Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange systems, in particular to an air-conditioning pipeline connection structure and an air-conditioning system. Background Art

[0002] In an air-conditioning system, a valve body is used to control the flow of a medium to achieve the switching between refrigeration and heating. The valve body is connected to other structures through pipes, and the material of the pipe assembly is often copper. Copper metal has good heat exchange performance, corrosion resistance, compressive strength, resistance to high and low temperatures, is easy to weld and has a long service life, and is very suitable as the material of the pipe assembly for the air-conditioning system.

[0003] Since the price of copper material is increasing day by day, which is not conducive to the lightweight design and cost control of air-conditioning products, the lightweight and cost-reducing design of air-conditioning pipelines has become the mainstream in the industry, and various pipe assemblies made of aluminum and stainless steel materials have gradually emerged.

[0004] During the welding process of the pipe assembly and other structures, the number of pipe assemblies is often multiple, and multiple pipe assemblies are concentrated. The distance between the non-copper pipe assembly and the welding torch is relatively close, and the heat generated by the welding torch easily oxidizes the non-copper pipe assembly, resulting in poor appearance. To solve the problem of poor appearance, it is necessary to improve the accuracy of the movement of the welding torch, which will affect the production efficiency, resulting in the inability to comprehensively promote most of the current technical solutions to replace copper pipes.

[0033] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0034] The embodiment of the present application provides an air-conditioning pipe connection structure and an air-conditioning system. The air-conditioning pipe connection structure can effectively improve the welding efficiency with other structures. The following is a specific description in conjunction with the accompanying drawings.

[0035] Please refer to Figure 1 and Figure 2 , Figure 1 This is the first schematic structural diagram of the air-conditioning pipe connection structure provided by the embodiment of the present application, Figure 2 is Figure 1 an exploded schematic diagram of

[0036] The present application provides an air-conditioning pipe connection structure 10, including a valve body 11 and a plurality of pipe assemblies 12.

[0037] The valve body 11 can also be called a reversing valve. The valve body 11 is used to control the flow of the medium, realize the switching between refrigeration and heating, and can also be used for defrosting. The valve body 11 can be a two-way valve, a four-way valve or a multi-way valve, etc. In the embodiment of the present application, the valve body 11 is taken as an example of a four-way valve.

[0038] Please refer to Figure 3 , Figure 3 This is a schematic structural diagram of the valve body provided by the embodiment of the present application. The valve body 11 includes a valve body main body 111 and a plurality of connecting pipes 112. The valve body main body 111 is connected to the plurality of connecting pipes 112 and is internally connected to the valve body main body 111. An element for controlling the connection state of the connecting pipes 112 is provided inside the valve body main body 111. The plurality of connecting pipes 112 correspond to the plurality of pipe assemblies 12 one by one, and each connecting pipe 112 is connected to one pipe assembly 12. It can be understood that the number of the connecting pipes 112 and the pipe assemblies 12 can be 4. One end of the pipe assembly 12 is connected to the connecting pipe 112, and the other end is welded to other structures.

[0039] The material of the valve body 11 can be all copper, all stainless steel or a semi-stainless steel structure. When the valve body 11 is of a semi-stainless steel structure, the material of the valve body main body 111 is stainless steel, and the material of the plurality of connecting pipes 112 is copper.

[0040] A plurality of pipe assemblies 12 are connected to the valve body 11. One end of each pipe assembly 12 away from the valve body 11 is a welding end 120, and the welding end 120 is used for welding with other structures. Different pipe assemblies 12 have different types. For example, it is a uniform one-piece pipe, a combined pipe with different materials for each section, or a functional pipe with a muffler provided in the middle. The pipe assembly 12 in the embodiment of the present application can be of a single type, or multiple pipe assemblies 12 can be arranged in combination. The type selection of the pipe assembly 12 can be set according to the actual situation, and the embodiment of the present application does not limit this.

