＜第１実施形態＞
本発明の例示的な一実施形態の冷却装置について説明する。図１は本発明の例示的な第１実施形態に係る冷却装置の平面図である。図２は、本発明の例示的な第１実施形態に係る冷却装置の正面図である。図３は、本発明の例示的な第１実施形態に係る冷却ユニットの斜視図である。 <First Embodiment>
A cooling apparatus according to an exemplary embodiment of the present invention will now be described. 1 is a plan view of a cooling device according to a first exemplary embodiment of the present invention; FIG. 2 is a front view of a cooling device according to a first exemplary embodiment of the present invention; FIG. 3 is a perspective view of a cooling unit according to a first exemplary embodiment of the present invention; FIG.

冷却装置１は、複数の冷却ユニット１１と遮閉部材１２とカバー部材１５とを有する。 The cooling device 1 has a plurality of cooling units 11 , shielding members 12 and cover members 15 .

遮閉部材１２の少なくとも一部は、隣り合う冷却ユニット１１の間に配置される。複数の冷却ユニット１１を配置した際に、冷却ユニット１１の間に冷却風が流れ込むため、ラジエータ２１の冷却効率が低下する。隣り合う冷却ユニット１１の間に遮閉部材１２を配置することで、隣り合う冷却ユニット１１の間への冷却風の流れを阻害し、冷却風をラジエータ２１側へ流し込むことで、ラジエータ２１の冷却効率が向上する。 At least part of the blocking member 12 is arranged between adjacent cooling units 11 . When a plurality of cooling units 11 are arranged, the cooling efficiency of the radiator 21 is lowered because the cooling air flows between the cooling units 11 . By arranging the blocking member 12 between the adjacent cooling units 11, the flow of the cooling air between the adjacent cooling units 11 is obstructed, and the cooling air is flowed to the radiator 21 side, thereby cooling the radiator 21. Improve efficiency.

冷却ユニット１１は、コールドプレート２０、およびラジエータ２１を有する。ラジエータ２１は、コールドプレートの２０上側に配置される。コールドプレート２０の上面とラジエータ２１の下面とが接触する。 The cooling unit 11 has a cold plate 20 and a radiator 21 . A radiator 21 is placed 20 above the cold plate. The top surface of the cold plate 20 and the bottom surface of the radiator 21 are in contact with each other.

＜コールドプレート＞
コールドプレート２０は、銅又はアルミニウム等の熱伝導性の高い金属からなり、上面視において水平方向に拡がる矩形の板状である。なお、本実施形態のコールドプレート２０は上面視において四角形であるがこの限りではなく、例えば、上面視において複数の角を有する多角形、または円形であってもよい。コールドプレート２０の下面には発熱部品３０が配置される。 <Cold plate>
The cold plate 20 is made of metal with high thermal conductivity such as copper or aluminum, and has a rectangular plate shape extending horizontally when viewed from above. Although the cold plate 20 of this embodiment has a quadrangular shape when viewed from above, it is not limited to this, and may have, for example, a polygonal shape having a plurality of corners or a circular shape when viewed from above. A heat-generating component 30 is arranged on the lower surface of the cold plate 20 .

コールドプレート２０は、内部に冷媒が流通する第１冷媒流路を有する（不図示）。第１冷媒流路は、コールドプレート２０内の空間である。第１冷媒流路の内部には平行に複数並んで配置されるブレード（不図示）が設けられる。また、第１冷媒流路には流入口（不図示）および流出口（不図示）が設けられる。流入口を介して第１冷媒流路に流入した冷媒は流出口を介して第１冷媒流路から放出する。 The cold plate 20 has a first coolant channel (not shown) through which coolant flows. The first coolant channel is the space within the cold plate 20 . A plurality of blades (not shown) arranged in parallel are provided inside the first coolant channel. In addition, an inlet (not shown) and an outlet (not shown) are provided in the first coolant channel. The coolant that has flowed into the first coolant channel through the inlet is discharged from the first coolant channel through the outlet.

