[0002] Energy storage containers play a crucial role in current energy storage technology, finding widespread application in a wide range of sectors, including power systems, renewable energy generation, and industrial and commercial applications. Within energy storage containers, the battery pack is undoubtedly the core component and the key energy storage unit. The operating temperature of the battery pack has a crucial impact on the performance and service life of the entire energy storage system. To precisely control the battery pack temperature and maintain it within the optimal operating temperature range, existing energy storage container structures typically employ a large number of liquid cooling plates for temperature regulation. However, traditional liquid cooling plates have significant drawbacks in practical applications. Their relatively fixed inlet and outlet locations make installing cooling pipes between these numerous plates extremely cumbersome and inconvenient. Installation workers often spend considerable time and effort connecting and debugging the pipes, which is not only inefficient but also prone to problems such as loose connections and poor sealing, compromising the temperature control and stability of the entire energy storage system. Therefore, the development of a blind-plug connection device for liquid cooling plates is urgently needed. This device could significantly enhance the convenience of liquid cooling plate installation and connection, thereby effectively optimizing the overall performance and user experience of the energy storage container.

[0014] like Figure 1As shown, this specific embodiment adopts the following technical solutions: a liquid cold plate blind plug connection device, including an outer shell 1, an inner cavity 2, a connecting pipe 3, a one-way valve 4, a one-way valve 5, a linkage valve 6, a connecting pipe 2 7, an inner cavity 8, a one-way valve 3 9, a one-way valve 4 10, a three-way pipe 11 and a three-way pipe 2 12; the inner cavity 2 is provided inside the left front side of the outer shell 1, the inner cavity 2 8 is provided inside the left rear side of the outer shell 1, and the linkage valve 6 is fixedly connected to the central interior of the outer shell 1; a connecting pipe 3 is provided at the left opening of the inner cavity 2, and the right front outlet of the inner cavity 2 is connected to the linkage valve 6 through the one-way valve 4.

[0015] like Figure 2As shown, the specific structure of the linkage valve 6 includes a fixed housing 61, a guide hole cavity 62, a gear 63, a rack 64, a spring 65, a piston cavity 66, a piston 67, a connecting pipe 68, an output hole 1 69, a valve core 1 610, a connecting shaft 611, a discharge hole 1 612, a valve core 2 613, a discharge hole 2 614, a valve core 3 615, an output hole 2 616 and a valve core 4 617; the outside of the fixed housing 61 is fixedly connected to the center of the outer housing 1, and the inside of the fixed housing 61 is from front to back. The output hole 1 69, the discharge hole 1 612, the discharge hole 2 614 and the output hole 2 616 are sequentially provided. The front and rear sides of the fixed housing 61 are internally provided with a guide hole cavity 62, and the left side of the guide hole cavity 62 is provided with a piston cavity 66; the inner centers of the output hole 1 69, the discharge hole 1 612, the discharge hole 2 614 and the output hole 2 616 are respectively movably connected with the valve core 1 610, the valve core 2 613, the valve core 3 615 and the valve core 4 617, and the valve core 1 610, the valve core 2 613 and the valve core 3 615 and valve core four 617 are connected to each other through a connecting shaft 611, and the left openings of the output hole one 69, the discharge hole one 612, the discharge hole two 614 and the output hole two 616 are respectively connected to the outlet of the one-way valve one 4, the inlet of the one-way valve two 5, the inlet of the one-way valve three 9 and the outlet of the one-way valve four 10; there are two gears 63, and the two gears 63 are respectively fixedly connected to the outer central axis of the valve core one 610 and the valve core four 617; there are two pistons 67, and the two pistons 67 are respectively movably connected to the inside of the corresponding piston chamber 66, and the right sides of the two pistons 67 are fixedly connected to the rack 64, and the rack 64 is respectively connected to the corresponding gear 63, and a spring 65 is provided between the right side of the two pistons 67 and the right side of the corresponding piston chamber 66; there are two connecting pipes 68, and the left openings of the two connecting pipes 68 are respectively connected to the interior of the inner chamber one 2 and the inner chamber two 8, and the right openings of the two connecting pipes 68 are respectively connected to the left opening of the corresponding piston chamber 66.

[0017] The use state of the present utility model is as follows: the present utility model has a reasonable and simple structure, low production cost, easy installation, and complete functions. When in use, when the coolant flows from the connecting pipe 2 7 into the inner cavity 2 8, due to the action of the one-way valve 3 9 and the one-way valve 4 10, the coolant can only flow from the one-way valve 4 10 to the output hole 2 616. In addition, part of the coolant in the inner cavity 2 8 will enter the piston cavity 66 through the corresponding connecting pipe 68 to push the piston 67 and the rack 64 to move right, and the rack 64 moves right to drive the valve core 4 617 to rotate through the gear 63. When the valve core 4 617 rotates and opens, the valve core 3 615 is closed, the valve core 2 613 is opened, and the valve core 1 610 is closed through the connecting shaft 611, and then the coolant enters the liquid cooling plate inlet through the three-way pipe 11, and then the coolant after heat exchange is output to the three-way pipe 2 12 through the liquid cooling plate outlet. Since the valve core 3 615 is closed at this time, the coolant can only be transported to the inner cavity 1 2 through the opened valve core 2 613 and the one-way valve 2 5, so that it is easy to be discharged through the connecting pipe 1 3. Similarly, when the coolant is discharged from the connecting pipe 3 When flowing into the inner cavity 1-2, part of the coolant in the inner cavity 1-2 will enter the piston cavity 66 through the corresponding connecting pipe 68, pushing the piston 67 and the rack 64 to move right. The rightward movement of the rack 64 drives the valve core 1 610 to rotate and open through the gear 63. The rotation and opening of the valve core 1 610 drives the valve core 2 613 to close, the valve core 3 615 to open, and the valve core 4 617 to close through the connecting shaft 611, so that the coolant can enter the liquid cooling plate inlet through the three-way pipe 1-11, and then the coolant after heat exchange is output to the three-way pipe 2-12 through the liquid cooling plate outlet, and then the liquid cooling liquid is transported to the inner cavity 2 8 through the opened valve core 3 615 and the one-way valve 3 9, and finally the coolant is discharged through the connecting pipe 2-7. In short, no matter whether the coolant enters through the connecting pipe 1-3 or the connecting pipe 2-7, it will enter the liquid cooling plate inlet, which brings great convenience to the installation.
