Embodiment Construction
[0016] As shown in the figure: the fan cover for the general machine in this embodiment includes a fan cover body 1, and the fan cover body 1 extends axially inwardly and is provided with a base plate 2 for forming a cooling air duct for the cylinder head of the general machine; Generally, an impeller is provided on the fan cover, and the fan cover and the air guide part form an air duct for cooling the cylinder block of the fan cover. Extending inwards not only saves components and makes the overall structure compact, but also greatly improves the airtightness of the cooling space, reduces the airflow loss in the cooling space, ensures the heat dissipation effect, and makes the overall structure compact.
[0017] In this embodiment, the substrate 2 is provided with a plug-in structure for plugging the plug-in board and the base board 2 together to form a cooling air duct; wherein, the plug-in board can realize the function of diversion, and its plug-in cooperation with the bas...
