300 WATT PORTABLE THERMOELECTRIC GENERATOR.

Abstract

Two mock-up combustion chambers with differentlength heat collector fins were fabricated and tested. These tests were conducted to determine heat flux and burner efficiency. A heat flux of approximately 40 watts per sq in at 1100F was achieved with a corresponding burner efficiency of 62.5%. A fuel vaporizer was fabricated and tested with the present design burner head. Thermoelectric couples were fabricated and tested. These couples are of the same composition as will be used in the generator but have a slightly larger L/A ratio. The second model fin array was fabricated and tested. This fin array consists of 45 fin strips of 0.005-in.-thick aluminum soldered onto a 0.015-in.-thick stainless steel cylinder. A prototype voltage regulator was constructed and electrical tests were conducted.
