ことは難しく片寄った分配しかできなかった。Conventionally, well-known laminated heat exchangers are manufactured by stacking two flat core units and stacking them alternately with fins in several stages, and this laminated heat exchanger is used as an evaporator. The refrigerant condensed and liquefied in the 75k condenser is depressurized and expanded by the expansion valve before entering the evaporator, and enters the evaporator, which has multiple evaporation sections, in a gas-liquid mixed state.
If the refrigerant is arranged horizontally, it is difficult to distribute the refrigerant uniformly to the many evaporation sections, and only uneven distribution is possible.
そのため縦型配置しか使用できず、設置場所の制約をう
ける自動車用の冷房装置の蒸発器として使用することは
困難であった。Therefore, only a vertical arrangement can be used, making it difficult to use it as an evaporator for an automobile cooling system, which is subject to restrictions on installation location.

蒸発器が十分な性能を発揮できなかった。In addition, especially in automotive cooling systems, the compressor capacity fluctuates with changes in vehicle speed and the cooling load fluctuates significantly, so the refrigerant flow rate fluctuates significantly, so even if the system is installed vertically, it is difficult to ensure uniform refrigerant distribution. It makes it difficult to
The evaporator was not able to perform adequately.

The high-pressure liquid that has been condensed and liquefied in a condenser enters the 11 evaporator, and is evaporated under reduced pressure through fixed throttles for each of the multiple evaporation sections installed inside the evaporator. The purpose of the present invention is to provide a versatile stacked evaporator with uniform distribution of refrigerant within the evaporator, good performance, and unlimited installation conditions at a low cost.
