Abstract: A thermal conductive mechanism for a battery pack made up of a stack of a plurality of sub-battery modules each of which includes a plurality of battery cells arrayed thereon. The sub-battery modules each has opposed major surfaces and are laid to overlap each other in a direction perpendicular to the major surfaces. The thermal conductive mechanism is equipped with plates provided one for each of the sub-battery modules. Each of the plates has a given number of the battery cells disposed thereon and also has heat transfer surfaces extending in a planar direction of the plate. The heat transfer surfaces are placed in one of direct and indirect contact with the given number of the battery cells to achieve transfer of heat therebetween, thereby equalizing the temperature in each of the battery cells and also minimizing a difference in temperature among the battery cells.

Abstract: A vehicle air conditioning system includes: air conditioners provided to respectively correspond to air conditioning zones; and a cooler that cools a target equipment mounted on a vehicle. The cooler includes a cooling circuit through which a heat medium for exchanging heat with the target equipment flows. Of the plurality of air conditioners, the air conditioner that air-conditions a door side zone is a door side air conditioner and the air conditioner that air-conditions a panel side zone is a panel side air conditioner. An amount of heat absorbed from the heat medium during equipment temperature control, in which cooling of the interior and temperature control of the target equipment are respectively performed by the plurality of air conditioners, is smaller in the panel side air conditioner than in the door side air conditioner.

Abstract: An air conditioner for a vehicle includes a refrigeration cycle, a heating unit and a control unit. The refrigeration cycle includes an air-conditioning evaporator, a chilling evaporator, an air-conditioning side flow path, a detour flow path and an air-conditioning flow rate adjustment unit. The control unit includes a determination unit that determines whether a condensation condition is satisfied when a refrigerant is flowing through the chilling evaporator via the detour flow path in a state where an inflow of a refrigerant into the air-conditioning evaporator is prohibited. When the determination unit determines that the condensation condition is satisfied, the control unit controls the air-conditioning flow rate adjustment unit to allow an inflow of a refrigerant into the air-conditioning evaporator as a condensation suppression operation for suppressing condensation of a refrigerant in the air-conditioning evaporator.

Abstract: A battery temperature control device includes a heating medium circuit that connects a battery heat exchanger, an outside air heat exchanger, a heating medium pump, and a flow rate regulating unit. The outside air heat exchanger is connected in parallel to the battery heat exchanger. The flow rate regulating unit adjusts a flow rate of the heating medium in a first path through which the heating medium flows via at least the outside air heat exchanger and a flow rate of the heating medium in a second path through which the heating medium flows by detouring around the outside air heat exchanger. The control unit controls the flow rate regulating unit to adjust a ratio between a flow rate of the heating medium in the first path and a flow rate of the heating medium in the second path.

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.
