PROBLEM TO BE SOLVED: To supply a tube with uniform gas/liquid refrigerant by making at least one opening such that the openings of two adjacent regulating plates are not aligned. SOLUTION: Holes 12a, 12b in regulating plates 11a, 11b being inserted into a heat exchanger are shifted from each other so that refrigerant liquid does not flow through and the regulating plates 11a, 11b are inserted alternately into a rear tank 8 along the refrigerant channel while varying the opening rate depending on the internal refrigerant channel resistance. With such an arrangement, even when refrigerant liquid and gas flow under uneven state, the refrigerant liquid and gas are mixed by means of the regulating plate 11a to produce refrigerant passing through the hole 12a of the regulating plate 11a and refrigerant striking the regulating plate 11a to flow into a plurality of tubes 4 in front of the regulating plate 11a. Liquid refrigerant having high dynamic pressure passing directly through the hole 12a are brought into collision, along with refrigerant gas, against the regulating plate 11b having a shifted opening and mixed to supply the tube 4 with gas/liquid uniform refrigerant thus enhancing performance of the heat exchanger.
