Appl. No.:

7/287727

Inventors:

Truett Tyler - Whittier CA
William A. Muller - Fillmore CA
Gregory A. Hart - Hayward CA

Assignee:

Ameron, Inc. - Monterey Park CA

International Classification:

B21C 3704

US Classification:

228146

Abstract:

A welded tapered tube is made by deforming a flat, elongated trapezoidal sheet of metal into an elongated, U-shaped trough in a wagon open at its top and having a U-shaped trough for a bottom. The wagon moves along a track to carry the U-shaped sheet past a series of fin rolls, which deform the U-shaped sheet into an oval-shaped, tapered tube with a seam running the length of the tube. The wagon and tube thereafter move past a welding station where the seam is forged and welded together to form an elongated, tapered tube with an oval-shaped cross section, which may be squeezed between two elongated and semicircular die cavities to form a tapered tube of circular cross section.

Abstract:

An apparatus and method according to one or more embodiments are provided to transfer heat away from various types of thermal sources in flight and/or non-flight systems. Heat transfer may be implemented as a heat exchanger plate that effectively transports heat from a physically secured thermal source to a thermal sink and further to a radiator. In one example, a heat exchanger plate includes a channel extending longitudinally along a surface of the heat exchanger plate and a heat pipe coupled substantially within the channel. A bottom surface and a lateral surface of the heat pipe are thermally bonded to a bottom surface and a lateral surface of the channel, respectively. Additional apparatus and methods are provided.
