Title: Tube-in-tube thermophotovoltaic generator

Abstract

A thermophotovoltaic device includes at least one thermal radiator tube, a cooling tube concentrically disposed within each thermal radiator tube and an array of thermophotovoltaic cells disposed on the exterior surface of the cooling tube. A shell having a first end and a second end surrounds the thermal radiator tube. Inner and outer tubesheets, each having an aperture corresponding to each cooling tube, are located at each end of the shell. The thermal radiator tube extends within the shell between the inner tubesheets. The cooling tube extends within the shell through the corresponding apertures of the two inner tubesheets to the corresponding apertures of the two outer tubesheets. A plurality of the thermal radiator tubes can be arranged in a staggered or an in-line configuration within the shell. 8 figs.

  • This patent describes the art of removing corrosive deposits from locations within a heat exchanger in which the heat exchanger is characterized by an enclosed tank containing heat exchanger tubes which are closely packed together and support plates arranged transverse to and sequentially spaced along the longitudinal axis of the heat exchanger tubes and forming junctions therewith, where the support plates contain a multiplicity of transverse holes extending through their entire thickness and where crevices exist between the outer surface of the heat exchanger tubes and the support plates at the site of the junctions and wherein these crevices andmore » the holes in the support plates act as flow holes to permit liquid which is placed in the enclosed tank to rise to a multiplicity of levels within the tank. The heat exchanger also contains an outer shell and a tube support sheet at the lower extremity of the tank to provide a base support for the multiplicity of heat exchanger tubes.« less
