  • Patent number: 10916818
    Abstract: A battery system can include an evaporation chamber and condenser. One or more battery cells can be immersed in a fluid where the battery cells and the fluid are housed in the evaporation chamber. The condenser can be fluid connected to the evaporation chamber through one or more vapor channels and one or more liquid channels. When the battery cells charge and discharge, heat dissipated by the battery cells is absorbed by the fluid, causing the fluid to change from liquid to vapor. The vapor travels through the one or more vapor channels into the condenser where the vapor changes back to liquid and returns to the evaporation chamber through the one or more liquid channels. The thermal management solution is a self-sensing and self-regulating system.

  • Patent number: 10897836
    Abstract: An airflow management system is utilized to manage airflows of a data center system, which has an efficient airflow arrangement, simplified and modularized building design, and high efficiency. The cold air and hot air are segregated. With wall supply and wall return mechanisms, the air flow is concentrated, distributed, and then concentrated again with simple management. The system substantially eliminates significant amount of air duct requirement and no return air plenum is needed. High efficiency results in less blower power consumption due to less airflow resistance and hot air recirculation is greatly reduced. The cold aisles and the hot aisles are completely separated as operators can enter and leave the cold aisles and hot aisles with minimal impacts. The system can be implemented in a modular manner and it is easy for heat recovery or reuse solution deployment in the hot air room.
