Abstract
Official abstract text for this publication.
Disclosed is a heating device comprising a heating resistor, and a heat sink thermally coupled to the heating resistor, wherein the heat sink comprises corrugated fins that are skived fins integral to the heat sink. Also disclosed is a method for producing a heating rod.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing a heating rod, comprising: providing a tube with heat sink fins by skiving, wherein the skiving is done with a blade, whereby heat sink fins are formed by the skiving; providing the tube as a flat tube having broad sides and narrow sides, at least one of the broad sides having a surface that bulges inward, wherein the fins are positioned on at least one of the broad sides of the tube and ledges are positioned on opposite edges of the tube outside a width spanned by the fins; then inserting a ceramic heating resistor in the tube; and then compressing the tube by applying pressure to at least one of the ledges, whereby the flat tube is reduced in thickness and the at least one of the broad sides that bulges inward is flattened by the compressing, and whereby the pressure is applied to the at least one of the ledges after the fins are present on the tube. 2. The method for producing a heating rod according to claim 1 , wherein the applying pressure comprises applying pressure to both ledges of the tube. 3. The method for producing a heating rod according to claim 2 , wherein both broad sides are flattened by the compressing.
