    Abstract: A refrigeration cycle device includes a compressor, a radiator, a first decompression unit, a first evaporator, a second decompression unit, and a second evaporator. A refrigerant joining portion joins refrigerant having passed through the first evaporator and the second evaporator, on a refrigerant suction side of the compressor. The first decompression unit regulates a degree of superheating of the refrigerant between the first evaporator and the refrigerant joining portion on the basis of a first physical quantity having a correlation with the degree of superheating of the refrigerant flowing between the first evaporator and the refrigerant joining portion. The second decompression unit regulates a degree of superheating of the refrigerant between the refrigerant joining portion and the compressor on the basis of a second physical quantity having a correlation with the degree of superheating of the refrigerant flowing between the refrigerant joining portion and the compressor.

    Abstract: A vehicular air conditioner includes a refrigeration cycle system, a high-temperature heat medium circuit, and a low-temperature heat medium circuit. The high-temperature heat medium circuit includes an air-heat medium heat exchanger, a heater core, a branching portion, a common passage, a flow rate adjuster, and an auxiliary heat source. The air-heat medium heat exchanger exchanges heat between the heat medium and an outside air. The heater core is arranged parallel to the air-heat medium heat exchanger and causes the heat medium to transfer heat to a ventilation air. The branching portion divides a flow of the heat medium into a flow toward the air-heat medium heat exchanger and a flow toward the heater core. The auxiliary heat source is arranged in the common passage at a position upstream of the branching portion.

    Abstract: A printed substrate having a first surface to which an electronic component is to be fixed through an underfill material includes a groove that is recessed from the first surface. The first surface includes a pair of lands that is to be electrically connected to the electronic component. The groove extends in a first direction in which the pair of lands extends and is located in a facing region of the first surface in which the first surface is to face the electronic component. An electronic device includes the printed substrate, the electronic component fixed to the first surface and the underfill material disposed between the first surface and the electronic component.

    Abstract: A composite heat exchanger is used in a vapor compression refrigeration cycle. The vapor compression refrigeration cycle includes: a compressor; a decompressor configured to decompress a high-pressure refrigerant discharged from the compressor; and an evaporator configured to evaporate a low-pressure refrigerant decompressed at the decompressor by exchanging heat between the low-pressure refrigerant and a first heat medium. The composite heat exchanger includes a condenser unit, a liquid storage unit temporarily storing a high-pressure liquid refrigerant, a sub-cooler unit sub-cooling the high-pressure liquid refrigerant through heat exchange with a second heat medium, and an internal heat exchanger unit exchanging heat between the high-pressure liquid refrigerant passed through the sub-cooler unit and the low-pressure refrigerant. The condenser unit, the sub-cooler unit and the internal heat exchanger unit are joined together by a predetermined binding element and thereby form an integral structure.

    Abstract: A combined heat exchanger exchanges heat between a refrigerant circulating through a vapor compression type refrigeration cycle, a first heat medium flowing through a first heat medium circuit including a first heat generating element, and a second heat medium flowing through a second heat medium circuit including a second heat generating element. The combined heat exchanger includes a refrigerant flow channel portion through which the refrigerant flows, a first heat medium flow channel portion through which the first heat medium flows, and a second heat medium flow channel portion through which the second heat medium flows. The refrigerant flow channel portion, the first heat medium flow channel portion, and the second heat medium flow channel portion are arranged to transfer heat of the refrigerant to both the first heat medium and the second heat medium.

    Abstract: A combined heat exchanger includes a heat exchange unit having a plurality of plate-like members stacked together. The heat exchange unit includes a heat absorption evaporation unit and an internal heat exchange unit. The heat absorption evaporation unit includes a heat absorption refrigerant passage, and the internal heat exchange unit includes a high pressure refrigerant passage and a low pressure refrigerant passage. The combined heat exchanger has at least one of a high pressure refrigerant outlet port that allows the refrigerant flowing out of the high pressure refrigerant passage to flow out to a cooling refrigerant passage and a low pressure refrigerant inlet port that allows the refrigerant flowing out of the cooling refrigerant passage to flow into the low pressure refrigerant passage.
