Abstract:
(EN) 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.
(FR) Dans la présente invention, une machine électronique telle qu'un affichage à cristaux liquides est installée à l'intérieur d'un boîtier, et l'intérieur du boîtier est transformé en un espace hermétiquement fermé. Un échangeur de chaleur à travers lequel passe l'air extérieur est installé dans une section centrale du boîtier. L'air extérieur et l'air à l'intérieur du boîtier sont amenés à circuler l'un à travers l'autre en effectuant un échange de chaleur, ce qui permet de dissiper la chaleur, et le flux de l'air interne aspiré hors de l'échangeur de chaleur refroidit la surface arrière de l'affichage à cristaux liquides.
(JA) 液晶ディスプレイなどの電子機器を筺体内に収めて、その筺体の内部を密閉空間にした上で、筺体中央部に外気を通過させる熱交換器を設け、外気と筺体内の空気を直交して流して熱交換を行うことで放熱し、熱交換器から内部空気を吸い出したファンの流れによって液晶ディスプレイの背面を冷却する。
