Abstract
An air vent structure includes a frame arranged at an air outlet or an air inlet of a box body, and a plurality of plates. In cross section, each of the plates is a bent structure and includes a first flat portion, an upslope portion and a downslope portion. The first flat portion is fixed to the frame and extends in a direction away from the frame, the plate then extending upward to form the upslope portion. A top of the upslope bends downward to form the downslope portion, and the height of the downslope portion is smaller than the height of the upslope portion. The air vent structure can ensure that hot air flow passes smoothly through the air outlet, and also ensure that the hot air flow is blown out in a horizontal direction. A box-type inverter having the air vent structure is also provided.
