[0032] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments only represent some 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 labor fall within the scope of protection of the present application.

[0033] The core of the present application is to provide a CDU pipeline system, which can reduce the assembly difficulty of the equipment in the box of the CDU system.

[0034] The first specific embodiment of the CDU pipeline system provided by the present application is shown in the figure. Figure 1 and Figure 2, including a pipeline body, the pipeline body including a first pipe body 1, a second pipe body 2 and a connecting pipe 3, the first pipe body 1 being connected to a first port 32 of the connecting pipe 3, and a second port 33 of the connecting pipe 3 being connected to the second pipe body 2.

[0035] Wherein, for the deformation direction of the connecting pipe 3, it can include torsion and bending deformation, and / or, inner and outer diameter change, and / or, length expansion and contraction deformation. The deformation of the connecting pipe 3 can be elastic or plastic. In addition, the connecting pipe 3 can be locally deformed or integrally deformed.

[0036] At this time, the ports of the pipeline body for connecting other equipment are the remaining ports of the first pipe body 1 and the second pipe body 2, and the equipment that can be connected includes pump body, heat exchange device, expansion tank, etc., or valve body structure or other section of pipeline for liquid transmission.

[0037] The CDU pipeline system in the embodiment has a first liquid cooling pipe, and the middle part of the first liquid cooling pipe has a deformable connecting pipe 3, which can ensure that the relative positions of the first pipe body 1 and the second pipe body 2 have a certain degree of adjustable space. When there is an assembly or machining error in the equipment connected by the first pipe body 1 and the second pipe body 2, the error can be accommodated by the deformation of the connecting pipe 3, ensuring the smooth assembly and reducing the assembly difficulty. In addition, since the connecting pipe 3 is located in the middle part of the first liquid cooling pipe, other equipment can be connected through the first pipe body 1 and the second pipe body 2, and the first pipe body 1 and the second pipe body 2 can be selected according to the connection requirements of other equipment, reducing the influence of the deformation section on the original connection mode between the pipeline body and other equipment, and reducing the equipment modification cost.

[0038] Specifically, the first pipe body 1 and the second pipe body 2 are both non-deformable hard pipes, which can reduce the assembly difficulty and improve the stability of placing in the box. The connecting pipe 3 is a deformable flexible pipe, which has good accommodation capacity for assembly errors and a large selection range. In addition, since the connecting pipe 3 is located between the two hard pipes, the hard pipes are connected to other equipment, which is a certain distance from the flexible pipe, and can also reduce the damage to the connecting pipe 3 caused by repeated disassembly and assembly for maintenance, thereby ensuring the service life.

[0039] Wherein, the connecting pipe 3, the first pipe body 1 and the second pipe body 2 can all be made of metal materials to ensure the service life. Specifically, the connecting pipe 3 can be a stainless steel flexible pipe, a copper flexible pipe, etc., which has good corrosion resistance and wear resistance. Of course, the connecting pipe 3 can also be made of PVC pipe, PE pipe, PP pipe, etc. according to actual conditions.

[0040] Wherein, in order to ensure the deformation ability of the connecting pipe 3, it can be a corrugated pipe, at this time, the connecting pipe 3 can be bent and deformed, and has a certain expansion ability in the length direction, which can ensure its adaptability to assembly error. Alternatively, it can also be directly provided as a pipe body with a certain elasticity, and the overall length of the connecting pipe 3 is adjusted by elastic expansion, and it can also be twisted or bent; or the connecting pipe 3 is a telescopic sleeve type pipe body, at this time the overall length of the connecting pipe 3 can be adjusted by the relative movement of different sleeves in the pipe body.

[0041] Alternatively, the length of the connecting pipe 3 in the length direction can be fixed, and it can be twisted or bent, at this time, when selecting the connecting pipe 3, the length of the connecting pipe 3 needs to be greater than the preset connection requirement between the first pipe body 1 and the second pipe body 2, so that when the assembly of the first pipe body 1 and the second pipe body 2 deviates from the preset position relationship, the actual assembly requirement can be met by the inclination or bending deformation of the connecting pipe 3.

[0042] Of course, in other embodiments, the connecting pipe 3 can also be a hard pipe, or a pipe body structure combining soft and hard pipes. When a hard pipe is selected, it can include different pipe segments connected in rotation and communication, and the deformation can be realized by the relative movement between these pipe segments to accommodate assembly errors.

[0043] As shown in Figure 1 , one end of the first pipe body 1 is connected to the first port 32 of the connecting pipe 3, and the first pipe body 1 also has another port to connect other equipment, which in this embodiment is specifically connected to the first pump body 51, and in other embodiments can also be other equipment. The second port 33 of the connecting pipe 3 is connected to the middle opening of the second pipe body 2, and the portions of the second pipe body 2 located on both sides of the connecting pipe 3 are respectively the first pipe segment 21 and the second pipe segment 22, and the first pipe segment 21 and the second pipe segment 22 have ports respectively, wherein the port of the first pipe segment 21 is connected to the second pump body 52, and the port of the second pipe segment 22 can be connected to an external cooling water system. In other embodiments, the first pipe segment 21 and the second pipe segment 21 can also be connected to other equipment.

