Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To increase the heat exchange rate as the whole heat exchanger, and to improve an evaporator so as to promote the miniaturization and efficiency of a machine, by arranging the pipelines with the lowest heat transfer coefficient, or the lowest pipeline and the second lowest pipeline in the heat transfer coefficient in such a manner that they do not overlap by being divided into the front and rear tiers in the first direction. SOLUTION: A refrigerant flows in from the refrigerant entrances 50a and 51a of each pipeline 1, and it flows out from the exits 51b and 50b of each pipeline 5. The pipeline having the highest heat transfer coefficient 5 among the pipelines and the lowest pipeline or the second lowest pipeline 6 in the heat transfer coefficient are arranged in such a manner that they are divided into the front and rear tiers in the direction of air 60 to overlap each other. Thereby, the air which passes through the pipelines 5 and 6 has already passed through the pipeline having the highest heat transfer coefficient 6 in spite of passing through the pipeline having the lowest heat transfer coefficient 6, so that the lowering in heat of in the heat exchange is relaxed, and that the heat exchange rate as the whole exchanger is increased.  As a result of that, an evaporator can be miniaturized, and the miniaturization of a machine can be promoted.