本実施形態における冷媒は液体であり、例えば、エチレングリコール水溶液またはプロピレングリコール水溶液のような不凍液や純水等が使用される。 The coolant in this embodiment is a liquid, and for example, an antifreeze liquid such as an ethylene glycol aqueous solution or a propylene glycol aqueous solution, pure water, or the like is used.

＜ラジエータ＞
ラジエータ２１は、コールドプレート２０の水平方向に垂直な第１方向の上側に配置される。ラジエータ２１は、冷却用の複数のフィン２２およびパイプ２３を有する。フィン２２は平板上に形成され、コールドプレート２０の上面から起立し、第１方向と垂直な第２方向に延びる。フィン２２は、コールドプレート２０の上面で平行に延び、等間隔に複数配置される。ラジエータ２１に設けられたフィン２２は互いに平行に配置されている。さらに、複数の冷却装置１において、各々のフィン２２は、同じ第２方向に延びる。 <Radiator>
The radiator 21 is arranged above the cold plate 20 in a first direction perpendicular to the horizontal direction. Radiator 21 has a plurality of fins 22 and pipes 23 for cooling. The fins 22 are formed on a flat plate, stand up from the upper surface of the cold plate 20, and extend in a second direction perpendicular to the first direction. The fins 22 extend in parallel on the upper surface of the cold plate 20 and are arranged at regular intervals. The fins 22 provided on the radiator 21 are arranged parallel to each other. Furthermore, in a plurality of cooling devices 1, each fin 22 extends in the same second direction.

フィン２２の下端はコールドプレート２０の上面と接する。これにより、コールドプレート２０からフィン２２への熱伝導性が向上する。なお、フィン２２とコールドプレート２０とは別の部材であってもよく、同一の部材であってもよい。本実施形態において、フィン２２はコールドプレート２０とは別部材である。フィンの下端は、例えば、コールドプレート２０上面に溶接によって接合される。 The bottom ends of the fins 22 contact the top surface of the cold plate 20 . This improves thermal conductivity from the cold plate 20 to the fins 22 . Note that the fins 22 and the cold plate 20 may be separate members or may be the same member. In this embodiment, the fins 22 are separate members from the cold plate 20 . The lower ends of the fins are joined to the upper surface of the cold plate 20 by welding, for example.

フィン２２がコールドプレート２０と同一の部材である場合、例えば、フィン２２はコールドプレート２０を切削加工して形成される。なお、フィン２２とコールドプレート２０とが別部材の場合、上述のコールドプレート２０と同様に、フィン２２は銅又はアルミニウム等の熱伝導性の高い金属であることが好ましい。フィン２２が、コールドプレート２０と同様な熱伝導性の高い金属で形成されることで、コールドプレート２０からの熱を効率よくフィン２２へ伝達することができる。 If the fins 22 are the same member as the cold plate 20, the fins 22 are formed by cutting the cold plate 20, for example. If the fins 22 and the cold plate 20 are separate members, the fins 22 are preferably made of a highly thermally conductive metal such as copper or aluminum, like the cold plate 20 described above. By forming the fins 22 from the same highly thermally conductive metal as the cold plate 20 , the heat from the cold plate 20 can be efficiently transferred to the fins 22 .

パイプ２３は、内部が中空であって冷媒が通る第２の冷媒流路を形成する。第２冷媒流路の一方側端部は、第１冷媒流路と連通する。後述するが、第２冷媒流路は、例えば、タンクやポンプを介して第１冷媒流路と連通してもよい。 The pipe 23 is hollow inside and forms a second coolant channel through which the coolant passes. One end of the second coolant channel communicates with the first coolant channel. As will be described later, the second coolant channel may communicate with the first coolant channel via, for example, a tank or a pump.

