<p><P>PROBLEM TO BE SOLVED: To supply a refrigerant in a gas-liquid two-phase state evenly to respective refrigerant flow paths of a laminated heat exchanger via a plurality of first refrigerant ejection holes 15 of a pipe 14, and to prevent at that moment the refrigerant from flowing in the laminating direction through a hole edge of a communication hole therefor. <P>SOLUTION: The diameter D1 of a first hole 6 of a first frame 7 is made larger than the diameter D2 of a first communication hole 1 of a plate 4. Thereby, a labyrinth space 16 is formed between the first communication hole 1 of the pair of adjacent plates 3 and the plate 4 and the first hole 6 of the first frame 7, and by existence of the labyrinth space 16, the refrigerant is prevented from flowing in the axial direction of the pipe 14. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
