摘要： The invention relates to a heat exchanger (1), comprising at least one electric resistance heating element (2), in particular at least one PTC element (3), at least two conductors (4), in particular circuit boards (6, 7), which are connected to the at least one electric resistance heating element (2) in an electrically conductive manner in order to conduct electric current through the at least one electric resistance heating element (2) and thereby heat the electric resistance heating element (2), at least one thermally conductive element (11) for transferring heat from the at least one electric resistance heating element (2) to a fluid to be heated, at least one electrically insulating element (22), which electrically insulates the at least two conductors (4), preferably from the at least one thermally conductive element (11), and at least one pipe (18), wherein the at least two conductors (4) and the at least one electric resistance heating element (2) are arranged within a cavity (19) bounded by the pipe (18) and the pipe (18) lies on the at least one electrically insulating element (22) under a compressive force at at least one contact surface (14). The aim of the invention is to operate the heat exchanger with high electric current under high voltage, for example greater than 50 V, without any risk to the surroundings, in particular persons. Said aim is achieved in that the pipe (18) has a greater thickness at the at least one contact surface (14) than outside of the at least one contact surface (14) and a step (17) is formed on the pipe (18) between the contact surface (14) and the region outside of the contact surface (14) as a result of the differing thickness.
