Embodiment
Below execution mode of the present utility model is specifically described.
As shown in Figures 1 to 5, phase-change material energy storage rod described in the utility model is made up of the first housing 1, second housing 2, heat-conducting silica gel sheet 3 and phase-change material 4.The first described housing 1 and the second housing 2 are made up of heat conduction, insulation and fire-retardant material.
As shown in Figures 2 and 3, described first housing 1 is the housing closing openings at one side, and housing is formed primarily of four circular arc wall A, planar wall 12 and cylindrical wall B.Parallel to each other and the symmetrical handing-over of four described circular arc wall A.Described planar wall 12 and four circular arc wall A handing-over, the single-ended space closed four circular arc wall A and surround.Described cylindrical wall B is arranged at the centre that four circular arc wall A surround, and is provided with some ribs 14 therebetween and connects.Cylindrical wall B and planar wall 12 join, and hole C and planar wall 12 handing-over run through.Four described circular arc wall A are provided with groove 111 and are provided with recessed seam 112 at open at one end in illustrated position, described cylindrical wall B is provided with recessed seam 132 at open at one end.
Described second housing 2 is that housing is formed primarily of four circular arc wall A, planar wall 22 and cylindrical wall B while close the housing of openings at one side.Parallel to each other and the symmetrical handing-over of four described circular arc wall A.Described planar wall 22 and four circular arc wall A handing-over, the single-ended space closed four circular arc wall A and surround.Described cylindrical wall B is arranged at the centre that four circular arc wall A surround, and is provided with some ribs 24 therebetween and connects.Cylindrical wall B and planar wall 22 join, and hole C and planar wall 22 handing-over run through.Four described circular arc wall A are provided with groove 211 and arrange male half coupling 212 at open at one end in illustrated position, described cylindrical wall B is provided with male half coupling 232 at open at one end.
The first described housing 1 is identical with size symmetry with the second housing 2 structure, and difference is seam position.After two housing assemblings, the male half coupling 212,232 of recessed seam 112,132 and second housing 2 of the first housing 1 closely cooperates mutually.From said structure, the space of assembling the inside of latter two housing is formed closed, and as shown in Figure 4, phase-change material 4 can be filled, phase-change material and housing close contact in the space closed.
Again as shown in Figure 1 and Figure 4, in the fitted in groove 111,211 of heat-conducting silica gel sheet 3, the surface 31 of heat-conducting silica gel sheet 3 and housing closely cooperate.
As Fig. 5, in the battery pack structure of cylindrical battery composition, a phase-change material rod can be assembled in the space that every four cylindrical batteries 5 arrange rear interval, the surface 32 of the hot silica gel piece 3 on phase-change material rod and the face of cylinder close contact of battery.
The architectural feature of this phase-change material rod in sum, its beneficial effect is: phase-change material is encapsulated in shell, remains the good heat conduction of phase-change material and thermal storage performance, improves fire-retardant and insulation property.Phase-change material, by storing certain heat, realizes the samming effect to battery.When the heat of phase-change material rod storage is saturated, by increasing fluid cooling provision, the fluid making temperature relatively low, through the interstitial hole C of phase-change material rod, is lowered the temperature to phase-change material rod, reaches the effect of secondary heat radiation.Greatest improvement of the present utility model is, the heat management of temperature when single battery is worked is achieved under the condition not increasing battery case volume, do not reduce the volume energy density of battery case, improve the performance of battery, extend the useful life of battery, add overall security and the environmental suitability of battery case, there is stronger practical value.
Above-described embodiment is the utility model preferably execution mode; but execution mode of the present utility model is not restricted to the described embodiments; as changed the position of wherein parts, quantity or changing the shape etc. of housing; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be substitute mode and the technical scheme of equivalence, be included within protection range of the present utility model.
