Abstract: The present invention relates to an air conditioner for a vehicle. The air conditioner for a vehicle according to the present invention includes: a plate member slidably operating inside an air-conditioning case to control the degree of opening of air outflow ports or air passageways inside the air-conditioning case; a gear shaft for operating the plate member, and separation preventing means formed on rail portions of the plate member interlocking with the gear shaft. According to the present invention, the gear portions of the gear shaft can be smoothly interlocked with the gear holes formed on the rail portions of the plate member and it is prevented that the gear portions of the gear shaft in interlock with the gear holes of the rail portions are separated from the gear holes or mislocated.

Abstract: The present invention relates to an air conditioner for a vehicle that includes: a mode door having a thin. plate member, solidly operating inside an air-conditioning case to control the degree of opening of a defrost vent, a face vent and floor vents, and a gear shaft, engaged with the thin plate member for its operating; and constant discharging means disposed at a rail portion. of the thin plate member and at a guide part of an air-conditioning case overlapped with the rail portion, so that air of a fixed quantity is discharged to side vents of the face vent, thereby providing a simple structure and reducing manufacturing costs because the gear holes of the rail portion and the cut portions of the guide portion serve as the constant discharging means, without a need for additional structure to constantly discharge air toward the side vent.

Abstract: A door for an air conditioner in a vehicle, in which a thin sheet member is joined to a side of a mesh-type frame in such a way as to protrude more than an end portion of the frame so that the protruding portion of the thin sheet member is in contact with the air-conditioning case to thereby promote sealing of the door for opening and closing a passageway of an air-conditioning case, thereby preventing odors caused by molds and reducing material expenses and manufacturing costs by reducing weight of the door.

Abstract: The present invention relates to an air conditioner for a vehicle, which has a mode door of a single plate member including a first door portion that closes at least two vents, a second door portion that closes one vent, and bridge portions that connect the first door portion and the second door portion with each other, thereby opening and closing a plurality of vents by the single mode door, reducing the number of components, weight and manufacturing costs by simplifying the entire structure of the mode door because it uses the single plate member, reducing the size of the air conditioner, preventing bad smells caused by inhabitation of molds and being reusable due to the use of the single plate member, and preventing the door from being caught because the plate member has bent portions formed at end portions thereof.

Abstract: The present invention relates to a center mounting type air conditioner for a vehicle, which can reduce size and noise of a blower, and enhance installation efficiency and reduce an installation space of the air conditioner installed in the vehicle. At least one bypass passageway is formed in a dead space located between the scroll case and the air conditioning case, whereby some of air sucked from the intake duct is bypassed and sucked toward the second wheel of the dual blower wheel, to which the motor is connected.

Abstract: The present invention relates to a heat exchanger, which can independently controls the volume of heat exchange medium flowing through tubes of a left heat exchange part and a right heat exchange part to independently control the temperature of a driver's seat and a passenger's seat, thereby realizing a compact structure since a temp door for controlling temperature is omitted from an air-conditioning system for the vehicle, which can reduce an operating force and increase durability since heat exchange medium controlling means are in a rotational structure, and which can minimize a temperature difference between the right and left sides thereof since the heat exchange medium is distributed to the tubes uniformly.

Abstract: The present invention relates to a blower for air conditioner of automotive vehicles capable of striving to increase the blowing volume and reduce noise, and simplifying the structure of the blower by distributing the air come into the inside of an intake duct effectively to an upper blowing wheel and a lower blowing wheel.

Abstract: The present invention relates to a door for an air conditioner in a vehicle, which includes a sheet member adapted to surround a door body, joining means for fixing both end portions of the sheet member to the door body, and support portions protrudingly formed on sides of the door body to form sheet member buffering spaces, thereby reducing material expenses and the entire manufacturing costs by reducing weight of the door, preventing a bad smell generated by inhabitation of molds by using the sheet member, preventing noise generated when the door is operated, and easily fixing the sheet member through a simple structure.

Abstract: The present invention relates to a heat exchanger which can suitably regulate the quantity, the feeding position or the feeding order of heat exchange medium fed into tubes to adjust heat exchange performance according to cooling and heating load. The heat exchanger comprises a plurality of tubes placed at least one header, each tube having both ends fixed to the header, medium-distributing means installed at the header for feeding heat exchange medium to the specific tubes, a tank placed over the medium-distributing means, the tank having a medium-inlet pipe, a medium-outlet pipe and distribution passages for feeding heat exchange medium to specific regions of the medium-distributing means, and medium-regulating means installed at the tank and operated in response to a control signal for adjusting the feed of the heat exchange medium.
