Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figures 1 to 3, a kind of lithium battery case with attemperating unit, comprise casing 9 and attemperating unit, described casing 9 is provided with box cover 10, in described casing 9, upper surface is provided with upper holder 16, in described casing 9, lower surface is provided with base plate 5, described base plate 5 is provided with lower fixed frame 20, cushion pad 12 is covered with between described base plate 5 and lower fixed frame 20, battery pack 6 is placed with between fixed frame 16 and lower fixed frame 20, fixed frame 16 is spaced apart uniformly by battery pack 6 with lower fixed frame 20, fixed frame 16 and lower fixed frame 20 are respectively top pipe holder and below pipe holder, in described casing 9, the middle part of battery pack 6 is also provided with central dividing plate 3, the front-end and back-end of described battery pack 6 are respectively equipped with top board 17 and lower platen 4, insulating press boards 2 and lower insulating press boards 11 is respectively equipped with between described top board 17 and battery pack 6 and between lower platen 4 and battery pack 6, insulating press boards 2 and lower insulating press boards 11 in utilization, from top, battery pack 6 is pressed in battery case, simultaneously form closed air channel between the upper holder 16 of battery pack 6 and lower fixed frame 20, be convenient to air flowing, also be provided with for the protective plate 15 of separate batteries group 6 with attemperating unit in described casing 9, described attemperating unit comprises BMS system 1 and heater 18, described protective plate 15 is provided with described BMS system 1, the sidewall of the described casing 9 near protective plate 15 side is also provided with air outlet successively, cable locking head 7 and air inlet, be positioned at air outlet place in described casing 9 and be provided with cooling fan 19, described air inlet and air outlet place are equipped with screen pack 13, be positioned at air inlet in described casing 9 and be provided with air inlet baffle plate 14, air outlet is positioned at and air inlet is also respectively equipped with air outlet protective hood 8 and air inlet guard shield 21 outside described casing 9, the guard shield that the air inlet of casing 9 and air outlet place are provided with and screen pack 13, to guarantee the IP grade of product, can not intake easily, enter dirt, also heat-insulation layer is posted at the inwall of described casing 9, ensure that the temperature in casing 9 can not be subject to external influence easily, described BMS system 1 is connected with cooling fan 19 with heater 18 respectively.
