The invention discloses a water-cooled frame and a generator, and relates to the technical field of motor cooling. A water-cooled frame includes a first mounting member, a second mounting member, anda frame body. The first mounting member and the second mounting member are welded to both ends of the frame body, respectively, and the first mounting member and the second mounting member are used for connecting to the motor. The main body of the frame is cylindrical and forms an installation space extending along the axis, the installation space is used for installing the motor core, a water flow passage is arranged in the side wall of the installation space, and the water flow passage is used for introducing the coolant which absorbs the heat inside the installation space. An electric generator adopts the water-cooled machine frame described above. The water-cooled machine base and the generator provided by the invention can meet the effective cooling effect, shorten the production cycle and save the research and development cost.
