Claims

1. A frame for fixing one or more cells, the frame comprising:
a frame body including a cooling duct configured to contain a cooling medium, formed in the body; and
a plug-in piece configured to connect to an adjacent frame for fixing one or more cells, wherein the cooling duct extends at least partially inside the plug-in piece, wherein the plug-in piece projects at least partially out of a frame plane of the frame, such that the plug-in piece is configured to project into a complementary opening in a plug-in piece of the adjacent frame, and
wherein the frame further comprises a sealing portion disposed radially between the plug-in-piece and the complementary opening of the plug-in piece of the adjacent frame wherein the sealing portion is configured to seal radially.
2. The frame of claim 1, wherein the plug-in piece has a round or rectangular cross section.
3. The frame of claim 1, wherein the plug-in piece includes a male part and a female part,
wherein the male part is configured to be introduced into the female part of the adjacent frame, and
wherein the female part is configured to receive the male part of the adjacent frame.
4. The frame of claim 3, wherein the sealing portion is formed as a radially outward extension of the male part of the plug-in piece.
5. The frame of claim 1, wherein the seal includes an O-ring or insertion part.
6. The frame of claim 1, wherein the seal includes a plurality of partial seals, so as to be multi-lipped.
7. The frame of claim 1, configured withstand pressure up to 10 bar maximum.
8. The frame of claim 1, further comprising:
a flow plate arranged in the plug-in piece.
9. The frame of claim 1, further comprising:
a flow surface arranged in the plug-in piece.
10. The frame of claim 9, wherein a roughness of the flow surface is greater than a roughness of a remainder of the plug-in piece.
11. The frame of claim 9, wherein a thermal conductivity of the flow surface is greater than a thermal conductivity of a remainder of the plug-in piece.
12. The frame of claim 9, wherein the flow surface is attached towards a cell body.
13. The frame of claim 1, further comprising:
a heat transfer fin arranged in the plug-in piece.
14. The frame of claim 1, further comprising:
a clip element formed in the plug-in piece.
15. The frame of claim 1, wherein the plug-in piece includes a strut, attached internally, the plug-in piece being mechanically stabilized by the strut.
16. An arrangement, comprising:
a first and a second of the frame of claim 1, the frames respectively including a first and a second of the plug-in piece; and
a cell,
wherein the cell is arranged between the frames,
wherein a male part of the first plug-in piece projects into a female part the second frame, and
wherein the cooling duct is directed through the plug-in piece.
17. The arrangement of claim 16, further comprising:
a seal, arranged on the male and/or the female part, is in a main line of force or in a force shunt.
18. The arrangement of claim 16, further comprising:
a tube, in which the cooling duct is formed, directed through the plug-in pieces.
19. The arrangement of claim 18, further comprising:
a tolerance compensator,
wherein the tube is directed through one opening in at least one of the plug-in pieces, and
wherein the tolerance compensator is arranged between the tube and inner wall of at least one opening.
20. The arrangement of claim 16, further comprising:
an external housing, which is part of the cooling duct,
wherein the plug-in piece of a last frame is introduced into a drilled hole in the housing.
21. A battery system, comprising:
the arrangement of claim 16.
22. The frame of claim 1, wherein the sealing portion is formed as a radially inward extension of the complementary opening.
