Abstract: The present disclosure relates to a pulsating heat pipe-based battery cooling module and a battery unit including the same. The cooling module using the pulsating heat pipe may include: a plurality of heating plates which are arranged in parallel such that both sides or one side of the heating plates contact a plurality of battery cells, while forming a space in which the plurality of battery cells are accommodatable; at least one cooling plate which allows a coolant to flow; and a plurality of channels which are in contact with the plurality of heating plates and the at least one cooling plate, have a sealed tube shape and a working fluid filled in a portion of the sealed tube shape in such a way as to function as the pulsating heat pipe. The proposed cooling module minimizes the temperature difference within the battery cell and efficiently absorbs the heat, thereby reducing the overall temperature of the battery cell.

Abstract: Provided are a flat plate pulsating heat pipe having flexibility and having an improved sealing ability so as not to leak a working fluid therein, and a manufacturing method thereof. The flat plate pulsating heat pipe includes a base part having an upper surface or a lower surface which is plasma-treated, wherein the base part has a plurality of channels formed therein and both end portions of each of the channels are bent and connected to each other to form a closed-loop type or a closed type; and a pair of surface films bonded to an upper portion and a lower portion of the base part and bonded to each other at an outer portion of the base part to seal the channels.
