A liquid-cooling heat sink includes a base, a cover and a heat exchanger. The cover has an intake pipe and an exhaust pipe. The heat exchanger includes heat-dissipating plates overlapping with each other. Each heat-dissipating plate has dividing strips. Any two adjacent dividing strips define a through-hole. Both ends of each heat-dissipating plate are provided with a notch respectively. Each heat-dissipating plate overlaps with adjacent one heat-dissipating plate in a head-to-tail manner, so that the two notches of each heat-dissipating plate form an intake notch channel and an exhaust notch channel respectively. The dividing strips form an intersecting structure on upper and lower sides of each through-hole respectively to thereby define a multi-direction sub-channel. The cooling liquid flows from the intake notch channel into the multi-direction sub-channels and exits via the exhaust notch channel. In this way, the heat-exchanging efficiency and heat-dissipating effect are improved. |
