Abstract
This utility model provides an engine compartment hot air exhaust structure and vehicle. When the engine is running, hot air generated in the engine compartment enters the vent pipe through the vents on the wheel arch outer panel, and then flows along the vent pipe to the vents on the side panels. Guided by the vent reinforcement plate, the hot air continues to flow from the side panel vents to the fender vents, and is finally exhausted outside the engine compartment. By setting up sequentially stacked wheel arch outer panels, side panels, and fenders, and opening vents at their respective relative positions, and utilizing the channel formed by the vent pipe and the vent reinforcement plate, efficient exhaust of hot air from the engine compartment is achieved, effectively reducing the temperature inside the engine compartment and improving engine efficiency and service life.
