Inventors:

James A. York - Glendale CA

Assignee:

Smith Engineering Company - South El Monte CA

International Classification:

F28F 500

US Classification:

165 82

Abstract:

A heat exchanger which includes a plurality of elongated, parallel, vertical tubes for directing a hot fluid through a cross flowing fluid, particularly suited for handling larger quantities of fluid which contains abrasives. Each of the continuous tubes are secured at opposite ends to tube sheets. One tube sheet provides vertical support for the tubes, the other tube sheet is allowed to float. The tubes are thus unrestrained in the vertical direction and are permitted to freely expand in the presence of the hot fluid.
