Abstract

A heating and cooling apparatus for a battery may include a base plate in which at least one fluid path for flowing-through of at least one of a coolant and a refrigerant is provided. At least one support part may be provided, in which in each case at least one electrical heating element is provided that is thermally coupled to the base plate. The heating and cooling apparatus may include a cover plate. The base plate, the at least one support part and the cover plate may be arranged adjacent to one another along a stack direction.

First claim

The invention claimed is:

1. A heating and cooling apparatus for a battery, comprising:
a base plate including at least one fluid path for flowing-through of at least one of a coolant and a refrigerant;
at least two support parts each including at least two first passage openings, the at least two first passage openings respectively having an electrical heating element arranged therein that is thermally coupled to the base plate;
an electrical insulation plate including at least two second passage openings;
a cover plate;
wherein the base plate, the at least two support parts, the electrical insulation plate and the cover plate are arranged in a stack along a stack direction, and the electrical insulation plate disposed between the base plate and cover plate in the stack direction; and
wherein the at least two second passage openings extend through the electrical insulation plate in the stack direction and are spaced from one another in the electrical insulation plate, and wherein each of the at least two support parts are arranged in a respective one of the at least two second passage openings of the electrical insulation plate.

2. The heating and cooling apparatus according to claim 1 , wherein the at least two support parts each define an elongated support frame extending along a longitudinal direction running orthogonally to the stack direction;
the at least two first passage openings extend through the elongated support frame of the at least two support parts in the stack direction and are spaced separate from one another along the longitudinal direction; and
the elongated support frame of the at least two support parts defines a transverse section separating the at least two first passage openings from one another, the transverse section extending along a transverse direction running orthogonally to the stack direction and the longitudinal direction.

3. The heating and cooling apparatus according to claim 2 , wherein at least one of:
the heating element has a respective top side that terminates flush with a top side of the support frame defined by each of the at least two support parts; and
the heating element has a respective bottom side that terminates flush with a bottom side of the support frame defined by each of the at least two support parts.

4. The heating and cooling apparatus according to claim 1 , the electrical insulation plate is composed of an electrically insulating material.

5. The heating and cooling apparatus according to claim 4 , further comprising an electrically conductive contact plate provided between the at least two support parts and the electrical insulation plate for electrically connecting to an external energy supply unit.

6. The heating and cooling apparatus according to claim 1 , wherein the at least two second passage openings provided in the electrical insulation plate are shaped complementary to the at least two support parts.

7. The heating and cooling apparatus according to claim 1 , wherein the at least two support parts are arranged sandwiched in the at least two second passage openings of the electrical insulation plate between the base plate and the cover plate.

8. The heating and cooling apparatus according to claim 1 , wherein the electrical insulation plate on a side facing the base plate has a surface geometry shaped complementary to the base plate.

9. The heating and cooling apparatus according to claim 1 , wherein the at least one fluid path provided in the base plate includes at least one flat tube, the at least one flat tube extending along a longitudinal direction of the base plate.

10. The heating and cooling apparatus according to claim 9 , wherein the at least one flat tube includes at least two flat tubes extending along the longitudinal direction of the base plate and spaced apart from one another on a side of the base plate facing the electrical insulation plate.

11. The heating and cooling apparatus according to claim 10 , wherein the at least two second passage openings of the electrical insulation plate and the at least two flat tubes of the base plate are arranged alternately next to one another with respect to a transverse direction common to the base plate and the electrical insulation plate, the transverse direction running orthogonally to the longitudinal direction and the stack direction.

12. The heating and cooling apparatus according to claim 9 , wherein the at least one flat tube is at least one of integrally moulded on the base plate, soldered onto the base plate, and welded onto the base plate.

13. The heating and cooling apparatus according to claim 1 , wherein the heating element arranged in each of the at least two first passage openings of the at least two support parts is a positive temperature coefficient (PTC) heating element.

14. The heating and cooling apparatus according to claim 1 , wherein the electrical insulation plate has a transversely extending recess disposed between the at least two second passage openings on a side facing towards the cover plate.

15. The heating and cooling apparatus according to claim 1 , wherein at least one of:
the heating element is fixed in a corresponding one of the at least two first passage openings of the at least two support parts via an adhesive; and
the at least two first passage openings provided in each of the at least two support parts have a rectangular shape.

16. A heating and cooling apparatus for a battery, comprising:
a base plate including at least one fluid path extending along a longitudinal direction of the base plate for flowing-through of at least one of a coolant and a refrigerant;
an elongated support frame extending along the longitudinal direction of the base plate, the support frame defining at least two separate passage openings;
at least two electrical heating elements disposed in the at least two separate passage openings of the support frame, respectively;
an electrical insulation plate defining a passage opening extending along the longitudinal direction of the base plate;
a cover plate;
the base plate, the support frame, the electrical insulation plate, and the cover plate arranged in a stack along a stack direction, the stack direction running orthogonally to the longitudinal direction, wherein the support frame and the electrical insulation plate are disposed between the base plate and the cover plate along the stack direction;
the support frame further defining a first surface and a second surface disposed opposite to the first surface with respect to the stack direction, wherein the at least two separate passage openings extend through the support frame from the first surface to the second surface, and the at least two electrical heating elements are respectively provided in the at least two separate passage openings thermally coupled to the base plate;
wherein the at least two separate passage openings are spaced from one another in the longitudinal direction and separated by a transverse section defined by the support frame, the transverse section extending along a transverse direction running orthogonally to the longitudinal direction and the stack direction; and
wherein the support frame is arranged in the passage opening of the electrical insulation plate.

17. A heating and cooling apparatus for a battery, comprising:
