しかしながら、冷房運転の場合、送風機の回転により筐体背面から前方へ流れる空気は熱交換器により暖められるため、この場合、冷却フィンには暖められた空気が流れることとなる。そこで、冷房運転の場合に、冷却フィンの冷却効率を向上させるためには、未だ改善の余地があった。
本発明は、上述した事情に鑑みてなされたものであり、冷却フィンの冷却効率を向上させることのできる室外機を提供することを目的とする。 However, in the case of cooling operation, the rotation of the blower warms the air flowing forward from the rear surface of the housing by the heat exchanger, so in this case, the heated air flows through the cooling fins. Therefore, in the case of cooling operation, there is still room for improvement in order to improve the cooling efficiency of the cooling fins.
SUMMARY OF THE INVENTION It is an object of the present invention to provide an outdoor unit capable of improving the cooling efficiency of cooling fins.

The outdoor unit is provided with the heat-generating member mounted on the side of the heat-generating member, and cooling fins on the rear surface of the heat-generating member on the heat exchange chamber side of the partition plate, wherein the partition plate is mounted on the cooling fin on the basis of the air flow. An opening communicating between the machine chamber and the heat exchange chamber is provided on the upstream side, the opening and the cooling fins are covered, and the cooling fins extend from the opening to the partition plate. A cover member is provided that forms an air passage leading to the heat exchange chamber, and the side flow flowing through the air passage and the rotation of the blower reach the heat exchange chamber through the outdoor heat exchanger on the downstream side of the air passage. It is characterized by having a rectifying plate that suppresses collision with the main stream.

本発明によれば、整流板を設けることにより、風路を流れる副流が熱交換室に至るとき、副流が主流による負圧により風速、風量が上昇する。そのため、冷却フィンを流れる副流の風速、風量が上昇し、冷却フィンの冷却効率を向上させることができる。 According to the present invention, by providing the rectifying plate, when the side stream flowing through the air passage reaches the heat exchange chamber, the negative pressure due to the main side stream increases the wind speed and the air volume. Therefore, the wind velocity and air volume of the side stream flowing through the cooling fins are increased, and the cooling efficiency of the cooling fins can be improved.

図１は室外機１の正面図である。図２は、前面板３を外した状態における室外機１の正面図である。図３は、天面板５を外した状態における室外機１の平面図である。なお、以下の説明において、上下、前後、左右とは、室外機１を正面から見た場合の上下、前後、左右を示している。 FIG. 1 is a front view of the outdoor unit 1. FIG.

本実施形態の室外機１は、いわゆるサイドフロー式である。 As shown in FIGS. 1 to 3, the outdoor unit 1 includes a unit body 10, a front panel 3 attached to the front surface of the unit body 10, and a top panel 5 attached to the top surface of the unit body 10. In the outdoor unit 1, a heat exchange chamber 30 having a blower 26 and an outdoor heat exchanger 24 provided on the back side and a machine chamber 40 containing a heat generating member 50 are partitioned by a partition plate 70. A heat-generating member 50 is attached to the chamber 40 side, and cooling fins 60 are provided on the rear surface of the heat-generating member 50 on the heat exchange chamber 30 side of the partition plate 70 . The heat exchange chamber 30 is located inside the left side chamber of the unit body 10 . The machine room 40 is located in the right side room of the unit main body 10 .
The outdoor unit 1 of this embodiment is of a so-called side flow type.

