Abstract: 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.

Abstract: The present teachings provide for a vehicle heating, ventilation, and air conditioning (“HVAC”) assembly including a drive member, a driven member, a connecting member, a guide member, a first door, and a second door. The connecting member can be rotatably coupled to the drive member and the driven member and can be configured to be moved by the drive member to rotate the driven member. The guide member can be in cooperation with the connecting member and configured to restrict movement of the connecting member as the connecting member is moved by the drive member. The first door can be configured to be rotated by the drive member between a first position and a second position. The second door can be configured to be rotated by the driven member between a third position and a fourth position.

Abstract: A heating, ventilation, and air condition (HVAC) unit may include a casing, an evaporator, a heater core, and a first damper. The casing may define a front airflow passageway, a rear airflow passageway having an inlet, and first and second outlets in fluid communication with the rear airflow passageway. The evaporator and the heater core may be disposed within the casing. The first damper may be disposed within the casing between the evaporator and the heater core and movable between a first position in which airflow is directed to the heater core and a second position in which airflow is directed away from the heater core. Airflow across the evaporator from the front airflow passageway to the rear airflow passageway is directed to the first and second outlets when the first damper is moved from the first position toward the second position.

Abstract: A heat exchanger includes multiple tubes, multiple fins, and a partition wall. The multiple fins are stacked alternately with the tubes to form a core including a first section and a second section. The partition wall partitions between the first section and the second section. The first section has multiple drain passages in the vicinity of the partition wall.

Abstract: An HVAC assembly for conditioning air within a vehicle passenger cabin. The assembly includes a housing, at least one front air inlet and at least one front air outlet for conditioning air at a front of the cabin, at least one rear air inlet and at least one rear air outlet for conditioning air at a rear of the cabin, and a heater core. A cover is configured to: be mounted to an exterior of the housing over at least one heater core conduit; direct airflow exiting the housing to the at least one heater core conduit to permit heat transfer from heated coolant flowing through the at least one heater core conduit to the airflow to heat the airflow; and direct the heated airflow out from within the cover towards the at least one rear air inlet to mix with air exiting the at least one rear air inlet.

Abstract: An HVAC airflow door assembly including a pivot hub, a main body, and a flexible member. The pivot hub is connectable with a pivot member for pivoting the door assembly. The main body extends from the pivot hub and includes a distal end opposite to and spaced apart from the pivot hub. The flexible member is mounted to, and extends from, the distal end of the main body, and is configured for connection with a guide track. The door assembly is configured for rotation by the pivot member between a first position in which the flexible member is collapsed, and a second position in which the flexible member is extended relative to the first position.

Abstract: A vehicle cabin air conditioning apparatus including an airflow selecting mechanism movable between a first position to provide a first airflow mode and a second position to provide a second airflow mode. The airflow selecting mechanism restricts first airflow from flowing from a first airflow conduit to a second airflow conduit when in the first position, and permits the first airflow from flowing from the first airflow conduit to the second airflow conduit when in the second position. An electronic control unit is configured to control a first blower based on a user set front cabin airflow level and a second blower based on a user set rear cabin airflow level when in the first airflow mode. The electronic control unit controls the first blower based on the user set front cabin airflow level and the user set rear cabin airflow level when in the second airflow mode.

Abstract: An air-conditioning apparatus for a vehicle cabin has an air-conditioning case defining a plurality of air intake modes. The plurality of air intake modes includes an ambient air intake mode, and a double-layered air intake mode. The double-layered air intake mode supplies ambient air to a front side of the vehicle cabin via a front air passage, and supplies a recirculation air from the vehicle cabin to the rear side of the vehicle cabin via a rear air passage. The controller controls the air-conditioning case to switch the air intake mode from the double-layered air intake mode to the ambient air intake mode, when an evaporator temperature falls below a first threshold value.

Abstract: A vehicle cabin air conditioning apparatus including an airflow selecting mechanism movable between a first position to provide a first airflow mode and a second position to provide a second airflow mode. The airflow selecting mechanism restricts first airflow from flowing from a first airflow conduit to a second airflow conduit when in the first position, and permits the first airflow from flowing from the first airflow conduit to the second airflow conduit when in the second position. An electronic control unit is configured to control a first blower based on a user set front cabin airflow level and a second blower based on a user set rear cabin airflow level when in the first airflow mode. The electronic control unit controls the first blower based on the user set front cabin airflow level and the user set rear cabin airflow level when in the second airflow mode.
