光源装置Light source device
　本発明は、光を出射する光源部を備える光源装置に関する。 The present invention relates to a light source device including a light source unit that emits light.
　従来、光源装置として、光を出射する光源部と、光源部を収容する本体部とを備える光源装置が、知られている（例えば、特許文献１）。光源装置は、ファンを備えており、該ファンは、本体部の給気口から排気口に向けて送風している。これにより、発熱する光源部は、風に冷却される。 Conventionally, as a light source device, a light source device including a light source unit that emits light and a main body unit that houses the light source unit is known (for example, Patent Document 1). The light source device includes a fan, and the fan blows air from the air supply port of the main body toward the exhaust port. Thereby, the light source part which generate | occur | produces heat is cooled by a wind.
　ところで、光学装置は、光源部の他に、回路基板及び電子部品といった精密な部品からも発熱する。しかしながら、斯かる精密な部品は、塵や埃により、誤動作や損傷する可能性があるため、防塵処理されたクリーンな風で冷却される必要がある。 Incidentally, the optical device generates heat not only from the light source part but also from precision parts such as a circuit board and electronic parts.

日本国特開２０１０－８９０５号公報Japanese Unexamined Patent Publication No. 2010-8905
　よって、本発明は、斯かる事情に鑑み、所定の被冷却体を防塵処理された風で冷却することができる光源装置を提供することを課題とする。 Therefore, in view of such circumstances, an object of the present invention is to provide a light source device capable of cooling a predetermined object to be cooled with wind subjected to dust-proofing treatment.
　本発明に係る光源装置は、光を出射する光源部と、第１給気口及び第１排気口を有し、前記光源部を収容する本体部と、第２給気口及び第２排気口を有し、冷却されるべき被冷却体を収容する収容部と、前記第１給気口から前記第１排気口に向けて送風する第１送風部と、前記第２給気口から前記第２排気口に向けて送風する第２送風部と、前記第２給気口に配置される防塵部と、を備え、前記本体部は、風の通路である第１通路部と、風の通路であって、前記第１通路部の下流側に隣接される第２通路部とを備え、前記第２通路部のうち風が通過可能な有効断面積は、前記第１通路部のうち風が通過可能な有効断面積よりも、小さく、前記第２給気口は、前記本体部の外部に連通するように配置され、前記第２排気口は、前記第２通路部に連通するように配置され、前記第１送風部の送風能力は、前記第２送風部の送風能力よりも、大きい。 The light source device according to the present invention includes a light source unit that emits light, a first air supply port, and a first exhaust port, and a main body unit that houses the light source unit, a second air supply port, and a second exhaust port. A housing part for housing the object to be cooled, a first air blowing part for blowing air from the first air supply port toward the first exhaust port, and the second air supply port from the first air supply port. 2 The 2nd ventilation part which blows toward the exhaust port, and the dust prevention part arrange | positioned at the said 2nd air supply port, The said main-body part is the 1st channel | path part which is a wind path, and a wind path | route A second passage portion adjacent to the downstream side of the first passage portion, and an effective cross-sectional area of the second passage portion through which wind can pass is that of the first passage portion. It is smaller than the effective cross-sectional area that can pass through, the second air supply port is arranged to communicate with the outside of the main body, and the second exhaust port is connected to the second passage portion. It is arranged so as to communicate, the blowing capacity of the first blower unit, than blowing capacity of the second blower, large.
　本発明に係る光源装置によれば、光を出射する光源部を収容する本体部は、第１給気口及び第１排気口を有している。そして、第１送風部が、第１給気口から第１排気口に向けて送風するため、光源部は、冷却される。 According to the light source device according to the present invention, the main body unit that houses the light source unit that emits light has the first air supply port and the first exhaust port. And since a 1st ventilation part blows toward a 1st exhaust port from a 1st air supply port, a light source part is cooled.
