Anti-icing and anti-cracking metal thermal insulation ice box and anti-icing and anti-cracking method of container

The invention provides an anti-icing and anti-cracking metal thermal insulation ice box and an anti-icing and anti-cracking method of a container. The metal thermal insulation ice box comprises a metal shell, wherein an inner cavity of the metal shell is filled with cooling liquid, the upper surface of the metal shell is a heat transfer surface, and the inner cavity of the metal shell is providedwith an expansion body which does not absorb water and is compressible. When the cooling liquid is in a liquid state, the expansion body is in a natural expansion state and occupies a certain volume of the inner cavity. When the metal thermal insulation ice box is put into a cold source to be frozen, the volume of the cooling liquid becomes larger after freezing to compress the expansion body to obtain space, the cracking of the metal shell is effectively prevented, and the quality reliability of the metal thermal insulation ice box is improved. 本发明提供种抗结冰胀裂的金属保温冰盒及防容器结冰胀裂的方法，金属保温冰盒包括金属壳体，所述金属壳体内腔填充有冷却液，所述金属壳体上表面为传热面，所
