[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 A heat dissipation structure for an aircraft battery includes an air-cooled bracket 1, which is formed using a two-color injection molding process. An air-collecting housing 2 is provided inside the air-cooled bracket 1. Multiple cell housings 3 are provided inside the air-collecting housing 2. The multiple cell housings 3 are connected to each other through plastic connection points 4. An airflow channel 5 is formed between the multiple cell housings 3. The multiple cell housings 3 and the air-collecting housing 2 are connected through plastic connection points 4 to form a cell housing group. A cell 6 is nested inside the cell housing 3.

[0020] The current collector housing 2 is made of plastic material using injection molding process and has low thermal conductivity; the current collector housing 2 is a housing that wraps around the battery cell housing assembly and has a through structure at the top and bottom.

[0021] The battery cell housing 3 is made of aluminum material using an aluminum extrusion process, and has high thermal conductivity. The battery cell housing 3 is cylindrical with a through-hole structure at the top and a battery cell 6 support structure at the bottom.

[0022] An insulating thermally conductive pad 7 is also provided between the battery cell 6 and the battery cell housing 3.

[0023] The air-cooled bracket 1 is a cube with a through structure at the top and bottom; an exhaust fan is also installed on the air-cooled bracket 1.

[0024] Working principle: By installing the battery cell 6 inside the battery cell housing 3, when the battery cell 7 dissipates heat, the airflow channel 5 structure designed between the aluminum battery cell housing 3 and the plastic current collector housing 2 allows the heat generated by the battery cell 6 to be quickly conducted to the aluminum battery cell housing 3 and discharged through the airflow channel 5. Furthermore, the plastic connection point 4 effectively insulates against heat transfer to the adjacent aluminum battery cell housing 3, preventing heat spread between the battery cells 6 and potential power reduction or other dangerous situations. Simultaneously, the installed exhaust fan accelerates airflow through the airflow channel 5, speeding up heat dissipation.
