US Patent:

8608696, Dec 17, 2013

Filed:

Feb 24, 2010

Appl. No.:

12/711749

Inventors:

Andrew J. DiMeo - Raleigh NC, US
Nathan M. Cox - Raleigh NC, US
Steven P. Grove - Mooresville NC, US
Samuel Lee - Raleigh NC, US
Luke D. Oltmans - Raleigh NC, US
Kathryn H. Sauer - Raleigh NC, US

Assignee:

North Carolina State University - Raleigh NC

International Classification:

A61F 7/12

US Classification:

604113

Abstract:

A cooling device includes a target fluid inlet, a target fluid outlet, an inner conduit, and a chamber surrounding the inner conduit. The inner conduit communicates with the target fluid inlet and the target fluid outlet, and provides a flow path for a target fluid to be cooled. The chamber contains a first endothermic reactant and includes a reactant inlet selectively alterable from a closed state to an open state. When the reactant inlet is in the closed state, the first endothermic reactant is isolated from a second endothermic reactant and no endothermic reaction occurs. When the reactant inlet is in the open state, the reactant inlet provides a flow path for enabling the second endothermic reactant to come into contact with the first endothermic reactant in the chamber for initiating the endothermic reaction and cooling the target fluid in the inner conduit.
