The casing includes an upper actuator case and a lower actuator case to accommodate the motor housing therebetween, the casing including a motor support section formed integrally in at least one of the upper actuator case and the lower actuator case to support the drive motor by contacting an outside surface of the motor housing. The motor support section has an elastic contacting member protruding from the at least one of the upper actuator case and the lower actuator case to contact one of an upper slanted surface and a lower slanted surface of the motor housing.
An air conditioner for an automobile includes a foot door (11) and a mixing area. The foot door has a partition wall, and is movable at least between an advanced position where the partition wall reaches a state of blocking an air flow from a merging area to the downstream side in an air passage, and a retreated position where the partition wall retreats from the advanced position in the air passage. The mixing area is provided in the air passage while the partition wall is located in the advanced position, and is designed to cause the air flowing from a cold air passage and the air flowing from a hot air passage into the merging area to mix up more by using the partition wall to block the air flowing from the merging area to the downstream side. Thus, the air conditioner is designed to cause the air to flow into the discharge passage systems via the mixing area.
An automotive air conditioner includes an air-conditioning case in which air passageways having a cold air path via an evaporator, a warm air path via a heater core, and a plurality of discharge path systems communicating with outlets, respectively, are formed. An air mix door distributes cold air and warm air by an opening degree to each of the discharge path systems via a junction region of the cold air and the warm air, and a rotary door having a cross wall is rotatably disposed in the junction region of the cold air and the warm air and blocks air flow from the junction region to the downstream side by the cross wall in an advanced position. The rotary door and the air mix door include an overlap layout which uses a door space inside the cross wall of the rotary door in the advanced position as an opening and closing operation space of the air mix door.
A vehicular air conditioner having an air conditioner case including an air mix area, where a defroster opening, a front seat vent opening, a foot opening, and a back seat vent opening are located on the air conditioner case and configured to open and close the air mix area. A defroster door is configured to open and close the defroster opening. A vent foot switching door is configured to open and close the foot opening and the front seat vent opening selectively. A foot door is configured to open and close the foot opening. A back seat vent door is configured to open and close the back set vent opening. The back seat vent opening is positioned in a vicinity of the foot opening and the back seat vent door and the foot door are downstream from the vent foot switching door.
An evaporator includes a first heat exchanger and a second heat exchanger. The first heat exchanger includes a first path in which coolant flows downwardly, a second path in which the coolant from the first path flows upwardly, and a third path in which the coolant from the second path flows downwardly. The second heat exchanger includes at least two paths including a first path in which the coolant from the first heat exchanger flows upwardly. The number of tubes in the first path of the first heat exchanger is smaller than that in any one of the other paths of the exchangers. The number of tubes in the second path of the first heat exchanger is equal to or greater than that in the third path of the first heat exchanger. The number of tubes in the first path of the second heat exchanger is smaller than that in the third path of the first heat exchanger.
F28D 1/02 - Heat-exchange apparatus having stationary conduit assemblies for one heat-exchange medium only, the media being in contact with different sides of the conduit wall, in which the other heat-exchange medium is a large body of fluid, e.g. domestic or motor car radiators with the heat-exchange conduits immersed in the body of fluid
A connection structure of a multi-channel tube with branching tubes is provided with a multi-channel tube having an end, the multi-channel tube including; an outer tube; a partition being formed in a unitary body and running parallel with the outer tube, the partition partitioning an interior of the outer tube into two or more channel holes; and a passage formed at an end of the partition, the passage linking the channel holes; two or more branching tubes respectively inserted into the channel holes to an insertion depth greater than a depth of the passage measured from the end of the multi-channel tube; and brazing material spreading beyond the passage over clearances between the multi-channel tube and the branching tubes and connecting the multi-channel tube and the branching tubes.
