When the battery is disassembled, the baffle 13 is firstly disassembled from the side plate 11, and then the battery is pushed out from the adjacent side of the side plate 11, so that the battery is separated from the restraint of the side plate 11.
The number of the set of baffle plates 13 is related to the inserting direction and the inserting manner of the baffle plates 13, for example, when the set of baffle plates 13 only includes one baffle plate 13, the extending surface of the baffle plate 13 can be perpendicular to the bottom plate 12 and also perpendicular to the side plate 11, and at this time, the baffle plate 13 is preferably inserted downwards from the upper end of the side plate 11; correspondingly, the two ends of the side plate 11 are respectively provided with a groove for inserting the baffle 13. When the number of the group of baffle plates 13 is more than one, the baffle plates 13 can be inserted along the parallel surfaces of the bottom plate 12 and perpendicular to the extending surfaces of the side plates 11, and the baffle plates 13 positioned at the end parts of the two side plates 11 at the same side form a shielding surface with a grid structure together to limit the movement of the battery; correspondingly, the side plate 11 may be provided with a plurality of mounting holes for inserting any of the baffles 13.
Preferably, the baffle 13 in the mounting rack 1 is inserted into the side plate 11 from top to bottom, one end of the side plate 11 away from the bottom plate 12 is provided with a slide way 111 extending towards the bottom plate 12, that is, the length direction of the slide way 111 is vertically arranged, and when the baffle 13 is inserted into the slide way 111, the extending surface of the baffle 13 is perpendicular to both the bottom plate 12 and the side plate 11; on this basis, a plurality of heat dissipation holes 131 can be formed in the baffle 13 to improve the heat dissipation effect of the battery.

Because of the arrangement of the cooling pipe 123, the antifreeze glycol aqueous solution can be used as the cooling medium in the cooling pipe 123, and since the number of turns of the detour pipe 1231 is small and the degree of the turn is small, the flow rate of the antifreeze glycol aqueous solution is stable when the antifreeze glycol aqueous solution flows through the detour pipe 1231, and the temperature uniformity is good.
Furthermore, the battery pack thermal management system provided by the present invention may further include a plurality of mounting frames 1, and all the mounting frames 1 are connected in series to form a cooling circulation loop 3 through the first connection port 121 and the second connection port 122 of each mounting frame 1; the circulation cooling loop 3 is connected to a cooling pump 4.
The above-mentioned serial connection means that all the mounting frames 1 are connected in series with the cooling pump 4, and the mounting frames 1 are connected in series or in parallel or in a combination of series and parallel, and can be reasonably arranged according to the number of the mounting frames 1 and the mounting space.
When a cooling medium, such as an antifreeze glycol aqueous solution, is pumped into the circulating cooling circuit 3 by the cooling pump 4, the antifreeze glycol aqueous solution flows through the bottom plates 12 of all the mounting blocks 1 in sequence to cool the batteries in all the mounting blocks 1. Because a plurality of mounting brackets 1 share one cooling pump 4, and two adjacent mounting brackets 1 are connected through a pipeline, the structural load type of the whole battery pack heat management system is greatly reduced, the space is saved, and the energy consumption is reduced.
Wherein, the heating plate 2 can set up to the square heating plate 2 that the size is not more than the size of curb plate 11, and square heating plate 2 pastes in 11 inner walls of curb plate through heat conduction glue between two parties, starts when the vehicle starts, traveles under cold area or low temperature environment, opens heating plate 2 so that heat the battery to ensure the steady start of vehicle and the duration of guarantee battery.
