Zusammenfassung:	The utility model discloses a double-impeller hydraulic fan and a mining combined cabinet, relates to the technical field of heat exchange equipment, and solves the problems that in the prior art, two hydraulic fans are connected in series, so that a wind field is not uniformly distributed, and the heat exchange effect of the mining combined cabinet is influenced. The double-impeller hydraulic fan comprises a volute, a first impeller, a second impeller, a first fan blade and a second fan blade, the first impeller is rotatably connected with the first fan blade, the second impeller is rotatably connected with the second fan blade, and the first impeller and the second impeller are both installed in the volute. And the first impeller and the second impeller are driven by water flow entering the volute to rotate in the same direction. According to the double-impeller hydraulic fan, due to the fact that the first impeller and the second impeller rotate in the same direction, the first fan blade and the second fan
