Abstract: In order to solve the problem of the uniformity of the air circulation, improve the temperature uniformity in the box, and reduce the condensation of the glass door, studies and analyzes the air duct structure based on the horizontal glass door air-cooled display cabinet. An air supply scheme is designed that adopts the basic airflow organization form of air outlet from the upper part of both sides and return air from the lower right side. The air duct structure was optimized by Fluent, and the influence of parameters such as the arrangement of the air outlet and the outlet angle of the air outlet on the temperature uniformity in the box was studied and analyzed. An air supply scheme is obtained that satisfies the temperature uniformity in the box not to exceed 2°C and the proportion of condensation area of the glass door not higher than 5%.

Key words: Horizontal glass door air-cooled display cabinet, Temperature uniformity, Air duct structure
