Abstract

The invention relates to a thermal conditioning device for a fluid for a motor vehicle, said device comprising at least one thermal module ( 3 a, 3 b ) comprising:—a core ( 11 ) comprising a core body ( 12 ), and—an enclosure ( 13 a, 13 b ): able to be electrically powered so as to form a heat source and arranged around the core ( 11 ) so as to define a guide circuit ( 15 ) for the fluid to be thermally conditioned, the guide circuit ( 15 ) being defined between the body ( 12 ) of the core ( 11 ) and the enclosure ( 13 a, 13 b ). According to the invention, the enclosure ( 13 a, 13 b ) is arranged around the core ( 11 ) at a distance (e) from the body ( 12 ) of the core ( 11 ) comprised between 0.5 mm and 8 mm. The invention also relates to a heating and/or air conditioning apparatus comprising such a device.

First claim

1 . A device ( 1 ) for electrically thermally conditioning a fluid for a motor vehicle, said device ( 1 ) comprising at least one thermal module ( 3 a, 3 b ) comprising:
a core ( 11 ) comprising a core body ( 12 ), and a shell ( 13 a, 13 b ): adapted to be electrically powered so as to form a thermal source, and arranged around the core ( 11 ) so as to define a guide circuit ( 15 ) for guiding the fluid that is to be thermally conditioned, the guide circuit ( 15 ) being defined between the body ( 12 ) of the core ( 11 ) and the shell ( 13 a, 13 b ),
wherein the shell ( 13 a, 13 b ) is arranged around the core ( 11 ) at a distance (e) from the body ( 12 ) of the core ( 11 ) of between 0.5 mm and 8 mm.

2 . The device ( 1 ) as claimed in claim 1 , in which the shell ( 13 a , 13 b ) is arranged around the body ( 12 ) of the core ( 11 ) at a lateral distance (e) with respect to the body ( 12 ) of the core ( 11 ).

3 . The device ( 1 ) as claimed in one of claim 1 , in which a thermal module ( 3 a, 3 b ) extends along a longitudinal axis (A) and the distance (e) between the body ( 12 ) of the core ( 11 ) and the shell ( 13 a, 13 b ) of the thermal module ( 3 a, 3 b ) is substantially constant along the length of the shell ( 13 a, 13 b ).

4 . The device ( 1 ) as claimed in claim 1 , in which the body ( 12 ) of the core ( 11 ) and the shell ( 13 a, 13 b ) of a thermal module ( 3 a, 3 b ) are respectively of substantially cylindrical shape.

5 . The device ( 1 ) as claimed in claim 1 , in which the shell ( 13 a, 13 b ) comprises at least one electric heating resistance.

6 . The device ( 1 ) as claimed in claim 1 , in which the external surface of the body ( 12 ) of the core ( 11 ) is substantially smooth.

7 . The device ( 1 ) as claimed in claim 1 , in which the core ( 11 ) of a thermal module ( 3 a, 3 b ) has a fluid inlet end ( 23 a, 23 b ) and a fluid outlet end ( 24 a, 24 b ) opposite the inlet end ( 23 a, 23 b ).

8 . The device ( 1 ) as claimed in claim 7 , in which the core ( 11 ) comprises a predefined number of spacers ( 35 ) positioned between the body of the core ( 12 ) and the fluid inlet end ( 23 a, 23 b ) or fluid outlet end ( 24 a, 24 b ) of the core ( 11 ).

9 . The device ( 1 ) as claimed in claim 1 , arranged in a heating circuit for heating the interior of the vehicle.

10 . A heating and/or air-conditioning unit for a motor vehicle, comprising at least one thermal conditioning device ( 1 ) as claimed in claim 1 .

11 . The device ( 1 ) as claimed in one of claim 2 , in which a thermal module ( 3 a , 3 b ) extends along a longitudinal axis (A) and the distance (e) between the body ( 12 ) of the core ( 11 ) and the shell ( 13 a, 13 b ) of the thermal module ( 3 a, 3 b ) is substantially constant along the length of the shell ( 13 a, 13 b ).

12 . The device ( 1 ) as claimed in claim 11 , in which the body ( 12 ) of the core ( 11 ) and the shell ( 13 a, 13 b ) of a thermal module ( 3 a, 3 b ) are respectively of substantially cylindrical shape.

13 . The device ( 1 ) as claimed in claim 3 , in which the body ( 12 ) of the core ( 11 ) and the shell ( 13 a, 13 b ) of a thermal module ( 3 a, 3 b ) are respectively of substantially cylindrical shape.
