A circular hole 54 is provided below the projecting portion 48 for passing the wiring connected to the control board 42 and the electrical component 43.

箱形の突出部４８は、収納部４５に対し、ヒートシンク４４側に寄って連接され、互いの内部が上記開口４９を介して連通しており、しかも、空気の導入口（スリット）４６および排出口（スリット）４７を有している。突出部４８は、収納部４５に相似で、相似比三分の一程度の大きさであり、その容積は収納部４５よりもかなり小さく、その内側は中空であり、該中空部は送風経路となる。   The box-shaped projecting portion 48 is connected to the housing portion 45 toward the heat sink 44 side, and the inside thereof is in communication via the opening 49. In addition, the air inlet (slit) 46 and the exhaust 46 are connected to each other. An outlet (slit) 47 is provided. The projecting portion 48 is similar to the housing portion 45 and has a size of about one third of the similarity ratio, its volume is considerably smaller than that of the housing portion 45, and the inside thereof is hollow, and the hollow portion is connected to the air flow path. Become.

この電装箱４１は、図３に示すように、取付けブラケット５１を有し、上記突出部４８をユニット本体５の側板１１Ｂに設けた開口５２内に挿入した状態で、ユニット本体５の外側面に対し、ブラケット５１を介して固定されている。
側板１１Ｂの開口５２内に挿入された突出部４８は、図２に示すように、一方の送風ファン２９Ｂによる送風経路５５内に突出し、この状態で、空気の導入口（スリット）４６を図中の下に向け、排出口（スリット）４７を、送風ファン２９Ｂの吸込軸方向に向けて配置されている。導入口４６は、突出部４８の側板４８Ａに設けられている。また、排出口４７は、側板４８Ａに隣接するとともに、上記送風ファン２９Ｂの吸込口６０に対向する側板４８Ｂの導入口４６から遠い位置に設けられている。
この構成では、導入口４６から入った空気が、制御基板４２の裏面を冷却し、導入口４６から遠い、側板４８Ｂに設けた排出口４７から、送風ファン２９Ｂの吸込軸方向に吹き出され、当該送風ファン２９Ｂに吸引される。 As shown in FIG. 3, the electrical box 41 has a mounting bracket 51, and the projection 48 is inserted into the opening 52 provided in the side plate 11 </ b> B of the unit body 5, and is attached to the outer surface of the unit body 5. On the other hand, it is fixed via a bracket 51.
As shown in FIG. 2, the protruding portion 48 inserted into the opening 52 of the side plate 11B protrudes into the blowing path 55 by one blowing fan 29B, and in this state, the air inlet (slit) 46 is shown in the drawing. The discharge port (slit) 47 is arranged toward the suction shaft direction of the blower fan 29B. The introduction port 46 is provided in the side plate 48 </ b> A of the protrusion 48. The discharge port 47 is provided at a position adjacent to the side plate 48A and far from the introduction port 46 of the side plate 48B facing the suction port 60 of the blower fan 29B.
In this configuration, the air that has entered from the introduction port 46 cools the back surface of the control board 42, and is blown out from the discharge port 47 provided on the side plate 48 </ b> B far from the introduction port 46 in the direction of the suction axis of the blower fan 29 </ b> B. The air is sucked into the blower fan 29B.

次に動作を説明する。
本実施の形態では、送風ファン２９Ａ、２９Ｂが駆動されると、ユニット本体５への空気の吸込口３０からユニット本体５に空気が吸込まれ、この空気が、室内熱交換器２１で熱交換されて、ユニット本体５の吹出口４０から吹き出され、この吹出口４０にダクト接続された室内側の吹出口を通じて、室内に調和空気が吹き出される。 Next, the operation will be described.
In the present embodiment, when the blower fans 29 </ b> A and 29 </ b> B are driven, air is sucked into the unit body 5 from the air suction port 30 to the unit body 5, and this air is heat-exchanged by the indoor heat exchanger 21. Then, the conditioned air is blown out into the room through the air outlet on the indoor side which is blown out from the air outlet 40 of the unit main body 5 and is duct-connected to the air outlet 40.

この過程において、送風ファン２９Ｂの吸込経路には、収納部４５から突出した突出部４８が位置しているため、吸込まれた空気の一部は、突出部４８に設けた導入口４６から、突出部４８の内部に入り、突出部４８に入った空気は、スリット４６を通過する際に、剥離して乱流となる。
収納部４５内には制御基板４２の裏面が露出し、空気は基板裏を通過する際に、強制対流で熱交換し、熱交換して高温となった空気は、その後、突出部４８の側板４８Ｂのスリット４７から突出部４８の外に出て、吸い込み圧力によって送風ファン２９Ｂの吸込口６０の外周部へと導かれる。 In this process, since the protruding portion 48 protruding from the storage portion 45 is located in the suction path of the blower fan 29B, a part of the sucked air protrudes from the inlet 46 provided in the protruding portion 48. The air that enters the portion 48 and enters the protruding portion 48 is separated and becomes turbulent when passing through the slit 46.
The back surface of the control board 42 is exposed in the storage section 45, and the air exchanges heat by forced convection when passing through the back of the board. From the slit 47 of 48B, it comes out of the protrusion part 48, and is guide | induced to the outer peripheral part of the suction inlet 60 of the ventilation fan 29B by suction pressure.

本構成では、導入口４６から入った空気が、導入口４６から遠い排出口４７から吹き出されるため、この空気は突出部４８の内部を広く循環し、制御基板４２の裏面を効果的に冷却する。従って、本実施形態によれば、ユニット本体５が設置された天井裏空間よりも温度の低い室内空気によって、基板裏面が常に強制対流にさらされるため、従来のものに比べて電装箱４１をより簡単に冷却できる。電装箱４１内部を通過する空気量が増大し、電装箱４１の温度上昇を抑制することができる。なお、突出部４８にスリットを設けない場合の電装箱４１の温度と比較すると、部位によっては最大約４０℃の温度差ができるという実験データがある。   In this configuration, since the air that has entered from the inlet 46 is blown out from the outlet 47 that is far from the inlet 46, this air circulates widely within the protrusion 48 and effectively cools the back surface of the control board 42. To do. Therefore, according to the present embodiment, the back surface of the substrate is always exposed to forced convection by indoor air having a temperature lower than that of the ceiling space where the unit body 5 is installed. Easy to cool. The amount of air passing through the inside of the electrical box 41 is increased, and the temperature rise of the electrical box 41 can be suppressed. In addition, there is experimental data that a temperature difference of about 40 ° C. at the maximum can be made depending on the part as compared with the temperature of the electrical equipment box 41 in the case where no slit is provided in the protrusion 48.

以上、一実施形態に基づいて、本発明を説明したが、本発明は、これに限定されるものではない。例えば、本実施形態では、突出部本体が直方体であり、開口部として縦に刻まれたスリットを挙げたが、突出部本体を円柱形に形成し、またはスリットをメッシュ状の構造などとすることもできる。   As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this. For example, in the present embodiment, the protrusion main body is a rectangular parallelepiped, and a slit that is vertically cut as an opening is cited. However, the protrusion main body is formed in a cylindrical shape, or the slit has a mesh-like structure or the like. You can also.
