Content of the utility model
[6]
Purpose of the utility model is: against the above problem, provides a battery pack and battery with the power battery, in order to promote the heat conduction performance of the battery pack.
[7]
In order to achieve the above purpose, the utility model the technical scheme is:
[8]
A battery pack, including in series and parallel combination are connected together by a plurality of batteries monomer and formed between the monomers of these battery a number of cell gap, characterized in that in at least one of said battery is inserted in the gap between the 1st heat conducting layer, the at least one of the battery pack arranged on the outer surface of the 1st and the 2nd heat conducting layer is connected with the heat conducting layer, the heat conducting layer includes aluminum plate 1st layer I and I are combined on the aluminum surface of the positive and negative sides of the two layers of silica gel I, the 2nd heat conducting layer II comprises an aluminum plate layer II and composite in the aluminum on the inner side of the silica gel layer II II, the silica gel layer in the vicinity of I with the battery contact arrangement, the silica gel layer II with the outer surface of the battery pack in the battery cell contact arrangement.
[9]
In the utility model on the basis of the above technical scheme, also comprises the following preferred scheme:
[10]
The 1st and 2nd heat conducting sheet into an integral structure.
[11]
The 2nd heat conducting layer by the 1st heat conducting layer after bending the bent portion of the rip is on the outer side face I to form silica gel.
[12]
The 2nd heat conducting layer further includes a compound in the aluminum silica gel layer on the outer side face II II, by the 1st 2nd heat conducting the bend and form the heat conducting layer.
[13]
The 1st and 2nd heat conducting conducting a split structure, the two butt joint structure are connected with each other through the heat conducting layer.
[14]
The states the heat conduction piece butt joint structure includes forming said 2nd heat conducting the lug and the end of the opening for the 2nd on conducting strip to the joint, the connecting lug passes through to the seam in the bending processing and the 2nd against the outer surface of the heat conducting layer.
[15]
The 2nd heat conducting layer further includes a compound in the aluminum on the outer side face II II of the silica gel.
[16]
Each said battery of monomer with the 1st or the 2nd heat conducting sheet heat conducting contact.
[17]
In each of the battery pack are respectively arranged on the outer surface of the said 2nd heat conducting layer.
[18]
The battery pack as in claim 1 - 7 in any of the battery pack, the 2nd heat conducting with the outer side surface of the inner wall of the battery case of the contact arrangement.
[19]
The advantages of the utility model is:
[20]
1. the utility model aluminum and silica gel this two material through the composite process are made into a whole, and its skillfully arranged to in the battery pack, thus realizing the battery pack in the working process as soon as possible of the heat energy generated is conducted to the external, enable the battery pack to rapidly reduce the temperature, to ensure that the heat conducting layer of insulation between the battery at the same time, not only solves the charging of the battery pack is placed, in the electrical process dissipation problem, also improved battery PACK process, improving the overall safety of the battery pack, reliability.
[21]
2. the battery pack located in the interior of the conducting strip and located at the surface of the 1st 2nd heat conducting layer of the battery pack is made up of a connected structure, easily and quickly assembled.
