[0046] Example 1

[0047] Combined with Figure 1-6 , this embodiment provides a liquid cooling pipeline system, including:

[0048] Liquid inlet pipe 3;

[0049] Liquid outlet pipe 4;

[0050] A plurality of first liquid cooling plates 1 and a plurality of second liquid cooling plates 2 are arranged alternately, the first inlets 11 of the plurality of first liquid cooling plates 1 are all connected to the liquid inlet pipe 3, the first outlets 12 of the plurality of first liquid cooling plates 1 are all correspondingly connected to the second inlets 21 of the plurality of second liquid cooling plates 2, and the second outlets 22 of the plurality of second liquid cooling plates 2 are all connected to the liquid outlet pipe 4.

[0051] Specifically, during operation, first, the coolant flows into the first liquid cooling plates 1 from the liquid inlet pipe 3 and the first inlets 11 of the first liquid cooling plates 1 in sequence; then, the coolant flows through the first liquid cooling plates 1; then, the coolant flows out of the first liquid cooling plates 1 from the first outlets 12 of the first liquid cooling plates 1, and flows into the second liquid cooling plates 2 from the second inlets 21 of the second liquid cooling plates 2; further, the coolant flows through the second liquid cooling plates 2; finally, the coolant flows out of the second liquid cooling plates 2 from the second outlets 22 of the second liquid cooling plates 2, and flows to the liquid outlet pipe 4; in summary, the liquid cooling pipe A first liquid cooling plate 1 and a second liquid cooling plate 2 in the pipeline system are connected in series and combined into a liquid cooling unit 100, and a plurality of liquid cooling units 100 are connected in parallel, which not only facilitates the consistency of the liquid inlet and outlet of the plurality of liquid cooling units 100, thereby reducing the flow resistance of the coolant and thus improving the heat dissipation efficiency, but also, when one of the first liquid cooling plates 1 or the second liquid cooling plates 2 fails, only the liquid cooling unit 100 where the first liquid cooling plate 1 or the second liquid cooling plate 2 is located cannot work, and other liquid cooling units 100 can work, which facilitates the high fault tolerance rate of the liquid cooling pipeline system;

[0052] A plurality of first liquid cooling plates 1 and a plurality of second liquid cooling plates 2 are arranged alternately, specifically referring to a first liquid cooling plate 1, a second liquid cooling plate 2, another first liquid cooling plate 1 and so on, and it is necessary to ensure that the number of the plurality of first liquid cooling plates 1 and the number of second liquid cooling plates 2 are equal, wherein the number of the plurality of first liquid cooling plates 1 and the number of the plurality of second liquid cooling plates 2 are preferably three, which is equivalent to the number of the liquid cooling units 100 being preferably three.

[0053] Further, such as Figure 1-3 The first inlets 11 of the first liquid cooling plates 1 and the liquid inlet pipe 3, the first outlets 12 of the first liquid cooling plates 1 and the second inlets 21 of the second liquid cooling plates 2, and the second outlets 22 of the second liquid cooling plates 2 and the liquid outlet pipe 4 are all connected through a quick release assembly 5.

[0054] Specifically, the quick-release assembly 5 facilitates quick disassembly and assembly.

[0055] Further, such as Figure 5 , the quick-release assembly 5 comprises:

[0056] Branch pipe 53;

[0057] Two first quick-release tubes 51 respectively connected to both ends of the branch tube 53;

[0058] A second quick-release tube 52 connected to the liquid inlet pipe 3, the liquid outlet pipe 4, the first inlets 11 of the first liquid cooling plates 1, the first outlets 12 of the first liquid cooling plates 1, the second inlets 21 of the second liquid cooling plates 2 or the second outlets 22 of the second liquid cooling plates 2;

[0059] The first quick-release tube 51 and the second quick-release tube 52 are detachably connected.

[0060] Specifically, the branch pipe 53 is used to carry the two first quick-release pipes 51 ; since the first quick-release pipe 51 and the second quick-release pipe 52 are detachably connected, it is convenient to make the branch pipe 53 and the two first quick-release pipes 51 detachably connected to the second quick-release pipe 52 .

