Abstract: Disclosed is a wireless charger for a mobile terminal in a vehicle, the wireless charger including: a tray on which the mobile terminal is placed and which has one or more holes; a coil part configured to wirelessly provide electrical energy to the mobile terminal; a driving part configured to drive the coil part; a case which accommodates the coil part and the driving part and in which an air flow path is formed; and a fan module configured to discharge air toward the mobile terminal through the holes or suction ambient air of the mobile terminal.

Abstract: The present invention relates to a display apparatus. According to an embodiment of the present invention, the display apparatus includes a case, a display inside the case, and a heat exchanger disposed on a rear surface of the case to perform heat exchange between an outside and an inside of the case, wherein a first space and a second space separated from each other are formed on a front surface and a rear surface of the display, respectively, and heat exchange is performed between the first space and the second space, wherein heat exchange with the second space and the outside is performed through the heat exchanger. Thereby, the temperature inside the display apparatus that is installable outside may be effectively cooled.
