摘要:
The invention relates to a heat exchanger, particularly a radiator for a heating or air conditioning unit in motor vehicles, which cools a coolant. Said heat exchanger (1) is penetrated by air, comprises collector pipes (S1, S2, S2, S4) and several essentially horizontally disposed pipes (5), and is divided into several partial blocks (T1, T2, T3, T4). The surfaces of the inventive partial blocks are selected according to the dimensions of structural space-related zones having different air temperatures inside the assembly space of the heat exchanger, the partial block which is first penetrated by the coolant being arranged within a structural space-related zone having a higher air temperature, preferably within the zone having the highest air temperature.

The invention relates to a method for forming at least one flat-tube insertion slot in a header tube. A sawcut is introduced into the header tube during a sawing step, and the slot is configured, during a subsequent punching step, by means of a slot punch, which punches into the region of the sawcut. A rimmed opening can be configured during the punching step by using a slot punch with a larger width and/or length relative to the sawcut. The sawcut is preferably introduced to a depth less that the wall thickness of the header tube. The respective web region(s) between chamber of a multi-chamber header tube can be compressed during the punching operation to a level lower than that of a header-tube wall region functioning as a flat-tube insertion stop, in order to form a chamber-connecting duct.

An integrated modular collector—heat exchanger unit for motor vehicle air conditioners and the like has a collector housing in which a collecting space and a heat exchanger unit are disposed. The heat exchanger unit includes two separate heat exchanger ducts which are in a thermal contact. One heat exchanger duct has a helical course and is part of a first flow duct which extends from a housing inlet to a housing outlet in the collector housing. The other heat exchanger duct is part of a second flow duct extending between the collecting space and a housing connection. This other heat exchanger duct also has a helical course, its coils in each case being in a thermal contact with at least one adjoining coil of the first of the first heat exchanger duct.

A heat exchanger, particularly for a heating or air conditioning system for motor vehicles, includes at least one inlet channel and at least one outlet channel and at least one collector, which has at least two metal sheets or plates abutting each other, and a flow device through which a first medium can flow, while a second medium can flow around the flow device. The first medium is distributed by an inlet channel to the collector and to the flow device and can be conducted to an outlet channel, and at least one further channel for distributing the coolant is provided, which is connected in a communicating manner via at least one opening to the inlet channel.

Disclosed is a heat exchanger for motor vehicles, comprising two spaced-apart manifold devices (10, 12) and several connecting tubes (14a, 14b, 16a, 16b). Said connecting tubes (14a, 14b, 16a, 16b) are disposed so as to form two rows of tubes (30a, 30b) which are located next to each other, are penetrated in parallel by the first medium, and are respectively formed by several connecting tubes (14a, 14b, 16a, 16b) that succeed each other in the longitudinal direction (10a, 10b) of the manifold devices (10, 12). The direction of flow of the first medium is deflected at least once between the two manifold devices (10, 12) in each of the rows of tubes (30a, 30b) while the number of changes in the direction of flow between the manifold devices (10, 12) is identical in the rows of tubes (30a, 30b).

Disclosed herein is a heat exchanger with tubes (1) and at least one end piece, which has a tube bottom that, in turn, has a bottom plate (8), a baffle plate (12) and a covering plate (16).
摘要:
The invention relates to an evaporator (1), in particular for an air-conditioning system of a motor vehicle, comprising flow channels for a coolant and ribs which can be impinged upon by air and which are arranged on the outside of the flow channels. According to the invention, at least one cooling element (5) which can be cross-flown by a coolant (5) is connected in a thermally conductive manner to the evaporator (1) and is connected to a secondary circuit (6) which acts as a cooler for the consumers, in particular electronic components (8).
