The length, the pipe diameter and the number of the branch pipes 31 are not limited, and only the requirement that the pulsating pressure of each refrigerant entering the branch pipes 31 can form a phase difference is met. After confluence is carried out again, pulsating pressure of each refrigerant strand can influence each other and interfere each other and offset each other, so that the pulsating pressure of the converged refrigerants is weakened, vibration of the refrigerants which is transmitted to the pipeline due to the pulsating pressure and further transmitted to the indoor unit of the air conditioner is reduced, and vibration noise of the indoor unit of the air conditioner is effectively weakened.
The outdoor unit of the air conditioner of the present invention is provided with the flow divider 30 in the exhaust pipe 50 and/or the return pipe 60, so that the refrigerant flowing out of the compressor unit 10 is divided into a plurality of branch pipes 31 and then collected, or the refrigerant which is about to flow into the compressor unit 10 is divided into a plurality of branch pipes 31 and then collected, the refrigerant is divided into a plurality of branch flows and flows into each branch pipe 31, the pulsating pressure of each refrigerant in each branch pipe 31 forms a certain phase difference under the influence of the length difference or the pipe diameter difference of the branch pipes 31 and the like, so that after the refrigerant flows out of the branch pipes 31 and is converged, the pulsating pressures of the different sections with phase difference affect and interfere with each other and cancel each other, therefore, the pulsating pressure of the converged refrigerant is weakened, the vibration of the refrigerant, which is transmitted to the pipeline due to the pulsating pressure and further transmitted to the indoor unit of the air conditioner, is reduced, and the vibration noise of the indoor unit of the air conditioner is effectively weakened; furthermore, the utility model discloses a pulsating pressure interact through each burst of refrigerant tributary interferes and weakens whole pulsating pressure, consequently effectively eliminates the noise homoenergetic to different frequency bands, has improved air condensing units's noise reduction.
Further, as shown in fig. 2 and 3, the flow divider 30 further includes a flow dividing joint 32 and a flow collecting joint 33, the flow dividing joint 32 is communicated with the air inlet ends of the plurality of flow dividing branch pipes 31, and the flow collecting joint 33 is communicated with the air outlet ends of the plurality of flow dividing branch pipes 31. In the present embodiment, two ends of the plurality of branch pipes 31 are respectively communicated with the collecting joint 33 and the branch joint 32, and the branch pipes 31, the collecting joint 33 and the branch joint 32 can be fixed by welding. The flow dividing joint 32 and the flow collecting joint 33 are used for being fixedly communicated with the pipeline of the exhaust pipeline 50 and/or the gas return pipeline 60 so as to realize the fixed connection of the flow divider 30 and the pipeline of the exhaust pipeline 50 and/or the gas return pipeline 60, and the flow divider 30 is simpler and more convenient to install.
Further, the length of at least one of the branch pipes 31 is greater or less than the length of the other branch pipes 31. In this embodiment, the length of at least one of the branch pipes 31 is different from the lengths of the other branch pipes 31, and the length of the branch pipe 31 affects the pulsating pressure of the refrigerant, so that the pulsating pressures of the refrigerants flowing through the branch pipes 31 having different lengths can effectively generate a phase difference, and the pulsating pressures of the merged refrigerants are influenced and interfered with each other and offset each other, so as to weaken the overall pulsating pressure of the merged refrigerants, and weaken the vibration transmitted from the refrigerants to the pipeline. In an embodiment, the length of any branch line 31 is greater than or less than the lengths of the other branch lines 31, that is, the lengths of the branch lines 31 are different, so that the pulsating pressures of the refrigerants flowing through the branch lines 31 are different, and the pulsating pressures of the merged refrigerants are effectively promoted to influence and interfere with each other, so that the overall pulsating pressure of the merged refrigerants is further reduced, and the vibration transmitted to the pipeline by the refrigerants is reduced.
In practical applications, the length of the branch pipes 31 is 300mm to 800mm, that is, for a plurality of branch pipes 31 with different lengths, the shortest branch pipe 31 may be 300mm in length, and the longest branch pipe 31 may be 800mm in length. If the length of the branch pipes 31 is less than 300mm, the refrigerant flows to the collecting position too fast, and cannot effectively generate pulsating pressure phase difference with the refrigerant in other branch pipes 31 and interfere with each other; if the length of the branch pipe 31 is greater than 800mm, the occupation of the whole splitter 30 on the space in the outdoor unit of the air conditioner will be increased; therefore, the length of the branch pipes 31 is set to 300mm to 800mm, which not only effectively ensures the damping and noise reducing effects of the flow divider 30, but also reduces the space occupation of the flow divider 30 in the air conditioner outdoor unit, so that the internal structure of the air conditioner outdoor unit is more compact.
