Embodiment
The present invention is elaborated below in conjunction with the accompanying drawings.
Fig. 1 shows a kind of situation of the installation site of end socket involved in the present invention.As shown in figure 1, end socket 1 is arranged on
On the feeder connection 21 of heat-exchanger rig 2.Feeder connection 21 is located at the upside of heat-exchanger rig 2.
Fig. 2 shows a kind of embodiment of end socket involved in the present invention.As shown in Fig. 2 end socket 1 includes gas-liquid
Distribution member 3 and end socket housing 11.Gas-liquid distribution member 3 is arranged in end socket housing 11, including gas-liquid distributor chamber 31 and entrance
Mozzle 32.The vertical section of gas-liquid distributor chamber 31 is trapezoidal in specular.Trapezoidal dividing plate 33 constitute the trapezoidal top and
Side；Plane clapboard 34 constitutes that this is trapezoidal following, i.e., gas-liquid distributor chamber 31 is enclosed by trapezoidal dividing plate 33 and plane clapboard 34
Form.Trapezoidal dividing plate 33 passes through welded seal with the joint of plane clapboard 34.The top of gas-liquid distributor chamber 31 is provided with upper shed
311, bottom is provided with multiple under sheds 312.The entrance point 321 of inlet honeycomb duct 32 exposes end socket housing 11, and the port of export 322 is worn
Upper shed 311 is crossed to stretch into gas-liquid distributor chamber 31.Under shed 312 be in downward funnel-form, and its position not with the port of export 322
Underface is overlapping.
The edge of plane clapboard 34 and the welded seal of end socket housing 11 so that end socket 1 is separated into by gas-liquid distributor chamber 31
Half section 12 and lower semisection 13.It is provided with blast pipe 14 on upper semisection 12, (plate-fin heat exchanger is for lower semisection 13 and heat-exchanger rig 2
One kind in heat-exchanger rig) feeder connection 21 connect.Upper semisection 12 and lower semisection 13 pass through upper shed 311 and under shed 312
UNICOM.
Fig. 4 and 3, which is respectively illustrated, to be had and the end socket without gas-liquid distribution member enters to liquid phase mix refrigerant
The influence of heat-exchanger rig.As shown in figure 3, when liquid phase mix refrigerant by the end socket without gas-liquid distribution member enters fashionable, gas
Do not separated with liquid phase mutually, but together enter heat-exchanger rig 2.
However, as shown in figure 4, when liquid phase mix refrigerant enter with gas-liquid distribution member end socket after, liquid phase
Mix refrigerant is introduced into gas-liquid distributor chamber 31.Refrigerant needs that by under shed 312 heat-exchanger rig 2 could be entered.Due under
Opening 312 is in downward funnel-form, and there is certain hopper level so that two-phase fluid helical flow, increases flow distance,
And funnel-form illustrates outlet diameter from large to small, refrigerant by when can by the extruding of outlet diameter from large to small,
Under the tension force and Action of Gravity Field of liquid refrigerant, gas refrigerant not readily passes through narrow hopper outlet.Then gas system
Cryogen rises, and flows into upper semisection 12 by upper shed 311, is discharged from blast pipe 14；Liquid refrigerant is downward through under shed
312, into lower semisection 13, enter from feeder connection 21 and exchanged heat in heat-exchanger rig 2, it is achieved thereby that point of gas phase and liquid phase
From the problem of efficiently solving refrigerant air-liquid into heat-exchanger rig passage mutually impure caused heat-exchanger rig hydraulic performance decline.
Furthermore, it is possible to be set according to actual conditions are further to the present invention.Such as：Inlet honeycomb duct 32 is by stainless steel
Plate is processed, and is consistent with the shell material of heat-exchanger rig 2.Due to being greater than 2mPa high-pressure space, entrance in housing
The pipe thickness of mozzle 32 needs to be determined according to actual pressure.The diameter of inlet honeycomb duct 32 and the refrigerant of heat-exchanger rig 2
Inlet diameter is equal.
Trapezoidal dividing plate 33 is processed by aluminium sheet or stainless steel plate, is consistent with the material of the housing of heat-exchanger rig 2.Ladder
The thickness needs of shape dividing plate 33 determine that the inner space size for neglecting end socket 1 greatly is determined, trapezoidal dividing plate 33 according to actual pressure
Central shaft is coaxially distributed with the entrance center axle of end socket 1, and in the top end opening of trapezoidal dividing plate 33, i.e. upper shed 311.Upper shed
Tube wall of 311 edge not with inlet honeycomb duct 32 is contacted, and leaves 30-50mm spacing.
Plane clapboard 34 is processed by aluminium sheet or stainless steel plate, is consistent with the material of the housing of heat-exchanger rig 2.It is flat
The thickness of face dividing plate 34 needs to be determined according to actual pressure, and the size of plane clapboard 34 is identical with the top view cross section of end socket 1, plane every
The bottom welding and sealing at the edge of plate 34 and trapezoidal dividing plate 33, and the bottom surface of plane clapboard 34 keeps 50- with feeder connection 21
80mm distances.Funnelled shaped entrance on plane clapboard 34, i.e. under shed 312, are processed by aluminium sheet or stainless steel plate, and thickness is needed
To be determined according to actual pressure, be highly 20-40mm.
