Abstract (en)
The heater comprises a stack of elongate heating elements (10) containing PTC plates (32) in thermal and electric contact with elongate fretted radiators (12) alternating therewith. The heating elements and the radiators have a plurality of aligned transverse holes (28, 40) defining respective transverse passages, in which are received respective helical springs (20) that are hooked at their opposite ends to rods (18) extending parallelly along the two longitudinal sides of the stack. Two brackets (22, 24) close the opposite ends of the stack and have holes (58, 60) in which the opposite ends of said rods (18) are received and retained.
