Hereinafter, the present embodiment will be described in detail based on the drawings. As shown in FIG. 1, the heat dissipation device 1 includes a housing 2, an electrical component 3, a pressing unit 4, a blower unit 5 (see FIG. 2), and a lid 6 (see FIG. 3).
筐体２は、例えば金属製の材料から構成されており、防水、防塵、防爆性能を有している。筐体２は、大型の物体を収容可能な箱形に形成されており、後述する蓋６により密閉可能に構成されている。また、筐体２の側壁には、電気部品３の配線３Ａが通される図示しない孔が形成されている。
The housing 2 is made of, for example, a metal material, and has waterproof, dustproof, and explosion-proof performance. The housing 2 is formed in a box shape that can accommodate a large object, and is configured to be hermetically sealed by a lid 6 described later. Further, a hole (not shown) through which the wiring 3 </ b> A of the electrical component 3 is passed is formed on the side wall of the housing 2.
電気部品３は、比較的大きな部品（例えば、ＰＣ）であり、筐体２内に配置される。電気部品３は、本発明の「発熱体」に対応する。
The electrical component 3 is a relatively large component (for example, PC) and is disposed in the housing 2. The electrical component 3 corresponds to the “heating element” of the present invention.
押し付け部４は、電気部品３が配置され、当該電気部品３を蓋６（図３参照）に向けて押し付ける部分である。図２に示すように、押し付け部４は、台座４１と、支持部材４２と、付勢部材４３と、規制部材４４とを有する。
The pressing portion 4 is a portion where the electrical component 3 is disposed and pressed against the lid 6 (see FIG. 3). As shown in FIG. 2, the pressing unit 4 includes a pedestal 41, a support member 42, a biasing member 43, and a regulating member 44.
台座４１は、電気部品３が載せられる部分であり、矩形の板状に構成されている。支持部材４２は、台座４１を支持する部分であり、台座４１の４角にそれぞれ配置される。
The pedestal 41 is a portion on which the electrical component 3 is placed, and is configured in a rectangular plate shape. The support members 42 are portions that support the pedestal 41, and are respectively disposed at the four corners of the pedestal 41.
支持部材４２は、第１軸４２Ａと、第２軸４２Ｂとを有する。第１軸４２Ａは、筐体２の底部２Ａから立ち上がった部分である。第２軸４２Ｂは、第１軸４２Ａの上端から延びており、第１軸４２Ａよりも径が小さい。第２軸４２Ｂには、台座４１が通される。これにより、支持部材４２は、台座４１を移動可能に支持している。
The support member 42 has a first shaft 42A and a second shaft 42B. The first shaft 42 </ b> A is a portion that rises from the bottom 2 </ b> A of the housing 2. The second shaft 42B extends from the upper end of the first shaft 42A and has a smaller diameter than the first shaft 42A. A pedestal 41 is passed through the second shaft 42B. Thereby, the support member 42 is supporting the base 41 so that a movement is possible.
付勢部材４３は、台座４１を蓋６に向けて付勢するための圧縮バネである。付勢部材４３は、台座４１と第１軸４２Ａとの間に位置するように第２軸４２Ｂに通されている。これにより、付勢部材４３は、図示上方向に台座４１を付勢する。
The urging member 43 is a compression spring for urging the base 41 toward the lid 6. The biasing member 43 is passed through the second shaft 42B so as to be positioned between the base 41 and the first shaft 42A. Thereby, the urging member 43 urges the pedestal 41 upward in the drawing.
規制部材４４は、第２軸４２Ｂの上端部に配置されるキャップであり、台座４１が支持部材４２から脱落することを規制する。
The regulating member 44 is a cap arranged at the upper end portion of the second shaft 42B, and regulates the pedestal 41 from dropping from the support member 42.
送風部５は、筐体２内に風を送ることで筐体２内の熱を拡散するためのファンであり、筐体２内における台座４１の下方に配置されている。
The blower unit 5 is a fan for diffusing heat in the housing 2 by sending air into the housing 2, and is disposed below the pedestal 41 in the housing 2.
図３に示すように、蓋６は、筐体２と同様の材料で構成された蓋であり、筐体２側を向く裏面に放熱部材７を有している。蓋６は、本発明の「放熱部」に対応する。
As shown in FIG. 3, the lid 6 is a lid made of the same material as the housing 2, and has a heat radiating member 7 on the back surface facing the housing 2 side. The lid 6 corresponds to the “heat dissipating part” of the present invention.
放熱部材７は、熱伝導性を有する材料から構成された、弾性の放熱シートである。放熱部材７は、蓋６において、電気部品３の全範囲をカバーできるような範囲に位置している。
The heat radiating member 7 is an elastic heat radiating sheet made of a material having thermal conductivity. The heat dissipating member 7 is located in a range that can cover the entire range of the electrical component 3 in the lid 6.
また、電気部品３は、押し付け部４の台座４１に載せられると、筐体２の側壁よりも突出した位置に、上面が位置する。そのため、蓋６により筐体２を閉じようとすると、電気部品３が蓋６に押されることにより、付勢部材４３の付勢力に抗して下側に下げられる。
Further, when the electrical component 3 is placed on the pedestal 41 of the pressing portion 4, the upper surface is located at a position protruding from the side wall of the housing 2. Therefore, when the casing 2 is to be closed by the lid 6, the electrical component 3 is pushed by the lid 6 and is lowered downward against the urging force of the urging member 43.
