PURPOSE:To enable cooling fit of core side part contracted and hole side part by cooling core side pat such as bush as well as dry ice in atmosphere in an adiabatic box with a sealing cover. CONSTITUTION:An adiabatic box 1 is made of plates in which an adiabatic material 1c is sealed between two steel plates 1a, 1b, and cylindrical separate boards 2 are removably accommodated. In the adiabatic box 1, a board wood 4 is placed on the bottom and core side parts 5 such as bushes are placed thereon. And dry ice 3 is filled to approx. 7/10 in openings among the core side parts 5, inner face of the box 1 and outer face of the cylindrical separate wall 2. And a wire net 6 is placed on the core side pats 5 and dry ice 3 is filled thereon. And a cover 8 is closed to seal the core side pats 5 with dry ice in atmosphere in the adiabatic box 1. Then, the core side parts 5 are taken out from the adiabatic box 1 and fit to hole side parts to complete cooling fitting. |
