Wind turbine generator water cooling system with heat dissipation plate convenient to replace

The invention provides a wind turbine generator water cooling system with a heat dissipation plate convenient to replace, relates to the technical field of wind turbine generators, and aims to solve the problem that a heat dissipation plate on an existing wind turbine generator is inconvenient to replace and maintain. The water cooling plate is connected with a heat dissipation plate through a connecting mechanism, a second cooling pipeline is arranged in the heat dissipation plate, the second cooling pipeline is communicated with the first cooling pipeline, a plurality of heat dissipation fins are further arranged on the heat dissipation plate, and the water cooling plate is connected with the heat dissipation plate through the connecting mechanism. A cooling pipeline in the heat dissipation plate is communicated with a cooling pipeline between the water cooling plates, so that the contact area between cooling liquid and the external environment is increased, and the cooling efficiency is improved; a sealing
