Description

Technical Field

[0001] The utility model relates to the technical field of battery components, in particular to a single-glass TOPCON battery component. Background Art

[0002] The TOPCON cell structure is an N-type silicon substrate cell. First, an ultra-thin layer of silicon oxide is prepared on the back of the cell, and then a thin layer of doped silicon is deposited. The two together form a passivated contact structure, which effectively reduces surface recombination and metal contact recombination, and provides greater space for further improvement of the photoelectric conversion efficiency of the N-PERT cell. TOPCON cells can be divided into single-glass TOPCON cells and double-glass TOPCON cells according to their interlayer structure.

[0003] Existing battery modules usually require brackets and bolts during installation. The combination of brackets and bolts requires the use of professional auxiliary tools during installation, and the installation efficiency is slow. The subsequent disassembly and maintenance are cumbersome, and it is not convenient to protect the corners of the battery modules after installation, resulting in them being exposed and easily damaged.

[0004] To this end, we propose a single-glass TOPCON battery module. Utility Model Content

[0013] Beneficial effects of the utility model:

[0014] 1. The TOPCON solar panel can be installed and positioned by cooperating with the positioning block 1.

The outer edge of the latch 8 is fixedly connected with a disc 19, and the outer side of the disc 19 is fixedly connected with a return spring 10. TOPCON solar panels 12 are installed on the inner walls of the two positioning blocks 13 and the two positioning blocks 2 6. A hot and cold converter 15 is fixedly installed on the inner wall of the storage box 13. A circulating pump 16 is fixedly installed on the inner wall of the storage box 13. The output end of the circulating pump 16 is fixedly connected to one end of a connecting pipe 17, and the other end of the connecting pipe 17 is fixedly connected to a temperature conducting block 18. The inner wall of the temperature conducting block 18 is fixedly connected to a transfer pipe 19.

[0024] See also Figure 2 The end of the return spring 10 away from the disc 1 9 is fixedly connected to the disc 2 11, and the disc 2 11 is slidably connected to the outer edge of the latch 8. The latch 8 is arranged in the middle position of the return spring 10, so that the end of the return spring 10 away from the disc 1 9 can be limited when the force is reset, ensuring that the return spring 10 will not contact and rub against the inner wall of the protective cover 7, and when the latch 8 is pulled, the disc 1 9 can squeeze the return spring 10 to bear the force, thereby facilitating reset during subsequent installation.

[0025] See also Figure 2 A through hole is provided on the outside of the frame 1, and the through hole extends to the inner wall of the block 5. The latch 8 is slidably connected to the inner wall of the through hole. A handle is fixedly installed on the end of the latch 8 away from the block 5, so that the block 5 can be stably positioned on the inner wall of the square groove 4 through the latch 8, thereby realizing the installation of the positioning block 2 6, ensuring that the positioning block 2 6 can be stably installed at the top position of the frame 1, and the position of the latch 8 can be easily adjusted by pulling the handle, so that the end of the latch 8 close to the block 5 can be moved away from the inner wall of the block 5.

[0026] See also Figure 1 and Figure 2 Four support rods 2 are symmetrically fixed on the bottom of the frame 1, and the bottoms of the four support rods 2 are provided with anti-slip grooves, so that the device can be stably placed at the location where it needs to be installed, and the anti-slip grooves can ensure that it will not be easily displaced after placement.

[0027] See also Figure 3 and Figure 4The inner wall of the storage box 13 is threadedly connected to a sealing cover 14, the inner wall of the sealing cover 14 is connected to a water supply pipe, and an electromagnetic valve is fixedly installed on the inner wall of the water supply pipe, so that the sealing cover 14 can be used to seal the top of the storage box 13 to ensure that foreign matter from the outside does not enter its interior. The water supply pipe can be used to supplement water when the water source in the inner cavity of the storage box 13 is insufficient.

[0028] See also Figure 4 and Figure 5 There are four temperature conducting blocks 18, and the four temperature conducting blocks 18 are distributed in a ring shape on the outer edge of the transfer pipe 19. The connecting pipe 17, the four temperature conducting blocks 18 and the transfer pipe 19 are all connected. The inner cavity of the storage box 13 is filled with water. The storage box 13 is installed on the top of the bottom plate 21. The tops of the four temperature conducting blocks 18 are all in contact with the bottom of the TOPCON solar panel 12, so that the water heated and cooled in the inner cavity of the storage box 13 through the heat converter 15 can be transferred to the inner cavity of the temperature conducting block 18 by the connecting pipe 17, and then the temperature is transferred to the TOPCON solar panel 12 by the temperature conducting block 18, so that it can dissipate heat in summer and heat it in winter, so as to avoid the TOPCON solar panel 12 from being too cold, causing the electrolyte inside the battery to become viscous, and reducing the activity of the active material, resulting in slow energy conversion efficiency during charging and slow energy discharge efficiency during discharge.

[0029] Please refer to the figure - Figure 5 The inner walls of the four support rods 2 are fixedly mounted with a bottom plate 21, and the bottoms of the two symmetrically arranged temperature conducting blocks 18 are fixedly mounted with positioning pins 20, and the bottoms of the two positioning pins 20 are plugged into the tops of the bottom plates 21, so that the positioning pins 20 can be used to support the temperature conducting block 18, ensuring that the top of the temperature conducting block 18 can stably contact the bottom of the TOPCON solar panel 12. At the same time, the temperature conducting block 18 can support the middle position of the TOPCON solar panel 12 to ensure that it will not be in a suspended state, thereby improving the force effect of the TOPCON solar panel 12 and ensuring that it will not be easily damaged when impacted by external forces.

[0030] Working principle: When using the device, first install the device to the place of use, then snap one side of the TOPCON solar panel 12 to the inner wall of the two positioning blocks 1 3, and slide the block 5 to the inner wall of the square groove 4, and then snap the positioning block 2 6 to the corner of the TOPCON solar panel 12 away from the positioning block 1 3, and then use the force of the return spring 10 to push the end of the latch 8 away from the handle to insert it into the inner wall of the block 5 to position the block 5, and then complete the installation of the TOPCON solar panel 12, and the bottom of the TOPCON solar panel 12 is in contact with the top of the four temperature conducting blocks 18, and then the water in the inner cavity of the storage box 13 can be cooled or heated by the heat converter 15 according to the weather temperature, and then the circulating pump 16 can be driven to operate and the water in the inner cavity of the storage box 13 heated and cooled by the heat converter 15 is transferred to the inner cavity of the temperature conducting block 18 by the connecting pipe 17, and then the temperature is transferred to the inner cavity of the temperature conducting block 18 by the temperature conducting block 18. The temperature is transmitted to the TOPCON solar panel 12, so that it can dissipate heat in the summer and heat it in the winter, so as to prevent the TOPCON solar panel 12 from being too low in temperature, making the electrolyte inside the battery thick and the activity of the active material reduced, resulting in slow energy conversion efficiency during charging and slow energy discharge efficiency during discharge. At the same time, the temperature conducting block 18 is used in conjunction with the positioning pin 20 to support the middle position of the TOPCON solar panel 12 to ensure that it is not in a suspended state, thereby improving the force effect of the TOPCON solar panel 12 and ensuring that it is not easily damaged when impacted by external forces. By pulling the handle to drive the end of the latch 8 close to the block 5 to separate from the inner wall of the block 5, the block 5 can be slid out of the inner wall of the square groove 4, and then the connection between the TOPCON solar panel 12 and the positioning block 2 6 can be separated, so that the TOPCON solar panel 12 can be conveniently removed for inspection and maintenance, and the operation can be completed manually without the use of auxiliary tools.
