HEAT EXCHANGER USING FLASH EVAPORATION AND STEAM GENERATOR HAVING THE SAME

摘要

The present invention relates to a heat exchanger using instantaneous evaporation, comprising: a first heating flow path which is changed into a saturated liquid by single-phase heat exchange while passing a heated liquid through which heat is transferred from the heat transfer medium; An evaporation flow path that instantly changes state to a saturated gas by instantaneous evaporation due to a pressure drop while passing a saturated liquid through which heat is transferred from the medium and a saturated gas which communicates with the instantaneous evaporation flow passage and receives heat from the heat transfer medium, And a second plate having a first plate having a second heating channel heated and discharged by heat exchange and a second plate provided on a lower side or a lower side of the first plate and having a heat transfer medium passage through which the heat transfer medium passes .
