Abstract：

Utilizing　reliable　and　hermetic　expander　with　internal　generator　is　an　important　development　direction　of　organic　Rankine　cycle　(ORC).　It　is　simple　and　feasible　to　use　the　expander　exhaust　to　cool　the　generator　in　hermetic　expander.　However,　the　exhaust　temperature　of　the　expander　in　ORC　system　is　relatively　high,　and　the　cooling　effect　on　the　generator　needs　to　be　studied　specifically.　In　this　paper,　an　equivalent　thermal　circuit　model　of　the　generator　was　established　based　on　the　lumped　parameter　concept.　The　variations　of　the　highest　temperature　and　temperature　rise　of　the　stator　winding　under　different　working　conditions　were　revealed.　Results　show　that　the　highest　temperature　and　temperature　rise　of　the　generator　increase　with　the　improvement　of　evaporation　temperature,　reaching　151°　and　85°,　respectively.　The　highest　temperature　and　temperature　rise　of　the　generator　decrease　with　the　increase　of　condensation　temperature.　If　the　condensation　temperature　is　set　to　be　30°,　the　maximum　temperature　and　temperature　rise　can　reach　126°　and　65°,　respectively.　©　2023　Beijing　University　of　Technology.　All　rights　reserved.
