The bearing of trend of post battery is consistent, and described connection support is installed on two ends of cylindrical battery, it include anode ear and
Negative electrode lug is contained in resettlement section therein, is formed with depressed part and jut, described depression on the outer surface connecting support
Portion and jut are arranged separately, and described heat pipe includes connecting portion and terminal part, and terminal part is installed in through hole, connect
Portion is installed on a side surface of aluminium base, and on the opposite side surface of aluminium base, laminating assembles fin.
Further, the depressed part on support is connected with another even by one of them between two adjacent connection supports
Connect the jut on support to be buckled to fix mutually in together.
Further, described cooling stand is made up of commercial-purity aluminium.
Further, described heat pipe be shaped as U-shaped, linear, S-shaped or M shape.
This utility model have the advantages that cylindrical battery in charge and discharge process, internal chemical reaction complexity, and
Being attended by the generation of heat, the cylindrical battery group formed especially for multiple cylindrical batteries, the gathering of temperature faster, makes
Cylindrical battery group is internal produces rapidly substantial amounts of heat build-up, it is necessary to cause cylindrical battery group temperature to raise and Temperature Distribution
Unbalanced, this utility model cylindrical battery group fits tightly cylindrical battery surface by heat absorption by cooling stand, connects
And conducted heat on aluminium base by heat pipe, then carry out heat absorption diffusion by the fin on aluminium base.Simultaneously
Assembled by carrying out connection in series-parallel between cylindrical battery by connecting support.
