Description

Technical Field

[0002] The cooling system of a pure electric wide-body vehicle is a crucial component, playing a vital role in ensuring vehicle performance and extending its lifespan. Firstly, key components such as the battery pack and electric motor in a pure electric wide-body vehicle need to be maintained within a suitable operating temperature range to guarantee vehicle performance and lifespan. The battery pack generates a significant amount of heat during operation; if not dissipated promptly, this can lead to performance degradation and even safety hazards. Therefore, pure electric wide-body vehicles require an efficient cooling system to dissipate the heat generated by the battery pack effectively. Secondly, the electric motor in a pure electric wide-body vehicle also generates considerable heat during operation. If not dissipated promptly, this can affect the motor's performance and lifespan, and may even cause it to burn out. Therefore, pure electric wide-body vehicles also need an electric motor radiator to dissipate the heat generated by the electric motor effectively.

[0003] In response to the aforementioned technologies, pure electric wide-body vehicles need to be equipped with a high-efficiency cooling system to dissipate heat from the battery pack and electric motor, thereby preventing damage to the components of the pure electric wide-body vehicle during operation.
