Abstract

PROBLEM TO BE SOLVED: To uniformalize the dispersion of refrigerant liquid and to improve performance by a method wherein a narrow mixing space is formed between a refrigerant inlet nozzle hole and a refrigerant passage, and after mixing of gas and liquid in the mixing space, the mixture is caused to flow in the refrigerant passage. SOLUTION: Mixing spaces 7 are annular comparatively narrow space and communicate with each other effected through a small hole 9 formed through a heat transfer plate 1. The outer peripheral edge of the mixing space 7 communicates with a refrigerant passage R through an annular narrow gap 8 extending throughout a whole periphery, and refrigerant liquid entering a refrigerant inlet nozzle 5 first enters the refrigerant inlet nozzle hole 5A and advances in the mixing space 7 through the gap 5b of the opening 5a part of the adjoining heat transfer plates 1. Since the sectional area of a small hole 9 is set to greater than the section area of the annular gap 8, air bubbles and liquid are mixed together in the whole mixing space. Thus air bubbles are made small and simultaneously uniformly dispersed in the liquid.
