Patent number: 11977423Abstract: Methods and systems for thermal management of hardware resources that may be used to provide computer implemented services are disclosed. The disclosed thermal management method and systems may improve the likelihood of data processing systems providing desired computer implemented services by improving the thermal management of the hardware resources without impairment of storage devices. To improve the likelihood of the computer implemented services being provided, the systems may proactively identify whether storage devices subject to impairment due to dynamic motion are present. If such storage devices are present, then the system may automatically take action to reduce the likelihood of the storage devices being subject to dynamic motion sufficient to impair their operation.Type: GrantFiled: December 20, 2021Date of Patent: May 7, 2024Assignee: Dell Products L.P.Inventors: Hung-Pin Chien, Jyh-Yinn Lin, Yu-Wei Chi Liao, Chien Yen Hsu, Ming-Hui Pan

Patent number: 11700706Abstract: A riser of an information handling system having an adjustable baffle that blocks air flowing through the riser from by-passing components of an expansion card, such as a PCIe card, installed in the riser. The baffle directs the flowing air across components of the expansion card to lower the operating temperature of the expansion card by convection. In some embodiments, part of the baffle is coupled to an angled slot of the riser body and another part of the baffle is coupled to a card holder so that movement of the card holder automatically adjusts the position of the baffle to direct otherwise by-passing air toward the components of the installed expansion card.Type: GrantFiled: October 8, 2020Date of Patent: July 11, 2023Assignee: Dell Products L.P.Inventors: Chuan Chieh Tseng, Ming-Hui Pan

Patent number: 11151978Abstract: A fan noise cancellation device comprises a base with a resonant ring formed with a plurality of resonance channels and a cover coupled to the base. Each resonance channel comprises an inner channel and an outer channel. Each inner channel has an opening to the resonant ring and has a length corresponding to a frequency. A baffle positioned in each inner channel determines an effective length of the inner channel. The inner channel baffles are coupled to the cover, wherein rotation of the cover relative to the resonance ring changes the position of the inner channel baffles to change the effective lengths of the inner channels to adjust the fan noise cancellation waveform frequency. Vanes on the cover are positioned in an airflow such that the airflow rotates the cover, and a spring in each resonance channel counteracts the rotation to adjust the inner channels.Type: GrantFiled: November 19, 2020Date of Patent: October 19, 2021Assignee: Dell Products L.P.Inventors: Chun-Fa Tseng, Ming-Hui Pan, Jyh-Yinn Lin, Hung-Wen Wu
