Technical solution of the present utility model is to provide a kind of battery cooling plate, including upper plate and lower plate, and upper plate is flat Panel, lower plate is stamped and formed out downwards refrigerant circulation passage, and the reinforcement of multiple optimization refrigerant circulations is also stamped with lower plate, strengthens Muscle is high together with the edge of lower plate, and the surrounding kissing of upper plate and lower plate merges laminating and is welded and fixed, and upper plate is provided with inlet tube and goes out Mouth pipe, inlet tube and outlet penetrate upper plate and coordinate with the refrigerant circulation passage of lower plate.

Using compared with prior art, the utility model has advantages below after above structure：The battery cooling plate structure Simply, by arranging the reinforcement that optimization refrigerant circulates, and reinforcement is high together with lower plate edge, the surrounding kissing of upper plate and lower plate Merge laminating to be welded and fixed, cooling effectiveness is high, so as to more reasonably cool down the battery pack being placed on upper plate.

Preferably, the reinforcement of lower plate is fitted and is welded and fixed with the bottom surface of upper plate.

Preferably, the lower plate is stamped and formed out downwards two symmetrical U-shaped curve-like refrigerant circulation passages, refrigerant circulation Passage is surrounded with the edge of lower plate by stamping forming U-shaped curve-like isolation bar and formed, and two U shape curve-likes refrigerants circulations are logical Road is located at respectively the both sides of lower plate length direction, and the edge of the width of two U-shaped curve-like isolation bar one end and lower plate Offset, the other end separates to form space with the edge of the width of lower plate so that cold in U-shaped curve-like refrigerant circulation passage Matchmaker can converge, and two are corresponding, and the inlet tube of upper plate has two, and two inlet tubes respectively penetrate upper plate and connect with lower plate, and two The penetrating end of individual inlet tube is located at respectively two U-shaped curve-like isolation bars and offsets what is formed with the edge of the width of lower plate At refrigerant circulation passage, the outlet of upper plate is one, and outlet penetrates upper plate and connects with lower plate, and the penetrating end of outlet is located at The refrigerant meet of lower plate.

Further, heat-conducting plate installing hole corresponding with heat-conducting plate is additionally provided with upper plate.

Description of the drawings：

Fig. 1 is upper plate structure schematic diagram of the present utility model.

Fig. 2 is the structural representation of lower plate of the present utility model.

Specific embodiment：

With reference to the accompanying drawings and detailed description the utility model is described in further detail：

As shown in Figure 1, 2, a kind of battery cooling plate, including upper plate 1 and lower plate 2, upper plate 1 is surface plate, and lower plate 2 is to undershoot Swaging is also stamped with the reinforcement 6 of multiple optimization refrigerant circulations into refrigerant circulation passage in lower plate, reinforcement 6 is with along refrigerant Based on circulating direction is arranged, other part reinforcement is then arranged perpendicular to refrigerant circulating direction, but regardless of setting, with not Premised on hindering refrigerant circulation, reinforcement 6 is high together with the edge of lower plate, and the reinforcement of lower plate is fitted and welded with the bottom surface of upper plate The surrounding kissing merging laminating for connecing fixation, upper plate 1 and lower plate 2 is welded and fixed, and upper plate 1 is provided with inlet tube 3 and outlet 4, enters Mouth pipe 3 and outlet 4 penetrate upper plate and coordinate with refrigerant circulation passage.In addition, being additionally provided with corresponding radiating in upper plate 1 and lower plate 2 Through hole 5, thermal vias 5 are arranged near refrigerant circulation passage.In the present embodiment, refrigerant circulation passage includes that refrigerant inflow is logical Road 81 and refrigerant flow pass 82, wherein, lower plate 2 is stamped and formed out downwards two symmetrical U-shaped curve-like refrigerant flow channels 81, Refrigerant flow channel 81 is surrounded with the edge of lower plate by stamping forming U-shaped curve-like isolation bar 7 and formed, and two refrigerants are flowed into and led to Road 81 is located at respectively the both sides of lower plate length direction, and the side of the width of two one end of U-shaped curve-like isolation bar 7 and lower plate Refrigerant is formed along offseting and flows into end 811, accordingly, the inlet tube 3 of upper plate has two, two inlet tubes 3 respectively penetrate upper plate 1 with Refrigerant flows into end 811 and connects, and two other ends of U-shaped curve-like isolation bar 7 separate to form cold with the edge of the width of lower plate Matchmaker flows into merging end 812, and the refrigerant for flowing through two refrigerant flow channels converges in refrigerant inflow merging end；Refrigerant flow pass 82 By above-mentioned two U-shaped curve-like isolation bar and lower plate edge around being formed, wherein, two U-shaped curve-like isolation bars 7 and lower plate The offset blind end to be formed of the edge of width forms refrigerant outflow end 821, and accordingly, the outlet 4 of upper plate is one, is gone out Mouth pipe 4 penetrates upper plate and connects with refrigerant outflow end 821, and the other end and refrigerant of refrigerant flow pass flow into merging end 812 and connect.
