HEAT EXCHANGER
First Claim
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.

Abstract
A heat exchanger having at least one electrical resistance heating element, two conductors connected electrically to the electrical resistance heating element to conduct electric current through the electrical resistance heating element and thereby to heat the electrical resistance heating element, a heat-conducting element for transferring heat from the electrical resistance heating element to a fluid to be heated, an electrical insulating element insulating electrically the two conductors and the at least one electrical resistance heating element, and at least one tube. The two conductors, the electrical insulating element, and the electrical resistance heating element are arranged within a cavity bounded by the tube. The heat exchanger has an adapter plate and a tube opening, each being arranged at an opening of the adapter plate, and the at least one tube being connected fluid-tight to the adapter plate, which is connected fluid-tight to an electronics housing and/or an HVAC system housing.
