Abstract: A heat exchange system and method for use with a combo-cooler heat exchanger as shown. In one embodiment, a combination of a heat exchanger module with a combo-cooler heat exchanger and a fan shroud is disclosed wherein the fan shroud covers approximately one-hundred percent of the condenser of the combo-cooler heat exchanger and leaves portions of the fluid coolers of the combo-cooler open to ram airflow.

Abstract: A support system for a cooling fan for a heat exchanger. A suspension system supports an inner hub inside an outer support structure. The inner hub or ring supports the fan and motor. The suspension system includes an array of spiral support arms, extending from the inner hub to the outer supports. These arms have both spanwise and chordwise camber. The particular suspension system increases natural frequencies of the support system, over that wherein purely radial arms connect the inner hub and outer supports.

Abstract: Heat exchanger assemblies, and, in particular, heat exchanger assemblies that function in high pressure and/or temperature environmental conditions, are described. An essential feature of the heat exchanger assembly is the presence of an hybrid tank comprising both plastic or plastic like materials and metal or metal alloy materials, that provides for good structural integrity and operation of the assembly under high pressure and/or temperature conditions.

Abstract: There is disclosed an attachment (12) suitable for attaching a first component of an article to a second component of the article. The attachment preferably includes a flange portion (20) extending from the first component and one, but preferably, a pair of flange members (22) extending from the second component. The flange portion (12) and the flange members (22) typically interferingly engage one another for attaching the first component to the second component. It has been found that the attachment provided in the present invention is particularly effective for attaching a heat exchanger (14) to another component such as a shroud or another heat exchanger (16) together for forming a heat exchanger assembly (10).

Abstract: A cooling fan for a vehicle. Many engine compartments of motor vehicles are small in size, and contain numerous components. Electric cooling fans are used to draw air through a radiator. Given the cramped conditions within the engine compartment, the exhaust of the fan cannot be directed into open air, but must impinge on one or more of the components within the compartment. This situation reduces velocity in the exhaust, and also reduces efficiency of the fan. The invention provides a collection of generally co-axial stators which divert the exhaust around the components, while retaining much of the velocity of the exhaust.

Abstract: A cooling fan for an engine in a vehicle. Ordinarily, a fan rotates within a shroud, which surrounds the fan. Leakage can occur between the tips of the fan blades and the shroud, wherein fan exhaust moves forward, and then passes through the fan again. The invention reduces leakage by placing a surface downstream of the fan. The surface employs the Coanda Effect, to urge fan exhaust to continue in the downstream direction, and not move forward as leakage air.

Abstract: A two-fold combo cooler comprising non gas cooler and gas cooler portions, is provided, particularly for use in an assembly. An assembly having a gas combo-cooler has been found especially useful in automotive applications.

Abstract: Isolator assemblies and isolators between separate parts or components, and, particularly, multi stage isolators, especially, isolators useful in automotive applications are described. The isolators have a tubular cross section, made of the same material as the isolator body, which can flex when in a deflection stage, or can compress in a compression stage, thus allowing for reduced wear and/or longer life for both the isolator and the parts and components separated thereby.

Abstract: Automotive heat exchanger assemblies that can withstand high environmental temperature and pressures conditions are described. By providing for a strengthened fin in contact with the tubes at the areas of highest stress, the heat exchanger assembly is strengthened to be efficient under actual operating conditions.

Abstract: The present invention relates to components which provide an isolation or sealing function at joints or interfaces, said component being comprised of a semi-rigid or flexible material, wherein the flexible material is provided with a surface coating in at least one area.

Abstract: Isolator assemblies and isolators between separate parts or components, and, particularly, multi stage isolators, especially, isolators useful in automotive applications are described. The isolators have non perpendicular ribs, made of the same material as the isolator body, which can flex when in a deflection phase or stage, or can compress in a compression phase or stage, thus allowing for reduced wear and/or longer life for both the isolator and the parts and components separated thereby.

Abstract: Isolator assemblies and isolators between separate parts or components, and, particularly, multi stage isolators, especially, isolators useful in automotive applications are described. The isolators have a conical cross section, made of the same material as the isolator body, which can flex when in a deflection stage, or can compress in a compression stage, thus allowing for reduced vibration transmission and/or wear or longer life for both the isolator and the parts and components separated thereby.

Abstract: The present invention relates to the field of automotive heat exchangers, and, in particular, to ribbed heat exchanger tanks. This invention uses ribs that are oriented perpendicular to the local wall bending axes, and, therefore, not necessarily perpendicular to or parallel with the plane of the header to improve resistance to thereby reduce wall deflection and reduce stress concentration in or near the ribs.

Abstract: The present invention relates to heat exchangers, and in particular, combo-cooler heat exchange having manifolds, tubes in fluid communication with manifold, and fins, and at least one controlling device in the manifold or manifolds that controls, via pressure or temperature differences, the flow of fluids through the controlling device. By controlling or modulating mass flow rate of heat exchanger fluids, such as refrigerants, in certain condenser tubes, combo-cooler, and, specifically, condenser element performance, is positively improved when improved performance is most needed in the motor vehicle.