[0041] Please refer to Figure 4 , Figure 4 which is the second structural schematic diagram of the air-conditioning pipeline connection structure provided by the embodiment of the present application. The air-conditioning pipeline connection structure 10 can be divided into a plurality of regions 13, and the plurality of regions 13 can include a welding region 131 and a non-welding region that are connected to each other. At least two welding ends 120 are located in the welding region 131. It can be understood that the welding region 131 can be the region where the heating end of the welding torch moves, and the welding torch can sequentially weld the welding ends 120 in the welding region 131. Further, the minimum area division of the welding region 131 can be the set (union) of the radiation areas of the thermal radiation that can affect metals (stainless steel or aluminum) of non-copper materials during the process of the heating end of the welding torch sequentially welding a plurality of welding ends 120 according to the shortest distance. In some cases, the area of the welding region 131 can be further enlarged to facilitate preparation, assembly and improve the error tolerance rate. The other regions of the air-conditioning pipeline connection structure 10 except the welding region 131 are non-welding regions.

[0042] At least two welding ends 120 are located in the welding region 131. In some cases, the number of welding ends 120 located in the welding region 131 can be three or four.

[0043] The materials of the pipe assembly and the part of the valve body corresponding to the welding region 131 are copper. When the welding torch welds the welding ends 120 in the welding region 131, the materials of the structures in the welding region 131 are all copper, and there are no structures of non-copper materials. The heat generated by the welding torch will not cause the non-copper material pipe assembly to oxidize and cause poor appearance. The movement accuracy of the welding torch in the welding region 131 can be reduced, and the error tolerance rate of the overall welding process is increased, thereby improving the production efficiency.

[0044] For example, in the height direction of the air-conditioning pipeline connection structure 10, the volume where the air-conditioning pipeline connection structure 10 is located is divided into two or three regions 13, or in the width direction of the air-conditioning pipeline connection structure 10, the volume where the air-conditioning pipeline connection structure 10 is located is divided into two or three regions 13. One of the regions 13 is the welding area 131, and the other regions 13 are non-welding areas. In the embodiments of the present application, the division of the regions 13 is not limited.

[0045] As Figure 4 shown, for another example, the overall region of the air-conditioning pipeline connection structure 10 is a triangular region. The triangular region is divided to divide the triangular region into a first non-welding area, a welding area 131, and a second non-welding area. At least two welding ends 120 of the pipe assembly 12 are located in the welding area 131.

[0046] When using a welding torch to weld the pipe assembly 12 in the welding area 131 to other structures, the heating end of the welding torch only needs to move within the welding area 131 to successively weld multiple pipe assemblies 12 to other structures, avoiding affecting other structures made of non-copper materials.

[0047] The materials of the valve body 11 and the pipe assembly 12 can be copper or stainless steel. It can be understood that although the air-conditioning pipeline connection structure 10 made of copper has the advantages of good thermal conductivity, easy welding, and no welds, etc., the air-conditioning pipeline connection structure 10 made of copper is expensive, making the overall production cost of the air-conditioning system 100 remain high. The cost of the structure made of stainless steel is lower. Therefore, when part of the structure of the air-conditioning pipeline connection structure 10 in the present application is made of copper and the other part is made of stainless steel, compared with the air-conditioning pipeline connection structure 10 made entirely of copper, the cost is lower on the premise of ensuring the welding effect.

[0048] It can be understood that if part of the structure of the valve body 11 is located in the welding area 131, then part of the structure of the valve body 11 is copper; if part of the structure of the pipe assembly 12 is located in the welding area 131, then part of the structure of the pipe assembly 12 is copper. It can be understood that the materials of part of the valve body 11 and / or the pipe assembly 12 located in the non-welding area can be copper or stainless steel.

[0049] It can be understood that since stainless steel is an alloy structure and the melting points are inconsistent, oxidation may occur under high-temperature action, generating oxides, which will affect its appearance and performance (strength, hardness). Therefore, in the embodiments of the present application, in the welding process, the heating end of the welding torch only needs to be aligned with the welding end 120 in the welding area 131 for heating, and the materials of the other structures in the welding area 131 are all copper to avoid the heat generated by the welding torch affecting other parts of the air-conditioning pipeline connection structure 10 made of stainless steel.

