9. A heat dissipating device, comprising:
a second heat dissipation member detachably connectable to the first heat dissipation member of the electric storage device;
the heat conversion part is arranged on the first side surface of the second heat dissipation part;
in a state where the first heat dissipation member and the second heat dissipation member are detachably attached, a first portion of the first heat dissipation member is in contact with the heat conversion member, and heat between the second heat dissipation member and the first heat dissipation member can be transferred through the heat conversion member; wherein the first portion of the first heat dissipation element is located outside a housing of the electric storage device.
10. The heat dissipating device of claim 9, further comprising:
the second radiator is provided with at least two second radiating fins arranged at intervals and arranged on the second side surface of the second radiating piece; wherein the second side of the second heat sink and the first side of the second heat sink are opposite sides of the second heat sink;
and the fan is arranged on the second side surface of the second heat dissipation piece and used for blowing air to the second heat dissipation piece.
