<P>PROBLEM TO BE SOLVED: To provide a heat exchanger capable of inhibiting the impairing of a heat transferring characteristic in a heat exchanging part even when the viscoelastic surface active agent aqueous solution is used as a heat transfer medium. <P>SOLUTION: This heat exchanger exchanges the heat with the other heat transfer medium at the heat exchanging part by using the surface active agent aqueous solution as the heat transfer medium. A plurality of pairs of disc elements 30, 32 are stacked at an upstream end part of a heat transfer pipe 24 of the heat exchanging part along the heat transfer medium flowing direction. The pair of disc elements 30, 32 are provided with one or more holes 36, 38 regulating flow channel holes, and the surface active agent aqueous solution loses its viscoelasticity, when it flows through the holes 36, 38 of the disc elements 30, 32, whereby the impairing of the heat transferring performance can be prevented. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
