Patent ID: 8127559

Claim:
A core unit for a refrigeration unit, comprising: a substantially-rectangular first plate member and a substantially-rectangular second plate member spaced apart and arranged in parallel with each other; an electric wave transmission antenna arranged between first edges of the first plate member and the second plate member so as to enable the transmission of an electric wave toward sides of the first plate member and the second plate member; and first magnetic bodies arranged in the first plate member at the side of the second plate member, and second magnetic bodies arranged in the second plate member at the side of the first plate member; and a current plate arranged between opposing second edges of the first plate member and the second plate member so as to enable rectification of air flowing toward sides of the first plate member and the second plate member, wherein unidirectional and substantially-uniform static magnetic field is formed in substantially normal directions of a principal surface of the first plate member and a principal surface of the second plate member between the first plate member and the second plate member, and the first plate member, the second plate member and the current plate are arranged so as to have the principal surface of the first plate member and the principal surface of the second plate member be roughly perpendicular to the principal surface of the current plate, and the current plate and the electric wave transmission antenna are adjacent to each other.