[0050] The pipe assembly 12 can be a straight pipe or a bent pipe, which is specifically set according to the actual installation space and usage requirements. By changing the position of the welding end 120 and the materials of the valve body 11 and / or the pipe assembly 12 corresponding to the welding area 131, when the welding end 120 is welded to other structures, the materials of the valve body 11 and / or the pipe assembly 12 near the welding end 120 are all copper, thereby improving the welding reliability and reducing costs.

[0051] In the above embodiment, there are various situations for the structures and materials of the valve body 11 and the pipe assembly 12, which will be further described below.

[0052] Please continue to refer to Figure 1 、 Figure 2 and Figure 5 , Figure 5 which is a schematic structural diagram of the first pipe assembly provided by the embodiment of the present application. The pipe assembly 12 includes a first pipe assembly 121, and the first pipe assembly 121 includes a first pipe 1211, a silencer 1212, a second pipe 1213, and a third pipe 1214 that are connected in sequence. The material of the first pipe 1211 is copper, and one end of the first pipe 1211 away from the silencer 1212 is the welding end 120, and one end of the third pipe 1214 away from the second pipe 1213 is connected to the connecting pipe 112 of the valve body 11.

[0053] At least part of the structure of the first pipe 1211 can be located in the welding area 131. It can be understood that one end of the first pipe 1211 away from the silencer 1212 is the welding end 120, that is, it is welded to other structures. The materials of other structures are often copper, so the material of the welding end 120 is copper, which is convenient for welding.

[0054] In some cases, the material of the silencer 1212 can be stainless steel, and the silencer 1212 is used to reduce the noise generated by the airflow tremor inside the pipeline. The silencer 1212 can be a non-welding area.

[0055] Please refer to Figure 6 , Figure 6 which is a schematic structural diagram of the silencing pipe and the first copper sleeve provided by the embodiment of the present application. The first pipe assembly 121 further includes a first copper sleeve 1215, the first copper sleeve 1215 is fixed on the silencer 1212, and the first pipe 1211 is welded and fixed to the first copper sleeve 1215.

[0056] The first copper sleeve 1215 can be made of red copper material. The first copper sleeve 1215 can be arranged on the inner wall of the port of the muffler 1212 and connected to the port of the muffler 1212 in an inserted manner, as long as the sealed connection between the first copper sleeve 1215 and the port of the muffler 1212 can be achieved. Since the material of the first pipe 1211 is copper and the material of this first copper sleeve 1215 is also copper, it is not easy to have problems such as missed welding or cracks after the two are welded.

[0057] Among them, please refer to Figure 7 , Figure 7 which is the structural schematic diagram of the second pipe provided by the embodiment of the present application. The material of the second pipe 1213 is stainless steel, and the second pipe 1213 can be not located in the welding area 131, that is, located in the non-welding area. Since the muffler 1212 is also made of stainless steel, a copper sleeve structure is not provided at the connection between the second pipe 1213 and the muffler 1212. The materials of the muffler 1212 and the second pipe 1213 are the same, which can effectively improve the connection sealing performance.

[0058] It can be seen from the above embodiments that when connecting structures with different materials, for example, when connecting a structure made of stainless steel and a structure made of copper, by fixedly connecting a copper sleeve on the structure made of stainless steel, and then welding and fixing the copper sleeve to the structure made of copper, the reliability of the connection between the structure made of stainless steel and the structure made of copper is improved.

[0059] Among them, the material of the third pipe 1214 can be copper, and at least part of the structure of the third pipe 1214 can be located in the welding area 131.

[0060] One end of the third pipe 1214 is connected to the second pipe 1213, and the other end is used to connect to other structures. The same as the above embodiments, please continue to refer to Figure 7 , a copper sleeve 1213a is fixedly connected to one end of the second pipe 1213 close to the third pipe 1214, and then the copper sleeve 1213a is connected to the third pipe 1214 to improve the connection reliability, which will not be elaborated here.

[0061] For the case where the first pipe assembly 121 in the embodiment of the present application is connected to other structures, the welding end 120 in the first pipe assembly 121 can be used to weld with other structures, and the other structures can be the low-pressure stop valve 20 and the exhaust port of the compressor 30.

