Description

Technical Field

[0001] This application relates to the field of air conditioning piping technology, and more specifically to an air conditioning manifold assembly. Background Technology

[0002] The air conditioning manifold is a crucial component of an air conditioning system, used to collect and distribute refrigerant gas to ensure the system's efficient operation. In industrial production, it is vital to the stability and energy efficiency of the air conditioning system. The air conditioning manifold is a key functional component of the air conditioning system; its core function is to collect the gaseous medium within the evaporator and, through its own connecting structure, transport the collected gas to the outdoor unit, thereby realizing the air conditioning system's circulation function. Structurally, the air conditioning manifold typically consists of a main manifold and several branch manifolds.

[0003] Patent document (CN202304128U) discloses an air intake device for a condenser, including an air intake pipe and an air intake manifold, as shown in the accompanying drawings. Figure 1 As can be seen, the intake pipe is located in the main section of the intake manifold and is arranged vertically. It should be noted that when gas flows from the intake pipe into the intake manifold, the gas exerts an impact force on the inner wall of the intake pipe and causes the intake manifold to vibrate. This affects the sealing and connection strength of the condenser's intake device and the external connection. After long-term use, the connection may loosen and leak.

[0004] Therefore, there is a need for an air conditioning manifold assembly with a buffer and adjustable flow rate. Summary of the Invention

The three-way connector has a T-shaped cavity, and a buffer pad and a flow divider are fixedly connected to the cavity wall opposite to the lower outlet. The flow divider allows the gas to flow evenly to both sides, and the buffer pad reduces the vibration generated when the gas impacts the flow divider. Compared with the prior art, it has the advantages of having a buffer and being able to finely adjust the flow rate.

[0006] Another objective of this application is to provide an air conditioning manifold assembly, wherein the middle section of the buffer pad has a first insertion hole and several second insertion holes, the diverter includes a conical portion, an arched portion and a convex post assembly, the convex post assembly includes a first convex post and several second convex posts, the two ends of the arched portion are respectively fixedly connected to the conical portion and the convex post assembly, the first convex post extends into the first insertion hole, the second convex post extends into the second insertion hole, and the convex post assembly is bonded to the buffer pad, the conical portion faces the lower outlet of the tee connector, thereby realizing that the diverter is installed on the buffer pad.

[0029] Schematic illustration of an air conditioning manifold assembly, for reference. Figures 1 to 5 An air conditioning manifold assembly according to a preferred embodiment of the present invention includes a first manifold 10, two second manifolds 20 and a three-way connector 30.

[0030] Specifically, such as Figures 1 to 3 As shown, the lower outlet of the three-way connector 30 is connected to the first gas collecting pipe 10, and the left and right outlets of the three-way connector 30 are respectively connected to the two second gas collecting pipes 20, so that the first gas collecting pipe 10 and the second gas collecting pipe 20 are arranged perpendicularly. The three-way connector 30 has a T-shaped cavity 301, and a buffer pad 40 and a flow divider 50 are fixedly connected to the cavity wall of the T-shaped cavity 301 opposite to the lower outlet.

[0031] It should be noted that the gas flows from the first gas collecting pipe 10 to the two second gas collecting pipes 20. By setting the flow divider 50, the gas flows more evenly to the two second gas collecting pipes 20. By setting the buffer pad 40 between the flow divider 50 and the cavity wall of the T-shaped cavity 301, a buffering effect is provided when the gas flows along the flow divider 50 to the buffer pad 40 and when the gas impacts the flow divider 50, reducing the overall vibration of the second gas collecting pipe 20 caused by the inflow of air. Compared with the prior art, it has the advantages of having a buffer and being able to finely adjust the flow rate.

[0032] Specifically, to achieve a fixed connection between the buffer pad 40 and the tee connector 30, such as Figure 4 As shown, the buffer pad 40 is arched, and the outer side of the buffer pad 40 is bonded to the T-shaped cavity 301 with glue.

[0033] It should be added that, such as Figure 2 As shown, the horizontal section of the T-shaped cavity 301 includes a central tube cavity 3011 and two stepped cavities 3012. The radial dimension of the stepped cavity 3012 is larger than the radial dimension of the central tube cavity 3011. After both second gas collecting pipes 20 extend into the corresponding stepped cavity 3012 and abut against the connecting shoulder surface of the stepped cavity 3012 and the central tube cavity 3011, the second gas collecting pipe 20 and the tee joint 30 are fixedly connected by welding.

[0034] In addition, to facilitate bonding, the overall length of the buffer pad 40 is equal to the length of the central tube 3011. Before the second gas collecting tube 20 is inserted into the stepped cavity 3012, glue is first applied to the outer side of the buffer pad 40. Then, the buffer pad 40 is passed through the stepped cavity 3012 and inserted into the central tube 3011. By pressing the buffer pad 40 and letting it stand for a predetermined time, after the glue has solidified, the buffer pad 40 is bonded to the cavity wall of the central tube 3011.

