Abstract: Temperature rise is one of the key issues in the design of the generator. High parameters and low cost are the developing trend of the motor industry. In order to improve the heat dispersion of the motor and solve motor temperature rise, the design points of key parts in the cooler motor cooling system are explained in this paper. Based on the research of the cooler heat transfer principle and design, the basic design method of generator air-air cooler is concluded. Then, the cooler structure has been optimized. The company achieves good effects of decreasing cost and increasing benefit.
