Claims (1)

[Scope of utility model registration request] In a cooling floor in which columns are erected on a concrete foundation and the columns support a pedestal for placing objects to be cooled, a gap is provided between the pedestal and the concrete foundation to allow cooling air to pass through. A heat shielding section consisting of multiple layers of upper and lower heat shielding members made of a heat-resistant material is provided, and the gaps between adjacent upper and lower heat shielding members are not penetrated by an imaginary perpendicular line. A cooling bed characterized in that it is placed in a certain area.