[0044] At this time, the first pipe body 1, the second pipe body 2 and the connecting pipe 3 form a three-way structure with three branches, and the connecting pipe 3 is located at the junction and can be deformed in different directions to accommodate errors in different directions. Of course, in other embodiments, the first pipe body 1, the connecting pipe 3 and the second pipe body 2 can be connected in sequence to form a linear pipe, which can be rearranged into a straight line, a U shape, a Z shape, etc.

[0045] In the arrangement direction, as shown in Figure 1As shown, the first port 32 and the second port 33 of the connecting pipe 3 are arranged along the first direction X. In the second direction Y, the first pipe section 21 and the second pipe section 22 are respectively located on the two sides of the connecting pipe 3. The first direction X and the second direction Y can be two perpendicular directions. The first pipe body 1 is a bent pipe, and part of the structure is parallel to the first direction X, and part of the structure is bent towards the direction on the same side of the first pipe section 21 in the second direction Y. At this time, the orientations of the first pipe section 21 and the first pipe body 1 away from the ports of the hose 3 are unified, and after the first pump body 51 and the second pump body 52 are assembled in the box, the assembly of the first liquid cooling pipe on the same side of the first pump body 51 and the second pump body 52 can be facilitated.

[0046] In the second pipe body 2, the first pipe section 21 can be parallel to the second direction Y, the part of the second pipe section 22 close to the first pipe section 21 can be parallel to the second direction Y and arranged in line with the first pipe section 21, and the second pipe body 2 can further include a remaining part abutting the second pipe section. The extension direction of the remaining part can be set as needed, and other branches can also be included.

[0047] As shown in Figure 1 The first shutoff valve 41 is further arranged between the connecting pipe 3 and the first pipe body 1, and the second shutoff valve 42 is further arranged on the first pipe section 21. Specifically, the first shutoff valve 41, the second shutoff valve 42 and other shutoff valves can be selected as ball valves. Of course, in other embodiments, the first shutoff valve 41, the second shutoff valve 42 or other shutoff valves can also be selected as stop valves, butterfly valves or other valves according to actual needs. In addition, in other embodiments, the second shutoff valve 42 can also be arranged between the second pipe body 2 and the connecting pipe 3.

[0048] By adding the first shutoff valve 41 and the second shutoff valve 42, the connection between the first pump body 51, the second pump body 52 and the connecting pipe 3 can be connected or cut off as needed, and the pump body can be more flexibly put into use.

[0049] Specifically, the first port 32 of the connecting pipe 3 is fixedly connected to the first shutoff valve 41 through the first clamp 31, which is convenient to disassemble and assemble, and the first shutoff valve 41 can be conveniently replaced and maintained. The second port 33 of the connecting pipe 3 is welded to the second pipe body 2, and the second shutoff valve 42 is arranged on the first pipe section 21 to ensure the reliability of the connection.

[0050] As shown in Figure 2 The first pump body 51 and the second pump body 52 are connected to the refrigerant passage of the heat exchange device 6, and in the second direction Y, the first pump body 51 and the second pump body 52 are located on one side of the connecting pipe 3, and the heat exchange device 6 is located on the other side of the connecting pipe 3. Among them, the area where the connecting pipe 3 is arranged is usually less disturbed by electricity.

[0051] In this embodiment, the first pump body 51 and the second pump body 52 are connected in parallel to the refrigerant passage of the heat exchange device 6, and can work alternately or simultaneously, so as to ensure the continuous heat exchange. In other embodiments, the first pump body 51 and the second pump body 52 can also be connected in series to the refrigerant passage of the heat exchange device 6. The refrigerant passage of the heat exchange device 6 is used for passing the cooling medium, and the heat medium passage of the heat exchange device 6 is used for passing the object to be cooled.

[0052] In addition, in the first direction X, the heat exchange device 6 and the connecting pipe 3 are located on the same side of the second pipe section 22, and in combination with the position relationship between the connecting pipe 3 and the heat exchange device 6 in the second direction Y, the intersection of the connecting pipe 3 and the second hard pipe 2 can assist in assembly positioning, and the intersection can be generally close to one vertex of the heat exchange device 6.

[0053] Specifically, the first pump body 51 and the heat exchange device 6 are further connected with the third shut-off valve 43, and the second pump body 52 and the heat exchange device 6 are further connected with the fourth shut-off valve 44, and the first pump body 51 and the second pump body 52 are connected in parallel between the refrigerant passage of the heat exchange device 6 and the second pipe section 22. The first pump body 51 and the first shut-off valve 41 and the third shut-off valve 43 are detachably connected, and the second pump body 52 and the second shut-off valve 42 and the fourth shut-off valve 44 are detachably connected, and the detachable connection can be achieved by the second clamp connection.

[0054] At this time, the first pump body 51 and the second pump body 52 can be used alternately, and the first shut-off valve 41 and the third shut-off valve 43 are closed at the same time, the first pump body 51 is removed, the second shut-off valve 42 and the fourth shut-off valve 44 are opened, the second pump body 52 is connected between the refrigerant passage of the heat exchange device 6 and the second pipe section 22, and the CDU system can still operate normally; at the same time, the second shut-off valve 42 and the fourth shut-off valve 44 are closed, the second pump body 52 is removed, the first shut-off valve 41 and the third shut-off valve 43 are opened, and the first pump body 51 is connected between the refrigerant passage of the heat exchange device 6 and the second pipe section 22, so that the CDU system can still operate normally, thereby ensuring the normal operation of the equipment and realizing the online maintenance of the pump body.
