POWER CONVERSION DEVICE

PROBLEM TO BE SOLVED: To provide a power conversion device which directly fits a housing of a power conditioner to an outer wall of a house, and can prevent infiltration of rainwater into the housing and form an air flow for effectively exercising a heat radiation action on heating portions of various kinds of electrical components equipped in the housing and perform cleaning and exchange of a filter provided in an air intake port by a person who is not qualified as an electrician.SOLUTION: Right and left air flow-in ports 12 are provided at an intermediate portion between the left and right walls of a main body 3 or at the lower portion of the main body 3, and an air exhaust port 13 is provided in the lower wall. An air introducing port 15 intercommunicating with the air flow-in ports is formed on the lower side, and an air intake cover 14 having a dust-proof filter 15F is provided at the air introducing port so as to be freely detachably fitted to the outer surfaces of the right and left walls of the main body while covering each of the right and left air flow-in ports. The operation of heat radiating fans 10 and 11 forms an air stream in which the outside air flowing in from the right and left air flow-in ports is exhausted from the air exhaust port to the outside of the housing while promoting heat dissipation of electric parts.SELECTED DRAWING: Figure 6 【課題】パワーコンディショナの筐体を家屋の外壁に直接取り付ける電力変換装置として、筺体内部への雨水の侵入を防止し、且つ、その筺体内部に備えた各種電気部品の発熱部分の放熱作用を効果的に発揮するための空気の流れの形成と共に、電気工事士の資格の無い者による空気取り入れ口に設けるフィルタの清掃、交換が可能な電力変換装置を提供する。【解決手段】本体３の左右壁の中間部または下部に左右の空気流入口１２、下壁に空気排出口１３を備え、空気流入口へ連通する空気導入口１５を下側に形成し、空気導入口には防麈フィルタ１５Ｆを有する空気取り入れカバー１４が、左右の空気流入口をそれぞれ覆う状態で本体の左右壁の外面に着脱自在に取り付けられ、放熱用ファン１０、１１の運転によって、左右の空気流入口から流入した外気が電気部品の放熱を促進しつつ空気排出口から筐体外へ排気される空気の流れを形成する。【選択図】図６
