Assembly to provide thermal cooling
In one aspect, an assembly to provide thermal cooling includes a first member having a first channel configured to receive a cooling fluid, a second member having a second channel configured to receive the cooling fluid and a first plurality of hollow and flexible conduits connecting the first and second members. Each of the first plurality of hollow and flexible conduits is configured to provide a path for the cooling fluid to flow between the first and second channels.
1. An active, electronically scanned array (AESA) panel architecture system comprising:
a first daughter board comprising antenna elements;
a first thermal spreader attached to the antenna elements of the first daughter board;
a second daughter board comprising antenna elements;
a second thermal spreader attached to the antenna elements of the second daughter board;
a board assembly comprising:
a mother board; and
an RF interface board attached to the mother board and in direct contact with the first and second daughter boards;
a cold-plate assembly in direct contact with the first thermal spreader and the second thermal spreader and comprising:
a first cold-plate having a first channel configured to receive a cooling fluid;
a second cold-plate having a second channel configured to receive the cooling fluid and in direct contact with the first thermal spreader;
a third cold-plate having a third channel configured to receive the cooling fluid and in direct contact with the second thermal spreader;
a first plurality of hollow and flexible conduits connecting the first and second cold-plates, each of the first plurality of hollow and flexible conduits configured to provide a path for the cooling fluid to flow between the first and second channels; and
a second plurality of hollow and flexible conduits connecting the first and third cold-plates, each of the second plurality of hollow and flexible conduits configured to provide a path for the cooling fluid to flow between the first and third channels.
2. The system of claim 1 wherein at least one of the first plurality of hollow and flexible conduits is one of a flexible bellow, a hose or a sliding rigid tube.
3. The system of claim 1 , further comprising a boss attached to the first member and extending through the daughter card, the thermal spreader to the board assembly.
4. The system of claim 3 , wherein the boss includes threads, and further comprising a fastener secures the board assembly by engaging the threads of the boss.
5. The system of claim 1 , further comprising a spring disposed between the first and second cold-plates.
6. The system of claim 5 , wherein the first plate includes threads, and further comprising a fastener attaching the board assembly to the first cold-plate by engaging the threads on the first cold-plate.
