Abstract

An example test system includes: a manifold including fluid channels, where the fluid channels are for holding coolant; a quick disconnect mechanically coupled to the manifold, where the quick disconnect includes a channel for passing coolant between a fluid channel and a test board; a containment plate mechanically coupled to the manifold, and a cover over at least part of the quick disconnect, where the cover is hermetically sealed to the quick disconnect and to the containment plate to thereby form a containment chamber.

Claims (53)

1. A test system comprising:

a manifold comprising fluid channels, the fluid channels for holding coolant;

a quick disconnect mechanically coupled to the manifold, the quick disconnect comprising a channel for passing coolant between a fluid channel and a test board;

a containment plate mechanically coupled to the manifold, the containment plate comprising one or more channels that connect the containment chamber to another containment chamber to thereby form a containment zone, the manifold comprising an output channel from the containment zone; and

a cover over at least part of the quick disconnect, the cover being hermetically sealed to the quick disconnect and to the containment plate to thereby form a containment chamber.

2. The test system of claim 1 , wherein the quick disconnect is a first quick disconnect, the cover is a first cover, and the containment chamber is a first containment chamber, and wherein the test system further comprises:

a second quick disconnect, the second quick disconnect being mechanically coupled to the manifold, the second quick disconnect comprising a channel for passing coolant between a fluid channel and the test board, and

a second cover over at least part of the second quick disconnect, the second cover being hermetically sealed to the second quick disconnect and to the containment plate to thereby form the other containment chamber, the other containment chamber being a second containment chamber.

3. The test system of claim 2 , wherein the one or more channels connect the first containment chamber and the second containment chamber to thereby form the containment zone.

4. The test system of claim 3 , further comprising:

a separator in fluid communication with the output channel, the output channel for transporting coolant and gas from the containment zone, the separator for separating the coolant from the gas.

5. The test system of claim 4 , wherein the separator comprises a helical insert tube.

6. The test system of claim 4 , further comprising:

a tube mechanically coupled to the separator for receiving the coolant;

a sensor to sense the coolant in the tube; and

a drain valve to drain the coolant from the tube.

7. The test system of claim 4 , further comprising:

a vacuum generator configured to reduce air pressure in the containment zone through suction;

wherein the vacuum generator is mechanically coupled to the separator so as to enable the gas to flow from the separator to the vacuum generator.

8. The test system of claim 7 , further comprising:

a pressure monitor for monitoring air pressure in the containment zone.

9. The test system of claim 2 , further comprising:

a compression plate for use in creating hermetic seals between the first cover and the containment plate and the second cover and the containment plate, at least part of the first cover and at least part of the second cover being between the compression plate and the containment plate, the compression plate comprising a mechanical connection to the containment plate for tightening the compression plate against the containment plate.

10. The test system of claim 1 , wherein the cover includes silicone and the coolant includes water.

11. A test system comprising:

a structure comprising a return channel and a supply channel, the supply channel for providing liquid coolant to a test board and the return channel for receiving liquid coolant from the test board;

a first quick disconnect in fluid communication with the supply channel;

a first cover over at least part of the first quick disconnect, the first cover being hermetically sealed to the first quick disconnect and to the structure to thereby form a first containment chamber;

a second quick disconnect in fluid communication with the return channel; and

a second cover over at least part of the second quick disconnect, the second cover being hermetically sealed to the second quick disconnect and to the structure to thereby form a second containment chamber;

wherein the structure comprises an output channel in fluid communication with both the first containment chamber and the second containment chamber;

wherein the structure comprises:

a manifold comprising the return channel and the supply channel; and

a containment plate mechanically coupled to the manifold, the containment plate comprising a fluid seal that is around the first quick disconnect and the second quick disconnect, the containment plate comprising one or more channels that connect the first containment chamber to the second containment chamber to thereby form a containment zone to which the output channel is in fluid communication.

12. The test system of claim 11 , further comprising:

a compression plate for use in creating hermetic seals between the first cover and the containment plate and the second cover and the containment plate, at least part of the first cover and at least part of the second cover being between the compression plate and the containment plate, the compression plate comprising a mechanical connection to the containment plate for tightening the compression plate against the containment plate.

13. The test system of claim 11 , wherein further comprising:

a separator in fluid communication with the output channel, the output channel for transporting liquid coolant and gas from at least one of the first containment chamber and the second containment chamber, the separator for separating the liquid coolant from the gas.

14. The test system of claim 13 , wherein the separator comprises a helical insert tube.

15. The test system of claim 14 , wherein the tube comprises an optical sensor to detect liquid in the tube.

16. The test system of claim 13 , further comprising:

a tube mechanically coupled to the separator for receiving the liquid coolant;

a sensor to sense the liquid coolant in the tube; and

a drain valve to drain the liquid coolant from the tube.

17. The test system of claim 13 , further comprising:

a vacuum generator configured to reduce, through suction, air pressure in the first containment chamber and in the second containment chamber;

wherein the vacuum generator is mechanically coupled to the separator so as to enable the gas to flow from the separator to the vacuum generator.

18. The test system of claim 17 , further comprising:

a pressure monitor for monitoring air pressure in the containment zone.

19. The test system of claim 11 , wherein the first cover and the second cover each includes silicone and the liquid coolant is water.

20. The test system of claim 11 , further comprising:

additional quick disconnects in fluid communication with the supply channel; and

additional quick disconnects in fluid communication with the return channel.
