DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The core of the present invention is to provide a piping device that is easy to assemble and disassemble. Another core of the present invention is to provide a heat exchange device including the piping device, wherein the piping device is easy to assemble and disassemble.

[0037] Please refer to Figure 1 An embodiment of the utility model provides a pipeline device, including a main line 1, a liquid inlet pipe 2, a liquid outlet pipe 3 and a hose 4, the liquid inlet pipe 2 and the liquid outlet pipe 3 are respectively connected to the main line 1, the liquid inlet pipe 2 is provided with a first interface 21 for connecting to a power device; the liquid outlet pipe 3 is provided with a second interface 31 for connecting to a target device; the hose 4 is provided at at least one of the preset positions, wherein the preset positions include: between the liquid inlet pipe 2 and the main line 1, between the liquid inlet pipe 2, the liquid outlet pipe 3 and the main line 1, and the liquid outlet pipe 3; the main line 1, the liquid inlet pipe 2 and the liquid outlet pipe 3 form an integrated structure.

[0038] It should be noted that the pipeline device can be used between the power device and the target device, allowing the power device to transport fluid to the target device through the pipeline device. For example, the power device can transport low-temperature liquid from a heat exchanger to the target device through the pipeline device to facilitate cooling the target device. Of course, in other embodiments, based on specific needs, the power device can also transport high-temperature liquid from a heat exchanger to the target device through the pipeline device.

[0039] It can be understood that the main line 1 connects the liquid inlet pipe 2 and the liquid outlet pipe 3. The existence of the main line 1 facilitates the connection between the liquid inlet pipe 2 and the liquid outlet pipe 3 and facilitates the reasonable layout of the liquid inlet pipe 2 and the liquid outlet pipe 3. When the number of the liquid inlet pipes 2 is at least two, the main line 1 also has the function of collecting the fluids of each liquid inlet pipe 2, so that the fluids in each liquid inlet pipe 2 flow out through the liquid outlet pipe 3 after being collected in the main line 1. The main line 1, the liquid inlet pipe 2 and the liquid outlet pipe 3 form an integrated structure, that is, the pipeline device is an integrated pipeline. In this way, there is no need to independently disassemble and assemble the main line 1, the liquid inlet pipe 2 and the liquid outlet pipe 3, which facilitates the overall disassembly and assembly of the pipeline device, bringing many conveniences to the installation and maintenance of the pipeline device; moreover, this structure can avoid the hidden dangers of leakage caused by improper installation and connection when the main line 1, the liquid inlet pipe 2 and the liquid outlet pipe 3 are independently installed on site, thereby reducing leakage points and improving the reliability of the pipeline device.

[0040] It should be noted that this embodiment does not limit the specific method for forming the integrated structure of the main line 1, the liquid inlet pipe 2, and the liquid outlet pipe 3. In some embodiments, the liquid inlet pipe 2 and the main line 1, and the liquid outlet pipe 3 and the main line 1 are welded separately. In other words, this embodiment achieves the integrated structure of the main line 1, the liquid inlet pipe 2, and the liquid outlet pipe 3 through welding. Of course, in other embodiments, the main line 1, the liquid inlet pipe 2, and the liquid outlet pipe 3 can also be integrally formed.

[0041] In addition, since the pipeline device is an integrated structure, when the pipeline device is installed as a whole, in order to ensure that the first interface 21 of the liquid inlet pipe 2 can be smoothly docked with the power device and the second interface 31 of the liquid outlet pipe 3 can be smoothly docked with the target device, the embodiment of the utility model arranges a hose 4 at at least one preset position, utilizes the deformability of the hose 4, and compensates for the assembly error by the deformation amount of the hose 4 to fine-tune the positions of the first interface 21 and the second interface 31, thereby ensuring that the first interface 21 can be smoothly docked with the power device and the second interface 31 can be smoothly docked with the target device.

[0042] It should be noted that the hose 4 can be arranged between the liquid inlet pipe 2 and the main line 1, or can be arranged in the liquid inlet pipe 2, or between the liquid outlet pipe 3 and the main line 1, or can be arranged in the liquid outlet pipe 3, or the hose 4 can be arranged at multiple locations at these positions, as long as it can play the role of adjusting the position of the first interface 21 and / or the second interface 31.

[0043] In addition, this embodiment does not limit the specific structure and material of the hose 4. In some embodiments, the hose 4 is a metal hose 4.

