The invention provides a highly integrated train fresh air inlet device. The device is characterized in that a snow melting device is arranged between an air conditioning unit fresh air grid and a pressure wave valve plate, the snow melting device comprises a plurality of rainwater separation structures with a rainwater separation function, heating pipes are arranged in the rainwater separation structures, back plates with holes are arranged on the rear portions of the rainwater separation structures; a bottom plate is arranged at the bottom, and a circular drain hole 9 is formed in the bottomplate and used for draining separated rainwater; fresh air passes through the snow melting device from the outside, rainwater separation is carried out, the fresh air is heated, and the separated rainwater is discharged through the circular drain hole in the bottom plate. The snow melting device is provided with a temperature switch, the snow melting device is prevented from losing efficacy due to overheating, the snow melting device is integrated in the fresh air inlet device, modular design is achieved, and the integration degree is high. A mature and reliable electric heating pipe type heating mode is selected, the occupied space is small, and reliability is high.
