Problems solved by technology

[0005] The existing induction ring forms corresponding vibrations under the action of the static magnetic field, but the lower induction ring generates an induction current, so the surface temperature will also increase accordingly, and the radial expansion of the induction ring increases. With the increase of expansion, the original moving gas The air gap will be reduced accordingly. In the process of fan cooling and exhaust cooling, the original cooling air flow through the surface of the induction ring will be reduced and the wind pressure will be increased, which will affect the cooling efficiency. In order to take away the heat of the induction ring as soon as possible, high efficiency is still required. The evaporative cooling logic control method, through the spray (liquid nitrogen) cooling device, sprays a small amount of atomized distilled water vapor on its surface, so that the heat generated on the surface is quickly vaporized and evaporated, and then the latent heat is taken away by the air flow, thereby controlling the heating of the induction ring The final radial expansion size can improve the heat dissipation effect and improve the trouble-free working time of vibration equipment. Therefore, a new type of evaporative cooling control logic method is needed to solve the existing problems.
