Patent ID: 7738250

Claim:
A water-cooling radiator for a computer chip, the radiator using circulation of a coolant to improve heat dissipation, the radiator comprising: a body having a chip mounting surface, a plurality of parallelly arranged dissipating plates, and a plurality of parallelly arranged dissipating fins; an internal circulation flow path built inside the body to provide a passage required for the coolant to flow through, the internal circulation flow path comprising: a first communication region; a second communication region; a third communication region; one or more parallelly arranged dissipating flow paths enabling the coolant to flow through adjacent the chip mounting surface, the one or more dissipating flow paths having two ends respectively connected to the second communication region and the third communication region; and a plurality of parallelly arranged circulation branches connecting the first communication region and the third communication region; and a pump fixed to the side of the body near the computer chip to provide power to drive the coolant to flow, and to enable the first communication region to connect to the second communication region, wherein each of the plurality of parallelly arranged dissipating plates comprises two or more circulation branches.
