Battery module having modified heat pipe structure

A battery module, including:

• a plurality of battery cells;
• a battery fixed holder used for accommodating and fixing the plurality of battery cells;
• and
• a modified heat pipe structure including a metal tube, the metal tube including:
• a thermal conduction section being a vacuum-pumped sealed tube that includes a wick structure and a working fluid thereinside, and transfers heat through a process of evaporation and condensation of the working fluid, wherein the thermal conduction section is placed above the battery fixed holder;
• a first container section, placed in a gap between the plurality of adjacent battery cells, and used to store the heat generated by the plurality of adjacent battery cells in charging or discharging;
• and
• a first connection section, provided with one end connected to the first container section, and provided with other end connected to one end of the thermal conduction section by passing through the battery fixed holder vertically, wherein the first connection section conducts the heat absorbed by the first container section to the thermal conduction section.
