[0040] In related technologies, the main pipe and branch pipes in a pipeline system are usually circular. Since the wall of the circular main pipe is annular, when the connector of the branch pipe is connected (e.g., welded) to the wall of the circular main pipe, the end face of the branch pipe connector and the wall of the circular main pipe are difficult to fit together. The branch pipe connector is easy to slip off, making the connection operation inconvenient. Moreover, after the connection, the fluid is prone to leak from the connection between the branch pipe connector and the main pipe, resulting in low connection reliability.

[0041] In view of this, the present disclosure provides a fluid pipeline in which the main pipe and branch pipe joints can fit together, which facilitates connection, reduces connection difficulty and ensures connection reliability.

[0042] It is worth noting that the fluid conduit described in this disclosure is intended for the flow of fluids. The fluid is a flowable medium, including liquids and / or gases, such as coolants, thereby enabling the fluid conduit to be used as a liquid-cooled conduit. However, it is understood that the application scope of the fluid conduit described in this disclosure includes, but is not limited to, flowing other flowable media.

[0043] Figure 1 This is a schematic diagram of the structure of the fluid pipeline according to the first embodiment of this disclosure. Figure 2 This is a cross-sectional view of a fluid pipeline according to the first embodiment of this disclosure.

[0044] An embodiment of the present disclosure provides a fluid pipeline including a main pipe body 11 and a plurality of branch pipe joints 12. The main pipe body 11 has a flat pipe surface 111 extending axially.

[0045] Figure 3 This is a cross-sectional schematic diagram of the fluid pipeline according to the first embodiment of this disclosure from another cutting perspective. (See also...) Figure 3 The cross-sectional shape of the main tube 11 can be rectangular, such as square, and the outer peripheral surface of the rectangular main tube 11 can form the flat tube surface 111.

[0046] Figure 4 This is a schematic diagram of the structure of a fluid pipeline according to the second embodiment of this disclosure. Figure 5 This is a cross-sectional schematic diagram of a fluid pipeline according to a second embodiment of this disclosure, viewed from a cutting angle. (See also...) Figure 4 and Figure 5 The cross-sectional shape of the main body 11 can be D-shaped. The outer peripheral surface of the D-shaped main body 11 can form the flat pipe surface 111. The arc surface of the D-shaped pipe is also easy to adapt to the original application scenario of the round pipe, such as the application scenario where the round pipe is fitted and fixed in the arc groove, which improves the adaptability of the original scenario compared to the square pipe.

[0047] Optionally, the main body 11 is a plastic component, made of plastic material or modified reinforced plastic material. As an example, the plastic material includes one or more of polyolefin materials (PE, PP-type polyolefins), nylon materials, polyphenylene sulfide (PPS), and fluoroplastics (PVDF, ETFE, PTFE, etc.). The modified reinforced plastic material has a plastic matrix doped with reinforcing modifiers to enhance the properties of the plastic matrix, wherein the plastic matrix includes one or more of polyolefin materials (PE, PP-type polyolefins), nylon materials, polyphenylene sulfide (PPS), and fluoroplastics (PVDF, ETFE, PTFE, etc.). The reinforcing modifiers include one or more of glass fiber (GF), carbon fiber (CF), and mineral powder (MD).

[0048] It should be understood that when the main pipe 11 is used to circulate coolant as a liquid cooling pipeline, the metal pipeline not only increases the weight of the liquid cooling pipeline and the manufacturing cost, but also makes it prone to electrochemical corrosion due to long-term contact with the coolant, leading to the precipitation of metal ions, contamination of the coolant, and reduction of the coolant's heat dissipation efficiency. Therefore, the main pipe 11 of this disclosure is made of plastic, which is lightweight, has good corrosion resistance, and the circulating fluid is not easily contaminated.

[0049] Optionally, the main body 11 can be formed by injection molding, extrusion (including single-layer and multi-layer co-extrusion) or blow molding (including multi-layer) using the plastic material or the modified reinforced plastic material.

[0050] See Figure 1 and Figure 2 Multiple branch pipe joints 12 are spaced apart along the axial direction on the flat pipe surface 111. Each branch pipe joint 12 is provided with a branch connection hole that communicates with the main pipe body 11 and is used to connect to a branch pipe body.

[0051] Optionally, the main pipe 11 is provided with an inlet and a plurality of outlets located on the flat pipe surface 111. Each of the outlets is connected to a plurality of branch pipe joints 12 in a one-to-one correspondence. Thus, fluid entering the main pipe 11 from the inlet can be distributed to the plurality of branch pipe joints 12 via the outlets, forming a fluid distribution pipeline. For example, when the fluid is coolant, the coolant entering the main pipe 11 can be distributed to multiple branch pipes via the branch pipe joints 12 to cool multiple devices to be cooled. Of course, it is understood that the inlet can also be used as an outlet, and the multiple outlets can also be used as multiple inlets, allowing fluid to flow into the main pipe 11 via the branch pipe joints 12 and then converge within the main pipe 11, forming a fluid collection pipeline.

