Description

TECHNICAL FIELD

[0002] In the prior art, a distributor is usually used to distribute or collect refrigerant. When an air conditioner is in a heating mode, refrigerant flows from a main pipe into the distributor, and then flows into each branch pipe of a heat exchanger through the distributor. In this distribution process, the refrigerant enters the inside of an inner cover of the distributor through a bottom interface of the distributor, the inner cover has a plurality of distribution channels with small flow areas, and the refrigerant is distributed to each top interface of the distributor through the distribution channels. When the air conditioner is in a cooling mode, the refrigerant after heat exchange in the heat exchanger flows out from each branch pipe, and then flows into the main pipe after being collected in the distributor. In this collection process, the refrigerant in the prior art enters a cavity through a top interface, and then flows out through the distribution channels on the inner cover after being hit by the inner cover. The flow area of the distribution channels is small, which greatly reduces the flow rate of the refrigerant in this process, and causes a large pressure drop of the refrigerant, thereby affecting the operation performance of the air conditioning unit.

[0022] BRIEF DESCRIPTION OF DRAWINGS Figures 1 to 3 As shown in the drawings, according to the embodiments of the present application, a distributor includes a first channel 1, a second channel 2 and a valve, the first channel 1 is arranged opposite to the second channel 2, the valve is arranged between the first channel 1 and the second channel 2, when the fluid in the first channel 1 flows to the valve and the pressure of the fluid in the first channel 1 on the valve is greater than the opening pressure of the valve, the valve opens to enable the fluid in the first channel 1 to flow into the second channel 2. By arranging the first channel 1 opposite to the second channel 2 and arranging the valve between the first channel 1 and the second channel 2, the refrigerant in the prior art can be prevented from directly hitting the lower end cover plate, the pressure drop generated when the refrigerant flows through the distributor can be effectively reduced, and the good operation performance of the air conditioning unit can be ensured. In the simulation analysis, the distributor in the embodiment can reduce the pressure drop by 87.3%.

[0023] In some embodiments, the valve is used to open or close the flow path between the first channel 1 and the second channel 2, thereby connecting or blocking the first channel 1 and the second channel 2.

[0024] In some embodiments, when the distributor is arranged in the air-cooled heat pump unit and the air-cooled heat pump unit is in a refrigeration working condition, the first channel 1 is connected with the condenser, the refrigerant condensed by heat exchange of the condenser flows out from each branch pipe of the condenser, and then flows into the second channel 2 after converging in the distributor.

[0025] In some embodiments, the distributor is a micro-pressure-difference refrigerant distributor.

[0026] In some embodiments, in the distributor, the internal space of the distributor near the side of the valve close to the first channel 1 is a mixing chamber, and the internal space of the distributor near the side of the valve close to the second channel 2 is a liquid collecting chamber.

[0027] The distributor further includes a shell 4, the shell 4 is provided with a mounting cavity, the valve is arranged in the mounting cavity, and the mounting cavity provides a mounting position for the valve, thereby ensuring that the valve is stably arranged in the shell 4.

[0028] In some embodiments, the shell 4 is a hollow cylindrical structure.

[0029] The valve includes a valve body 31 and an elastic member, the valve body 31 is hinged to the inner wall of the mounting cavity, and the elastic member is arranged on the valve body 31 and the inner wall of the mounting cavity. When the pressure of the fluid in the first channel 1 on the valve is less than the opening pressure of the valve, the elastic member can drive the valve body 31 to close the flow path between the first channel 1 and the second channel 2. By arranging the elastic member, the valve can stably open or close the flow path between the first channel 1 and the second channel 2 according to the opening pressure.

[0030] In some embodiments, the elastic member is a torsion spring.

[0031] In some embodiments, the opening pressure of the valve can be adjusted by changing the elastic force of the spring by replacing the spring model.

[0032] In some embodiments, one end of the torsion spring is arranged on the inner wall of the mounting cavity, and the other end is arranged on the valve body 31.

[0033] In some embodiments, the valve body 31 is rotated to the side where the second channel 2 is located to open, and the valve body 31 is rotated to the side where the first channel 1 is located to close.

