Description

本発明は、冷却装置とそれを用いた電子機器に関するものである。   The present invention relates to a cooling device and an electronic apparatus using the same.

例えば、電子機器の一例であるテレビジョン受像機は、表示部の大型化が進み、その結果として、その冷却構造が重要になってきた。   For example, in a television receiver which is an example of an electronic device, the display unit has been increased in size, and as a result, the cooling structure has become important.

すなわち、本体ケースの前面側が表示部となっており、またこの本体ケース内には電子部品が配置され、さらにこの本体ケースの背面側に設けた背面カバーには、複数の放熱フィンを一体に設けていた（例えば、特許文献１参照）。   That is, the front side of the main body case is a display unit, electronic components are arranged in the main body case, and a plurality of heat radiation fins are integrally provided on the back cover provided on the back side of the main body case. (For example, refer to Patent Document 1).

特開平７−３２２１７２号公報JP 7-322172 A

上記従来例で課題となるのは、冷却効果をさらに高めなければならないということである。   The problem with the above conventional example is that the cooling effect must be further enhanced.

すなわち、前記従来例では、本体ケース内の電子部品から発せられる熱を、背面カバーに一体形成した複数の放熱フィンから本体ケース外に放熱させようようとしている。   That is, in the conventional example, heat generated from the electronic components in the main body case is radiated to the outside of the main body case from a plurality of heat radiation fins integrally formed on the back cover.

この点をさらに詳しく説明すると、本体ケース内の熱は、先ず複数の放熱フィンに伝えられ、次に本体ケース外において、放熱フィン間の通風路を上昇する空気に放熱されるようになっている。   To explain this point in more detail, the heat in the main body case is first transmitted to the plurality of heat radiating fins, and then radiated outside the main body case to the air rising through the ventilation path between the radiating fins. .

しかしながら、放熱フィン間の通風路を上昇する空気は、放熱フィンからの熱伝導により直ちに温度上昇し、高温となってしまう。   However, the air rising in the ventilation path between the radiating fins immediately rises in temperature due to heat conduction from the radiating fins and becomes high temperature.

このため、それより上方の放熱フィン部分では、本体ケース内の熱を殆ど放熱することができず、その結果として冷却効果が低いものとなってしまうのであった。   For this reason, in the radiating fin part above it, the heat in the main body case can hardly be radiated, and as a result, the cooling effect becomes low.

そこで本発明は、冷却効果を高めることを目的とするものである。   Therefore, the present invention aims to enhance the cooling effect.

そして、この目的を達成するために本発明の冷却装置は、一面が被冷却機器側、他面が外気側となる熱交換体と、この熱交換体の前記一面側における強制対流を行わせる送風機とを備え、前記熱交換体は、その他面側に、長溝状の通風路が複数形成され、前記他面側における長溝状の通風路には、その通風路の長手方向を分断する第一の仕切体を設け、これにより、所期目的を達成するものである。   And in order to achieve this object, the cooling device of the present invention includes a heat exchanger having one side to be cooled and the other side to the outside air side, and a blower for performing forced convection on the one side of the heat exchanger. A plurality of long groove air passages are formed on the other surface side of the heat exchanger, and the long groove air passage on the other surface side is divided into a longitudinal direction of the air passage. A partition is provided, thereby achieving the intended purpose.

以上のように、本発明の冷却装置は、一面が被冷却機器側、他面が外気側となる熱交換体と、この熱交換体の前記一面側における強制対流を行わせる送風機とを備え、前記熱交換体は、その他面側に、長溝状の通風路が複数形成され、前記他面側における長溝状の通風路には、その通風路の長手方向を分断する第一の仕切体を設けたものであるので、その冷却効果を高めることができる。   As described above, the cooling device of the present invention includes a heat exchanger that has one surface on the cooled device side and the other surface on the outside air side, and a blower that performs forced convection on the one surface side of the heat exchanger, The heat exchanger has a plurality of long groove air passages on the other surface side, and the long groove air passage on the other surface side is provided with a first partition that divides the longitudinal direction of the air passage. Therefore, the cooling effect can be enhanced.

