The invention relates to the technical field of engineering machinery, and provides a water cooling system for a high-voltage electric forklift and the high-voltage electric forklift. The water cooling system for the high-voltage electric forklift comprises a refrigerant loop, a secondary refrigerant loop and a first cooling loop; the refrigerant loop comprises a compressor, a condenser, an expansion valve and an evaporator which are connected in sequence; the secondary refrigerant loop is used for circulating a secondary refrigerant, the secondary refrigerant comprises a first power pump and a first containing box used for storing the secondary refrigerant, and the first containing box is connected to the evaporator through the first power pump; the first cooling loop is directly connected to the first containing box, a heat exchanger and a second power pump are arranged on the first cooling loop, the heat exchanger is used for heat exchange between the secondary refrigerant and the power battery and/or the motor, and the second power pump is arranged to be capable of driving the secondary refrigerant to circulate in the first cooling loop. Through the arrangement, the cooling problem of the high-voltage electric forklift in the prior art is solved.

    本发明涉及工程机械技术领域,提供一种用于高压电动叉车的水冷系统及高压电动叉车,其中,用于高压电动叉车的水冷系统包括制冷剂回路、载冷剂回路和第一冷却回路,制冷剂回路用于供制冷剂循环流通,制冷剂回路包括依次连接的压缩机、冷凝器、膨胀阀和蒸发器;载冷剂回路用于供载冷剂循环流通,载冷剂包括第一动力泵和用于储存载冷剂的第一容纳箱,第一容纳箱通过第一动力泵连接于蒸发器;第一冷却回路直接连接于第一容纳箱,第一冷却回路上设置有换热器和第二动力泵,换热器用于供载冷剂与动力电池和/或电机进行热交换,第二动力泵设置为能够驱动载冷剂在第一冷却回路内循环流通。如此设置,解决了现有技术中的高压电动叉车的降温冷却的问题。
