Abstract

The invention discloses a ventilating machine provided with a tight fitting type fan cover. The ventilating machine comprises a ventilating machine box body and two side cylinder heads connected with the ventilating machine box body and further comprises the fan cover and an air guide cover module penetrating through an airtight air channel and used for cooling the ventilating machine box body and the two side cylinder heads. Due to the fact that the edge peripheries of the air guide cover module and the fan cover form an airtight through cooling space through right fitting, the leakproofness of the whole cooling space is greatly improved, air flow loss in the cooling space is reduced, and heat dissipation effect is ensured. In addition, in the mode that the fan cover and the air guide cover module form the tight fitting structure, the ventilating machine is more compact in overall structure and capable of saving space.

Description

technical field [0001] The invention relates to the field of forced air-cooled ventilator cooling, in particular to a ventilator with a close-fitting windshield. Background technique [0002] The cooling air passage of the traditional general-purpose gasoline engine forced air cooling system is usually composed of heat sinks of the box body and cylinder head, fan cover parts and more air guide covers. The fan cover and air guide cover are made of injection molding or metal Manufactured by stamping technology, and connected with the box body or cylinder head by bolts. The formation process of the cooling air flow is: under the action of the impeller, the air is continuously gathered into a certain space formed by the fan cover part, the box body, and the cylinder head, so that the space The pressure increases, and under the action of pressure, the air will flow along the reserved channel connected to this space, that is, the air duct composed of the air guide cover, the box b...
