Heat exchanger
First Claim
1. A heat exchanger comprising:
- at least one electrical resistance heating element;
at least two conductors electrically connected 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 two heat-conducting elements that transfer heat from the at least one electrical resistance heating element;
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 that corresponds to the tube opening of the at least one tube,wherein the at least one tube is connected fluid-tight to the adapter plate,wherein the adapter plate is connected fluid-tight to at least one of an electronics housing or an HVAC housing, andwherein the at least two heat conducting elements, are attached to opposing outer surfaces of the at least one tube, such that the at least one tube is positioned between the at least two heat conducting elements.

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.
