2. The kit of claim 1 wherein at least one of the first and second forming members includes first and second passageways.

3. The kit of claim 2 wherein the first forming member includes an inlet into the first passageway and an outlet that opens into the second passageway and wherein the first and second passageways are completely separate.

4. The kit of claim 3 wherein the first forming member includes the first plug insert secured to the second end and a second plug insert secured to the first end for blocking at least one of the first and second passageways.

5. The kit of claim 3 wherein the second forming member includes first and second passageways, a bridge passageway adjacent the second end that links the first and second passageways and an inlet into the first passageway and an outlet into the second passageway where the inlet and outlet are both proximate the first end of the second forming member.

6. The kit of claim 5 wherein the inlet and outlet that open into the first and second passageways formed by the second forming member open in opposite directions.

7. The kit of claim 5 wherein the first forming member includes at least one connecting recess that opens into the first and second passageways formed by the first forming member wherein, when the first end of the second forming member is received in the connecting recess, the inlet and outlet of the second forming member open into the first and second passageways formed by the first forming member.

8. The kit of claim 7 wherein the first forming member includes a plurality of connecting recesses that open into the first and second passageways formed by the first forming member wherein each of the connecting recesses can receive a first end of a second forming member so that the inlet and outlet of the received second forming member opens into the first and second passageways formed by the first forming member.

9. The kit of claim 7 wherein the first forming member includes first and second oppositely facing surfaces and wherein the inlet and outlet are formed in the first surface and the connecting recess is formed in the second surface.

10. The kit of claim 2 wherein at least a subset of the first and second forming members form a single passageway and include both an inlet and an outlet that open into the single passageway.

11. The kit of claim 1 wherein the passageways are formed along lengths of the first and second forming members and wherein the first and second forming members include at least one of an inlet and an outlet that opens through a side wall portion of at least one of the first and second forming members into at least one of the passageways.

12. The kit of claim 1 wherein at least a subset of the first and second forming members include external surfaces that form O-ring receiving channels for receiving the at least one of the plurality of elastomeric seals when the first and second forming members are secured together.

13. The kit of claim 1 wherein at least a subset of the first and second forming members are substantially rectilinear in cross section.

14. The kit of claim 1 wherein at least one of the first and second forming members includes first and second passageways, a bridge passageway adjacent the second end that links the first and second passageways and an inlet into the first passageway and an outlet into the second passageway where the inlet and outlet are both proximate the first end of the at least one of the first and second forming members.

15. The kit of claim 1 for use in cooling at least one electrical component, the electrical component including a coil having a plurality of turns disposed over at least one of the passageway forming members.

16. The kit of claim 1 wherein each forming member comprises an extruded forming member.

17. A method of configuring a cooling assembly, the method comprising the steps of:

extruding a first manifold member that forms at least one manifold passageway that is defined at least in part by a first manifold wall member where the first manifold wall member forms a first external surface of the first manifold member;

extruding a second manifold member that forms at least one passageway that is defined at least in part by a second manifold wall member where the second manifold wall member forms a second external surface of the second manifold member;

forming a first port in the first external surface that opens into the passageway formed by the first manifold;

forming a second port in the second external surface that opens into the passageway formed by the second manifold;

providing an elastomeric seal between the first manifold member and the second manifold member; and

securing the second manifold member to the first manifold member, such that the first port, the elastomeric seal, and the second port are in substantial structural alignment and the elastomeric seal is sandwiched between and in substantial contact with both the second manifold member and the first manifold member to form a seal between the second manifold member and the first manifold member.

18. The method of claim 17 further including the step of forming a circular recess in the first external surface and wherein the step of providing an elastomeric seal includes placing an elastomeric O-ring in the circular recess.

19. The method of claim 18 wherein the passageway formed by the first manifold includes first and second ends and wherein the method further includes the step of securing a plug insert into at least the first end of the passageway to close the passageway formed by the first manifold.

20.

25. The method of claim 24 further including the step of, prior to forming the inlet and outlet ports, removing a portion of the tube adjacent the first end to form a cylindrical connection head portion through which the first and second passageways pass, the step of forming the inlet and outlet ports including forming the ports in the head portion.
