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...

Abstract

The invention discloses a fan cover for a general gasoline engine. The fan cover comprises a fan cover body, wherein a base plate used for forming a cylinder head cooling air passage is arranged on the fan cover body through inwards extending in the axial direction. The self structure is compact, the sealing performance of a cooling space is improved, the air flow loss in the cooling space is reduced to the maximum degree, the heat radiation effect is ensured, and in addition, the integral air passage structure is compact. In addition, the fan cover has the advantages that the realization of the structure is simple, the operation is convenient, in addition, the dismounting, the mounting and the maintenance are easy, and the fan cover can be easily replaced.

Description

technical field [0001] The invention relates to the field of forced air-cooled fan cooling, in particular to a fan cover for a fan. 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 body and the cylinder head heat...