すなわち、本発明においては、熱交換体の一面側（被冷却機器側）においては送風機で強制対流を行わせることで、この熱交換体への熱伝導性を高め、また熱交換体の他面側は外気側としているので、この熱交換体の他面側の通風路を上昇する外気によってこの熱交換体に伝わった熱を放熱することが出来る。   That is, in the present invention, on one side of the heat exchanger (cooled equipment side), forced convection is performed by a blower to increase the thermal conductivity to the heat exchanger, and the other side of the heat exchanger. Since the side is the outside air side, the heat transmitted to the heat exchanger can be radiated by the outside air rising on the ventilation path on the other surface side of the heat exchanger.

また、熱交換体の他面側における長溝状の通風路には、その通風路の長手方向を分断する第一の仕切体を設けたものであるので、放熱フィン間の通風路を上昇する空気は、放熱フィンからの熱伝導により直ちに温度上昇し、高温となっても、前記第一の仕切体によって通風路外に放出されることになる。   In addition, the long groove-like ventilation path on the other surface side of the heat exchanger is provided with the first partition that divides the longitudinal direction of the ventilation path, so that the air rising the ventilation path between the radiating fins The temperature immediately rises due to heat conduction from the heat radiating fins, and even if the temperature becomes high, it is released out of the ventilation path by the first partition.

このため、それより上方の放熱フィンの放熱は、通風路外から新たに進入する外気によって行われることになり、この結果として冷却効果を高めることができるのである。   For this reason, the heat radiation of the radiating fins above it is performed by outside air newly entering from outside the ventilation path, and as a result, the cooling effect can be enhanced.

以下、本発明の実施の形態について、図面を参照しながら説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

（実施の形態１）
図１は、本発明を電子機器の一例として表示装置１に適用したものを示し、この表示装置１は、商店２の軒下３に吊り下げられている。 (Embodiment 1)
FIG. 1 shows an example in which the present invention is applied to a display device 1 as an example of an electronic device, and the display device 1 is suspended under an eaves 3 of a store 2.

前記表示装置１は、図１〜図４に示すように、前面側の表示部４、背面側に電子部品の実装基板５が配置された本体ケース６と、この本体ケース６の前記背面側に配置された冷却装置７と、この冷却装置７の背面側に配置された熱交換体カバー８と、この熱交換体カバー８の背面側に配置された背面カバー９とを備えている。   As shown in FIGS. 1 to 4, the display device 1 includes a display unit 4 on the front side, a main body case 6 in which an electronic component mounting substrate 5 is disposed on the back side, and a back side of the main body case 6. The cooling device 7 arranged, the heat exchanger cover 8 arranged on the back side of the cooling device 7, and the back cover 9 arranged on the back side of the heat exchanger cover 8 are provided.

なお、表示装置１は屋外設置タイプのものであるので、本体ケース６に対して表示部４と冷却装置７は何れも水密的に取り付けられている。   Since the display device 1 is of an outdoor installation type, the display unit 4 and the cooling device 7 are both attached to the main body case 6 in a watertight manner.

また、本体ケース６に対して表示部４と冷却装置７が水密的に取り付けられているので、本体ケース６内の熱（主に表示部４や、実装基板５の電子部品から発生する熱）は冷却装置７によって本体ケース６外に効果的に放出する必要がある。   Further, since the display unit 4 and the cooling device 7 are watertightly attached to the main body case 6, heat in the main body case 6 (mainly heat generated from the display unit 4 and the electronic components of the mounting substrate 5). Needs to be effectively discharged out of the main body case 6 by the cooling device 7.

そこで、本体ケース６内の熱を、左右に並べた三つの冷却装置７によって本体ケース６外に効果的に放出するため、本実施形態では、以下のような構成とした。   Therefore, in order to effectively release the heat in the main body case 6 to the outside of the main body case 6 by the three cooling devices 7 arranged on the left and right, the following configuration is adopted in the present embodiment.