図３に示すように、ユニット本体１０は、ユニット本体１０の左側側面（ユニット本体の一方の側面）から背面に沿って上面視略Ｌ字状の室外熱交換器２４を備える。
ユニット本体１０の左側側面に設けられる室外熱交換器２４は、ユニット本体１０の前後方向の長さと略等しく設けられている。ユニット本体１０の背面に設けられる室外熱交換器２４は、ユニット本体１０の左右方向にかけて左側から略４分の３程度の幅を備える。
ユニット本体１０の右後方部（ユニット本体１０の他方の側面の後方部）には、上面視略Ｌ字状の後方カバー７２が設けられている。この後方カバー７２の一端部は、室外熱交換器２４の右端部２５と固定されている。後方カバー７２の他端部は、前面板３に固定されている。
ユニット本体１０の左後方の角部には、室外熱交換器２４の外側にコーナーカバー７９が設けられている。 As shown in FIG. 3 , the unit main body 10 includes an outdoor heat exchanger 24 that is generally L-shaped when viewed from the top along the left side surface (one side surface of the unit main body) along the rear surface of the unit main body 10 .
The outdoor heat exchanger 24 provided on the left side surface of the unit main body 10 is provided so as to have substantially the same length as the unit main body 10 in the front-rear direction. The outdoor heat exchanger 24 provided on the rear surface of the unit body 10 has a width of approximately three-fourths from the left side in the horizontal direction of the unit body 10 .
A rear cover 72 having a substantially L shape when viewed from above is provided on the right rear portion of the unit main body 10 (the rear portion of the other side surface of the unit main body 10). One end of the rear cover 72 is fixed to the right end 25 of the outdoor heat exchanger 24 . The other end of the rear cover 72 is fixed to the front panel 3 .
A corner cover 79 is provided outside the outdoor heat exchanger 24 at the left rear corner of the unit body 10 .

図３に示すように、ユニット本体１０には、内部の中央より右寄りの部分に室内を左右に２分割する仕切板７０が上下方向全体にわたって設けられている。
仕切板７０は、ユニット本体１０の前後方向にわたって設けられている。熱交換室３０は、機械室４０より広いスペースとなっている。
仕切板７０は、前後方向に延びる主板部７１と、主板部７１の後端から斜め後方に折り曲げられ室外熱交換器２４の右端部２５（一端部）に固定される案内部７３と、を備える。仕切板７０は、熱交換室３０と機械室４０とを左右に仕切っている。主板部７１は、室外熱交換器２４の右端部２５より熱交換室３０の側に配置される。
これにより、室外熱交換器２４の右端部２５の近傍から吸込まれる空気は、案内部７３に案内され、熱交換室３０の中央方向に流れる。そのため、機械室４０のスペースを確保しつつ、熱交換室の限られたスペース内における熱交換効率が向上する。 As shown in FIG. 3, the unit main body 10 is provided with a partition plate 70 that divides the room into left and right parts over the entire up-down direction in a portion on the right side of the center of the inside.
The partition plate 70 is provided along the front-rear direction of the unit body 10 . The heat exchange room 30 has a larger space than the machine room 40 .
The partition plate 70 includes a main plate portion 71 extending in the front-rear direction, and a guide portion 73 bent obliquely rearward from the rear end of the main plate portion 71 and fixed to the right end portion 25 (one end portion) of the outdoor heat exchanger 24 . . The partition plate 70 partitions the heat exchange chamber 30 and the machine chamber 40 from side to side. The main plate portion 71 is arranged closer to the heat exchange chamber 30 than the right end portion 25 of the outdoor heat exchanger 24 .
As a result, air sucked from the vicinity of the right end portion 25 of the outdoor heat exchanger 24 is guided by the guide portion 73 and flows toward the center of the heat exchange chamber 30 . Therefore, while securing the space of the machine room 40, the heat exchange efficiency in the limited space of the heat exchange chamber is improved.

図４に示すように、仕切板７０は、機械室４０と熱交換室３０とを連通する開口部３１を備える。図４及び図８に示すように、開口部３１は、冷却フィン６０の取り付けられた主板部７１（仕切板）より前方（室外機の正面方向）に位置している。また、開口部３１は、発熱部材５０より前方（室外機の正面方向）に位置している。また、開口部３１は、高さ方向において冷却フィン６０と重なる位置に備えられる。 As shown in FIG. 4 , the partition plate 70 has an opening 31 that communicates the machine chamber 40 and the heat exchange chamber 30 . As shown in FIGS. 4 and 8, the opening 31 is positioned forward (in the front direction of the outdoor unit) of the main plate portion 71 (partition plate) to which the cooling fins 60 are attached. In addition, the opening 31 is located in front of the heat generating member 50 (in the front direction of the outdoor unit). Also, the openings 31 are provided at positions overlapping the cooling fins 60 in the height direction.

