Description

A new type of air conditioning brass connecting pipe Technical Field

[0001] This utility model relates to the field of air conditioner connection technology, and in particular to a novel air conditioner brass connecting pipe. Background Technology

[0002] Air conditioning connecting pipes are an indispensable part of the air conditioning system. They mainly connect the indoor unit and the outdoor unit, like a bridge. There are usually two pipes: one is a high-pressure pipe and the other is a low-pressure pipe. Refrigerant flows inside these connecting pipes and circulates between the indoor and outdoor units to achieve the cooling or heating function.

[0003] A search revealed that the document with publication number "CN222278736U" mentions "this utility model discloses an air conditioning connection pipe in a factory area, including a pipe body, an operating port on the side wall of the pipe body, a first snap-fit ​​block and a second snap-fit ​​block fixedly assembled in the inner cavity of the pipe body, and snap-fit ​​grooves respectively opened on the side walls of the first snap-fit ​​block and the second snap-fit ​​block, and a rotating plate rotatably connected to the inner cavity of the pipe body, with a snap-fit ​​mechanism assembled in the side wall of the rotating plate." In use, this modification alters the connection pipe between the air conditioning surface cooler and the outside of the factory building by adding a rotating plate that can be adjusted in position within the pipe. This connection pipe can effectively protect the air conditioning surface cooler in winter, further reducing the probability of the air conditioning surface cooler being damaged by freezing and saving on the maintenance costs of the air conditioning surface cooler.

[0004] However, in existing air conditioning systems, brass connecting pipes are an important component connecting indoor and outdoor units. Traditional brass connecting pipes mainly transfer refrigerant through their own pipe structure. However, during use, ordinary brass connecting pipes have poor thermal conductivity or support, which can easily lead to poor cooling or heating performance. They are also easily damaged by external pressure. At the same time, during operation, insufficient sealing at the connection points can easily occur, leading to refrigerant leakage, which increases maintenance costs and safety risks.

[0005] Therefore, we have developed a new type of air conditioning brass connecting pipe to solve the above problems. Summary of the Invention

[0006] To overcome the above shortcomings, this utility model provides a novel air conditioning brass connecting pipe.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A novel air conditioning brass connecting pipe includes an air conditioning connecting brass inner pipe, a heat-conducting layer on the outer side of the air conditioning connecting brass inner pipe, a mesh support layer on the outer side of the heat-conducting layer, and air conditioning pipe connecting assemblies connected to both ends of the air conditioning connecting brass inner pipe. The air conditioning pipe connecting assemblies include pipe heads welded to both ends of the air conditioning connecting brass inner pipe, a spiral flow guiding core on the inner wall of the pipe head, a pressure relief plate on the inner wall of the air conditioning connecting brass inner pipe, a rubber gasket fitted to the outer side of the pipe head, a threaded plug installed on the outer side of the rubber gasket, and a sleeve on the rear side of the threaded plug.

[0009] As a further description of the above technical solution:

[0010] The thermally conductive layer is bonded to the brass inner tube of the air conditioner, and the thermally conductive layer is tightly attached to the brass inner tube of the air conditioner. The thermally conductive layer is made of nano-thermal conductive silicone.

[0011] As a further description of the above technical solution:

[0012] The mesh support layer and the heat-conducting layer are bonded together, and the mesh support layer is a metal wire braided layer.

[0013] As a further description of the above technical solution:

[0014] The spiral guide core is welded to the tube head, and the spiral guide core is arranged around the inner wall of the tube head.

[0015] As a further description of the above technical solution:

[0016] The pressure relief plate is welded to the brass inner tube connecting the air conditioner, and the pressure relief plate is one centimeter away from the tube end.

[0017] As a further description of the above technical solution:

[0018] The threaded plug and the pipe end are connected by a sleeve, and the threaded plug and the pipe end are sealed by a rubber gasket.

[0019] As a further description of the above technical solution:

[0020] The gasket and the tube head are connected by a sleeve, and the gasket is a metal sheet on the outside and a rubber material on the inside.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This utility model, through the heat-conducting layer and the mesh support layer, allows the heat-conducting layer of nano-thermal conductive silicone to quickly and evenly transfer heat when needed, effectively improving the heat exchange efficiency of the air conditioning system and ensuring better cooling or heating effects. The mesh support layer can effectively disperse external pressure, reduce the deformation of the brass inner tube connecting the heat-conducting layer and the air conditioner due to extrusion, and extend the service life.

