Stacked heat exchanger and method of manufacturing the same |
摘要 |
The present invention discloses a stacked heat exchanger in which separate flow paths 54 and 55 which are formed by corrugated inner fins 52 and 53 are disposed in chambers 48 and 49 of a flat tube 41, and also separate U-shaped flow paths 56 are formed at the U-turn portion 50 to make the flow of refrigerant smooth, increase the area of flow paths, and eliminate the stagnation of refrigerant at the U-turn portion 50. The separation of refrigerant into two phases of gas and liquid due to centrifugal forces at the U-turn portion 50 is limited to the inside of each divided U-shaped flow path 56, thereby the distribution of the gas and liquid phases can be decreased. Also disclosed is a method of manufacturing a stacked heat exchanger, in which the reliability of flat tube 41 is improved, and the leakage of refrigerant is prevented.
