Abstract
A thermal management system for cooling electronics includes an immersion tank, a working fluid in the immersion tank, a heat exchanger, a first fluid conduit, and a second fluid conduit. The heat exchanger is configured to transfer thermal energy from the working fluid to ambient air to cool the working fluid. The first fluid conduit provides fluid communication from the immersion tank to the heat exchanger, and the second fluid conduit provides fluid communication from the heat exchanger to a spray nozzle to spray working fluid into the immersion tank.
Claims20
A thermal management system comprising:
- an immersion tank;
- a working fluid at least partially positioned in the immersion tank, wherein the working fluid provides an immersion bath configured to have a heat-generating component at least partially immersed therein;
- a heat exchanger configured to transfer thermal energy from the working fluid to ambient air to cool the working fluid;
- a first fluid conduit providing fluid communication from the immersion tank to the heat exchanger;
- and
- a second fluid conduit providing fluid communication from the heat exchanger to a spray nozzle to spray working fluid into a headspace of the immersion tank above the immersion bath, the spray of working fluid configured to condense at least a portion of a vapor phase of the working fluid into the immersion bath.
A thermal management system comprising:
- an immersion tank;
- a working fluid at least partially positioned in the immersion tank, wherein the working fluid provides an immersion bath configured to have a heat-generating component at least partially immersed therein;
- a heat exchanger configured to transfer thermal energy from the working fluid to ambient air to cool the working fluid;
- a first fluid conduit providing fluid communication from the immersion tank to the heat exchanger;
- a second fluid conduit providing fluid communication from the heat exchanger to a spray nozzle to spray working fluid into the immersion tank, wherein the spray nozzle is positioned on a side of the immersion tank, and wherein the spray of working fluid is configured to condense at least a portion of a vapor phase of the working fluid into the immersion bath;
- at least one sensor to measure a temperature of the working fluid;
- a fan configured to flow air through the heat exchanger;
- a fluid pump positioned in-line in the first fluid conduit or the second fluid conduit;
- and
- a logic controller in data communication with the at least one sensor and with the fan and the fluid pump to adjust the fan or fluid pump in response to a measured temperature of the working fluid.
