DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Embodiment 1

[0026] Please refer to Figures 1 - 5 , a high-temperature aging device for a modular energy storage converter, which includes an aging box body 1. An energy storage converter body 2 is placed inside the aging box body 1. One side of the energy storage converter body 2 is provided with a converter air inlet grid plate 3. Inside the aging box body 1, there is a supporting unit 4 that can be pulled out of the aging box body 1. The energy storage converter body 2 is suspended inside the aging box body 1 through the supporting unit 4. One side of the aging box body 1 is provided with a baffle 5 that can be opened and closed. A number of air inlet holes 6 are penetrated through the baffle 5. On the side of the aging box body 1 away from the baffle 5, there is an air outlet 7 communicating with the inside of the aging box body 1. An electric air valve 8 is provided on the air outlet 7, and the electric air valve 8 can adjust the air output volume of the air outlet 7. Inside the aging box body 1, there are upper and lower symmetric mounting plates 9, and a number of temperature measuring devices 10 are fixedly installed on the mounting plates 9.

[0027] The specific implementation method in this embodiment: Heat insulation materials are laid around the inside of the aging box body 1, aiming to avoid the heat transfer of high-temperature gas to the aging box body 1 and interfere with the temperature environment inside the aging box body 1. The energy storage converter body 2 is equipped with a cooling fan by itself. The cooling fan takes in air through the converter air inlet grid plate 3. When the cooling fan inside the energy storage converter body 2 works, the outside air will enter the inside of the aging box body 1 through the air inlet holes 6 and enter the internal heat dissipation channel of the energy storage converter body 2 through the converter air inlet grid plate 3. Then, after being heated up by the radiator fins, it flows into the external environment through the air outlet 7 on one side of the aging box body 1. When the temperature measuring device 10 arranged inside the aging box body 1 detects that the temperature inside the aging box body 1 is too low, the main controller will control the air output volume of the air outlet 7 through the electric air valve 8. At the same time, under the action of the fan in the heat dissipation channel inside the energy storage converter body 2, more high-temperature gas will flow back from above and below the energy storage converter body 2 to the side close to the baffle 5. The high-temperature gas is mixed with the fresh air and flows through the air duct of the energy storage converter body 2 again. At this time, the air temperature will be raised again. After being adjusted by the electric air valve 8 multiple times, the return air temperature is finally stabilized within a certain high-temperature range, creating a high-temperature aging environment close to a high-temperature enthalpy difference laboratory for the energy storage converter body 2. By combining the cooling fan of the energy storage converter body 2 with the electric air valve 8 to divert the high-temperature outlet gas to the converter air inlet grid plate 3, a high-temperature aging environment is created. Through the above device, no additional electric energy is consumed beyond the normal startup test requirements, greatly saving electricity.

[0028] It is worth noting that if it is necessary to conduct aging tests on multiple energy storage converter bodies 2 at the same time, several aging box bodies 1 can be arranged side by side, which occupies a small area in the factory building and greatly improves the aging experiment efficiency.

[0029] Among them, the electric air valve 8 mentioned above can be purchased on the market and can adjust the air volume of the air outlet 7. It belongs to a mature technology and has been fully disclosed. Therefore, it will not be repeated in the specification. The electric air valve 8 is equipped with a power connection line, and it is electrically connected to the external main controller and the 220V single-phase voltage (or 380V line voltage) through the power cord. And the main controller can be a conventional known device such as a computer that plays a control role.

[0030] Embodiment 2

[0031] Please refer to Figures 2 - 5 , this embodiment includes the above embodiment. Among them, the supporting unit 4 includes movable bearing plates 11 that are arranged symmetrically inside the aging box body 1. The two movable bearing plates 11 are fixedly installed on one side of the baffle 5. Opposite side walls inside the aging box body 1 are both provided with moving grooves 12 that are adapted to one side of the movable bearing plate 11. One side of the movable bearing plate 11 is provided with a bracket 13 in an L shape. The energy storage converter body 2 is placed between the two brackets 13. Symmetric adjusting seats 17 are provided on one side of each movable bearing plate 11. A lead screw 14 is arranged between the two adjusting seats 17. A moving block 15 is fixedly installed on the lower side surface of the bracket 13. The lead screw 14 passes through the moving block 15. A first limiting ring 16 is threadedly connected to the side surface of the lead screw 14. A sliding groove 18 is provided in the adjusting seat 17. A sliding block 20 that is adapted is slidably connected in the sliding groove 18. An adjusting bolt 19 is rotatably connected in the sliding groove 18. The upper end of the adjusting bolt 19 passes through the upper end of the adjusting seat 17 and extends to the outside. The adjusting bolt 19 passes through the sliding block 20 and is threadedly connected to the sliding block 20. A second limiting ring 21 is threadedly connected to the side surface of the upper end of the adjusting bolt 19.

[0032] Specific implementation method in this embodiment: When it is necessary to conduct an aging test on the energy storage converter body 2, by pulling the baffle 5, the side of the movable bearing plate 11 moves in the moving groove 12. A part of the two movable bearing plates 11 moves outside the aging chamber body 1. According to the volume of the energy storage converter body 2, the position of the lifting frame 13 in the vertical height direction is adjusted to ensure that the energy storage converter body 2 is located in the middle of the aging chamber body 1. During adjustment, the adjusting bolt 19 is rotated. When the adjusting bolt 19 rotates, it drives the slider 20 to move up and down in the sliding groove 18. When the slider 20 moves, it drives the lifting frame 13 to move up and down. After the lifting frame 13 moves to the required position, the second limit ring 21 is tightened to limit and fix the position of the adjusting bolt 19. The energy storage converter body 2 is placed on the two lifting frames 13, and the first limit ring 16 is rotated. The first limit ring 16 drives the lifting frames 13 to approach each other, so that the two lifting frames 13 are pressed against the side of the energy storage converter body 2 to limit and fix the energy storage converter body 2. Again, through the cooperation of the movable bearing plate 11 and the moving groove 12, the energy storage converter body 2 is pushed into the aging chamber body 1, which is convenient for the operator to place the energy storage converter body 2 into the aging chamber body 1, and can limit and fix the energy storage converter body 2 of different sizes.

[0033] Embodiment III

[0034] Please refer to Figures 1 - 5 , this embodiment includes the above embodiments. Among them, it further includes: A plurality of auxiliary wheels 22 are rotatably connected to one side of the movable bearing plate 11. The plurality of auxiliary wheels 22 are adapted to the moving groove 12. A plurality of casters 23 are fixedly installed on the lower side of the aging chamber body 1. A handle 24 is fixedly installed on one side of the baffle 5.

[0035] Specific implementation method in this embodiment: By setting the handle 24, it is convenient for the operator to pull out the supporting unit 4 with the energy storage converter body 2 from the aging chamber body 1. When the movable supporting unit 4 is moved, the plurality of auxiliary wheels 22 move in the moving groove 12, reducing the friction coefficient between the movable bearing plate 11 and the aging chamber body 1. The casters 23 facilitate the operator to move the aging chamber body 1.