パイプ２３は、第３方向に直線状に延びる。パイプ２３は、複数のフィン２２に設けられた貫通孔に挿通されて溶接により複数のフィン２２と固定される。このとき、パイプ２３の延びる方向とフィン２２の延びる方向とが直交する。つまり、本実施形態において、複数のフィン２２は第２方向に延び、パイプ２３は第３方向に延びる。 The pipe 23 extends linearly in the third direction. The pipe 23 is inserted through the through-holes provided in the plurality of fins 22 and fixed to the plurality of fins 22 by welding. At this time, the extending direction of the pipe 23 and the extending direction of the fins 22 are perpendicular to each other. That is, in this embodiment, the fins 22 extend in the second direction and the pipes 23 extend in the third direction.

本実施形態では、各冷却ユニット１１は同様の構成であり、同様の大きさである。各冷却ユニット１１は、第３方向に平行して配置される。各冷却ユニット１１は、第２方向の端部が面一である。複数の冷却ユニット１１のうち、隣り合う冷却ユニット１１は第３方向に隙間を介して配置される。また、各冷却ユニット１１はそれぞれ異なる大きさであってもよい。 In this embodiment, each cooling unit 11 has a similar configuration and a similar size. Each cooling unit 11 is arranged in parallel in the third direction. Each cooling unit 11 has flush ends in the second direction. Adjacent cooling units 11 among the plurality of cooling units 11 are arranged with a gap in the third direction. Also, each cooling unit 11 may have a different size.

＜タンク＞
冷却ユニット１１は、第１タンク４１と第２タンク４２とをさらに有する。パイプ２３の一端は第１タンク４１と連結され、パイプ２３の他端は第２タンク４２と連結される。第１タンク４１及び第２タンク４２はパイプ２３の延びる方向に対向して配置される。冷媒は、パイプ２３を介して第１タンク４１から第２タンク４２へ直線状に円滑に流通する。 <Tank>
The cooling unit 11 further has a first tank 41 and a second tank 42 . One end of the pipe 23 is connected to the first tank 41 and the other end of the pipe 23 is connected to the second tank 42 . The first tank 41 and the second tank 42 are arranged facing each other in the direction in which the pipe 23 extends. The coolant smoothly flows linearly from the first tank 41 to the second tank 42 through the pipe 23 .

第１タンク４１及び第２タンク４２は、フィン２２の配列方向に対して平行に配置されており、第１タンク４１と第２タンク４２との間に複数のフィン２２を所定の間隔でより多く配置することができる。これにより、フィン２２全体の表面積を大きくしてラジエータ２１の冷却性能を向上することができる。また、パイプ２３と第１タンク４１及び第２タンク４２とを容易に接続することができる。 The first tank 41 and the second tank 42 are arranged parallel to the direction in which the fins 22 are arranged. can be placed. Thereby, the surface area of the fins 22 as a whole can be increased, and the cooling performance of the radiator 21 can be improved. Also, the pipe 23 can be easily connected to the first tank 41 and the second tank 42 .

パイプ２３は、第１タンク４１及び第２タンク４２の側面を貫通して第１タンク４１及び第２タンク４２に直接連結される。これにより、冷却装置１の部品点数を削減することができる。 The pipe 23 penetrates the sides of the first tank 41 and the second tank 42 and is directly connected to the first tank 41 and the second tank 42 . Thereby, the number of parts of the cooling device 1 can be reduced.

第１タンク４１および第２タンク４２は直方体である。第２タンクは後述するポンプ２４と接続する孔部（不図示）が設けられる。 The first tank 41 and the second tank 42 are rectangular parallelepipeds. The second tank is provided with a hole (not shown) that connects with a pump 24, which will be described later.

第１タンク４１及び第２タンク４２を設けることで、冷却ユニット１１内に循環させる冷媒の量を増やすことができる。したがって、冷却ユニット１１の冷却効率が向上する。 By providing the first tank 41 and the second tank 42, the amount of refrigerant circulated in the cooling unit 11 can be increased. Therefore, the cooling efficiency of the cooling unit 11 is improved.

