Description

【0001】
【発明の属する技術分野】
本発明は、電気設備、工場生産設備内の温度対策機器等に使用する電子冷却器及び電子冷却装置に関する。
【0002】
【従来の技術】
従来の電子冷却器は、ペルティエ効果を有する電子冷却素子の両面に冷却フィン及び放熱フィンを設けるとともに、冷却フィンに空気取り込み用の冷却ファンと、放熱フィンに放熱用の放熱ファンを設け、電子冷却素子に供給するAC/DC電源及び冷却フィンにより冷却した際に発生する除湿水を処理する排水ユニットを組み込み、1ユニットとして完成させている。
【0003】
そして、冷却する大なる能力を必要とする場合は、電子冷却器を必要数組み合わせている。
【0004】
例えば、図10に示すように、電子冷却器1を並設し、放熱フィン2の表面上部に放熱ファン3を設け、表面下部にAC/DC電源4を設けている。この場合、全体としての電子冷却装置5の幅寸法は電子冷却器1の2個分であり、幅寸法が大になることはない。
【0005】
しかし、放熱ファン3が放熱フィン2の表面上部上方、即ち片側に寄っているため、放熱効果が悪いという問題点がある。
【0006】
そこで、図11に示すように、放熱ファン3を放熱フィン2の表面中央部に設け、放熱ファン3の上方または下方に、AC/DC電源4を設けるスペースがないため、両側の電子冷却器1の間に、両電子冷却器1の電源設置スペース6を設けている。
【0007】
【発明が解決しようとする課題】
図11に示す従来例の場合、両電子冷却器1の間に電源設置スペース6を設けているため、電子冷却装置5としての幅寸法が大になり、電子冷却装置5の大きい設置スペースを要するという問題点がある。
【0008】
また、設置スペースが制限された場合、所要数の電子冷却器1を並設できないという問題点がある。
【0009】
本発明は、前記の点に留意し、複数個の電子冷却器を並設した場合の幅寸法を最小限とし、要求される冷却能力に応じ、都度の設計をせずに容易に設置できる電子冷却器及び電子冷却装置を提供することを目的とする。
【0010】
【課題を解決するための手段】
前記目的を達成するために、本発明の請求項1記載の電子冷却器は、電子冷却素子の両面に設けられた上下方向の冷却フィン及び放熱フィンと、前記冷却フィンの表面側に設けられた冷却ファンと、前記冷却フィンの下方に設けられた水受けと、一端が前記水受けに接続され、他端が前記放熱フィン側へ導出されたパイプと、
前記放熱フィン表面のほぼ中央部に設けられた放熱ファンと、前記放熱フィン表面の上部または下部に設けられ、一方の側面が前記放熱フィンの一方の側面とほぼ同一位置にあり、他方の側面が前記放熱フィンの他方の側面より突出した突出部を有し、前記電子冷却素子に給電する電源とを備えたものである。
【0011】
前記のように構成された本発明の電子冷却器は、電子冷却素子に給電するAC/DC電源が、放熱フィン表面の上部または下部、即ち、放熱フィン表面のほぼ中央部に設けられた放熱ファンの上方または下方に設けられ、電源の一方の側面が放熱フィンの一方の側面とほぼ同一位置にあり、電源の他方の側面が放熱フィンの他方の側面より突出した突出部を有するため、少なくとも2個の電子冷却器を並設して電子冷却装置とした場合、一方の電子冷却器の電源突出部を、他方の電子冷却器の放熱フィン上部または下部の上方に位置させ、他方の電子冷却器の電源突出部を、一方の電子冷却器の放熱フィン下部または上部の上方に位置させることができ、電子冷却装置の幅寸法を増大せずに、最小限にすることができ、要求される冷却能力に応じ、都度の設計をせずに容易に設置することができる。
【0012】
つぎに、本発明の請求項2記載の電子冷却装置は、請求項1記載の電子冷却器が2個並設され、
電源が上部または下部に設けられた一方の前記電子冷却器の電源突出部が、他方の前記電子冷却器の放熱フィン上部または下部の上方に位置し、
電源が下部または上部に設けられた前記他方の電子冷却器の電源突出部が、前記一方の電子冷却器の放熱フィン下部または上部の上方に位置したものである。
【0013】
従って、従来のように、並設された両電子冷却器の間に電源設置スペースを設けずに、幅寸法を最小限にすることができる。
【0014】
請求項3記載の電子冷却装置は、同一構成の2個の請求項1記載の電子冷却器を用い、一方の前記電子冷却器に対し、他方の前記電子冷却器の電源を上下逆の位置に付け変え、請求項2記載の電子冷却装置としたものである。
【0015】
この場合、冷却フィンの下方に水受けが設けられ、放熱フィン表面の上部に電源が設けられた2個の電子冷却器を用い、片側の電子冷却器の電源を、上部から下部に付け変えるのみで、幅寸法が最小限の電子冷却装置を簡単に構成することができる。
【0016】
請求項4記載の電子冷却装置は、同一構成の2個の請求項1記載の電子冷却器を用い、一方の前記電子冷却器に対し、他方の前記電子冷却器を上下逆にし、前記他方の電子冷却器の水受け及びパイプを上部から下部に付け変え、請求項2記載の電子冷却装置としたものである。
【0017】
この場合、片側の電子冷却器の電源を付け変えずに、片側の電子冷却器を上下逆にし、その電子冷却器の上方に位置した水受け及びパイプを、下方に付け変えるのみで、同様に簡単に電子冷却装置を構成することができる。
【0018】
つぎに、請求項5記載の電子冷却装置は、請求項1記載の電子冷却器が3個並設され、
中央部前記電子冷却器の上部または下部に設けられた電源の突出部が、一方の側部前記電子冷却器の放熱フィン上部または下部の上方に位置し、
両側部前記電子冷却器の下部または上部に設けられた電源の突出部が、前記中央部電子冷却器の放熱フィン下部または上部の上方に位置したものである。
【0019】
この場合、中央部電子冷却器の電源突出部の上部または下部の位置に対し、両側部電子冷却器の電源突出部が、その反対側の下部または上部に位置しているため、電子冷却器が3個の奇数の場合であっても、電子冷却装置の幅寸法を最小限にすることができる。

