Description
Technical field
The utility model relates to portable power source technical field, is specifically related to a kind of battery pack with silica gel conducting strip.
Background technology
Existing battery pack uses multiple cell to be encapsulated in metal shell through series/parallel, and there is the disadvantageous problem of heat radiation in discharge process under hot environment, there is the poor problem of charging effect in charging process under low temperature bad border, ambient adaptability is poor.In addition, battery pack there will be the situation that cell expands after long-time use, and the contact friction because of expansion of adjacent cell, very easily has an accident.The each discharge and recharge of battery pack also there will be swollen account and contraction (swollen account of charging, contraction of discharge), and rate of change is generally about 3%.
Utility model content
The smooth and cell of the heat conduction existed for existing battery pack expands the deficiency causing safety in utilization to reduce, and the utility model provides a kind of battery pack with silica gel conducting strip.
For solving above technical problem, the technical solution of the utility model is:
There is a battery pack for silica gel conducting strip, comprise the first metal shell, the battery cell of series/parallel connection and the silica gel conducting strip that is arranged on battery cell.The area of plane of silica gel conducting strip is greater than the area of plane of battery cell, and the complete clad battery monomer of silica gel conducting strip.Silica gel conducting strip is connected with the first metal shell by flank.
Concrete, the length of flank is more than or equal to 5cm.
Concrete, battery pack comprises the second metal shell be arranged on outside the first metal shell and the hot air apparatus be arranged in the second metal shell.
The beneficial effects of the utility model: battery pack of the present utility model comprises the silica gel conducting strip covered on each cell, on the one hand, heat conduction to the first metal shell that silica gel conducting strip will discharge in cell discharge process, and be finally released into the external world, avoid cell to heat up too high, ensure that the continuous discharge of cell runs; On the other hand, when ambient temperature is lower, starts hot air apparatus to heat the first metal shell, utilize silica gel conducting strip by heat conduction to cell, improve the charging effect of battery pack under low temperature environment.Silica gel conducting strip has flexible software, and when cell expands, silica gel conducting strip can avoid neighboring unit cell contact friction, strengthens the safety in utilization of battery pack.Silica gel conducting strip has excellent heat conductivility and insulation property, for safe and reliable in battery pack.The conductive coefficient of silica gel conducting strip, up to 1600W/mK, is equivalent to the 2-4 of copper doubly, and doubly, its thermal resistance is lower than aluminium by 40%, lower than copper by 20% for the 3-6 of aluminium.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1 first metal shell, 2 battery cells, 3 silica gel conducting strips, 3-1 flank, 4 second metal shells, 5 hot air apparatus.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to Fig. 1, embodiment comprises the first metal shell 1, the second metal shell 4 be arranged on outside the first metal shell 1, the hot air apparatus 5 be arranged in the second metal shell 4, be arranged on the battery cell 2 in the first metal shell 1 and cover the silica gel conducting strip 3 of battery cell 2 upper surface.The area of plane of silica gel conducting strip 3 is greater than the area of plane of battery cell 2, and the complete clad battery monomer 2 of silica gel conducting strip 3.In silica gel conducting strip 3, the part of non-clad battery monomer 2 constitutes flank 3-1, and flank 3-1 is connected with the first metal shell 1, the length of flank 3-1
lfor 5cm.
In the present embodiment, hot air apparatus 5 comprises heat-generating pipe and fan, heat-generating pipe and the equal external power supply of fan.
The above execution mode is only preferred embodiment of the present utility model, and is not the exhaustive of the feasible enforcement of the utility model.For persons skilled in the art, to any apparent change done by it under the prerequisite not deviating from the utility model principle and spirit, all should be contemplated as falling with within claims of the present utility model.
