Heating metal element with an airflow passing through it

摘要

The shunt (1) has a zone (5) on which a resistive element (2) is fixed and another zone (6) exchanging heat with an air flow crossing the zone (6), where the zones form a matrix. The zone (5) extends in a plane and the zone (6) extends between the two planes that are separated from an angle between 0 and 80 degrees. The zone (6) is extended longitudinally from one end to another end, where the former end permits electrical contact of the shunt with an electric supply source. An independent claim is also included for a method for fabricating a heat bar.
