Abstract:
An energy storage system includes multiple cells, a heat pipe, a first heat transfer channel, and a second heat transfer channel. Each cell has a first end with anode and cathode terminals and a second end opposite the first end with the multiple cells arranged so that the second ends are aligned. The heat pipe has a U-shape and includes an evaporation portion having a flat evaporation surface facing the second ends of the multiple cells, a first condensation portion oriented substantially perpendicular to the evaporation portion, and a second condensation portion oriented substantially perpendicular to the evaporation portion. The first condensation portion is at a first end of the evaporation portion and the second condensation portion is at a second end of the evaporation portion. The first heat transfer channel abuts the first condensation portion and the second heat transfer channel abuts the second condensation portion.
