According to the invention, a heat exchanger (1) comprises at least one set of pipes (3, 4), each set of pipes (3, 4) comprising at least two pipes (3, 4), wherein the pipes (3, 4) are mechanically connected by at least one connection structure (5). At least two pipes (3, 4) are made from different metals having a different thermal expansion coefficient; at least two of the pipes (3, 4) having a different thermal expansion coefficient are joined by a soldered joint (lib) or by a brazed joint. At the joint (lib) of the two pipes (3, 4), the pipe (4) made of the metal having a lower thermal expansion coefficient is inserted into the pipe (3) made of the metal having a higher thermal expansion coefficient. The invention also relates to a household appliance (2), in particular clothes treatment appliance, comprising at least one such heat exchanger (1), and a method for manufacturing such heat exchanger (1). |
