Abstract (en)
The heater comprises a stack of elongated fretted radiators (10, 12, 14, 16, 18, 20) in thermal and electrical contact with PTC pellets (36) clamped between adjacent radiators, and at least one stiff elastic slat (40, 42) interposed between a respective pair of adjacent radiators, the facing surfaces of the latter having complementary ridges (24) and recesses (26, 28) whereby the slat is elastically deformed. The stack of radiators, with the PTC pellets and the slats, are sandwiched between two longitudinal beams (43) biased against the outermost radiators (10, 20) by two brackets (44, 46) that are attached to the opposite ends of the stack of radiators, in order to maintain the unit assembled.