室外機１は、開口部３１及び冷却フィン６０を覆うカバー部材６１を備える。カバー部材６１を備えることにより、室外機１は、仕切板７０の主板部７１との間に、開口部３１から冷却フィン６０を介して熱交換室３０に至る風路Ｓを形成する。
風路Ｓには、機械室４０から開口部３１を介して空気が入り、この空気は、冷却フィン６０を介して風路出口６２から熱交換室３０に至る。この風路Ｓを流れる空気を副流Ａとする。 The outdoor unit 1 includes a cover member 61 that covers the opening 31 and the cooling fins 60 . By providing the cover member 61 , the outdoor unit 1 forms an air passage S from the opening 31 to the heat exchange chamber 30 via the cooling fins 60 between the outdoor unit 1 and the main plate portion 71 of the partition plate 70 .
Air enters the air passage S from the machine room 40 through the opening 31 and reaches the heat exchange chamber 30 from the air passage outlet 62 via the cooling fins 60 . The air flowing through this air passage S is called a side stream A. As shown in FIG.

図４及び図７に示すように、風路Ｓの下流側には、風路Ｓを流れる副流Ａと送風機２６の回転により室外熱交換器２４を介して熱交換室に至る主流Ｂとの衝突を抑制する整流板１００が備えられる。
整流板１００は、主板部７１と案内部７３との折り曲げ部分８５から延びている。整流板１００は、冷却フィン６０の出口部分に対向配置される案内面１０１を備える。この案内面１０１（整流板）は、室外機１の背面に位置する室外熱交換器２４に沿って延びている。整流板１００は、仕切板７０を曲げ加工することにより形成される。
案内面１０１とカバー部材６１との間には、上述した風路出口６２が設けられる。
整流板１００（案内面１０１）の長さは、カバー部材６１に覆われる冷却フィン６０の長さ８９と後述する側部弾性体７５（弾性体）の厚さの合計と略等しく形成されている。
なお、整流板１００（案内面１０１）は、カバー部材６１の一部としてもよい。この場合、カバー部材６１は、冷却フィン６０を覆う第１案内部６５と、第１案内部６５の前方に設けられ前方に向けて仕切板７０の側に斜めに折り曲げられた第２案内部６６と、第１案内部の後方に設けられカバー部材６１の背面（室外機１の背面側）を形成する整流板１００（案内面１０１）と、を備える構成としてもよい。カバー部材６１は、箱形状であり、カバー部材６１の角部は、スポット溶接としてもよい。この場合、カバー部材６１の一部である案内面１０１と第１案内部６５の後端部との間に上述した風路出口６２が形成される。 As shown in FIGS. 4 and 7, on the downstream side of the air path S, there is a substream A flowing through the air path S and a main stream B reaching the heat exchange chamber via the outdoor heat exchanger 24 due to the rotation of the blower 26. A rectifying plate 100 is provided to suppress collisions.
Current plate 100 extends from bent portion 85 between main plate portion 71 and guide portion 73 . The rectifying plate 100 has a guide surface 101 facing the exit portion of the cooling fins 60 . This guide surface 101 (rectifying plate) extends along the outdoor heat exchanger 24 located on the back surface of the outdoor unit 1 . The current plate 100 is formed by bending the partition plate 70 .
Between the guide surface 101 and the cover member 61, the above air passage outlet 62 is provided.
The length of the rectifying plate 100 (guide surface 101) is formed substantially equal to the sum of the length 89 of the cooling fins 60 covered with the cover member 61 and the thickness of the later-described side elastic body 75 (elastic body). .
Note that the current plate 100 (guide surface 101 ) may be part of the cover member 61 . In this case, the cover member 61 includes a first guide portion 65 that covers the cooling fins 60 and a second guide portion 66 that is provided in front of the first guide portion 65 and is bent forward toward the partition plate 70 side. and a rectifying plate 100 (guide surface 101) that is provided behind the first guide portion and forms the back surface of the cover member 61 (the back surface side of the outdoor unit 1). The cover member 61 is box-shaped, and the corners of the cover member 61 may be spot-welded. In this case, the air passage outlet 62 described above is formed between the guide surface 101 which is a part of the cover member 61 and the rear end portion of the first guide portion 65 .

