Through the research on heat exchange capacity, it is found that the evaporator has undergone significant technological changes. Currently, shell and tube heat exchangers have dry evaporators, full liquid evaporators, and falling film evaporators. From the perspective of the future, The development of the falling film evaporator is considerable, and it is developing rapidly in the industry.
但降膜式蒸发器仍存在着很多技术瓶颈,在换热能力上还具有很大的挖掘潜力。现有的布液器结构已经各式各样,结构也基本成熟。但是仅仅靠针对布液器结构的设计只能保证换热器上部区域换热均匀性,无法覆盖到整体换热区域。因此,降膜式蒸发器的换热结构设计还是有待于提高。However, there are still many technical bottlenecks in the falling film evaporator, and there is still great potential in the heat exchange capacity. The existing liquid dispenser structures have various structures and the structure is basically mature. However, the design of the liquid distributor structure alone can only guarantee the heat exchange uniformity in the upper area of the heat exchanger, and cannot cover the entire heat exchange area. Therefore, the design of the heat transfer structure of the falling film evaporator still needs to be improved.

经过发现,当液态冷媒通过进液口21进入壳体10后,会被布液器30较为均匀分布到换热管组上。随着液态冷媒在换热管组上被不断蒸发。受气态冷媒的影响,液态冷媒的分布均匀性会变差,进而导致换热均匀性变差。It has been found that when the liquid refrigerant enters the casing 10 through the liquid inlet 21, it will be evenly distributed on the heat exchange tube group by the liquid distributor 30. As the liquid refrigerant is continuously evaporated on the heat exchange tube group. Affected by the gaseous refrigerant, the uniformity of the distribution of the liquid refrigerant will be worse, which will lead to the worsening of the heat transfer uniformity.

The evaporator includes a casing 10, a liquid inlet 21 and an air outlet 22, and the liquid inlet 21 and the air outlet 22 are disposed on the casing 10. The evaporator further includes a liquid distributor 30, a first heat exchange tube group 41, a second heat exchange tube group 42 and a first liquid equalization tube group 51. The liquid distributor 30 is disposed on the upper portion of the casing 10 and communicates with the liquid inlet. Corresponding to the port 21, the liquid distributor 30 is used to disperse the refrigerant passed through the liquid inlet 21. The first heat exchange tube group 41 and the second heat exchange tube group 42 are disposed in the casing 10, and the second heat exchange tube group 42 is located below the liquid distributor 30. The first homogenizing tube group 51 is disposed in the casing 10 and is located between the first heat exchanging tube group 41 and the second heat exchanging tube group 42.

应用本公开的技术方案,当冷媒流经第一换热管组41后,冷媒会落在第一均液管组51上。由于第一均液管组51的换热管管径小,且分布密度大,当冷媒流经第一均液管组51时,就会被第一均液管组51的换热管随机分配地更加均匀,使得冷媒可以被再次均液,冷媒就可以均匀地落在第二换热管组42上进行换热。这样一来,就提高了蒸发器的换热均匀性,提高整体换热效率。Applying the technical solution of the present disclosure, after the refrigerant flows through the first heat exchange tube group 41, the refrigerant will fall on the first homogenizing tube group 51. Due to the small diameter and large distribution density of the heat exchange tubes of the first homogenizing tube group 51, when the refrigerant flows through the first homogenizing tube group 51, it will be randomly distributed by the heat exchange tubes of the first homogenizing tube group 51. The ground is more uniform, so that the refrigerant can be homogenized again, and the refrigerant can evenly fall on the second heat exchange tube group 42 for heat exchange.
