To (M+1) individual independent coolant liquid storage area is divided into, immediately below wherein M >=N, and each coolant shower, one is equipped with
The coolant distributing disc dividing plate.
In this utility model, described distributed falling film evaporator belongs to custom words, and which is meant that
Disk dividing plate is set up so that the form of the coolant distributing disc in falling film evaporator is changed into distributed set-up mode.That is, described system
Refrigerant distribution device is distributed falling liquid film allotter.
In this utility model, the coolant shower is used for for coolant being sprayed at coolant distributing disc, is allowed to equably spray
It is sprinkled upon on Guan Zhen, high-efficiency evaporating.The coolant shower is arranged in this utility model the top of the coolant distributing disc
Mode, compares that traditional " coolant shower is arranged in above coolant distributing disc, has needed a certain distance between the two, occupancy
Structure space is larger " structure for, compacter, practical.
It is preferred that the coolant distributing disc dividing plate is sheet metal component of the tuber according to the size design of coolant distributing disc；Described
Coolant distributing disc dividing plate is preferably welded on the coolant distributing disc.
It is preferred that the middle position between the adjacent coolant shower of each two be provided with coolant distributing disc described in every
Plate, i.e. M with the relation of N are：M=2N-1.
Positive effect of the present utility model is：Distributed falling film evaporator of the present utility model is applied to centrifugal
Cold water (heat pump) unit, can normally run in the case where machine room in-situ horizontal degree is not good, even if in constitution water Pingdu 5mm/m
Under the conditions of remain to normal work, the requirement ultimate value even for levelness can reach 8mm/m；Not only solve units' installation
The not good dry blowing for causing of levelness and performance degradation, and simple structure, it is adaptable to different size type.

Specific embodiment
This utility model is further illustrated below by the mode of embodiment, but therefore this utility model is not limited in
Among described scope of embodiments.
Embodiment 1
The structural representation of the distributed falling film evaporator of embodiment 1 is as shown in Fig. 1～5.The distributed falling film evaporation
The inside of device is provided with a refrigerant distributing device 1 in the horizontal direction, and the refrigerant distributing device 1 includes 4 coolant showers
103 and a coolant distributing disc 101, the coolant shower 103 is arranged in the top of the coolant distributing disc 101, and along described
The coolant distributing disc 101 is divided into 4 coolant sprinkling regions by the length direction of distributed falling film evaporator；The coolant point
The bottom of cloth disk 101 is additionally provided with 7 coolant distributing disc dividing plates 102, and those coolant distributing disc dividing plates 102 are by the coolant distributing disc
101 are divided into 8 independent coolant liquid storage areas along the length direction of the distributed falling film evaporator, and each coolant spray
The underface of shower pipe 103 is equipped with coolant distributing disc dividing plate 102 described in.
In the present embodiment, the coolant shower 103 is used for for coolant being sprayed at coolant distributing disc 101, is allowed to uniform
Be sprayed on Guan Zhen, high-efficiency evaporating.The coolant shower 103 is arranged in the coolant distributing disc 101 in the present embodiment
Top mode, compare traditional " coolant shower is arranged in above coolant distributing disc, need between the two certain away from
From the structure space of occupancy is larger " structure for, compacter, practical.

Effect example 1
When contrast experiment is carried out：The structure of traditional falling film evaporator, when levelness is not good, two ends drop reaches
During 41.75mm, the falling liquid film allotter in traditional falling film evaporator has occurred aneroid region, and this part cannot realize uniform point
Liquid, heat exchanger tube occur dry blowing phenomenon, reduce heat exchange property, and unit can now occur performance degradation problem.
And the distributed falling film evaporator described in embodiment 1, by installing additional for coolant distributing disc dividing plate, by coolant distributing disc
An original large-scale liquid storage is distinguished into 8 small-sized coolant liquid storage areas, and this design will reduce levelness temperature to each small-sized storage
The impact of liquid zone liquid level.When this distributed falling liquid film allotter runs into levelness not good situation, two ends drop reaches 41.75mm
When, there is liquid level tilt problem in each small-sized liquid storage area, but as liquid storage area is divided into 8 by 1, influence value is greatly reduced, respectively
There is not aneroid region in small-sized liquid storage area, illustrate this distributed falling liquid film distributor can when levelness is not good normal work.
Generally speaking, the distributed falling film evaporator that this utility model is provided is applied to centrifugal cold water (heat pump) unit,
Can normally run in the case where machine room in-situ horizontal degree is not good, it is to avoid unit in the case where levelness is not good, send out by vaporizer
Raw dry blowing phenomenon, affects heat exchange property, and the decay and failure for causing unit overall performance occurs.Even if in constitution water Pingdu 5mm/
Normal work is remained under conditions of m, and the requirement ultimate value even for levelness can reach 8mm/m, compare traditional falling film type
Vaporizer for rigors of the levelness within 1mm/m, the work of distributed falling film evaporator of the present utility model
Condition much more relaxed, its requirement for horizontality are only 1/5th of traditional falling film evaporator, even lower, for site operation will
Ask low, meet various harsh Practical Conditions both at home and abroad and limit.