[0052] The branch pipe connector 12 has a flat end face 122 that fits against and is connected to the flat pipe surface 111. Therefore, when multiple branch pipe connectors 12 are installed on the main pipe body 11, the flat end face 122 of the flat support fits tightly against the flat pipe surface 111, making it easy to connect the branch pipe connector 12 to the main pipe body 11. Furthermore, after connection, fluid is less likely to leak from the connection between the flat end face 122 and the flat pipe surface 111, resulting in high reliability after connection.

[0053] As an example, the flat end face 122 and the flat pipe face 111 are welded together. The welding connection includes laser welding, ultrasonic welding, hot melt welding, or infrared welding. However, it is understood that the connection method between the flat end face 122 and the flat pipe face 111 in this disclosure includes, but is not limited to, welding; other connection methods may also be used, such as secondary injection molding connection, bonding with adhesive, etc.

[0054] Optionally, the branch pipe connector 12 may be implemented as a plastic part, made of the aforementioned plastic material and modified reinforced plastic material.

[0055] Optionally, the branch pipe joint 12 extends radially outward to form an annular flat seat 121 for tight fitting, the bottom surface of the annular flat seat 121 being the flat end face 122 and welded to the flat pipe face 111.

[0056] It is also worth mentioning that the branch pipe joint 12 and the branch pipe body connected thereto can be integrally formed, with the branch pipe joint 12 integrally formed at the end of the branch pipe body, or the branch pipe joint 12 and the branch pipe body connected thereto can be separately connected, with the branch pipe joint 12 detachably connected to the end of the branch pipe body.

[0057] Optionally, the fluid pipeline further includes a branch connection pipe 13. The branch connection pipe 13 is fixed within the branch connection hole. The branch connection pipe 13 is threaded to the branch pipe body, and its strength is greater than that of the branch pipe joint 12. Therefore, when the branch pipe body is threaded to the branch connection pipe 13, due to the greater strength and deformation resistance of the branch connection pipe 13, the branch pipe body can be relatively fully and tightly threaded inside the branch connection pipe 13.

[0058] As an example, the branch pipe connector 12 is a first plastic component, and the branch connecting pipe 13 is a first metal component with greater strength than the first plastic component. For example, the branch pipe connector 12 is made of the aforementioned plastic material or modified plastic material. The branch connecting pipe 13 is made of stainless steel or aluminum alloy. Therefore, the branch pipe connector 12 has strong corrosion resistance and is lightweight. The branch connecting pipe 13 has high strength and strong resistance to deformation. Thus, the branch connection structure composed of the branch pipe connector 12 and the branch connecting pipe 13 not only has strong corrosion resistance and is lightweight, but also has strong resistance to deformation when tightened by the branch pipe thread, which helps to ensure that the branch pipe can be relatively fully tightened in the branch connection structure, ensuring the connection firmness and reliability of the branch pipe connection.

[0059] Of course, it is understood that the materials of the branch pipe joint 12 and the branch connection pipe 13 disclosed herein include, but are not limited to, those described above. The branch pipe joint 12 and the branch connection pipe 13 may also be plastic parts and integrally injection molded or connected by secondary injection molding.

[0060] Specifically, the branch connection pipe 13 is injection molded to the branch pipe connector 12, which is formed on the outside of the metal branch connection pipe 13. The branch pipe connector 12 and the branch connection pipe 13 are connected together with a tongue-and-groove fit, resulting in high connection strength and high sealing performance.

[0061] Optionally, an annular seal 14 is provided between the branch pipe joint 12 and the branch connecting pipe 13 to seal the connection between the branch pipe joint 12 and the branch connecting pipe 13, ensuring the sealing performance between them. As an example, the annular seal 14 can be a sealing ring.

[0062] Optionally, the fluid pipeline further includes a pressure relief pipe connector 15. The pressure relief pipe connector 15 is connected to one end of the main pipe body 11 and has a pressure relief connection hole that communicates with the main pipe body 11 and is used to connect an openable and closable pressure relief pipeline.

[0063] Therefore, during the flow of fluid through the main pipe 11, when the internal pressure of the main pipe 11 is too high, the pressure relief pipe opens, allowing the internal pressure of the main pipe 11 to be discharged to the outside through the pressure relief pipe joint 15 and the pressure relief pipe, thereby reducing the internal pressure of the main pipe 11 and ensuring the safety of the main pipe 11. When the internal pressure of the main pipe 11 is low or within the normal range, the pressure relief pipe closes, allowing the fluid inside the main pipe 11 to continue flowing between the branch pipe joint 12 and the main pipe 11, ensuring normal fluid flow.

