Abstract: A cooling capacity distribution unit includes a liquid-cooled circulating pump disposed in a cabinet, and a frequency converter that supplies power to the liquid-cooled circulating pump. The frequency converter includes an AC-DC module and a DC-AC module. The AC-DC module is configured to be connected to mains, and the DC-AC module is connected to the liquid-cooled circulating pump. The cooling capacity distribution unit further includes a power supply unit, where the power supply unit includes a backup battery disposed in the cabinet, and a DC-DC module connected to the backup battery. The DC-DC module is connected to the DC-AC module and is configured to supply power to the liquid-cooled circulating pump.
