[0002] Energy storage cells generally refer to new energy batteries. These cells are typically composed of lithium iron phosphate or ternary batteries, and they provide sufficient power for electric vehicles to operate. As battery energy density continues to increase, the heat generated by these cells during operation increases significantly. Traditional heat dissipation methods struggle to effectively remove this heat, leading to excessively high cell temperatures, which in turn affects battery performance, lifespan, and even safety.

The utility model is provided with an air cooling device, and when performing heat dissipation operations on multiple groups of limit slots, the upper and lower four groups of air coolers can synchronously guide air, so that the four groups of air coolers located at the upper part can guide air at high speed through the air guide holes, and at the same time, the four groups of air coolers located at the lower part can perform high-speed exhaust, thereby maximizing the efficiency of the equipment in extracting heat from the battery cell shell, and at the same time, multiple groups of heat dissipation fins can quickly dissipate the extracted heat energy, effectively improving the efficiency of the equipment in dissipating heat from the battery cell shell.

[0004] The above-mentioned battery cell heat dissipation methods mainly rely on natural heat dissipation or simple air cooling systems. These methods are inadequate when dealing with battery cells with high power density and high charge and discharge rates. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0017] Compared with the existing technology, the beneficial effects of the present invention are:

[0018] 1. In this dynamic temperature-controlled battery cell heat dissipation structure, a double-layer structure of a protective bottom cover and a removable top cover is provided, and the connection slot and the removable top cover are plugged together to form a well-sealed protective space, effectively isolating external electromagnetic interference and protecting the stable operation of internal electronic products. The built-in drying box has a mesh shell design that allows air circulation, while the drying material filled inside can effectively absorb and remove water vapor in the protective space, preventing electronic products from being damaged by a humid environment and extending the service life of the product.

[0034] Dynamic temperature control of the battery cell heat dissipation structure, such as Figure 1-Figure 3 As shown, it includes a battery cell mounting seat 20 for mounting several groups of battery cells, a top heat dissipation box 10 is installed on the top surface of the battery cell mounting seat 20, a bottom heat dissipation seat 30 is provided at the bottom of the battery cell mounting seat 20, and a control box 40 and a battery 50 are installed on the outer wall of the top heat dissipation box 10; the top heat dissipation box 10 is communicated with the battery cell mounting seat 20, and a cooling fan 12 is installed in the top heat dissipation box 10; a temperature sensor 21 is installed at the center of the top surface of the battery cell mounting seat 20; a semiconductor refrigerator 31 is installed in the bottom heat dissipation seat 30, and the top surface of the semiconductor refrigerator 31 is embedded in the bottom of the battery cell mounting seat 20, the top heat dissipation box 10 is tightly connected to the battery cell mounting seat 20, and the built-in cooling fan 12 effectively enhances the air convection on the top of the battery cell, accelerates the heat dissipation, and avoids the performance degradation or damage of the battery cell due to overheating. The temperature sensor 21 is precisely installed at the center of the top surface of the battery cell mounting seat 20, and can monitor the working temperature of the battery cell in real time, providing key data support for dynamic temperature control. The semiconductor cooler 31 integrated within the bottom heat sink 30 has its top surface embedded directly into the bottom of the battery cell mounting base 20, enabling direct cooling of the bottom of the battery cell. The semiconductor cooler's efficient cooling capacity, combined with a dynamic temperature control strategy, can rapidly reduce the battery cell temperature when it becomes too hot, ensuring safety and stable performance. The synergistic effect of the control box 40 and battery 50 provides a stable and reliable power supply and intelligent control for the entire cooling system. Adjusting the operating intensity of the cooling fan and semiconductor cooler enables precise control of the battery cell temperature.

[0035] Furthermore, a dustproof net 11 is installed on the top surface of the top heat dissipation box 10, which effectively blocks the entry of external dust and impurities and keeps the interior of the heat dissipation system clean.

[0036] Specifically, the control box 40 has a built-in control panel, which is equipped with a single-chip microcomputer 41. The output port of the temperature sensor 21 is connected to the input port of the single-chip microcomputer 41, enabling real-time and accurate acquisition of battery cell temperature data, which is then rapidly processed by the single-chip microcomputer 41. The efficient computing power of the single-chip microcomputer 41 ensures that the system can quickly respond to temperature changes, providing a reliable basis for subsequent heat dissipation control.

[0037] The single chip microcomputer 41 is an AT89S52 single chip microcomputer, and the temperature sensor 21 is a DS18B20 temperature sensor.

[0038] It is worth noting that the output end of the single-chip microcomputer 41 is connected to the electromagnetic switch 42 for controlling the switching of the cooling fan 12 and the semiconductor refrigerator 31. A temperature display screen 43 for displaying the temperature inside the battery cell mounting seat 20 is installed on the outer wall of the control box 40. The output end of the single-chip microcomputer 41 is connected to the input end of the temperature display screen 43. According to the data feedback from the temperature sensor 21, the single-chip microcomputer 41 can intelligently judge and control the on and off of the electromagnetic switch 42, thereby adjusting the speed of the cooling fan 12 and the working status of the semiconductor refrigerator 31 to ensure that the battery cell temperature fluctuates within a reasonable range; the temperature display screen 43 can display the temperature inside the battery cell mounting seat 20 in real time, providing an intuitive and convenient monitoring means for the operator.

[0039] In addition, the cooling end of the semiconductor cooler 31 is provided with an insulating ceramic sheet, and the insulating ceramic sheet is embedded in the bottom surface of the battery cell mounting base 20. The insulating ceramic sheet has good insulation and thermal conductivity, which can effectively isolate the current and ensure that heat is transferred from the battery cell to the semiconductor cooler 31. The cooling principle of the semiconductor cooler 31 is as follows: Figure 4 shown.

[0040] The working principle of this dynamic temperature-controlled battery cell heat dissipation structure: the operator installs the battery cell in the battery cell mounting seat 20 according to the design requirements, the temperature sensor 21 monitors the battery cell temperature in the center area of the top surface of the battery cell mounting seat 20 in real time, and transmits the data to the control box 40. The control box 40 analyzes the current battery cell temperature status according to the preset temperature threshold and dynamic temperature control strategy. If the battery cell temperature is normal, the cooling fan 12 is maintained at a lower speed to maintain air circulation. At the same time, the semiconductor cooler 31 is in standby or low power consumption state. If the battery cell temperature exceeds the preset high temperature threshold, the control box 40 will automatically adjust the cooling fan 12 to high speed to enhance the top air convection, and at the same time start the semiconductor cooler 31 to quickly cool the bottom of the battery cell until the battery cell temperature drops back to a safe range.
