Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2020/045662
Kind Code:
A1
Abstract:
Provided is a heat exchanger wherein a heat exchange unit formed by assembling plates is arranged with a suitable orientation inside a shell, a heat exchange between a gas-phase high-temperature fluid and a liquid-phase low-temperature fluid is carried out reliably, and evaporation of the low-temperature fluid and condensation of the high-temperature fluid can be made to proceed in parallel efficiently. This heat exchanger 10, which carries out a heat exchange between water vapor and a steam-power-cycle working fluid and serves as both a condenser for condensing water vapor and an evaporator for evaporating a working fluid, has a configuration wherein a heat exchange unit 11, in which a plurality of heat exchange plates have been integrated side by side, is arranged inside a shell 12, thereby alternately producing, between the heat exchange plates arranged side by side, flow passages through which the water vapor flows and flow passages through which the working fluid flows. The working fluid is evaporated and the water vapor is condensed by making the water vapor and working fluid flow through the respective flow passages such that the flows thereof are orthogonal to each other. Thus, the size of the heat exchange unit 11 can be reduced while enabling a heat exchange to be carried out via the heat exchange plates, and the overall size of a system containing the heat exchanger 10 can be reduced.
