The first refrigerant flow path includes a first branch portion, a first converging portion, and a plurality of first branch flow paths connecting the first branch portion and the first converging portion, and the second refrigerant flow path includes a second branch portion, a second converging portion, and a plurality of second branch flow paths connecting the second branch portion and the second converging portion.

Abstract: In a vehicle seat air-conditioning device, at least a first inlet, a second inlet, and an outlet are provided in a seat, and at least a first ventilation path, a portion of a second ventilation path, a ventilation path selection switch, a blower, and a third ventilation path are provided inside of the seat. To lead air to the third ventilation path, the ventilation path selection switch has: a first mode in which the first ventilation path is connected to the third ventilation path; a second mode in which the second ventilation path is connected to the third ventilation path; and a third mode in which the first ventilation path and the second ventilation path are connected to the third ventilation path. A controller switches between the modes of the ventilation path selection switch by selecting one of the first mode, the second mode, or the third mode.

Abstract: A seat air-conditioning device includes: a blower; a first ventilation path through which air is drawn in by the blower from a first inlet in a seat base of a seat on which a person sits; a second ventilation path through which the drawn air is discharged from a first outlet in the seat; a third ventilation path that is different from the second ventilation path and through which the drawn air is discharged from a second outlet in the seat; and an outlet ventilation path selection switch that is between the blower and the first and second outlets and selects at least one of the second and third ventilation path to which the drawn air is to be led. The first inlet is vertically below the first outlet and the second outlet.

Abstract: A battery pack includes a battery module group including a plurality of battery modules, a coolant layer configured to allow a coolant to circulate, and a refrigerant layer configured to allow a refrigerant to circulate. The coolant layer includes a first surface and a second surface opposite to the first surface. The refrigerant layer includes a third surface and a fourth surface opposite to the third surface. The first surface of the coolant layer is closer to the battery module group than the second surface of the coolant layer. The third surface of the refrigerant layer is closer to the battery module group than the fourth surface of the refrigerant layer. The battery module group is arranged along the first surface of the coolant layer. At least part of the coolant layer is arranged between the refrigerant layer and the battery module group in a plan view.

Abstract: A vehicle includes a first heat exchanger plate and a second heat exchanger plate. The first heat exchanger plate includes a first coolant layer in which a coolant flows and a refrigerant layer in which a refrigerant flows, and the second heat exchanger plate includes a second coolant layer in which the coolant flows. The first coolant layer and the second coolant layer are connected to each other via a coolant layer connection passage.

Abstract: A vehicle air conditioner includes an evaporator configured to cool air, a heater core provided on a downstream side of the evaporator, a plurality of doors provided between the evaporator and the heater core, and a central air path formed on the downstream side of the evaporator. The central air path is provided with a first door of the plurality of doors, and a first side air path formed on a first side of the central air path. The central air path is further provided with a second door of the plurality of doors, a second side air path formed on a second side of the central air path, and a third door of the plurality of doors. A sub-casing is configured to form the central air path, and a first division casing and a second division casing are configured to sandwich the sub-casing.

Abstract: A mix door structure has drive force for opening and closing a slide door part of a middle slide door unit among multiple slide door units arranged side by side transmitted by an input shaft. The input shaft includes an inner input shaft part (input gear and inner input shaft) which is rotationally supported on two sides at both end portions thereof on bearings provided to a pair of door attachment wall parts of the middle slide door unit and an outer input shaft part (outer input shaft and rotary member) which is rotationally supported on one side on a first shaft hole provided in an outer door attachment wall part of an outermost slide door unit. The inner and outer input shaft parts are coupled to each other through a coupling hole in the inner input shaft part.

Abstract: A mix door includes a slide door unit, a slide driving part configured to drive the slide door unit, and a gear cover partially covering the slide driving part. The slide driving part includes a gear mechanism portion formed of a rack portion and a gear portion. The gear cover is provided to cover the gear portion.

Abstract: A non-contact charging method, in which a battery-powered device is set down on a charging platform, a power receiving coil in the battery-powered device is electromagnetically coupled to a power transmission coil in the charging platform, power is transmitted from the power transmission coil to the power receiving coil by electromagnetic induction, and a battery (52) in the battery-powered device is charged. The charging current of the battery is detected on the battery-powered device side, the transmission efficiency is detected from the detected charging current, the detected transmission efficiency is compared to an efficiency threshold value, it is determined that a foreign object is on the charging platform when the detected charging efficiency is less than the efficiency threshold value and it is determined that a foreign object is not on the charging platform when the detected charging efficiency is greater than the efficiency threshold value.
