WIPO Patent Application WO/2018/220967
Kind Code:
A1
Abstract:
In this invention, an electronic machine such as a liquid crystal display is housed inside a casing, and the interior of the casing is turned into a sealed space. A heat exchanger through which external air passes is installed in a central section of the casing. The external air and air within the casing are made to flow across each other performing heat exchange, thereby dissipating heat, and the flow of the internal air aspirated out of the heat exchanger cools the back surface of the liquid crystal display.
