Description
なお、本発明の実施形態1に係る液冷式コールドプレート1は、通信機器や映像機器や放送機器などの電子装置に限らず、高熱を発する電子部品を実装した回路基板を備える電子装置であれば、本発明を適用することは可能である。
本発明の実施形態1に係る液冷式コールドプレート1は、図1に示すように、金属パイプ3と、コールドプレート本体2と、金属パイプ固定金具(1)41と、金属パイプ固定金具(2)42と、カプラ61とから構成されている。また、液冷式コールドプレート1は、金属パイプ3内に水等の冷却液が供給され、コールドプレート本体2に埋設された金属パイプ3の扁平管直線部3bの真上に配置された高熱を発する電子部品(以下、高発熱部品という)201(図1(a)のn部)から熱を奪うことにより、高発熱部品201の冷却を行う。
なお、図1に記載した複数の高発熱部品201は、液冷式コールドプレート1の構成部品ではなく、液冷式コールドプレート1との間の配置関係を示すためのものであり、液冷式コールドプレート1と個々に接触する場合だけでなく、図示していない回路基板等に実装された状態で纏まって接触する場合もある。また、高発熱部品201直下の金属パイプ3を扁平管にしているが、扁平管以外の丸管等であってもよい。
なお、金属パイプ3は、例えば銅やステンレス鋼等の材料からできている。
次に、本発明の実施形態1に係る液冷式コールドプレート1の製造方法について、図2~図4を参照して説明する。
金属パイプ3を鋳型内に埋設する前に、まず、図2および図3に示すように、金属パイプ3の丸管直線部3aおよび扁平管直線部3bの所定の箇所(図1(a)のm部で示す高発熱部品201の直下を避けた箇所)を金属パイプ固定金具(1)41および金属パイプ固定金具(2)42の凹溝41a,42a並びに凹溝41b,42bでそれぞれ挟み込んだ後、金属パイプ固定金具(1)41の貫通穴41cおよび金属パイプ固定金具(2)42の貫通穴42cに固定ピン43を挿入し、固定ピン43で圧入固定する。なお、後述する図4で示すように、金属パイプ固定金具(1)41および金属パイプ固定金具(2)42の凹溝が形成された面とは反対側の平面は、コールドプレート本体2の平面より凸となる寸法で設計されており、この凸部を鋳型で挟み込んで押さえることにより、金属パイプ3の位置ずれを小さくする。
つまり、鋳型(1)101の凹溝101aおよび鋳型(2)102の凹溝102aで金属パイプ固定金具(1)41および金属パイプ固定金具(2)42を両側から挟み込んで押さえつけることにより、鋳込み時の金属溶湯の流圧による金属パイプ3の位置ずれや変形を抑えることができ、これによって、金属パイプ3の丸管直線部3aおよび扁平管直線部3bの位置ずれや変形を小さくすることができる。
なお、上記実施例では、金属製の鋳型を用いて上述した凹溝を鋳型に設けるよう説明しているが、例えば鋳型として砂型を用いる場合には、型締めの際に鋳型に凹溝が形成されるように金属パイプ固定金具の寸法を型締め後の鋳型内寸より大きめにしておくことで代用可能である。
また、図4のように、鋳込み造形後、金属パイプ固定金具(1)41および金属パイプ固定金具(2)42はコールドプレート本体2平面より凸形状となるため、液冷式コールドプレート1の表面全体、若しくは、金属パイプ固定金具(1)41および金属パイプ固定金具(2)42の突き出た箇所のみをフライス加工することにより、液冷式コールドプレート1表面の平滑度を確保するようにする。
なお、上記実施例では、金属製の鋳型を用いて上述した凹溝を鋳型に設けるよう説明しているが、例えば鋳型として砂型を用いる場合には、型締めの際に凹穴が形成されるように位置決めピンの突出寸法を型締め後の鋳型変形誤差を考慮した鋳型内寸より大きめにしておくことで代用可能である。
なお、本発明の実施形態2に係る液冷式コールドプレート11は、通信機器や映像機器や放送機器などの電子装置に限らず、高熱を発する電子部品を実装した回路基板を備える電子装置であれば、本発明を適用することは可能である。
本発明の実施形態2に係る液冷式コールドプレート11は、図5に示すように、金属パイプ4と、コールドプレート本体12と、カプラ61とから構成されている。また、液冷式コールドプレート11は、金属パイプ4内に水等の冷却液が供給され、コールドプレート本体12に埋設された金属パイプ4の丸管直線部4bの真上に配置された高熱を発する電子部品(以下、高発熱部品という)201(図5(a)のn部)から熱を奪うことにより、高発熱部品201の冷却を行う。
なお、図5に記載した複数の高発熱部品201は、液冷式コールドプレート11の構成部品ではなく、液冷式コールドプレート11との間の配置関係を示すためのものであり、液冷式コールドプレート11と個々に接触する場合だけでなく、図示していない回路基板等に実装された状態で纏まって接触する場合もある。また、高発熱部品201直下の金属パイプ4を丸管にしているが、丸管以外の扁平管等であってもよい。