[0062] It is worth noting that when the first piping assembly 121 is connected to different other structures, the mufflers 1212 can be different or the same. When the mufflers 1212 are different, they are recorded as the first muffler 1212 and the second muffler 1212. The first muffler 1212 and the second muffler 1212 mainly differ in length, diameter, and insertion hole diameter. Of course, the situation where the first muffler 1212 and the second muffler 1212 have the same structure is also within the protection scope of this application.

[0063] In some embodiments, see Figure 8 as well as Figure 9 , Figure 8 This is a schematic diagram of the structure of the second piping assembly provided in an embodiment of the present application. Figure 9 The second structural schematic diagram of the second piping assembly provided in the embodiment of the present application is as follows: The piping assembly 12 includes a second piping assembly 122 , and the welding end 120 in the second piping assembly 122 can be used for welding with other structures, and the other structures can be the return air port of the compressor 30 .

[0064] The second pipe assembly 122 may be a split structure, such as Figure 8 ; It can also be an integrated structure, such as Figure 9 .

[0065] Please continue reading Figure 8 When the second piping assembly 122 is a split structure, the second piping assembly 122 includes a fourth pipe 1221, a fifth pipe 1222 and a sixth pipe 1223 connected in sequence, and the end of the sixth pipe 1223 away from the fifth pipe 1222 is connected to the connecting pipe 112 of the valve body 11; the fourth pipe 1221 is made of copper, and the end of the fourth pipe 1221 away from the fifth pipe 1222 is a welding end 120.

[0066] Similar to the above embodiment, at least part of the structure of the fourth pipe 1221 can be located in the welding area 131. It can be understood that the end of the fourth pipe 1221 away from the muffler 1212 is a welding end 120, that is, it is welded with other structures. The material of other structures is often copper, so the material of the welding end 120 is copper, which is convenient for welding.

[0067] The sixth pipe 1223 may be made of copper. At least a portion of the sixth pipe 1223 may be located in the welding area 131 .

[0068] See also Figure 10 , Figure 10Schematic diagram of the structure of the fifth pipe provided by the embodiment of the present application. The material of the fifth pipe 1222 can be stainless steel and may not be located within the welding area 131, that is, it is located within the non-welding area. One end of the fifth pipe 1222 is connected to the fourth pipe 1221, and the other end is connected to the sixth pipe 1223. Similar to the above embodiment, since the materials of the fourth pipe 1221 and the sixth pipe 1223 are both copper, third copper sleeves 1222a and fourth copper sleeves 1222b are respectively provided at both ends of the fifth pipe 1222 and then connected to the fourth pipe 1221 and the sixth pipe 1223 respectively to improve the connection reliability, which will not be elaborated here.

[0069] It can be understood that the second pipe assembly 122 adopts a split structure, and the material of a part of the structure is stainless steel, which can correspondingly reduce the cost.

[0070] Please continue to refer to Figure 8 and Figure 9 When the second pipe assembly 122 is an integral structure, the fourth pipe 1221, the fifth pipe 1222, and the sixth pipe 1223 are integrally formed structures, and the materials of the fourth pipe 1221, the fifth pipe 1222, and the sixth pipe 1223 are the same, and the materials of the fourth pipe 1221, the fifth pipe 1222, and the sixth pipe 1223 are copper. It can be understood that due to the integral structure, the airtightness of the second pipe assembly 122 is better.

[0071] In some embodiments, please refer to Figure 11 , Figure 11 Schematic diagram of the structure of the third pipe assembly provided by the embodiment of the present application. The air-conditioning pipe connection structure 10 includes a third pipe assembly 123. At least part of the structure of the third pipe assembly 123 can be located within the welding area 131 or may not be located within the welding area 131. The welding end 120 in the third pipe assembly 123 can be used for welding with other structures, and the other structure can be the condenser 40.

[0072] The third pipe assembly 123 includes an integrally formed seventh pipe 1231, and the material of the seventh pipe 1231 is copper or stainless steel. The seventh pipe 1231 is connected to the four-way valve, and the end of the seventh pipe 1231 away from the valve body 11 is the welding end 120.

