The utility model discloses a novel lithium cell take up case belongs to battery application apparatus field. It includes the open box shell in top, in the inside of box shell through the box baffle with separating into leading groove and back radiator fan mounting groove between the front panel of box shell and the rear panel. The utility model discloses at the in -process of power supply, the application temperature of temperature sensor determine lithium cell. When monitoring the temperature above the default, the control by temperature change unit control radiator fan open, utilizes radiator fan and phase change material to cool down to the lithium cell jointly. And when lithium cell operating temperature misses the default, only utilize the phase change material heat absorption to cool off. Cool off the cooling method who combines together through air cooling, phase change material cooling with the fin, the the normal power supply operation of lithium cell is ensured in automaticintelligent monitoring cooling.
