Abstract
An immersion cooled electronic arrangement includes a sealed housing, a coolant contained within the housing, and an electronic device submerged within the coolant. An agitator is disposed within the housing to control passive heat transfer between the electronic device and the coolant. An immersion cooling system and related method are also described.
Claims17
An immersion cooled electronic arrangement, comprising:
- a sealed housing;
- a coolant contained within the housing;
- an electronic device submerged within the coolant;
- an agitator disposed within the housing;
- a control module operatively connected to the agitator, the agitator is configured to control heat transfer between the electronic device and the coolant, the control module being responsive to non-transitory machine-readable instructions to control heat transfer between the electronic device and the coolant;
- and
- a sensor disposed within the housing, the sensor being adapted and configured to provide a signal including information relating to a heat transfer coefficient and critical heat flux between the electronic device and the coolant,
- wherein the instructions cause the control module to:
- determine a heat transfer coefficient between the electronic device and the coolant;
- compare the determined heat transfer coefficient with a predetermined heat transfer coefficient;
- and
- actuate the agitator based on the comparison of the determined heat transfer coefficient and the predetermined heat transfer coefficient.
