The invention discloses a forced cooling type power distribution cabinet. The forced cooling type power distribution cabinet comprises a cabinet body; a cooling assembly which is capable of cooling the inner part of the cabinet body is mounted at the rear lower part of the cabinet body; the cooling assembly comprises a pump shell, two centrifugal fans which are coaxially and rotatably connected inthe pump shell and axes of which are along the horizontal direction, and a ring-shaped refrigeration sheet which is fixedly connected between the two centrifugal fan; a dehumidification box which isused for dehumidifying airflow pumped into one end of the cold centrifugal fan is rotatably mounted on one side of the pump shell; a rotation axis of the dehumidification box is parallel to the horizontal plane; water absorption resins are stored in the dehumidification box; a left air inlet pipe which is communicated with the center of the cold centrifugal fan is communicated with a part of a storage cavity; a hot air outlet pipe which is communicated with the periphery of the hot centrifugal fan is communicated with a part of the storage cavity; and the connection line of the left air inletpipe and the hot air outlet pipe forms an included angle with the horizontal plane. Through fixing the ring-shaped refrigeration sheet on the centrifugal fan, the temperature transfer efficiency can be accelerated when the centrifugal fan rotates.
