Embodiment
Below first embodiment of the utility model is described.As shown in Figure 2, modular battery 1 possesses a plurality of monocells 2 that discharge and recharge through the work under the high temperature and the thermally insulated container 3 that these monocells 2 are held with upright state.Thermally insulated container 3 possess top opening rectangle box container body 31, stop up the top lid 32 of this container body 31.In addition, in Fig. 1, following Fig. 4 and Fig. 5, omitted demonstration to lid 32.
In addition, as shown in Figure 1, modular battery 1 possesses: fill layer of sand 40, it is disposed at the inner lower of thermally insulated container 3, is made up of the heap sand of the clearance portion that is filled in thermally insulated container 3 and monocell 2; Solidify layer of sand 41, it is disposed at the inner upper side of thermally insulated container 3, and the curing sand through will mixed adhesive forms in heap sand hardens and forms.
The size of container body 31 does not have special qualification, is object with the container about vertical 1000-2000mm * horizontal 1500-2500mm * high 400-700mm usually.Here said monocell 2 is the NaS battery, uses the NaS battery of the class drum about external diameter
height 400-540mm usually.Monocell 2 is erect the method that is provided with does not have special qualification, and preferably, the side of the monocell 2 of type of making drum contacts with each other, and the most thickly fills with the maximum mode of number of erectting the monocell 2 that is provided with on the per unit area.The number of erectting the monocell 2 that is provided with is different and different because of the size of thermally insulated container 3 and monocell 2, the aligning method of monocell 2 etc.; Under the situation of in the thermally insulated container 3 of said common size, likewise the monocell 2 of common size being filled with the closeest mode, just can erect the monocell 2 of 45-432 about individual is set.This moment outermost monocell 2 and container body 31 medial surface between clearance portion, its width about 0-15mm, lid 32 the insides and above the monocell 2 between clearance portion, its height is about 10-20mm.In addition, the clearance portion of the utility model is meant the clearance portion under the state that holds monocell 2 in the thermally insulated container 3, particularly, as shown in Figures 2 and 3, comprising: clearance portion 51, and it is formed between the side of medial surface and monocell 2 of container body 31; Clearance portion 52, it is only formed by the side of monocell 2; Clearance portion 53 etc. are between it is formed on above the inside and the monocell 2 of lid 32.
As shown in Figure 2, the inner bottom surface of container body 31 lays padded coaming 61, electric heater 62, stiffener 63, electric insulation through lamination and constructs with mica sheet 64.In addition, also post electric insulation with mica sheet 65 at lid 32 inner faces.
As heap sand, preferably use thermal endurance, corrosion resistance and electrical insulating property excellent carborundum, aluminium oxide, the shot-like particle of silica sand, ceramic particle (crushed material of porcelain insulator) equigranular thing, preferably its average grain diameter is 0.2-1.5mm.If the average grain diameter of heap sand is too small, heap sand is invaded the bottom surface side of monocell 2 easily, and is not preferred from this point, if excessive, mobile variation, it is difficult, not preferred in this that the filling of heap sand becomes.
In addition, as shown in Figure 1, the scope of solidifying the short transverse of layer of sand 41 is merely from monocell 2 above the part (part of the height h1 of Fig. 1) below the 1/5-1/15 of length H of monocell 2.As solidifying layer of sand 41 employed adhesives; Room temperature vulcanizing property resin thermal endurance, resistance to water and excellent corrosion resistances such as thermosetting resin, silicone rubber kinds resin, phenolic resin, alkoxide resinoid such as for example preferred inorganic bond (boric acid-metal oxide-anhydrous boron acids), polyimide based resin, silicon resinoid, thus preferred.
Research according to the inventor; Can know; If possess the layer of sand 41 of curing near near the position of the certain height so only in the clearance portion between monocell 2 and thermally insulated container 3, above the monocell 2; Even the heap sand that is filled in other clearance portion is by sclerosis and be in the state that can flow, also can fixes and keep the setting of monocell 2 that state is set and can be prevented the mutual needed intensity of offset of monocell 2.
In addition, be limited to said specific part through only solidifying layer of sand 41, the use amount that just can will mix the heap sand of high price adhesive is reduced to about existing 1/2-1/5, and the result just can significantly reduce the manufacturing cost of modular battery 1.In addition, find that the result of the use amount of reduction adhesive, the moisture incidences that also have in the heatproof container 3 reduce, and the effect of electrical insulating property raising.
In addition; Why will solidify layer of sand 41 is arranged to make it above monocell 2, to arrive to the ad-hoc location of the below of monocell 2; Be arranged to make it to arrive extremely than this ad-hoc location if be because will solidify layer of sand 41 more near the position of the bottom of thermally insulated container 3; Dehydration variation in the time of can causing the adhesive sclerosis, electrical insulating property reduces.In addition; The height h1 that why will solidify layer of sand 41 is made as the 1/5-1/15 of the length H of monocell 2; If be because the not enough H of h1 1/15, then be difficult to obtain to the fixing enough intensity of monocell 2, on the other hand; If h1 surpasses 1/5 of H, then the main purpose of the utility model effect that reduces cost and the effect that reduces moisture weakens.In addition, the weight ratio of preferred consolidation sand and heap sand is 1: 10-1: 30.Can not get enough intensity if weight ratio, is then solidified layer of sand 41 less than this scope, in addition, if weight ratio greater than this scope, then the effect that reduces of cost and the effect of moisture minimizing die down.
In addition, need satisfy the relation of following formula (1) between the bulk density P of the filling layer of sand 41 of modular battery 1 and the volume of ideal density Pi.
