The invention relates to an electric-vehicle-mounted charger. The electric-vehicle-mounted charger is fixed into a spare tire pond. The portion between the spare tire pond and the electric-vehicle-mounted charger is filled with supporting parts, gaps are reserved between the supporting parts and the spare tire pond, and cooling loops where air can flow are formed by the gaps between the supporting parts and the spare tire pond. The electric-vehicle-mounted charger is arranged in a closed space of the spare tire pond of a vehicle, an air inlet passage connected with the exterior and an air outlet passage connected with the exterior are avoided, the space occupied by an external air passage is avoided, and meanwhile the development cost is effectively reduced. A cooling fan is integrated in the electric-vehicle-mounted charger, and the space additionally occupied by installing the fan in the external air passage is avoided; internal air cyclically flows along the metal plate wall of the spare tire pond, the aim that overall metal plates of the spare tire pond exchange heat with the exterior to achieve cooling is achieved, and the electric-vehicle-mounted charger is cooled under the sealed condition; and an air passage outlet, opened outwards, of an automobile body is not needed, the development cost is reduced, and water leakage risks caused by hole forming are avoided.
