Abstract

HEATEXCHANGER 5 THE INVENTION RELATES TO A HEAT EXCHANGER WHICH FACILITATES THE TRANSFER OF HEAT FROM A HEAT TRANSFER FLUID FLOWING IN A TUBE TO A FLAT OR CURVED SURFACE AND VICE VERSA. ONE EMBODIMENT OF THE HEAT EXCHANGER (1) COMPRISES AN INTEGRAL PIECE OF METAL HAVING AT LEAST ONE TUBE (1 1) WITH THE OR EACH OF THE TUBES (II) INTEGRALLY CONNECTED LONGITUDINALLY TO THE TOP SURFACE (17) OF A BAR (12) AND WITH THE BOTTOM 10 SURFACE (18) OF THE BAR (12) IN GOOD THERMAL CONTACT WITH THE FLAT OR CURVED SURFACE WHERE HEAT IS TO BE TRANSFERRED ONTO FROM THE HEAT TRANSFER FLUID FLOWING THERE THROUGH THE OR EACH OF THE TUBES (I 1) OF THE HEAT EXCHANGER (1). IN ANOTHER EMBODIMENT, THE HEAT EXCHANGER (2) COMPRISES AN INTEGRAL PIECE OF METAL HAVING AT LEAST A PAIR OF WINGS (25), WITH THE OR EACH PAIR OF WINGS (25) 15 INTEGRALLY CONNECTED LONGITUDINALLY TO THE TOP SURFACE (27) OF A BAR (22) AND WITH THE WINGS (25) RISING FROM THE TOP SURFACE (27) OF THE BAR (22), FORMING A SUBSTANTIALLY U- SHAPED CHANNEL (23) BETWEEN EACH PAIR OF WINGS (25). IN THIS EMBODIMENT, A TUBE OR A TUBULAR ELECTRIC HEATING ELEMENT (10) MAY BE CIRCUMFERENTIALLY ENCLOSED IN A CHAMBER (24) FORMED BY PRESSING THE PAIR OF WINGS (25) TOWARDS ONE ANOTHER WHEN THE TUBE OR 20 THE TUBULAR ELECTRIC HEATING ELEMENT (10) IS PLACED IN THE SUBSTANTIALLY U-SHAPED CHANNEL(23). THE HEAT EXCHANGER OF THIS INVENTION CAN HAVE NUMEROUS POSSIBLE COMBINATIONS OF TUBES AND WINGS CONNECTED TO THE BARS TO TRANSFER HEAT TO OR FROM A FLAT OR CURVED SURFACE. 25
