Abstract: The invention relates to a heat exchanger (1), in particular for a motor vehicle. The heat exchanger (1) includes a plurality of tubular bodies (2) stacked onto one another along a stack direction (S), which in each case delimit a first fluid path (3a) for being flowed through by a refrigerant (K). The individual tubular bodies (2) are arranged along the stack direction (S) spaced apart from one another, so that between intermediate spaces (4) formed between the tubular bodies (2) that are adjacent in the stack direction (S), each form a second fluid path (3b) fluidically separated from the first fluid paths (3a) for being flowed through by air. The individual tubular bodies (2) extend transversely, preferentially perpendicularly to the stack direction (S) along a longitudinal direction (L).

Abstract: The invention relates to a heat exchanger, especially for motor vehicles, comprising a soldered heat exchanger network made of flat pipes (2,3) and corrugated ribs (1). A liquid and/or vaporous-type medium can flow through the flat tubes (2, 3) and air can circulate around the corrugated ribs. One corrugated rib respectively comprises two surfaces (4,5) which are arranged in an essentially parallel manner in relation to each other and which are connected respectively by an arch-shaped piece (6) which is soldered to a flat pipe, said arch-shaped piece comprising three sections (6a,6b,6c) which have different curvatures.

Abstract: The invention relates to a soldered refrigerant condenser that consists of a heat exchange network with flat pipes and corrugated ribs, of collector pipes that fluidically communicate with the flat pipes, and of a collector (10) that is arranged in parallel to one of the collector pipes. Said collector accommodates a dryer and/or a filter (31) and fluidically communicates with the collector pipe via two overflow openings (13, 14). The dryer is configured by a chamber containing a drying agent (28) and limited by a section (18) of the collector (10, 11) and two endplates (23, 24) that extend through the cross-section of the collector (10, 11).

Abstract: The invention relates to a manifold for a cooling agent of an air conditioning plant which comprises a separation form-closed element fixed inside a manifold housing, a heat exchanger provided with said manifold, the closed cooling agent circuit of the air conditioning plant with the manifold and a method for producing said manifold.

Abstract: The invention relates to a cooling agent condenser (1) which comprises a finned tube block (2), collecting tubes (5) arranged on both sides thereof and a manifold (6) which is disposed in a parallel position with respect to the collecting tube (5) and connected to a cooling agent and said collecting tube (5) by means of an overflow opening (8, 9). Said manifold is embodied in the form of a monoblock tube.

Abstract: The invention relates to a heat exchanger (1), especially for motor vehicles, which comprises flat pipes (2) through whose interior a first fluid (FL1) flows and that can be impinged upon externally by a second fluid (FL2). The flat pipes (2) are substantially disposed at an angle to the direction of flow (S2) of the second fluid (FL2) and parallel relative one another and are spaced apart so as to configure flow paths for the second fluid (FL2) that extend through the heat exchanger. Cooling ribs (3) are disposed in the flow paths and extend between respective adjacent flat pipes (2). A plurality of wavy ribs (3) are provided as the cooling ribs. These wavy ribs are disposed one behind the other in the direction of flow (S2) of the second fluid (FL2) and are off-set from one another in the direction of flow (S1) of the first fluid (FL1).

Abstract: The invention relates to for a motor vehicle air conditioning installation, comprising a pipe/rib block, headers which are arranged on both sides thereof and are used to receive the ends of the pipes, and a collector which is arranged parallel to one of the headers, is fluidically connected to the adjacent header via openings, and respectively comprises a closing element and receives a dryer/filter cartridge on the front side, said cartridge being fixed in the header and comprising a peripheral sealant which is arranged between the openings.

Abstract: The invention relates to a heat exchanger, in particular a refrigerant condenser, especially for a motor vehicle air-conditioning unit. The heat exchanger is comprised of a block of tubes and fins and of collecting tubes which are arranged on both sides and receive the ends of the tubes, and of a collector which is arranged parallel to a collecting tube. A method for manufacturing the heat exchanger is also disclosed.
