The invention provides a heat dissipation structure of an engine. The heat dissipation structure of the engine mainly comprises a cylinder body of an air cylinder, a crankshaft box, a centrifugal fan, an air collecting cover as well as a plurality of heat dissipation fins arranged on the outer surface of the crankshaft box, wherein the heat dissipation fins are respectively provided with a plurality of through holes; the through holes in the adjacent heat dissipation fins are arranged around the same central shaft so as to form a cooling air channel; the through holes positioned in the same heat dissipation fin are arrayed into a plurality of rows. Compared with the prior art, the invention provides the heat dissipation structure of the engine; the longitudinal heat dissipation fins are provided with a plurality of through holes so as to form the cooling air channel, and further the heat on the surfaces of the heat dissipation fins is taken away by the centralized flowing of cooling air rapidly, so that the heat dissipation efficiency is improved.
Description
technical field [0001] The invention relates to an automobile engine, in particular to a cooling structure suitable for the engine. Background technique [0002] Existing engines include casings and engines, and the cylinder parts of the engines generate large amounts of heat and are high in temperature. Timely heat dissipation and cooling are required to ensure good working conditions and long service life of the engines. [0003] The heat dissipation structure of the engine is mainly composed of a heat dissipation fan and a heat sink arranged on the engine. The heat dissipation fan discharges the air passing through the heat sink to the engine for heat dissipation. The cooling air flow channel and flow distribution of this cooling method are uncontrollable, and the heat dissipation effect is too poor. affect the performance of the engine. Contents of the invention [0004] In view of the above problems, the present invention provides an engine heat dissipation structure...
