Abstract
A RELIABLE, EFFICIENT MEANS FOR MOVING LARGE AMOUNTS OF HEAT FROM THE SOURCE TO A HEAT SINK WILL BE REQUIRED FOR THERMAL MANAGEMENT SYSTEMS IN FUTURE AEROSPACE APPLICATIONS, SUCH AS TRANSATMOSPHERIC VEHICLES. THE HEAT PIPE IS JUST SUCH A DEVICE, AND THROUGH PROPER SELECTION OF THE CASE MATERIAL AND WORKING FLUID, CAN OPERATE NEAR-ISOTHERMALLY FROM 5-2300K. HEAT PIPES HAVE BEEN PRODUCED SINCE THE 1960S. HOWEVER, ULTRAMET PROPOSES A UNIQUE AND INNOVATIVE METHOD OF PRODUCING HEAT PIPES, UTILIZING THE PROCESS OF CHEMICAL VAPOR DEPOSITION (CVD). THE HEAT PIPE WILL BE SEAMLESS, WITH THE EXCEPTION OF THE FILL PORT, THEREFORE GREATLY INCREASING ITS RELIABILITY. THE WICK MAY BE MACHINED INTO NUMEROUS GEOMETRIES, AND THE WALL WILL BE DEPOSITED SUCH THAT IT ASSUMES THE SHAPE OF THE WICK.