An AC / DC power source supplied to the element and a drainage unit for treating dehumidified water generated when cooled by cooling fins are incorporated to complete one unit.
[0003]
When a large capacity for cooling is required, a necessary number of electronic coolers are combined.
[0004]
For example, as shown in FIG. 10, the electronic coolers 1 are arranged side by side, the radiating fan 3 is provided on the upper surface of the radiating fin 2, and the AC / DC power supply 4 is provided on the lower surface. In this case, the overall width of the electronic cooling device 5 is the same as that of the two electronic coolers 1, and the width does not increase.

The power supply protrusion of the other electronic cooler provided with the power supply at the lower or upper part is positioned above the lower or upper part of the heat radiation fin of the one electronic cooler.
[0013]
Therefore, the width dimension can be minimized without providing a power supply installation space between the two electronic coolers arranged side by side as in the prior art.
[0014]
The electronic cooling device according to claim 3 uses two electronic coolers according to claim 1 having the same configuration, and the power supply of the other electronic cooler is placed upside down with respect to one of the electronic coolers. In other words, the electronic cooling device according to claim 2 is obtained.

The electronic cooling device according to claim 2, wherein the water receiver and the pipe of the electronic cooling device are changed from the upper part to the lower part.
[0017]
In this case, without changing the power supply of the electronic cooler on one side, the electronic cooler on one side is turned upside down, and the water receiver and the pipe positioned above the electronic cooler are simply changed downward. An electronic cooling device can be configured easily.
[0018]
Next, in the electronic cooling device according to claim 5, three electronic coolers according to claim 1 are arranged in parallel,