[0044] It should be noted that this embodiment does not limit the specific number of liquid inlet pipes 2. The number of liquid inlet pipes 2 can be one or at least two. In some embodiments, the number of liquid inlet pipes 2 is two. It is understood that when the number of liquid inlet pipes 2 is at least two, the liquid inlet pipes 2 are connected one-to-one with a corresponding number of power devices, which is conducive to realizing a solution of multiple power devices. The multiple power devices can work alternately or have one backup and the other in use, etc., which is convenient for different working scenarios.

[0045] Furthermore, considering the convenience of setting up the hose 4, in some embodiments, the number of the liquid inlet pipes 2 is at least two, one of which is connected to one end of the main line 1 through the hose 4, and the remaining liquid inlet pipes 2 are connected to the side wall of the pipe body of the main line 1.

[0046] That is, in this embodiment, the hose 4 is disposed between the end of the main line 1 and the end of one of the liquid inlet pipes 2, facilitating connection of the hose 4 to the main line 1 and the liquid inlet pipe 2. In some embodiments, the hose 4 extends along the length of the main line 1, and the liquid inlet pipe 2 connected to the hose 4 includes a fifth bend to achieve reversal of the liquid inlet pipe 2 through the fifth bend, ensuring that the liquid inlet pipe 2 is properly positioned.

[0047] In addition, in some embodiments, all the liquid inlet pipes 2 are located on the same side of the main line 1 .

[0048] It can be understood that this layout can save space and make the structure compact, while facilitating the connection between each liquid inlet pipe 2 and the power device.

[0049] Furthermore, in some embodiments, at least one liquid inlet pipe 2 connected to the side wall of the tube body of the main line 1 includes a first tube body 231, a first bend 232 and a second tube body 233, and the first tube body 231 is connected to the main line 1; the first bend 232 is connected between the first tube body 231 and the second tube body 233 to achieve the reversal of the liquid inlet pipe 2, and the second tube body 233 faces the side of the liquid inlet pipe 2 connected to one end of the main line 1 through the hose 4, and the first interface 21 is connected to the second tube body 233.

[0050] That is to say, the liquid inlet pipe 2 in this embodiment is reversed through the first bend pipe 232, so that the first interface 21 is directed toward the side of the liquid inlet pipe 2 connected to one end of the main line 1 through the hose 4. This is conducive to making the first interface 21 have a suitable position, facilitating the first interfaces 21 of each liquid inlet pipe 2 to be connected to the power device respectively, and facilitating the centralized layout of the power device.

[0051] In some embodiments, there are two liquid inlet pipes 2. For the sake of convenience of description, the two liquid inlet pipes 2 are respectively referred to as the first liquid inlet pipe 22 and the second liquid inlet pipe 23. For example, the first liquid inlet pipe 22 is connected to one end of the main line 1 through a hose 4, and the second liquid inlet pipe 23 is connected to the side wall of the tube body of the main line 1. The second liquid inlet pipe 23 includes a first tube body 231, a first bend 232 and a second tube body 233. The second tube body 233 faces the side where the first liquid inlet pipe 22 is located, so that the first interface 21 of the second liquid inlet pipe 23 faces the side where the first liquid inlet pipe 22 is located.

[0052] In addition, considering the simplicity of the structure, the first interface 21 of the liquid inlet pipe 2 connected to one end of the main line 1 through the hose 4 can be provided at the end of the liquid inlet pipe 2 away from the main line 1 along the length direction of the liquid inlet pipe 2. For example, the first interface 21 of the first liquid inlet pipe 22 is provided at the end of the first liquid inlet pipe 22 away from the main line 1, and the first interface 21 is located in the length direction of the first liquid inlet pipe 22.

[0053] In addition, in some embodiments, the liquid outlet pipe 3 and the liquid inlet pipe 2 are located on the same side of the main line 1 .

[0054] That is to say, the liquid outlet pipe 3 and the liquid inlet pipe 2 in this embodiment are arranged on the same side relative to the main pipe 1. This layout can further save space and facilitate reasonable layout.

[0055] Furthermore, in some embodiments, the number of the liquid inlet pipes 2 is at least two, and all the liquid inlet pipes 2 are located on the same side of the liquid outlet pipe 3 .

[0056] This layout makes it easy to connect each liquid inlet pipe 2 with the power device, and also facilitates the centralized layout of the power device, making the structure compact, and also helps to avoid structural interference, etc., and facilitates layout.

