11. A method for assembling a heat exchanger, said method comprising the following steps:
providing a pipe which has a pipe end portion that is positioned at an open end of the pipe;
placing a head part, which has an opening and a radial outside wall, on the pipe, such that the pipe fits through the opening of the head part;
placing a seal, which is an O-ring, on the pipe, such that the seal is received by the head part between the pipe and the radial outside wall;
widening the pipe end portion at least in part;
placing a tank component on the widened pipe end portion, such that the tank component is in contact with the head part, wherein the seal is placed between the head part and the tank component, and
crimping together the head part and the tank component, wherein the widened pipe end portion is surrounded by the tank component and/or by the head part,
wherein the tank component comprises an inner step or a flange which is capable of coming into abutment on the widened pipe end portion so that the pipe is prevented from being pushed into the tank component.
