Low-speed background wind optimized vertical test piece icing device and use method thereof

The invention provides a low-speed background wind optimized vertical test piece icing device and a use method thereof, and belongs to the technical field of test piece icing devices. In order to solve the problem that the icing effect obtained when an array air atomizing nozzle directly faces a large vertical test piece to carry out a spray icing test is poor, the invention provides a set of device which is provided with an array background fan at the upstream of a spray frame, uses a cellular board and a screen to rectify low-speed background wind and assists in conveying cloud mist to enhance the icing effect. A test piece is placed in the inner space of the test chamber, a spraying frame, a screen, a cellular board and a background fan are sequentially installed in front of the test piece, an induced draft fan is installed in the front of the test chamber, an exhaust fan is installed at the rear of the test chamber, and demisters are installed on the two sides of the test piece.
