The invention discloses a cylindrical battery thermal management module based on a pulsating heat pipe. Single batteries are arranged in an array to form a battery array, gaps are formed between adjacent single batteries and are filled with heat conductors, the heat conductors are attached to the surfaces of the single batteries, and the pulsating heat pipe penetrates through the heat conductors up and down in a vertical pipe form. All the vertical pipes in the battery array are orderly connected and are connected with the heat exchange pipes to form a closed pulsating heat pipe circulation loop based on the pulsating heat pipes, so that heat transfer among the pulsating heat pipes, the heat conductors and the single batteries is realized; the heat exchange pipes are arranged in the heat exchange cavity, the heat exchange cavity is provided with an upper cavity and a lower cavity which are mutually independent, the upper cavity can be communicated with an external cold source, and thelower cavity can be communicated with an external heat source. By combining the heat conductors with the pulsating heat pipe, rapid heating or rapid heat dissipation of the power battery pack is realized, the heat transfer rate and temperature uniformity of thermal management of the power battery pack are effectively improved, and shock absorption and inhibition of thermal runaway expansion of thepower battery can be realized.
