Abstract
A stacked heat exchanger has a high temperature layer with a number of channels into which a high temperature-side fluid is introduced; and a low temperature layer superposed on the high temperature layer having a number of channels into which a low temperature-side fluid is introduced at a temperature lower than the temperature of the high temperature-side fluid. Each channel 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 flowing 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 flowing within the high temperature layer. The upstream-side parts of the low temperature layer occupy a total area smaller than a total area of the downstream-side parts of the low temperature layer.
