The heat exchanger pipes internally carry a current of a primary medium, and externally are surrounded by a secondary medium. From a dividing head for the primary medium at one end (A), the pipes extend several times forwards and backwards to the opposite end (B) of the exchanger, and are connected to a collection head. The pipes are supported by distance pieces to form a group, these pieces comprising separate fillets for stack-form location of the pipes. At the exchanger ends, there are 180 deg. pipe bends arranged traversely in pairs, and each group of pipes comprises two loops. The loops are connected for flow purposes to a single pipe with releasable connection to the dividing head, and partly to a further single pipe for connection to the collection head. |
