Study on spraying evaporative cooling technology for the large electrical machine

In order to solve the cooling problem of the large electrical machine under special situation, the staff of IEECAS brought forward new coolant and cooling structure for spraying evaporative cooling system based on experiences of evaporative cooling electrical machine for many years. The article discusses detailed the key problems include systems structure, theory calculation and experiment. By the running on the spot, it shows that the spraying evaporative cooling can be successfully used the large electrical machine. In addition it demonstrates that the heat transfer coefficients associated with spray cooling are very high compared to conventional heat transfer methods.
