A supercooled large water drop detector can accurately and reliably identify and distinguish freezing weather of supercooled large water drops. The supercooled large water drop detector comprises a detector base and a detection structure, the detection structure is used for detecting supercooled water drops in airflow and identifying and distinguishing the freezing weather of the supercooled large water drops from the freezing weather, the outer layer of the detection structure is a temperature sensor layer, the middle layer of the detection structure is an electric heating film layer, and the inner layer of the detection structure is a structure base. The electric heating film layer provides heating energy through a plurality of electric heating loops, so that the surface of the detection structure is kept at a uniform temperature, the temperature sensor layer is provided with a plurality of temperature sensors, and a controller is arranged in the structure substrate; the controller deduces the impact range of the supercooled water drops through temperature changes of multiple different positions caused when the supercooled water drops impact the detection structure, and determines whether the previously impacted supercooled water drops are supercooled large water drops or not by judging whether the impact range exceeds a critical impact range when the supercooled water drops of critical dimensions impact the detection structure or not.

    一种过冷大水滴探测器,能够准确且可靠地识别并区分过冷大水滴结冰气象。过冷大水滴探测器包括探测器基座和探测结构,探测结构用于检测气流中的过冷水滴并用于识别并从结冰气象中区分出过冷大水滴结冰气象,探测结构的外层为温度传感器层,中间层为电加热膜层,内层为结构基底,电加热膜层通过多个电加热回路来提供加热能量,使得探测结构的表面保持为均匀的温度,温度传感器层具有多个温度传感器,在结构基底中设置有控制器,控制器通过过冷水滴撞击探测结构所引起的多个不同位置的温度变化来推断出过冷水滴的撞击范围,并通过判断撞击范围是否超出临界尺寸的过冷水滴撞击探测结构时的临界撞击范围,来确定先前撞击的过冷水滴是否为过冷大水滴。
