Abstract

A liquid-cooled heat dissipation device is disclosed, comprising a main body, a centrifugal pump, an inlet pipe and an outlet pipe. The main body comprises liquid flow channels and liquid storage tanks. The liquid flow channels are circumferentially arranged and spaced apart. The liquid storage tanks are located on both sides of the main body, and the liquid storage tanks on the same side are connected by liquid flow channels. The centrifugal pump is installed in one of the liquid storage tanks. The inlet pipe and the outlet pipe are in spatial communication with the other two liquid storage tanks, respectively. The centrifugal pump guides a cooling liquid through the inlet pipe, main body and outlet pipe. The cooling liquid travel through the liquid storage tanks via the liquid flow channels and forms radial jet flows after being pumped by centrifugal pump.
