Description

第2の仕切板7Aは、たとえば金属製であり、第1および第2の風路9,9’と配置空間B1とを仕切るものである。第2の仕切板7Aは、ベース部材1と同程度のF方向寸法を有し、ベース部材1および第1の仕切板6に対して垂直に配置される。すなわち、第2の仕切板7Aは、第1および第2の風路9,9’の垂直壁をなす。この第2の仕切板7Aの下側部分には、電気部品31,32が貫通して嵌合可能な開口71,72が設けられている。図に示すように、第2の仕切板7Aの風路9’の内側となる片面上側部分には、ヒートシンク5が配置される。さらに、第2の仕切板7Aには、ヒートシンク5の一部を配置空間B1に対して露出させるための開口73が設けられている。 The second partition plate 7A is made of, for example, metal, and partitions the first and second air paths 9, 9 ′ from the arrangement space B1. The second partition plate 7 </ b> A has the same F-direction dimension as the base member 1, and is disposed perpendicular to the base member 1 and the first partition plate 6. That is, the second partition plate 7A forms a vertical wall of the first and second air passages 9, 9 ′. The lower part of the second partition plate 7A is provided with openings 71 and 72 through which the electrical components 31 and 32 can be fitted. As shown in FIG. 3 , the heat sink 5 is disposed on the upper side of one side that is the inside of the air passage 9 ′ of the second partition plate 7 </ b> A. Further, the second partition plate 7A is provided with an opening 73 for exposing a part of the heat sink 5 to the arrangement space B1.

電気部品31は、たとえばトランスであり、図8および図9に示すように、本体部31Aと、5本の端子部31Bとを有する。本体部31Aは、図9に示すように、コア部311、一次巻線部312、二次巻線部313、支持部材314、および、樹脂カバー315を備えている。コア部311は、たとえばコの字状あるいはEの字状の金属芯である。一次および二次巻線部312,313はそれぞれコイルを形成するようにコア部311に巻き回されている。本実施形態では二次巻線部313を挟むように一次巻線部312が配置されている。支持部材314は、板状の底部314Aと蓋部314Bとの間にコア部311を挟んで固定している。底部314A、蓋部314B、およびコア部311は複数のネジ314aによって固定されている。樹脂カバー315は、コア部311、一次巻線部312、二次巻線部313、および、支持部材314の底部314Aを覆うように、たとえばウレタン樹脂、エポキシ樹脂、またはシリコーン樹脂によって形成されている。樹脂カバー315は、一端部315aが第1の風路9に対して臨み、他端部315bが配置空間B1に臨むように後述する開口71に嵌合させられている。樹脂カバー315の一端側315aには、複数の放熱フィン316が形成されている。5本の端子部31Bは、樹脂カバー315の他端315bから突出するように設けられている。各端子部31Bは、それぞれ、一次巻線部312の両端、二次巻線部313の両端および二次巻線部313の適所に接続されている。 The electrical component 31 is a transformer, for example, and has a main body 31A and five terminal portions 31B as shown in FIGS. As shown in FIG. 9, the main body portion 31 </ b> A includes a core portion 311, a primary winding portion 312, a secondary winding portion 313, a support member 314, and a resin cover 315. The core part 311 is, for example, a U-shaped or E-shaped metal core. The primary and secondary winding portions 312 and 313 are wound around the core portion 311 so as to form coils. In this embodiment, the primary winding part 312 is arrange | positioned so that the secondary winding part 313 may be pinched | interposed. The support member 314 is fixed by sandwiching the core portion 311 between the plate-like bottom portion 314A and the lid portion 314B. The bottom portion 314A, the lid portion 314B, and the core portion 311 are fixed by a plurality of screws 314a. The resin cover 315 is formed of, for example, urethane resin, epoxy resin, or silicone resin so as to cover the core portion 311, the primary winding portion 312, the secondary winding portion 313, and the bottom portion 314A of the support member 314. . The resin cover 315 is fitted into an opening 71 described later so that one end 315a faces the first air passage 9 and the other end 315b faces the arrangement space B1. A plurality of heat radiating fins 316 are formed on one end side 315 a of the resin cover 315. The five terminal portions 31B are provided so as to protrude from the other end portion 315b of the resin cover 315. Each terminal portion 31B is connected to both ends of the primary winding portion 312, both ends of the secondary winding portion 313, and appropriate positions of the secondary winding portion 313, respectively.

第1および第2のファン8,8’が動作すると、吸入口80,80’周辺の空気が第1および第2のファン8,8’に取り込まれ、その空気が第1および第2の風路9,9’の長手方向に対して交差する方向に吐出口81,81’から風路9,9’内に送り出される。それに伴い配置空間B2には、吸気孔部20から外部の空気が流入する。 When the first and second fans 8 and 8 ′ are operated, the air around the suction ports 80 and 80 ′ is taken into the first and second fans 8 and 8 ′, and the air flows into the first and second winds. It is sent out into the air passages 9 and 9 'from the discharge ports 81 and 81' in a direction intersecting with the longitudinal direction of the passages 9 and 9 '. Accordingly, outside air flows from the intake hole 20 into the arrangement space B2.
