In figure: 1, metal shell 11, louvre 2, soft pack cell 21, lug 3, fin 31, limit, left side 32, right edge 33, elongated hole 4, bonding pad 41, left in conjunction with pack 42, right bonding pad group 5, endothermic tube 6, radiating tube 7, sinter layer is installed.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 1, a kind of lithium ionic cell module radiator structure, comprise the metal shell 1 with louvre 11 and the some soft pack cells 2 be disposed side by side on from front to back in metal shell, soft pack cell is roughly rectangular, and the upside of soft pack cell arranges the lug 21 be made up of anode ear and negative electrode lug.In order to effectively distribute the heat that lithium ionic cell module operationally produces, we need to plug between adjacent two soft pack cells to put fin 3, fit with two, front and back soft pack cell respectively in former and later two surfaces of fin, thus make to have sufficient contact area between soft pack cell and fin, so that the heat that soft pack cell produces can be delivered on the fin of both sides, front and back effectively.In addition, we also need to arrange bonding pad 4 respectively on the limit, left side and right edge of fin, and the sidewall of this bonding pad and metal shell fits.Like this, the heat accumulating in soft pack cell inside during lithium ionic cell module work is outwards delivered on bonding pad by fin, bonding pad transfers heat to the metal shell with its laminating on the one hand, thus outwardly dispelled the heat by metal shell, transfer heat to the air of gap between metal shell and soft pack cell on the other hand, the air be heated can discharge heat radiation from the louvre of metal shell, thus the inner heat produced when effectively can distribute lithium ionic cell module work, be conducive to the steady operation of battery, and improve its useful life.Due to fin be connected with bonding pad after be coated on the outside of soft pack cell, be thus conducive to the protection to soft pack cell, avoid soft pack cell to lose efficacy because of damaged.
In addition, can be connected in the following way between fin and bonding pad, particularly, fin can be made into the rectangle roughly the same with soft pack cell, thus make it have parallel limit, left side 31 and right edge 32, the bonding pad be wherein arranged on the limit, left side of odd number fin adjacent from front to back and even number fin links into an integrated entity, and the bonding pad be arranged in the right edge of even number fin adjacent from front to back and odd number fin links into an integrated entity, thus fin and bonding pad are connected into join end to end and the integrative-structure of back and forth bending.As shown in fig. 1, on the left of being arranged on 1st and the 2nd fin and on the 3rd and the 4th fin, the bonding pad on limit links into an integrated entity, and the 2nd and the 3rd fin are arranged on are linked into an integrated entity by the bonding pad of side, thus fin and bonding pad are connected into join end to end and the integrative-structure of back and forth bending.Certainly, perhaps the unsettled side of head and the tail two fin correspondingly arranges the bonding pad fitted with metal shell.Like this, good for radiating effect strip aluminium sheet or copper coin can be obtained fin and the bonding pad of above-mentioned integrative-structure by panel beating Bending Processing mode by us, thus be conducive to reducing manufacturing cost, and the left and right sides of every a slice fin is all connected with bonding pad, is therefore conducive to the uniformity of radiating effect.Owing to only having side to be connected by bonding pad between adjacent two panels fin, and can open like a cork between another relative side, therefore during assembling, soft pack cell can load in the space between two fin easily.
Further, we also can be obliquely installed the endothermic tube 5 of vacuum on a heat sink, and on bonding pad, vertically arrange the radiating tube 6 of vacuum, the endothermic tube one end on fin is connected with the radiating tube on the bonding pad being connected this fin simultaneously.Conveniently process, as shown in Figure 2, endothermic tube and radiating tube can adopt flat square tube, correspondingly arrange on a heat sink simultaneously and install elongated hole 33, endothermic tube can be welded on symmetrically to be installed in elongated hole, thus the soft pack cell being conducive to both sides transfers heat to endothermic tube.Radiating tube then can be welded on the inner side of bonding pad, so that the heat of radiating tube passes to metal shell rapidly by bonding pad.Radiating tube is vertically arranged, endothermic tube is downward-sloping to another free end from being connected one end with radiating tube, and it is contrary with the incline direction of the endothermic tube on the fin being arranged on even number to be arranged on the incline direction of the endothermic tube on the fin of odd number.As shown in fig. 1, the endothermic tube on the 1st, the 3rd fin is communicated with the radiating tube on the bonding pad in left side, and downward-sloping from left to right; And the endothermic tube on the 2nd, the 4th fin is communicated with the radiating tube on the bonding pad on right side, and downward-sloping from right to left.In addition, in endothermic tube, be filled with cold-producing medium, the inner side tube wall of endothermic tube and radiating tube arranges sinter layer 7.Like this, endothermic tube makes the cold-producing medium of its inside flash to gaseous state after the heat absorbing soft pack cell, and the cold-producing medium of gaseous state enters radiating tube on bonding pad and cools and condense into liquid.Because the sinter layer on the inner side tube wall of endothermic tube and radiating tube has a large amount of small pores, thus can form capillarity, therefore, being condensed into liquid cold-producing medium can be back in endothermic tube under the capillarity of sinter layer.So move in circles, when lithium ionic cell module can be worked, the inner heat produced outwards distributes rapidly, thus improves cooling effect further.Be understandable that, we can arrange many endothermic tubes on a heat sink abreast, and many endothermic tubes are connected with a radiating tube simultaneously, thus are conducive to increasing heat absorption efficiency.
Certainly, also following different modes can be adopted between fin and bonding pad to be connected, particularly, fin can be made into the rectangle roughly the same with soft pack cell, thus make it have parallel limit, left side and right edge, as shown in Figure 3, the bonding pad on the limit, left side of the fin of odd number is interconnected to form left bonding pad group 41, and the bonding pad in the right edge of the fin of even number is interconnected to form right bonding pad group 42.That is, limit, left side and the left bonding pad group of the 1st, the 3rd fin link into an integrated entity, and the right edge of the 2nd, the 4th fin and right bonding pad group link into an integrated entity, thus the contact area of dissipation of bonding pad and metal shell can be increased significantly, be conducive to improving radiating effect.Now, the cross section of the connector of the fin of odd number and the cross section of connector of left bonding pad group and the fin of even number and right bonding pad group is all in comb shape, and the connector mutual dislocation of two comb shapes is to inserting, therefore be both convenient to connector by aluminium alloy extruded technological forming, facilitate again the assembling of soft pack cell and fin.
Now, we still can be obliquely installed the endothermic tube of vacuum on a heat sink, the radiating tube of vacuum is set respectively simultaneously in left bonding pad group and right bonding pad group, endothermic tube one end on the fin of odd number is connected with the radiating tube in left bonding pad group, and the endothermic tube one end on the fin of even number is connected with the radiating tube in right bonding pad group.Radiating tube is vertically arranged, endothermic tube is downward-sloping to another free end from being connected one end with radiating tube.Certainly, endothermic tube domestic demand charging refrigerant, the inner side tube wall of endothermic tube and radiating tube arranges sinter layer.And fin can arrange many endothermic tubes abreast, and many endothermic tubes are connected with a radiating tube, thus are conducive to increasing heat absorption efficiency simultaneously.
