Problems solved by technology

This is an extremely difficult process since the corrugated fin to be inserted into the tube is extremely thin and subject to deformation during the insertion process.
Although these methods have worked well, they suffer from the disadvantage that the stamping process does not have a high production through put.
Another disadvantage is that the stamping process is relatively expensive.

Embodiment Construction

)

[0021] Referring to the drawings and in particular FIG. 1, one embodiment of a heat exchanger 10 for a motor vehicle (not shown), such as a charge air cooler, oil cooler, evaporator, or condenser, is shown. The heat exchanger 10 includes a plurality of generally parallel tubes 12 extending between oppositely disposed headers 14,16. The heat exchanger 10 includes a fluid inlet (not shown) for conducting cooling fluid into the heat exchanger 10 formed in the header 14 and an outlet (not shown) for directing fluid out of the heat exchanger 10 formed in the header 16. The heat exchanger 10 also includes a plurality of convoluted or serpentine fins 18 attached to an exterior of each of the tubes 12. The fins 18 are disposed between each of the tubes 12. The fins 18 serve as a means for conducting heat away from the tubes 12 while providing additional surface area for convective heat transfer by air flowing over the heat exchanger 10. It should be appreciated that the heat exchanger 10 c...

Abstract

A turbulator with offset louvers and method of making the same for a heat exchanger includes a plurality of corrugated fins each having a base extending laterally and longitudinally in a strip. The turbulator also includes a plurality of louvers spaced along the base and extending longitudinally and generally perpendicular to the base in an alternating manner, the louvers being rolled in a direction parallel to a longitudinal axis of the strip.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S)[0001] The present application is a divisional application of co-pending U.S. patent application Ser. No. 09 / 739,950, filed Dec. 18, 2000.[0002] 1. Field of the Invention[0003] The present invention relates generally to heat exchangers for motor vehicles and, more specifically, to a turbulator with offset louvers and method of making same for a heat exchanger in a motor vehicle.[0004] 2. Description of the Related Art[0005] It is known to provide a tube for a heat exchanger such as an oil cooler in a motor vehicle. The tube typically carries a first fluid medium in contact with its interior while a second fluid medium contacts its exterior. Typically, the first fluid medium is oil and the second fluid medium is air. Where a temperature difference exists between the first and second fluid mediums, heat will be transferred between the two via heat conductive walls of the tube.[0006] It is also known to provide corrugated fins or ribs in the int...
