Abstract: A water block of a double-layered radiating water-cooling radiator includes a first heat exchange area, a second heat exchange area, a motor, a first connecting pipe, a second connecting pipe and a radiating module. A cooling liquid enters the first heat exchange area from a first water inlet of the first heat exchange area, flows through the first heat exchange area, the first connecting pipe, the second heat exchange area and the second connecting pipe in sequence, flows out from a first water outlet of the first heat exchange area, flows into a water inlet of a radiating bar, flows out from a water outlet of the radiating bar, and flows into the first water inlet of the first heat exchange area, thereby forming a cooling cycle. Whereby the water block of a double-layered radiating water-cooling radiator disclosed by the present invention improves the radiating efficiency greatly.
