<p>1435831 Thermal storage heaters NISSAN MOTOR CO Ltd 6 June 1973 [7 June 1972 13 July 1972 (2) 4 Oct 1972] 27058/73 Heading F4U [Also in Division H2] A thermal storage heater, e.g. for heating air to be discharged into a car interior, comprises a thermal storage core of block form 14 having passages 16 therethrough for the passage of air from an air inlet 22 to an outlet 24, control of the air flow being achieved by valves 30, 40 immediately upstream and downstream respectively of the core, and a auction fan 46, downstream of the valve 40. The core has surrounding thermal insulation 20, and electrical heating elements 18 connectable to an electric power source through leads 52, 52<SP>1</SP>. A circuit is described which governs the speed of the fan in accordance with the core temperature, the circuit including a thermo-electromotive device for producing an electric power related to the heat energy of the core and a constant voltage device connected to the thermoelectromotive device to produce a constant voltage which is supplied to the fan.</p> |
