Abstract

The present invention discloses a coolant gallery structure fixedly connected with a motor stator. The coolant gallery structure comprises a case, a stator, a water-cooling flow channel and pipe joints, the water-cooling flow channel is a tubular structure, the tubular structure is provided with a liquid inlet, a liquid output and a helical water-cooling flow channel, the inner wall of the case isprovided with a location step, the water-cooling flow channel is arranged in the case, the bottom portion of the water-cooling flow channel is abutted against the location step, a stator penetrates the water-cooling flow channel, the stator is in interference fit with the water-cooling flow channel, and the two pipe joints both pass through the side wall of the case and are in corresponding threaded connection with the liquid outlet and the liquid inlet of the water-cooling flow channel. The water-cooling flow channel is taken as an independent part, prior to the stator coil being put into asilicon steel sheet groove, the stator coil is in interference fit with the silicon steel sheet groove, and the size of the water-cooling flow channel is approximate to the axial direction size of thestator so that the putting of the stator coil is not influenced.

Description

Technical field: [0001] The invention relates to a cooling water channel structure fixedly connected with a motor stator. Background technique: [0002] Circulating water cooling is a commonly used cooling method for motors. By setting flow channels on the motor casing, the cooling water can take away the heat transferred from the inside to the outer surface of the casing to achieve the purpose of cooling the stator. [0003] The runner is usually realized in the following ways: 1. Pre-buried the annular pipe before pouring the casing; 2. Obtained directly from the profile; 3. Processed a spiral water-cooled runner on the blank by means of material removal, and then Made of stitching. [0004] When the water-cooling channel is directly designed on the motor casing, the maximum outer circle of the end of the stator coil is required to be smaller than the inner diameter of the casing, and an appropriate amount of insulation distance should be reserved. For occasions where th...
