The supercooled water, namely the liquid which is lower than the freezing point but is not solidified or crystallized, is called as supercooled liquid which is unstable because of lack of condensation nuclei in water, and the supercooled liquid can induce crystallization as long as a few crystals of the substance or suspended matters in water or the wall of a vessel, and the temperature of the supercooled liquid is raised back to the freezing point, so that the unstable state which can be quickly transformed under small disturbance is called as metastable state; when a saturated solution is slowly cooled in a suitable manner, it can be made supersaturated without precipitating crystals of the solute, a phenomenon also known as supercooling, and such a solution is called a supercooled solution, which is also unstable.
When the water in the heat-insulating box body 5 is cooled to about minus 2 ℃ by the evaporator 4, the water in the heat-insulating box body 5 is in a supercooled water state, namely an unstable metastable state, and the metastable state of the supercooled water is broken through the high-frequency vibration generated by the high-frequency vibration device 7, so that the ice crystal is separated out.
Example 2:
the difference from example 1 is that: the high-frequency vibration device 7 comprises a high-frequency coil device 71 arranged at the bottom of the heat preservation box body 5 and a permanent magnet spring piece 72 arranged at the upper part of the high-frequency coil device 71 and positioned in the heat preservation refrigerator, the high-frequency coil device 71 generates high-frequency magnetic force transformation under the control of the electric cabinet 3, so that the high-frequency coil device 71 can control the permanent magnet spring piece 72 to generate high-frequency vibration, and the high-frequency vibration generated by the permanent magnet spring piece 72 disturbs the metastable state of the supercooled water in the heat preservation box body 5, so that the supercooled water can separate out ice crystals.
The high-frequency coil device 71 may be disposed inside and outside the heat-insulating box 5, but generally, since the high-frequency coil device 71 generates heat when generating high-frequency vibration, which affects the state of supercooled water in the heat-insulating box 5 to increase the temperature in the heat-insulating box 5, the high-frequency coil device 71 is disposed at the bottom outside the heat-insulating box 5, and the permanent magnet spring pieces 72 are disposed at the upper portion of the high-frequency coil device 71 and are located in the heat-insulating refrigerator.
Example 3:
the difference from example 1 is that: the surface of the evaporator 4 in the heat preservation box body 5 is coated with an anti-icing nano coating, so that the surface of the evaporator 4 cannot be frozen, the effect and efficiency of heat exchange cannot be influenced by an icing layer when heat exchange is carried out, and the evaporator 4 coated with the anti-icing nano coating can carry out efficient heat exchange.

Example 5:
the difference from example 4 is that: the cylinder that insulation box 5 extends for being about being, because ice crystal density is less than water, and the ice crystal of making can come up to the surface of water evaporator 4 is located during insulation box 5's the bottom, be about the microscler cylinder that extends about being insulation box 5 compares the wide shape cylinder that extends of direction all around and can enlarge submarine distance to the surface of water, makes ice crystal and hydroenergy layering from top to bottom for the cylinder that extends about can not influence the efficiency of making snow when increasing the snow volume.
Example 1:
the difference from example 1 is that: the heat preservation box body 5 is also provided with a temperature display module for measuring the temperature in the heat preservation box body 5, the temperature display module is used for displaying the water temperature state in the heat preservation box body 5, and when the heat preservation box body is in a super-cooled water state, the high-frequency vibration device 7 can be started to make ice and snow; generally, the temperature display module may be disposed near a position near the evaporator 4; or a plurality of temperature display modules are arranged and respectively arranged at the upper part of the heat preservation box body 5 and the lower part of the heat preservation box body 5.
