Title:

STACKED HEAT EXCHANGER

Document Type and Number:

WIPO Patent Application WO/2019/235211

Kind Code:

A1

Abstract:

This stacked heat exchanger is provided with: a high temperature layer that comprises a plurality of channels into which a high temperature-side fluid is introduced; and a low temperature layer that is superposed on the high temperature layer and comprises a plurality of channels into which a low temperature-side fluid is introduced, said low temperature-side fluid being at a temperature that is lower than the temperature of the high temperature-side fluid. Each one of the plurality of channels of the low temperature layer has: an upstream-side part in which at least some of the low temperature-side fluid evaporates by being heated by the high temperature-side fluid that flows within the high temperature layer; and a downstream-side part in which the low temperature-side fluid that has evaporated in the upstream-side part is heated by the high temperature-side fluid that flows within the high temperature layer. The ratio of the areas of the plurality of upstream-side parts in a predetermined area of the low temperature layer is lower than the ratio of the areas of the plurality of downstream-side parts in the predetermined area of the low temperature layer.
