Blind docking apparatus to enable liquid cooling in compute nodes
View Patent ↗An apparatus includes a rigid structure having first and second collars, a quick connect connector having first and second shoulders, and a spring biasing the connector toward an extended position with the first shoulder against the first collar and the second shoulder against the second collar. The first collar and the first shoulder form an inwardly and rearwardly angled contact surface there between, and the second collar and the second shoulder form an inwardly and rearwardly angled contact surface there between. The connector is centered in the first and second collars unless acted upon by a force overcoming the spring and pushing the connector to a retracted position with the first and second shoulders out of contact with the first and second collars. When retracted, the connector may adjust its position longitudinally, vertically, laterally or angularly to facilitate coupling with a mating fixed quick connect connector.

wherein, when the fourth quick connect connector is in a retracted position, the first compliant connector assembly allows the fourth quick connect connector to move in a lateral direction, vertical direction, longitudinal direction and at an angle relative to a longitudinal axis defined by an extended position of the fourth quick connect connector.
7. The apparatus of claim 1 , wherein the compute node includes a cooling circuit coupled between the third and fourth quick connect connectors.
8. The apparatus of claim 1 , wherein each of the quick connect connectors include an automatic shut off valve that prevent fluid flow when disconnected.
9. An apparatus comprising:
a compute node configured to be received within a chassis bay; and
a first compliant connector assembly secured to a rearward end of the compute node, wherein the first compliant connector assembly includes a rigid structure having first and second collars, a first quick connect connector having first and second shoulders, and a first spring biasing the first quick connect connector in the rearward direction, wherein the first collar and the first shoulder of the first compliant connector assembly form an inwardly and rearwardly angled contact surface there between, wherein the second collar and the second shoulder of the first compliant connector assembly form an inwardly and rearwardly angled contact surface there between, and wherein the first quick connect connector is oriented in a rearward direction for blind mating with a second quick connect connector within the chassis bay.
