To provide an engine room heat exhaust structure that can accelerate heat-exhaust in an engine room and prevent air resistance from increasing during travelling of a vehicle.SOLUTION: An engine room heat exhaust structure, which exhausts heat from an engine room, comprises: the engine room that stores an engine in which cylinder rows are arranged in a longitudinal direction of a vehicle; a wheel house that is provided outside in a vehicle width direction of the engine room; an exhaust purification device that is arranged between the engine and the wheel house; a splash shield that shields infiltration of water from the wheel house into the engine room; a wheel house liner that protects the inner wall of the wheel house; an ejection part that is provided at a site closer to a rear side than the exhaust purification device of the splash shield, in order to eject some of air for cooling having cooled the exhaust purification device into the wheel house; and a guiding part in the wheel house liner that guides the air for cooling ejected into the wheel house to below the vehicle, behind the wheel house.SELECTED DRAWING: Figure 1

    【課題】エンジンルームの排熱を促進させ、且つ車両走行時の空気抵抗の増大を抑制することができるエンジンルーム排熱構造を提供すること。【解決手段】エンジンルームからの排熱を行うエンジンルーム排熱構造は、車両の前後方向に気筒列が並んだエンジンが収容されたエンジンルームと、エンジンルームの車幅方向外側に設けられたホイールハウスと、エンジンとホイールハウスの間に配設された排気浄化装置と、ホイールハウスからエンジンルームへの水の侵入を遮断するスプラッシュシールドと、ホイールハウスの内壁を保護するホイールハウスライナを備え、排気浄化装置を冷却した冷却用空気の一部をホイールハウス内に排出するために、スプラッシュシールドの排気浄化装置よりも後方の部位に設けられた排出部と、ホイールハウス内に排出された冷却用空気をホイールハウス後方において車両の下側に案内するために、ホイールハウスライナに案内部を有する。【選択図】図1
