The motor 5 is installed on the frame 6 of the electric forklift, the water tank 2 is installed above the motor 5 through a water tank support 7, and the bottom of the water tank is of an inwards concave arc-shaped structure 21. In order to fully utilize the heat generated by the motor 5 of the electric forklift in the running process, when the electric forklift works in a low-temperature environment, the bottom of the water tank is in a concave arc structure 21 consistent with the arc line of the shell of the motor 5, and the water tank is installed close to the motor 5 as much as possible while the operation of the motor 5 is not influenced.

The storage battery pack 1 is internally provided with a plurality of battery bodies 13 arranged in a matrix, and the water circulation pipeline 14 is attached to the outer surfaces of the battery bodies 13. The number of layers and the length of the water circulation pipeline 14 arranged outside the battery body 13 can be designed according to the size of the battery body 13, so that each battery body 13 in a low-temperature environment can keep a certain temperature, and the purposes of improving the battery activity and ensuring good charging and discharging performance of the battery are achieved.

The outer side of the battery body 13 is provided with a three-way pipe 11 and/or a four-way pipe 12 for stably positioning the water circulation pipeline 14. The water circulation pipeline 14 penetrates through the three-way pipe 11 and/or the four-way pipe 12 arranged on the outer side of the battery body 13, the three-way pipe 11 and the four-way pipe 12 can play a certain stabilizing role in the pipeline, and the water circulation pipeline 14 is prevented from being squeezed by batteries caused by shaking during operation of the electric forklift.