図４及び図７に示すように、副流Ａと主流Ｂとは、逆向きから流れるが、整流板１００を備えることにより、副流Ａと主流Ｂとの衝突が抑制される。
主流Ｂには、室外熱交換器２４を介して熱交換室３０に至り、そのまま室外機１の前面から吹き出される第１の主流Ｂ１と、室外熱交換器２４の右端部２５を介して熱交換室３０に至り、仕切板７０の案内部７３及び整流板１００に案内され熱交換室３０の中央方向に至り、室外機１の前面から吹き出される第２の主流Ｂ２と、が存在している。
整流板１００を備えることにより、副流Ａ及び第２の主流Ｂ２は、ともに整流板１００に沿って流れることとなる。整流板１００に沿って流れるとき、副流Ａ及び第２の主流Ｂ２とは、同じ向きに流れる。第２の主流Ｂ２が整流板１００を超えて、熱交換室３０の中央側に至るとき、第２の主流Ｂ２は、第１の主流Ｂ１と合流する。第１の主流Ｂ１及び第２の主流Ｂ２からなる主流Ｂは、副流Ａより風速が速い。主流Ｂによる負圧で副流Ａが引っ張られ、副流Ａの風速、風量が上昇する。主流Ｂにより、副流Ａの風速を増すことができ、ディフューザー効果が期待できる。副流Ａの風速、風量が上昇するため、冷却フィン６０の冷却効率を向上させることができる。 As shown in FIGS. 4 and 7, the side stream A and the main stream B flow in opposite directions, but the collision between the side stream A and the main stream B is suppressed by providing the current plate 100 .
The main stream B reaches the heat exchange chamber 30 via the outdoor heat exchanger 24 and is blown out from the front surface of the outdoor unit 1 as it is. A second mainstream B2 that reaches the exchange chamber 30, is guided by the guide portion 73 of the partition plate 70 and the straightening plate 100, reaches the central direction of the heat exchange chamber 30, and is blown out from the front surface of the outdoor unit 1. there is
By providing the rectifying plate 100 , both the secondary flow A and the second main flow B2 flow along the rectifying plate 100 . When flowing along the rectifying plate 100, the secondary flow A and the second main flow B2 flow in the same direction. When the second main flow B2 passes over the current plate 100 and reaches the center side of the heat exchange chamber 30, the second main flow B2 joins the first main flow B1. The main flow B, which is composed of the first main flow B1 and the second main flow B2, has a higher wind speed than the side flow A. The side stream A is pulled by the negative pressure of the main stream B, and the wind speed and air volume of the side stream A increase. The main stream B can increase the wind speed of the side stream A, and a diffuser effect can be expected. The cooling efficiency of the cooling fins 60 can be improved because the air velocity and air volume of the secondary flow A increase.