各冷却装置７は、図５〜図８に示すごとく、被冷却機器側（本実施形態では表示部４や、実装基板５側）と、外気側（本実施形態では背面カバー９）に交互に突出する三角波板形状の熱交換体１０と、この熱交換体１０の前記一面側（本実施形態では被冷却機器側である表示部４や、実装基板５側）における強制対流を行わせる送風機１１とを備えた構成となっている。なお、熱交換体１０は、被冷却機器側と、外気側に交互に突出する波板形状としても良く、このような波板形状や三角波板形状は、合成樹脂板、または金属板により簡単に形成することが出来、しかも合成樹脂板、または金属板で形成しても、通風による放熱効果は十分に確保することが出来る。   As shown in FIGS. 5 to 8, each cooling device 7 is alternately arranged on the side to be cooled (in the present embodiment, the display unit 4 or the mounting substrate 5 side) and on the outside air side (in the present embodiment, the back cover 9). A projecting triangular wave plate-shaped heat exchanger 10 and a blower 11 for performing forced convection on the one surface side of the heat exchanger 10 (in the present embodiment, the display unit 4 on the cooled device side and the mounting substrate 5 side). It is the composition provided with. The heat exchanger 10 may have a corrugated shape that alternately protrudes from the cooled device side and the outside air side. Such a corrugated shape and a triangular corrugated shape can be easily formed by a synthetic resin plate or a metal plate. Even if it is formed of a synthetic resin plate or a metal plate, the heat dissipation effect by ventilation can be sufficiently ensured.

そして、以上の構成とすることで、前記熱交換体１０の被冷却機器側には、図６、図７に示すように縦方向の長溝状の通風路１２が形成され、この通風路１２内を送風機１１による送風が図１０に示すごとく、上から下へと流れるようになっている。つまり、本体ケース６内に、籠もっている表示部４や、実装基板５の熱は、送風機１１の送風によって通風路１２部分で、熱交換体１０へと伝達されるようになっている。   And by setting it as the above structure, in the to-be-cooled apparatus side of the said heat exchange body 10, as shown to FIG. 6, FIG. As shown in FIG. 10, the air blown by the blower 11 flows from the top to the bottom. That is, the heat of the display unit 4 and the mounting substrate 5 that are trapped in the main body case 6 is transmitted to the heat exchanger 10 through the ventilation path 12 by the blower of the blower 11.

一方、前記熱交換体１０の外気側には、図５、図６、図８に示すように、縦方向で、しかも長溝状の通風路１３が形成され、この通風路１３内を、自然対流によって外気が下から上へと流れるようになっている。つまり、表示部４や、実装基板５の熱が熱交換体１０の内側に伝達され、この熱交換体１０の外気側においては、通風路１３内を下から上へと自然対流により外気が上昇しているので、この外気で放熱が行われ、その結果として表示部４や、実装基板５の効果的な冷却が行われることになる。   On the other hand, as shown in FIGS. 5, 6, and 8, an air passage 13 having a longitudinal groove shape and a long groove shape is formed on the outside air side of the heat exchanger 10, and natural convection is formed in the air passage 13. As a result, outside air flows from the bottom to the top. That is, the heat of the display unit 4 and the mounting substrate 5 is transmitted to the inside of the heat exchanger 10, and the outside air rises by natural convection from the bottom to the top in the ventilation path 13 on the outside air side of the heat exchanger 10. Therefore, heat is dissipated by the outside air, and as a result, the display unit 4 and the mounting substrate 5 are effectively cooled.

また、熱交換体１０の背面カバー９側に外気が流れるようにするために、熱交換体カバー８は、図２、図３から理解されるように、熱交換体１０の外周と、背面カバー９側に十分な空間を形成した枠形状に形成されている。   Further, in order to allow outside air to flow to the back cover 9 side of the heat exchanger 10, the heat exchanger cover 8 includes an outer periphery of the heat exchanger 10 and a back cover as can be understood from FIGS. It is formed in a frame shape in which a sufficient space is formed on the 9 side.

さらに、背面カバー９にも、図２、図４から理解されるように、複数の通気孔１４が形成されている。   Furthermore, as can be understood from FIGS. 2 and 4, the rear cover 9 is also formed with a plurality of vent holes 14.

本実施形態において特徴的なのは、図２、図５、図６に示すように、上下方向に伸びる長溝状の通風路１３を、その長手方向である上下方向において分断する仕切体１５を設けたことである。   As shown in FIGS. 2, 5, and 6, the present embodiment is characterized in that a partition 15 that divides the long groove-like ventilation path 13 extending in the vertical direction in the vertical direction, which is the longitudinal direction, is provided. It is.

