It is more particularly in the second part 15 of the pipe 10 that it is intended to be implanted although it is also possible to implant it in the first part 18 of said pipe 10, in combination or not with said second party.
- the first part 18 of the pipe for transporting and heating the liquid comprises two pipes 19 and 20 within which the liquid is able to circulate, each pipe corresponding to the supply
- liquid transport and heating devices are, for example, each made in the form of a
- each inner conduit corresponding to the windshield washer fluid supply for a particular direction of movement of the brush.
- the material constituting such a tube may be, for example, an elastomer or a rubber.
- This device for transporting and heating the liquid 10 further comprises a heating element (not visible in FIG. 1) which runs along the pipes and tubes, being embedded in the material constituting them.
- a heating element is a resistive element, which takes, in the prior art, the shape of a first and a second electrically conductive wires, which, when they are driven by an electric current, give off calories. It is therefore understood that this heating element forms a source of heat from which the device for transporting and heating the liquid draws energy and dissipates it all around the space in which the liquid is located or circulates.
- FIG. 2 shows the detail of the prior art implantation of a heater inside the liquid transport and heating device.
- Each tube 15 comprises a median wall 21 which separates the first duct 22 from the second duct 23.
- the heating element comprises the first electrically conductive wire which runs parallel to the second electrically conductive wire. These two son are connected to each other at their distal end, that is to say at the level of the blade, so as to form, in the prior art shown here, a cable to go back and forth in loop for the electric heating current.

- the entire heating element The entire heating element.
- This cable consists of two conductive wires 31 and 32, constituted by a series of braided strands, which extend parallel to one another and between which a predefined voltage difference is applied, the two conductors not being
- the resistivity of the die is scalable along the cable with its temperature, allowing a portion of the cable that is placed over its length in a colder environment to transmit more energy into that area. There is therefore a self-adaptation of the temperature of the cable for all its parts regardless of the thermal environment in which they are located.
- the invention proposes to use such a cable to ensure the heating of the liquid sent into the wiper blades, by miniaturizing it and by conforming it so that it accepts the stresses, both in tension and in flexion, which are generated by the back and forth of the transport device on the windshield.
- FIG. 4 shows, according to a first embodiment of the invention, a heating cable 30 embedded in the wall 21 of the washer fluid transport and heating device.
- the self-regulating heating cable 30 consists of the two heating wires 25 and 26 and a semiconducting matrix 33 which electrically connects them, the self-regulating cable being further protected by an insulating sheath.
- the heating cable 30 has, in section, an elongated shape, the large dimension of which is oriented in the direction of the wall 21.
- the heating generated by the self-regulating cable radiates throughout the height of the wall which is located between the first and second conduits 22 and 23 for circulating the liquid. It thus ensures a much better heating of the liquid than in the prior art of FIG. 2, where the heat was radiated from two points near the ends of said wall 21.
- the heating wires 25 and 26 of the self-regulating heating cable each have an end connected to a terminal of an electrical circuit intended to be connected to an electrical connector, not shown, so as to create a voltage difference between the wires.
- heating 25, 26 by an on-board electrical source, also not shown.
- Conventional conductive cables, also not shown, can connect the connector to the heating wires according to the relative positions of these elements on the vehicle.
- each wire is constituted by a cylindrical core made of an insulating fiber 27 on which are spirally wound metal strands 28. These strands, three in number, without this number being imperative, are contiguous to each other and they form a helix along the insulating fiber 27.
- the pitch of this helix is variable depending on the self-regulating performance desired for the temperature of the windshield washer fluid heating cable 30, as will be explained later with reference to FIG. FIG. 10. An increase in the pitch causes a lowering of the heating power at the same temperature.
- the helical structure gives considerable longitudinal flexibility to the self-regulating cable 30, whereas braided structures would have rigidity
- Figure 7 shows a second embodiment of a transport and heating device 15 according to the invention. This comprises, as in the previous case, a self-regulating cable 130 positioned in the middle wall 21
- This cable is constituted by two heating wires 125 and 126 which are positioned concentrically. They are both formed by metal strands which are helically mounted around a support fiber. The strands of the inner wire 125 are wound on an insulating central fiber 127, in a configuration similar to that of FIG.
- 25 strands of the outer wire 126 are helically wound on a cylinder constituted, for example, by a semiconductor matrix 133 similar to that 33 of the first embodiment, but in a cylindrical form.
