exchange body 221 to provide a gas. The cooling heat dissipation structure has the same heat dissipation principle as the second embodiment of the present invention. In addition, with respect to the second embodiment, the oil filtering device of the fourth embodiment is further modified to be disposed at the oil inlet 141 of the oil drop greenhouse 14, that is, the oil drop greenhouse 14 and the oil chamber 12 are disposed. between. In this way, it is also possible to filter the oil flowing through it. In addition, the oil of the fourth embodiment is cooled to 14 and 6 and has at least one partition 143, which functions to: the shortest flow originally having a straight line between the oil 141 and the oil ρ 142 of the oil drop greenhouse The path (not labeled 'can be referred to as the second, third or fourth ride), so that the oil input by the oil inlet 141 may be directly moved to the machine/甴 exit 142 via the shortest flow path. Therefore, the oil drop greenhouse 14 can use the partition plate 143 to block the shortest flow path which is originally linear, that is, change the flow direction of the oil so that all the oil can bypass and flow through the heat absorption end 221 of the heat dissipating member 22 to Ensure the most efficient heat dissipation for all oil flowing through. Furthermore, the partition 143 can also be used to increase the structural strength of the oil drop greenhouse 14. In the present invention, depending on the design requirements of the product, the barrier design of the partition 143 of the oil drop greenhouse 14 can also be selectively applied to the first or second embodiment to maximize the oil cooling effect of the oil drop greenhouse 14 (even The spacer 143) may be appropriately disposed in accordance with the bent shape of the heat absorption 4 221 of the heat dissipating member 22 12 1359901 of the third embodiment. In addition, the position of the third embodiment of the functional brain device 16 is changed to the & embodiment of the detailed embodiment; similarly, the fourth embodiment can also set the oil slinging device 16 as the third embodiment. . As described above, the water-cooled or air-cooled cooling system of the conventional engine internal combustion engine cooling system uses only heat conduction or heat convection to dissipate heat, resulting in the inability to achieve both volume miniaturization and improved heat exchange efficiency. The invention of 丨 to 5 is directly under the oil pump 14 in the crankcase U by the oil pump 133 and the internal heat sink 22' Heat absorption is performed, and heat is conducted to the heat exchanger 2 outside the crankcase 11 to perform efficiency. The setting of the oil drop greenhouse 14 ensures that all the oil is circulated and cooled, thereby improving the cooling efficiency of the oil. Since the heat dissipating element is extremely small, the heat principle of the two-phase change is that the crankcase = all the oil is quickly dissipated, and the heat exchanger is not required to be added, and the volume 'further facilitates the heat exchange H 2〇 Miniaturization. Furthermore, the n heat dissipation member 22 will make the axle box 11 _ unexpectedly that the crankcase H does not need to transport any oil to the crankshaft via any additional ducts, so that the oil stays completely in the crankshaft. The box u Θ is used for lubrication and heat absorption, and the running performance of 1 can also greatly reduce the manufacturing cost of the warranty. In addition, the present invention can also ensure that the heat dissipating component facilitates the heat energy of all the ages flowing through the heat dissipation element 22 by disposing the heat dissipating element 22, or the 221, or the baffle 143.佳 倾 倾 倾 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Fig. 1 is a sectional view showing the combination of the oil cooling structure of the internal combustion engine according to the first embodiment of the present invention.
