Description

Technical Field

[0001] The utility model relates to the technical field of energy storage batteries, in particular to a thermal balance device for an energy storage battery. Background Art

[0002] An energy storage battery is a device that can store electrical energy in the form of chemical energy and convert the chemical energy back into electrical energy when needed. The battery generates heat during the charging and discharging process. When the temperature is too high, the chemical reaction rate inside the battery will accelerate, reducing the battery's charging and discharging efficiency and reducing the use effect of the energy storage battery.

[0003] A search revealed patent document CN221176398U, which discloses a thermal balancing device for energy storage batteries in rural power distribution systems. This device uses a resistor in series to divide the voltage across a temperature sensor and employs an analog-to-digital converter (ADC) to convert analog signals into digital signals. The heating drive circuit uses a TC1412N dual-channel driver chip, with MOS transistors used as switching elements. The heating power is adjusted by controlling the duty cycle of the MOS driver signal. The LMD18200 chip is used to control the fan and blinds. By controlling the duty cycle of the input PWM signal, the fan speed can be controlled and the blinds can be switched on and off.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] The embodiment of the utility model discloses a thermal balance device for an energy storage battery.

[0032] Example 1

[0033] The utility model provides Figure 1-5 The thermal balance device for an energy storage battery shown includes a housing 1 and an energy storage battery 2 disposed within the housing 1. An air inlet is formed on one side of the housing 1. A filter 3 is provided on the outer cover of the air inlet. Mounting bolts 7 are threadedly passed through both ends of the outer side of the filter 3. The mounting bolts 7 are screwed and fixed to the outer side of the housing 1. A cooling fan 4 is fixedly disposed on one side of the inner side of the housing 1.

[0034] A plurality of heat exchange holes are provided at intervals on the other side of the shell 1. A support rod 24 is fixed to the upper end of the inner wall of the heat exchange hole. A swing leaf 5 is rotatably sleeved on the rod wall of the support rod 24. A sealing gasket 23 is fixed to the top of the swing leaf 5. The sealing gasket 23 contacts and cooperates with the top of the inner wall of the heat exchange hole. A protective cover 6 is provided on the lower side of the swing leaf 5. The protective cover 6 is in the form of a mesh cover, and the outer wall contacts and cooperates with the inner wall of the heat exchange hole.

[0035] When the energy storage battery is in use, when the frequency of battery use increases, the swing leaf 5 can be rotated under the support of multiple support rods 24. At this time, under the connection between the swing leaf 5 and the protective cover 6, the heat exchange hole is opened, and the cooling fan 4 is started to draw external air into the outer shell 1, and effectively cool down and exchange heat for the energy storage battery. During the gas flow process, the dust in the air flow is first blocked by the filter 3 and cannot enter the outer shell 1. At the same time, when the protective cover 6 is opened, the protective cover 6 fits tightly with the inner wall of the heat exchange hole. At the same time, the protective cover 6 is set as a mesh cover, which can not only ensure the stable flow of the airflow, but also block external dust, and try to avoid blocking the dust from entering the outer shell 1 and covering the battery surface, thereby ensuring the stable use of the energy storage battery.

[0036] Example 2

[0037] Example 2 is based on Example 1 in order to enable multiple swing blades 5 to be stably deployed and perform effective heat exchange work, such as Figure 1-2As shown, the lower ends of multiple protective covers 6 are provided with a winding opening and closing mechanism, which includes a pull rope 8, the lower end of the pull rope 8 is fixedly connected to the protective cover 6, and the upper end is wrapped with a winding wheel 9, and a rotating rod 10 is fixedly penetrated inside the winding wheel 9, and the end of the rotating rod 10 is rotatably matched with the inner wall of the shell 1, and internal thread grooves are provided on both sides of the protective cover 6, and an external thread guide rod 11 is penetrated by the internal thread of the internal thread groove, and guide grooves for matching the external thread guide rod 11 are provided on both sides of the inner wall of the shell 1, and a guide spring 12 is fixedly provided at the top of the inner wall of the guide groove, and an electric push rod 13 is fixedly provided at the bottom of the inner wall of the shell 1, and a vertical plate 14 is fixedly provided at the end of the output shaft of the electric push rod 13, and a plurality of racks 15 are fixed on the outer wall of the vertical plate 14, and the rack 15 is matched with a gear 16, and the gear 16 is fixedly sleeved with the rotating rod 10.

[0038] When the battery is in normal use, the protective cover 6 is pulled by the pull rope 8 and is located inside the shell 1. At this time, the swing leaf 5 does not rotate, and the guide spring 12 is squeezed at the same time. When the battery is used frequently, the electric push rod 13 is started, and the vertical plate 14 drives the multiple racks 15 to move longitudinally. During the movement of the rack 15, it engages with the gear 16, so that the gear 16 drives the rotating rod 10 to rotate. Under the support of the rotating rod 10, the winding wheel 9 rotates and loosens the pull rope 8. At this time, under the elastic force recovery of the guide spring 12, the protective cover 6 can be connected to the pull rope 8 and limited while slowly rotating, thereby pushing the swing leaf 5 to rotate and opening the heat exchange hole. At this time, the battery can perform stable heat exchange with the external airflow.

[0039] Example 3

[0040] Example 3 is based on Example 1-2 in order to facilitate the quick replacement of the protective cover 6 after long-term use. Figure 3-4 As shown, a mounting plate 17 is fixed to the upper end of the outer wall of the swing leaf 5, and a through-hole is provided on the side of the protective cover 6 to match the mounting plate 17. Two fixing plates 18 are fixed to the upper end of the outer wall of the protective cover 6. A plug rod 19 is slidably passed through the interior of the fixing plate 18. A slot for fitting the plug rod 19 is provided on the outer wall of the mounting plate 17. A pulling hole 20 is provided on the rod wall of the plug rod 19. A sliding hole is provided on the rod wall of the plug rod 19. A fixing rod 21 is slidably passed through the sliding hole. The fixing rod 21 is fixed to the interior of the fixing plate 18. A positioning spring 22 is fixed between the fixing rod 21 and the inner wall of the sliding hole. An inclined surface is provided on the outer side of the end of the plug rod 19 inserted into the slot.

[0041] When the protective cover 6 is in use, the position of the protective cover 6 can be determined by the cooperation between the mounting plate 17 and the through-hole, and the insertion of the insertion rod 19 into the slot. When the protective cover 6 needs to be replaced, the two insertion rods 19 can be pulled so that the insertion rod 19 moves and separates from the slot under the sliding guidance of the sliding hole and the fixed rod 21. At this time, the protective cover 6 can be separated from the swing leaf 5 and the replacement is completed. When the protective cover 6 is re-inserted with the mounting plate 17, the insertion rod 19 can be automatically moved and inserted into the slot under the cooperation of the inclined surface of the insertion rod 19, which reduces the installation time and improves the overall operation convenience of the device.

[0042] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
