Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, but not as to this practicality
New restriction.
Utility model people has found during numerically modeling is carried out to centrifuge evaporator of the prior art, to evaporator
Internal baffle plate structure is optimized can be in the case of ensureing that crushing is not increased, in further reduction cold media gas
Liquid content.Therefore, mainly consider at 3 points in the design of liquid barrier in the utility model：Filter effect, liquid level surface pressing
The uniformity and total crushing, and find on this 3 points an equalization point.
Refer to the liquid barrier of the evaporator in Fig. 5 to Figure 14, the utility model includes plate body, wherein, the shape on plate body
Into have it is one or more be used for increase the plate body surface area and water conservancy diversion grooves 1.For example, in a preferred embodiment,
The section of groove 1 in the utility model can also use the section of other shapes, as long as can certainly with V-shaped or arc
Reach above-mentioned purpose.It is highly preferred that be formed with multiple grooves 1 be arrangeding in parallel on plate body, these grooves 1 are along plate body
Axis direction extends the length range of whole plate body.
Because the utility model adds groove 1 on the plate body of liquid barrier, thus can ensure overall dimensions it is constant and
In the case of not increasing unit crushing, increase the surface area of liquid barrier, to filter droplet to greatest extent, so as to further change
The influence that kind absorbing gas belt liquid is brought.
During work, the gas from vapor-liquid separation device assembly 5 out still contains some drop, and this partial drop is in gas
Because the effect of inertia can be impacted on liquid barrier 2 and other walls in steering procedure, liquid barrier 2 can make again to lead to after gas turns
Outlet tube assembly 4 is crossed, so as to play a part of filtering.
In the process, every one of groove 1 in the utility model can play the guide functions of drop, the groove with along with
Droplet flow resistance in 1 is small, and drop is gathered together, and makes drop larger, its be raised air-flow entrainment probability relatively also compared with
It is small, drop can be made to drip (the arrow in such as Fig. 7 and Figure 11 after single fixed-direction flocks together, then with gravity direction
It is shown), reduce by the probability of reentrainment in drop dropping process, therefore improve filter effect, it is ensured that unit crushing
In the case of not increased, infringement of the absorbing gas belt liquid to compressor is reduced, compression efficiency is improved.
It is highly preferred that the groove 1 in the utility model is formed in the upper surface of plate body, and groove 1 is by the lower surface of plate body
It is outstanding, so, the surface area of both sides above and below plate body can be increased simultaneously.Obviously, groove is only formed on an upper, and following table
Face is the form of shiny surface, falls within protection domain of the present utility model.
Preferably, the first end of plate body is open architecture or enclosed construction, and the second end (i.e. outlet end) of plate body is to open
Put structure.During installation, the first end of plate body, can when its end plate contact with housing 3 towards one end of the housing 3 of evaporator
To use open architecture, and when there is an intersegmental gap as shown in figs. 5 and 9 between its also housing 3, then it can use closed
Structure.Preferably, groove 1 extends to the second end by the first end of plate body, through the whole length scope of plate body.
The cross sectional shape of plate body in the utility model can be diversified, for example, in the reality shown in Fig. 5 to Fig. 8
Apply in example, the section of plate body is in circular arc generally；In the embodiment shown in Fig. 9 to Figure 12, the section of plate body takes the shape of the letter U,
Wherein, the bottom of the U-shaped is horizontal, and both sides are skewed in what is expanded outwardly.
Further, when Figure 13 and Figure 14 respectively illustrate arc and U-shaped section, the utility model with it is of the prior art
Surface area ratio between plate body is relatively schemed.In Figure 13 and Figure 14, shown in dotted line is the shape of plate body of the prior art, solid line
Shown is the shape of the plate body in the utility model, can be clearly observed from figure, at the position in region 7, surface
Product is significantly increased, therefore increases circulation area, so as to also reduce crushing to a certain extent, further, is increased
Big circulation area size depends on groove type and number.
Because the utility model improves absorbing gas belt liquid phenomenon, therefore alleviate " liquid hammer " is produced to blade, slow down pair
The corrosion of blade, so as to avoid potential safety hazard.
Fig. 5, Fig. 6, Fig. 9 and Figure 10 are refer to, the utility model additionally provides a kind of evaporator, including above-mentioned liquid barrier
2.In this embodiment, evaporator includes housing 3, and liquid barrier 2 is preferably pacified with being slightly slanted with the axis of relatively described housing 3
The lower section of outlet tube assembly 4 in housing 3 and positioned at housing 3, so, every one of groove structure of liquid barrier can rise
To guide functions, allow drop to be flocked together along incline direction, be more easy to drip with gravity direction, and make droplet size larger,
The probability that it rolls up suction entrainment in by liquid barrier dropping process by refrigerant air-flow is lower.It is highly preferred that liquid barrier 2 and the shell
Included angle A between the axis of body 3 is less than or equal to 5 degree.
Preferably, the first end of liquid barrier 2 is abutted or separated with the end plate of housing 3.
Preferably, evaporator also includes vapor-liquid separation device assembly 5, is arranged on the lower section of liquid barrier 2.
The utility model additionally provides a kind of refrigerating plant, including above-mentioned evaporator.Due to the steaming in the utility model
Groove structure is employed on the liquid barrier 2 for sending out device and is obliquely set, therefore the drop in flooded evaporator can be made easily to assemble,
Easily drippage, can further improve the absorbing gas belt liquid measure of unit in the case of ensureing that crushing is not increased.
Certainly, above is preferred embodiment of the present utility model.It should be pointed out that for the ordinary skill of the art
For personnel, on the premise of the utility model general principle is not departed from, some improvements and modifications can also be made, these improvement
Protection domain of the present utility model is also considered as with retouching.
