Description

Guide ring and refrigerant distributor adopting same

Technical Field

The utility model relates to a guide ring and a refrigerant distributor adopting the guide ring.

Background

At present, the refrigerant distributor is mainly used for the reposition of redundant personnel of refrigerant in the air conditioner heat exchanger, and current refrigerant distributor generally includes refrigerant inflow end and refrigerant outflow end, and the feed liquor passageway has been seted up to refrigerant inflow end, and a plurality of drain channels have been seted up to the refrigerant outflow end, and simultaneously, the middle part inside of refrigerant distributor still is formed with the liquid chamber of intercommunication feed liquor passageway and every drain channel, and the refrigerant flows in the liquid intracavity by the feed liquor passageway, through the reposition of redundant personnel effect, flows from a plurality of drain channels. Generally, in order to increase the pressure and the flow rate of the refrigerant and make the diversion effect better, a guide ring is usually arranged in the liquid inlet channel, and the pressure and the flow rate of the refrigerant are improved by using cylindrical orifices arranged on the guide ring.

However, one end of the current guide ring is a horn hole, and the other end of the current guide ring is a plane, so that welding is often easy to reverse in the welding process of the distributor, and the performance of the unit is affected.

Because the aperture of the cylindrical orifice is smaller than the inner diameter of the liquid inlet main pipe, the contact part of the guide ring and the liquid inlet main pipe can form a step structure, thereby generating reverse impact on the refrigerant, affecting the flow velocity of the refrigerant and affecting the flow dividing effect of the refrigerant.

The utility model discloses a uniform distributor for the flow of the refrigerant of an air conditioner, which is disclosed in the Chinese patent publication No. CN200920217121, wherein one end of a guide ring is a horn hole which is easy to misplace in the welding process, and the contact part of the guide ring and a liquid inlet main pipe can form a step structure, so that the reverse impact is generated on the refrigerant, the flow velocity of the refrigerant is influenced, and the flow distribution effect of the refrigerant is influenced.

The Chinese patent publication No. CN201721859984 discloses a 302 guide ring and a refrigerant distributor, wherein a lock catch mechanism is arranged at the bending part of a paper corner protector, the guide ring is provided with a horn hole at one end, the horn hole is easy to misorient in the welding process, because the guide ring is not provided with a pressurizing and conical reversing groove, the refrigerant flows to the capillary side, turbulence cannot be formed, and the refrigerant is often unevenly distributed due to the self gravity and the pressure influence when flowing through the distributor, so that the system capacity is directly reduced, and the reliability is reduced.

Example 2

As shown in fig. 1-4, a refrigerant distributor comprises a distributor 2, a guide ring 1 and a pipeline 3, wherein a step 21 matched with the guide ring 1 is formed at the inlet end of the distributor 2, the guide ring 1 is fixed on the step 21, the pipeline 3 is fixed on the other side of the guide ring 1 opposite to the step 21, the guide ring 1 comprises a guide ring body 11, the guide ring body 11 is of an annular structure with a through hole formed in the center, horn holes 12 with large outside and small inside are formed at the two ends of the through hole of the guide ring body 11, a throttling through hole 13 is formed between the two horn holes 12 through the through holes, the guide ring 1 and the pipeline 3 are fixed with the distributor 2 through welding, the horn holes 12 and the throttling through holes 13 are coaxially arranged, and the two horn holes 12 are symmetrically arranged at the two sides of the throttling through holes 13.

The working principle of the utility model is as follows:

the refrigerant enters from the pipeline 3, passes through one bell mouth 12 of the guide ring 1, then flows into the throttling through hole 13, finally flows out from the other bell mouth 12, enters the distributor 2, and is split into capillaries after being distributed.

When the pipeline 3 is communicated with the drainage section of the guide ring 2, the horn mouth of the drainage section can effectively reduce the height of a step formed at the joint between the pipeline 3 and the guide ring, so that the reverse impact on the refrigerant is effectively reduced, the pressure and the flow velocity of the refrigerant are increased, and the flow distribution effect of the refrigerant is further enhanced.

When the refrigerant is led into the throttling through hole 13 from the horn mouth 12, the throttling through hole 13 of the guide ring 1 is far smaller than the aperture of the connecting pipeline 3, and at the moment, the area of the refrigerant flowing through the throttling through hole is reduced under the same pressure condition, so that the flow velocity of the refrigerant is increased, and vortex is formed at the horn mouth of the guide ring 1, so that the refrigerant can uniformly flow out of each capillary tube.

Finally, it should be noted that the above list is only specific embodiments of the present utility model. Obviously, the utility model is not limited to the above embodiments, but many variations are possible. All modifications directly derived or suggested to one skilled in the art from the present disclosure should be considered as being within the scope of the present utility model.
