Abstract
The invention relates to a falling film distributor component for an evaporator, in particular to a refrigerating fluid gravitational trickling plate for a falling film distributor. The refrigerating fluid gravitational trickling plate for the falling film distributor comprises a U-shaped tray and triangular holes which are uniformly and densely distributed in the U-shaped tray; triangular flow guide plates which are matched with the triangular holes are arranged under the triangular holes of the U-shaped tray; and flow guide wings which are recessed are arranged on two sides of the tip of each triangular flow guide plate. The refrigerating fluid gravitational trickling plate for the falling film distributor has the beneficial effects that under the effects of the triangular flow guide plates and the flow guide wings, refrigerating fluid can overcome a viscous force and flow downwards, a large liquid drop can be formed at the pointed bottom of the inverted triangle of each flow guide plate, under the effect of the gravity, the large liquid drops smoothly drop onto a heat exchange tube and wet the outer surface of the heat exchange tube so as to form a liquid film, and therefore, groundwork is laid for next film boiling.
Description
Technical field
The present invention relates to vaporizer falling film type dispenser part, refers specifically to a kind of falling film type allotter cold-producing medium gravity
Drop tray.
Background technology
The course of work of falling liquid film allotter is usually that the two phase refrigerant after throttling expansion is entered and is arranged on vaporizer
Top allotter, by multistage reallocation, two phase refrigerant is evenly arranged in allotter, last cold-producing medium by positioned at point
The water hole of orchestration bottommost is reserved, and is dropped on heat exchange pipe of evaporator, from top to bottom, is dripped successively, so as to reach uniform point
The effect matched somebody with somebody.In above process, the factor for affecting refrigeration most critical is evenly distributing for cold-producing medium, and the knot of allotter
Structure quality determines the quality of cold-producing medium distribution effects.In current industry, conventional common drop tray bottom typically arranges circle
Hole, square opening or opposite side shape hole, as the cold-producing medium in handpiece Water Chilling Units contains a small amount of lubricating oil, are provided with cold-producing medium certain
Viscosity, simple action of gravity can not overcome viscous force near completely and smoothly can not drop to downwards on heat exchanger tube, also just not
Energy complete wetting heat exchange pipe external surface, is unfavorable for that film boiling is conducted heat.Whether fountain allotter or dripping type allotter,
It is still not fully up to expectations that its distribution plate drop drenches effect, it is impossible to fully achieves effective cold-producing medium distribution, therefore, it is to ensure cold-producing medium
Evenly distribute and be smoothly dropped on heat exchanger tube, it is necessary to design a kind of reasonable and easy to process allotter drop and drench structure.
The content of the invention
For the deficiency in structure in prior art, the present invention provides a kind of falling film type allotter cold-producing medium gravity drop and drenches
Disk.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of falling film type allotter cold-producing medium gravity drop is drenched
Disk, including U-shaped pallet and the delthyrium being uniformly clouded on U-shaped pallet；
Delthyrium on the U-shaped pallet is arranged with the triangle flow deflector being adapted therewith；
The sophisticated both sides of the triangle flow deflector are provided with the flap for concaving.
The invention has the beneficial effects as follows：Liquid refrigerant can be overcome by the effect of flow deflector triangle and flap
Viscous force simultaneously flows downward, and forms big drop in the pointed bottom of flow deflector inverted triangle, and by the effect of gravity, is to make greatly
Drop is smoothly dropped on heat exchanger tube, moistening heat exchange pipe external surface, and then forms liquid film, is that paving is carried out in next step film boiling
Pad.
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, the U-shaped pallet surrounding is provided with end plate.
The invention has the beneficial effects as follows：It is difficult to overflow because liquid refrigerant is excessive,
Further, the delthyrium is once to be stamped to form with the triangle flow deflector being adapted.
The invention has the beneficial effects as follows：Larger drop can be formed in the initiating terminal of drippage, make liquid refrigerant more
Smooth drippage, it is easier to form larger liquid film in heat exchanger tube.

Fig. 3 is 2 schematic diagrams of present invention local；
Fig. 4 is delthyrium structural representation of the present invention；
Fig. 5 is flap structural representation of the present invention.
In the accompanying drawings, the list of designations represented by each label is as follows：1st, U-shaped pallet；2nd, delthyrium；3rd, triangle water conservancy diversion
Piece；4th, flap；5th, end plate；
Specific embodiment
The principle and feature of the present invention are described below in conjunction with accompanying drawing, example is served only for explaining the present invention, and
It is non-for limiting the scope of the present invention.
As shown in Fig. 1～5：Including U-shaped pallet 1 and the delthyrium being uniformly clouded on U-shaped pallet 12；
Delthyrium 2 on the U-shaped pallet 1 is arranged with the triangle flow deflector 3 being adapted therewith；The triangle flow deflector
3 sophisticated both sides are provided with the flap 4 for concaving.
1 surrounding of U-shaped pallet is provided with end plate 5.
The delthyrium 2 is once to be stamped to form with the triangle flow deflector 3 being adapted.
The present invention operation principle be：Under gravity, liquid refrigerant passes through delthyrium and leads along triangle
Flow is dripped, and converges into than larger drop at the tip of triangle flow deflector, continues to depart from triangle water conservancy diversion by the impact of gravity
Piece, drops on the heat exchanger tube immediately below triangle flow deflector, by the guide functions of triangle flow deflector, so as to avoid
The splashing of liquid refrigerant, it also avoid the adverse effect that the disorderly flowing of two phase refrigerant brings.
The foregoing is only presently preferred embodiments of the present invention, not to limit the present invention, all spirit in the present invention and
Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