　また、冷却されるべき被冷却体を収容する収容部は、第２給気口及び第２排気口を有している。そして、第２送風部が、第２給気口から第２排気口に向けて送風するため、被冷却体は、冷却される。このとき、防塵部が第２給気口に配置されているため、被冷却体は、防塵部で処理された風で冷却される。 Further, the accommodating portion that accommodates the object to be cooled has a second air supply port and a second exhaust port. And since a 2nd ventilation part ventilates toward a 2nd exhaust port from a 2nd air supply port, a to-be-cooled body is cooled. At this time, since the dustproof part is disposed in the second air supply port, the cooled object is cooled by the wind processed by the dustproof part.
　また、本体部は、風の通路である第１通路部と、風の通路であって、第１通路部の下流側に隣接される第２通路部とを備えている。そして、第２通路部のうち風が通過可能な有効断面積は、第１通路部のうち風が通過可能な有効断面積よりも、小さい。これにより、第２通路部における流速が、第１通路部における流速よりも速くなるため、第２通路部の圧力は、第１通路部の圧力よりも低くなる。即ち、ベンチュリ効果が生じる。 The main body portion includes a first passage portion that is a wind passage and a second passage portion that is a wind passage and is adjacent to the downstream side of the first passage portion. And the effective cross-sectional area which a wind can pass among 2nd channel | path parts is smaller than the effective cross-sectional area which a wind can pass among 1st channel | path parts. Thereby, since the flow velocity in the second passage portion is faster than the flow velocity in the first passage portion, the pressure in the second passage portion is lower than the pressure in the first passage portion. That is, a venturi effect occurs.
　そして、第２給気口が本体部の外部に連通するように配置されていると共に、第２排気口が第２通路部に連通するように配置されている。加えて、第１送風部の送風能力が、第２送風部の送風能力よりも大きいため、上述のベンチュリ効果により、収容部の内部の空気は、第２排気口を経由して、本体部の内部に引かれる。したがって、第２送風部の送風能力よりも大きい風量が収容部の内部を通過することになるため、被冷却体の冷却を促進することができる。 The second air supply port is disposed so as to communicate with the outside of the main body portion, and the second exhaust port is disposed so as to communicate with the second passage portion. In addition, since the air blowing capacity of the first air blowing unit is larger than the air blowing capacity of the second air blowing unit, due to the above-described venturi effect, the air inside the housing portion passes through the second exhaust port, Pulled inside. Therefore, since the air volume larger than the air blowing capability of the second air blowing part passes through the inside of the housing part, the cooling of the cooled object can be promoted.

　斯かる構成によれば、第２送風部である少なくとも一つのファンが、第２給気口に配置されているため、ファンにより第２給気口から空気が給気され、収容部の内部に押し込まれた空気により、収容部の空気が第２排気口から排出される。これにより、収容部の内部の圧力は、本体部の外部の圧力よりも高くなるため、収容部の内部の空気が、本体部の内部にさらに引かれることになる。したがって、被冷却体の冷却をさらに促進することができる。 According to such a configuration, since at least one fan that is the second air blowing unit is disposed in the second air supply port, air is supplied from the second air supply port by the fan, and is contained in the interior of the housing unit. Due to the pushed-in air, the air in the housing portion is discharged from the second exhaust port.

　本実施形態に係る光源装置１の構成については以上の通りであり、次に、本実施形態に係る光源装置１の冷却風の流れについて、図６を参酌して説明する。 The configuration of the light source device 1 according to the present embodiment is as described above. Next, the flow of the cooling air of the light source device 1 according to the present embodiment will be described with reference to FIG.
　第２送風部８により、空気は、本体部４の外部から開口部４３を経由して、第２給気口６１から収容部６の内部に給入され、第２排気口６２から収容部６の外部で且つ本体部４の内部へ排出される。したがって、風が第２給気口６１から第２排気口６２に向けて流れるため、収容部６に収容される被冷却体５が冷却される。 By the second air blowing unit 8, air is supplied from the outside of the main body unit 4 through the opening 43 into the storage unit 6 through the second air supply port 61, and from the second exhaust port 62 to the storage unit 6. And is discharged to the inside of the main body 4. Accordingly, since the wind flows from the second air supply port 61 toward the second exhaust port 62, the cooled object 5 accommodated in the accommodating portion 6 is cooled.
