Snowfall simulation device and equipment

Abstract

The invention discloses a snowfall simulation device and equipment. The snowfall simulation device comprises a nozzle and heat exchangers, wherein the nozzle is used for introducing liquid and atomizing and spraying the liquid; the heat exchangers are arranged above the spraying direction of the nozzle, and the heat exchangers are closed annular tubes and provided with inlets used for introducingrefrigerants; inner rings of the heat exchangers are provided with a plurality of refrigerant spraying pipes at intervals in the circumferential direction; included angles are formed between the axesof the refrigerant spraying pipes and the inner rings of the heat exchangers; and the included angles are configured in the mode that the refrigerants sprayed by the refrigerant spraying pipes form cooling swirling flow in the centers of the heat exchangers. According to the device, the low-temperature environment can be created above the spraying direction of the nozzle, the structure is simple,a cold load under the snowfall condition in the laboratory environment can be reduced, requirements on the overall environment of a laboratory are remarkably reduced, and the cost is reduced. By meansof the low-temperature cooling swirling flow formed by the refrigerants sprayed by the refrigerant spraying pipes in the inner rings of the heat exchangers, atomized droplets can make full contact and exchange heat, and snowfall is fully developed in a small area.

Description

technical field [0001] The invention relates to the technical field of artificial simulation of meteorological environment, in particular to a snowfall simulation device and equipment. Background technique [0002] The artificial snow simulation device is a snow simulator used in the environmental simulation laboratory. [0003] The principle of a commonly used artificial snowmaking method is: first, the water is made into flake ice through the ice making device, and then the flake ice that has been made is crushed into powder through the ice crushing device, and finally, the powdered ice crystals are conveyed through the air sent by the system. The snowmaking system of this method is complicated, and the quality of the snow produced is far from that of natural snow. [0004] The principle of another commonly used snow simulator is: place a water mist nozzle (snow gun) on the top of the environmental laboratory, and then create a low-temperature environment in the environm...
