Abstract: A cooling device includes: an evaporator configured to cool a battery pack by evaporating a heat medium by heat exchange between the battery pack and the heat medium, the battery pack including a plurality of battery cells arranged in an arrangement direction; a condenser disposed above the evaporator and configured to radiate heat of the heat medium to an external fluid by condensing the heat medium by heat exchange between the heat medium and the external fluid; a gas-phase passage configured to guide the heat medium in a gas phase from the evaporator to the condenser; and a liquid-phase passage configured to guide the heat medium in a liquid phase from the condenser to the evaporator, wherein a cooling amount at an end of the evaporator in the arrangement direction is lower than a cooling amount at a center of the evaporator in the arrangement direction.

Abstract: A thermal management system for a vehicle includes a switching power supply device, an electronic member configured to output an electrical power adjusted by the switching power supply device, and a control device configured to control operation of the switching power supply device. When the control device receives a heating request from at least one of devices that include a drive device used for driving the vehicle and an air conditioning device used for performing an air conditioning in a vehicle compartment, the control device causes the switching power supply device to be operated in a heat increasing operation in which heat generated from the electronic member is increased more than that in a general operation state, and supplies the generated heat to the at least one of the drive device and the air conditioning device.