＜ポンプ＞
冷却ユニット１１は、ポンプ２４をさらに有する。本実施形態における、ポンプ２４は遠心型ポンプであり、直方体形状の筐体の内部に冷媒の流路である、ポンプ流路を有する（不図示）。ポンプ流路には、羽根車（不図示）が配置される。筐体は吸込口（不図示）と吐出口（不図示）とを有する。 <Pump>
The cooling unit 11 further has a pump 24 . In the present embodiment, the pump 24 is a centrifugal pump, and has a pump channel (not shown), which is a coolant channel, inside a rectangular parallelepiped housing. An impeller (not shown) is arranged in the pump channel. The housing has an inlet (not shown) and an outlet (not shown).

ポンプ２４の吸込口とラジエータ２１と第２流路とは直接的、または、間接的に接続される。吐出口は吸込口と連通する。本実施形態では、ポンプ２４の吸込口とラジエータ２１とは第２タンク４２を介して接続される。 The suction port of the pump 24, the radiator 21 and the second flow path are directly or indirectly connected. The outlet communicates with the inlet. In this embodiment, the suction port of the pump 24 and the radiator 21 are connected via the second tank 42 .

ポンプ２４の羽根車は第１方向に延びる中心軸を中心に回転可能に支持され、モータ（不図示）の回転軸と連結される。モータの駆動により羽根車が回転し、吸込口から流入した冷媒が吐出口から吐出される。ポンプ２４は吸込口を介してパイプ２３の延びる方向に冷媒を吸き込む。 The impeller of the pump 24 is rotatably supported around a central axis extending in the first direction and connected to the rotating shaft of a motor (not shown). The impeller is driven by the motor, and the refrigerant that has flowed in from the suction port is discharged from the discharge port. The pump 24 sucks the refrigerant through the suction port in the direction in which the pipe 23 extends.

本実施形態では、ポンプ２４はラジエータ２１に隣接して配置される。 In this embodiment, the pump 24 is arranged adjacent to the radiator 21 .

コールドプレート２０には、側面が切り欠かれた切欠部２０ａが形成される。ポンプ２４の少なくとも一部は、切欠部２０ａに配置されてラジエータ２１と第２方向に対向して配置される。詳細には、ポンプはラジエータ２１の側面に配置される。これにより、冷却ユニット１１全体をより小型化することができる。また、冷却ユニット１１全体の大型化を抑えながら、限られた冷却装置１のスペースにおいてポンプ２４を大型化及び高出力化することができる。 The cold plate 20 is formed with a notch portion 20a having a notched side surface. At least part of the pump 24 is arranged in the notch 20a to face the radiator 21 in the second direction. Specifically, the pump is arranged on the side of the radiator 21 . As a result, the entire cooling unit 11 can be made more compact. In addition, it is possible to increase the size and output of the pump 24 in the limited space of the cooling device 1 while suppressing an increase in the overall size of the cooling unit 11 .

（冷却ユニットの動作）
コールドプレート２０の下面に、例えばＣＰＵ等の冷却されるべき発熱部品３０を接触させてポンプ２４を駆動する。これにより、第１冷媒流路、第１タンク４１、第２冷媒流路及び第２タンク４２の順で冷媒が循環する。発熱部品３０の発熱はコールドプレート２０に伝達される。コールドプレート２０に伝達された熱は、第１冷媒流路及び第２冷媒流路を流通する冷媒を介してフィン２２に伝達される。これにより、フィン２２を介して放熱が行われ、発熱部品３０の温度上昇を抑制することができる。 (Operation of cooling unit)
A heat-generating component 30 to be cooled, such as a CPU, is brought into contact with the lower surface of the cold plate 20 to drive the pump 24 . As a result, the coolant circulates through the first coolant channel, the first tank 41 , the second coolant channel and the second tank 42 in that order. Heat generated by the heat-generating component 30 is transmitted to the cold plate 20 . The heat transferred to the cold plate 20 is transferred to the fins 22 via the coolant flowing through the first coolant channel and the second coolant channel. As a result, heat is dissipated through the fins 22, and the temperature rise of the heat-generating component 30 can be suppressed.

