Title:
EVAPORATOR AND RANKINE CYCLE SYSTEM
Document Type and Number:
Japanese Patent JP2017032232
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a new technology for heating working fluid to a higher temperature while preventing the working fluid from being excessively heated in an evaporator.SOLUTION: An evaporator (10) includes: a heat source gas introduction section (12) for introducing heat source gas from heat source gas piping (11); a heat source gas flow passage (22) in which the heat source gas introduced from the heat source gas introduction section (12) flows; a working fluid heating section (15) disposed on the heat source gas flow passage (22) to heat the working fluid by using the heat source gas; a flow passage cross section expansion section (13) for gradually expanding a cross section of the heat source gas flow passage (22) from the upstream side to the downstream side of the heat source gas flow passage (22); and a heat source gas flow straightening plate (14) that is disposed on the heat source gas flow passage (22) on the upstream side of the working fluid heating section (25) and has a plurality of through holes (14h) allowing passage of the heat source gas to straighten the flow of the heat source gas.SELECTED DRAWING: Figure 2
