HEATING CONDUCTIVE WIRE-LIKE ELEMENT FOR THE MANUFACTURE OF A WASHER FLUID HEATING AND CARRYING PIPE WITH CONTROLLED LINEAR HEATING POWER, AND ASSOCIATED HEATING PIPE AND WIPER DEVICE

摘要

A heating conductive wire-like element is disclosed, having a heating conductive strand arranged in a helix around a central fibre, of which the pitch between strands in at least a first zone of the wire-like element is of a first value for producing a first linear heating power, and of which the pitch between strands in at least one second zone of the wire-like element is of a second value smaller than the first value in order to produce a second linear heating power higher than the first linear heating power. A washer fluid heating and carrying pipe including at least one fluid circulation canal situated near a heating conductive wire made from the aforementioned wire-like element is also disclosed. A wiper device for a glazed surface of a vehicle incorporating at least one such pipe, and a method of manufacturing a pipe is also disclosed.
