Abstract
(EN)
Disclosed is a heater comprising a ceramic heater element and ceramic heat sink whereby the ceramic heater element and the ceramic heat sink are both formed from a plurality of layers of tape cast ceramic material. The ceramic heater element may be generally planar and extends within a first plane. The ceramic heat sink may extend in a second plane which is orthogonal to the first plane. The ceramic heat sink may comprise a plurality of fins which may be discrete. The layers of the ceramic heater element may be orientated orthogonal to the layers of the ceramic heat sink. The ceramic heater element may comprise a conductive track which may be surface mounted to a distal side of the ceramic heater element than the ceramic heat sink or embedded within the ceramic heater element.

L'invention concerne un dispositif de chauffage comprenant un élément chauffant en céramique et un dissipateur thermique en céramique, l'élément chauffant en céramique et le dissipateur thermique en céramique étant par là-même tous deux constitués d'une pluralité de couches de matériau céramique coulé en bande. L'élément chauffant en céramique peut être généralement plan et s'étend à l'intérieur d'un premier plan. Le dissipateur thermique en céramique peut s'étendre dans un second plan orthogonal au premier plan. Le dissipateur thermique en céramique peut comprendre une pluralité d'ailettes qui peuvent être séparées. Les couches de l'élément chauffant en céramique peuvent être orientées orthogonalement aux couches du dissipateur thermique en céramique. L'élément chauffant en céramique peut comprendre une piste conductrice qui peut être montée en surface sur un côté distal de l'élément chauffant en céramique par rapport au dissipateur thermique en céramique ou incorporée dans l'élément chauffant en céramique.