言い換えると、押し付け部４は、蓋６で筐体２を密閉することに連動して電気部品３を蓋６に向けて押し付ける。その結果、電気部品３からの熱が蓋６に伝わるので、蓋６により、外部に電気部品３から伝えられた熱を効率よく放熱することができる。
In other words, the pressing unit 4 presses the electrical component 3 toward the lid 6 in conjunction with sealing the housing 2 with the lid 6. As a result, the heat from the electrical component 3 is transmitted to the lid 6, so that the heat transmitted from the electrical component 3 to the outside can be efficiently radiated by the lid 6.
また、蓋６を閉じるだけで電気部品３を蓋６の放熱部材７に接触させることができるので、蓋６の開閉や電気部品３の配線整理など、組み立て、設置の作業性を向上させることができる。
Moreover, since the electrical component 3 can be brought into contact with the heat radiating member 7 of the lid 6 simply by closing the lid 6, it is possible to improve the workability of assembly and installation, such as opening and closing the lid 6 and arranging the wiring of the electrical component 3. it can.
また、蓋６の電気部品３が押し付けられる位置に放熱部材７が位置しているため、放熱部材７が電気部品３に接触することで弾性変形することにより、電気部品３の上面全体を放熱部材７に満遍なく接触させることができる。そのため、電気部品３からの熱をさらに効率よく放熱部材７を介して蓋６に伝えることできる。
Moreover, since the heat radiating member 7 is located at the position where the electric component 3 of the lid 6 is pressed, the heat radiating member 7 is elastically deformed by contacting the electric component 3, so that the entire upper surface of the electric component 3 is dissipated. 7 can be contacted evenly. Therefore, the heat from the electrical component 3 can be transmitted to the lid 6 through the heat radiating member 7 more efficiently.
ところで、筐体２が大型である場合、公差管理がラフであり、発熱体に相当する部品の寸法に応じて放熱部材７の潰れ量を管理する必要が生じる。しかし、本実施の形態では、電気部品３が蓋６に向けて押し付けられるので、電気部品３が接触することによる放熱部材７の潰れ量を容易に管理することができるとともに、容易に電気部品３を放熱部材７に接触させることができる。
Incidentally, when the casing 2 is large, tolerance management is rough, and it is necessary to manage the amount of collapse of the heat radiating member 7 according to the dimensions of the parts corresponding to the heating elements. However, in the present embodiment, since the electrical component 3 is pressed toward the lid 6, it is possible to easily manage the amount of collapse of the heat radiating member 7 caused by the contact of the electrical component 3, and to easily perform the electrical component 3. Can be brought into contact with the heat radiating member 7.
また、防爆性能を有する筐体２の場合、筐体２内部の部品の変更によっては、防爆の認証を再取得する必要があるため、筐体２内部の部品が変更された際にも、部品変更を最小限になるように考慮する必要がある。
Further, in the case of the casing 2 having explosion-proof performance, it is necessary to re-acquire the explosion-proof certification depending on the change of the parts inside the casing 2, so even when the parts inside the casing 2 are changed, the parts Changes need to be considered to be minimal.
しかし、本実施の形態では、付勢部材４３の付勢力により電気部品３を蓋６に押し付けるため、電気部品３が変わるような場合においても、その他の部品を変更することなく、又は、必用最低限の部品の交換のみで、電気部品３を蓋６に押し付けることができる。そのため、防爆性能を有する筐体２において、筐体２内部の部品が変更された際にも、部品変更を最小限に止めることができる。
However, in the present embodiment, the electrical component 3 is pressed against the lid 6 by the urging force of the urging member 43. Therefore, even when the electrical component 3 changes, the other components are not changed or the necessary minimum The electric component 3 can be pressed against the lid 6 only by exchanging a limited number of components. Therefore, in the case 2 having explosion-proof performance, even when the parts inside the case 2 are changed, the change of the parts can be minimized.
また、送風部５が筐体２内に配置されているので、筐体２内の熱を拡散でき、ひいては筐体２全体の熱を効率よく放熱することができる。また、送風部５により電気部品３以外の発熱体を冷却することができる。
In addition, since the air blower 5 is disposed in the housing 2, the heat in the housing 2 can be diffused, and as a result, the heat of the entire housing 2 can be efficiently radiated. Moreover, the heat generating elements other than the electrical component 3 can be cooled by the blower 5.
なお、上記実施の形態では、送風部５が筐体２の台座４１の下方に設けられていたが、本発明はこれに限定されず、例えば、電気部品３に送風部５からの風が当たるような位置に送風部５を配置しても良い。
In the above embodiment, the blower 5 is provided below the pedestal 41 of the housing 2. However, the present invention is not limited to this, and for example, the wind from the blower 5 hits the electrical component 3. You may arrange the ventilation part 5 in such a position.
その他、上記実施の形態は、何れも本発明を実施するにあたっての具体化の一例を示したものに過ぎず、これらによって本発明の技術的範囲が限定的に解釈されてはならないものである。すなわち、本発明はその要旨、またはその主要な特徴から逸脱することなく、様々な形で実施することができる。
In addition, each of the above-described embodiments is merely an example of actualization in carrying out the present invention, and the technical scope of the present invention should not be construed as being limited thereto. That is, the present invention can be implemented in various forms without departing from the gist or the main features thereof.
