An air conditioning device includes a casing that provides multiple air passages, a blower fan that suctions an air from the multiple air passages and blows out the air in the casing, a suction side partitioning member that is disposed on a suction side of the blower fan in the casing and separates air flows from the multiple air passages from each other, and a blowing side partitioning member that is disposed on a blowing side of the blower fan in the casing and separates the air flows from the multiple air passages from each other. The suction side partitioning member and the blowing side partitioning member are disposed so that a relative position of the blowing side partitioning member to the suction side partitioning member is deviated in a rotation direction of the blower fan.

Disclosed therein is a dual zone type air conditioner for a vehicle, which includes: an air volume control door mounted between a blower and an evaporator for controlling the degree of opening of first and second passageways so as to control the volume of air blown to the inside of an air-conditioning case; and bypass passageways disposed in the air volume control door to supply a predetermined air volume to a closed passageway even though the air volume control door is at the location to close the first passageway or the second passageway, thereby preventing a sudden change in air volume by widening a control interval of the air volume control door because the first-stage air volume can be realized even though the air volume control door closes one of the air passageways, and reducing a whistle noise by securing a predetermined cross-sectional area of the air passageway through the bypass passageways even though the cross-sectional area of the air passageway gets narrower while the air volume control door closes one of the air passageways.

An insert is configured to be inserted into a heat exchanger having a plurality of tubes. The insert includes a base and a multiple blades. The blades are extended from the base. At least one of the blades has a spring portion. The spring portion is resiliently deformable and configured to be resiliently inserted between two of the tubes. The spring portion includes two arms. One of the two arms has one thin portion defining one recess dented in one direction in a thickness direction. The other of the two arms has the other thin portion defining the other recess dented in the other direction in the thickness direction. The one thin portion and the other thin portion are resiliently movable in a width direction within a clearance formed by the recesses, while overlapping one another in the thickness direction.

Disclosed is a vehicle air conditioner capable of increasing the aft flow effective region of an inner flow path by reducing the space occupied by support parts of doors for opening/closing a plurality of regions. The vehicle air conditioner comprises: an air-conditioning case in which an air flow path is formed; and a cooling heat exchanger and a heating heat exchanger provided in the air flow path of the air-conditioning case, wherein the air flow path is partitioned and divided into a plurality of regions, and has a plurality of doors for opening/closing each region and a shaft for driving the doors, and the distance between one door and the shaft is different from the distance between another door and the shaft.

An air conditioner for a vehicle includes: an air-conditioning case having therein an air flow passage through which air toward the vehicle interior flows, and an outlet opening formed at an upper part of the air-conditioning case and through which the air toward the vehicle interior passes; a heat exchanger disposed on a lower side of the outlet opening inside the air-conditioning case to exchange heat between air toward the vehicle interior and a heat-exchange medium; and an ion generator that includes electrodes to generate ions. The ion generator is mounted on the air-conditioning case such that the electrodes are exposed in air flowing through the air flow passage. The air-conditioning case has a collision-side wall surface with which the airflow having passed through the heat exchanger collides to be directed upward, and a lateral-side wall surface connected to and laterally adjacent to the collision-side wall surface. The ion generator is disposed at a predetermined position of the collision-side wall surface or the lateral-side wall surface.

The present invention relates to a vehicle air-conditioning system and, more particularly, to a vehicle air-conditioning system in which an air-conditioning module consisting of an air-conditioning case and a blowing apparatus is disposed at a side of an engine room with respect to a dash panel, and a distribution duct for distributing cold and hot air discharged from the air-conditioning case into the inside of a vehicle is disposed on the indoor side of the vehicle with respect to the dash panel. The vehicle air-conditioning system may prevent a reverse flow of outdoor air into a cold air discharge port and a hot air discharge port due to the wind pressure when driving by forming a shielding means at the sides of the cold air discharge port and the hot air discharge port, which discharge the cold and hot air of the air-conditioning case to the outside, thereby improving the cooling and heating performance by smoothly discharging heat through the cold air discharge port and the hot air discharge port.

An air conditioner for a vehicle includes a casing that forms an air passage through which air flows, a blower fan to blow out air, and a heating device to heat air. The casing includes a passage portion through which air flows, a warm air passage that allows air to flow to the heating device, and a bypass passage that allows air to bypass the heating device. A width dimension of the passage portion in a second direction is larger than that of the heating device in the second direction, and is smaller than a height dimension of the passage portion in a first direction.

Vehicle air conditioning apparatus comprising air conditioning case with inlet and outlet, partition wall dividing the inner space into a first and a second space portions; cooling heat exchanger disposed inside the air conditioning case to span the first and second space portions and connected to the outlet; and heat exchanger disposed inside the air conditioning case to span the first and second space portions. The air conditioning case includes a first flow path disposed in the second space portion below the heat exchanger; a channel part disposed behind the heat exchanger, with its entrance communicating with the first flow path, and exit communicating with the first space portion. Accordingly, a portion of air flowing to the first flow path via cooling heat exchanger without passing through heat exchanger is guided to the first space portion via the channel part without being mixed with air passing through heating heat exchanger.

An air conditioning unit for a vehicle has a casing, a heating heat exchanger, a first partition plate, a first opening, a second partition plate, a second opening, and a switching door. The casing has a face opening and a foot opening. The heating heat exchanger is arranged in the casing. The first partition plate partitions a downstream side of the heating heat exchanger in an airflow direction into a first passage and a second passage located below the first passage. The first opening is formed on a downstream side of the first partition plate in an airflow direction and communicates between the first passage and the second passage. The second partition plate is arranged on the downstream side of the heating heat exchanger and is formed with a third passage between the first partition plate and the second partition plate in the first passage. The second opening that is located on a downstream side of the second partition plate in an airflow direction and communicates between an upper side and a lower side of the second partition plate. The switching door opens or closes the first and second openings. The air in the third passage is guided toward the foot opening by the second partition plate and the switching door in an air conditioning mode in which the switching door opens the first opening and closes the second opening.

Disclosed is an air conditioner for a vehicle. The present invention provides an air conditioner for a vehicle capable of introducing indoor air and outdoor air simultaneously or selectively by forming a double-layer flow in an air conditioner case and capable of separately controlling the temperatures of a front seat and a rear seat.