複数の冷却ユニット１１のうち、隣り合う冷却ユニット１１の間には、スリット１３が形成される。スリット１３は、隣り合う冷却ユニット１１の隙間である。本実施形態では、スリット１３は、隣り合う冷却ユニット１１の第３方向間の隙間を指す。これにより、各冷却ユニット１１を設置する際に、互いに冷却ユニット１１同士が干渉することを抑制できるため、冷却装置１が損傷することを防ぐことができる。他方で、隣り合う冷却ユニット１１同士に隙間を設けることで、該隙間に冷却風が流れ込み、ラジエータ２１の冷却性能を低下させる虞がある。 <First Embodiment>
A slit 13 is formed between adjacent cooling units 11 among the plurality of cooling units 11 . A slit 13 is a gap between adjacent cooling units 11 . In this embodiment, the slit 13 refers to the gap between the adjacent cooling units 11 in the third direction. This can prevent the cooling units 11 from interfering with each other when the cooling units 11 are installed, thereby preventing the cooling device 1 from being damaged. On the other hand, providing a gap between the adjacent cooling units 11 may allow cooling air to flow into the gap and reduce the cooling performance of the radiator 21 .

＜遮閉部材＞
遮閉部材１２の少なくとも一部は、スリット１３内に配置される。遮閉部材１２がスリット１３内に配置されることで、スリット１３に冷却風が流れにくくなる。したがって、後述する冷却ファン１４により発せられた冷却風はラジエータ２１に供給され、ラジエータ２１によって、効率よく発熱部品３０の放熱を行うことができる。 <Shielding material>
At least part of the blocking member 12 is arranged within the slit 13 . By arranging the blocking member 12 in the slit 13 , it becomes difficult for the cooling air to flow through the slit 13 . Therefore, the cooling air generated by the cooling fan 14, which will be described later, is supplied to the radiator 21, and the radiator 21 can efficiently dissipate heat from the heat-generating component 30. FIG.

遮閉部材１２は、隣り合う冷却ユニット１１の第３方向側の端面に接触することが望ましい。遮閉部材１２と冷却ユニット１１の第３方向の端面との隙間を無くすことで、さらにスリット１３内への冷却風の流れ込みが抑制される。したがって、冷却ユニット１１のラジエータ２１によって、効率よく発熱部品３０の放熱を行うことができる。 It is desirable that the blocking member 12 is in contact with the end faces of the adjacent cooling units 11 on the third direction side. By eliminating the gap between the blocking member 12 and the end surface of the cooling unit 11 in the third direction, the cooling air is further suppressed from flowing into the slit 13 . Therefore, the radiator 21 of the cooling unit 11 can efficiently dissipate heat from the heat-generating component 30 .

遮閉部材１２は、スリット１３の第２方向端部に設けられていればよい。詳細には、冷却風がスリット１３に入り込む入口に遮閉部材１２を配置することで、スリット１３内に冷却風が流れ込むことを抑制できる。スリット１３内全域に遮閉部材１２を配置する場合と比較して、遮閉部材１２の使用量を低減することができる。 The blocking member 12 may be provided at the end of the slit 13 in the second direction. Specifically, by arranging the blocking member 12 at the entrance through which the cooling air enters the slit 13 , it is possible to suppress the cooling air from flowing into the slit 13 . Compared to the case where the shielding member 12 is arranged in the entire slit 13, the usage amount of the shielding member 12 can be reduced.

本実施形態では、遮閉部材１２を第１方向上側からスリット１３に挿入する。なお遮閉部材１２は、第２方向からスリット１３に挿入してもよい。 In this embodiment, the blocking member 12 is inserted into the slit 13 from above in the first direction. The blocking member 12 may be inserted into the slit 13 from the second direction.

