Working principle: this programme can solve mention in the prior art 1,2 problems.The formation of cyclone can be divided into four A stage:

(1) unstability of atmosphere generates strong ascending air, since the maximum in torrent is passed by the influence of air-flow, it It is further strengthened.

(2) due to there is the wind facies interaction of shear with speed in vertical direction and direction, ascending air is in troposphere Middle part start to rotate, formed mesoscale cyclone.

(3) as mesoscale cyclone develops to the ground and stretching, extension, itself attenuate and enhance upwards.A meanwhile facet Long-pending enhancing convergence, i.e. nascent spout are formed inside cyclone, generate the same process of cyclone, form spout core.

(4) difference in the rotation and cyclone in spout core, its intensity are enough that spout is made to be stretched over ground always.When When the vortex of development reaches ground level, surface pressure sharply declines, and ground wind speed steeply rises, and forms cyclone.

The forming process of cyclone is strong convection vortex occurring principle, and the program utilizes strong convection vortex occurring principle, The forming process being vortexed by simulation strong convection, accelerates air circulation by vortex that the device generates to reach raising cargo The purpose contacted with cold air, and the quick-frozen time of cargo is reduced, reduce energy consumption.Compared with traditional freezer, the device The equipment expenditure and energy consumption to promote air flowing in freezer are significantly reduced, is reached needed for being met using natural principle Effect.

Underlying gas is siphoned away when pipeline fan 9 works, then bottom plate 1 is formed about negative pressuren zone and forces week near bottom plate 1 Side air is flowed to negative pressuren zone, and the air of bottom is higher relative to its temperature by the air of plate-fin heat exchanger 11 therefore logical Cold air after crossing plate-fin heat exchanger 11 can since the gas collet 8 of top by tracheae 3 and venthole 4 from top to Flowing underneath, this just forms the process of an air circulation, when by cargo as in the device, with device unlatching its The air flowing of generation can promote the convective heat transfer of cargo and cold air to shorten the quick-frozen time to enhance quick-frozen effect, reduce Energy consumption.Air mobility status See Figure 5.

Therefore the quick-freezing plant of the fast freezing cargo, using strong convection vortex occurring principle for improving air circulation speed Degree, shortens the cooling time of cargo, and reduces energy consumption, and the device can effectively shorten identical goods compared with traditional freezer The quick-frozen time of object only needs 5-6 small quick-frozen effect needs 8 hours or more needed for reaching in traditional freezer using the device When, due to the shortening of quick-frozen time, its corresponding energy consumption can also be reduced.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
