Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
A kind of battery bag with cooled plate, including battery frame, water-cooling cover plate 2, middle beam 4, these parts all adopt aluminium alloy, to alleviate weight.Battery frame includes bottom tray 1, and bottom tray 1 lower surface has convex tendon dividing plate 3, and being shaped as of water-cooling cover plate 2 is U-shaped, and both sides is used for laying the course, and middle fixing middle beam 4, for self-contained battery group.Described convex tendon dividing plate 3 two ends bear against water-cooling cover plate 2 and convex tendon dividing plate 3, intermediate formation water channel, and water channel is roundabout shape, have multiple parallel water channel convex tendon in water channel.
The connected mode of bottom tray 1, water-cooling cover plate and water channel convex tendon dividing plate 3 has two kinds, first water channel convex tendon, water channel dividing plate and pallet 1 integration gravity-assist pouring molding, then welding or bonding water-cooling cover plate 2, as shown in Figures 1 to 4.Adopting gravity to pour into mode integral casting forming, materials'use A356.2 aluminium alloy, water-cooling cover plate adopts cold rolling 6 to be aluminium plate, adopt punching press or cut molding, as adopted punching press, its punching press wall thickness euphotic belt needs to reach more than the 80% of wall thickness, otherwise can affect the weldering welding of follow-up agitating friction.Therefore punching press needs out fine blanking die.Water channel convex tendon and water-cooling cover plate edge adopt agitating friction weldering integral solder molding, adopt that structure glue is cementing is isolated into water channel between water channel convex tendon dividing plate and water-cooling cover plate, it is to avoid side leakage forms eddy current.The step that battery tray water channel convex tendon edge and water-cooling cover plate coordinate needs CNC machine-shaping, and this technique mainly solves two problems.One in order to solve water channel cover plate and water channel fit clearance problem, excesssive gap can cause agitating friction weldering rosin joint, and gap is little causes assembling difficulty.Another is to remove the casting aluminum surface alumina oxide impact on stir friction welding seam quality.
Another kind of processing mode water channel convex tendon, convex tendon dividing plate 3 and pallet 1 split molding, its mode is that water channel convex tendon, convex tendon dividing plate 3 and water-cooling cover plate 2 add man-hour and water-cooling cover plate 2 integrated extrusion molding, and then welding water-cooling cover plate 2 and pallet 1, as shown in Fig. 5 to Fig. 8.Other processing modes are identical.
Main parts size processing technique and key property: battery frame bottom tray: casting deburring CNC processing is cleaned--inspection；Water channel cover plate: blanking punching press (cut)--clean inspection；Intake-outlet water nozzle: melting extruding timeliness Cutting indexes cleans--inspection；Middle beam: melting extruding timeliness Cutting indexes cleans inspection；Battery frame bottom tray, since it is desired that bear the weight of whole battery bag and impact thereof and vibrations, therefore not only needs it to have certain rigidity, with greater need for there being certain toughness.It is thus desirable to need its elongation percentage be more than or equal to 4% during casting；Water channel cover plate and bottom tray need to adopt agitating friction weldering welding, and the Weld Performance of agitating friction weldering welding can reach the 70%-100% of strength of parent.And it is high that it has the uniform weldquality of welding penetration, the features such as technology stability is good.Therefore its intensity and sealing are higher.
Below the preferred embodiment this utility model created has illustrated, but this utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent modification or replacement under the premise without prejudice to this utility model creative spirit, and these equivalent modifications or replacement are all contained in the application claim limited range.
