Smith, R J

This patent describes a heat transfer and conditioning unit connectively joining a fire chamber and an exhaust flue having an independent chamber for circulation of ambient air capable of transferring heat thereto comprising: a casing having exhaust inlets and exhaust outlets adapted for communication with a flue to the atmosphere; the casing containing adjacent walls, the opposing surfaces of the walls defining elongated passages arranged in longitudinal alignment for conducting exhaust gas containing products of combustion between the exhaust inlets and outlets; the walls being formed of a material suitable for the conductance of heat; each elongated passage having a passage inlet adjacent to the exhaust inlet and a passage outlet adjacent to the exhaust outlet, walls disposed parallel to each other and venturi. The venturi are located at each passage inlet and outlet and are periodically disposed along the elongated passage, each venturi is separated from adjacent venturi by portions of the wall disposed parallel to each other, the venturi and parallel portions of the wall defining compartments; the compartments containing a series of longitudinally and laterally extending fins; and the casing having an air inlet and an air outlet and a continuous chamber for the passage of ambient air between the inlet and the air outlet.
