Description

Technical Field

[0001] This utility model relates to the field of aircraft battery technology, specifically to an aircraft battery. Background Technology

[0002] The battery module is an important component of electric aircraft. During charging, discharging, and flight, the battery pack continuously discharges at a high rate, intensifying the chemical reactions inside the cells and converting a large amount of chemical energy into electrical energy. At the same time, a large amount of heat is generated. Therefore, we need to use effective means to conduct the heat of the battery pack to the external space.

[0003] Chinese utility model patents, with announcement number CN119381616A and application number CN202310934614.6, disclose a battery pack cooling system and an aircraft containing the same. The patent includes a battery box, a cover plate, coolant, and a battery pack. The cover plate is mounted on top of the battery box, and the battery box and cover plate together form a sealed space; the coolant is placed within the sealed space; the battery pack is placed inside the battery box, and the coolant is used to cool the battery pack. This method is inefficient in heat dissipation, and air cooling and liquid cooling are mutually exclusive. The liquid cooling unit increases the battery weight, affecting the overall weight and safety of the aircraft.

[0004] Therefore, we propose an aircraft battery to solve the above problems. Utility Model Content

The battery cell bracket is provided with multiple fixing slots, and the fixing slots are provided with battery cells. The top of the battery cell bracket is provided with a current collector assembly covering the battery cells. The current collector assembly is used to fix the battery cells in the fixing slots and connect the electrodes of all battery cells in the fixing slots. A fan plate is also provided on the top of the current collector assembly. The fan plate is fixedly connected to the left air duct plate, the right air duct plate, the front air duct plate and the rear air duct plate, forming a closed space with the liquid cooling plate.

[0021] Please see Figure 1-2 An aircraft battery includes a cell support 2, which serves as a carrier for placing a battery cell 3. A liquid cooling plate 1 is located at the bottom of the cell support 2, allowing the liquid flow to remove heat generated by the battery cell 3. A left air duct plate 4 and a right air duct plate 5, fixedly connected to the liquid cooling plate 1, are respectively located on the left and right sides of the cell support 2, providing protection for both sides. A heating element 8, which is a heating film, is also located between the left and right air duct plates 4 and 5 and the cell support 2. The heating element 8 heats the battery cell 3 inside the cell support 2. A front air duct plate 1 is fixedly connected to the liquid cooling plate 1 on the front and rear sides of the cell support 2. The side air duct plate 6 and the rear air duct plate 7 protect the front and rear sides of the battery cell bracket 2. The battery cell bracket 2 is provided with multiple fixing slots, and the fixing slots are provided with battery cells 3. The top of the battery cell bracket 2 is provided with a current collector 9 covering the battery cells 3. The current collector 9 is used to fix the battery cells 3 in the fixing slots and connect the electrodes of all the battery cells 3 in the fixing slots. The top of the current collector 9 is also provided with a fan plate 10. The fan plate 10 is fixedly connected to the left air duct plate 4, the right air duct plate 5, the front air duct plate 6 and the rear air duct plate 7, forming a closed space with the liquid cooling plate 1. The fan plate 10 is also provided with an air cooling component 11 for air cooling the battery cells.

[0022] A fixing bracket is provided on both the left air duct plate 4 and the right air duct plate 5. A fixing slot is provided on both the left and right sides of the battery cell bracket 2. The fixing bracket is inserted into the fixing slot and connected by bolts. In this way, the left air duct plate 4 and the right air duct plate 5 can be fixed without affecting the installation of the heating element 8 and the air flow.

[0023] Both the front air duct plate 6 and the rear air duct plate 7 are equipped with a second fixing bracket. The battery cell bracket 2 is equipped with a second fixing slot on both the left and right sides. The second fixing bracket is inserted into the second fixing slot and connected by bolts. This arrangement can fix the front air duct plate 6 and the rear air duct plate 7 without affecting the air flow. The air-cooling component 11 is a fan. The air-cooling component 11 is fixed to the top or bottom of the fan plate 10 by bolts. The air-cooling component 11 generates air flow, thereby removing the heat generated by the battery cell 3.

[0024] The liquid cooling plate 1 is also provided with cold plate airflow holes, and the liquid cooling plate 1 is also provided with liquid inlet and liquid outlet. By opening the cold plate airflow holes, the airflow inside the cell bracket 2 can be increased. The cell bracket 2 is also provided with bracket airflow holes around its perimeter. By opening the bracket airflow holes, the airflow inside the cell bracket 2 can be increased.

[0025] The current collector 9 is also provided with a current collector airflow hole, which can increase the airflow inside the cell support 2; the fan plate 10 is also provided with a fan plate airflow hole, which can increase the airflow inside the cell support 2; the current collector airflow hole and the fan plate airflow hole are corresponding to each other, which can prevent the current collector airflow hole and the fan plate airflow hole from being blocked and affecting the airflow inside the cell support 2.

[0026] Working principle: Heating: When the temperature is too low and affects the battery's charging and discharging efficiency, the battery needs to be heated during charging and discharging. This is achieved by heating films on both sides, so that cell 3 can reach the optimal charging and discharging temperature.

[0027] Air cooling: Due to the small airflow holes designed between the battery cell bracket 2 and the air duct plate, the airflow is turbulent by the fan fixed on the fan plate, so that the airflow passes through the airflow holes of the liquid cooling plate and the airflow holes of the surrounding air duct plate to achieve air cooling heat dissipation. This heat dissipation method is only used during aircraft operation.

[0028] Liquid cooling: The bottom of the cell support 2 is designed with a liquid cooling plate 1 to achieve radial and efficient heat dissipation of the cylindrical cell 3. This liquid cooling method is only used when the battery is being charged at the battery swapping station. During the operation of the aircraft, the liquid cooling plate 1 does not work. This measure reduces the number of devices on the aircraft and lowers the overall weight and safety risk index.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
