Energy storage battery systems feature large capacity and high power, accompanied by uneven internal temperature distribution, imposing stringent thermal management requirements on the systems. Thermal control is closely correlated with system stability, operational efficiency and service life. Liquid cooling represents the optimal cooling solution for energy storage systems. Our flat zero-spillage quick-disconnect couplings and full-flow interlock ball valve couplings in large sizes are capable of meeting the reliability demands of energy storage liquid cooling systems.
