Battery discharge device, cooling control method thereof and discharge mechanism

The invention relates to a battery discharging device, a cooling control method thereof and a discharging mechanism. The discharging mechanism comprises a discharging box body, a cooling conveying plate and a cooling suction plate. A battery and discharge particles are placed in a discharge cavity from a discharge port of a discharge box body, a cooling conveying plate and a cooling suction plate are both located in the discharge cavity and are oppositely arranged at intervals, and during cooling, airflow containing heat-conducting and electric-conducting powder is conveyed to a cooling conveying channel in the cooling conveying plate; and the air flow is blown between the battery and the discharge particles through the first vent holes in the inner surface of the cooling conveying plate. Meanwhile, the heat-conducting and electric-conducting powder is absorbed from the second vent holes through the cooling suction plate, so that the heat-conducting and electric-conducting powder circulates in the direction f