なお、金属パイプ4は、例えば銅やステンレス鋼等の材料からできている。
次に、本発明の実施形態2に係る液冷式コールドプレート11の製造方法について、図6を参照して説明する。
鋳型(1)111および鋳型(2)102は、図6に示すように、所定の位置(図5(a)のp部で示すコールドプレート本体12の凹部(1)12aおよび凹部(2)12bに対応する位置)に、それぞれ金属パイプ4の形状に合わせて形成された凸部111aおよび凸部112aを有している。そして、鋳型(1)111および鋳型(2)112が型締めされると、鋳型(1)111の凸部111aおよび鋳型(2)102の凸部112aによって、金属パイプ4の丸管直線部4aおよび丸管直線部4bが同時に挟まれ、金属パイプ4の丸管直線部4aおよび丸管直線部4bの位置決めがなされる。そして、型締めされた鋳型(1)111および鋳型(2)112内に金属溶湯が流し込まれ、図5に示す液冷式コールドプレート11が鋳込み造形される。
つまり、鋳型(1)111の凸部111aおよび鋳型(2)112の凸部112aで金属パイプ4の丸管直線部4aおよび丸管直線部4bを両側から挟み込んで押さえつけることにより、鋳込み時の金属溶湯の流圧による金属パイプ4の位置ずれや変形を抑えることができ、これによって、金属パイプ4の丸管直線部4aおよび丸管直線部4bの位置ずれや変形を小さくすることができる。
図7に示すように、鋳型(1)121および鋳型(2)122は、所定の位置(図5(a)のp部で示すコールドプレート本体12の凹部(1)12aおよび凹部(2)12bに相当する位置)に、それぞれ金属パイプ3の丸管直線部3aの形状に合わせて形成された凸部121aおよび凸部122aと、金属パイプ3の扁平管直線部3bの形状に合わせて形成された凸部121bおよび凸部122bとを有している。そして、鋳型(1)121および鋳型(2)122が型締めされると、鋳型(1)121の凸部121aおよび鋳型(2)122の凸部122aによって金属パイプ3の丸管直線部4aが、また、鋳型(1)121の凸部121bおよび鋳型(2)122の凸部122bによって金属パイプ3の扁平管直線部3bが挟まれ、金属パイプ3の丸管直線部3aおよび扁平管直線部3bの位置決めがなされる。そして、型締めされた鋳型(1)121および鋳型(2)122内に金属溶湯が流し込まれ、図5に示す液冷式コールドプレート11が鋳込み造形される。
つまり、鋳型(1)121の凸部121a,凸部121bおよび鋳型(2)122の凸部122a,凸部122bで金属パイプ3の丸管直線部3aおよび扁平管直線部3bを両側から挟み込んで押さえつけることにより、鋳込み時の金属溶湯の流圧による金属パイプ3の変形を抑えることができ、これにより金属パイプ3の丸管直線部3aおよび扁平管直線部3bの位置ずれを小さくすることができる。
因みに、本発明の実施形態3に係る液冷式コールドプレート81は、実施形態1および実施形態2に係る液冷式コールドプレートの技術を兼ね備えたものである。
また、実施形態2においては、コールドプレート本体内に埋め込まれる金属パイプの位置ずれや変形を小さくするために鋳型に設けた凸部で金属パイプを両側から押さえ込むようにしているが、金属パイプの位置ずれや変形をより小さくするためには、鋳型の凸部の数を増やして金属パイプを押さえる箇所を増やす、つまり、鋳型の凸部の間隔(ピッチ)を密にする必要がある。しかし、鋳型の凸部で金属パイプを押さえる箇所を増やすことによって、コールドプレート本体に形成される凹部の数が増えるため、コールドプレートとしての冷却性能が低下してしまう。
そこで、本実施形態3では、実施形態1および実施形態2の2つの技術を使い、金属パイプ固定金具の数を減らすと共に、金属パイプに金属パイプ固定金具を取り付けた箇所の中間の金属パイプを鋳型の凸部で押さえるようして鋳込み造形することによって、鋳込みの際の金属溶湯が流し込まれる方向や流圧に影響されることなく、金属パイプの位置ずれや変形を更に小さくすることができ、経済的で、更なる冷却性能の向上を図ることができる。
本発明の実施形態3に係る液冷式コールドプレート81は、図8に示すように、金属パイプ3と、コールドプレート本体82と、金属パイプ固定金具(1)41と、金属パイプ固定金具(2)42と、カプラ61とから構成されている。また、液冷式コールドプレート81は、金属パイプ3内に水等の冷却液が供給され、コールドプレート本体82に埋設された金属パイプ3の扁平管直線部3bの真上に配置された高熱を発する電子部品(以下、高発熱部品という)201(図8(a)のn部)から熱を奪うことにより、高発熱部品201の冷却を行う。
なお、図8に記載した複数の高発熱部品201は、液冷式コールドプレート81の構成部品ではなく、液冷式コールドプレート81との間の配置関係を示すためのものであり、液冷式コールドプレート81と個々に接触する場合だけでなく、図示していない回路基板等に実装された状態で纏まって接触する場合もある。また、高発熱部品201直下の金属パイプ3を扁平管にしているが、扁平管以外の丸管等であってもよい。
