1. A heat exchanger comprising a plurality of exchange tubes (1) mounted joined longitudinally in such a way as to create a front surface portion (4) creating an obstacle to an incident heat flow and at least one heat flow sensor (5) disposed in a support (12) located between two adjacent exchange tubes (1), wherein:
the two adjacent tubes (1) each have, at their joined portion, a slight local deformation (11), in such a way as to allow the positioning of the heat flow sensor (5) support (12) by insertion between the two tubes; the heat flow sensor (5) is mounted movably in said support (12), the latter having the shape of a hollow enclosure made in such a way as to be able to be inserted between the two adjacent tubes (1), at the location of said local deformations (11);and characterized in that the support (12) of the heat flow sensor (5) is brazed to at least one of the two tubes (1) and is flattened on the side that is to be disposed at the front (4), with reference to the incident heat flow, in such a way as to be able to be inserted between the two adjacent tubes (1) at the location of said local deformations (11). |
