Abstract: The top-outlet wind air conditioner outdoor unit electric control box as the research object, and conducts verification on its thermal and waterproof performance. During the repeated trial and error process of the original electric control structure, the paper analyzes and summarizes the disadvantages of the original electric control design in terms of heat dissipation and waterproofing. By conducting a retrospective analysis based on the overall electric control layout, a new electric control scheme is proposed, and the revised scheme is retested. The scheme has successfully solved the original thermal and waterproof problems of the top-outlet wind air conditioner, and the revised scheme has certain referencevalue for the subsequent design of top-outlet wind type products.
