Power supply internal function module air duct structure

The utility model discloses a functional module air duct structure in a power supply, which relates to the technical field of power box heat dissipation and comprises a heat dissipation power box, a processing plate heat dissipation frame is arranged at the bottom end in the heat dissipation power box, and a lower side air duct cavity is arranged on the bottom side in the heat dissipation power box and the processing plate heat dissipation frame. And an upper side air duct cavity is formed in the top side of the interior of the heat dissipation power box and the treatment plate heat dissipation frame, and a storage battery body is arranged on the portion, located on the heat dissipation power box, of the inner side of the lower side air duct cavity. When the air duct heat dissipation fan is powered on to work, air in the front is adsorbed to be exhausted for heat dissipation, and the adsorbed air moves upwards when passing through the treatment plate heat dissipation frame, so that heat at the treatment panel
