Description

本発明は、電気機器屋外用ユニットに関するものである。   The present invention relates to an electric equipment outdoor unit.

従来、屋外にて各種電気機器を収納する電気機器屋外用ユニットにおいては、放熱、防水を考慮する必要があることから、屋外から取り込んだ外気を用いて電気機器を冷却する吸排気構造が用いられている（特許文献１〜４等参照）。
図８は、従来の電気機器屋外用ユニットの一例を示す縦断面図であり、この電気機器屋外用ユニット１は、電気機器（図示略）を収納するユニット本体２の側壁部３に冷却用外気を取り込むための開口部４が形成され、これらの開口部４各々には、側壁部３から斜め下方に延びて開口部４を覆うとともに下向きの開口５を有するルーバー６が設けられている。
この電気機器屋外用ユニット１では、これらのルーバー６により外から雨水が浸入し難くなっている。 Conventionally, in an outdoor unit for electrical equipment that houses various electrical equipment outdoors, it is necessary to consider heat dissipation and waterproofing, so an intake / exhaust structure that cools electrical equipment using outside air taken in from the outdoors has been used. (See Patent Documents 1 to 4).
