Abstract: A liquid-cooled plate radiator is disclosed. The liquid-cooled plate radiator includes a radiator body. A coolant liquid runner for circulating a coolant liquid is formed inside the radiator body. The coolant liquid runner includes a plurality of radiating sub-runners. Then, a plurality of fin units are arranged on the radiating sub-runners along a flow direction of the coolant liquid. The fin unit has a plurality of fins extending side by side along the flow direction of the coolant liquid. Moreover, the fins of the front and rear adjacent fin units on the radiating sub-runners are staggered, thereby increasing the radiating area, enhancing the disturbance of the coolant liquid when flowing inside the radiating sub-runners, and improving the radiating efficiency. Thus, the technical problems of limited radiating area and low radiating efficiency caused by a single linear coolant liquid runner are solved.
