Kind Code:
A
Abstract:
To exchange heat between a heating-objective fluid and a heating medium with an intermediate medium interposed therebetween, in a lamination-type heat exchanger.SOLUTION: A lamination-type heat exchanger 12 comprises: a low-temperature layer 37 in which a low-temperature flow passage 37a into which a heating-objective fluid is introduced is formed; a first high-temperature layer 38 which is laminated while adjoining the low-temperature layer 37, and has a first high-temperature flow passage 38a into which an intermediate medium is introduced; and a second high-temperature layer 39 which is laminated while adjoining the first high-temperature layer 38, and has a second high-temperature flow passage 39a into which a heating medium is introduced. The intermediate medium is composed of an alcohol having a solidification point whose temperature is -80°C or lower at which a liquid state can be maintained even if heat is exchanged between the heating-objective fluid and the heating medium in the first high-temperature flow passage 38a, or an alcohol aqueous solution.SELECTED DRAWING: Figure 3
