At the same time, the mounting frame 602 can be adjusted by sliding the screw rod 601 is moved to the outside of the cabinet, thereby achieving the effect of adjusting the spatial layout inside the cabinet and facilitating the maintenance of internal devices. The negative pressure air fan 701 is used to introduce external air into the energy storage control cabinet 1 to increase the air exchange rate, and the heat conduction plate 702 on the rear wall of the cabinet and the heat dissipation fin group 705 on the right wall of the cabinet are used to accelerate the heat dissipation and discharge.
