Efficient heat dissipation device for engine

Abstract

An efficient heat dissipation device for an engine includes a frame and an axial flow fan. The frame is connected to the engine. The axial flow fan is rotatably arranged on the frame and is driven by the engine crankshaft. In this embodiment, the axial flow fan supplies air along the fan axis. The size of the axial flow fan is large enough so that the air distribution area can cover the entire engine. The efficiency of heat dissipation is improved as the various parts of the entire engine can be air-cooled from one side at the same time. In addition, compared with the combined heat dissipation solution of a centrifugal fan and an air guide cover, the direct air supply of the axial flow fan directly blows the engine without kinetic energy loss, further improving the heat dissipation efficiency.
