Technical Electrodynamics| Summary: | Turbogenerators large and medium power cooling system disadvantages are identified. The main problems of the stator core cooling are identified also. The variant of heat transfer enhancement in the stator core is proposed. The variant bases on the cooling channels design, taking into account the air distribution and heat load in the bars. As a result, proposed design provides the maximal bars temperature decreasing on the 5oC and insulation lifetime As the bars have minimum lifetime in turbogenerator design, that is why given improvement makes better reliability of the design.
