Abstract: A copper bar protection structure (10) includes an upper housing (11) and a lower housing (12) that are engaged with each other. A receiving groove (14) is provided on each of engagement surfaces (15) of the upper housing (11) and the lower housing (12). The two receiving grooves (14) are combined into a copper bar accommodating space. A phase change material layer (30) is laid on an inner wall (13) of the receiving groove (14). The copper bar (20) is wrapped by the phase change material layer (30) when the copper bar accommodating space accommodates a copper bar (20).
