The invention belongs to the technical field of automobile electric drive system cooling, and particularly relates to an integrated electric drive system cooling structure and an integrated electric drive system. The integrated electric drive system cooling structure comprises a motor assembly. The motor assembly comprises a rotating shaft and a cooling pipe with an inner hole; the rotating shaft is provided with a mounting hole into which the cooling pipe is inserted; an annular water channel is formed between the outer wall of the cooling pipe and the inner wall of the mounting hole; and the inner hole and the annular water channel form a rotor cooling water channel. According to the integrated electric drive system cooling structure, the rotor cooling water channel is formed by the inner hole and the annular water channel, the heat dissipation efficiency of the integrated electric drive system cooling structure is improved, and the service life of the motor assembly is prolonged.
