    • A discharge system of a stored energy for a construction machine is provided, which includes the energy storage, an electric discharge device discharging energy stored in the energy storage, and an energy cooling portion increasing the heat dissipation capacity of the electric discharge device by cooling heat generated in the electric discharge device for a time when the energy stored in the energy storage is discharged to the electric discharge device. Since the heat generated in the electric discharge device is cooled by a cooling device while the energy stored in the energy storage is discharged to the electric discharge device, the heat dissipation capacity of the electric discharge device is increased to shorten the discharge time. Also, the operation period of the cooling device is controlled in proportion to the residual voltage of the energy storage, and thus the cooling efficiency is maximized.
    • 提供一种用于建筑机械的储能的放电系统,其包括能量存储器,放电储存器中存储的能量的放电装置,以及通过冷却热量增加放电装置的散热能力的能量冷却部 在存储在能量存储器中的能量被放电到放电装置的时间内,在放电装置中产生。 由于在放电装置中产生的热量通过冷却装置冷却,而储存在能量存储器中的能量被放电到放电装置,所以放电装置的散热能力增加以缩短放电时间。 此外,冷却装置的运转期间与能量储存器的剩余电压成比例地控制,从而冷却效率最大化。
