Abstract
The invention relates to the technical field of freezers, particularly to a damping stepped air curtain structure of a freezer. By the use of the damping stepped air curtain structure, gradient change form of cold air speed at an air outlet of the freezer is changed, and the problem of increased cooling power caused by the fact that the cold air at the air outlet entrains the outside hot air of the conventional freezer is solved. A first choke plate and a second choke plate laterally arranged in a cold air channel. After arrived in the first choke plate, most part of the cold air flows downward along a free end of the first choke plate, and the rest of the cold air penetrates a through hole in the first choke plate and then flows toward the second choke plate, with flowing downward after stopped by the second choke plate to reduce the air speed. At the air outlet of the cold air channel, the cold air speed size becomes a parabolic form, with the minimum cold air speed on the outside of the air outlet. In this way, the outside hot air is less prone to entrainment into the freezer so as to avoid increase in cooling power of the freezer.
