Patent number: 6622517
Abstract: A condenser assembly for a vehicle air conditioning system. The condenser assembly includes a core comprised of a plurality of parallel tubes between which are located a plurality of fins. A pair of headers are located on opposite ends and in fluid communication with the tubes of the core. The headers are constructed such that their primary components exhibit constant cross sectional profiles along their lengths. This enables the volumetrics of the condenser assembly to be altered with a minimal amount of tooling change over being required.

Patent number: 6612031
Abstract: A tube and method of making the same for a heat exchanger includes a base, a top spaced from and opposing the base, a first side interposed between the base and the top along one side thereof, and a second side interposed between the base and the top along another side thereof. The tube includes an end form formed solely on either one of the first side and the second side to create a stop for inserting said tube into a manifold of the heat exchanger.

Patent number: 6453711
Abstract: A tube and turbulator and method of making the same for a heat exchanger including a base, a top spaced from and opposing the base, a first side interposed between the base and the top along one side thereof, and a second side interposed between the base and the top along another side thereof. The base, top, first side and second side form a channel. The second side is triple hemmed such that ends of the base and the top are disposed within the channel. A flat turbulator may be disposed inside the tube and includes a base extending laterally and longitudinally in a strip. The flat turbulator also includes a plurality of corrugations spaced laterally along the base and extending longitudinally and generally perpendicular to the base in an alternating manner. The corrugations are rolled in a direction parallel to a longitudinal axis of the strip.

Patent number: 6360560
Abstract: A condenser includes a plurality of generally U-shaped fluid carrying tubes having free ends and a manifold matingly engaging the free ends of the tubes and having an interior chamber. The manifold includes a receiver dryer disposed in the interior chamber and having a first fluid conduit wall and a second conduit wall extending axially to form a generally parallel first fluid passageway and second fluid passageway in fluid communication with the tubes and a dryer capsule being disposed in the interior chamber to dry fluid in the manifold.

Patent number: 5934365
Abstract: A heat exchanger having a plurality of elongated, generally flat tubes is disclosed, each tube including a planar base, a top, and pair of arcuate opposed side portions interposed between the base and the top is disclosed. A partition extends from the top to the base to define a pair of fluid passageways, the partition including a pair of opposing, contacting shoulder portions and a leg portion depending from each of the shoulder portions which contact the base. A first braze receiving of predetermined size is defined between the shoulder portions and the manifold of the heat exchanger. The size of the braze receiving area is controlled by minimizing the curvature of the shoulder portions.
