  • Patent number: 11212940
    Abstract: The present document describes a passive thermal-control structure for speakers and associated apparatuses and methods. The architecture of the passive thermal-control structure is such that heat is transferred from electronic subsystems of the electronic speaker device to the passive thermal-control structure, which acts as an internal, structural frame of the electronic speaker device and provides both thermal mitigation and structural stability. The passive thermal-control structure conducts heat from the electronic subsystems to a housing of the electronic speaker device. The housing of the electronic speaker device may dissipate the heat to the ambient environment to prevent thermal runaway of the electronic subsystems, and the internal frame mitigates the temperature of the housing from exceeding ergonomic temperature limits.

  • Patent number: 9013873
    Abstract: A container data center includes a container and a server cabinet received in the container. The server cabinet includes a rack and a number of heat dissipation devices mounted to a rear side of the rack. Each heat dissipation device includes a case fixed to the rack, a fan mounted to an outer side of the case, and a heat dissipation plate received in the case and aligning with the fan. The heat dissipation plate defines a vent. The fan draws heat air through the vent of the heat dissipation plate from the rack, and the heat air is cooled by refrigerant received in the heat dissipation plate to become cool air. The cool air flows in the container, and circularly flows into the cabinet from a front side of the cabinet.

  • Patent number: 8978747
    Abstract: A datacenter may use heat collected from a heat exchanger at the exhaust portion of a cooling system to heat inlet louvers for an atmospheric intake. The louvers may have fluid passages through which heated fluid may pass and cause the louvers to heat up. The heated louvers may operate during periods of snow, rain, high humidity, or other conditions to eliminate condensation, snow and ice buildup, or other problems. In some embodiments, a liquid may be passed through the louvers, while in other embodiments, heated air or other gas may be passed through conductive paths in the louvers. In a heated air system, holes in the louvers may allow the heated air to enter the incoming airstream to regulate the incoming temperature to the datacenter.

  • Patent number: 8943757
    Abstract: A data center module is a data center that can be prefabricated using generally standardized off-the-shelf components, and quickly assembled on a collocation site where a shared central facility is provided. The data center module is typically configured to be deployed with other identical data center modules around the central facility both in side-to-side and/or in back-to-back juxtapositions, typically without the need for interleaving space between adjacent modules in order to maximize real estate use. Each data center module typically comprises harden party walls, several floors for accommodating all the necessary electrical and cooling subsystems and for accommodating all the computing machinery (e.g. servers). Though all the data center modules share similar physical configuration, each data center module can be independently customized and operated to accommodate different needs.
