Disclosed is heat dissipation device with circulating liquid coolant. The device comprises a liquid pump; a cooling unit mounted on a heat source of a high power electronic chipset, the cooling unit comprising passages for permitting coolant to pass through, each passage comprising a plurality of recessed and raised portions; a heat sink; and a pipe containing pressurized coolant, the pipe being passed through the liquid pump, the passages of the cooling unit, and the heat sink for forming a closed cooling loop. The recessed and the raised portions in the passage are capable of increasing fluid mixing or turbulence and vortex of coolant, generating a secondary swirling flow by different attack angles of coolant, and generating a chaotic advection at each of a plurality of flow passage when the liquid pump generates the adequate pulsating pressure waves, thereby carrying away heat generated by the high power electronic chipset and circulating coolant through the passages and dissipated at the heat sink.
