Benefits of technology

[0009] In aspects of the present invention, a heat exchanger capable of functioning in high temperature and/or pressure environments, with a lower profile cost for the same or better performance than aluminum cast tanks, is provided. In addition, the strength and performance characteristics of lower temperature and/or lower pressure environment plastic tan...

Problems solved by technology

The use of cast aluminum tanks, however, means that such heat exchangers are required to have certain limitations, such as design limitations/need for complex features to provide for dimensional stability and/or part integration; additional manufacturing steps or operations to accomplish outcomes not possible using a casting aluminum process alone; higher costs due to these additional or secondary operations, welding necessary for tanks to the heat exchanger for assembly, high weight, and, in certain cases, inadequate corrosion resistance.
For cast alumin...

Embodiment Construction

[0031] Heat exchanger assemblies, and, especially, heat exchanger assemblies operating in high temperature and / or pressure environments, allow increased temperature and pressures range of application of lower weight and cost tanks. Hybrid tanks, as in the various aspects of the present invention, are therefore useful to replace cast aluminum, or even other metal tanks, such as stamped and brazed aluminum tanks.

[0032] The metal part or parts of the hybrid tank are located in the hybrid tank in at least one, and, more specifically, in a plurality of areas. The metal part or parts, together referred to as the ‘metal shell’, is provided in one strategic area or, in a plurality of areas, or in all of areas necessary to provide the correct rigidity or stiffness for its own particular heat exchanger application, in accordance with the applicable specification. For example, for heat exchanger assemblies comprising a charge air cooler, the metal shell provides stiffness which allows areas o...

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.

Description

FIELD OF THE INVENTION [0001] The present invention relates to heat exchanger assemblies, and, in particular, heat exchanger assemblies that function in high pressure and / or temperature environmental conditions. BACKGROUND OF THE INVENTION [0002] Current tank or tanks for heat exchangers, especially high pressure and / or temperature heat exchangers such as charge air coolers, use materials such as cast aluminum for tanks subjected to high temperatures and / or pressure conditions. [0003] JP2003314287 (A) identifies use of cast Aluminum tanks which are welded to the heat exchanger core. EP1524105 (A2, A3) identifies bonding of two material to form a structural part. [0004] The use of cast aluminum tanks, however, means that such heat exchangers are required to have certain limitations, such as design limitations / need for complex features to provide for dimensional stability and / or part integration; additional manufacturing steps or operations to accomplish outcomes not possible using a ...
