Title:
ENGINE COOLING DEVICE
Document Type and Number:
Japanese Patent JP2005233190
Kind Code:
A
Abstract:
To appropriately prevent clogging of a dust-proof net while cooling an engine by a fan.
In this engine cooling device, the fan 16 is constituted so as to be switchable between a cooling state where wind is generated so as to pass through the dust-proof net in an engine cooling direction along with the rotation of the fan 16 and a dust removing state where wind is generated so as to pass through the dust-proof net in a direction reverse to that in the cooling state along with the rotation of the fan 16. A space between the dust-proof net and the fan 16 in the dust removing state is made narrower than that in the cooling state.