0.98Pi≤P...(1)
In advance; Even so that modular battery 1 is applied vibration; The bulk density of the degree that the bulk density of heap sand also can not uprise again closely fills heap sand, prevent thus to vibrate floating and offset of caused monocell 2, and the packed height of heap sand changes.
In this manual; Volume of ideal density Pi is meant; Clearance portion in holding the box-shaped thermally insulated container 3 of monocell 2 is filled under the state of heap sand, when the acceleration that thermally insulated container 3 is applied 0.3G with horizontal direction vibrates it in the horizontal direction, and the bulk density of the value of reaching capacity.
From above-mentioned viewpoint, preferably the bulk density P with heap sand is that volume of ideal density Pi fills, and just can obtain same effect but 0.98Pi is above, thereby bulk density P is also passable more than desirable bulk density Pi.This is because the saturation value that volume of ideal density Pi only is acceleration with 0.3G eventually when applying vibration is not real saturated volume density, therefore, also can produce the situation that bulk density further rises when applying the vibration above 0.3G.In addition, usually, the bulk density P of heap sand is at 1.2-1.6g/cm
3Scope.The weight of the heap sand of filling usually in addition, is 600-1100kg.
In addition, in the modular battery 1 of the utility model,, also need cover the outstanding splicing ear 21 that is arranged at each monocell 2 top fully with heap sand except filling the layer of sand 40 with above-mentioned bulk density.This is owing to there is following situation: even bulk density is abundant; If splicing ear 21 exposes, near the then corrosion easily heap sand laminar surface, in addition; Stress puts on splicing ear 21 owing to the thermal cycle in battery operated, thereby the durability of splicing ear 21 reduces.
As the method for the bulk density P that obtains such heap sand, can adopt following vibration operation.Fill in the operation of heap sand in the clearance portion in the thermally insulated container that holds monocell 23, thermally insulated container 3 is applied the acceleration of horizontal direction, filling heap sand when thermally insulated container 3 vibrate in the horizontal direction.Through thermally insulated container 3 being applied the acceleration of horizontal direction, just can when suppressing the floating of monocell 2, closely and equably fill heap sand.
When manufacturing module battery 1; Monocell 2 is contained in after the thermally insulated container 3, at first, fills heap sand to clearance portion from thermally insulated container 3 bottoms; Make thermally insulated container 3 vibration, above monocell 2, form thus and fill layer of sand 40 to the position of the 1/5-1/15 below of the length H of monocell 2.In addition, above that clearance portion fill mixed adhesive curing sand above monocell 2., thereby through heat wait make adhesive sclerosis form curing layer of sand 41, monocell 2 is provided with state maintenance and fixing with setting thereafter.In addition, on the curing layer of sand 41 of sclerosis like this, further apply also unhardened heap sand, lid 32 and sealing are installed on container body 31.
Then.Second embodiment to the utility model describes.As shown in Figure 4; The modular battery 11 of this embodiment is compared with first embodiment; The position of solidifying layer of sand 42 is different, only possesses curing layer of sand 42 in the part (part of the height h2 of Fig. 4) above the 1/5-1/15 of monocell 2 length H from monocell 2 above.
In addition, as shown in Figure 5, in this embodiment, solidify the scope of the horizontal plane direction of layer of sand 42, be merely outer peripheral portion near thermally insulated container 3 sidewalls.More specifically; Solidify layer of sand 42 and form the frame type of overlooking the mouth word shape that comprises pair of long edges and pair of short edges; The wide Y1 of pair of long edges frame separately is the pair of sidewalls 1/5-1/30 of X1 at interval of the thermally insulated container 3 parallel with pair of long edges, and the wide Y2 of pair of short edges frame separately be the 1/10-1/50 at the pair of sidewalls interval of the thermally insulated container 3 parallel with pair of short edges.To solidify layer of sand 42 like this and form to overlook and be mouthful shape of word shape, and can reduce the use amount of adhesive, and the dehydration when making the adhesive sclerosis improves.
When making the modular battery 11 of this embodiment, monocell 2 is contained in after the thermally insulated container 3, at first, fill heap sand to clearance portion from thermally insulated container 3 bottoms, make thermally insulated container 3 vibrations, form thus and fill layer of sand 40 above monocell 2.In addition, the clearance portion above monocell 2 uses the anchor clamps of regulation shape to fill fixedly sand with mouth word shape, makes height (thickness) h2 of its 1/5-1/15 that reaches monocell 2 length H., through heating etc. make curing layer of sand 42 sclerosis, monocell 2 is provided with state maintenance and fixing with setting thereafter.In addition, apply also unhardened heap sand, lid 32 and sealing are installed on container body 31 in layer of sand 42 area surrounded that are cured.
In the modular battery 11 of this embodiment, also can obtain fixing and keep the setting of monocell 2 that state is set and prevent the needed intensity of offset that monocell 2 is mutual.In addition, be limited to said specific part through only solidifying layer of sand 42, the use amount that just can will mix the heap sand of high price adhesive is reduced to about existing 1/2-1/30, and the result just can significantly reduce the manufacturing cost of modular battery 11.In addition, find the result of the use amount of reduction adhesive, the moisture incidences that also have in the heatproof container 3 reduce, and the effect of electrical insulating property raising.
In addition; The reason of 1/5-1/15 of length H that the height h2 that why will solidify layer of sand 42 is made as monocell 2 is identical with first embodiment, be because, if h2 is less than 1/15 of H; Then be difficult to obtain the fixedly enough intensity of monocell 2; On the other hand, if h2 surpasses 1/5 of H, then the effect that reduces cost as the main purpose of the utility model weakens with the effect that reduces moisture.
