Abstract

The invention relates to a vehicle heater, comprising at least one pipe, which has a plurality of chambers, ceramic heating elements, which are arranged in the chambers, and contact plates, which rest against the heating elements in the chambers via a front side and face an upper side or underside of the chamber via a rear side, wherein at least two chambers of the pipe are separated by an intermediate wall, which runs from the upper side to the underside of these two chambers. The contact plates have a slit, in which the intermediate wall is arranged.

First claim

What is claimed is:

1. A vehicle heater, comprising:
a pipe having a plurality of chambers;
each chamber having a ceramic heating element arranged therein;
a contact plate configured for electrical contact, the contact plate having a front side contacting the heating elements and a rear side facing an upper side of the chambers or an underside of the chambers; and
an intermediate wall separating at least two of the chambers, the intermediate wall extending from the upper side to the underside of the chambers, wherein the contact plate has a slit in which the intermediate wall is arranged.

2. The vehicle heater according to claim 1 , wherein the contact plate has an extension at one end thereof that is inserted into a printed circuit board.

3. The vehicle heater according to claim 1 , wherein the contact plate comprises two contact plates that are arranged in each chamber and the heating elements are arranged between the contact plates.

4. The vehicle heater according to claim 1 , wherein the pipe comprises a plurality of pipes arranged side by side.

5. The vehicle heater according to claim 4 , wherein an end of the pipes is inserted into a mount.

6. The vehicle heater according to claim 4 , wherein the underside and the upper side of adjacent pipes face one another.

7. The vehicle heater according to claim 4 , wherein an end of the pipes is inserted into a base of a circuit housing in which a control circuit is arranged.

8. The vehicle heater according to claim 7 , wherein the control circuit is arranged on a printed circuit board.

9. The vehicle heater according to claim 1 , wherein the pipe is flat.

10. The vehicle heater according to claim 1 , wherein the intermediate wall is solid.

11. A vehicle heater, comprising:
a pipe having two chambers and an intermediate wall separating the two chambers;
each chamber having at least one ceramic heating element arranged therein; and
a contact plate configured for electrical contact, the contact plate having a slit in which the intermediate wall is arranged, the slit having an open end and a closed end;
wherein a front side of the contact plate contacts the heating elements in each of the two chambers and a rear side of the contact plate faces an upper side or underside of each of the two chambers.

12. The vehicle heater according to claim 11 , wherein the contact plate comprises two contact plates and the heating elements are arranged between the two contact plates.

13. The vehicle heater according to claim 11 , wherein the pipe comprises a plurality of pipes arranged side by side.

14. The vehicle heater according to claim 13 , wherein an end of the pipes is inserted into a mount.

15. The vehicle heater according to claim 13 , wherein the underside and the upper side of adjacent pipes face one another.

16. The vehicle heater according to claim 13 , wherein an end of the pipes is inserted into a base of a circuit housing, in which a control circuit is arranged.

17. The vehicle heater according to claim 11 , wherein the pipe is flat.

18. The vehicle heater according to claim 11 , wherein the intermediate wall is solid.

19. The vehicle heater according to claim 11 , wherein the two chambers comprise more than two chambers and the intermediate wall comprises a plurality of intermediate walls, each one of the intermediate walls separating two adjacent chambers.

20. The vehicle heater according to claim 19 , wherein the slit comprises a plurality of slits, each one of said slits having a respective one of said intermediate walls arranged therein.
