Description

A kind of fluid injection device

Technical field

This utility model relates to energy technology field, is specifically related to a kind of fluid injection device.

Background technology

Air-conditioning is in kind of refrigeration cycle, in addition to condensation link is high pressure, and other each links of system Belong to equal pressure condition.In order to guarantee refrigerant fluid reasonable distribution to condenser, at present Technique in the mode of commonly used compressor realize supercharging.That is: air-conditioning is when refrigerating operaton, Compressor is delivered to higher-pressure region cooling after low-pressure area extracts compression cold-producing medium and is condensed so that The cold-producing medium of low-temp low-pressure pressurizes after being sucked by compressor and becomes the refrigerant gas of High Temperature High Pressure. And compressor generally has following defects that startup needs to consume a large amount of mechanical energy, energy consumption is bigger； Structure is relative complex, adds manufacturing cost.

Utility model content

In view of this, this utility model provides a kind of fluid injection device, is used for fluid from low Pressure side injection is to high-pressure side.

The technical solution adopted in the utility model particularly as follows:

A kind of fluid injection device, including housing and be located in described housing, along injection side To the gateway unit being sequentially arranged, chamber unit and jet；Wherein:

Described gateway unit includes driving fluid entrance and is placed in outside described driving fluid entrance Driven fluid entrance；

Described chamber unit includes mixing chamber and the drainage device of connection；Wherein:

The driven fluid of initial end is connected with mixing chamber through described driven fluid entrance；

External air flow is connected with mixing chamber through driving fluid entrance；

The downstream of described drainage device is connected with described jet, and described jet is connected to target End.

In above-mentioned fluid injection device, external air flow enters blower fan through fluid intake, blower fan Nozzle tip is connected with driving fluid entrance.

In above-mentioned fluid injection device, described blower fan is axial flow blower, described axial flow blower warp Driving fluid entrance accesses the bottom of mixing chamber.

In above-mentioned fluid injection device, described drainage device includes the collapsible tube being sequentially connected, mixes Closing pipe and anemostat, the air stream outlet of described mixing chamber engages with collapsible tube, described anemostat It is connected to described jet.

This utility model produces and provides the benefit that:

Fluid injection device of the present utility model is particularly suited under middle pressure ring border, can be applicable to system In the applied environments such as SAPMAC method, the most alternative compressor or pressure regulator valve, it is used for Improve refrigerating efficiency.

Accompanying drawing explanation

When considered in conjunction with the accompanying drawings, it is possible to be more completely more fully understood that this utility model.This place The accompanying drawing illustrated is used for providing being further appreciated by of the present utility model, and embodiment and explanation thereof are used In explaining this utility model, it is not intended that improper restriction of the present utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawings and the technical solution of the utility model is made further details of by embodiment Explanation.

Fluid injection device as shown in Figure 1, including housing 7 and be located in housing 7, Gateway unit, chamber unit and the jet 6 being sequentially arranged along injection direction；Wherein:

Gateway unit includes driving fluid entrance 4 and is placed in the quilt outside driving fluid entrance 4 Driving fluid entrance 2；

Chamber unit includes mixing chamber 3 and the drainage device 5 of connection；Wherein:

The driven fluid of initial end 01 is connected with mixing chamber 3 through driven fluid entrance 2；

External air flow is connected with mixing chamber 3 through driving fluid entrance 4；Specifically:

External air flow enters blower fan through fluid intake 1, and the nozzle tip of blower fan enters with driving fluid Mouth 4 is connected；

The downstream of drainage device 5 is connected with jet 6, and jet 6 is connected to destination end 02.

Drainage device 5 farther includes collapsible tube, mixing tube and the anemostat being sequentially connected, mixing The air stream outlet of room 3 engages with collapsible tube, and anemostat is then connected to jet 6.

Blower fan is preferably axial flow blower, the most small-sized axial flow blower, and concrete installation site is Access the bottom of mixing chamber 3, there are low in energy consumption, low, energy-conserving and environment-protective of rapid heat dissipation, noise etc. excellent Point.

Additionally, mixing chamber 3, drainage device 5, jet 6 and driven fluid entrance 2 and draw The cross sectional shape of jet body entrance 4 all elects circular configuration as, the resistance during reducing injection Power.

The work process of above-mentioned fluid injection device particularly as follows:

External air flow enters after blower fan makes airflow speed increasing by fluid intake 1, as driving fluid Mixing chamber 3 is entered, the driving fluid of speedup through being placed in the driving fluid entrance 4 of blower fan nozzle tip With the target that the driven fluid of the low pressure of initiating terminal 01 is mixed to form mesohigh in mixing chamber 3 Air-flow, and it is ejected to mesohigh by jet 6 further after target airflow is pushed drainage device 5 Destination end 02, i.e. complete one action.

It can be seen that fluid injection device not only induction efficiency of the present utility model is high, Er Qiejie Structure is simple, reduces production cost, has good promotional value.

Above in association with accompanying drawing, embodiment of the present utility model is explained, herein Accompanying drawing is used to offer and is further appreciated by of the present utility model.Obviously, the foregoing is only this Utility model preferably detailed description of the invention, but protection domain of the present utility model is not limited to This, any be to one skilled in the art can readily occur in, essentially without disengaging Change of the present utility model or replacement, within being also all contained in protection domain of the present utility model.
