[0039] In the description of the utility model, it needs to be explained that unless otherwise explicitly specified and limited, the terms "mounting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through intermediate medium.

[0040] Referring to Figures 3 to 7 The embodiments of the present application provide a cluster level liquid cooling pipeline connection structure, comprising: a plurality of battery packs 1 and two mother pipes 2. Each battery pack 1 is arranged in sequence, each battery pack 1 has a cooling plate assembly 11, two water nozzles 114 are arranged on the cooling plate assembly 11, and the two water nozzles 114 are respectively water inlet nozzles and water outlet nozzles. Two mother pipes 2 are arranged along the arrangement direction of each battery pack 1, and two mother pipes 2 are respectively water inlet mother pipes 2 and water outlet mother pipes 2, the water inlet mother pipes 2 are directly connected to the water inlet nozzles of each battery pack 1, and the water outlet mother pipes 2 are directly connected to the water outlet nozzles of each battery pack 1. The cluster level liquid cooling pipeline connection structure of the present application does not need to use a sub-pipe 3 to connect between the mother pipe 2 and the water nozzle 114, directly connects the water inlet mother pipe 2 to the water inlet nozzle of each battery pack 1, and connects the water outlet mother pipe 2 to the water outlet nozzle of each battery pack 1, saves materials, reduces the liquid injection amount, reduces the manufacturing cost, and the pipeline connection structure is simple and not messy, convenient to assemble, and high in assembly efficiency.

[0041] As Figure 3 And Figure 4As shown, the main pipe 2 has multiple three-way valves 21, each of which is spaced apart along the length of the main pipe 2. Each three-way valve 21 has an external extension nozzle and two main pipe connecting nozzles. The main pipe connecting nozzles are connected to the pipe body of the main pipe 2, and the external extension nozzles are connected to the water nozzle 114 of the battery pack 1. The main pipe 2 includes multiple pipe segments, and two main pipe connecting nozzles are respectively connected between two adjacent pipe segments in the main pipe 2. The main pipe connecting nozzles and the pipe segments can be connected by welding or hot melt. For example, when the main pipe 2 is a steel pipe, the main pipe connecting nozzles and the pipe segments can be connected by welding; when the main pipe 2 is a PVC pipe, the main pipe connecting nozzles and the pipe segments can be connected by hot melt. The external extension nozzle is directly connected to the water inlet or outlet of the battery pack 1. The external extension nozzle of the three-way valve 21 can be made of flexible material to reduce the impact of bumps and misalignment on the connection of the water nozzle 114 of the battery pack.

[0042] like Figure 3 and Figure 4 As shown, a valve cap 4 is provided on the outwardly extending nozzle, and the valve cap 4 is sleeved on the water spout 114. The valve cap 4 can be snap-fitted with the water spout 114. The valve cap 4 and the outwardly extending nozzle can be an integrally formed structure, or can be a fixedly connected or detachable connection structure. The connection structure between the valve cap 4 and the water spout 114 can be similar to the connection structure between the water inlet pipe of a washing machine and the water outlet of a faucet. The connection structure between the valve cap 4 and the water spout 114 is a mature technology in this field, and its specific structure will not be described in detail in this application.

[0043] like Figure 6 As shown, a plurality of battery modules 12 are arranged on the cooling plate assembly 11, and two water nozzles 114 are arranged on one side of the cooling plate assembly 11 along the arrangement direction of the battery modules 12. The arrangement direction of the battery modules 12 is the width direction of the water cooling plate, that is, the water nozzles 114 are located on one side of the water cooling plate along the width direction, that is, the water nozzles 114 are located on one length side of the water cooling plate.

[0044] like Figure 5 and Figure 6 As shown, the two water spouts 114 are located near a corner of one side of the cooling plate assembly 11. The main pipe 2 is typically located near a corner of one side of the cooling plate assembly 11, without affecting the arrangement of other structures of the battery pack 1. The two water spouts 114 are located opposite the main pipe 2, facilitating close connection to the main pipe 2.

[0045] like Figure 5 and Figure 6As shown, the cooling plate assembly 11 includes a cooling plate 111, two end beams 112, and two side beams 113. The two end beams 112 are disposed on opposite sides of the cooling plate 111 along a first direction, which is the length of the cooling plate 111. The two side beams 113 are disposed on opposite sides of the cooling plate 111 along a second direction, which is the width of the cooling plate 111. The water nozzle 114 is disposed through the side beam 113 and connected to the cooling plate 111. The water nozzle 114 is connected to the cooling channel of the cooling plate 111. The two water nozzles 114 are respectively an inlet and an outlet. In the prior art, the inlet and outlet are disposed on the end beams 112. There is a certain distance between the inlet and outlet, and they are far away from the main pipe 2, so they need to be connected to the main pipe 2 through the sub-pipes 3. The distance between the water inlet and the water outlet of the cluster-level liquid cooling pipe connection structure of the present application is very close, which is convenient for direct connection with the two mother pipes 2 respectively, without the need for the use of sub-pipes 3 for connection.

[0046] like Figure 7 As shown, the water nozzle 114 includes a horizontal pipe portion 1141 and a vertical pipe portion 1142 extending along the thickness of the cooling plate 111. The horizontal pipe portion 1141 is installed through the side beams 113, and the vertical pipe portion 1142 is connected to the cooling plate 111. The two side beams 113 are located on one side of the cooling plate 111 along the thickness direction. The horizontal pipe extends parallel to the plane of the cooling plate 111, and the vertical pipe needs to be connected to connect to the cooling plate 111.

[0047] like Figure 7 As shown, the horizontal pipe portion 1141 and the vertical pipe portion 1142 are smoothly connected by the arc pipe 1143. This is beneficial to reducing water flow resistance and facilitating the smooth passage of cooling water.

[0048] like Figures 5 to 7 As shown, the battery pack 1 has a cover 13, which is sealed and connected to the side beam 113 and the end beam 112. The side beam 113 is a tube body, and the side beam 113 has an inner wall 1131 and an outer wall 1132. A tube cavity is formed between the inner wall 1131 and the outer wall 1132. The horizontal tube portion 1141 is arranged to pass through the inner wall 1131 and the outer wall 1132, and the horizontal tube portion 1141 is sealed and connected to the inner wall 1131 to prevent external water leakage. Water enters the interior of the battery pack 1 through the gap between the water nozzle 114 and the side beam 113, thereby causing a safety accident. The gap between the water nozzle 114 and the side beam 113 can be sealed by welding, or by using a sealing ring, sealant or other sealing methods.

[0049] likeFigure 5 and Figure 7 As shown in the figure, the outer side wall 1132 is provided with a notch part 1132a. The horizontal pipe part 1141 of the two water taps 114 penetrates the notch part 1132a. The distance between the two water taps 114 is small, the size of the notch part 1132a is small, and the position of the notch part 1132a does not need to bear too much weight. If two notch parts 1132a are made, the structure is complex and the process is difficult. Therefore, only one notch part 1132a is provided, so that the two water taps 114 can penetrate, simplifying the structure of the outer side wall 1132 and the production process.

[0050] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above-mentioned technical content without departing from the scope of the present application, and any simple modification, equivalent change and modification of the above-mentioned technical content are still within the scope of the present application.
