Evaporative Hydrophilic Surface For A Heat Exchanger, Method Of Making The Same And Composition Therefor
view source
US Patent:

6568465, May 27, 2003
Filed:

May 7, 2002
Appl. No.:

10/140349
Inventors:

Alan P. Meissner - Franklin WI
Richard G. Parkhill - Racine WI
Assignee:

Modine Manufacturing Company - Racine WI
International Classification:

F28F 1902
US Classification:

165133, 2989003
Abstract:

A heat exchanger/evaporator for transferring heat from a first heat exchange fluid to a liquid to be evaporated into a gaseous second heat exchange fluid that includes a thermally conductive element separating a first flow path for the first heat exchange fluid and a second flow path for the second heat exchange fluid. A first surface is on the element in heat exchange relation with the first flow path and a second surface is on the element opposite the first surface and is in heat exchange relation with the second flow path A hydrophilic coating is bonded on part of the second surface and includes a powder of nominally spherically shaped particles including nickel, chromium, aluminum, cobalt and yttrium oxide bonded together with a braze metal predominantly made up of nickel, chromium and silicon and diffused into the nominally spherically shaped particles and the second surface. Also disclosed is a composition useful in forming a hydrophilic surface and a method of making a heat exchanger/evaporator.

US Patent:

55499279, Aug 27, 1996
Filed:

Mar 1, 1994
Appl. No.:

8/203787
Inventors:

Andrew J. Cottone - Racine WI
Zalman P. Saperstein - Lake Bluff IL
Ronald D. Tait - Franksville WI
Richard G. Parkhill - Racine WI
Jeffrey A. Bahr - Racine WI
Assignee:

Modine Manufacturing Company - Racine WI
International Classification:

B05D 302
B05D 134
US Classification:

427191
Abstract:

Potential difficulties in surface modification of a substrate are avoided by using a mixture that includes a ceramic powder, a brazing material and a flux. Exposure to an elevated temperature activates the flux and at least partially melts the brazing material. Upon cooling, the melt solidifies to bond the ceramic powder to the substrate surface an create the modification.
