Abstract
A display apparatus is provided. The display apparatus comprises an electronic display assembly, a heat exchanger, a fan, and a cleaning device. The heat exchanger comprises one or more internal heat dissipation pathways and one or more external heat dissipation pathways. The one or more internal heat dissipation pathways are thermally coupled to the electronic display assembly and the one or more internal heat dissipation pathways are thermally coupled to the one or more external heat dissipation pathways. The fan generates ambient air flow passing through the one or more external heat dissipation pathways. The cleaning device is connected to the one or more external heat dissipation pathways, and used for injecting a cleaning fluid into the one or more external heat dissipation pathways.
