The sleeve type multistage pulsating heat pipe comprises a heat source area, a high-temperature pulsating heat pipe, a low-temperature pulsating heat pipe and a heat sink area, and is structurally characterized in that the heat source area is connected with an evaporation section of the high-temperature pulsating heat pipe, a condensation section of the high-temperature pulsating heat pipe is connected with an evaporation section of the low-temperature pulsating heat pipe, and a condensation section of the low-temperature pulsating heat pipe is connected with the heat sink area; the device is characterized in that the evaporation sections and the condensation sections between different stages of pulsating heat pipes are connected through sleeve structures. The pulsating heat pipe can be applied to occasions with large cold and heat source temperature difference, it is ensured that each stage of pulsating heat pipe works in a high-performance temperature zone range, different stages of pulsating heat pipes are