- the assembly is enclosed in an electrically insulating sheath 134, before being embedded in the middle wall of the tube 15.
- FIG. 8 and 9 show a third embodiment.
- the two heating wires 225 and 226 are both made according to the structure illustrated in FIG. 5, that is to say that they are formed by metal strands wound, each helically on an insulating fiber 227. then embedded in a sheath 233 of semiconductor material. They are then rolled onto each other so form a twisted cable 230.
- FIG. 10 shows, in a diagram, for a given potential difference between the conducting wires, the heating power which is delivered by a heating cable 30, 130, 230 as a function of its temperature.
- the thick line curve shows the power dissipation in the prior art, with power remaining substantially constant due to the low resistivity of the conductive wires.
- the heating power emitted by the semiconductor matrix 33 does not increase during the heating phase. It is for example constant with certain alloys or decreases regularly during the heating phase.
- the power delivered is practically zero when the temperature of the cable reaches 70 °.
- the invention thus makes it possible to limit the temperature of the cable to 70 or 75 ° C. and thus neither to vaporize the windshield washer fluid nor to degrade the quality of the elastomer used to form the transport tubes for this liquid. This limitation of the temperature is carried out entirely autonomously, without it being necessary
- the heating son are preferably made in the form of metal strands 28 wound in helix around a fiber 27.
- the helical shape of the metal strands gives the desired freedom of deformation for the cable and allows, moreover, by a modulation of the pitch of the helix, to adjust the value of the limiting temperature that 'reaches this cable according to the heating power supplied. In any case, the temperature of the cable reaches a limit value when the heating power increases, by the self-regulating effect of the temperature of the cable.
- each tube 15 comprises, according to the prior art described above with reference to FIG. 2, a heating element formed by two heating wires 25, 26 embedded in the wall 21 of the tube 15 and connected at their distal end. The free end of each heating wire exits the tube, for example at the connecting device 14 of the
- the latter is included in an electrical circuit which forms a loop between a first terminal 40a and a second terminal 40b of an electrical connector 40 of the vehicle, connecting these terminals 20 to a source electricity to establish a potential difference between them.
- a self-regulating cable 30a having a length and determined electrical characteristics, is placed between the free end of the first heating wire and a conventional conductive cable 41a, minimizing the resistive losses, connected to the first terminal 40a of the electrical circuit.
- the self-regulating cable may be made according to one of the variants described above.
- This cable 30a therefore comprises a first conductive wire 31 and a second conductive wire 32 separated by a matrix enriched in carbon.
- the first lead 31 is connected to the free end of the heating wire 25, and at the other end of the self-regulating cable 30a, the second lead 32 is connected to the lead wire 41. at.
- connections of the wires 31, 32 of the self-regulating cable 30a with the heating wire 25 and with the conducting cable 41a can be effected efficiently and economic by crimped connectors 42a, 43a known to those skilled in the art. There is no need here to make these fittings removable.
- a similar arrangement is made with a second self-regulating cable 30b between the free end of the second heating wire 26 and the second terminal 40b of the electrical circuit.
- the connecting element 14 where the free ends of the heating son 25, 26 come out is usually under the hood, close to the windshield but sheltered from the wind.
- the self-regulating cables are therefore in a place where they are subjected to temperature conditions changing with the environmental conditions and being generally higher than those encountered in the duct 15.
- the self-regulating cables are therefore dimensioned such that their resistivity evolves to limit the current flowing through the wires 25, 26 of the heating element when the environmental conditions may cause the washing and washing device to overheat. in the tube 15.
- the self-regulating cable passes the nominal electric power to ensure the heating of the liquid, in particular to ensure thawing of the duct 15.
- the self-regulating cable (s) 30a, 30b may also have a portion embedded in the liquid transport duct, downstream of the heating element 25, 26, so
- the self-regulating cable (s) may be sized to cut off the power supply to the heating element when they are (are) subjected to a temperature. approaching 100 ° C, to prevent the appearance of water vapor in the pipes.
- the self-regulating cable (s) 30, 31, installed in series with a heating element according to the prior art here provide a thermostat function without introducing expensive electronics.
- the self-regulating cable 30a, 30b can completely replace the normal conductive cable between the terminal 40a, 40b of the connector 40 and the free end of the heating wire 25, 26 corresponding.
- This arrangement makes it possible in particular to use only a crimped connection 42a, 42b by self-regulating cable 30a, and thus to minimize congestion problems.
