Cooling device for under-floor device for vehicle
First Claim
1. A cooling device for an under-floor device that is arranged under a floor of a vehicle and that cools the under-floor device by using a vehicular travel airflow generated by traveling of the vehicle, the device comprising:
- a base plate to a rear surface side of which the under-floor device is attached;
a heat radiating unit that is attached to a front surface side of the base plate and radiates heat conducted from the under-floor device via the base plate;
a cover that surrounds the heat radiating unit and includes a first side surface that is perpendicular to the base plate, a second side surface that is also perpendicular to the base plate and arranged on an opposite side of the cover from the first side surface, and additional surfaces that connect the first side surface to the second side surface, the first side surface includes at least one first side opening capable of causing the vehicular travel airflow to flow into the cover through the first side surface, and the second side surface includes at least one second side opening causing the vehicular travel airflow to flow out from the cover; and
a guide plate positioned to guide the vehicular travel airflow flowing in from the at least one first side opening to the heat radiating unit by blocking at least part of a gap area between at least one of the additional surfaces and the heat radiating unit, the guide plate being provided in a side gap area between the first side surface and the heat radiating unit, and the guide plate being directly attached to the first side surface.

Abstract
A cooling device includes a base plate to a rear surface side of which an under-floor device is attached. A heat radiating unit is attached to a front surface side of the base plate and radiating heat is conducted from the under-floor device via the base plate. A cover surrounding the heat radiating unit and including a side opening is capable of causing traveling wind to flow therein and thereout, in opposite side surfaces facing a traveling direction of a vehicle. A guide plate guides traveling wind flowing in from the side opening to the heat radiating unit by blocking at least part of a gap area between a surface connecting the opposite side surfaces and the heat radiating unit, the guide plate being provided in a side gap area between a side surface of the cover and the heat radiating unit on a traveling-wind flow-in side.
