Abstract

Cooling systems include a first passageway forming member that includes first and second ends and at least one connecting recess that opens into first and second passageways formed by the first passageway forming member. A second passageway forming member includes first and second ends and inlet and outlet ports proximate the first end such that the first end, including an elastomeric seal and the inlet and outlet ports, is sealably insertable in and removable from the at least one connecting recess, where the inlet port opens into the first passageway and the outlet port opens into the second passageway, and where, when the first end is inserted in the at least one connecting recess, the elastomeric seal is sandwiched between and in substantial contact with both the first end and the first passageway forming member.

Claims

1. A modular cooling system comprising:

at least a first passageway forming member and a second passageway forming member, each of the first and second passageway forming members having first and second ends and forming at least one passageway and at least one of an input port and an output port that opens into the passageway;

the second passageway forming member including first and second passageways, a bridge passageway adjacent the second end of the second passageway forming member 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; and

the first passageway forming member including at least one connecting recess that opens into the first and second passageways formed by the first passageway forming member, the first end of the second passageway forming member being receivable in the connecting recess, such that the inlet and outlet of the second passageway forming member open into the at least one passageway formed by the first forming member when the first end of the second passageway forming member is received in the connecting recess.

2. The system of claim 1 wherein each of the first and second passageway forming members also includes at least a first plug insert secured to the second end of each passageway forming member to block the at least one passageway at the second end.

3. The system of claim 1 further including a plurality of elastomeric seals and a plurality of mechanical fasteners, the mechanical fasteners to mechanically fasten the first passageway forming member and the second passageway forming member together;

and

wherein the first passageway forming member input port, at least one of the plurality of elastomeric seals, and the second passageway forming member output port are arranged in substantial structural alignment with each other such that the at least one of the plurality of elastomeric seals is positioned between and in substantial contact with both the first passageway forming member and the second passageway forming member to create a sealed flow path between the first passageway forming member input port and the second passageway forming member output port.

4. The system of claim 1 wherein the first passageway forming member includes a plurality of connecting recesses that open into the first and second passageways formed by the first passageway forming member, and wherein each of the connecting recesses can receive a first end of a second passageway forming member so that the inlet and outlet of the received second passageway forming member opens into the first and second passageways formed by the first passageway forming member.

5. The system of claim 1 wherein at least a subset of the first and second passageway forming members form a single passageway and include both an inlet and an outlet that open into the single passageway.

6. The system of claim 1 wherein the passageways are formed along lengths of the first and second passageway forming members, and wherein the first and second passageway 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 passageway forming members into at least one of the passageways.

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

8. The system of claim 1 to cool at least one electrical component, the electrical component including a coil having a plurality of turns disposed over at least one of the first and second passageway forming members.

9. The system of claim 1 wherein the first passageway forming member includes a circular recess in the first external surface and wherein the at least one elastomeric seal is placed in the circular recess.

10. The system of claim 9 wherein the elastomeric seal comprises an elastomeric O-ring.

11. The system of claim 1 wherein the first passageway forming member includes first and second passageways.

12. The system of claim 11 wherein the inlet and outlet of the second passageway forming member open into the first and second passageways formed by the first forming member.

13. The system of claim 12 wherein the first forming member includes an inlet that opens into the first passageway formed by the first passageway forming member and an outlet that opens into the second passageway formed by the first forming member, and wherein the first and second passageways are completely separate.

14. The system of claim 13 wherein the first passageway 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.

15. The system of claim 1 wherein the first end forms a cylindrical connection head portion through which the first and second passageways pass.

16. A cooling system comprising:

a first passageway forming member including first and second ends and at least one connecting recess that opens into first and second passageways formed by the first passageway forming member; and

a second passageway forming member including first and second ends and inlet and outlet ports proximate the first end such that the first end, including an elastomeric seal and the inlet and outlet ports, is sealably insertable in and removable from the at least one connecting recess, where the inlet port opens into the first passageway and the outlet port opens into the second passageway, and where, when the first end is inserted in the at least one connecting recess, the elastomeric seal is sandwiched between and in substantial contact with both the first end and the first passageway forming member.

17. The system of claim 16 wherein at least one of the first and second passageway forming members are substantially rectilinear in cross section.

18. The system of claim 16 further including a plurality of mechanical fasteners to mechanically fasten the first forming member and the second forming member together.

19. The system of claim 16 wherein the second passageway forming member includes first and second passageways, and each of the first and second passageway forming members also includes at least a first plug insert secured to the second end of each passageway forming member to block the first and second passageways at the second end.
