[0011] Air outlets are opened on both sides of the trapezoidal air duct, and an inner guide plate is arranged on the inner side of the air outlet. The inner guide plate is arranged obliquely, and a baffle is arranged on the lower surface of the inner guide plate to guide the hot air to the air outlet for exhaust. At the same time, a heat sink is installed on the air outlet, and heat dissipation holes are arranged on the heat sink, so that the hot air is blown out evenly through the heat dissipation holes, and the wind speed is slowed down to avoid excessive wind speed from blowing away powder on the workpiece; the inclination angle of the inner guide plate can also be changed by adjusting the angle of the guide angle plate, and the air outlet angle and air volume can be adjusted, so that the furnace temperature has better adjustability.
