Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of liquid cooling systems, in particular to an integrated liquid cooling system. Background Art
[0002] With the rapid development of energy storage technology, especially the significant increase in the scale and energy density of energy storage containers, systems face increasingly severe heat dissipation challenges while maintaining efficient operation. The significant heat generated during battery charging and discharging can directly impact battery performance, lifespan, and even safety if this heat is not effectively managed. Therefore, the use of liquid cooling temperature control systems is crucial to ensure environmental stability within energy storage containers and temperature uniformity across battery packs.
[0003] Currently, a Chinese invention patent with publication number CN118398964B discloses an AI-powered dynamic-control liquid-cooling integrated system, an energy storage power station, and a control method. This liquid-cooling integrated system uses two or more chillers to simultaneously serve multiple energy storage containers. The addition of a cooling tower and an AI dynamic control module enables the dynamic combination of cooling towers and chillers, improving the system's overall energy efficiency and reducing long-term operating costs. However, there are some problems with directly using traditional dry cooling towers in this liquid-cooling integrated system.
[0004] Specifically, the design of a traditional dry cooling tower is usually to have air intake at the side of the bottom of the tower and air outlet from the fan at the top. The heat exchanger is set below the fan, and the fan blows directly at the heat exchanger. When the air flows through the heat exchanger, it will encounter greater resistance. High wind resistance will cause the fan to consume more energy to push the air flow, thereby increasing the energy consumption of the system. At the same time, high wind resistance will also limit the air flow rate and may also hinder the effective contact between the air and the cooling water, affecting the heat exchange efficiency. In some extreme cases, if the wind resistance is too large, it may cause poor air circulation in some areas, which will greatly reduce the cooling effect of these areas and fail to meet the strict temperature control requirements of the liquid cooling integrated system.
