SECTION BAR FOR A HEATER AND FLUID FLOW HEATER, IN PARTICULAR FOR COFFEE MACHINES
First Claim
1. A section bar for a fluid flow heater, in particular for coffee machines, having a longitudinal development of predefined length, greater than any dimension of a cross-section of the section bar, with two opposite ends, defining a first tubular longitudinal cavity, with openings in said opposite ends, and a second cavity having a lateral opening, which extends along the longitudinal development of the section bar, configured to house a tubular duct by means of insertion in a transversal direction with respect to said longitudinal development, said first and second cavities being placed side by side according to a first plane, (α
- ) said second cavity being U-shaped or J-shaped, said second cavity comprising a single lug oriented such as to define a direction of insertion for said tubular duct or a pair of lugs which are parallel to each other and define a direction of insertion for said tubular duct of fluid circulation, characterised in that said single lug or said pair of lugs have a smaller thickness with respect to a thickness of a perimeter wall defining said first cavity.

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).
