Claim 18:
19. A cooling system, comprising:
an immersion enclosure;
a distribution manifold coupled to the immersion enclosure, wherein the distribution manifold comprises:
one or more fluid outlets; and
a pump to distribute a two-phase fluid from the immersion enclosure to the one or more fluid outlets; and

a server enclosure within the immersion enclosure, wherein the server enclosure comprises:
one or more supply lines;
one or more fluid supply connectors coupled between the one or more fluid outlets of the distribution manifold and the one or more supply lines;
a server chassis configured to contain server electronics therein, wherein the server chassis is configured to be at least partially submerged in a two-phase immersion fluid; and
one or more cooling plates configured to be attached to the server electronics, wherein a cooling plate comprises:
an inlet port to receive the two-phase fluid from a fluid supply connector;
a base plate configured to be attached to the server electronics for cooling;
a plurality of heat spreading structures disposed and spaced apart on the base plate to extend a heat exchange area from the base plate; and
a plurality of fluid channels disposed on the base plate, wherein each of the plurality of fluid channels is inserted and secured between a pair of adjacent heat spreading structures, wherein each of the fluid channels comprises:
a channel inlet to receive at least a portion of the two-phase fluid from the inlet port,
a channel outlet to allow the received portion of the two-phase fluid to flow through and exit the corresponding fluid channel, and
one or more intermediate outlets disposed between the channel inlet and the channel outlet to allow at least a portion of the received two-phase fluid to exit the cooling plate either in a vapor form or a liquid form.
