摘要： A rear-side flow passage section (17) includes a rear-side duct (19), a first communication path (21), a second communication path (22), a first damper (23), and a second damper (24). The rear-side duct (19) extends from a downstream side of the heater core (15) to a rear side of a vehicle cabin. The first communication path (21) communicates a downstream side of the evaporator (14) and a front-side flow passage section with each other. The second communication path (22) communicates a downstream side of the evaporator (14) and a downstream side of the heater core (15) with each other. The first damper (23) is configured to allow an airflow to be selectively introduced into the first communication path (21) or the second communication path (22). The second damper (24) is configured to change a communication state between a downstream opening (15b) of the heater core (15), the rear-side duct (19), and the second communication path (22).

摘要： An object of the present invention is to provide a vehicular air conditioning apparatus capable of varying the temperature of air that has passed through a heater core in the up-down direction of the heater core while achieving downsizing. The vehicular air conditioning apparatus includes an electric heater (43) that is provided in a flow channel defined by a housing on the downstream side of an evaporator, that includes heater circuits (48, 49), and that configures a heater core (17) that heats air cooled by the evaporator, and a control device (25) that separately controls the heater circuits (48, 49). The heater circuits (48, 49) are arranged in the up-down direction of the heater core (17).

摘要： The objective of the present invention is to decrease air temperature reduction along an indoor-side surface of a vehicle opening part caused by heat transfer from outside air. A heating device for a vehicle is provided with a heat generating part (2) which is installed on a vehicle component provided along an edge of a vehicle opening part, and which increases, via heat generation, the temperature of low temperature air along an indoor-side surface of the vehicle opening part caused by heat transfer from outside air. The heat generating part (2) may be disposed along an opening part installed with a vehicle window (52), and the heat generating part (2) may include an electric heater that uses electric power as a heat source.

摘要： The purpose of the present invention is to improve the performance of an aspirator. A vehicular air conditioning device (1) includes: a case body; an evaporator (20); a heater core (40); and an aspirator (50) for guiding air in a vehicle cabin to a temperature detection unit. The case body integrally includes a case upstream portion (12) in which the evaporator (20) and the heater core (40) are stored, and a case downstream portion (13) in which the air circulated through the case upstream portion (12) is circulated. The case upstream portion (12) includes a first flow path portion (16a) that circulates the air in a Z-axis direction, and a second flow path portion (16b) that connects to a downstream side of the first flow path portion (16a), and circulates the air in a Y-axis direction. The aspirator (50) includes a primary air introduction portion (53), and is mounted at a central portion of the case body. The primary air introduction portion (53) includes an inlet (53d) formed at an upstream end, and introduces the air in the case body from the inlet (53d). The upstream end of the primary air introduction unit (53) is connected to the second flow path portion (16b) from the Z-axis direction.

摘要： This air-conditioning device (10) for a vehicle comprises a flow path width adjustment portion (14) that is provided at an inlet portion (11BA) of a ventilation flow path (11B) so as to be connected to the inner surface (31a) of a first side wall (31), the flow path width adjustment portion (14) having an upper end connected to a fan mounting portion (35), extending downward, and being located between a third wall (33) and a nose portion (37) in the (Y) direction. The nose portion (37) has an inclined portion (37A) that is inclined with respect to the third wall (33) such that the width of the inlet portion (11BA) increases in the (Z) direction from the inlet to the outlet of the inlet portion (11BA) of the ventilation flow path (11B). In the (Z) direction, the flow path width adjustment portion (14) is formed so as to narrow the width of the inlet portion (11BA) of the ventilation flow path (11B) in the (Y) direction.

摘要： An object is to provide an air conditioning unit and a vehicular air conditioning device that can efficiently distribute conditioned air while preventing an increase in the dimensions of a damper. The air conditioning unit includes a main duct (D1), a subduct (D4) branching from the main duct (D1) and guiding air to a foot outlet port (24), and a second switching damper (30) disposed in the subduct (D4) facing the main duct (D1). The second switching damper (30) includes a rotating shaft (31) and a damper body (32) including a guiding shroud (33) extending in the circumferential direction around the rotating shaft (31). An end flange (34A) at one circumferential end of the damper body (32) protrudes into the main duct (D1) as a result of rotation of the second switching damper (30) around the rotating shaft (31). A radial length (R1) of an end flange (34A) is greater than a radial length (R2) of an end flange (34B) at the other circumferential end of the guiding shroud (33).
