An improved structure for a dryer duct, in which a center of the duct is an air intake channel; a top surface of the duct extends forward to form a top baffle; the top baffle is positioned above the air intake channel, and an air outlet of the air intake channel is positioned on an outer wall of the air intake channel; the air outlet is positioned below the top baffle. Dripping water is prevented from flowing into the air intake channel of the duct while the dryer is working, thereby avoiding short circuits or electrical leakage of the internal electrical components and ensuring safety and proper functioning of the dryer.

An electronic equipment enclosure includes a frame structure at least partially enclosed by a plurality of panels defining a compartment in which one or more electronic components are mounted and an exhaust air duct that is adapted to segregate hot air being exhausted from the compartment from cool air entering the compartment, thereby improving thermal management of the enclosure. The exhaust duct includes a lower duct section extending upward from the top panel of the compartment and an upper duct section telescoping upward from an upper end of the lower duct section. Each duct section includes four panels connected together by hinged corner fittings such that the section is collapsible. The upper duct section includes an outwardly flared portion.

A window air conditioner is provided. The window air conditioner has a housing, an indoor air duct shell, an outdoor air duct shell and a fresh air duct shell. The housing has an indoor air inlet and an indoor air outlet communicated by an indoor air duct formed by the indoor air duct shell. The housing also has an outdoor air inlet and an outdoor air outlet communicated by an outdoor air duct. A fresh air opening communicated with the indoor air duct is provided on the back surface of the indoor air duct shell. The outdoor air duct shell forms a high-pressure area of the outdoor air duct and has a vent for an airflow in the high-pressure area of the outdoor air duct to pass. The fresh air duct shell has a fresh air duct communicating the vent with the fresh air opening.

An air vent includes a housing, an air guide surface, an air flow adjusting element, and a vane. The air guide surface at least partially defines an air duct configured to convey a volumetric flow of air through the housing so that the volumetric flow of air exits the air duct in a direction that at least partially defines an air discharge direction perceived outside of the air vent. The air flow adjusting element is moveable to vertically change the perceived air discharge direction, and the vane is movable to horizontally change the perceived air discharge direction. The vane is not visible to a user of the air vent when the air vent is viewed from an air outlet end of the housing.
