Abstract

The disclosed computer cooling system includes a liquid immersion cooling tank configured as a server chassis with an integrated power bus, control bus and data bus. The server chassis tank receives and services a plurality of modular blades including disaggregated single server components dedicated to similar functions and resembling a beekeeper's box of vertical and spaced operation, insertion and extraction. The modular blades include at least one management blade, interfaces and peripherals blade, storage blade, CPU blade and one or more GPU blades and other processors. Each blade configures hottest operating components lowest in a heat flow via transverse mounted brackets and vented ends. A blade extraction mechanism includes movable winches for manipulating the plurality of modular blades from a top side of the heat flow and a hydraulic lift for pushing each modular blade from a bottom of the heat flow out of the liquid immersion cooling tank.

Claims (12)

1. A computer cooling system, comprising:

a) plurality of modular blades comprising at least one disaggregated management blade, interfaces and peripherals blade, storage blade, CPU blade and GPU blade, wherein each blade configures hottest operating components lowest in a coolest portion of a heat flow to optimize heat transfer;

b) a liquid immersion cooling tank configured as a single server chassis comprising a backplane having a power bus, a control bus and a data bus and configured to receive and service the plurality of modular blades resembling a beekeeper's box of vertical and spaced operation, insertion and extraction; and

c) a blade extraction mechanism comprising movable winches for manipulating the plurality of modular blades from a top side of the heat flow and a hydraulic lift for pushing each modular blade from a bottom of the heat flow out of the liquid immersion cooling tank,

wherein the ambient heat flows from a coolest and a lowest point to a hotter and a highest point in the liquid immersion cooling tank and in each of the plurality of modular blades and wherein the liquid immersion cooling tank aggregates the modular blades into the single server chassis.

2. The system of claim 1 , wherein the blade extraction mechanism comprises movable winches for manipulating the plurality of modular blades from the heat flow.

3. The system of claim 1 , wherein the blade extraction mechanism further comprises a hydraulic lift configured to push each modular blade from the heat flow and out of the liquid immersion cooling tank.

4. The system of claim 1 , further comprising a fluid pump and a heat exchanger and a fluid pump and a heat exchanger configured to remove heat from the heat flow in the liquid immersion cooling tank.

5. The system of claim 1 , further comprising a plurality of power supply components integral to the liquid immersion cooling tank and having disabled air fans to reduce a power consumption of the system.

6. The system of claim 1 , wherein the liquid immersion cooling tank further comprises double hull stainless steel walls to prevent corrosion and leakage of a liquid therein.

7. The system of claim 1 , further comprising a maintenance platform configured for drainage and access to the plurality of modular blades and the blade extraction mechanism.

8. The system of claim 1 , wherein the liquid immersion cooling tank further comprises an integrated temperature gauge, temperature alarm and RFID (radio frequency identification).
