Abstract
A method and system for controlling operation of an immersion cooling system to filter a heat transfer fluid having an immersion cooling tank adapted to contain the heat transfer fluid used to immersion cool a heat-generating object contained therein, the method and system comprises: sampling the heat transfer fluid in the tank; measuring at least one property or parameter of the sampled heat transfer fluid; generating and transmitting measurement data to a control unit; comparing measurement data with respective threshold data using the control unit; and filtering the heat transfer fluid with a filter based on the comparison results of the control unit.
Claims20
An immersion cooling system for dissipating heat generated from at least one object immersed in an immersion cooling tank adapted to contain a heat transfer fluid, the system comprising:
- a testing unit containing at least one sensing device for measuring at least one property of the heat transfer fluid in the immersion cooling tank while the immersion cooling system is operating;
- the sensing device generates and transmits a signal representative of the measured property to a control unit, and
- wherein the control unit remediates the heat transfer fluid in the immersion cooling tank, the remediation is selected from a group consisting of shutting down the immersion cooling system to replace the heat transfer fluid;
- circulating the heat transfer fluid through a filter system;
- adding heat transfer fluid to the immersion cooling tank, and reducing power to at least one object being cooled during filtering of the heat transfer fluid, until the measured property is above a threshold value as determined by the control unit.
The system of claim of 1, wherein the heat transfer fluid is a two-phase electronic fluid with a boiling point below that of water.
A method of operating an immersion cooling system for dissipating heat generated from at least one object immersed in an immersion cooling tank adapted to contain a heat transfer fluid, the method comprising:
- sampling a volume of the heat transfer fluid in the immersion cooling tank while the object remains in an operating state;
- testing for at least one property of the heat transfer fluid in the immersion cooling tank while the immersion cooling system is operating;
- generating and transmitting a signal representative of the measured property to a control unit, and
- controlling the operation of a filter system to remediate the heat transfer fluid in the immersion cooling tank, the remediating is selected from a group consisting of shutting down the immersion cooling system to replace the heat transfer fluid;
- circulating the heat transfer fluid through a filter system;
- replenishing the heat transfer fluid, and reducing power to at least one object being cooled during filtering of the heat transfer fluid, until the measured property is above a threshold value as determined by the control unit.
