SUPERCOOLING APPARATUS

摘要

A supercooling device is provided to keep an object in supercooled state for a long time by forming an electric field for a certain area. A supercooling device comprises a storing chamber, a cooling cycle, an electrode unit. The storing chamber stores an object in a receiving space. The cooling cycle cools down the receiving space. The electrode unit is symmetrically arranged to the receiving space. The electrode unit is composed of a first electrode(11a) and a second electrode(11b) which have different sizes to keep the object in supercooled state below phase transformation temperature. The electrode unit is mounted at an inner surface of the storing chamber. The first electrode is an active electrode which is also called a planar electrode. The second electrode is a grounding electrode. The first electrode has a larger area than the second electrode.
