The present invention relates to the technical field of switch box heat dissipation, and specifically provides a withdrawable switch cabinet with rapid heat dissipation, including a cabinet, wherein a plurality of switch boxes are accommodated, a base frame and a bracket are slidably arranged in the cabinet, and a side frame rotates around the base frame. When a switch box generates more heat, the base frame rises to release the restriction of the side frame to drive the bracket to move upward, thereby driving the switch box to rise, so that the heat dissipation space at the bottom of the switch box is increased. At the same time, an exhaust fan is arranged on the bracket, and the exhaust fan is started, so that the switch box is subjected to dual heat dissipation, one is the heat dissipation of the blowing plate, and the other is the heat dissipation of the exhaust fan. At the same time, the heat dissipation space is increased, so that the switch box with more heat generation can dissipate heat efficiently, and abnormal operation of the switch box is avoided.
