Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of engine flywheel, especially relates to a high -efficient heat radiation structure for engine flywheel. BACKGROUND

[0002] In today's industrial field, as the power core of many mechanical equipment, the stable operation of engine plays a decisive role in the normal operation and performance of equipment. The engine flywheel is one of the key components of the engine, which undertakes the important responsibilities of storing energy, stabilizing speed and assisting starting. In the actual work of the engine, the flywheel will generate a large amount of heat due to various factors. On the one hand, during the gear shifting of the vehicle or the start-stop stage of the equipment, the flywheel and the clutch will produce significant heat due to frequent friction. On the other hand, when the flywheel rotates at high speed, the friction with the surrounding air and the interaction between the internal mechanical parts will also continuously generate heat energy and accumulate on the flywheel. In order to ensure the normal operation of the flywheel and avoid the influence of performance due to overheating, the flywheel shell needs to be equipped with a heat dissipation structure to quickly dissipate heat for the internal flywheel.

[0003] The existing flywheel shell usually adopts simple air cooling and heat dissipation fins for heat dissipation. The simple air cooling method is limited by the natural convection ability of air, and the heat dissipation efficiency is low. Especially when the engine is in a high load running state, the heat generated by the flywheel increases significantly, and the air cooling method often cannot quickly and effectively dissipate the heat, resulting in continuous temperature rise of the flywheel. Therefore, a high-efficiency heat dissipation structure for engine flywheel is proposed. SUMMARY
