Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figs 1-4, the utility model is welded-type impeller distributor.
The material of welded-type impeller distributor, including nozzle 1, impeller 2 and dispensing body 3, nozzle 1 is preferably copper or aluminium.Institute
There is the nozzle 1 stated input end 101 and mixing chamber 102, the middle part tapering transition section transition of the nozzle 1 inner cavity to be made to increase,
And the diameter of outlet end is more than the diameter of input end 101.Dispensing body 3 is equipped with outlet end, and the outlet end is equipped with multiple circles
The tap hole 301 of week distribution；The impeller 2 is equipped with guide vane 201；Both described nozzle 1 and dispensing body 3 pass through tunnel
Road stove is welded, and impeller is in the cavity between nozzle 1 and dispensing body 3.
The nozzle 1 further includes mixing chamber 102, and 102 lower section of the mixing chamber is equipped with impeller 2, and impeller 2 should be in 1 He of nozzle
It is put into the cavity before the welding of dispensing body 3.The input end 101 is connected to by mixing chamber 102 with the impeller 2, described
The diameter of mixing chamber 102 is more than the diameter of the input end 101.
Multiple same shapes and size are uniformly distributed on the impeller 2 and inclined guide vane 201.Into one
Step ground, the material of the impeller 2 is preferably stainless steel or copper, is formed through fine-edge blanking by plank, and the consistency of product is good, adds
Work precision can ensure.The angle of inclination of the guide vane 201 of the impeller 2 is 0<A<90°.Nozzle 1, impeller 2, dispensing body
3 structure and processing technology is simple, can effectively reduce production cost.
In the first embodiment, as depicted in figs. 1 and 2, the tap hole 301 is located in dispensing body 3.
In second of embodiment, as shown in Figure 3 and Figure 4, the tap hole 301 is located at outside dispensing body 3.
Preferably, the input end 101 of the nozzle 1 is provided with to position the first positioning hole of inlet tube, it is in institute
In the first inner chamber for stating input end 101, the first positioning hole and the first inner chamber coaxial line, the first positioning hole it is straight
Diameter is less than the diameter of the first inner chamber.Inlet tube is installed without auxiliary positioning, can be abutted directly against in first positioning hole, is positioned
It is simple and convenient, it is suitable for batch production processing.
When in use, the gas-liquid two-phase cold-producing medium of high-voltage high-speed is from the first of input end 101 for this welded-type impeller distributor
Inner cavity enters, and subsequently into mixing chamber 102, and impacts on impeller 2.Impeller 2 surface shape of the refrigerant in 102 inside of mixing chamber
At uniform eddy flow at a high speed, the gas-liquid two-phase in refrigerant is able to after being sufficiently mixed dynamically be evenly distributed again, from tap hole
301 shunt and go out, and realize that gas-liquid two-phase cold-producing medium is uniformly distributed.
What is carried out to refrigerant due to this welded-type impeller distributor is high speed rotation dynamic shunt, gravity factor pair
The influence of shunting is extremely small, therefore need not impose vertically-mounted, can be installed by any direction, effectively overcome existing distribution
Device needs vertically-mounted defect.
Since total flow area above impeller 2 is larger, therefore the flow velocity of refrigerant is not obviously improved, thus apparent inhibition
Noise.
In first embodiment, nozzle 1 and dispensing body 3 is all made of cold-heading or red technique of rushing shapes；In second embodiment,
Nozzle 1 is using cold-heading or red rushes that technique shapes, dispensing body 3 is shaped using cold stamping deep-drawing technique；The surface layer of the two
Strengthened, and its anti-fatigue performance and corrosion resistance are all significantly improved.
It is above preferred embodiments of the present invention, the scope of protection of the utility model is not limited, for ability
The modification and improvement that field technique personnel mentality of designing according to the present utility model is made, all should be considered as the protection of the utility model
Within the scope of.
