Abstract

The heat exchanger has a tank with inlet and outlet connections. The secondary coil is wound spirally in the tank and consists of an outer tube with three minor tubes fitting inside the main tube. The tubes are welded to the end flanges and connect with the mating flanges and the main pipes. The ends of the outer tube are opened to atmospheric pressure so that the fluids in the two parts of the exchanger cannot mix in the event of leakage.
