Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, and in particular to a high-efficiency heat dissipation structure for lithium battery modules. Background Technology

[0002] A lithium battery module is a power source formed by connecting several individual battery cells in series and parallel through conductive connectors. It is fixed in the designed position through process and structure, and works together to perform the functions of charging, discharging and storing electrical energy.

[0003] The current method of placing lithium batteries typically involves placing them in close contact with each other, which results in poor ventilation and low heat dissipation efficiency, thus affecting the normal use of the lithium batteries. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly efficient heat dissipation structure for lithium battery modules.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency heat dissipation structure for a lithium battery module includes a frame and multiple lithium battery bodies. A top plate is installed on the top of the frame via a detachable connecting component. Multiple partitions are fixedly connected to the bottom inner wall of the frame. Multiple first through holes and multiple second through holes are respectively opened on the side of the partitions. Multiple strip holes are opened on the outer side of the partitions. Cooling pipes are fixedly connected inside the partitions, and both ends of the cooling pipes pass through the second through hole at the top.

[0007] As a further embodiment of this utility model, the connecting assembly includes multiple fixing blocks, which are respectively fixed to the outer walls of both sides of the frame by bolts. A rotating rod is movably connected to the top of the fixing block. A clearance groove is provided at multiple corners of the top plate. The top of the rotating rod passes through the clearance groove and is fixedly connected to a locking block.

[0008] As a further improvement of this utility model, a plurality of limiting blocks are fixedly connected to the bottom inner wall of the frame, and the limiting blocks are in contact with the lithium battery body.

[0009] As a further embodiment of this utility model, a pressure frame is fixedly connected to the bottom inner wall of the top plate, and the bottom of the pressure frame is in contact with the lithium battery body.

[0010] As a further embodiment of this utility model, the top of the top plate is provided with multiple slots, and a cooling fan is fixedly connected in the slot.

[0011] As a further improvement of this invention, the clearance groove can accommodate the passage of the locking block.

[0012] As a further embodiment of this utility model, the bottom of the card block is fixedly connected to an anti-slip pad, and the anti-slip pad is in contact with the top plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By using the partitions and cooling pipes together, the lithium batteries are separated from each other while achieving efficient heat dissipation. At the same time, ventilation is provided between adjacent lithium battery bodies, avoiding the problem of low heat dissipation efficiency caused by multiple lithium battery bodies being in close contact, which would affect the normal use of the lithium batteries and improve the performance of the device.

[0015] 2. By using the limit block and the spacer together, not only can the position of the lithium battery body be blocked, but it can also facilitate the positioning and installation of the lithium battery body by the staff. At the same time, the pressure frame can restrict the position of the top of the lithium battery body, thereby improving the stability of the lithium battery body.

[0016] 3. The combination of the locking block and the clearance groove makes it easy for workers to quickly disassemble and install the top plate and the frame. The operation is simple and reduces the disassembly and assembly time of the device. Attached Figure Description

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0023] Reference Figures 1-4 A high-efficiency heat dissipation structure for a lithium battery module includes a frame 4 and multiple lithium battery bodies 6. A top plate 2 is installed on the top of the frame 4 via a detachable connecting component. The top plate 2 is placed on top of the frame 4 and fixed to the frame 4 via the connecting component. Multiple partitions 14 are fixed to the inner wall of the bottom of the frame 4 by bolts. Multiple first through holes 13 and multiple second through holes 15 are respectively opened on the side of the partitions 14. Multiple strip holes 12 are opened on the outer side of the partitions 14. Cooling pipes 16 are fixed to the inside of the partitions 14 by bolts, and the two ends of the cooling pipes 16 pass through the second through holes 15 at the top. The first through holes 13, strip holes 12 and second through holes 15 allow ventilation between adjacent lithium battery bodies 6. The cooling pipes 16 are connected to an external water source through pipes, allowing external cooling water to enter the cooling pipes 16 and flow, so that the heat inside the frame 4 is carried away.

[0024] In this utility model, it should be noted that the connecting assembly includes multiple fixing blocks 10, which are respectively fixed to the outer walls of both sides of the frame 4 by bolts. A rotating rod is rotatably connected to the top of each fixing block 10. Multiple corners of the top plate 2 are provided with clearance grooves 11. The top end of the rotating rod passes through the clearance groove 11 and is welded with a locking block 9. The top plate 2 is placed on top of the frame 4, allowing the locking block 9 to pass through the clearance groove 11. Then, the locking block 9 is rotated to change its position from horizontal to vertical. At this time, both ends of the locking block 9 contact the top plate 2. Multiple limiting blocks 5 are fixed to the inner wall of the bottom of the frame 4 by bolts, and the limiting blocks 5 contact the lithium battery body 6, thus securing multiple lithium batteries. The battery body 6 is placed inside the frame 4, so that the limiting block 5 and the partition 14 block the position of the lithium battery body 6. The bottom inner wall of the top plate 2 is fixed with a pressure frame 3 by bolts, and the bottom of the pressure frame 3 is in contact with the lithium battery body 6. The pressure frame 3 can restrict the position of the top of the lithium battery body 6. The top of the top plate 2 has multiple slots 7. The slots 7 are fixed with a cooling fan 1 by bolts. The rotation of the cooling fan 1 further reduces the heat in the frame 4. The clearance slot 11 can accommodate the passage of the locking block 9. The bottom of the locking block 9 is bonded with an anti-slip pad 8, and the anti-slip pad 8 is in contact with the top plate 2. The anti-slip pad 8 can increase the friction between the locking block 9 and the top plate 2.

[0025] Working principle: In use, firstly, multiple lithium battery bodies 6 are placed inside the frame 4, so that the limiting block 5 and the partition 14 block the position of the lithium battery bodies 6. Then, the top plate 2 is placed on the top of the frame 4, so that the locking block 9 passes through the clearance groove 11. Then, the locking block 9 is rotated so that it changes from a horizontal state to a vertical state. At this time, the two ends of the locking block 9 are in contact with the top plate 2. At the same time, the first through hole 13, the strip hole 12 and the second through hole 15 allow ventilation between adjacent lithium battery bodies 6. The cooling pipe 16 is connected to an external water source through a pipe, so that external cooling water enters the cooling pipe 16 and flows, so that the heat inside the frame 4 is carried away. At the same time, the cooling fan 1 is started, thereby efficiently reducing the heat inside the frame 4.
