Claim of US Patent No. 10,251,318

1. A cooling system comprising:a coolant loop comprising a coolant;
a heat exchange assembly coupled to the coolant loop to cool coolant within the coolant loop;
a coolant supply manifold coupled to the coolant loop;
a multifunction coolant manifold structure to deaerate the coolant, the multifunction coolant supply manifold structure being coupled to the coolant loop and being separate from the heat exchange assembly, the multifunction coolant supply manifold structure including:
a coolant-commoning manifold; and
an auxiliary coolant reservoir disposed above and in fluid communication with the coolant-commoning manifold; and
multiple cooling structures coupled to the coolant loop in parallel fluid communication between the coolant supply manifold and the coolant-commoning manifold to receive coolant from the coolant supply manifold, and exhaust coolant to the coolant-commoning manifold;
the multifunction coolant manifold structure comprising both the coolant-commoning manifold and a coolant distribution manifold portion integrated together in a single structure, and wherein the multifunction coolant manifold structure is sized larger than the coolant supply manifold;
wherein the multifunction coolant manifold structure deaerates the coolant by the coolant-commoning manifold being sized larger than the coolant supply manifold to slow therein a flow rate of coolant exhausting from the multiple cooling structures as the coolant enters the coolant-commoning manifold to allow gas within the exhausting coolant to escape the coolant within the coolant-commoning manifold, the escaping gas rising from the coolant-commoning manifold to the auxiliary coolant reservoir, and being replaced within the coolant-commoning manifold by coolant from the auxiliary coolant reservoir; and
wherein the multifunction coolant manifold structure is a single, integrated and rigid structure, and wherein the coolant-commoning manifold has a larger dimension in a first direction compared with that of the auxiliary coolant reservoir, and the auxiliary coolant reservoir has a larger dimension in a second direction compared with that of the coolant-commoning manifold.
