Abstract

The present invention relates to an aluminum heat exchanger. More particularly, the present invention relates to an aluminum heat exchanger useful for motorized power systems similar to those utilized in the automotive industry for engine heat exchange, including, in particular, radiators. In a preferred method, the flat tubes of the heat exchanger are formed from flat sheet braze material and at least one portion is formed approximately normal to the wide portion (major axis) and parallel to the minor axis of the tube.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to an aluminum heat exchanger. More particularly, the present invention relates to an aluminum heat exchanger useful for motorized power systems similar to those utilized in the automotive industry for engine heat exchange. BACKGROUND OF THE INVENTION

[0002] For a number of years now, industry has been concerned with designing heat exchangers made of various materials, particularly for combustion engines, for both practical and weight reasons. Such materials have included aluminum-based ones such aluminum, aluminum alloy and all-aluminum, in heat exchangers. However, these heat exchangers often have faced the problems of extreme ‘tube side’ or ‘internal’ or ‘coolant’ side pressure drops and manufacturing difficulties that have not been optimally solved or adequately adjusted for in heat exchanger applications.

[0003] Industry has also, more specifically, developed automobile heat exchangers employing such elements as flat t...
