The invention relates to a micro-channel heat dissipation device with a vortex generator and a reentry cavity. The micro-channel heat dissipation device is mainly composed of a heat source 1, a cover plate 2, the vortex generator 3 and a micro-channel bottom plate 4 with the reentry cavity. The vortex generator is mainly characterized in that the vortex generator with good thermal conductivity can generate vortexes, improve fluid mixing, enhance heat exchange capacity, guarantee good flow resistance characteristics and effectively enhance mixing and heat transfer effects of cooling media. The cover plate is connected with the channel bottom plate through brazing, so that the overall sealing performance is improved; and meanwhile, reentry cavity structures are designed on the two side wall surfaces of the rectangular straight channel and are used for compensating the pressure drop and improving the flowing property. The heat exchanger is compact in structure, good in heat exchange capacity and clear in functio
