Automotive air conditioning system heat exchanger, in particular heating element, for such a motor vehicle air conditioning system and method for operating a heat exchanger of a motor vehicle air conditioning system

摘要

The invention relates to a heat exchanger - device for a motor vehicle - air conditioning system, in particular heating elements - device (1) for a motor vehicle - air conditioning system, which heat exchanger - device (1) a first coolant box (10) and a of this first coolant box (10) spaced second coolant box (12), and a plurality of tubes (14), by means of which the first coolant box (10) and the second coolant box (12) are connected in terms of flow, whereby between these tubes (14) intermediate tubular chambers (42) for a through-flow of air, the coolant tanks (10, 12) with the this coolant tanks (10, 12) which connects in terms of flow tubes (14) for the formation of a in the case of an air flow of the in a first section of the pipe - or pipe / rib block (66) given intermediate tubular chambers (42) and an oppositely directed at the same time for this purpose, the through-flow of air in a second portion of this pipe - or pipe / rib block (66) given intermediate tubular chambers (42) in each case in these two sections according to the pattern - principle are designed acting heat exchanger.
