Abstract
A cold plate assembly for cooling heat-generating electrical component on a circuit board is disclosed. The cold plate assembly includes a cold plate with a bottom contact surface to thermally contact the heat-generating electrical component. The cold plate has an inlet coupler on an opposite top surface to receive coolant; an internal conduit to circulate the received coolant; and an outlet coupler on the opposite top surface to return the coolant. A flexible metal inlet tube is fluidly connected to the inlet coupler to supply coolant. A flexible metal outlet tube is fluidly connected to the outlet coupler to return coolant.
Claims15
A cooling system comprising:
- an inlet manifold for delivering coolant at a first temperature;
- an outlet manifold for receiving the coolant at a second temperature that is higher than the first temperature;
- a first fluidic circuit between the inlet manifold and the outlet manifold, the first fluidic circuit comprising:
- a first flexible metal tube couplable to one of the inlet manifold and the outlet manifold;
- a rigid metal tube more rigid than the first flexible metal tube, the rigid metal tube having:
- one end connected to the first flexible metal tube;
- and
- an open end opposite to the one end, the open end including an annular shoulder, the annular shoulder having a sloped interior surface that transitions to a flat circular shoulder end surface and a side opposite to the sloped interior surface;
- a first cold plate couplable to a first heat-generating electrical component, the first cold plate connected to the open end of the rigid metal tube;
- the first cold plate including a connector assembly for receiving or providing the coolant from the rigid metal tube, the connector assembly comprising:
- a coupler having an interior chamber, the interior chamber having:
- a threaded interior surface;
- and
- a circular sloped surface;
- a screw member having:
- an exterior threaded surface mateable with the threaded interior surface of the interior chamber of the coupler;
- and
- a through bore allowing the rigid metal tube to pass through the screw member, the through bore including a sloped exterior surface;
- wherein when the sloped exterior surface of the screw member presses the side of the annular shoulder of the rigid metal tube as the exterior threaded surface of the screw member and the threaded interior surface of the coupler engage each other, the sloped interior surface of the rigid metal tube is configured to crimp between the sloped exterior surface of the screw member and the circular sloped surface of the coupler to create a fluid seal between the rigid metal tube and the coupler;
- and
- a second flexible metal tube couplable to the first cold plate and another of the inlet manifold and the outlet manifold.
