Dielectric liquid immersion cooling container
An immersion-cooling container for single-phase liquid dielectric immersion cooling. The container has a tank and a liner, which mate together to form a sealed inflow channel and one or more sealed outflow channels. The liner and the support base comprise one or more vents to permit passage of dielectric liquid to envelop and cool equipment disposed inside the container. The liner sidewalls define one or more flow channels that promote passage of the liquid coolant from the container and into the outflow channels, thereby enabling continuous circulation of the dielectric liquid.
1. An immersion-cooling apparatus, comprising:
a tank having a bottom and one or more walls at least partially enclosing a first interior volume, the tank further having an interior surface;
a liner disposed within the first interior volume of the tank, the liner having an exterior surface and a second interior volume configured to retain an object therein;
an inflow channel defined within the first interior volume of the tank and disposed between the tank and the liner;
an inlet fluidly coupled to the tank and disposed in fluid communication with the inflow channel;
an outflow channel defined within the first interior volume of the tank, wherein the outflow channel is at least partially disposed between the bottom of the tank and the exterior surface of the liner;
an outlet fluidly coupled to the tank and disposed in fluid communication with the outflow channel;
a divider disposed on the interior surface of the tank, the exterior surface of the liner, or both, wherein the divider partitions at least a portion of the first interior volume of the tank into the inflow channel and the outflow channel; and
a vent aperture disposed within the liner, wherein the vent aperture is in fluid communication with the inflow channel, thereby enabling the dielectric liquid to enter into the second interior volume of the liner via the vent aperture.
2. The immersion-cooling apparatus of claim 1 , wherein the inlet or the outlet are fluidly coupled to the bottom of the tank.
3. The immersion-cooling apparatus of claim 1 , wherein the inlet or the outlet are fluidly coupled to the one or more walls of the tank.
4. The immersion-cooling apparatus of claim 1 , wherein the inflow channel is defined between a bottom of the tank and the exterior surface of the liner.
5. The immersion-cooling apparatus of claim 1 , further comprising a down-flow channel defined within a space between the exterior surface of the liner and the interior surface of the one or more walls of the tank, the down-flow channel providing a passage for the dielectric fluid to the outflow channel upon exiting the second interior volume of the liner.
6. The immersion-cooling apparatus of claim 5 , wherein a flow regulator is disposed within the down-flow channel, the flow regulator configured to reduce air bubble entrainment within the dielectric liquid.
7. The immersion-cooling apparatus of claim 5 , wherein the inlet or the outlet are fluidly coupled to the bottom of the tank.
8. The immersion-cooling apparatus of claim 5 , wherein the inlet or the outlet are fluidly coupled to the one or more walls of the tank.
9. The immersion-cooling apparatus of claim 5 , wherein the inflow channel is defined between a bottom of the tank and the exterior surface of the liner.
10. The immersion-cooling apparatus of claim 5 , further comprising a ledge disposed on the interior surface of the one or more walls of the tank, wherein the ledge, the interior surface of the one or more walls of the tank, and the exterior surface of the liner collectively define the down-flow channel.
11. The immersion-cooling apparatus of claim 10 , wherein the ledge has a downward slope directing the dielectric liquid to flow toward the outlet.
12. The immersion-cooling apparatus of claim 5 , wherein the exterior surface of the liner is at least partially disposed in an abutting contact with the one or more walls of the tank, forming a liquid-impermeable seal at an interface thereof.
13. The immersion-cooling apparatus of claim 5 , wherein the liner has one or more corrugations defining the down-flow channel.
14. The immersion-cooling apparatus of claim 5 , wherein the tank has one or more corrugations defining the down-flow channel.
15. The immersion-cooling apparatus of claim 5 , wherein the dielectric fluid enters the down-flow channel upon overflowing the liner.
16. The immersion-cooling apparatus of claim 1 , wherein the exterior surface of the liner is at least partially disposed in an abutting contact with the one or more walls of the tank, forming a liquid-impermeable seal at an interface thereof.
17. The immersion-cooling apparatus of claim 1 , wherein the divider comprises a ridge.
18. The immersion-cooling apparatus of claim 1 , further comprising a support base configured to be disposed inside the liner, wherein the support base has a plurality of apertures configured to permit the dielectric fluid to flow therethrough.
19. The immersion-cooling apparatus of claim 1 , wherein the liner has a first sidewall and a second sidewall, and wherein the first sidewall is lower than the second sidewall.
