The present invention aims to provide a means for releasing heat generated during charging in a simple manner without affecting the design of the battery itself. , is characterized in that a flat heat pipe is arranged in contact with the side wall surface of the unit battery so that its heat dissipation part protrudes from the lid surface.

That is, FIG. 1 is a schematic plan view thereof, and FIG. 2 is a front sectional view thereof. And in these drawings, 1 is 450AH15HR (vertical 150*f with D capacity at 5 hour rate discharge)
2 is a storage box in which a total of 24 unit batteries 1 are stored in 4 rows of 6 units horizontally and 4 columns vertically. A total of four copper-water-based flat heat pipes 3 each having a thickness of 5 fins, a width of 20 mm, and a height of 500 mm are inserted between the four central unit batteries.

20 aluminum cooling fins 5 each having a width of 50 mm and a length of 100 mm are arranged.

なお該ヒートパイプ３は非常に薄いので、単位電池１の
電槽の可撓性と相まって隙間の問題は特には生じない。Note that since the heat pipe 3 is very thin, combined with the flexibility of the container of the unit battery 1, there is no particular problem with gaps.

When continuous overcharging was performed, the temperature stopped rising by 36°C above room temperature, and a 9°C drop in temperature was observed, compared to a 45°C rise above room temperature without a heat pipe. It was done. Furthermore, the cooling fin 4 part is 20W
When forced air cooling was applied from a distance of 50 cm using a small fan, the temperature rose only 31°C above room temperature, but only 14°C.
A decrease in temperature was observed.

も効果的であるが、これに限定されるものではない。Although one embodiment of the present invention has been described above, various embodiments of the present invention can be considered without departing from the spirit thereof. In other words, the most effective position for installing the heat pipe is to place it in contact with the side wall surface of the unit battery 1 near the center where the temperature is most likely to rise, as shown in the above embodiment. It is not limited to.

また本発明ではそのヒートパイプを直接電池の電解液中
