A header for a heat exchanger includes a substantially planar base portion and a pair of step portions. The step portions are angled from the plane of the base portion. The header is also provided with a plurality of substantially parallel slots spaced apart along the length of the header. Each slot has an elongate section extending across the width of the base portion and end sections extending from the elongate section into the step portions of the header.

Header for heat exchanger

A heat transfer tube for a heat exchanger and a method of manufacturing such a tube. The heat transfer tube includes opposing top and bottom walls and end walls connecting the top and bottom walls to each other. The top and bottom walls each define a substantially planar surface and the end walls each define a generally curved surface. The end walls each including deformations formed therein to strengthen the heat transfer tube.

A heat exchanger includes a first section and a second section for cooling distinct fluids, wherein the second section is adapted for cooling oil. The heat exchanger includes first and second manifolds divided by baffles into first and second chambers. A plurality of tubes connect the manifolds in fluid communication with the first chambers to form the first section of the heat exchanger. A plurality of oil cooling tubes connect the manifolds in fluid communication with the second chambers to form the second section. The oil cooling tubes have a cross-section characterized by a performance ratio between about 3.9 and 8.5 wherein the performance ratio is the ratio of the wetted perimeter in millimeters divided by the cross-sectional area of tube metal in square millimeters. The oil cooling tubes may be formed of extruded metal with internal fins or an extruded tube having a stamped metal insert.

Automotive heat exchanger

A heat exchanger for a vehicle is provided, where the heat exchanger includes core having first, and second sets of flow tubes extending between first and second headers and defining separate flow paths. One of the headers includes a first portion in fluid communication with the first set of flow tubes and a second portion defining a receiver/dryer chamber that is in fluid communication with the second set of flow tubes. A dryer is located within the receiver/dryer chamber.

Integrated condenser oil cooler with a receiver/dryer

An apparatus is disclosed for supporting and sealing a heat exchanger unit. Specifically, a unitary header and tank unit is disclosed comprising a condenser header and tank unit arranged in parallel relation to a radiator header and tank unit. The unitary header and tank unit is formed from a single piece of stamped material. The single piece of material is stamped to include a perpendicular extrusion and two base portions, each base portion being perforated. The partial separation of the perpendicular extrusion into two flange portions allows the base portions to be folded over onto the flange portions thereby forming two header and tank units with a single internal partition. Additionally, a fin unit is disclosed that is capable of traversing the heat exchange fins of multiple heat exchangers.

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.

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.

A folded 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 folded tube includes at least one of the base and the top having at least one internal web having an initial web height and being compressed to extend the at least one internal web to a final web height greater than the initial web height and defining a plurality of fluid ports.

Folded tube for a heat exchanger and method of making same

A heat exchanging device is disclosed. The device includes a fluid flow tube having a turbulator which includes a plurality of coil sections. Each of the coil sections includes a number of coil members of uniform diameter. The coil sections are spaced apart by a predetermined number of other coil members having smaller diameters and different heights than the coil members in the coil sections. These coil configurations force fluid flowing around them into heat exchanging contact with the tube walls.
