Embodiment Construction

[0017] As shown in the figure: the cooling air duct assembly for the general machine in this embodiment includes a fan cover 1 and a guide cover 2, and the guide cover 2 and the fan cover 1 are plugged together to form the cylinder head of the general machine Cooling air channel for cooling; the structure of the present invention is suitable for forced air-cooled fans, wherein the fan cover 1 is used to cover the impeller, and the fan cover 1 and the wind guide cover assembly are used to form an upper cooling for cooling the cylinder head of the fan Air duct, in this embodiment, the plug-in cooperation between the air deflector 2 and the fan cover 1 makes the cooperation between the various components more closely, which not only improves the airtightness of the cooling space, but also reduces the airflow loss in the cooling space to the greatest extent. The heat dissipation effect is guaranteed, and the overall structure is compact; moreover, the structure is simple to realize...

Abstract

The invention discloses a cooling air channel assembly for a universal gasoline engine. The cooling air channel assembly comprises a fan cover and a flow guide cover. The flow guide cover and the fan cover are matched with each other in an insertion manner and are used for forming cooling air channels for cooling an engine head of the universal gasoline engine. The cooling air channel assembly has the advantages that the flow guide cover and the fan cover are matched with each other in the insertion manner, so that various components can be closely matched with one another, the airtight property of cooling spaces can be improved, air flow loss in the cooling spaces can be reduced to the greatest extent, radiating effects can be guaranteed, and the cooling air channel assembly is compact in integral structure; the cooling air channel assembly with the structure is easy to implement, detach, mount and maintain and convenient to operate, and is changeable.

Description

technical field [0001] The invention relates to the field of forced air-cooled fan cooling, in particular to a cooling air duct assembly 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 cy...