[0023] 2. This utility model utilizes an air conditioning pipe connection assembly. The spiral guide core optimizes refrigerant flow, transforming it into a spiral flow, reducing flow resistance and enhancing heat exchange efficiency. The pressure relief plate promptly releases excessive pressure within the pipe, preventing pipe bursts, improving safety, and reducing water hammer effects. The threaded plug, in conjunction with the rubber gasket, tightly presses together, reducing gaps and effectively preventing refrigerant leakage. Furthermore, the gasket, through its internal rubber material, and the metal plates at both ends, apply uniform pressure to the pipe head and threaded plug, ensuring a stronger seal at the connection and further preventing refrigerant leakage. The rubber material also possesses a certain degree of resilience, ensuring a consistent sealing effect. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please refer to Figures 1-6. This utility model provides a technical solution: a novel air conditioning brass connecting pipe, including an air conditioning connecting brass inner pipe 1, a heat-conducting layer 2 on the outer side of the air conditioning connecting brass inner pipe 1, a mesh support layer 3 on the outer side of the heat-conducting layer 2, and air conditioning pipe connecting assemblies 4 connected to both ends of the air conditioning connecting brass inner pipe 1. The air conditioning pipe connecting assembly 4 includes pipe heads 401 welded to both ends of the air conditioning connecting brass inner pipe 1, a spiral flow guiding inner core 402 on the inner wall of the pipe head 401, a pressure relief plate 403 on the inner wall of the air conditioning connecting brass inner pipe 1, a rubber gasket 404 sleeved on the outer side of the pipe head 401, a threaded plug 405 installed on the outer side of the rubber gasket 404, and a gasket 406 on the rear side of the threaded plug 405.

[0033] Furthermore, the heat-conducting layer 2 is bonded to the air conditioner connecting brass inner tube 1, and the heat-conducting layer 2 is tightly attached to the air conditioner connecting brass inner tube 1. The heat-conducting layer 2 is made of nano thermally conductive silicone. When needed, the heat-conducting layer 2 of nano thermally conductive silicone can quickly and evenly transfer heat, effectively improving the heat exchange efficiency of the air conditioning system and ensuring better cooling or heating effects.

[0034] Furthermore, the mesh support layer 3 and the heat-conducting layer 2 are bonded together. The mesh support layer 3 is a metal wire braided layer. When needed, the mesh support layer 3 can effectively disperse external pressure, reduce the deformation of the heat-conducting layer 2 and the air-conditioning connecting brass inner tube 1 due to extrusion, and extend the service life.

[0035] Furthermore, the spiral guide core 402 is welded to the tube head 401. The spiral guide core 402 is arranged around the inner wall of the tube head 401. When needed, the spiral guide core 402 can optimize the refrigerant flow, transform the refrigerant flow into a spiral flow, reduce flow resistance and enhance heat exchange efficiency.

[0036] Furthermore, the pressure relief plate 403 is welded to the brass inner tube 1 of the air conditioner connection. The pressure relief plate 403 is one centimeter away from the tube end 401. When needed, the pressure relief plate 403 can release the excessive pressure in the tube in time, prevent the tube from bursting, improve safety, and reduce the water hammer effect.

[0037] Furthermore, the threaded plug 405 and the pipe end 401 are connected by a sleeve, and the threaded plug 405 and the pipe end 401 are sealed by a rubber gasket 404. When needed, the threaded plug 405 and the rubber gasket 404 are tightly pressed together, which can reduce the generation of gaps and thus effectively prevent refrigerant leakage.

[0038] Furthermore, the gasket 406 and the pipe head 401 are connected by a sleeve. The gasket 406 has a metal sheet on the outside and a rubber material on the inside. When needed, the gasket 406, through the inner rubber material, and the metal sheets at both ends, will apply uniform pressure to the pipe head 401 and the threaded plug 405 to ensure a stronger seal at the connection and further prevent refrigerant leakage. The rubber material has a certain degree of resilience to ensure the sealing effect.

[0039] Working principle: When needed, the threaded plug 405 on the outside of the pipe head 401 is tightened onto the air conditioner. A rubber gasket 404 seals the inside of the threaded plug 405, and a gasket 406 provides fixed pressure on the outside. During use, the refrigerant flows through the air conditioner connecting brass inner pipe 1. The outer heat-conducting layer 2 and mesh support layer 3 provide protection. When the refrigerant flows between the pipe heads 401, a pressure relief plate 403 provides protection. When it flows into the pipe head 401, a spiral guide core 402 guides it to form a spiral flow, reducing resistance, enhancing heat exchange, and ensuring efficient refrigerant circulation. This completes the usage process of a new type of air conditioner brass connecting pipe.
