In the present embodiment, battery housing box 22 adopts 4 sections, is accommodated with 6 storage batterys 11 in each battery housing box 22, thus constitutes the battery pack 10 being accommodated with 24 storage batterys 11.But be not limited in this structure, hop count or the storage number of battery housing box 22 can both carry out suitable change.In addition, the structure of each battery housing box 22 is identical.
Fig. 2 is the figure observing battery housing box 22 from front, and Fig. 3 is the figure from top view.
Battery housing box 22 possesses: base plate 23; Spaced apart and be configured in the upper plate 24 of the top of base plate 23; To the side plate 25 of the pair of right and left connected between base plate 23 and the left and right end portions of upper plate 24; With rear plate 30, this battery housing box 22 forms the box-formed shape with front openings incorporating section 22A (Fig. 2) of front openings.The each plate 23 ~ 25 forming this battery housing box 22 is made by the metallic plate of iron or stainless steel etc.In addition, the position relative with the slit 31A set by pressing plate 31 described later in the rear on plate 30 can form the slit of same shape.By forming this slit, can ventilate front and back, and the heat of the storage battery 11 from left and right can be discharged into outside effectively.
Storage battery 11 is the control valve type storage batterys for stand-by power supply etc., and it possesses: the electric groove 12 of rectangular shape containing electrode, electrolyte; With the electric groove lid 13 of the front portion of this electric groove 12 of formation.Electricity groove 12 forms the structure not possessing reinforcement.In addition, on electric groove lid 13, positive terminal 15A, negative terminal 15B and control valve 15C are installed.In addition, in the following description, when not needing intended distinction positive terminal 15A, negative terminal 15B, terminal 15 is all denoted as.
This storage battery 11 is encased in battery housing box 22, makes to be provided with the front of electric groove lid 13 towards battery housing box 22 of terminal 15 grade, and become the state of more forwards stretching out than battery housing box 22.Like this after enclosing storage battery 11, pressing plate (also referred to as retainer) 31 is fixed on the front portion of battery housing box 22.
As shown in Figure 2, on the base plate 23 that each pressing plate 31 is fixed on battery housing box 22 by the secure component 32 of upper and lower a pair and upper plate 24, and extrude each storage battery 11 from front, when common use, storage battery 11 can not come off from battery housing box 22.
When using battery pack 10, the terminal 15 of each storage battery 11 becomes and carries out by conductor and connecting plate 33 (with reference to Fig. 1) state that is electrically connected.The storage battery 11 of necessary number, by connecting the terminal 15 of adjacent storage battery 11, is connected in series or parallel by connecting plate 33, forms thus " battery pack " of the capacity that ensure that necessary voltage or necessity.
In addition, in FIG, show connecting plate 33 to be formed by copper coin and situation about being connected in series storage battery 11.Connecting plate 33 is not limited to copper coin, also can use other metallic plate or connect up other conductors such.
As shown in Fig. 1 or Fig. 3, in battery housing box 22, be provided with the dividing plate and multiple central baffle 41 that the accommodation space of storage battery 11 are carried out left and right separation.In the example shown in Fig. 1 ~ Fig. 3, be alternately configured with storage battery 11 and central baffle 41, when storage battery 11 is 6, be provided with 5 central baffle 41.
As shown in Fig. 1 or Fig. 3, central baffle 41 has blank part S in inside, this blank part S is communicated with the slit 51,52 (about 52 with reference to following accompanying drawing) set by upper plate 24 and base plate 23, forms vent passage (peristome) 55 thus between the storage battery 11 of left and right.The heat of the storage battery 11 from left and right can be discharged into outside effectively by this vent passage 55.
Fig. 4 represents the stereogram of central baffle 41.Central baffle 41 has: the side plate 42 of pair of right and left; Only with predetermined distance, these side plates about 42 are separated and the multiple union bodies 43 linked these side plates 42.
The shape of the side plate 42 of left and right is identical, and the rectangular plate shape that formation and the side (being equivalent to the face relative with storage battery 11) of the storage battery 11 of left and right are same shape.
Union body 43 links the side plate 42 of left and right in the mode of the spaced apart blank part S of the side plate 42 in left and right, and makes blank part S open wide in upper and lower and front and back.More specifically, union body 43 forms the thin plate shape extended in left-right direction, to become, the independent beam linked is carried out to four relative angles of the side plate 42 of left and right, the peristome of formation up and down KA, KB between the side plate 42 of left and right, and form peristome KC, KD in front and back.
