Description
Technical field
The utility model is related to Refrigeration ＆ Air-Conditioning dispenser technology field, and in particular to be a kind of built-in jet orifice plate
Distributor.
Background technology
For the distributor of Refrigeration ＆ Air-Conditioning pipe-line system, it should be realized gas-liquid two-phase cold-producing medium is sufficiently mixed after,
To evaporator uniformly, equally feed flow, but it is uneven and enter each branch road gas-liquid two-phase mixing usually occur in actual motion
Refrigerant flow it is unequal, both of which causes the difference of each branch road liquid supply rate, have impact on the heat-exchange performance of evaporator
Can, and then have influence on the service behaviour of whole refrigeration system.Therefore distributor performance is mainly reflected in distributing uniformity and noise two
Individual aspect.
Refrigeration ＆ Air-Conditioning in the market is typically distributed with distributor using central jet orifice plate distributor and venturi
Device carries out spray distribution.
Distributor as shown in Figure 6, jet agitation distribution, the major defect of this mode are carried out using central jet orifice plate
It is：（1）Due to not arranged effectively to gas-liquid two-phase cold-producing medium fluid-mixing, therefore the refrigeration that each branch road is assigned to
Agent flux isotropism is bad, so as to influence the heat transfer effect of whole air-conditioning system；
（2）When distributor is under non-vertical installment state, and it carries out multichannel distribution, because weight be present in liquid refrigerant
Power influences, it is difficult to accomplish that each branch road is evenly distributed or distributed by debugging mode, part heat exchanger tube is mismatched with refrigerant flow,
Heat exchange efficiency becomes worse；（3）High-voltage high-speed enters the gas-liquid two-phase cold-producing medium of distributor first by throttling pore, due to cutting
It face sudden contraction, increased dramatically the flow velocity of refrigerant, the refrigerant fluid column of high-voltage high-speed directly impacts cavity so that distributor
Produce very big liquid hammer noise.
Distributor as shown in Figure 5, using Venturi effect, the refrigerant come in from entrance, flowing through caliber contraction
Flow velocity improves when " aditus laryngis ", pressure reduces.After " aditus laryngis ", disorderly and serious Biased flow phenomenon gas-liquid two-phase freezes originally
Agent is grouped as the conformation of rules that center is liquid phase, circumference is gas phase.Pass through the effect of " liquid separation cone " again so that each branch road distribution
The refrigerant flow arrived is more impartial.Using seamlessly transitting between the contraction section and expansion segment of this inner skeleton runner, press
Power loss is small.But the major defect of this mode is：（1）The profile processing of inner flow passage is difficult, and cost is higher；（2）When point
When orchestration is in non-vertical installment state, equally existing the refrigerant bias current as caused by refrigerant gravity influences；（3）Limited by structure
System, the axial dimension of venturi distributor are relatively large.

Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As Figure 1-4, the utility model is the distributor of built-in jet orifice plate.
Distributor described in the present embodiment, including main body 1, the material of main body 1 is preferably copper or aluminium.Described main body 1 has
There are entrance point 101 and multiple ports of export 103, the middle part transition of tapering transition section 102 of the main body 1, increase inner chamber, and go out
The diameter at mouth end 103 is more than the diameter of entrance point 101.
The main body 1 also includes hybrid chamber 106, and the lower section of hybrid chamber 106 is provided with jet orifice plate 2, and jet orifice plate 2 should be
Using being put into before the process formings such as spinning in the hybrid chamber 106 of the main body 1, main body 1 carries out spinning and added tapering transition section 102
Hybrid chamber 106 is produced after work.The first inner chamber 104 of the entrance point 101 is connected by hybrid chamber 106 with the jet orifice plate 2,
The diameter of the hybrid chamber 106 is more than the diameter of the first inner chamber 104.
The upper surface of described jet orifice plate 2 is uniformly distributed the punching slit 201 of multiple same shapes and size, while
It is even to be distributed multiple same shapes and size and inclined guide vane 202.As shown in Fig. 2 the first embodiment is punched
Slit 201 is vortex wire.As shown in figure 3, second of embodiment punching slit 201 is radial.
Further, the material of described jet orifice plate 2 is preferably stainless steel or copper, is formed by sheet material through fine-edge blanking,
The uniformity of product is good, and machining accuracy can ensure.The angle of inclination of the guide vane 202 of described jet orifice plate 2 is 0<A<
90°.The structure and processing technology of main body 1 and jet orifice plate 2 are simple, can effectively reduce production cost.
Preferably, the entrance point 101 of the main body 1 is provided with to position the first positioning hole 105 of inlet tube, it is in
In the first inner chamber 104 of the entrance point 101, first positioning hole 105 and the coaxial line of first inner chamber 104, described the
The diameter of a positioning hole 105 is less than the diameter of the first inner chamber 104.Inlet tube is installed without auxiliary positioning, can be directly abutted
On the first positioning hole 105, positioning is simple and convenient, is processed suitable for batch production.
Preferably, the port of export 103 of the main body 1 is provided with to position the second positioning hole 107 of outlet, it is in
In the second inner chamber 108 of the port of export 103, second positioning hole 107 and the coaxial line of second inner chamber 108, described the

When in use, the gas-liquid two-phase cold-producing medium of high-voltage high-speed is from entrance point 101 for the distributor of this built-in jet orifice plate 2
First inner chamber 104 enters, and subsequently into hybrid chamber 106, and impacts on jet orifice plate 2.On the one hand, leading on jet orifice plate 2
Flow flowing of the blade 202 to refrigerant to play the guiding role, on the other hand, the punching slit 201 on jet orifice plate 2 is to refrigerant
Damping action is flowed.Under the collective effect of both, refrigerant is formed on the surface of jet orifice plate 2 of the inner side of hybrid chamber 106
Uniform eddy flow at a high speed, the gas-liquid two-phase in refrigerant are able to after being sufficiently mixed dynamically be evenly distributed again, from punching slit
The 201 shunting outflows of second inner chamber 108 through the port of export 103.Each bypass flow equalization, gas-liquid two-phase ratio phase so after shunting
Together, the generation of Biased flow phenomenon is effectively prevent, so that the temperature of each stream and cold are uniform in evaporator, hence it is evident that improve whole
The heat transfer effect of individual air-conditioning system.
What is refrigerant carried out due to the distributor of this built-in jet orifice plate 2 is rotation dynamic shunt at a high speed, therefore gravity
Influence of the factor to shunting is extremely small, therefore need not impose vertically-mounted, can be installed by any direction, effectively overcomes existing
There is distributor to need the defects of vertically-mounted.
Because total flow area above jet orifice plate 2 is larger, therefore the flow velocity of refrigerant is not obviously improved, thus substantially
Inhibit noise.
Because main distributor 1 uses rotary pressing processing, top layer is strengthened, and its anti-fatigue performance and decay resistance have
Significantly improve.
It is above preferred embodiment of the present utility model, the scope of protection of the utility model is not limited, for ability
The modification and improvement that field technique personnel make according to mentality of designing of the present utility model, should all be considered as protection of the present utility model
Within the scope of.
