Heating element for a heating appliance, method of manufacturing the heating element and radiation heating appliance comprising such a heating element

摘要

#CMT# #/CMT# The heating body (1) useful in an apparatus for electrically heating the premises, comprises an electrical resistance (3) constituted of a metallic sheath and incorporating metallic fibers that are coiled and drowned in a dielectric insulator. The electric resistance is fixed by exclusively welding the metallic sheath on a surface of a diffuser (2) such as a plane metallic plate, and is formed of rectilinear sections connected to a curved section. The diffuser and the sheath are welded with one another by mutual fusion of metals thus constituting a welding zone. #CMT# : #/CMT# The heating body (1) useful in an apparatus for electrically heating the premises, comprises an electrical resistance (3) constituted of a metallic sheath and incorporating metallic fibers that are coiled and drowned in a dielectric insulator. The electric resistance is fixed by exclusively welding the metallic sheath on a surface of a diffuser (2) such as a plane metallic plate, and is formed of rectilinear sections connected to a curved section. The diffuser and the sheath are welded with one another by mutual fusion of metals thus constituting a welding zone. The surface of the diffuser has extrusions before welding. The metallic plate presents waves perpendicular to the rectilinear section of the electric resistance. The waves are situated between the welding zones. The diffuser is equipped with an external housing that partially includes the electric resistance. Independent claims are included for: (1) a process for producing the heating body; and (2) an apparatus for electrically heating the premises. #CMT#USE : #/CMT# The heating body is useful in an apparatus for electrically heating the premises (claimed), and in convectors, radiant panels, radiators and towel warmers. #CMT#ADVANTAGE : #/CMT# The heating body has simplified structure with improved reliability and thermal properties, can be easily and economically manufactured, and ensures constant and safe transfer of heat from the metallic fiber to the diffuser without any danger. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a vertical cross-sectional view of a heating body. 1 : Heating body 2 : Diffuser 3 : Electric resistance 8 : Covering 10 : Internal wall. #CMT#INORGANIC CHEMISTRY : #/CMT# Preferred Components: The diffuser and the sheath are made of steel.