As long as above-mentioned central baffle 41 is formed by the material that thermal conductivity is high, can be formed by the metallic plate identical with battery housing box 22, also can use the various metal material or resin etc. of copper, aluminium alloy, magnesium alloy etc.In addition, also can use extrinsion pressing, die cast process or blow molding method etc. and be shaped to central baffle 41.
When central baffle 41 is configured in battery housing box 22, as shown in Figure 3, upper and lower peristome KA, KB of central baffle 41, be communicated with the slit 51,52 set by upper plate 24 and base plate 23.Thus, forming the vent passage 55 for making free air circulation up and down, can by the thermal release of the storage battery 11 from left and right to top.
In addition, as shown in Figure 2, the peristome KC in the front of central baffle 41, is communicated with the slit 31A be arranged on pressing plate 31.Thus, can also by the thermal release of the storage battery 11 from left and right to front.Here, because the current density of storage battery 11 easily uprises in electric this side of groove lid 13 being provided with terminal 15 grade, so compared with rear side, the temperature of front side more easily raises.In this configuration, because central baffle 41 can forwards release heat, so the front side of storage battery 11 and the temperature difference of rear side can be reduced, and the equalization (evenly heating) of the temperature of storage battery 11 self can be realized.
In addition, shape due to battery housing box 22 is front openings and closes below, and therefore when central baffle 41 is encased in battery housing box 22, the heat of the rear side of storage battery 11 is difficult to distribute, even if like this, be also conducive to the cooling of storage battery 11 and the evenly heating of front and back temperature.But, in the situation etc. wanting to promote heat radiation further, also can carry out the various changes making the back face aperture of the battery housing box 22 of the part of loading central baffle 41 such.
Anterior-posterior length (anterior-posterior length of=side plate) LA (with reference to Fig. 4) of this central baffle 41, form the length roughly the same with depth (anterior-posterior length) L1 of battery housing box 22 (with reference to Fig. 3), the height H A (height of=side plate 42) of central baffle 41, forms the length roughly the same with the separating distance H1 (with reference to Fig. 2) between the base plate 23 of battery housing box 22 and upper plate 24.Thus, central baffle 41 is erected with the state be clamped between the base plate 23 of battery housing box 22 and upper plate 24, left and right is carried out to the inner space (front openings incorporating section 22A) of battery housing box 22 and separates.In addition, central baffle 41 is with easy access along front and back from the front openings incorporating section 22A of battery housing box 22, and horizontally slipping freely along base plate 23 or upper plate 24.
Therefore, it is possible to be easy to regulate the position of central baffle 41 to match to make the right position of itself and storage battery 11, as shown in FIG. 1 to 3, configuration central baffle 41 can be easy to very close to each other to make between itself and storage battery 11.By this configuration, the side plate 42 of the left and right of central baffle 41 carries out close contact with the side of the storage battery 11 of left and right (both sides are adjacent), and the heat of storage battery 11 is discharged in blank part S via side plate 42.
In addition, as shown in Figure 3, slit 51 set by upper plate 24 is, the rectangular hole shape that fore-and-aft direction is longer, and form following shape: its width (left and right length) WS is less than or equal to the width W A of the upper and lower blank part S of central baffle 41 and its anterior-posterior length LS is less than or equal to the anterior-posterior length LA of central baffle 41.Therefore, even if the position of central baffle 41 slightly offsets in left and right or front and back, each slit 51 being arranged on upper plate 24 also can be made to be communicated with blank part S, described blank part S opening wide up and down along each central baffle 41.In addition, about the slit 52 be arranged on base plate 23, also identical with above-mentioned slit 51.
In addition, when overlapping with multistage battery housing box 22, as shown in Figure 1, between upper and lower battery housing box 22, left and right is formed continuously and the spatial portion be communicated with extraneous gas.Therefore, by the ventilation in blank part S, between upper and lower battery housing box 22, also extraneous air can be siphoned away.Thus, the heat between upper and lower battery housing box 22 can be discharged effectively via blank part S, and can improve the radiating effect of storage battery 11.Like this, the ventilation of the air-flow produced because of the heating of storage battery 11 can be promoted, and the thermal diffusivity of storage battery 11 can be improved.
And, in the present embodiment, except the raising of thermal diffusivity, in order to reduce the deviation (heat radiation is uneven) of the temperature of each storage battery 11, between the storage battery 11 of regulation, only form above-mentioned vent passage 55 to promote heat radiation, suppress heat radiation inequality not formed between remaining storage battery 11 towards the mode of the vent passage 55 of upper and lower and/or front and back.
