Patent number: 11737248Abstract: A data center cooling system has an indoor portion wherein heat is absorbed from components in the data center, and an outdoor heat exchanger portion wherein outside air is used to cool a first heat transfer fluid (e.g., water) present in at least the outdoor heat exchanger portion of the cooling system during a first mode. When an appropriate time has been reached to switch from the first mode to a second mode, the outdoor heat exchanger portion of the data cooling system is switched to a second heat transfer fluid, which is a relatively low performance heat transfer fluid (compared to the first fluid). It has a second heat transfer fluid freezing point, lower than the first heat transfer fluid freezing point, and sufficiently low to operate without freezing when the outdoor air temperature drops below a first predetermined relationship with the first heat transfer fluid freezing point.Type: GrantFiled: January 15, 2021Date of Patent: August 22, 2023Assignee: International Business Machines CorporationInventors: Madhusudan K.

Patent number: 11464137Abstract: A cooling system includes a device to be cooled and a cooling device integrated with the device to be cooled. A cooling volume has cavities and active coolant flow controls configured to adjust coolant flow through the cavities. A reservoir is in fluid communication with the cavities and has a liquid outlet and an inlet for a gas or gas-liquid mixture. A two-phase coolant is in the reservoir and cavities. The two-phase coolant has a phase transition temperature between an ambient temperature and an expected device temperature. A capacitance sensor is configured to determine a coolant capacitance in the cavities. A control module is configured to determine a vapor quality and void fraction of the coolant based on the measured capacitance and to increase coolant flow if the determined vapor quality and void fraction indicate a dry-out condition. A secondary cooling line removes heat from the cooling device.Type: GrantFiled: May 16, 2018Date of Patent: October 4, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Timothy J.
