A battery provided in a vehicle and configured to supply electric power is cooled down by coolant the heat of which is exchanged with the heat of external air by a radiator. The radiator is provided near the battery and performs heat-exchange between the coolant and the external air taken in through introduction holes provided on a bottom face of the vehicle. Thus, even in a case where the radiator is provided in a vehicle floor portion so that the battery is upsized, it is possible to restrain a coolant pipe from being elongated. This accordingly makes it possible to improve mountability to the vehicle.

Vehicle cooling structure

A vehicle heat management device that includes: a pump that circulates cooling water around a cooling water circulation path; an air blower that blows air through a radiator toward an exterior heat exchanger of an air-conditioning device of a vehicle; and a de-icing controller that, in a case in which an estimated ice adhesion amount on the exterior heat exchanger is a predetermined value or greater, starts first de-icing control by using a pump to circulate cooling water in a flow path including a second flow path, in the state in which a first flow path and the second flow path are isolated from each other by a first switching section, and using the air blower to blow air through the radiator toward the exterior heat exchanger.

Vehicle heat management device

A bumper reinforcement structure capable of achieving a weight reduction while still securing required bending strength in a bumper reinforcement structure with closed cross-section structure configured by joining together an inside member and an outside member. A bumper reinforcement is formed with two closed cross-sections configured by joining together three top-to-bottom flanges of an inner panel to three top-to-bottom flanges of an outer panel. The flanges of the inner panel are disposed in the same front-rear direction position as that of the wall portions that configure the closed cross-sections.

Bumper reinforcement structure

A vehicle end section structure capable of securing coupling rigidity at a coupling section between bumper reinforcement and a framework member where a hook attachment section is provided. The vehicle front section structure includes bumper reinforcement of B-shaped cross-section formed with a rearwards opening indented portion between a top and bottom pair of closed cross-sections, a crush box disposed at the rear of one length direction end portion of the bumper reinforcement, bolts and weld nuts for joining the bumper reinforcement at the top-bottom closed cross-sections to locations inside the closed cross-section of the crush box as viewed along the front-rear direction, and a pipe nut that is disposed in an indented portion facing an access hole to enable access to a hook member through the access hole and that is fixed to the crush box inside the closed cross-section of the crush box as viewed along the front-rear direction.
