<p>PROBLEM TO BE SOLVED: To uniformize the temperature distribution of a regenerative medium, by preventing the deviation of a gas/liquid two phase refrigerant. SOLUTION: In this heat exchanger, a heat transfer plate having openings at four corner parts thereof is provided with a groove surface and a smooth surface 40 mutually extending in the longitudinal direction thereof. A protruded part 41 is so arranged above a first opening as a refrigerant inflow path 61a to be inclined toward an inlet part 40a of the smooth surface 40 from the refrigerant inflow path 61a. The smooth surface 40 is composed of a gas path, and the protruded part 41 is composed of an introduction means by which a gas/ liquid double phase refrigerant flowing in from the refrigerant inflow path 61a is separated into a gas and a liquid to introduce a gas refrigerant RG to the gas path.</p> |
