なければならない。2. Description of the Related Art When selecting a plate so as to withstand the external pressure applied to the surface of the plate, which is very large unlike a cylinder,
Regardless of whether the thickness of the plate is selected by calculation or based on past results, it is inevitable that the thickness of the plate increases in order to design it to withstand external pressure. As far as possible, a flat plate structure was avoided, and a circular shape had to be selected at the expense of space and the like. The square (flat) structure only sacrifice weight and other items when the product is not square.
Has been produced. The heat insulation panel has a heat insulation structure in which blocks of square sides are laminated with a heat insulating material such as foamed polyurethane or foamed styrene to block outside air and keep the inside warm. It is used in transport freezers, homes, refrigerators, industrial freezers, and home insulation. Generally, both the inner and outer tanks are covered with metal such as aluminum to increase the strength. This prevents rain from seeping into the insulation when it is exposed to the atmosphere, resulting in poor insulation. Actual refrigerators, refrigerators, industrial freezers, etc. use insulation materials such as foamed polyurethane and foamed styrene, but because of the large inflow of external heat, load large refrigerators to prevent the temperature from rising at any time. The refrigerator must be operated.
