AIR GUIDE STRUCTURE OF RADIATOR IN STRADDLE VEHICLE

摘要

An air guide structure of a radiator built into a straddle vehicle which exchanges heat between a cooling medium of a driving power source and ram air to release heat from the cooling medium. The air guide structure includes an electric fan provided at a core of the radiator such that it is disposed in close proximity to the core at a downstream side in a flow direction of the ram air, and a shroud provided to cover the electric fan from the downstream side and cover the electric fan from above and from both lateral sides, the shroud being open in a downward direction. The core of the radiator is provided with a ram air passage region outside of a portion of the core which is covered with the shroud when viewed in the flow direction of the ram air travelling through the ram air passage region.