[0034] When the valve body 31 is closed, the end face of the valve body 31 close to the second channel 2 is a first end face, a limiting piece 32 is arranged on the valve body 31, the limiting piece 32 is arranged on the first end face, and the limiting piece 32 protrudes from the first end face. By arranging the limiting piece 32, when the valve body 31 is opened to the limit position, the end of the limiting piece 32 away from the first end face abuts against the inner wall of the shell 4, limiting the opening angle of the valve body 31, and preventing the valve body 31 from being opened excessively.

[0035] In some embodiments, the limiting piece 32 extends in the axial direction of the dispenser.

[0036] In some embodiments, by arranging the length of the limiting piece 32, the maximum opening angle of the valve body 31 can be limited.

[0037] The limiting piece 32 is arranged perpendicularly to the first end face.

[0038] In some embodiments, the limiting piece 32 is in the shape of a cylinder.

[0039] In some embodiments, the limiting piece 32 is arranged at the center position of the valve body 31.

[0040] The dispenser further comprises a shell 4, and a mounting table 41 is arranged on the inner wall of the shell 4 in the circumferential direction of the shell 4, and the valve is arranged on the mounting table 41. By arranging the mounting table 41, a stable mounting position can be provided for the valve.

[0041] In some embodiments, the mounting table 41 is annular, and the valve is arranged inside the inner circle of the mounting table 41.

[0042] In some embodiments, the valve is hinged to the inner wall of the mounting table 41.

[0043] In some embodiments, the space inside the annulus circumscribed by the mounting table 41 is the mounting cavity.

[0044] The third channel 42 is arranged along the axial direction of the distributor on the mounting table 41, and is connected with the first channel 1 and the second channel 2 respectively. When the fluid flows into the distributor from the second channel 2, the fluid flows into the first channel 1 from the third channel 42. By arranging the third channel 42, a flow path is provided for the refrigerant to flow from the second channel 2 to the first channel 1. When the distributor is arranged in the air-cooled heat pump unit and the air-cooled heat pump unit is in the heating mode, the refrigerant flows into the liquid collection chamber of the distributor from the second channel 2, and the liquid level of the refrigerant in the distributor rises when the pressure rises. The refrigerant flows into the mixing chamber through the third channel 42. In this process, the kinetic energy of the refrigerant increases due to the sudden reduction of the flow area, and the flow rate increases. When passing through the third channel 42, the two openings of the third channel 42 form a pressure difference. The high-speed refrigerant generates vortex after entering the mixing chamber, so that the gas-liquid two-phase refrigerant is fully mixed, and then flows out uniformly along the first channel 1.

[0045] The number of the first channels 1 is multiple, and the number of the third channels 42 is multiple, so as to increase the flow area of the first channels 1 and the third channels 42, and ensure that the refrigerant flows out smoothly.

[0046] As an embodiment, the number of the first channels 1 is 5, and the number of the third channels 42 is 8.

[0047] As another embodiment, the number of the first channels 1 is multiple, the number of the third channels 42 is the same as that of the first channels 1, and the third channels 42 are arranged one by one corresponding to the first channels 1. By arranging multiple third channels 42 and arranging the third channels 42 one by one corresponding to the first channels 1, it is ensured that the refrigerant in the mixing chamber can flow out more smoothly.

[0048] Specifically, the number of the first channels 1 and the number of the third channels 42 are both 5.

[0049] The multiple third channels 42 are arranged uniformly along the circumference of the valve, so as to ensure that the refrigerant flow in each third channel 42 is similar, and the refrigerant stably flows through the distributor.

[0050] In another aspect of the embodiment, an air conditioner is provided, which comprises the above-mentioned distributor.

[0051] The distributor provided in the embodiment of the present application and the air conditioner comprising the same can reduce the pressure drop generated when the refrigerant flows through the distributor, and ensure good operation performance of the air conditioner unit.

[0052] It is easy for those skilled in the art to understand that the above-mentioned advantageous modes can be freely combined and superimposed without conflict.

[0053] The above merely preferred embodiments of the present application are not used to limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application. The above is merely the preferred embodiment of the present application, it should be pointed out that, for the ordinary skilled in the art, without departing from the technical principle of the present application, a number of improvements and variations can be made, these improvements and variations should also be considered as the protection scope of the present application.
