Electric radiator with heat-transfer fluid made up of moulded modular elements

摘要

The radiator has modular elements (1), and a vertical heating tube (20) closed at its ends and enclosing an electric resistor (4) e.g. immersion heater, for heating a coolant. Each modular element comprises a vertical tubular element (2) housed in an envelope (11). The tubular element is retained in the envelope by spacers constituted by a pair of fins of a diffuser. The modular elements are connected between each other by connection pieces (12) at the level of the tubular elements such that each tubular element constitutes a section of the heating tube.
