A heat exchanger has tubes, an inlet tank and an outlet tank. The inlet tank and the outlet tank are coupled to ends of the tubes. The inlet tank and the outlet tank have an inlet port and an outlet port, respectively, on ends thereof. The heat exchanger further has a cover member disposed in at least one of the inlet tank and the outlet tank. The cover member partly covers openings of the ends of predetermined tubes of the tubes, the predetermined tubes being closer to at least one of the inlet port and the outlet port.

An air passage flow control device according to the invention includes a plate member having at least one aperture through which air may pass, the degree to which the aperture is exposed being controlled by the positioning of a film member across at least a portion of the aperture. The positioning of the film member relative to the aperture is controlled by rolling and unrolling a portion of the film member on a rotating member that may be selectively moved back and forth across the aperture. By rolling and unrolling the film member to control the opening of the aperture, the present invention avoids relative lateral movement of those portions of the film member that are in contact with the plate member, thereby reducing the frictional forces. Further, the rotating member is configured to reduce the collection of particulate matter on the rotating member and the film member.

A driving apparatus for an air conditioning system has a first and a second electrical actuators for driving air control doors, wherein the first and second actuators are accommodated in a common housing so that they are modularized to each other. The driving apparatus further has a third electrical actuator for driving another air control door, wherein the third actuator is provided at a position separated from the housing. Driving circuits for the first to third actuators are formed on a single IC chip or on a single electrical circuit board. The driving circuits formed on the IC chip or the electrical circuit board is accommodated in the housing for the first and second actuators.

An air passage opening/closing device includes a film member for opening and closing an opening of an air passage of a case. One end of the film member is fixed to a fixing portion on an outer periphery of the opening of the air passage, and the other end thereof is connected to a film winding shaft. A moving member movable by rotation of a drive shaft is provided on the opening, and the film winding shaft is moved while being rotated by the movement of the moving member, so that the film member at the other end side is wound around and unwound from the film winding shaft. Accordingly, when the air passage is opened and closed by the film member, sliding friction can be prevented from being generated between the film member and the case.

An air conditioner includes an air conditioning case for defining an air passage through which air flows into a vehicle compartment, a functional member located in the air conditioning case for performing air conditioning of the vehicle compartment, an outside wall member arranged outside a side wall of the air conditioning case to form a clearance with the side wall, and a coupling part through which the outside wall member is integrated with the side wall. In this air conditioner, the outside wall member is located across approximately a projected line of a central line of the functional member extending in a longitudinal direction of the functional member, projected onto the side wall. Therefore, a vibration of the air conditioning case can be reduced, and a noise generation can be effectively restricted.

In a vehicle air conditioner, first and second downstream side passages are provided in an air conditioning case to guide air to a defroster opening and a foot opening, respectively. A switching door is capable of switching between a partition position for partitioning the first downstream side passage and the second downstream side passage from each other, and a communication position for establishing communication between the first downstream side passage and the second downstream side passage. An air outlet mode switching device is capable of switching between a foot mode and a foot/defroster mode. In the foot mode, the air outlet mode switching device causes both the foot door and defroster door to be opened and causes the first switching door to be set at the partition position. Therefore, it is possible to prevent a problem due to an air outlet mode door with a small opening degree.
摘要:
In a vehicle air conditioner, a flow control member is disposed in an inlet tank of a heating heat exchanger for heating air to be blown into a passenger compartment using a fluid as a heating source. In the heating heat exchanger, a ratio between a first area where the fluid flows, and a second area where the fluid does not flow is changed by controlling an operation position of the flow control member. Thus, a flow ratio between hot air from the first area of the heating heat exchanger and cool air from the second area thereof can be adjusted, so that the temperature of air blown into the passenger compartment can be adjusted.
