Description
Technical field
The utility model relates to portable power source technical field, is specifically related to a kind of battery pack of high heat conduction.
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 high temperature bad border, 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 of high heat conduction.
For solving above technical problem, the technical solution of the utility model is:
A battery pack for high heat conduction, comprises the first metal shell, the battery cell of series/parallel connection and the silica gel heat carrier that is arranged in the first metal shell.Silica gel heat carrier comprises base plate, two side plates be arranged on base plate, the interlayer that is arranged on the top cover on side plate and is arranged between base plate and top cover, the side of interlayer is connected with side plate, be provided with battery compartment between adjacent spacers, battery cell is arranged in battery compartment.Base plate, side plate, top cover and interlayer all adopt silica gel Heat Conduction Material to make.
Concrete, be provided with epoxy resins insulation plate in interlayer.
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 silica gel heat carrier, on the one hand, heat conduction to the first metal shell that silica gel heat carrier 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 heat carrier by heat conduction to cell, improve the charging effect of battery pack under low temperature environment.Silica gel heat carrier has flexible software, and when cell expands, silica gel heat conduction physical efficiency avoids neighboring unit cell contact friction, strengthens the safety in utilization of battery pack.The interlayer material be made up of silica gel Heat Conduction Material in silica gel heat carrier is softer, and the epoxy resins insulation plate installing hard in interlayer additional can improve the mechanical strength of interlayer.Silica gel heat carrier 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.
