Abstract
The present specification relates to heater element, device provided therewith and method for manufacturing such heater element. The heater element comprises a heater of a resistance heating metal that is provided in, at or close to a fluid path configured for heating fluid, wherein the heater comprises a conductor that is provided with a porous ceramic layer. In embodiments, the ceramic layer is provided on or at the conductor with plasma electrolytic oxidation. The ceramic layer has a thickness in the range of 5-300 μm.
Claims21
A heater element for heating a fluid, comprising:
- a heater of a resistance heating metal that is provided in, at or close to a fluid path configured for heating fluid,
- wherein the heater comprises a conductor that is provided with a porous ceramic layer.
(canceled)
An insulated conductor comprising a metal conductor that is provided with a ceramic layer as an electrically insulating layer.
A method for manufacturing a heater element and/or device, the method comprising the steps of:
- providing a conductor of a resistance heating metal;
- and
- performing plasma electrolytic oxidation in a plasma electrolytic oxidation chamber to deposit a porous ceramic layer on the conductor.
A method for heating a fluid, wherein:
- a heater of a resistance heating metal is provided in, at or close to a fluid path configured for heating fluid,
- wherein the heater comprises a conductor that is provided with a porous ceramic layer;
- wherein the porous ceramic layer is provided on or at the conductor with plasma electrolytic oxidation;
- wherein the heater comprises a spiralled metal wire as the conductor, wherein the wire is provided with the porous ceramic layer;
- and
- wherein the metal wire comprises titanium.
