针对矿用隔爆电机体积小、功率大、发热严重等应用特点,合理地设计水冷结构可以有效地平衡电机发热量,保证电机的安全运行。基于流体力学及电机传热学理论开发编制了水冷电机水路结构设计与温升计算程序。以YBSD矿用隔爆型三相电动机为研究对象,对其机壳水路进行了结构设计与热力计算,并进一步计算了电机的温升情况。通过将程序计算结果与实际电机数据进行对比分析,验证了所提方法的可行性和计算的准确性,为矿用隔爆型水冷电机设计提供了技术手段。

To make sure of the heating transfer and safe running of mine explosionproof motor which had special structure and applying situation such as small size, high power and terrible heat, it’s the key to design a rational and suitable watercooled structure. A program based on the heat transfer and hydrodynamic theory was compiled in this paper research on the watercooled structure and temperature rise of the YBSD motor. The calculation result was compared with the case and date from actual motor, then the feasibility and accuracy of the calculation method was verified, which provided a technological means.
