Abstract:
The section bar (1) for a fluid flow heater for coffee machines has a longitudinal development with two opposing ends and a first tubular cavity (A), that is accessible at the opposing ends of the section bar (1), and a second cavity (B) having an opening (O) that extends along the longitudinal development of the section bar (1). A heater (10) having an encased resistor (2, 3) integrated in the first cavity (A) of the section bar (1) and a tubular fluid circulation conduit (4) inserted into the second cavity (B) of the section bar (1) and fixed by means of bending at least one lug (B1, B2, B3) around the tubular fluid circulation conduit (4), so that the opposing ends of the tubular fluid circulation conduit (4) emerge with respect to the opposing ends of the section bar (1).
Abstract:
An armored resistor (1) comprising a tubular casing (2) in which a metallic heating element (3) immersed in an electrically insulating material (4) is arranged. Furthermore, a first closing element (5) and a second closing element (6) of the tubular casing (2) are provided, in which the first closing element (5) is fluid-tightly fixed to the respective first end (7) of the tubular casing (2), and the second closing element (6) is provided with at least one at least one radial protrusion (15) which abuts on the second end (8) of the tubular casing (2), and which delimits at least one passage (16) communicating with the inside of the tubular casing (2), adapted to allow the passage of the electrically insulating material during the manufacturing of the armored resistor.
