1. one kind is adapted to be mounted to the cold sotrage door that refrigerates on the cabinet, and described cold sotrage door comprises:

  • Inner layer glass with first surface and second surface, the described first surface of described inner layer glass is configured to the inside of described refrigeration cabinet adjacent;

    Glass outer with first surface and second surface, the described first surface of described glass outer are configured to outside adjacent with described refrigeration cabinet;

    Intermediate glass between described inner layer glass and described glass outer;

    First seal, it is around the periphery setting of described inner layer glass and described intermediate glass, so that the relation that described inner layer glass and the maintenance of described intermediate glass are spaced apart from each other;

    Second seal, it is around the periphery setting of described glass outer and described middle glass, so that the relation that described glass outer and the maintenance of described intermediate glass are spaced apart from each other;

    The first low heat radiation cover layer with the described second surface adjacency of described inner layer glass;

    The second low heat radiation cover layer with the described second surface adjacency of described glass outer;

    Described inner layer glass, glass outer, intermediate glass, first seal, second seal and described first and second low heat radiation cover layer have constituted a heat-protecting glass device, the U value of described heat-protecting glass device is equal to or less than 0.2Btu/hr-sqft-F substantially, carries out electrical heating and can prevent to produce condensation thereon thereby need not described first surface to described glass outer;

    AndAround the fixing framework of the periphery of described heat-protecting glass device.
