ABSTRACT:
A heat exchanger (1) with at least one heat-exchange tube (11) which is held at the end in an end piece (3) such that the joint is liquid- and gas-tight. The end piece (3) has an opening for each tube to which it is connected, allowing the heat-exchange fluid to pass through from the tube (11) into a conduit box and in the opposite direction, a sleeve-like connection socket (8) being located in the region of each opening. The connection socket (8) comprises a cylindrical slot (9) coaxial to the opening and open at the heat-exchange tube end, forming an inner (14) and outer (15) annular wall. The end of the heat-exchange tube (11) is pushed into the slot. A section of the outer annular wall (15) adjacent to the heat-exchange block is longer than the corresponding section of the inner annular wall (14).