仕切体１５は、長板により形成され、この長板の長手方向の一辺側（熱交換体１０側）には、図６に示すように、熱交換体１０の他面側に設けた外気側の通風路１３内に突入する突入片１６を設けており、これにより上下方向に伸びる長溝状の通風路１３を、その長手方向である上下方向において仕切体１５により分断するようにしている。   The partition 15 is formed of a long plate, and on one side of the long plate in the longitudinal direction (on the heat exchange body 10 side), as shown in FIG. 6, the outside air side provided on the other surface side of the heat exchange body 10 An intrusion piece 16 that enters the air passage 13 is provided so that the long groove-like air passage 13 extending in the vertical direction is divided by the partition 15 in the vertical direction, which is the longitudinal direction thereof.

したがって、熱交換体１０が、表示部４や、実装基板５の電子部品から発生する熱で温度上昇すると、この熱交換体１０の外気側においては、通風路１３内を下から上へと上昇する自然対流が発生し、この外気で放熱が行われ、その結果として表示部４や、実装基板５の効果的な冷却が行われることになる。   Therefore, when the temperature of the heat exchanger 10 rises due to heat generated from the display unit 4 and the electronic components of the mounting substrate 5, the outside of the heat exchanger 10 rises from the bottom to the top in the ventilation path 13. Natural convection occurs, and heat is released by the outside air. As a result, the display unit 4 and the mounting substrate 5 are effectively cooled.

また、この時、長溝状の通風路１３を、その長手方向である上下方向において仕切体１５により分断しているので、この仕切体１５より下の通風路１３から上昇した外気は、この仕切体１５により通風路１３外へと流出される。   At this time, since the long groove-shaped ventilation path 13 is divided by the partition 15 in the vertical direction, which is the longitudinal direction, the outside air rising from the ventilation path 13 below the partition 15 is separated from the partition. 15 flows out of the ventilation path 13.

また、これにより、この仕切体１５より上の通風路１３には新たな外気が流入し、通風路１３内を上昇することになる。   As a result, fresh outside air flows into the ventilation path 13 above the partition 15 and rises in the ventilation path 13.

そしてこの上の通風路１３内においても、この外気で放熱が行われ、その結果として表示部４や、実装基板５の効果的な冷却が行われることになる。   Also in the ventilation path 13 above, heat is radiated by this outside air, and as a result, the display unit 4 and the mounting substrate 5 are effectively cooled.

これに対して、通風路１３内を上下方向に分断していなかった場合には、外気が、その上昇途中で十分に温度上昇し、それ以降は熱交換体１０の冷却にあまり貢献できない状態となる。   On the other hand, when the inside of the ventilation path 13 is not divided in the vertical direction, the temperature of the outside air sufficiently rises in the course of its rise, and after that, the state where it does not contribute much to the cooling of the heat exchanger 10. Become.

なお、図６に示すごとく、突入片１６の先端と、熱交換体１０の他面側間には、水抜き開口１７を設けており、これにより背面カバー９の通気孔１４から浸入した雨水等は、この水抜き開口１７を通して通風路１３内を上方から下方へと流下し、再び背面カバー９外へと流出されることになる。   As shown in FIG. 6, a drain opening 17 is provided between the tip of the entry piece 16 and the other surface side of the heat exchange element 10, so that rainwater or the like infiltrated from the vent hole 14 of the back cover 9. Flows through the drain opening 17 in the ventilation path 13 from the upper side to the lower side and flows out of the back cover 9 again.

また、図９と図２から理解されるように、仕切体１５に対向する熱交換体カバー８部分はフレーム（風路分断桟の一例）８ａが存在し、その部分には、この仕切体１５の背面カバー９側の他辺が突入する凹部１８が設けられている。さらに、この熱交換体カバー８を構成するフレームで、仕切体１５に対向する部分には、図９に示すように背面カバー９の凹部１９に突入する凸部２０が設けられている（背面カバー９の凹部１９部分は、風路分断桟となっている）。   Further, as understood from FIGS. 9 and 2, the heat exchanger cover 8 portion facing the partition 15 has a frame (an example of an air passage dividing bar) 8 a, and the partition 15 A recess 18 into which the other side of the rear cover 9 side enters is provided. Further, in the frame constituting the heat exchanger cover 8, a convex portion 20 that protrudes into the concave portion 19 of the back cover 9 is provided at a portion facing the partition 15 (back cover) as shown in FIG. 9 is a wind path dividing bar).