図４、図６及び図８に示すように、カバー部材６１は、冷却フィン６０を覆う第１案内部６５と、第１案内部６５から仕切板７０の側に斜めに折り曲げられた第２案内部６６と、を備える。
図８に示すように、仕切板７０を室外機１の正面方向に伸ばした仮想の延長線Ｅと開口部３１の側壁３１Ａとの交点をＦとする。また、発熱部材５０の機械室４０側、かつ、室外機１の正面側の端部をＧとする。交点Ｆと端部Ｇを水平方向に結んだ仮想線８８は、平面視において、冷却フィン６０の長さ８９と略等しい長さとされている。
これにより、開口部３１から入る副流Ａが、冷却フィン６０に効率よく流れるようになる。 As shown in FIGS. 4, 6 and 8, the cover member 61 includes a first guide portion 65 that covers the cooling fins 60 and a second guide that is obliquely bent from the first guide portion 65 to the partition plate 70 side. a portion 66;
As shown in FIG. 8, let F be an intersection point between an imaginary extension line E obtained by extending the partition plate 70 in the front direction of the outdoor unit 1 and the side wall 31A of the opening 31 . Also, let G be the end of the heat generating member 50 on the side of the machine room 40 and on the front side of the outdoor unit 1 . A virtual line 88 connecting the intersection point F and the end portion G in the horizontal direction has a length substantially equal to the length 89 of the cooling fin 60 in plan view.
As a result, the secondary flow A entering from the openings 31 efficiently flows to the cooling fins 60 .

また、第２案内部６６を、第１案内部６５から仕切板７０の側に斜めに折り曲げている。風路Ｓの幅Ｗが、仮想線８８の長さと近くなるように、第２案内部６６は斜めに折り曲げられる。
これにより、開口部３１の入口の面積を狭めることもせず、広げることもせず、近く保ことができ、開口部３１から入る副流Ａが、第２案内部６６に沿って流れるときに、乱流となることが抑制される。 Also, the second guide portion 66 is obliquely bent from the first guide portion 65 toward the partition plate 70 side. The second guide portion 66 is obliquely bent so that the width W of the air passage S is close to the length of the imaginary line 88 .
As a result, the area of the inlet of the opening 31 can be kept close without being narrowed or widened, and the side flow A entering from the opening 31 can be disturbed when flowing along the second guide portion 66. flow is suppressed.

風路出口６２の幅を、仮想線８８の長さと略等しくしてもよい。これにより、風路出口６２から熱交換室３０に至る副流Ａが乱流となることが抑制される。 The width of the air passage outlet 62 may be approximately equal to the length of the imaginary line 88 . As a result, the secondary flow A from the air passage outlet 62 to the heat exchange chamber 30 is suppressed from becoming turbulent.

開口部３１に位置する風路Ｓの入口部分となる仮想線８８の長さと、風路Ｓの幅Ｗと、風路出口６２の幅とは、略等しく形成してもよい。これにより、風路出口６２から熱交換室３０に至る副流Ａが乱流となることが抑制される。冷却フィン６０の冷却効率を向上できる。 The length of the imaginary line 88 serving as the entrance portion of the air passage S located in the opening 31, the width W of the air passage S, and the width of the air passage outlet 62 may be formed substantially equal. As a result, the secondary flow A from the air passage outlet 62 to the heat exchange chamber 30 is suppressed from becoming turbulent. The cooling efficiency of the cooling fins 60 can be improved.

本実施の形態に係る冷却フィン６０は、仕切板７０の主板部７１から熱交換室３０の側に水平方向に立ち上がる形状を備える。冷却フィン６０は、先端部６７（熱交換室側）が熱交換室３０の側に向けて開放している。そこで、この開放した先端部６７から副流Ａが漏れることにより冷却フィン６０の冷却効率が低下することを抑制するために、発熱体５３の裏側の部分まで、側部弾性体７５（弾性体）を特に延ばしている。
弾性体は、冷却フィンの６０の前端部（副流Ａの流れの上流側の端部）から、冷却フィン６０の開放された部分であって、かつ、仕切板７０を介した発熱体５３の裏側の部分まで、延びていればよい。 The cooling fins 60 according to the present embodiment have a shape that rises horizontally from the main plate portion 71 of the partition plate 70 toward the heat exchange chamber 30 side. The cooling fins 60 are opened toward the heat exchange chamber 30 at the tip portions 67 (on the heat exchange chamber side). Therefore, in order to suppress the deterioration of the cooling efficiency of the cooling fins 60 due to the leakage of the secondary flow A from the open tip portion 67, the side elastic body 75 (elastic body) is extended to the back side of the heating element 53. is especially extended.
