HELICOIDAL HEAT EXCHANGER WITH FINS AND BOILER EQUIPPED WITH SUCH EXCHANGER

摘要

The heat exchanger (6a) has a tube rolled in helix. Fins (14a) are equipped on a length of the tube. The fins are distributed in a continuous or discontinuous manner along the heat exchanger. Coils (15) of the heat exchanger are separated into three sets (A-C). Each coil set is made up of one or several coils or a portion of contiguous coils. An independent claim is also included for a boiler.