　このとき、第２送風部８である少なくとも一つのファンが、第２給気口６１のみに配置されているため、ファンにより第２給気口６１から空気が給気され、収容部６の内部に押し込まれた空気により、収容部６の空気が第２排気口６２から排出される。したがって、収容部６の内部の圧力は、本体部４の外部の圧力よりも高くなっている。 At this time, since at least one fan that is the second air blowing unit 8 is disposed only in the second air supply port 61, air is supplied from the second air supply port 61 by the fan, and the inside of the housing unit 6. The air in the housing portion 6 is discharged from the second exhaust port 62 by the air pushed into the air. Therefore, the pressure inside the accommodating portion 6 is higher than the pressure outside the main body portion 4.
　また、第１送風部７により、空気は、第１給気口４１から本体部４の内部に給入され、第１排気口４２から本体部４の外部へ排出される。したがって、風が第１給気口４１から第１排気口４２に向けて流れるため、本体部４に収容される光源部２が冷却される。 Further, the air is supplied from the first air supply port 41 to the inside of the main body unit 4 by the first air blowing unit 7, and is discharged from the first exhaust port 42 to the outside of the main body unit 4. Therefore, since the wind flows from the first air supply port 41 toward the first exhaust port 42, the light source unit 2 accommodated in the main body unit 4 is cooled.
　このとき、第１送風部７により、空気は、第１給気口４１、第１通路部４４、第２通路部４５、第１排気口４２の順に通過する。そして、第２通路部４５の有効断面積が、第１通路部４４の有効断面積よりも小さいため、第２通路部４５における流速Ｖ２が、第１通路部４４における流速Ｖ１よりも速くなる。 At this time, air passes through the first air supply port 41, the first passage portion 44, the second passage portion 45, and the first exhaust port 42 in this order by the first air blowing section 7. And since the effective cross-sectional area of the 2nd channel | path part 45 is smaller than the effective cross-sectional area of the 1st channel | path part 44, the flow velocity V2 in the 2nd channel | path part 45 becomes quicker than the flow velocity V1 in the 1st channel | path part 44.
　これにより、ベンチュリ効果が生じるため、第２通路部４５の圧力は、第１通路部４４の圧力よりも低くなる。しかも、収容部６の内部の圧力が、本体部４の外部の圧力よりも高くなっているため、収容部６の内部の空気は、第２排気口６２を経由して、本体部４の内部に引かれることになる。したがって、第２送風部８の送風能力よりも大きい風量が収容部６の内部を通過することになる。 This causes a venturi effect, so that the pressure in the second passage portion 45 is lower than the pressure in the first passage portion 44. In addition, since the pressure inside the housing portion 6 is higher than the pressure outside the main body portion 4, the air inside the housing portion 6 passes through the second exhaust port 62 and passes through the inside of the main body portion 4. Will be drawn to. Therefore, an air volume larger than the air blowing capacity of the second air blowing part 8 passes through the inside of the housing part 6.
　以上より、本実施形態に係る光源装置１によれば、光を出射する光源部２を収容する本体部４は、第１給気口４１及び第１排気口４２を有している。そして、第１送風部７が、第１給気口４１から第１排気口４２に向けて送風するため、光源部２は、冷却される。 As described above, according to the light source device 1 according to the present embodiment, the main body 4 that accommodates the light source 2 that emits light has the first air inlet 41 and the first exhaust 42. And since the 1st ventilation part 7 ventilates toward the 1st exhaust port 42 from the 1st air supply port 41, the light source part 2 is cooled.
　また、冷却されるべき被冷却体５を収容する収容部６は、第２給気口６１及び第２排気口６２を有している。そして、第２送風部８が、第２給気口６１から第２排気口６２に向けて送風するため、被冷却体５は、冷却される。このとき、防塵部９が第２給気口６１に配置されているため、被冷却体５は、防塵部９で処理された風で冷却される。これにより、精密部品である被冷却体５が誤動作や損傷することを抑制できる。 Further, the accommodating portion 6 that accommodates the cooled object 5 to be cooled has a second air supply port 61 and a second exhaust port 62. And since the 2nd ventilation part 8 ventilates toward the 2nd exhaust port 62 from the 2nd air supply port 61, the to-be-cooled body 5 is cooled. At this time, since the dust-proof portion 9 is disposed in the second air supply port 61, the cooled object 5 is cooled by the wind processed by the dust-proof portion 9. Thereby, it can suppress that the to-be-cooled body 5 which is a precision component malfunctions or is damaged.
