Abstract
Official abstract text for this publication.
A wall ring for a fan, with a fan wheel, includes at least one heating element for heating the wall ring. The heating element includes an electrically conductive heating layer which is disposed on the inner side of the wall ring facing the fan wheel. The electrically conductive heating layer of the heating element may be configured as an electrically conductive CNT coating having carbon nano-materials.
First claim
Opening claim text (preview).
The invention claimed is: 1. A wall ring for a fan having a fan wheel, comprising at least one heating element for heating the wall ring; wherein the heating element comprises an electrically conductive heating layer that is disposed on an inner side of the wall ring that faces the fan wheel; wherein the electrically conductive heating layer of the heating element is configured as an electrically conductive CNT lacquer having carbon nano-materials; and wherein the heating element has contact elements on side edges that run in the axial direction, so that the direction of a current flowing through the heating element faces in the circumferential direction of the wall ring. 2. The wall ring according to claim 1 , wherein the heating element covers a partial region of the inner side of the wall ring that runs in the circumferential direction. 3. The wall ring according to claim 1 , wherein the heating element covers a partial region of the inner side of the wall ring that runs in the axial direction. 4. The wall ring according to claim 1 , wherein multiple heating elements are disposed distributed on the inner side of the wall ring, facing the fan wheel, and their contact elements are connected in parallel or in series. 5. The wall ring according to claim 1 , wherein the heating element is designed for a low voltage between 3 V and 60 V. 6. A fan comprising the fan wheel and the wall ring according to claim 1 , wherein the wall ring encloses the fan wheel of the fan. 7. A wall ring for a fan having a fan wheel, comprising at least one heating element for heating the wall ring; wherein the heating element comprises an electrically conductive heating layer that is disposed on an inner side of the wall ring that faces the fan wheel; wherein the electrically conductive heating layer of the heating element is configured as an electrically conductive CNT lacquer having carbon nano-materials; and wherein the heating element covers the entire circumference of the inner side of the wall ring, in the circumferential direction, with the exception of an insulation gap that runs axially.
