The supercooled water spraying part is provided with a spray heating layer inside the bottom surface of the supercooled water box.

The airflow in the test box is in a state of circulation through the circulating wind generator, so that the airflow continuously passes through the heater and evaporator, so that the inside of the test box reaches the required temperature and humidity conditions. Through the stirring mechanism, the pure water stored in the supercooled water box is in a state of circulating flow, and continuously passes through the water condenser, so as to control the water temperature within the range of ±1°C. The supercooled water is sprayed onto the samples in the test chamber through the supercooled water spraying unit, so as to realize the simulation of freezing rain. Wherein, the effect of spraying the heating layer is to prevent supercooled water from freezing in the supercooled water box thereby blocking the parts in the supercooled water box.

In a preferred embodiment, the inner part of the test box is a test area and an equipment installation area, and the circulating wind generator, heater and evaporator are arranged in the equipment installation area. The purpose is to ensure that the internal space of the test box is fully utilized.

In a preferred embodiment, the water accumulation tray is provided with accumulation water discharge holes. When there is too much accumulated water on the water accumulation tray, the accumulated water can be discharged by opening the accumulation water discharge hole, which avoids the trouble of taking out the accumulation water tray for drainage.

In a preferred embodiment, the stirring mechanism is composed of a motor arranged outside the supercooled water box and a rotating blade arranged inside the supercooled water box, and the output shaft of the motor extends to the inside of the supercooled water box to connect with the rotating blade. This setting can ensure that the stirring mechanism can work stably.

In a preferred embodiment, the supercooled water spraying member is an atomizing nozzle, which is evenly distributed on the bottom surface of the supercooled water box. It can effectively spray supercooled water evenly on the samples in the test chamber.

In a preferred embodiment, the spray heating layer is a heating wire distributed inside the bottom surface of the supercooled water box. The setting of the heating wire is more convenient, and the process is also relatively simple.
