Abstract: An air conditioner is configured to be switchable between a heating mode and a cooling mode. In the cooling mode, a high-temperature heat medium circulates between a high-pressure side refrigerant-heat medium heat exchanger and a high-temperature heat medium-outside air heat exchanger in a state where a refrigerant circulates in an air-cooling heat exchanger. In the heating mode, the high-temperature heat medium circulates between the high-pressure side refrigerant-heat medium heat exchanger and an air-heating heat exchanger, while a low-temperature heat medium circulates between a low-pressure side refrigerant-heat medium heat exchanger and a low-temperature heat medium-outside air heat exchanger, in a state where the refrigerant circulates in the low-pressure side refrigerant-heat medium heat exchanger.

Abstract: A refrigeration cycle device includes a compressor, a heater device, a high-stage side decompressor, a gas-liquid separator, a refrigerant branch portion, a first decompressor, a first evaporator, a second decompressor, and a second evaporator. The compressor has an intermediate pressure port through which an intermediate-pressure refrigerant flows into the compressor. The gas-liquid separator is configured to separate the intermediate-pressure refrigerant into a gas refrigerant and a liquid refrigerant. The refrigerant branch portion is configured to divide a flow of the liquid refrigerant separated by the gas-liquid separator. In a cooling mode for cooling a heat exchange target fluid, a refrigerant circuit is switched such that a low-pressure refrigerant flows from the branch portion to the first evaporator. In a heating mode for heating the heat exchange target fluid, the refrigerant circuit is switched such that the low-pressure refrigerant flows from the branch portion to the second evaporator.

Abstract: A device temperature controller includes a heat absorber that absorbs heat from a temperature control target device to evaporate working fluid in liquid phase, and a condenser disposed above the heat absorber to condense the working fluid which has been evaporated into gas phase at the heat absorber. The device temperature controller includes a gas passage portion that guides the working fluid which has been evaporated into gas phase at the heat absorber to the condenser, and a liquid passage portion that guides the working fluid which has been condensed into liquid phase at the condenser to the heat absorber. At least a part of the gas passage portion and at least a part of the liquid passage portion are in contact with each other.

Abstract: A device temperature adjusting apparatus in which working fluid circulates is mounted on a vehicle and controls a temperature of a target device. The device temperature adjusting apparatus includes a heat absorbing portion that evaporates the working fluid by causing the working fluid to absorb heat from the target device, and a heat releasing portion condenses the working fluid by causing heat release from the working fluid. The device temperature adjusting apparatus includes a forward path portion that defines a forward flow passage and a return path portion. The heat releasing portion is disposed in an inside air circulation path through which inside air circulates while vehicle interior air conditioning is performed by an air conditioning unit that blows out temperature-controlled air to an interior of the vehicle.

Abstract: This electronic device includes a metallic casing that accommodates a component and a circuit board in respective spaces separated by a partition wall, and a metallic cover for protecting the circuit board by covering the casing. The cover has a protruding portion protruding toward the accommodating space for accommodating the circuit board, and the casing has a receiving portion to which the protruding portion is fitted at a position corresponding to the protruding portion. The cover has a deformation suppressing portion formed so that a bending rigidity with respect to a bending which is bent with a forming position of the protruding portion as a fulcrum and is directed to a protruding direction of the protruding portion as a fulcrum is greater than a bending rigidity in planar structure in a facing surface opposed to the circuit board.

Abstract: A vehicular heat management device includes a first heat source, a second heat source, a heater core, a first heat medium pathway, a second heat medium pathway, a heater core pathway, a switching portion, and a control unit. The first heat source is provided in the first heat medium pathway, and the second heat source is provided in the second heat medium pathway. The heater core is provided in the heater core pathway. The switching portion switches between flowing connection and flowing disconnection. The control unit performs at least one of a switching control and a second heat source control when a temperature of the heat medium of the heater core pathway is at or above a predetermined temperature. In the switching control, the switching portion connects the second heat medium pathway to the heater core pathway. In the second heat source control, the second heat source generates heat.
