Description
Technical field
It the utility model is related to lithium battery box technical field, and in particular to a kind of lightweight lithium battery of phase-change heat material
Case.
Background technology
Lithium battery box is the important protection of new energy dynamical system lithium battery, is the overall important component of lithium battery group, is
New-energy automobile provides motive power.Due to being limited by material, current lithium battery casing is mainly prepared by metal material, is led
Box weight is caused to remain high, while in torrid areas, because the high heat distributed plus battery operation of environment temperature, leads
Battery temperature is higher in cause casing, and battery temperature is raised and can not timely and effectively dissipated, and brings potential safety hazard.
Utility model content
The technical problems to be solved in the utility model is, a kind of customer service the deficiencies in the prior art, there is provided phase-change heat material
The lightweight lithium battery box of material, solve lithium battery box casing lightweight problem, while strengthen the heat dispersion of Battery case.
Specific solution is as follows：
A kind of lightweight lithium battery box of phase-change heat material, including casing, the box body wall include the carbon fiber of outer layer
The phase-change heat layer of housing and internal layer, connected by casing play between carbon fiber shell and the phase-change heat layer, the skeleton
Layer is the triangulation network grating texture being interwoven by carbon fiber rod；The phase-change heat layer is paraffin composite, the paraffin
The fusing point of composite is 40 DEG C -50 DEG C.
The beneficial effects of the utility model are：A kind of lightweight lithium battery box of phase-change heat material of the present utility model,
Low manufacture cost, reliable in quality, lighter in weight, casing use carbon fibre material, by composite forming technology, by the carbon of box body wall
Filament case is arranged on the casing play in casing, and casing play is the triangular mesh knot being interwoven using high-strength carbon fiber rod
Structure so that casing intensity reaches the several times of equal metal cabinet；On cabinet wall, in inlaying fusing point on casing play in 40-50
Degree Celsius paraffin composite as phase-change heat layer material, when internal temperature reaches phase-change material fusing point, phase-change material
It will absorb heat, melt, while heat will be scattered and disappeared away rapidly by the carbon fiber shell outer wall of casing, and substantially increase casing radiating
Performance.
Brief description of the drawings
Fig. 1 is layer structure schematic diagram of the present utility model；
Fig. 2 is support framework structure schematic diagram of the present utility model；
Fig. 3 is overall structure diagram of the present utility model.
Embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
The lightweight lithium battery box of reference picture 1 and a kind of phase-change heat material shown in Fig. 3, including casing 1, the casing
1 wall includes the carbon fiber shell 11 of outer layer and the phase-change heat layer 13 of internal layer, the carbon fiber shell 11 and phase-change heat layer 13
Between connected by casing play 12.
Carbon fibre material possesses high intensity, flame-resistant insulation performance；Intensity can bear external impact etc., be provided simultaneously with corrosion resistant
Corrosion energy.Carbon fibre composite density is 1.7g/cm3Left and right, lower than density metal is more, therefore casing can solve
While intensity, box weight is substantially reduced, realizes lightweight, high intensity battery case.
Shown in reference picture 2, the casing play 12 is the triangulation network grating texture being interwoven by carbon fiber rod；Casing play leads to
Transverse direction and longitudinal direction structure design is crossed, forms stable triangle stress relation so that body structure can disperse casing stress significantly.
The phase-change heat layer 13 is paraffin composite, and the fusing point of the paraffin composite is 40 DEG C -50 DEG C.Paraffin
Composite is as phase-change heat layer material, and when internal temperature reaches phase-change material fusing point, phase-change material will absorb heat, and melt,
Heat is scattered and disappeared away rapidly by the carbon fiber shell outer wall of casing simultaneously.
For casing intensity of the present utility model than traditional high several times of metal battery casing intensity, quality is only metal battery case
Half of body or so；It can only be radiated because box interior temperature exchanges with external temperature by box body wall, the utility model passes through
Increase paraffin composite material on cabinet wall to melt absorption cell heat and radiate with box body wall contact, substantially increase
Box interior temperature radiating efficiency, available for a variety of new energy vehicles, it can in a variety of contexts use, improve lithium battery box
The practicality of body.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New scope is defined, and on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to this
The various modifications and improvement that the technical scheme of utility model is made, the protection of the utility model claims book determination all should be fallen into
In the range of.
