Water-cooled radiator for range extender unit

The utility model relates to a water-cooling radiator for a range extender unit, which comprises a water tank frame, an engine radiator water tank, a generator radiator water tank and a range extender controller, the engine radiator water tank and the generator radiator water tank are arranged in parallel in the water tank frame to form a radiating assembly module, and a fan cover is arranged on the radiating assembly module. A cooling fan is arranged in the fan cover, and a filter screen is arranged on the windward side of the fan cover. The utility model has the beneficial effects that the engine radiator water tank and the generator radiator water tank are arranged in parallel, so that the structure is compact, the volume is small, one radiating fan is shared, and the wind resistance is small; heat emitted by the two radiators cannot radiate each other, so that the cooling effect is better; the engine heat dissipation water tank and the generator heat dissipation water tank are each provided with a water l
