Abstract

Provided is a refrigerant flow distributor of an air-conditioner. The refrigerant flow distributor of the air-conditioner is mainly composed of a substrate with a relief-hole (3) and an enterclose (2). A nozzle (5) with a bellmouth orifice is inserted inside the enterclose. A fluid relief chamber(5) with a tapered thread(41) inside the inner wall is arranged between the nozzle and the relief-hole. The refrigerant enters the air-conditioner through a refrigerant inlet pipe after the air-conditioner works, and then generates eddy current in the fluid relief chamber (5) due to the effect of an internal thread after passing the nozzle, thus avioding the unevenness of the refrigerant flow caused by such factors as gas-liquid phase and weight. So an even and stable distribution of the refrigerant is achieved.

Description

A kind of refrigerant flow distributor of air-conditioner

Technical field

The utility model relates to the air-conditioner technical field, especially relates to a kind of cold medium flux uniform distributor of air-conditioner.

Background technology

Air-conditioner mainly is comprised of indoor and outdoor heat exchanger, compressor, controller and system management, the above air-conditioner of existing 2P is because the pipeline number of connection indoor and outdoor machine is more, in order to reduce flow and the pressure loss, refrigerant need to be divided into a plurality of branch roads, can cause like this cold medium flux difference in each branch road, the problem of distributing in order to solve cold medium flux, generally all a distributor can be installed in management, make it distributed uniform by regulating capillary pipe length or U-shaped pipe quantity again, thereby the assurance system can better move.

As shown in Figure 1, 2, the refrigerant flow distributor of existing air-conditioner is comprised of the matrix 1 with 3

tap holes

3 and 1 passage 2.Passage 2 connects refrigerant input pipe (not shown).Refrigerant flows to matrix 1 by the refrigerant input pipe, flows to tap hole 3 after passage 2 shuntings.Because refrigerant is very fast at passage 2 medium velocities, be assigned to flow in each tap hole 3 and inhomogeneous, and gas-liquid mixed is not identical yet, thereby causes that each branch road heat exchange of heat exchanger is inhomogeneous, air conditioner refrigerating or heating performance descend.

The utility model content

The utility model is to solve the uneven problem of cold medium flux distribution in each branch road of air-conditioner.

For this reason, the utility model provides a kind of refrigerant flow distributor of air-conditioner, main by the matrix composition with tap hole and passage, it is characterized in that: also be embedded with the nozzle with bellmouth orifice in the above-mentioned passage, have the fluid cushion chamber of tapered thread between aforementioned nozzle and tap hole for inwall.

When operation of air conditioner, refrigerant is entered by the refrigerant input pipe, by behind the nozzle, because the effect in fluid cushion chamber produces eddy current, thereby has avoided because the mass flow discrepancy that the factors such as liquid phase and weight cause, so has played the effect of uniform and stable distribution.

As a kind of optimization, in the refrigerant flow distributor of air-conditioner of the present utility model, tap hole is 3, and 3 tap hole terminal positions form the tapered protrusion with tapered thread.Like this, can increase the eddy current stroke of refrigerant in matrix, it is more even that gas-liquid two-phase is mixed.

Description of drawings

Further specify the utility model below in conjunction with the drawings and specific embodiments.

Fig. 1 is the structure cutaway view of the refrigerant flow distributor of existing air-conditioner;

The left view of the refrigerant flow distributor that Fig. 2 is shown in Figure 1;

Fig. 3 is the structure cutaway view of the refrigerant flow distributor of air-conditioner of the present utility model;

Fig. 4 is the left view of refrigerant flow distributor shown in Figure 3.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 3, Figure 4, this refrigerant flow distributor comprises matrix 1 and is installed in nozzle 5 on the passage 2 in the matrix 1 that an end of matrix 1 has 3 tap holes 3, be used for installing the capillary (not shown), the passage 2 of matrix 1 connects refrigerant input pipe (not shown).

Nozzle 5 similar jacket casings have and extend out the bellmouth orifice that inside contracts on passage 2.Also has fluid cushion chamber 5 at nozzle 5 and 3 of tap holes.Has tapered thread 41 on the inwall in fluid cushion chamber 5.Be provided with the tapered protrusion 6 with tapered thread on 3 tap hole 3 terminal centre positions.

When refrigerant flows to matrix 1 by the refrigerant input pipe, because the bell-mouthed expansion of nozzle 5, flow area increase, the flow velocity and the pressure that enter fluid cushion chamber 5 reduce, through tapered thread 41 effect after, form eddy current, flow to tap hole 3 after the gas-liquid two-phase mixing is more even.

In the present embodiment, because internal thread is adopted in fluid cushion chamber 5, so that the eddy current increasing, thereby avoided because therefore the mass flow discrepancy that the factors such as liquid phase and weight cause plays the effect of uniform and stable distribution.The tapered protrusion 6 with tapered thread in tap hole 3 terminal centre positions can further be optimized the circulation effect.

More than be one of embodiment of the present utility model, for those skilled in the art, do not spend performing creative labour, on the basis of above-described embodiment, can do multiple variation, can realize the purpose of this utility model equally.But this variation obviously should be in the protection domain of claims of the present utility model.
