Abstract

Disclosed herein is a heat exchanger, comprising at least one electric resistance heating element, at least two conductors which are connected to the at least one electric resistance heating element in an electrically conductive manner in order to conduct electric current through the at least one electric resistance heating element and thereby heat the electric resistance heating element, at least one thermally conductive element for transferring heat from the at least one electric resistance heating element to a fluid to be heated, at least one electrically insulating element, which electrically insulates the at least two conductors, and at least one pipe, wherein the at least two conductors and the at least one electric resistance heating element are arranged within a cavity bounded by the pipe and the pipe lies on the at least one electrically insulating element under a compressive force at at least one contact surface.
