Description
Technical Field
The utility model relates to a lithium cell technical field, concretely relates to lithium cell heat radiation structure.
Background
Can produce a large amount of heats when the lithium cell uses, if not give off in time, then can influence the performance of lithium cell, shorten the life of lithium cell, so generally set up heat radiation structure on soft packet of lithium cell or square lithium cell. Soft packet of lithium cell or square lithium cell include the electric core of a plurality of closed assemblies, are equipped with the heating panel between the electric core of a plurality of closed assemblies, and these heating panel peripheries are generally with electric core periphery parallel and level or contract in electric core periphery. Although the existing lithium battery heat dissipation structure has a certain heat dissipation effect, the heat dissipation effect is not ideal because the heat dissipation plate is covered by the battery core, and the heat generated by the lithium battery cannot be dissipated out in time.
Disclosure of Invention
The utility model discloses to prior art's not enough, provide one kind and can show improvement radiating effect, a heat radiation structure for soft packet of lithium cell or square lithium cell that in time distributes away the heat that the lithium cell produced.
The utility model discloses a technical goal is realized to following technical scheme.
A heat dissipation structure for a soft package lithium battery or a square lithium battery is arranged on the soft package lithium battery or the square lithium battery; the soft package lithium battery or the square lithium battery comprises a plurality of stacked battery cells; electrodes are arranged on the peripheries of the stacked electric cores; a heat dissipation plate is arranged between the stacked electric cores; the improvement is that: the heat dissipation plate extends out of more than 1 periphery except the periphery of the battery cell provided with the electrode.
In the above structure, the heat dissipation plate is disposed between the single electric cells.
In the structure, the heat dissipation plate is arranged among more than 2 electric cores.
In the structure, the periphery of the battery cell extending out of the heat dissipation plate is provided with an air channel.
Compared with the prior art, the utility model, following positive effect has:
1. the heat dissipation plate extends out of more than 1 periphery except the periphery of the battery cell provided with the electrode, and the heat dissipation plate is not completely covered by the battery cell, so that the heat dissipation effect is obviously improved.
2. The periphery of the battery cell extending out of the heat dissipation plate is provided with an air duct, so that the heat dissipation effect is further improved, and heat generated by the lithium battery is timely dissipated.
