<p>The invention relates to a device for heating a window washer liquid, comprising an enclosure (12) bounded by a generally tubular wall (14) and capable of being traversed by a hot fluid, as well as a serpentine coil (12) consisting of a tube wound into a multiplicity of turns (34), housed inside the enclosure and capable of being traversed by the window washer liquid, the serpentine coil (32) being extended by a liquid inlet pipe (36) and a liquid outlet pipe (38) for the window washer liquid, passing in a sealed manner through the wall of the enclosure. In accordance with the invention, the wall (34) comprises at least one pushed-in part (44) capable of coming into contact with the wound tube (32) to hold the latter at a distance from the wall and thus promote heat exchanges between the hot fluid and the window washer liquid. Application particularly to motor vehicles. <IMAGE></p> |
