Outdoor LED display screen with good heat-dissipating effect

The invention discloses an outdoor LED display screen with good heat-dissipating effect, comprising a housing; a control switch is mounted at the rear of the upper surface of the housing, the front of the upper surface of the housing is fitted with an intake channel, a glass cover is mounted at an opening in the front side of the housing, an upper mounting seat and a lower mounting seat are arranged at the top and bottom of the housing at the inner side of the glass cover in face-to-face manner, a display screen is arranged between the upper mounting seat and the lower mounting seat, heat transfer partitions are distributed evenly in an inner cavity of the housing at the inner side of the display screen, and the heat transfer partitions are U-shaped metal sheets. Heat dissipation is achieved for a PCB (printed circuit board) and the display screen through the intake channel, the heat transfer partitions, a servo motor, a spindle and fan blades; the U-shaped heat transfer partitions divide cavities in front an
