FEASIBILITY INVESTIGATION OF THE VAPOR CHAMBER FIN.
Abstract
The feasibility of using the vapor chamber fin(heat pipe) technique for a Rankine space radiator was investigated and found to have significant merit. Further analysis, which compared configuration pumping type heat pipes to the more conventional wick-type, indicated that the wick types have decisive advantages. With the aid of computer programs and laboratory tests, a heat pipe has been developed utilizing only one wrap of wire mesh wick. This development resulted in an appreciable weight savings. A radiator system design employing this type of heat pipe, is presented herein. This design has a .99 probability of having 95% of its original heat rejection capability at the end of 10,000 hours. The weight to power ratio of the system is only .24 lb. /kilowatt. This is about one-third of the specific weight of previous systems and represents a substantial improvement in the state-of-the-art.
