- the liquid-heating device for a motor vehicle comprises two parts 1a, 1b of substantially identical thermally conductive material, each of the parts having a path 10a, 10b of liquid flow formed integrally in the room to allow a flow of liquid between an inlet 11a, 11b and an outlet 12a, 12b.
- Different materials can be used for the manufacture of two parts, such as aluminum, or a ceramic with high thermal conductivity. For reasons which will be apparent in the following description, a material which has both a high thermal conductivity and an electrical conductivity will preferably be used.
- the device further comprises heating means 14 placed in thermal contact with each of the two parts la, Ib, used to indirectly heat the liquid passing inside the two flow paths 10a, 10b.
- each flow path 10a, 10b preferably follows a labyrinth-like shape, for example in the form of a spiral.

- the heater itself has two independent inputs and two independent outputs.
- the various inputs and outputs are advantageously provided on the same side of the two parts Ia and Ib.
- each of said first and second parts 1a, 1b comprises a flat bottom wall 15a, 15b extending in a plane parallel to the flow path 10a, 10b which it encloses. and a plurality of stones 14 with a positive temperature coefficient are arranged in a matrix in the same plane, parallel and in thermal contact with each of the bottom walls.
- the matrix which, in the schematic example comprises six stones 14, is thus sandwiched between the two bottom walls 15a, 15b to allow indirect heating of the liquid in the two flow paths 10a, 10b.
- the heating temperature obtained by electrically feeding this type of thermistors is self-limited. More specifically, these thermistors rise in temperature to obtain a substantially constant temperature value, corresponding to the so-called self-regulation temperature. It is therefore not necessary to provide a particular control device for the regulation of these elements.
- a first electrode is placed facing and in electrical contact with all the first faces of the stones to receive a first DC voltage value, typically the voltage delivered by the vehicle battery, and a second electrode is placed opposite and in electrical contact with all the second faces of the stones, to receive the neutral voltage value.

- the bottom walls 15a, 15b of the parts 1a and 1b are held in pressure against the faces of the stones, using either screws for holding parts la, Ib, or a layer of glue covering the faces of the stones on each side.
- screws it is advantageous to interpose, between the faces of the stones and the bottom walls 15a, 15b, a layer of electrically and thermally conductive grease, so as to compensate for differences in the geometry of the stones 14 and flatness imperfections for the bottom walls 15a, 15b, and thus ensure good thermal and electrical contact.
- glue it must have good heat conduction properties and a low or no electrical resistance.

This ensures that the faces will be well fed, even if some of the stones break down.
- Each of the two previous variants relating to the formation of the feed electrodes also has its own advantages.
- the choice of the material for producing parts 1a and 1b depends on its thermal conductivity capabilities alone.
- the material that composes them must necessarily be a good electrical conductor in addition to being a good thermal conductor. Nevertheless, this variant is of interest because it makes it possible to considerably simplify the electrical connection interface of the device as will now be explained with reference to FIGS. 3 and 4:
- the various elements described with reference to FIGS. 1, 2a and 2b are disposed inside a structure 2 made of electrically insulating material, for example plastic material, whose role is to simultaneously maintain the these elements and the electrical interface between the external power supply, typically the vehicle battery, and the parts la, Ib forming feed electrodes for the stones 14 with a positive temperature coefficient.

More precisely, the grid extends perpendicular to the planes containing the peripheral wall 20, and each mesh of the grid has the dimension adapted to accommodate one of the flat stones 14. It is thus guaranteed to always maintain an optimum distribution of the stones with respect to the surface of the bottom walls of the parts la, Ib.
- the walls of the grid 20 advantageously serve to avoid the migration of this glue which could be responsible for short circuits.
- the thickness of the walls must also be adjusted so that the faces of the flat stones 14 are at least flush on both sides of the grid.
- the structure further comprises a connector 22, preferably molded.
- Two electrical connection tabs 23a, 23b preferably metal plates overmolded in the structure, extend parallel across the connector.
- the free ends of these tabs 23a, 23b accessible from outside the structure 2 by the connector and not visible in the figures, form the male parts of the connector intended to be respectively connected to the battery and to a mass of the vehicle.
- the other two ends on the inside of the structure are connected respectively to parts 1a and 1b serving as electrodes.
- the wall of the frame opposite to that carrying the connector 22 advantageously comprises four cutouts 24, two to upper level, and two at the lower level, adapted to receive the ends of connections 11a, 11b, 12a and 12b parts and Ib when they are placed in the structure respectively from above and from below.
- the piece 1a is held in place inside the housing on the upper faces of the flat stones 14, in particular by means of a screw-type fastener 25 - nut 26 through an opening 160a whose connection terminal 16a of the piece is provided.
- the fixing screw 25 - nut 26 is metal, and when the piece is in place in the position shown in Figure 4, the tab 23a is in contact with the nut 26, and the piece is found in electrical contact with the screw
- the piece is thus able to serve as a feeding electrode for all the upper faces of the flat stones by receiving the voltage to which will be connected the lug or blade 23a via the metal fastener screw 25 - nut 26.
- a similar screw-nut attachment is provided for the piece Ib through an opening in its connection terminal 16b (see Figure 2b), but in this case, the corresponding nut is in contact with the other leg or blade 23b.
- the previous metal nut 26 could be replaced by any means of clamping the metal screw 25 for holding and electrically contacting the screw 25 with the blade 23.
- Two covers not shown in plastic are placed on the peripheral edge of the frame for closing the housing above the room 1a and below the part Ib. These two covers, associated with the structure 2 by gluing or by means of any means of sealing, guarantee the general sealing of the device.
- the heating device comprises two pieces 1a, 1b
- the invention can also be generalized to a heating device having only one piece of thermally conductive material, whether or not electrode for feeding the flat stones according to the two variants explained above with reference to FIGS. 3, 4, 5a and 5b.
- the bottom wall of this part is one of the electrodes of the flat stones, the other electrode being for example made of a deformable metal sheet positioned against the matrix, or that the two electrodes are each consisting of a deformable metal sheet, one being sandwiched between the bottom wall of the workpiece and one of the faces of the die, the other being disposed against the other face of the die.