　また、本実施形態に係る光源装置１によれば、本体部４は、風の通路である第１通路部４４と、風の通路であって、第１通路部４４の下流側に隣接される第２通路部４５とを備えている。そして、第２通路部４５のうち風が通過可能な有効断面積は、第１通路部４４のうち風が通過可能な有効断面積よりも、小さい。これにより、第２通路部４５における流速Ｖ２が、第１通路部４４における流速Ｖ１よりも速くなるため、第２通路部４５の圧力は、第１通路部４４の圧力よりも低くなる。即ち、ベンチュリ効果が生じる。 Further, according to the light source device 1 according to the present embodiment, the main body portion 4 is adjacent to the first passage portion 44 that is a wind passage and the wind passage that is downstream of the first passage portion 44. And a second passage portion 45. The effective cross-sectional area through which wind can pass in the second passage portion 45 is smaller than the effective cross-sectional area through which wind can pass in the first passage portion 44. As a result, the flow velocity V2 in the second passage portion 45 is faster than the flow velocity V1 in the first passage portion 44, so that the pressure in the second passage portion 45 is lower than the pressure in the first passage portion 44. That is, a venturi effect occurs.
　そして、第２給気口６１が本体部４の外部に連通するように配置されていると共に、第２排気口６２が第２通路部４５に連通するように配置されている。加えて、第１送風部７の送風能力が、第２送風部８の送風能力よりも大きいため、上述のベンチュリ効果により、収容部６の内部の空気は、第２排気口６２を経由して、本体部４の内部に引かれる。したがって、第２送風部８の送風能力よりも大きい風量が収容部６の内部を通過することになるため、被冷却体５の冷却を促進することができる。 The second air supply port 61 is disposed so as to communicate with the outside of the main body portion 4, and the second exhaust port 62 is disposed so as to communicate with the second passage portion 45. In addition, since the air blowing capacity of the first air blowing unit 7 is larger than the air blowing capacity of the second air blowing unit 8, the air inside the housing unit 6 passes through the second exhaust port 62 due to the above-described venturi effect. , Pulled inside the main body 4. Therefore, since the air volume larger than the ventilation capability of the 2nd ventilation part 8 will pass the inside of the accommodating part 6, cooling of the to-be-cooled body 5 can be accelerated | stimulated.
　また、本実施形態に係る光源装置１によれば、第２送風部８である少なくとも一つのファンが、第２排気口６２に配置されておらず、第２給気口６１のみに配置されている。これにより、ファンにより第２給気口６１から空気が給気され、収容部６の内部に押し込まれた空気により、収容部６の空気が第２排気口６２から排出される。 Further, according to the light source device 1 according to the present embodiment, at least one fan that is the second air blowing unit 8 is not disposed in the second exhaust port 62 but is disposed only in the second air supply port 61. Yes. Thus, air is supplied from the second air supply port 61 by the fan, and the air in the storage unit 6 is discharged from the second exhaust port 62 by the air pushed into the storage unit 6.
　したがって、収容部６の内部の圧力は、本体部４の外部の圧力よりも高くなるため、収容部６の内部の空気が、本体部４の内部にさらに引かれることになる。その結果、被冷却体５の冷却をさらに促進することができる。 Therefore, since the pressure inside the housing portion 6 is higher than the pressure outside the main body portion 4, the air inside the housing portion 6 is further drawn into the main body portion 4. As a result, cooling of the cooled object 5 can be further promoted.
　また、本実施形態に係る光源装置１によれば、第１給気口４１と第１排気口４２とが対面して配置されているため、風が本体部４の内部を直線状に通過する。これにより、第１送風部７が第１給気口４１から第１排気口４２に向けて送風する際に、圧損が発生することを抑制できる。したがって、光源部２の冷却を促進することができる。 Moreover, according to the light source device 1 according to the present embodiment, the first air supply port 41 and the first exhaust port 42 are arranged to face each other, so that the wind passes through the inside of the main body 4 linearly. .