このため、仕切体１５の部分において通風路１３内は、背面カバー９の外まで、上下方向の分断状態が確保されており、よって仕切体１５の上下における通風路１３内においては、それぞれ下方より進入した外気が通風路１３内を上昇し、それによって熱交換体１０の放熱が行われるので、表示部４や、実装基板５の効果的な冷却が行われることになるのである。   For this reason, the inside of the ventilation path 13 in the part of the partition 15 is ensured in a vertically divided state up to the outside of the back cover 9. Therefore, in the ventilation path 13 above and below the partition 15, respectively. The entered outside air rises in the ventilation path 13, and thereby the heat exchanger 10 is dissipated, so that the display unit 4 and the mounting substrate 5 are effectively cooled.

また、図５、図６に示すように、本体ケース６を縦設置する場合の冷却効果の向上のため、３枚並んだ中央の熱交換体１０の他面側（背面カバー９側）には、仕切体１５に直交する、長板により形成した仕切体２１を設けている。なお、この仕切体２１は、熱交換体１０の通風路１３内に、この通風路１３に沿って設けている。   Also, as shown in FIGS. 5 and 6, in order to improve the cooling effect when the main body case 6 is installed vertically, on the other surface side (back cover 9 side) of the central heat exchanger 10 arranged in a row of three sheets. A partition 21 formed by a long plate orthogonal to the partition 15 is provided. The partition 21 is provided in the ventilation path 13 of the heat exchanger 10 along the ventilation path 13.

つまり、本体ケース６は図１、図２に示すように横長のもので、通常使用はこの横長状態で使用するが、これを縦長状態で使用する場合もあり、その場合に、この仕切体２１によって上下方向の外気上昇経路を分断し、それによって効果的な冷却が行われるようにするのである。   That is, the main body case 6 is horizontally long as shown in FIG. 1 and FIG. 2, and is normally used in this horizontally long state, but may be used in a vertically long state. Is used to divide the upward / downward direction of the outdoor air so that effective cooling can be performed.

もちろん、この仕切体２１に対向する熱交換体カバー８部分には、図２に示すようにフレーム（風路分断桟の一例）８ｂが存在し、その部分には図９と同様に、この仕切体２１の背面カバー９側の他辺が突入する凹部（図示せず）が設けられている。さらに、この熱交換体カバー８を構成するフレームで、仕切体２１に対向する部分（風路分断桟となる）には、背面カバー９の凹部（図示せず）に突入する凸部（図示せず）が設けられている。   Of course, the heat exchanger cover 8 facing the partition 21 has a frame (an example of an air passage dividing bar) 8b as shown in FIG. A recess (not shown) into which the other side of the body 21 on the back cover 9 side enters is provided. Further, in the frame constituting the heat exchanger cover 8, a convex portion (not shown) that enters a concave portion (not shown) of the back cover 9 is provided at a portion facing the partition 21 (becomes an air passage dividing bar). Z).

（実施の形態２）
図１１は本発明の（実施の形態２）を示し、図９に示した仕切体１５に対向するフレームの凹部１８や凸部２０を無くし、その部分にクッション体２２、２３を設けたものである。 (Embodiment 2)
FIG. 11 shows (Embodiment 2) of the present invention, in which the concave portion 18 and the convex portion 20 of the frame facing the partition body 15 shown in FIG. 9 are eliminated, and cushion bodies 22 and 23 are provided in that portion. is there.

具体的には、仕切体１５と熱交換体カバー８間にクッション体２２を設け、熱交換体カバー８と背面カバー９間にクッション体２３を設けたものである。   Specifically, a cushion body 22 is provided between the partition 15 and the heat exchange body cover 8, and a cushion body 23 is provided between the heat exchange body cover 8 and the back cover 9.

