  • Patent number: 11324146
    Abstract: A kit for forming a data center comprising a first rack, a second rack, a first support having a first end and a second end opposite the first end, the first support configured to be secured to the floor at the first end, a cooling frame having a cooling unit received therein, the cooling frame having a first face and a second face opposite the first face, the cooling frame configured to be secured to the second end of the first support, a first distribution frame having a first plurality of support arms extending therefrom, the first distribution frame configured to be coupled to the first face of the cooling frame, and a second distribution frame having a second plurality of support arms extending therefrom, the second distribution frame configured to be coupled to the second face of the cooling frame.

  • Patent number: 8994339
    Abstract: A dual-loop control configuration employs battery temperature as a feedback metric in order to prevent overheating when recharging batteries. Temperature sensors are used to obtain the battery temperature. Depending on the battery temperature that is measured, a processing device such as a battery interface module determines whether that temperature exceeds a temperature threshold. The processing device also determines a charge rate of the batteries. The processing device is configured to vary the fan speed to increase or decrease airflow for cooling the batteries based on this information, and also regulates the charge rate of the batteries as a function of the fan speed. This arrangement may be used as part of a battery backup system, such as in an uninterruptible power supply used in a data center. Alternatively, it may be used in the power supply system of an electric vehicle. Fluids besides air may also be employed.

  • Patent number: 8576560
    Abstract: Aspects of the invention include a method and apparatus for cooling a hard drive in a hard drive array. In one example, the cooling device has similar dimensions as a hard drive on a server. Within the cooling device is a fan. The positioning of the fan provides both impingement and indirect airflow on a hard drive. The cooling device may also have power and data connections identical to those of the hard drive. These connections allow the cooling device to be connected and controlled by a control unit. The control unit may operate to monitor and control the temperature of the hard drive by controlling the power and speed of the fan. In another example, the cooling device is operable to cool DIMMs on a circuit board.

  • Patent number: 8344246
    Abstract: Aspects of the invention pertain to cooling bundles of power distribution cables or other current carrying cables. Such cables give off heat, especially when carrying high current loads. One or more cooling members are used to secure multiple cables. The cables may be placed about a generally circular shaped member which has a central opening. Receptacles are placed along an outer perimeter of the cooling member to secure the cables. The thickness of each cooling member may vary. When multiple cooling members are used, they may be spaced at least 6 inches apart. The cooling members may be fabricated from a nonconductive material such as PVC.
