撰写专利主权项摘要

Principal independent claim (Claim 1) — summary:

The claim is directed to a battery-pack thermal management system comprising:

• A heat-exchange loop that includes a cooling medium and a circulation pump;
• A temperature-sensor array disposed proximate to multiple battery cells; and
• A controller operably coupled to the temperature-sensor array and the circulation pump, configured to:
  • increase the pump flow rate when the temperature of any cell exceeds a first threshold;
  • decrease the pump flow rate when the temperature is below a second threshold; and
  • select among different cooling modes based on vehicle operating conditions.

主权项（权利要求1）概述与要点如下：

• 标的物：一种用于无人机螺旋桨叶片的降噪结构。
• 必要技术特征：
  1. 叶片尾缘设置锯齿形边缘，其中：
     • 齿高H为叶弦长的1%—4%；
     • 齿距P为叶弦长的4%—12%。
  2. 叶尖设置微小翼，翼展为叶长的0.5%—2%。
• 功能性限定：上述锯齿形尾缘与叶尖微小翼相互配合，以降低宽带涡噪。

该独立权利要求以具体的几何参数范围对尾缘锯齿及叶尖微小翼进行限定，并以二者的协同降噪作用作为功能性效果限定，构成完整的技术方案。