Further, the pipe diameter of at least one of the branch pipes 31 is larger or smaller than the pipe diameters of the other branch pipes 31. In this embodiment, the pipe diameter of at least one of the branch pipes 31 is different from the pipe diameters of the other branch pipes 31, and the pipe diameter of the branch pipe 31 affects the pulsating pressure of the refrigerant, so that the pulsating pressures of the refrigerants flowing through the branch pipes 31 with different pipe diameters can effectively generate a phase difference, and the pulsating pressures of the merged refrigerants are influenced and interfered with each other and offset with each other, thereby weakening the overall pulsating pressure of the merged refrigerants and weakening the vibration transmitted from the refrigerants to the pipeline. In an embodiment, the pipe diameter of any branch pipe 31 is greater than or less than the pipe diameters of the other branch pipes 31, that is, the pipe diameters of the branch pipes 31 are different, so that the pulsating pressures of the refrigerants flowing through the branch pipes 31 are different, and the pulsating pressures of the merged refrigerants are effectively promoted to influence and interfere with each other, so that the overall pulsating pressure of the merged refrigerants is further reduced, and the vibration transmitted to the pipeline by the refrigerants is reduced.
In practical applications, the pipe diameters of the branch pipes 31 are 2mm to 5mm, that is, for a plurality of branch pipes 31 with different pipe diameters, the pipe diameter of the shortest branch pipe 31 may be 2mm, and the pipe diameter of the longest branch pipe 31 may be 5 mm. If the pipe diameter of the branch flow dividing pipe 31 is smaller than 2mm, the flux of the branch flow dividing pipe 31 is too small, and the flow velocity of the refrigerant is influenced, so that the normal flow of the whole refrigerant is influenced; if the pipe diameter of the branch pipe 31 is larger than 5mm, the occupation of the whole flow divider 30 to the space in the outdoor unit of the air conditioner is increased; therefore, the length of the branch pipe 31 is set to 2mm to 5mm, so that the normal flow of the refrigerant and the vibration and noise reduction effect of the flow divider 30 can be effectively ensured, the space occupation of the flow divider 30 in the air conditioner outdoor unit can be reduced, and the internal structure of the air conditioner outdoor unit is more compact.
Further, the number of the branch pipes 31 is 4 to 8. In the present embodiment, the number of the branch flow lines 31 is preferably 6; if the number of the branch flow dividing pipes 31 is less than 4, the number of the branch flows after the refrigerant is divided is too small, so that the mutual interference effect of the branch flows of the refrigerant after confluence is weaker, and the pulsating pressure of the refrigerant cannot be effectively reduced; if the number of the branch pipes 31 is greater than 8, the occupied space of the entire splitter 30 in the outdoor unit of the air conditioner may be increased, which is not favorable for the installation of the splitter 30; therefore, the number of the branch pipes 31 is set to 4 to 8, which not only effectively ensures the damping and noise reducing effect of the flow divider 30, but also reduces the space occupation of the flow divider 30 in the air conditioner outdoor unit, so that the internal structure of the air conditioner outdoor unit is more compact.
Further, as shown in fig. 1 and 2, the outdoor unit of an air conditioner further includes a four-way valve 20, and the discharge line 50 and the return line 60 are communicated with the four-way valve 20. In this embodiment, the four-way valve 20 is further communicated with the indoor heat exchanger and the outdoor heat exchanger, and the four-way valve 20 is used for realizing the switching communication between the air outlet and the air return opening of the compressor unit 10 and the indoor heat exchanger and the outdoor heat exchanger, thereby realizing the switching between the cooling mode and the heating mode of the air conditioner. For example, in a refrigeration mode of the air conditioner, the refrigerant is converted into high-temperature and high-pressure gas by the compressor unit 10, enters the outdoor heat exchanger through the four-way valve 20 to absorb and release heat, is converted into low-temperature and low-pressure liquid, enters the indoor heat exchanger to absorb and release heat and is converted into low-temperature and low-pressure gas, and flows back to the compressor unit 10 through the four-way valve 20, so that the refrigeration cycle of the refrigerant is realized. If the air conditioner is switched to the heating mode, the four-way valve 20 communicates the discharge port of the compressor unit 10 with the indoor heat exchanger and the return port of the compressor unit 10 with the outdoor heat exchanger, thereby realizing a heating cycle of the refrigerant.
Further, as shown in fig. 1 and 2, the outdoor unit of an air conditioner further includes a low pressure valve 40, and the low pressure valve 40 is disposed in the return air pipe 60 and communicates with the flow divider 30. In this embodiment, in combination with the above-mentioned embodiment of the four-way valve 20, the low-pressure valve 40 is disposed between the four-way valve 20 and the air return port of the compressor unit 10, the air inlet of the low-pressure valve 40 is communicated with the air outlet of the four-way valve 20, and the air outlet of the low-pressure valve 40 is communicated with the air return port of the compressor unit 10, so as to prevent the refrigerant whose air pressure does not satisfy the preset condition from flowing back to the compressor unit 10 to affect the operation of the compressor unit 10, thereby improving the operation stability of the compressor unit 10.
