Top in shell 10, and it is corresponding with inlet 21.When in use, liquid distributor 40 is used for the equal liquid of refrigerant is carried out, will be cold
Matchmaker more uniformly drops onto set of heat exchange tubes, and set of heat exchange tubes is allowed to carry out more uniform heat exchange.
More preferably, in the technical scheme of this embodiment, as shown in Figure 1, evaporator further includes overheat set of heat exchange tubes
50, the lower part in shell 10 is arranged in overheat set of heat exchange tubes 50, and is located at the lower section of the second set of heat exchange tubes 32.It is used in evaporator
During, the refrigerant not gasified by set of heat exchange tubes can accumulate in the lower part of shell 10, the overheat of lower part in shell 10
Just refrigerant exchanges heat set of heat exchange tubes 50 with the part, and the part refrigerant is allowed also to be evaporated to gaseous coolant.
As shown in Figure 1, as a preferred embodiment, evaporator further includes that the first drying tube group 61 and second is dry
Pipe group 62, the first drying tube group 61 and the second drying tube group 62 are respectively distributed to the two sides in shell 10.By dry by first
Pipe group 61 and the second drying tube group 62 are separately positioned on the two sides in shell 10, can increase airflow channel dried together
Journey allows refrigerant more fully to gasify.
Optionally, set of heat exchange tubes is between the first drying tube group 61 and the second drying tube group 62.So, so that it may
Space carries out the arrangement of heat exchanger tube in reasonable utilization shell 10.
As shown in Fig. 2, optional, adjacent four heat exchanger tubes of set of heat exchange tubes are laid out in distributed rectangular or parallelogram point
Cloth layout, distribution form are not limited to the kind in figure, other distribution forms are also feasible.Likewise, overheat set of heat exchange tubes 50,
Adjacent four heat exchanger tubes of first drying tube group 61 and the second drying tube group 62 are laid out in distributed rectangular or parallelogram distribution
Layout, distribution form are not limited to the kind in figure, other distribution forms are also feasible.
It should be noted that above-mentioned vaporizer technology scheme is particularly suitable for downward film evaporator.First set of heat exchange tubes
31, the second set of heat exchange tubes 32, third set of heat exchange tubes 33 and overheat set of heat exchange tubes 50 can be the identical large-scale heat exchanger tube of diameter,
Or the large-scale heat exchanger tube that diameter is different.First drying tube group 61 and the second drying tube group 62 can be identical small for diameter
Type heat exchanger tube, or the different small-sized heat exchanger tube of diameter.
Specifically, if the first set of heat exchange tubes 31 is 100% falling film type evaporation pipe, then the second heat exchange according to heat exchange efficiency
Pipe group 32 and third set of heat exchange tubes 33 are respectively 80% falling film type evaporation pipe and 50% falling film type evaporation pipe.In technology of the invention
In scheme, it has been merely given as simple layout, when applying to production, has needed to assess unit service condition and requirement capability, fits
When adjustment falling film type evaporation pipe it is functional strong and weak.
