Abstract

An assembly according to an exemplary aspect of the present disclosure includes, among other things, a top plate piece, a bottom plate piece and tubing sandwiched between the top plate piece and the bottom plate piece.

First claim

What is claimed is:

1 . An assembly, comprising:
a top plate piece; a bottom plate piece; and tubing sandwiched between said top plate piece and said bottom plate piece.

2 . The assembly as recited in claim 1 , wherein portions of both said top plate piece and said bottom plate piece overlap said tubing.

3 . The assembly as recited in claim 1 , wherein each of said top plate piece and said bottom plate piece include flared portions that overlap said tubing.

4 . The assembly as recited in claim 1 , wherein said tubing extends along a linear axis away from an edge of said assembly.

5 . The assembly as recited in claim 4 , wherein said linear axis extends between said top plate piece and said bottom plate piece.

6 . The assembly as recited in claim 1 , wherein said top plate piece and said bottom plate piece cooperate to establish a body of a cold plate assembly.

7 . The assembly as recited in claim 6 , comprising an extension that extends from said body, said tubing received by said extension.

8 . The assembly as recited in claim 7 , wherein said extension includes a platform connected to said body by a bridge, said platform elevated relative to said body.

9 . The assembly as recited in claim 1 , wherein said top plate piece includes a first flared portion and said bottom plate piece includes a second flared portion, said tubing received within an opening between said first flared portion and said second flared portion.

10 . The assembly as recited in claim 1 , comprising a passage formed between said top plate piece and said bottom plate piece.

11 . The assembly as recited in claim 10 , wherein said passage is a serpentine passage.

12 . The assembly as recited in claim 10 , wherein a portion of said tubing that is received between said top plate piece and said bottom plate piece extends along a linear axis that is parallel with at least a portion of said passage.

13 . The assembly as recited in claim 1 , wherein said tubing includes an inlet tube and an outlet tube.

14 . A battery assembly, comprising:
a plurality of battery cells; an enclosure assembly that houses said plurality of battery cells; and a cold plate assembly in contact with said plurality of battery cells, wherein tubing of said cold plate assembly protrudes through a wall of said enclosure, said tubing extending along a linear axis away from an edge of a body of said cold plate assembly.

15 . The assembly as recited in claim 14 , wherein said linear axis excludes any bends.

16 . The assembly as recited in claim 14 , wherein said body includes an extension and said tubing extends from said extension.

17 . The assembly as recited in claim 14 , wherein said body includes a flared portion and said tubing is received within an opening established by said flared portion.

18 . The assembly as recited in claim 14 , wherein said body is established by a top plate piece and a bottom plate piece, said tubing sandwiched between said top plate piece and said bottom plate piece.

19 . The assembly as recited in claim 14 , wherein said cold plate assembly is part of a thermal management system that includes a fluid source, an inlet and an outlet.

20 . The assembly as recited in claim 19 , wherein said tubing includes an inlet tube connected to said inlet and an outlet tube connected to said outlet.