遮閉部材１２は、例えば、スポンジやゴムなど弾性を有することが望ましい。スリット１３に遮閉部材１２を挿入する際の挿入性を向上させることができる。具体的には、スリット１３の形状に沿って、遮閉部材１２が変形するため、スリット１３の一部が複雑な形状の場合でも遮閉部材１２を容易に取り付けることができる。また、遮閉部材１２は、弾性を有さない、例えばプラスチックなどの板形状でもよい。 It is desirable that the blocking member 12 has elasticity such as sponge or rubber. Insertability when inserting the shielding member 12 into the slit 13 can be improved. Specifically, since the shielding member 12 deforms along the shape of the slit 13, the shielding member 12 can be easily attached even when a part of the slit 13 has a complicated shape. Alternatively, the shielding member 12 may be in the form of a plate, such as plastic, which does not have elasticity.

カバー部材１５の少なくとも一部は、ラジエータ２１の第１方向の上側に配置される。詳細には、カバー部材１５は、フィン２２の第１方向上側の上面に配置される。冷却風がラジエータ２１の第１方向上側の空間に流れ込むことで、ラジエータ２１の冷却効率が低下する。カバー部材１５をラジエータ２１の第１方向上側の空間に配置することで、該空間へ冷却風が流れることを阻害する。したがって、冷却ユニット１１のラジエータ２１によって、効率よく発熱部品３０の放熱を行うことができる。 At least part of the cover member 15 is arranged above the radiator 21 in the first direction. Specifically, the cover member 15 is arranged on the upper surface of the fin 22 on the upper side in the first direction. The cooling efficiency of the radiator 21 is lowered by the cooling air flowing into the space above the radiator 21 in the first direction. By disposing the cover member 15 in the space above the radiator 21 in the first direction, the cooling air is prevented from flowing into the space. Therefore, the radiator 21 of the cooling unit 11 can efficiently dissipate heat from the heat-generating component 30 .

カバー部材１５は、複数のラジエータ２１に跨って配置される。詳細には、カバー部材１５は、隣り合うラジエータ２１の上面に連続して配置される。この場合、遮閉部材１２の第１方向の上面とカバー部材１５の第１方向の下側の面とが対向する。これにより、カバー部材１５を各ラジエータ２１の上側にそれぞれ配置する場合と比較して、部品点数を削減することができる。また、カバー部材１５を取り付ける作業工数を削減することができる。 The cover member 15 is arranged across the plurality of radiators 21 . Specifically, the cover member 15 is arranged continuously on the upper surfaces of the adjacent radiators 21 . In this case, the upper surface of the blocking member 12 in the first direction faces the lower surface of the cover member 15 in the first direction. Thereby, the number of parts can be reduced compared to the case where the cover member 15 is arranged above each radiator 21 . Moreover, the man-hours for attaching the cover member 15 can be reduced.

遮閉部材１２の第１方向の上面とカバー部材１５の第１方向の下側の面とが接触していてもよい。この場合、スリット１３をより確実に塞ぐことができる。また、カバー部材１５の一部をスリット１３に配置してもよい。 The upper surface of the blocking member 12 in the first direction and the lower surface of the cover member 15 in the first direction may be in contact with each other. In this case, the slit 13 can be closed more reliably. Also, part of the cover member 15 may be arranged in the slit 13 .

＜ファン＞
冷却ユニット１１と第２方向に対向して、ファン１４が設けられる。本実施形態のファン１４は軸流式である。フィン２２が長手方向（第２方向）に延びる方向に冷却風を送風することにより、フィン２２からの放熱を促し、ラジエータ２１の冷却性能が向上する。また、複数のファン１４を冷却ユニット１１と第２方向に対向して配置してもよい。 <Fan>
A fan 14 is provided to face the cooling unit 11 in the second direction. The fan 14 of this embodiment is of the axial type. By blowing the cooling air in the direction in which the fins 22 extend in the longitudinal direction (second direction), heat dissipation from the fins 22 is promoted, and the cooling performance of the radiator 21 is improved. Also, a plurality of fans 14 may be arranged to face the cooling unit 11 in the second direction.

