Description
Technical field
The utility model relates to a kind of a kind of effective multistage diffusions of auxiliary body more particularly to evaporator feed flow of evaporator
Connector.
Background technique
Evaporator is the critically important component in four big parts that freezes, and condensation " liquid " body of low temperature is and outer by evaporator
The air on boundary carries out heat exchange, and " gas " changes heat absorption, achievees the effect that refrigeration.The structure of evaporator includes that more of internal setting follow
Ring liquid feeding pipeline, one provides refrigerant, is equipped with multiple heat exchanger fins, on liquid feeding pipeline to reach heat exchange operation.
It is high to be sent into fluorine chlorine that connection inlet tube is concentrated in usual liquid feeding pipeline one end, and the other end connects outlet tube, due to evaporation
Circulation line in device is more parallel settings, and inlet tube only has one, so how to recycle an inlet tube with more
Liquid supply pipe connection is a problem of this field, and the most common way is exactly to be sealed one end using an elongated inlet tube,
Circulating feeding liquid pipe is sequentially communicated inlet tube side, one end feed liquor then never sealed, this position for resulting in inner inlet close
Flow stream pressure is big, and distal end is small, causes amount of liquid in each circulation pipe inconsistent, to reduce refrigeration effect.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of evaporator feed flow effective multistage diffusion
Connector after the refrigerant for being sent into input pipe carries out multistage diffusion, then has annular feed flow head to be sent in each circulation line, real
Existing equilibrium feed flow.
To achieve the above object, the utility model proposes following technical solutions: a kind of effective multistage diffusion of evaporator feed flow
Connector, the input pipe for being D1 including diameter, the level-one diffuser that end is D2 integrally formed with diameter, in level-one diffuser
The second level diffuser that end is D3 integrally formed with diameter, and annular feed flow head is installed in second level diffuser pipe tips, end
Annular surface on be equipped at intervals with multiple liquid outlets, by multiple inlet tubes of piping connection evaporator, it is described annular feed flow head tool
There is inner and outer wall, outer wall is connected with second level diffuser, and inner wall is enclosed construction, and has curved bottom, inner wall
It is formed between outer wall for pendular ring, so that the refrigerant that input pipe enters steps into level-one diffuser, is entered after second level diffuser
Evaporator is sent into for pendular ring, and from liquid outlet.
Preferably, the annular feed flow head section be it is tubaeform, the diameter of outlet end is greater than the diameter of liquid feeding end, and its
Tilt angle with horizontal plane is 45 ~ 60 °.
Preferably, the perfusion tube, the diameter Relationship between level-one diffuser and second level diffuser is D3 > D2 >
D1。
Preferably, using arc transition between the input pipe and level-one diffuser, level-one diffuser and second level are spread
Arc transition is used between pipe.
Compared with prior art, the effective multistage diffusion connector of the revealed a kind of evaporator feed flow of the utility model, tool
It has the advantages that:
The level-one diffusion incrementally increased using diameter and second level diffuser so that the refrigerant being sent into input pipe first fill to
In diffuser, by being sent into each liquid outlet for pendular ring, it can be ensured that the amount of liquid of each liquid outlet is the same, so as to protect
It is consistent to demonstrate,prove refrigerant liquid measure in each circulation pipe, it is ensured that refrigeration effect；
For feed flow head using the structure of the horn mouth cooperation annular of diffusion, it can effectively increase the size in outlet end face,
To meet the feed flow of enough circulation pipes；
Using the structure of inside and outside wall liquid feeding channel is reduced on feed flow head, to promote the fluid pressure of supply opening
Value, and inner wall bottom uses arc structure, so that the liquid in diffuser is smoothly flow in annular liquid feeding channel.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model；
Fig. 2 is the side sectional view of the utility model.
Specific embodiment
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model embodiment is carried out clear, complete
Description.
As shown in Figure 1 and 2, the effective multistage diffusion connector of the revealed a kind of evaporator feed flow of the utility model, is mounted on
Between refrigerant inlet tube and more circulating feeding liquid pipelines of evaporator, the input pipe 1 for being D1 including diameter, end is integrally formed
There is diameter for the level-one diffuser 2 of D2, the second level diffuser 3 for being D3 integrally formed with diameter in level-one diffuser pipe tips, and
Second level diffuser pipe tips are equipped with annular feed flow head 4, and multiple liquid outlets 5 are equipped at intervals on the annular surface of end, pass through pipeline
Multiple inlet tubes of evaporator, the perfusion tube are connected, the diameter Relationship between level-one diffuser and second level diffuser is D3
> D2 > D1, and 6 transition of circular arc is used between the input pipe and level-one diffuser, between level-one diffuser and second level diffuser
Using arc transition.
The annular feed flow head section be it is tubaeform, the diameter of outlet end is greater than the diameter of liquid feeding end, has inner wall 7 and outer
Wall 8, outer wall is connected with second level diffuser, horizontal by 45 ~ 60 ° of inclination, and inner wall and outside wall parallel, there is arc
Closed bottom 9, annular liquid feeding channel 10 is formed between inner wall and outer wall, so that the refrigerant that input pipe enters steps into one
Grade diffuser enters annular liquid feeding channel after second level diffuser, and is sent into evaporator from liquid outlet.
The technology contents and technical characteristic of the utility model have revealed that as above, however those skilled in the art still may be used
Can teaching based on the utility model and announcement and make various replacements and modification without departing substantially from the spirit of the present invention, therefore, this
Utility model protection range should be not limited to the revealed content of embodiment, and should include the various replacements without departing substantially from the utility model
And modification, and covered by present patent application claim.
