Abstract: Disclosed herein is a heat dissipating device for a battery pack which comprises a heat pipe and a heat collecting plate comprising a bottom heat collecting plate and an upper heat collecting plate each having a hole therein, wherein two ends of the heat pipe are inserted respectively into the holes in the bottom heat collecting plate and the upper heat collecting plate. A battery using the heat dissipating device is also disclosed. During the operation of the heat dissipating device, since the heat generated by the cells can be colleted in the upper heat collecting plate, then transmitted to the bottom heat collecting plate through the heat pipe, and finally dissipated outwardly by the bottom heat collecting plate, the heat generated by cells can be dissipated rapidly and efficiently.