（実施の形態３）
図１２、図１３は本発明の（実施の形態３）を示し、（実施の形態１）で使用した熱交換体カバー８を廃止したものである。 (Embodiment 3)
12 and 13 show (Embodiment 3) of the present invention, in which the heat exchanger cover 8 used in (Embodiment 1) is eliminated.

このため、背面カバー９の凹部１９には、仕切体１５の背面カバー９端部を直接突入させている。   Therefore, the end of the back cover 9 of the partition 15 is directly inserted into the recess 19 of the back cover 9.

（実施の形態４）
図１４、図１５は本発明の（実施の形態４）を示し、この実施の形態４における熱交換体２４は、平板２５に、実装基板５側と、背面カバー９側に突出する放熱フィン２６を、所定間隔おいて設け、前記平板２５の背面カバー９側において隣接する放熱フィン２６間を外気側通風路としたものである。 (Embodiment 4)
FIG. 14 and FIG. 15 show (Embodiment 4) of the present invention, and the heat exchange element 24 in this Embodiment 4 is a flat plate 25, a radiating fin 26 protruding to the mounting substrate 5 side and the back cover 9 side. Are provided at predetermined intervals, and the space between the adjacent radiating fins 26 on the back cover 9 side of the flat plate 25 is used as an outside air ventilation path.

もちろんこのような熱交換体２４でも、水抜き開口２７を設けている。   Of course, such a heat exchanger 24 also has a drain opening 27.

なお、（実施の形態２〜４）においては、（実施の形態１）と異なる部分だけを説明しており、基本的な構造は（実施の形態１）と同様になっている。   In (Embodiments 2 to 4), only the parts different from (Embodiment 1) are described, and the basic structure is the same as (Embodiment 1).

以上のように本発明の冷却装置は、一面が被冷却機器側、他面が外気側となる熱交換体と、この熱交換体の前記一面側における強制対流を行わせる送風機とを備え、前記熱交換体は、その他面側に、長溝状の通風路が複数形成され、前記他面側における長溝状の通風路には、その通風路の長手方向を分断する第一の仕切体を設けたものであるので、その冷却効果を高めることができる。   As described above, the cooling device of the present invention includes a heat exchanger having one surface on the side to be cooled and the other surface on the outside air side, and a blower that performs forced convection on the one surface side of the heat exchanger, The heat exchanger has a plurality of long groove air passages formed on the other surface side, and the long groove air passage on the other surface side is provided with a first partition that divides the longitudinal direction of the air flow passage. Therefore, the cooling effect can be enhanced.

すなわち、本発明においては、熱交換体の一面側（被冷却機器側）においては送風機で強制対流を行わせることで、この熱交換体への熱伝導性を高め、また熱交換体の他面側は外気側としているので、この熱交換体の他面側の通風路を上昇する外気によってこの熱交換体に伝わった熱を放熱することが出来る。   That is, in the present invention, on one side of the heat exchanger (cooled equipment side), forced convection is performed by a blower to increase the thermal conductivity to the heat exchanger, and the other side of the heat exchanger. Since the side is the outside air side, the heat transmitted to the heat exchanger can be radiated by the outside air rising on the ventilation path on the other surface side of the heat exchanger.

また、熱交換体の他面側における長溝状の通風路には、その通風路の長手方向を分断する第一の仕切体を設けたものであるので、放熱フィン間の通風路を上昇する空気は、放熱フィンからの熱伝導により直ちに温度上昇し、高温となっても、前記第一の仕切体によって通風路外に放出されることになる。   In addition, the long groove-like ventilation path on the other surface side of the heat exchanger is provided with the first partition that divides the longitudinal direction of the ventilation path, so that the air rising the ventilation path between the radiating fins The temperature immediately rises due to heat conduction from the heat radiating fins, and even if the temperature becomes high, it is released out of the ventilation path by the first partition.

このため、それより上方の放熱フィンの放熱は、通風路外から新たに進入する空気によって行われることになり、この結果として冷却効果を高めることができるのである。   For this reason, the heat radiation of the radiating fins above it is performed by air newly entering from outside the ventilation path, and as a result, the cooling effect can be enhanced.

したがって、例えば、屋外設置タイプの電子機器に利用することが可能である。   Therefore, for example, it can be used for an outdoor installation type electronic apparatus.
