なお、この出願の発明に関連する先行技術文献情報としては、次のものがある。
特開２０００−２３２０２２号公報 The prior art document information related to the invention of this application includes the following.
JP 2000-2322022 A

上記した半導体電力変換装置においては、収納部材４から発生する熱は空気を介して筐体１の上部に伝わるため、吸気口２ａは扉２の下部に設け、排気口１ａは筐体１の上部に設けると、冷却効率が良い。トランスやリアクトル等の収納部材４も発熱するため、周辺の空気の流れを大きくすることにより冷却効率を向上することができ、収納部材４の小形化が可能となる。しかしながら、冷却空気は筐体１及び扉２と取付板３との間の狭い空間を通るため、空気の流れが悪くなり、冷却効率が上がらなかった。このため、収納部材４のサイズを大きくして、放熱表面積を増すか、あるいは別途ファンモータを用いて空気を流す方法が用いられたが、大型で高価なものとなった。   In the semiconductor power conversion device described above, the heat generated from the storage member 4 is transmitted to the upper portion of the housing 1 via the air. If it is provided, cooling efficiency is good. Since the storage member 4 such as a transformer or a reactor also generates heat, the cooling efficiency can be improved by increasing the flow of the surrounding air, and the storage member 4 can be downsized. However, since the cooling air passes through a narrow space between the housing 1 and the door 2 and the mounting plate 3, the air flow is deteriorated and the cooling efficiency is not improved. For this reason, a method of increasing the size of the storage member 4 to increase the heat radiating surface area or flowing air using a separate fan motor has been used, but it is large and expensive.

この発明は上記のような課題を解決するために成されたものであり、小形で安価な半導体電力変換装置を得ることを目的とする。   The present invention has been made to solve the above-described problems, and an object thereof is to obtain a small and inexpensive semiconductor power conversion device.

この発明の請求項１に係る半導体電力変換装置は、筐体内に取り付けられた取付板上に収納部材を取り付けた半導体電力変換装置において、取付板を、筐体の下部に設けられ、冷却空気を吸入する吸気口と筐体の上部に設けられ、冷却空気を排出する排気口との間を仕切るように取り付けるとともに、取付板に切り起こし加工により通気口を形成し、かつ通気口の切り起こし部分は冷却空気を収納部材方向に導くように折り曲げられているものである。   A semiconductor power conversion device according to claim 1 of the present invention is a semiconductor power conversion device in which a housing member is mounted on a mounting plate mounted in a housing. Attached so as to partition between the intake port for suction and the exhaust port for exhausting cooling air, and is formed by cutting and raising the mounting plate to form a ventilation port. Is bent so as to guide the cooling air toward the housing member.

以上のようにこの発明の請求項１によれば、筐体の下部に設けられた吸気口と筐体の上部に設けられた排気口との間が取付板により仕切られ、取付板には切り起こし加工により通気口が形成され、この通気口の切り起こし部分は冷却空気を収納部材方向に導くように折り曲げられており、筐体の下部の吸気口から吸入された冷却空気は取付板の通気口をその切り起こし部分により収納部材方向に導かれて通過するので、収納部材の冷却効果が高まり、収納部材を大きくする必要がなく、ファンモータを別途設ける必要もなく、半導体電力変換装置を小形で安価にすることができる。   As described above, according to the first aspect of the present invention, the mounting plate separates the intake port provided in the lower portion of the casing from the exhaust port provided in the upper portion of the casing, and the mounting plate is cut. A vent is formed by raising, and the cut-and-raised part of the vent is bent so as to guide the cooling air toward the housing member, and the cooling air sucked from the lower intake of the housing is vented to the mounting plate. Since the mouth is guided by the cut-and-raised part toward the storage member, the cooling effect of the storage member is enhanced, the storage member does not need to be enlarged, and a fan motor is not required to be separately provided. Can be made inexpensive.

以下、この発明を実施するための最良の形態を図面とともに説明する。図１はこの発明の実施最良形態による半導体電力変換装置の概略縦断側面図、図２は同じく実施最良形態による半導体電力変換装置の扉と右側面板を除去した状態を示し、（ａ）は概略斜視図、（ｂ）は収納部材未取付状態の概略斜視図を示す。図において、６は筐体１内に水平に設けられ、上部にトランスやリアクトル等の収納部材４が取り付けられた取付板であり、取付板６は筐体１内を下部の吸気口２ａ側と上部の排気口１ａ側とに仕切る。取付板６における収納部材４の前後又は左右には切り起こし加工により通気口６ａを形成し、通気口６ａの切り起こし部分６ｂは冷却空気を収納部材４方向に導くように折り曲げられている。   The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 is a schematic longitudinal side view of a semiconductor power conversion device according to the best mode of the present invention, FIG. 2 shows a state in which the door and right side plate of the semiconductor power conversion device according to the best mode are also removed, and FIG. FIG. 4B is a schematic perspective view of the storage member not attached. In the figure, reference numeral 6 denotes a mounting plate that is provided horizontally in the housing 1 and has a storage member 4 such as a transformer or a reactor attached to the upper portion thereof. The mounting plate 6 is disposed on the lower intake port 2a side in the housing 1. It partitions to the upper exhaust port 1a side. A vent 6a is formed by cutting and raising the front and rear or the left and right of the storage member 4 in the mounting plate 6, and the cut and raised portion 6b of the vent 6a is bent so as to guide the cooling air toward the storage member 4.

上記構成において、排気ファン５を駆動すると、冷却風は吸気口２ａより吸入され、矢印に示すように、筐体１内を吸気口２ａ側と排気口１ａ側とに仕切る取付板６の通気口６ａを通過し、通気口６ａの切り起こし部分６ｂに案内されて収納部材４方向に導かれ、排気口１ａから排気される。従って、収納部材４は効果的に冷却され、小形化が可能となり、筐体１も小形化が可能となる。又、別途ファンモータを設ける必要も無く、安価にすることができる。   In the above configuration, when the exhaust fan 5 is driven, the cooling air is sucked from the intake port 2a and, as indicated by the arrow, the ventilation hole of the mounting plate 6 that partitions the inside of the housing 1 into the intake port 2a side and the exhaust port 1a side. It passes through 6a, is guided by the cut-and-raised portion 6b of the vent 6a, is guided toward the storage member 4, and is exhausted from the exhaust port 1a. Therefore, the storage member 4 is effectively cooled and can be downsized, and the housing 1 can also be downsized. Further, there is no need to provide a separate fan motor, and the cost can be reduced.
