A kind of cold and hot coating apparatus includes a contact mould group, a cold and hot modulus of conversion group, a limit mould group and a springform group. The contact mould group includes the surrounding wall that a bottom wall, one upwardly extend from the bottom wall periphery and one from the outwardly extending wall extension in the other side of the opposite what bottom wall of the surrounding wall. The cold and hot modulus of conversion group includes a cooling wafer connecting with the bottom wall inner wall. The limit mould group surrounds the contact mould group in frame shape, including one first limited wall and one second limited wall separately parallel to each other. The wall extension is against first limited wall, and the springform group is arranged between the what wall extension and second limited wall, to apply the permanent bias against what first limited wall to the wall extension. Cooling and heating function of the bottom wall using the cooling wafer, affected part telescopically ice compress or the hot compress to user.一種冷熱敷裝置，包含一接觸模組、一冷熱轉換模組、一限位模組及一彈性模組。該接觸模組包括一底壁、一自該底壁周緣向上延伸的圍繞壁，及一自該圍繞壁相反於該底壁之另一側向外延伸的延伸壁。該冷熱轉換模組包括一與該底壁內壁面連接的致冷晶片。該限位模組呈框形圍繞該接觸模組，包括彼此平行相間隔的一第一限位壁及一第二限位壁。該延伸壁抵靠該第一限位壁，且該彈性模組設置於該延伸壁及該第二限位壁間，以對該延伸壁施加恆抵靠於該第一限位壁的偏壓。該底壁利用該致冷晶片之冷卻與加熱功能，對使用者之患部伸縮地冰敷或熱敷。
