A flow passage structure for water-cooling device includes a heat-conductive main body provided with at least one flow passage, an inlet, and an outlet; and at least one vortex-forming section. The flow passage is provided in the heat-conductive main body and has a type of cooling liquid contained therein. The flow passage includes a channel portion and a top portion integrally connected to one another to ensure a leak-free flow passage. The at least one vortex-forming section is provided on one of the channel portion and the top portion for the cooling liquid flowing therethrough to form separated vortexes, so as to enable largely increased flow field turbulence in the flow passage and accordingly upgraded heat transfer performance of the cooling liquid.
