Embodiment Construction

[0024] As shown in the figure: the ventilator with a close-fitting windshield in this embodiment of this embodiment includes a fan casing 3 and a penetrating airtight air passage closely attached to the edge of the fan casing in the circumferential direction for cooling the ventilator The wind guide cover assembly; the structure of the present invention is suitable for forced air cooling ventilation machines, wherein the fan cover 3 is used to cover the impeller, and the fan cover 3 and the wind guide cover assembly are used to form the casing 1 (crankcase) of the ventilation machine The air duct for cooling with the cylinder head 2. In this embodiment, the fan cover 3 is approximately circular in structure, and its rear end surface is an irregular edge structure. The airtightness of the internal cooling space is high by means of close fit, preventing the loss of cooling airflow, so as to achieve the purpose of ensuring the heat dissipation effect; in addition, the general mach...

Abstract

The invention discloses an outer cover component for a forced cooling ventilator. The outer cover component for the forced cooling ventilator comprises a fan cover and an air director component which is tightly adhered to the circumferential edge of the fan cover to form a through airtight air channel for cooling air circulation; because the air director component is tightly adhered to the circumferential edge of the fan cover to form the airtight through cooling space, the leakproofness of the whole cooling space is greatly improved, and the airflow loss in the cooling space is reduced so as to ensure the cooling effect; in addition, because of the airtight adhering structure of the fan cover and the air director component, the whole structure is more compact, and the space is saved.

Description

technical field [0001] The invention relates to the cooling field of forced air-cooled ventilation machines, in particular to an outer cover assembly for forced air-cooled ventilation machines. 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 o...
