Patent number: 11197394Abstract: Apparatuses and methods are provided for blocking removal of an air-moving assembly from a housing when in operational state. The apparatus includes a protective louver assembly having a louver(s) and an interlock element(s). The louver(s) is disposed at an air inlet or an air outlet of the air-moving assembly, and pivots between an operational and a quiesced orientation, dependent on presence or absence, respectively, of airflow through the air-moving assembly. The interlock element(s) is associated with the louver(s) to pivot with the louver(s) between the operational orientation and the quiesced orientation. In the operational orientation, the interlock element(s) blocks, at least in part, access to at least one fastener securing the air-moving assembly within the housing, and thereby prevents removal of the air-moving assembly from the chassis when in the operational state.Type: GrantFiled: November 22, 2017Date of Patent: December 7, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Levi A.

Patent number: 11147190Abstract: Apparatuses and methods are provided for protectively covering an air inlet or outlet of an air-moving assembly. The apparatus includes a protective cover assembly, which includes a retractable cover and a spring-biasing mechanism. The retractable cover transitions between a retracted state, when the air-moving assembly is operatively positioned within the chassis, and in extended state, when the air-moving assembly is withdrawn from the chassis. In retracted state, the retractable cover is retracted away from the air inlet or outlet, and in extended state, the retractable cover covers, at least partially, the air inlet or outlet. The spring-biasing mechanism is coupled to the retractable cover and biases the retractable cover in the extended state when the air-moving assembly is withdrawn from the chassis, and compresses to allow transition of the retractable cover to the retracted state as the air-moving assembly is inserted into operative position within the chassis.Type: GrantFiled: January 14, 2019Date of Patent: October 12, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Levi A.

Patent number: 10753236Abstract: Systems and methods are provided for data center cooling by vaporizing fuel using data center waste heat. The systems include, for instance, an electricity-generating assembly, a liquid fuel storage, and a heat transfer system. The electricity-generating assembly generates electricity from a fuel vapor for supply to the data center. The liquid fuel storage is coupled to supply the fuel vapor, and the heat transfer system is associated with the data center and the liquid fuel storage. In an operational mode, the heat transfer system transfers the data center waste heat to the liquid fuel storage to facilitate vaporization of liquid fuel to produce the fuel vapor for supply to the electricity-generating assembly. The system may be implemented with the liquid fuel storage and heat transfer system being the primary fuel vapor source, or a back-up fuel vapor source.Type: GrantFiled: September 20, 2019Date of Patent: August 25, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Levi A.