[0035] Furthermore, to achieve the connection between the diverter 50 and the buffer pad 40, such as... Figure 3 As shown, the middle section of the buffer pad 40 has a first insertion hole 401 and several second insertion holes 402. The diverter 50 includes a conical portion 501, an arched portion 502, and a protrusion assembly. The protrusion assembly includes a first protrusion 503 and several second protrusions 504. The two ends of the arched portion 502 are fixedly connected to the conical portion 501 and the protrusion assembly, respectively. The first protrusion 503 extends into the first insertion hole 401, and the second protrusions 504 extend into the second insertion holes 402. The protrusion assembly is bonded to the buffer pad 40. The conical portion 501 faces the lower outlet of the tee connector 30.

[0036] It should be noted that after applying adhesive to the sidewalls of the first protrusion 503 and the second protrusion 504, the first protrusion 503 is inserted into the first insertion hole 401, and the second protrusion 504 is inserted into the second insertion hole 402, thereby achieving an adhesive connection between the protrusion assembly and the buffer pad 40. In addition, due to the structural characteristics of the conical portion 501, the gas will be divided after contacting the conical portion 501, reducing the impact on the conical portion 501 as a whole. Furthermore, after contacting the conical portion 501, the gas will flow along the conical portion 501 to the inner sidewall of the buffer pad 40, and finally flow to the two second gas collecting pipes 20. In addition, both the first insertion hole 401 and the second insertion hole 402 are through holes.

[0037] Furthermore, to achieve secondary fixation of the diverter 50 and the buffer pad 40, such as... Figure 3 As shown, the T-shaped cavity 301 has a first threaded hole 3013 on the cavity wall opposite to the lower outlet. The air conditioning manifold assembly also includes a swivel column 60, which is threadedly connected to the first threaded hole 3013. The end of the swivel column 60 near the buffer pad 40 is provided with a first magnet 601 and a second magnetic ring 602. The diverter 50 is made of magnetic metal. When the swivel column 60 is screwed into the first threaded hole 3013, the first magnet 601 is directly opposite the first protrusion 503, and the projection of the second magnetic ring 602 on the axial direction of the swivel column 60 covers each of the second protrusions 504.

[0038] It should be noted that after the buffer pad 40 with the diverter 50 is bonded to the cavity wall of the central tube 3011, the swivel post 60 is screwed into the first threaded hole 3013. Then, the first magnet 601 applies a magnetic attraction force to the first protrusion 503, and the second magnetic ring 602 applies a magnetic attraction force to each of the second protrusions 504. As a result, the diverter 50 is further fixed in the corresponding position under the action of magnetic force, and the buffer pad 40 is further fixed to the cavity wall of the central tube 3011 under the pressure of the diverter 50.

[0039] Furthermore, since the second gas collecting pipe 20 may have processing errors during manufacturing, resulting in slight variations in flow rate, in order to achieve slight adjustments in flow rate and balance the outlet flow rate of the two second gas collecting pipes 20, such as... Figure 3As shown, the air conditioning manifold assembly also includes two adjusting columns 70. The rotating column 60 has two second threaded holes, and the diverter 50 has two concealed holes 505. The two adjusting columns 70 are respectively threaded to the two second threaded holes, and the adjusting column 70 passes through the buffer pad 40 and extends into the two concealed holes 505. When the adjusting column 70 is turned, one end of the adjusting column 70 extends out of the opening of the concealed hole 505 by a predetermined distance or is submerged in the concealed hole 505.

[0040] It should be noted that after testing, if the air flow rate of one second gas collecting pipe 20 is slightly greater than that of the other second gas collecting pipe 20, the rotating column 60 at the end with the larger air flow rate is turned and the rotating column 60 is inserted into the opening of the inner hole 505 to provide greater resistance to the airflow and make the overall channel cross-sectional area smaller, thereby achieving a slight adjustment of the gas flow rate.

[0041] In addition, to ensure airtightness, such as Figure 3 As shown, each of the second threaded holes has a sealing plug 80 at the end opposite to the adjusting post 70. It should be noted that when it is necessary to remove the sealing plug 80 and screw on the rotating post 60, the sealing plug 80 can be hooked in with an external hook and pulled out. After screwing on the rotating post 60 and adjusting, the sealing plug 80 can be inserted into the second threaded hole.

[0042] Furthermore, in this application, such as Figure 1 As shown, each of the second gas collecting pipes 20 has a plurality of gas outlet pipes 201 arranged at intervals.

[0043] In addition, such as Figure 5 As shown, each of the two second gas collecting pipes 20 has a curved pipe 202 at one end opposite to the second gas collecting pipe 20, and the curved pipe 202 has a reduced diameter section 2021 at the end opposite to the second gas collecting pipe 20.

[0044] In summary, the air conditioning manifold assembly described in the embodiments of this application is explained, which provides advantages such as having a buffer and adjustable flow rate.
