Summary of the invention
Based on this, for the problems referred to above, the present invention proposes a kind of nozzle that can effectively prevent and freezes and can make test effect reach the accumulated ice sleet testing equipment of optimum condition.
Technical scheme of the present invention is: a kind of accumulated ice sleet testing equipment, comprise the test casing and be located at the subcooled water box of testing the casing top, be provided with successively from top to bottom recirculating air generating means, well heater and evaporator in the described test casing, bottom in the described test casing is provided with water accumulating disc, be provided with water condenser and rabbling mechanism in the described subcooled water box, the bottom surface of described subcooled water box is provided with the subcooled water spraying pack unit that communicates with described test box house, is provided with the sprinkling zone of heating in the inside of described subcooled water box bottom surface.
Make the air-flow in the test casing be in a state that circulates by the recirculating air generating means, air-flow is constantly passed through from well heater and evaporator, thereby make the test box house reach desired temperature, damp condition.Make the pure water that is stored in the subcooled water box be in the state that circulates by rabbling mechanism, and constantly pass through water condenser, thus reach water temperature is controlled at ± 1 ℃ scope in.Subcooled water is sprayed onto on the interior sample of test casing through the subcooled water spraying pack unit, thereby realizes that sleet occurs in simulation.Wherein, thus the effect of spraying zone of heating is to stop up parts in the subcooled water box for prevent that subcooled water from freezing in the subcooled water box.
In a preferred embodiment, described test box house is divided into test site and equipment installing zone, and described recirculating air generating means, well heater and evaporator are located at the equipment installing zone.Purpose is to be fully used in warranty test box house space.
In a preferred embodiment, described water accumulating disc is provided with the ponding discharge orifice.When the ponding on the water accumulating disc is too much, can ponding be discharged by opening the ponding discharge orifice, avoided taking out the trouble of water accumulating disc draining.
In a preferred embodiment, described rabbling mechanism is comprised of the motor of being located at subcooled water box outside and the rotating vane of being located at subcooled water box inside, and the output shaft of described motor extends to subcooled water box inside and is connected with rotating vane.Setting can guarantee that rabbling mechanism can steady operation like this.
In a preferred embodiment, described subcooled water spraying pack unit is atomizer, and it is evenly distributed in the bottom surface of described subcooled water box.Can effectively subcooled water evenly be sprayed on the sample in the test casing.
In a preferred embodiment, described sprinkling zone of heating is the heating silk thread that is distributed in inside, described subcooled water box bottom surface.The setting of heating silk thread seems convenient, and operation is also fairly simple.
The invention has the beneficial effects as follows:
(1) small-bore sprinkling subcooled water is more made sleet near the formation mechanism ground of sleet, and testing equipment can not cause because nozzle freezes the obstruction of flusher;
(2) used the climatic environment of manual simulation's accumulated ice sleet, can be used for product development and carry out the test of accumulated ice sleet, the situation of analog equipment when running into the weather of accumulated ice sleet, fault or the problem that may occur were estimated effectively in the development stage, thereby can improve pointedly, effectively reduce the probability that product breaks down when in use.
