Electrical heater for automobile, has lamellas with elongated holes exhibiting longitudinal edges that clamp heating rods, where portion of elongated holes in each lamella is longer than breadth of heating rods

摘要

The heater has multiple heating rods (1) that are connected with each other by multiple lamellas such that the lamellas are provided on the heating rods. The lamellas (4) have elongated holes (3) that extend in a longitudinal direction (10) of the lamellas. The elongated holes have longitudinal edges that are opposite to each other, where the longitudinal edges clamp the heating rods. A portion of the elongated holes in each lamella is longer than the breadth of the heating rods, which is measured in the longitudinal direction of the lamellas.
