[0006] The principle of the utility model is that when in use, firstly, the coolant needs to be added into the coolant tank, and then the circulation pump is started to make the coolant be re-delivered to the coolant tank from the delivery pipe, the coil and the return pipe, so that the coolant fills the entire pipeline, and then during the operation of the energy storage cabinet, the heat-conducting seat will absorb the heat of the energy storage cabinet, and the coolant in the coil located in the heat-conducting seat will take away the heat, thereby driving the purpose of liquid cooling of the energy storage cabinet, and the fan will introduce the outside air and blow it on the heat-conducting seat, so that the heat-conducting seat and the coil can be air-cooled to dissipate heat, thereby improving the efficiency and effect of the heat dissipation of the energy storage cabinet; later, the locking pin can be pulled by the shifting block to separate the locking pin from the air inlet tube, so that the air inlet tube can be disassembled, thereby facilitating the later maintenance of the fan.
