Abstract

PURPOSE: To obtain a high-performance heat exchanger by a method wherein small diametral heat transfer tubes are arranged in the front half on the inlet side of medium flowing through the heat transfer tubes while large diametral heat transfer tubes are arranged in the rear half on the outlet side of the medium flowing through the same.
CONSTITUTION: A vessel for fluid, which flows the outside of heat transfer tubes 1, 2, is formed of a tube plate 5, partitioning plates 3, heat transfer tubes 1, 2, penetrating through and fixed to the tube plate 5 and the partitioning plates 3, and a cylinder plate 4, enclosing these plates and tubes, while a heat exchanger is formed by attaching a lid plate 6, forming the passage of refrigerant in the heat transfer tubes on the tube plate 5. In this case, the heat transfer tubes 1 are provided with a small diameter and the heat transfer tubes 2 are provided with a large diameter. The refrigerant in the heat transfer tubes enters through an inlet port 7 in mixed gas and liquid condition, then, flows through the heat transfer tubes sequentially from the heat transfer tubes 1 to the heat transfer tubes 2 while effecting heat exchange between the fluid outside of the heat transfer tubes and becoming gaseous state, then, is discharged out of an outlet port 8. On the other hand, fluid outside of the heat transfer tubes enters from an entrance port 9 while effecting heat exchange between the refrigerant in the heat transfer tubes and meandering through a passage formed by the partitioning plates 3, then, is discharged out of another outlet port 10.
