The invention relates to a heat exchanger for a motor vehicle air conditioning system, in particular a radiator device (1) for a motor vehicle air conditioning system, which heat exchanger (1) exhibits a first coolant box (10) and a second coolant box (12) that is distanced from the first coolant box (10), as well as multiple tubes (14) by means of which the flow between the first coolant box (10) and the second coolant box (12) is connected. Tubing spaces (42) for airflow are formed between these tubes (14), wherein the coolant boxes (10, 12), together with these flow tubes (14) that connect these coolant boxes (10, 12), are arranged so that an airflow can be formed in the tubing spaces (42) in a first section of the tube or tubing rib block (66) and, conversely, at the same time, an airflow can be formed in the tubing spaces (42) in a second section of this tube or tubing rib block (66), in both sections respectively, according to the operative counter-current heat exchange principle.

The invention relates to a device which is used to replace heat, in particular for a motor vehicle, comprising at least one first collecting and/or distribution device for at least one fluidic medium. The collecting and/or distribution device is fludically connected to a plurality of through-flow devices, through which the medium flows at least in parts and the collecting and/or distribution device comprises at least one base device, a covering device and a separating device, which divides the collecting and/or distribution device into at least two partial areas. The base device comprises at least one projection which protrudes in an inward manner from a predetermined plane of the base device in relation to the collecting and/or distribution device and at least one section of the separating device is in contact with at least one lateral side of the projection, and at least one section of the plane of the base device is in indirect contact.

The invention relates to a soldered aluminum heat exchanger, having tubes made of a core material through which tubes a coolant flows, and said tubes being connected to at least one header by means of an inner soldered joint; having a protective plating on the inner face of the core material comprising aluminum and using four-layer technology; having an inner solder plating on the protective plating; and having an outer solder plating on the outer face of the tube facing away from the coolant face.
摘要:
The invention relates to a heat exchanger provided for heating purposes, particularly for a motor vehicle, comprising: a number of parallel pipes, at least one electric heating device (4), which is mounted each time between two adjacent pipes, and comprising a number of fin elements (5) situated between each pair of adjacent pipes and between each heating device (4) and the pipes adjacent thereto. In order to be able to better control the power absorption of the heating devices (4), each heating device (4) comprises two separately controllable heating sections (6, 7). One heating section (6) is placed on one side (8) of the heating device (4) facing one adjacent pipe, whereas the other heating section (7) is placed on an opposite side (9) of the heating device (4) facing the other adjacent pipe.