[0057] In addition, in order to facilitate the appropriate positioning of the second interface 31, in some embodiments, the liquid outlet pipe 3 includes a third tube body 32 connected to the main line 1 and a special-shaped tube connected to the third tube body 32, the special-shaped tube is located on the side of the liquid outlet pipe 3 away from the liquid inlet pipe 2, and the second interface 31 is provided at one end of the special-shaped tube away from the third tube body 32.

[0058] That is, in this embodiment, by providing the special-shaped tube and utilizing the shape of the special-shaped tube, the second interface 31 is located at a suitable position, which facilitates the connection between the second interface 31 and the target device.

[0059] It should be noted that this embodiment does not limit the specific structure of the special-shaped tube, as long as the direction of the special-shaped tube can enable the second interface 31 to be located at a suitable position.

[0060] In some embodiments, the special-shaped tube includes a second bend 33 connected to the third tube body 32, a fourth tube body 34 connected to the second bend 33, a third bend 35 connected to the fourth tube body 34, a fifth tube body 36 connected to the third bend 35, and a fourth bend 37 connected to the fifth tube body 36. The second interface 31 is connected to the fourth bend 37, the fifth tube body 36 and the third tube body 32 are located on the same side of the fourth tube body 34, and the second interface 31 is facing away from the third tube body 32.

[0061] That is to say, this embodiment changes the direction of the special-shaped tube through the second bend 33, the third bend 35 and the fourth bend 37, so that the third tube body 32, the second bend 33, the fourth tube body 34, the third bend 35 and the fifth tube body 36 form a U-shaped structure, and the second interface 31 is oriented away from the third tube body 32 to facilitate the connection of the second interface 31 with the target device.

[0062] It should be noted that the fourth tube body 34 can be parallel to the third tube body 32, or the fourth tube body 34 can have a certain angle with respect to the third tube body 32, so that the opening size of the U-shaped structure can be changed. For example, in some embodiments, the fourth tube body 34 is inclined in a direction away from the third body from the end connected to the third bend 35 to the end connected to the fourth bend 37. That is, the distance between the fourth tube body 34 and the third tube body 32 gradually increases from the closed end to the open end of the U-shaped structure, so that the opening of the U-shaped structure expands outward, which is conducive to connecting the second interface 31 with the target device.

[0063] It can be understood that since the U-shaped structure has an opening and there is no structural limit at the opening, under the action of external force, the second interface 31 can be positioned appropriately by causing the opening of the U-shaped structure to produce an appropriate amount of deformation to compensate for the position error of the second interface 31 caused by the assembly error.

[0064] In addition, in some embodiments, the main line 1 , the liquid inlet pipe 2 , and the liquid outlet pipe 3 are located in the same plane.

[0065] That is to say, the main line 1, the liquid inlet pipe 2 and the liquid outlet pipe 3 are arranged in the same plane, which is conducive to saving space perpendicular to the plane direction of the main line 1, the liquid inlet pipe 2 and the liquid outlet pipe 3, making the structure compact and easy to install, and helping to avoid interference with other structural parts during the overall installation of the pipeline device.

[0066] In addition, in some embodiments, the liquid inlet pipe 2 is provided with a one-way valve 5 for preventing the liquid in the main line 1 from flowing to the first interface 21 .

[0067] That is, the present embodiment utilizes the one-way valve 5 to prevent the liquid in the liquid inlet pipe 2 from flowing back, thereby ensuring the correctness of the liquid delivery direction and the stability of the liquid flow.

[0068] In addition, in some embodiments, a connector 11 is provided at one end of the main pipe 1 away from the liquid inlet pipe 2, and the connector 11 is used to install sensors, etc. That is, the main pipe 1 in this embodiment can also serve as a support for necessary components such as sensors.

[0069] In addition, the above embodiments do not limit the specific structures of the first interface 21 and the second interface 31. For example, in some embodiments, the first interface 21 and the second interface 31 are chucks respectively.

[0070] In addition to the above-mentioned pipeline device, the present invention also provides a heat exchange device including the pipeline device disclosed in the above-mentioned embodiment. The heat exchange device also includes a heat exchanger and a power device connected to the liquid outlet pipeline of the heat exchanger. The power device is connected to the liquid inlet pipe 2 of the above-mentioned pipeline device. For the structure of other parts of the heat exchange device, please refer to the relevant technology and will not be repeated in this article.

[0071] The key point of this embodiment is that the heat exchange device adopts the piping device disclosed in any one of the above embodiments, at least including the beneficial effects of the above piping device, which will not be repeated here.

[0072] It should also be noted that, in this specification, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0073] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
