Between the side plate of side.
As a further improvement on the present invention：It is this section of corresponding outlet open area that the total circulation area of fluid apertures is fallen in every section
1/10th, it falls fluid apertures and is evenly distributed with along evaporator length direction, adjacent spacing is 0.3 to 0.5m.
As a further improvement on the present invention：The inlet channel includes equal stomata and return-air hole, the return-air hole setting
In the upper region at a distance from this section of gas outlet less than 1.5 times of gas outlet diameters along its length, the air inlet except the region
Channel is equal stomata.
As a further improvement on the present invention：The gross area in every section of inner return-air hole and this section of gas outlet area equation.
As a further improvement on the present invention：The equal stomata is the bar-shaped trough being opened at the top of side plate.
As a further improvement on the present invention：The width of each bar-shaped trough is equal, the bar shaped remoter apart from gas outlet in every section
Groove depth is deeper.
As a further improvement on the present invention：Every section of the total circulation area of equal stomata is the 2 to 3 of this section of outlet open area
Times.
Compared with the existing technology, the present invention has the positive effect that：（1）The present invention is by setting inlet channel optimization
Meter can effectively control the flow velocity that the mixed working fluid in evaporator except gas averaging board rises and be protected on evaporator length direction
It holds uniformly, avoids local velocity is excessively high from causing gas-liquid separation effect poor, and then absorbing gas belt liquid phenomenon occur；（2）It can not in gas
Big drop will be aggregated by filler plate to detach, realize the promotion of separating effect by the droplet of Gravity Separation；（3）Bar shaped
Slot structure is simple, easy to process, more direct to the control of air inlet area.
Description of the drawings
Fig. 1 is the dimensional structure diagram of the present invention.
Fig. 2 is the dimensional structure diagram of the present invention, in figure serial number 7 it is signified be gas outlet projected position.
Specific implementation mode
The technical solution that the invention will now be described in detail with reference to the accompanying drawings：
Such as Fig. 1 and 2, a kind of flooded evaporator gas averaging board is arranged along evaporator length direction, for spiral-lock in the evaporation
The top of device inner cavity, the evaporator are divided into several sections along its length, and every section of center of top is provided with a gas outlet 7.
The gas averaging board includes bottom plate 1 and the side plate 2 positioned at 1 left and right sides of bottom plate, length of the bottom plate 1 along evaporator
Direction is horizontally disposed, and the side plate 2 of both sides tilts outward from bottom to top, the side edge of 2 lower end of side plate and 1 respective side of bottom plate,
Upper end with evaporator top inner wall for connecting；
Inlet channel is offered on the side plate 2, is symmetrical arranged positioned at the inlet channel of 7 both sides of gas outlet in every section, and away from
It is smaller to separate out the closer inlet channel area of gas port 7.Due to higher more being proximate to 7 pressure of inspiration(Pi) of gas outlet, flow velocity, by will be into
Gas channel is as above arranged, and can effectively control the flow velocity that the mixed working fluid in evaporator except gas averaging board rises and steam
It sends out and keeps uniform on device length direction, avoid local velocity is excessively high from causing gas-liquid separation effect poor, and then it is existing absorbing gas belt liquid occur
As.
It is offered on the bottom plate 1 and falls fluid apertures 6, the drop that aperture is only capable of meeting aggregation is fallen, and it is short cannot to form air-breathing
Road.Preferably, 1/10th that 6 total circulation area of fluid apertures is this section of 7 area of corresponding gas outlet are fallen in every section, fall 6 edge of fluid apertures
Evaporator length direction is uniformly distributed, and adjacent spacing is 0.3 to 0.5m.
Further to promote separating effect, wire mesh packing plate 3 is further respectively had in 1 left and right sides of bottom plate, it is described to fill out
The side edge of 3 lower end of flitch and 1 respective side of bottom plate, upper end with evaporator top inner wall for connecting；The filler plate 3 is located at
Between both sides side plate 2.It can not lean on the droplet of Gravity Separation that will aggregate into big drop by filler in gas to detach, realize
The promotion of separating effect.
For convenience of processing, separating effect is advanced optimized, it is ensured that the uniformity of air-breathing, the inlet channel is by following preferred
Design scheme is processed：
Inlet channel includes equal stomata and return-air hole 5, and the return-air hole 5 is arranged upper along its length and this section of gas outlet 7
Distance is less than in the region of 1.5 times of 7 diameters of gas outlet, and the inlet channel except the region is equal stomata.
The unilateral corresponding equal stomata in gas outlet 7, apart from no more than 1m, if exceeding 1m, should increase gas returning port away from gas outlet 7
Quantity.
The unilateral corresponding equal stomata in gas outlet 7, apart from no more than 1m, if exceeding 1m, should increase gas returning port away from gas outlet 7
Quantity.
Preferably, the equal stomata is the bar-shaped trough 4 for being opened in 2 top of side plate.The width of each bar-shaped trough 4 is equal, equidistantly
It is arranged, bar-shaped trough 4 depth remoter apart from gas outlet 7 is deeper in every section, has simple in structure, easy to process, air inlet area control
Make direct advantage.
Further, every section of the total circulation area of equal stomata is 2 to 3 times of this section of 7 area of gas outlet.
Preferably, the gross area in every section of inner return-air hole 5 and this section of 7 area equation of gas outlet.Side as a further preference
Case, 5 specification of return-air hole are identical as fluid apertures 6 is fallen.
