1. A heat exchanger comprising:

  • at least one electrical resistance heating element;

    at least two conductors connectable electrically to the at least one electrical resistance heating element to conduct electric current through the at least one electrical resistance heating element and thereby heat the electrical resistance heating element;

    at least one heat-conducting element for transferring heat from the at least one electrical resistance heating element to a fluid to be heated;

    at least one electrical insulating element that insulates electrically the at least two conductors and the at least one electrical resistance heating element;

    at least one tube having a tube opening;

    at least one cavity bounded by the at least one tube, the at least two conductors, the at least one electrical insulating element, and the at least one electrical resistance heating element are arranged within the at least one cavity; and

    an adapter plate having at least one opening and one tube opening, each being arranged at the opening of the adapter plate,wherein the at least one tube is connected fluid-tight to the adapter plate, andwherein the adapter plate is connected fluid-tight to an electronics housing and/or an HVAC housing.
