Heating-element support frame for an electric radiator of a ventilation, heating and/or air-conditioning installation

摘要

The frame is shaped in the form of a hollowed-out box whose large faces (2,2'), intended to be traversed by an airflow (A) conveyed by a ventilating, heating or air-conditioning unit, are held at a distance from each other in order to create a heating-element receiving space between them. The frame is made of a single part in which retainers (15) for holding heating elements (3) e.g. positive temperature coefficient (PTC) resistors inside the space are located in the area of the large faces. An independent claim is also included for an electric-heater assembling method.
