Abstract
A device for homogeneous heating of an object (O) comprises a supporting surface (2) for supporting the object (O), and a heating layer (3) arranged on the supporting surface (2). The heating layer (3) absorbs at least partly energy received from a source (4) and emits at least partly the thus-absorbed energy to the object (O) supported on the supporting surface (2). The layer (3) is made of such a material that the energy absorbed by the layer (3) is in a self-regulating manner distributed uniformly along the surface of the layer (3). The heating device forms a simple and compact unit which can be used to rapidly heat the object (O) to a homogeneous temperature.
Claims21
A device for homogeneous heating of an object (O), characterised by a supporting surface (2) for supporting the object (O) and a layer (3) which is arranged on the supporting surface (2) and which at least partly absorbs energy received from a source (4) and which at least partly emits the thus-absorbed energy to the object (O) supported on the supporting surface (2), the layer (3) being made of such a material that the energy absorbed by the layer (3) is in a self-regulating manner is distributed uniformly along the surface.
A device as claimed in any one of the preceding claims, wherein the layer (3) comprises a layer of carbon, preferably graphite.
A device as claimed in any one of the preceding claims, wherein the layer (3) is arranged essentially parallel with the supporting surface (2).
A device as claimed in any one of the preceding claims, wherein a thermally insulating element (7) is arranged at the side of the layer (3) facing away from the supporting surface (2).
A device as claimed in any one of the preceding claims, wherein an electrically insulating element (5) is arranged at the side of the layer (3) facing the supporting surface (2).
A device as claimed in any one of the preceding claims, wherein a rigid protective element (6) is arranged at the side of the layer (3) facing the supporting surface (2).
A device as claimed in any one of the preceding claims, wherein the protective element (6) allows a high degree of heat transport from the layer (3) to the supporting surface (2).