[0064] As an example, when the fluid is a liquid, such as coolant, the pressure relief pipeline may include a pressure relief valve 17, which is used to open when the pressure in the main pipe 11 is too high, thereby allowing the gas carried in the coolant flowing through the main pipe 11 to be discharged through the pressure relief pipe joint 15 and the pressure relief valve 17, thus ensuring the operational safety of the fluid pipeline. When the pressure in the main pipe 11 is low and within the normal range, the pressure relief valve 17 remains closed, so that the pressure relief pipe joint 15 is disconnected from the outside, thereby allowing the coolant to continue to flow normally between the main pipe 11 and the branch pipe joint 12.

[0065] Optionally, the pressure relief pipe joint 15 further includes a pressure relief connecting pipe 16. The pressure relief connecting pipe 16 is fixed inside the pressure relief connecting hole, and the pressure relief connecting pipe 16 provides a threaded connection to an openable and closable pressure relief pipeline and has a strength greater than that of the pressure relief pipe joint 15. Therefore, when the pressure relief pipeline is threadedly connected to the pressure relief connecting pipe 16, due to the greater strength and stronger resistance to deformation of the pressure relief connecting pipe 16, the pressure relief pipeline can be relatively fully and properly threaded inside the pressure relief connecting pipe 16.

[0066] As an example, the pressure relief pipe connector 15 is a second plastic component, and the pressure relief connecting pipe 16 is a second metal component with greater strength than the second plastic component. For example, the pressure relief pipe connector 15 is made of the aforementioned plastic material or modified plastic material. The pressure relief connecting pipe 16 is made of stainless steel or aluminum alloy. Therefore, the pressure relief pipe connector 15 has strong corrosion resistance and is lightweight. The pressure relief connecting pipe 16 has high strength and strong resistance to deformation. Thus, the pressure relief pipe connector 15 not only has strong corrosion resistance and is lightweight, but also has strong resistance to deformation when tightened by the threads of the pressure relief pipe, allowing the pressure relief pipe to be tightened relatively sufficiently, resulting in strong connection strength and reliability.

[0067] Of course, it is understood that the materials of the pressure relief pipe joint 15 and the pressure relief connecting pipe 16 disclosed herein include, but are not limited to, those described above. The pressure relief pipe joint 15 and the pressure relief connecting pipe 16 may also be plastic parts and integrally injection molded or connected by secondary injection molding.

[0068] Specifically, the pressure relief connecting pipe 16 is injection molded to the pressure relief pipe connector 15, which is injection molded onto the outside of the metal pressure relief connecting pipe 16. Furthermore, the pressure relief pipe connector 15 and the pressure relief connecting pipe 16 are connected together with a tongue-and-groove fit, resulting in high connection strength and high sealing performance.

[0069] Optionally, the fluid conduit further includes an adapter 18. The adapter 18 is connected to the other end of the main pipe 11 and is used to connect to an external pipe so that fluid flows into or out of the main pipe 11 via the external pipe.

[0070] Optionally, the adapter 18 has an annular recess, and the main body 11 is connected inside the annular recess. Specifically, see [reference needed]. Figure 2 The annular recess can be implemented as an annular groove 181, and the adapter 18 is inserted into the annular groove 181 and welded to the main body 11.

[0071] Figure 6 This is a cross-sectional schematic diagram of the fluid pipeline according to the second embodiment of this disclosure from another cutting perspective. See also... Figure 6The annular recess can be implemented as an annular platform 182, and the main body 11 is prepositioned to abut against the annular bottom wall of the annular platform 182 and welded to the main body 11. The connection between the adapter 18 and the main body 11 is convenient and firm.

[0072] Optionally, the adapter 18 extends in a bend to connect the main pipe 11 to an external pipe. As an example, the external pipe is arranged perpendicularly to the main pipe 11, and the bend angle of the adapter 18 is 90° to connect the mutually perpendicular external pipe and the main pipe 11. Of course, it is understood that when the arrangement and angle of the external pipe relative to the main pipe 11 are different, the bend angle of the adapter 18 can also be different. The adapter 18 can also extend without a bend to connect the main pipe 11 and the external pipe extending in the same direction. The bend angle of the adapter 18 can be appropriately selected between 0° and 180°.

[0073] Optionally, the adapter 18 is an injection molded part, integrally injection molded.

[0074] Optionally, the portion of the adapter 18 used to connect to the external pipe has a bamboo joint structure, which is used to connect with the external pipe through bamboo joints, thereby improving the connection strength.

[0075] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the protection scope of this disclosure.
