Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
Embodiment one
In conjunction with shown in attached drawing 1-5, a kind of dispenser, basic system and existing dispenser substantially phase are present embodiments provided
It together, also include the components such as shell 1, air intake duct 2, exhaust pipe 3 and level-one gas-liquid separation mechanism 4.
As shown in Figure 1, the shell 1 of the present embodiment is formed by connecting by three parts, i.e. the upper shell 6 of top in figure, intermediate
Middle cylinder body 7 and lower section lower shell 8, upper shell 6, middle cylinder body 7 and lower shell 8 can by welding etc. modes be tightly connected,
So that forming the accommodating chamber of a sealing inside shell 1；The upper and lower ends of shell 1 are respectively equipped with opening, and the opening of upper end is used for
Above-mentioned air intake duct 2 is connected, the opening of lower end is for connecting above-mentioned exhaust pipe 3.
2 one end of air intake duct of the present embodiment is connected with 1 upper end of shell, and is connected with accommodating chamber, and the other end is located at shell
Outside body 1, for connecting evaporator.
3 one end of exhaust pipe of the present embodiment is protruded into accommodating chamber by 1 lower end of shell, particularly extend into the upper of accommodating chamber
Portion, it is outer with connect compressor (not shown) that the other end of exhaust pipe 3 is located at shell 1；The present embodiment according to attached drawing
Straight tube 9 of the exhaust pipe 3 by being located in shell 1 and the bend pipe 10 outside shell 1 form, the connection type of straight tube 9 and bend pipe 10
It can be and be detachably connected or integrally connected etc..
The level-one gas-liquid separation mechanism 4 of the present embodiment is mounted on accommodating chamber top, and it is common to can be existing dispenser
The structures such as screen modules, level-one gas-liquid separation mechanism 4 is for being filtered gas-liquid mixture, so that gas-liquid separation, enterprise
Liquid after separation flows into 1 bottom of shell of shell 1, and gas is transported to compressor by one end that exhaust pipe 3 is placed in shell 1
In cylinder.
But utility model people is had found by many experiments, still can in the gaseous refrigerant after screen modules separate
Liquid refrigerant is carried, although liquid refrigerant accumulates in cylinder lower part, liquid-gas interface still has a large amount of foam-like
Refrigerant, the liquid refrigerant that gaseous refrigerant carries this part foam shape enter compresser cylinder, lead to liquid hammer.
Therefore utility model people makes improvements, and second level gas-liquid separation mechanism is increased on the basis of existing dispenser
5, second level gas-liquid separation mechanism 5 is located at 4 lower section of level-one gas-liquid separation mechanism, can be to the incomplete mistake of level-one gas-liquid separation mechanism 4
The gas-liquid mixture of filter filters again, greatly improves gas-liquid separation effect, avoids liquid hammer problem.
Specifically, the second level gas-liquid separation mechanism 5 of the present embodiment is partition 12, accommodating chamber is divided into two by partition 12, and
Partition 12 is equipped with multiple filter hole 13, and the partition 12 with filter hole 13 not only can be effectively to coming from net-filter assembly
The gas-liquid mixture not being kept completely separate carries out second and separates, and it is mixed that bring foam-like gas-liquid can be taken from liquid-gas interface
It closes object and carries out third time separation through partition 12, the foam of foam-like gas-liquid mixture is smashed in third time separation, on gas is direct
The upper end of exhaust pipe 3 is risen to, liquid enters 1 bottom of shell, can greatly reduce the possibility that liquid refrigerant enters compressor
Property, the risk of compressor liquid hammer is reduced, and then anti-slip limiting plate and roller are detached from, improves compressor performance and reliability.
The present embodiment is also equipped with the sealing structure being connected with 1 inner wall of shell, the sealing structure in the outer peripheral edge of partition 12
It can be sealing ring etc., the outer peripheral edge for being also possible to partition 12 as shown in Figure 1 has the side wall 11 upwardly extended, outer peripheral edge
It is tightly connected with 1 inner wall of shell.
In addition, utility model people has found again, if it is desired to which second level gas-liquid separation mechanism 5 plays good gas-liquid separation effect
The position of fruit, partition 12 is most important, therefore applicant improves installation site of the partition 12 in shell 1: such as Fig. 1 institute
Show, by exhaust pipe 3 protrude into shell 1 one end and second level gas-liquid separation mechanism 5 distance definition be H1, by second level gas-liquid segregating unit
The Distance positioning of structure 5 and 1 bottom wall of shell is H2, wherein 1 < H1/H2 < 1.6.The design can guarantee second level gas-liquid separation mechanism 5
Good gas-liquid separation effect is played, avoids the gas-liquid mixture after level-one gas-liquid separation mechanism 4 separates without second level mistake
Filter just enters exhaust pipe 3.
Specifically, there are many structure types of the filter hole 13 of the partition 12 of the present embodiment, such as shown in Fig. 2-4, filtering
The shape in hole 13 can be round, triangle or diamond shape etc., and in order to advanced optimize gas-liquid separation effect, the present embodiment
The maximum length of filter hole 13 is designed as 0.5mm-2mm, it should be noted that " maximum length " of the present embodiment referred to
The maximum distance of two opposite point of the filter opening 13 on the section for being parallel to partition 12, can be bevel edge side by taking triangle as an example
It is long, can be by taking diamond shape as an example two it is opposite and apart from maximum endpoint.
In addition, the present embodiment is also to the quantity of filter hole 13, the spacing in adjacent head hole 13 in order to advanced optimize effect
Specific restriction is made, i.e. the minimum range of the two neighboring filter hole 13 of the present embodiment is more than or equal to 2mm；The filtering of the present embodiment
The quantity in hole 13 is more than or equal to 60.
In conjunction with shown in attached drawing 5, the refrigerant flow of the present embodiment as shown by the arrow, specifically:
When air-conditioning work, the gas-liquid mixture of the low-temp low-pressure come from A/C evaporator enters through dispenser air inlet pipe, passes through
Level-one gas-liquid separation mechanism 4 is separated, and most of gaseous refrigerant enters in exhaust pipe 3, and is entered by exhaust pipe 3
In compresser cylinder, and 1 bottom of shell is stayed in after the liquid refrigerant separation carried in gaseous refrigerant；And it is separated through filter screen
Gas-liquid mixed refrigerant afterwards can carry out second of separation after encountering partition 12, and liquid refrigerants is made to enter 12 lower part of partition sky
Between, gaseous refrigerant enters the cylinder of compressor through steel pipe.On the other hand, the gas-liquid of 12 lower space liquid refrigerant of partition point
Interface still has a large amount of foam-like refrigerant, and the liquid refrigerant that gaseous refrigerant carries this part foam shape can make
Bubble burst carries out third time separation, is further ensured that into the mass dryness fraction of the refrigerant of steel pipe, prevents liquid hammer.
