<P>PROBLEM TO BE SOLVED: To provide a heat exchanger of exhibiting stable performance. <P>SOLUTION: An integrated unit 20 is integrally assembled of: a windward side first evaporator 15 connected to an outlet side of an ejector 14; a leeward side second evaporator 18 connected to a refrigerant suction port of the ejector 14; a contraction mechanism 17 arranged on a refrigerant inlet side of the second evaporator 18 and for decompressing a refrigerant flow; and a refrigerant constitutive member 80, and has one refrigerant inlet 25 and one refrigerant outlet 26. The refrigerant constitutive member 80 is provided with: an outer plate 81; an inner plate 82; a distribution block 83; a connecting block 84; and a closing member 63. The outer plate 81 is combined with the inner plate 82, to constitute an inflow passage 23. The distribution block 83 provided with: a main opening part 83b for supplying a refrigerant to the ejector 14; and a branch opening part 83c for supplying the refrigerant to the contraction mechanism 17. Each of the opening parts 83b, 83c has a circular-shaped opening edge in the shortest distance T from an inner face of the inflow passage 23. <P>COPYRIGHT: (C)2010,JPO&INPIT |