[0073] It can be understood that when the material of the seventh pipe 1231 is copper, the connection stability between the seventh pipe 1231 and the structures with copper materials such as the valve body 11 and other structures is better. When the material of the seventh pipe 1231 is copper, the cost is lower.

[0074] In some embodiments, when the material of the seventh pipe 1231 is stainless steel, the third pipe assembly 123 further includes a second copper sleeve 1232. The seventh pipe 1231 is connected to the connection pipe 112. One end of the seventh pipe 1231 away from the connection pipe 112 is a welding end 120, and the welding end 120 of the seventh pipe 1231 is fixedly connected to the second copper sleeve 1232. Since the materials of other structures are often copper, the second copper sleeve 1232 is provided at the welding end 120 to improve the connection reliability, which will not be elaborated here.

[0075] Please refer to Figure 12 , Figure 12 which is a schematic structural diagram of the television system provided by the embodiment of the present application. The present application also provides an air conditioning system 100, including the above-mentioned air conditioning pipe connection structure 10. The air conditioning system 100 may include an indoor unit and an outdoor unit of the air conditioner. The embodiment of the present application takes the outdoor unit of the air conditioner as an example.

[0076] The air conditioning system 100 further includes a low-pressure cut-off valve 20, a compressor 30, and a condenser 40. The valve body 11 can be respectively connected to the low-pressure cut-off valve 20, the exhaust port of the compressor 30, the suction port of the compressor 30, and the condenser 40.

[0077] Specifically, the air conditioning pipe connection structure 10 in the air conditioning system 100 includes a valve body 11 and four pipe assemblies 12. The four pipe assemblies 12 include two first pipe assemblies 121, one second pipe assembly 122, and one third pipe assembly 123. One of the first pipe assemblies 121 is connected to the low-pressure cut-off valve 20, the other first pipe assembly 121 is connected to the exhaust port of the compressor 30, the second pipe assembly 122 is connected to the suction port of the compressor 30, and the other third pipe assembly 123 is connected to the condenser 40.

[0078] The air conditioning system 100 further includes a housing (not shown in the figure), a motor bracket 61, a motor 62, a fan blade 70, and a chassis component 80. The housing has a receiving cavity, and the motor bracket 61, the motor 62, the fan blade 70, the chassis component 80, the low-pressure cut-off valve 20, the compressor 30, the condenser 40, and the air conditioning pipe connection structure 10 are arranged in the receiving cavity. The chassis component 80 is arranged at the bottom of the receiving cavity.

[0079] The air conditioning system 100 further includes a middle partition plate 90 which is disposed in the accommodation cavity. The condenser 40 and the motor bracket 61 together divide the accommodation cavity into a first accommodation space 51 and a second accommodation space 52. The motor bracket 61, the motor 62, and the blower 70 are disposed in the first accommodation space 51. The motor bracket 61 is fixed to the condenser 40 and is used for fixing the motor 62. The blower 70 is connected to the motor 62 to drive the blower 70 to rotate. The low-pressure cut-off valve 20, the compressor 30, and the air conditioning pipeline connection structure 10 are disposed in the second accommodation space 52.

[0080] The air conditioning pipeline connection structure 10 and the air conditioning system 100 provided by the embodiments of the present application. The air conditioning pipeline connection structure 10 includes a valve body 11 and a plurality of pipe components 12. The plurality of pipe components 12 are connected to the valve body 11, and one end of each pipe component 12 away from the valve body 11 is a welding end 120. Wherein, the air conditioning pipeline connection structure 10 is divided into a connected welding area 131 and a non-welding area, and at least two welding ends 120 are located in the welding area 131. The materials of the corresponding parts of the pipe component 12 and the valve body 11 in the welding area 131 are copper. When the welding torch welds the welding end 120 in the welding area 131, the materials of the structures in the welding area 131 are all copper, and there is no structure made of non-copper material. The heat generated by the welding torch will not cause oxidation of the non-copper material pipe component 12 resulting in poor appearance. The accuracy of the movement of the welding torch in the welding area 131 can be decreased, and the error tolerance of the overall welding process is increased, thereby improving the production efficiency.
