The invention relates to a heat exchanger comprising 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:
A heat exchanger includes a tube with a heat-exchange passage and an end piece. The heat-exchange passage directs the flow of a first medium and includes a first flow section and a second flow section arranged in parallel. The end piece has a tube plate that includes a base plate, a diverter plate, and a cover plate. An end of the tube connects to the base plate. The diverter plate has a cutout that forms a diverter passage. The cover plate lies adjacent to the diverter plate and covers the diverter passage in a fluid-tight manner. A second medium flows exterior to the heat-exchange passage.

The invention relates to a device for exchanging heat, particularly for use in motor-vehicle air-conditioning systems, comprising at least one coolant, at least one collant inlet (3), and at least one coolant outlet (4), which lead into one head pipe (7, 8, 9), whereby the head pipe (7, 8, 9) is divided into at least one inlet section (41′) and into at least one outlet section (42′) by at least one separating element (40). The device for exchanging heat comprises at least one flow-through element (19), which has at least two flow paths situated at least partially parallel to one another, and at least one cross-distrubitor (10′, 10″, 11′, 11″, 12) via which the flow paths of the flow-through element (19) are fluid-connected so that the inlet section is fluid-connected to the outlet section of the head pipe (7, 8, 9).

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 related to a flat tube (1) comprising a return bend section (3), inside of which the flat tube (1) is bent back in such a manner that both planar tube sections (2a, 2b) thereof, which are connect to the return bend section, extend in a longitudinal direction with opposite flow-through directions (4a, 4b) and with longitudinal axes (5a, 5b) that are offset with regard to one another at least in the transverse direction (y). The invention provides that the return bend section (3) is formed in such a manner that a main bending axis (A) extends parallel to the flat tube to be plane and at a predeterminable angle to the tube longitudinal extension, whereby the flat tube plane is determined by the longitudinal and width extension of the flat tube (1).

摘要:
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.
