AI Technical Summary

Technical Problem

Vehicle air conditioning systems face challenges in maintaining an optimal temperature difference between air vents and footwells due to issues with cold air being diverted away from mixing chambers, leading to reduced condensation removal capacity and discomfort, especially in defrost and bi-level modes.

Method used

An air conditioning system with a flow correction element integrated into the mixing flap that redirects cold air towards warm air inlets, ensuring proper mixing without increasing resistance in the airflow channel, and a synchronized mechanism to adjust temperature differences between air vents and footwells.

Benefits of technology

The system achieves effective condensation removal and comfortable temperature distribution by ensuring proper mixing of cold and warm air, maintaining optimal temperature differences without increasing resistance or requiring complex synchronization mechanisms.

Abstract

Air conditioning for vehicles (1A), with: a cold air flow channel (11), a warm air flow channel (12), a mixing chamber (13) in which cold air from the cold air flow duct (11) and warm air from the warm air flow duct (12) are mixed, a cold air opening (111) between the cold air flow channel (11) and the mixing chamber (13), a warm air opening (121) between the warm air flow channel (12) and the mixing chamber (13), a first, second and third opening (161, 171, 181) from the mixing chamber (13), a housing (10) which is equipped with at least the cold air flow duct (11), the warm air flow duct (12), the mixing chamber (13), the cold air opening (111), the warm air opening (121), the first opening (161), the second opening (171) and the third opening (181), a mixing flap (14, 24, 34, 44) positioned near either the cold air opening (111) or the warm air opening (121) or both, and via which the mixing ratio between the cold air and the warm air in the mixing chamber (13) can be determined by moving the mixing flap (14, 24, 34, 44) between a first position in which the flow of cold air from the cold air opening (111) into the mixing chamber (13) is minimized while the flow of warm air from the warm air opening (121) into the mixing chamber (13) is maximized, or a second position in which the flow of warm air from the warm air opening (121) into the mixing chamber (13) is minimized while the flow of cold air from the cold air opening (111) into the mixing chamber (13) is maximized, wherein the mixing flap (14, 24, 34, 44) is movable by a The rotating shaft section is rotatably mounted to switch between the first position and the second position. an air distribution flap (15) which is installed in the mixing chamber (13) or in its lower flow and regulates the flow of air from the mixing chamber (13) to the first, second and third openings (161, 171, 181), a flow correction element (145, 245, 345, 445), which moves with the mixing flap (14, 24, 34, 44), is positioned between the cold air opening (111) and the first opening (161) when the aforementioned mixing flap (14, 24, 34, 44) is moved near the first position, and which directs all or part of the cold air flowing through the aforementioned cold air opening (111) closer to the aforementioned warm air opening (121) than to the aforementioned first opening (161), wherein the flow correction element (145, 245, 345, 445) is configured to direct all or part of the cold air from the cold air opening (111) over one end (145x) of the flow correction element (145, 245, 345, 445), which is located at one end (111a) of the first opening (161) of the cold air opening (111), and over another end (145y) of the flow correction part (145, 245, 345, 445),which is located closer to the rotating shaft section and is directed through the axis of rotation (140x) of the rotating shaft section to the first opening (161).
