Abstract:
An aluminum heat exchanger having increased resistance to galvanic corrosion. The exterior of one end of the aluminum tube or connector is coated with a metal or metal alloy. This end is brazed onto a copper or copper alloy inlet or outlet tube. The metal or metal alloy coating inhibits the formation of galvanic corrosion.
Abstract:
A test fixture for testing a flat sample of a material is disclosed. The test fixture having a test vessel for a fluid selected to test the desired properties of the material. The test fixture having a housing with a first end, a second end, and at least one wall extending from the first end to the second end. The housing may have a cylindrical configuration, a parallelpiped configuration, or other geometries. An opening in the housing is provided for receiving the flat test sample such that the assembled housing and the sample form a pressure vessel with an interior chamber.
Abstract:
A heat transfer tube having surface enhancements so as to improve the thermal performance and increase the heat transfer capacity. The heat transfer tube has an inner surface having a layer of sintered, soldered or brazed metal powder thereon.
Abstract:
A heat pipe is formed from two flat plates bonded to each other along the respective peripheries. An inner surface of one or both of the flat plates may have a surface treatment to enhance performance of the resulting heat pipe. A charge of working medium may be disposed in the volume enclosed by the flat plates.