＜第２実施形態＞
次に第２実施形態について説明する。図４は、第２実施形態の冷却装置１を示す平面図である。説明の便宜上、前述の第１実施形態と同様の部分には同一の符号を付す。 <Second embodiment>
Next, a second embodiment will be described. FIG. 4 is a plan view showing the cooling device 1 of the second embodiment. For convenience of explanation, the same reference numerals are given to the same parts as in the above-described first embodiment.

複数の冷却ユニット１１の少なくとも一つが、他の冷却ユニット１１よりも第２方向の冷却風の下流側に配置される。具体的には、一方の冷却ユニット１１Ａに対して、他方の冷却ユニット１１Ｂは、冷却風の下流側に配置される。詳細には、第２方向から見たときに、すべての冷却ユニット１１Ａ、１１Ｂが第２方向に重ならない。より詳細には、各冷却ユニット１１Ａ、１１Ｂのラジエータ２１Ａ、２１Ｂが第２方向に重ならない。第２方向から流れ込んだ冷却風は、上流側の冷却ユニット１１Ａのラジエータ２１Ａに阻害されることなく、下流側の冷却ユニット１１Ｂのラジエータ２１Ｂに流れ込む。したがって、第２方向に複数のラジエータ２１Ａ、２１Ｂを配置した場合でも、全ての冷却ユニット１１Ａ、１１Ｂに効率よく冷却風を流し込むことができる。 At least one of the plurality of cooling units 11 is arranged downstream of the other cooling units 11 in the cooling air flow in the second direction. Specifically, with respect to one cooling unit 11A, the other cooling unit 11B is arranged downstream of the cooling air. Specifically, when viewed from the second direction, none of the cooling units 11A, 11B overlap in the second direction. More specifically, the radiators 21A, 21B of each cooling unit 11A, 11B do not overlap in the second direction. The cooling air flowing in from the second direction flows into the radiator 21B of the cooling unit 11B on the downstream side without being blocked by the radiator 21A of the cooling unit 11A on the upstream side. Therefore, even when a plurality of radiators 21A and 21B are arranged in the second direction, it is possible to efficiently flow cooling air into all of the cooling units 11A and 11B.

それぞれの冷却ユニット１１Ａ、１１Ｂのラジエータ２１Ａ、２１Ｂのフィン２２Ａ、２２Ｂは第２方向に延びる。換言すると、各冷却ユニット１１Ａ、１１Ｂのフィン２２Ａ、２２Ｂが伸びる方向は同じである。 Fins 22A, 22B of radiators 21A, 21B of respective cooling units 11A, 11B extend in the second direction. In other words, the directions in which the fins 22A and 22B of the cooling units 11A and 11B extend are the same.

冷却ユニット１１Ａと冷却ユニット１１Ｂの間に遮閉部材１２Ａを設けてもよい。隣り合う冷却ユニット１１Ａの間を通った冷却風が、冷却ユニット１１Ａと冷却ユニット１１Ｂとの間に流れ込むことで冷却ユニット１１Ｂのラジエータ２１Ｂの冷却効率が低下する。冷却ユニット１１Ａと冷却ユニット１１Ｂの空間に遮閉部材１２Ａを設けることで、該空間へ冷却風が流れることを阻害し、冷却風をラジエータ２１Ｂ側へ流し込むことで、ラジエータ２１Ｂの冷却効率が向上する。 A blocking member 12A may be provided between the cooling unit 11A and the cooling unit 11B. Cooling air passing between the adjacent cooling units 11A flows between the cooling units 11A and 11B, thereby reducing the cooling efficiency of the radiator 21B of the cooling unit 11B. By providing the shielding member 12A in the space between the cooling unit 11A and the cooling unit 11B, the cooling air is prevented from flowing into the space, and the cooling air is flown toward the radiator 21B, thereby improving the cooling efficiency of the radiator 21B. .
