The systems are positioned at the end faces of the branch pipes. The hoses are mounted inside the branch pipes for permitting reciprocation. One of the ends of the hoses is rigidly connected to the base of the branch pipes. The other end is wound on the driving drums to define outer and internal spaces. The system for supplying and discharging the heat carrier is in communication with the internal space. The branch pipes are oppositely coupled with the housing.
