摘要:
An antenna for ultra-wide band communication is disclosed. The antenna includes a substrate (108), a patch (101) formed on one side of the substrate so as to be smaller than the substrate, and being excited when an electric current is supplied through a feeder line (103), so as to radiate energy, and a ground area (107) formed by removing a portion of another side of the substrate so as to obtain a wide band characteristic.
摘要:
A humidifier is disclosed which includes a desiccant wheel (54), and a heat exchanger adapted to heat-exchange air dehumidified in an absorption chamber (60) with air introduced into a regeneration chamber (70). The heat of the air dehumidified in the absorption chamber (60) can be used to increase the temperature of ambient air introduced into the regeneration chamber (70), thereby reducing the load of a heater (56) to heat the temperature of the ambient air introduced into the regeneration chamber (70), and thus, achieving a reduction in the power consumption of the heater (56).
摘要:
An air conditioner including a housing and a fan within the housing is provided. The fan may be configured to draw air into the housing and direct air radially outward. A heat exchanger may be configured to exchange heat with the air drawn into the housing. Also, at least one airflow guide may be configured to extend into a flow path of the air so that the flow of air is guided through the heat exchanger along a surface of the airflow guide.
