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.
