The invention provides an intelligent temperature protection device comprising multiple thermal insulation devices, connecting devices, connecting holes, a control board, a display screen and connecting wires. The thermal insulation devices are connected together via the connecting devices; one side of each thermal insulation layer is provided with one connecting hole and the control board is connected with the thermal insulation devices via the connecting wires; the display screen is arranged on the control board; the connecting holes in the side surfaces of the thermal insulation devices match the connecting wires. The intelligent temperature protection device is reasonable in design and simple in structure; the thermal insulation devices can be spliced via the connecting devices, so that the exposed part around a surgery site of a patient is reduced maximally and the thermal insulation effect is greatly increased.
