Abstract: A heating or air conditioning system with a housing and with a heat exchanger located therein, wherein the housing constitutes an upper housing part and a lower housing part in which the heat exchanger is positioned, and the upper housing part forms, in the region where the heat exchanger is positioned, a housing wall that the heat exchanger is in direct contact with. The housing wall is designed to be elastic, at least in sections, such that the housing wall elastically yields in the contact region of the heat exchanger to compensate for dimensional tolerances of the heat exchanger.

Abstract: A motor vehicle air conditioning unit having a housing, a heat exchanger, at least two manifolds and cooling tubes arranged therebetween forming a tube block. The housing has at least one first sealing rib oriented substantially parallel to an extending direction of the at least two manifolds and at least one second sealing rib oriented substantially parallel to an extending direction of the cooling tubes in the tube block, such that the at least one first sealing rib is oriented perpendicular to the at least one second sealing rib.

Abstract: The invention relates to an air-conditioning system, in particular for a motor vehicle, in which a fan takes in air which flows through an evaporator and/or a heater, wherein the fan has arranged downstream of it an air-bypass channel, which contains a bypass damper and guides air past the evaporator. In the case of an air-conditioning system in which the air-mass flow which flows through the air-bypass channel and/or evaporator can be adjusted in a particularly variable manner, an air-throttle element is arranged in and/or on the air-bypass channel and/or upstream or downstream of the evaporator.

Abstract: A fin element for a heat exchanger, in particular for a heating, ventilation, and/or air conditioning system of a motor vehicle, with a plurality of connecting sections and of longitudinal sections, whereby in each case two adjacent longitudinal sections are connected to one another by a connecting section, whereby at least one of the longitudinal sections has gills formed by webs and slots, whereby at least one of the webs has a flared web surface, whereby the web surface is flared out from the at least one longitudinal section, whereby the web surface forms at least two surface sections arranged angled to one another.

Abstract: A motor vehicle air conditioning unit having a housing, a heat exchanger, at least two manifolds and cooling tubes arranged therebetween forming a tube block, the heat exchanger is sealed with respect to bypass air inexpensively and with little technical effort. The housing has at least one V-shaped sealing rib oriented substantially parallel to an imaginary plane spanned by the tube block and/or one H-shaped sealing rib oriented substantially parallel to an imaginary plane spanned by the tube block for sealing a front and/or rear side of the tube block, and the at least one H-shaped sealing rib is oriented substantially perpendicular to the at least one V-shaped sealing rib.