[0061] Further, such as Figure 6 ,

[0062] The first quick-release tube 51 comprises:

[0063] First tube body 511;

[0064] a tapered portion 512 provided at one end of the first tube body 511;

[0065] A push-pull block 513 movably connected to the other end of the first pipe body 511;

[0066] Two buckles 514 respectively connected to the two sides of the push-pull block 513;

[0067] One end of the first pipe body 511 is connected to the branch pipe 53 through the tapered portion 512;

[0068] The second quick-release tube 52 includes:

[0069] Second tube body 521;

[0070] A slot 522 provided on the second tube body 521;

[0071] Among them, one end of the second tube body 521 is connected to the liquid inlet pipe 3, the liquid outlet pipe 4, the first inlet 11 of several first liquid cooling plates 1, the first outlet 12 of several first liquid cooling plates 1, the second inlet 21 of several second liquid cooling plates 2 or the second outlet 22 of several second liquid cooling plates 2, the slot 522 and the two buckles 514 are matched, and the other end of the first tube body 511 is connected to the other end of the second tube body 521.

[0072] Specifically, during installation, first, preliminarily match the other end of the second tube body 521 with the other end of the first tube body 511; then, push the push-pull block 513 toward the center direction of the other end of the second tube body 521, and the push-pull block 513 drives the two buckles 514 to move toward the center direction of the other end of the second tube body 521. During the movement, the two buckles 514 are in a matching state with the slots 522. When the two buckles 514 are located at the center position of the other end of the second tube body 521, the distance between the two buckles 514 is enlarged; finally, continue to push the push-pull block 513, and the push-pull block 513 drives the two buckles 514 to pass the center position of the other end of the second tube body 521, and the distance between the two buckles 514 is restored, thereby locking the other end of the second tube body 521, and then completing the installation;

[0073] During disassembly, first, pull the push-pull block 513 toward the center direction of the other end away from the second tube body 521, and the push-pull block drives the two buckles 514 to move toward the center direction of the other end away from the second tube body 521. During the movement, the two buckles 514 are in a matching state with the slots 522. When the two buckles 514 are located at the center position of the other end of the second tube body 521, the distance between the two buckles 514 is enlarged; further, continue to pull the push-pull block 513, and the push-pull block 513 drives the two buckles 514 to pass the center position of the other end of the second tube body 521, and the distance between the two buckles 514 is restored, thereby unlocking the other end of the second tube body 521; finally, separate the other end of the second tube body 521 from the other end of the first tube body 511, thereby completing the disassembly;

[0074] The first tube body 511 is used to carry the tapered portion 512 ; the tapered portion 512 is used to cooperate with the groove in the branch tube 53 , so as to effectively prevent the first tube body 511 and the branch tube 53 from being separated from each other.

[0075] Further, such as Figure 6 The first quick-release tube 51 further includes a receiving groove 515 disposed at one end of the push-pull block 513 away from the buckle 514 .

[0076] Specifically, the receiving groove 515 is used to receive a dismantling tool such as a wrench or a screwdriver, so as to facilitate the dismantling tool to pull the push-pull block 513 toward the center direction away from the other end of the second tube body 521 .

[0077] Further, such as Figure 6 The second quick-release tube 52 further includes a limiting plate 523 sleeved on the outside of the second tube body 521 , and the limiting plate 523 contacts the other end of the first tube body 511 .

[0078] Specifically, the limiting plate 523 is used to limit the relative axial position between the other end of the second tube body 521 and the other end of the first tube body 511 .

[0079] Further, such as Figure 6 A sealing ring 54 is provided at the connection between one end of the first tube body 511 and the branch tube 53 .

[0080] Specifically, the sealing ring 54 is used to increase the sealing performance between one end of the first tube body 511 and the branch tube 53 , and the sealing ring 54 may be made of silicone rubber, fluororubber or the like.

[0081] Furthermore, the inner diameter of the branch pipe 53 is 12 mm.

[0082] Specifically, the inner diameter of 12 mm facilitates reducing the volume of the branch pipe 53 , thereby reducing the space occupied by the branch pipe 53 .

[0083] Furthermore, the inner diameters of the liquid inlet pipe 3 and the liquid outlet pipe 4 are both 25 mm.

[0084] Specifically, the inner diameter of 25 mm makes it easier for the coolant to be obstructed in the liquid inlet pipe 3 and the liquid outlet pipe 4, thereby further reducing the flow resistance of the coolant and further increasing the heat dissipation efficiency.

[0085] Example 2

[0086] Combined with Figure 1-6 This embodiment provides an energy storage converter, including a liquid cooling pipeline system as in Embodiment 1, and also including a plurality of circuit boards 6, wherein the plurality of circuit boards 6 are correspondingly connected to a plurality of first liquid cooling plates 1 and a plurality of second liquid cooling plates 2.

[0087] Specifically, each first liquid cooling plate 1 is used to carry a circuit board 6, and each second liquid cooling plate 2 is used to carry a circuit board 6. In other words, the number of the plurality of circuit boards 6 is equal to the sum of the number of the first liquid cooling plates 1 and the number of the second liquid cooling plates 2.

[0088] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto.