次に、本発明の実施形態3に係る液冷式コールドプレート81の製造方法について、図9を参照して説明する。
金属パイプ3を鋳型内に埋設する前に、まず、上述した図2および図3と同様に、金属パイプ3の丸管直線部3aおよび扁平管直線部3bの所定の箇所(図8(a)のm部で示す高発熱部品201の直下を避けた箇所)を金属パイプ固定金具(1)41および金属パイプ固定金具(2)42の凹溝41a,42a並びに凹溝41b,42bでそれぞれ挟み込んだ後、金属パイプ固定金具(1)41の貫通穴41cおよび金属パイプ固定金具(2)42の貫通穴42cに固定ピン43を挿入し、固定ピン43で圧入固定する。なお、上述した図4と同様に、金属パイプ固定金具(1)41および金属パイプ固定金具(2)42の凹溝が形成された面とは反対側の平面は、コールドプレート本体82の平面より凸となる寸法で設計されており、この凸部を鋳型で挟み込んで押さえることにより、金属パイプ3の位置ずれや変形を小さくする。
なお、上記実施例では、金属製の鋳型を用いて上述した凹溝を鋳型に設けるよう説明しているが、例えば鋳型として砂型を用いる場合には、型締めの際に鋳型に凹溝が形成されるように金属パイプ固定金具の寸法を型締め後の鋳型内寸より大きめにしておくことで代用可能である。
なお、上記実施例では、金属製の鋳型を用いて上述した凹溝を鋳型に設けるよう説明しているが、例えば鋳型として砂型を用いる場合には、型締めの際に凹穴が形成されるように位置決めピンの突出寸法を型締め後の鋳型変形誤差を考慮した鋳型内寸より大きめにしておくことで代用可能である。
また、金属パイプ固定金具の数を減らす一方、金属パイプに金属パイプ固定金具を取り付けた箇所の中間の金属パイプを鋳型の凸部で押さえるようして鋳込み造形するようにしたので、経済的で、更なる冷却性能の向上を図ることができる。
なお、本発明の実施形態4に係る液冷式コールドプレート31は、通信機器や映像機器や放送機器などの電子装置に限らず、高熱を発する電子部品を実装した回路基板を備える電子装置であれば、本発明を適用することは可能である。
本発明の実施形態4に係る液冷式コールドプレート31の構成は、本発明の実施形態1に係る液冷式コールドプレート1の構成と同様であるが、製造時における金属パイプ3の位置決め方法が異なる。つまり、本実施形態4に係る液冷式コールドプレート31においては、液冷式コールドプレート31を電子装置内に搭載する際、図12に示すように、液冷式コールドプレート31に供給する冷却液の出入り口である2つのカプラ61を相手先であるシェルフ301側の2つのカプラ301aに同時にスライド嵌合させなければならないため、液冷式コールドプレート31の2つのカプラ61の位置精度をより高めるようにしたものである。
次に、本発明の実施形態4に係る液冷式コールドプレート31の製造方法について、図10および図11を参照して説明する。
本発明の実施形態1に係る液冷式コールドプレート1と同様に、図2および図3に示すように、金属パイプ3を鋳型内に埋設する前に、まず、金属パイプ3の丸管直線部3aおよび扁平管直線部3bの所定の箇所(図1(a)のm部で示す高発熱部品201の直下を避けた箇所)を金属パイプ固定金具(1)41および金属パイプ固定金具(2)42の凹溝41a,42a並びに凹溝41b,42bでそれぞれ挟み込んだ後、金属パイプ固定金具(1)41の貫通穴41cおよび金属パイプ固定金具(2)42の貫通穴42cに固定ピン43を挿入し、固定ピン43で圧入固定する。なお、図4で示すように、金属パイプ固定金具(1)41および金属パイプ固定金具(2)42の凹溝が形成された面とは反対側の平面は、コールドプレート本体2の平面より凸となる寸法で設計されており、この凸部を鋳型で挟み込んで押さえることにより、金属パイプ3の位置ずれを小さくする。
なお、カプラ固定金具51は、例えばステンレス等の材料からできている。
つまり、鋳型(1)101の凹溝101aおよび鋳型(2)102の凹溝102aで金属パイプ固定金具(1)41および金属パイプ固定金具(2)42を両側から挟み込んで押さえつけることにより、鋳込み時の金属溶湯の流圧による金属パイプ3の変形を抑えることができ、これによって、金属パイプ3の丸管直線部3aおよび扁平管直線部3bの位置ずれを小さくすることができる。
更に、カプラ固定金具51も鋳型(1)101および鋳型(2)102の所定の箇所に嵌合した状態で鋳込み造形がなされるので、2つのカプラ61の位置ずれを小さくすることができる。
したがって、液冷式コールドプレート31をシェルフ301にスライド接続させる際に、液冷式コールドプレート31のカプラ61とシェルフ301側のカプラ301aとの接続作業が容易に行える。
また、図4のように、鋳込み造形後、金属パイプ固定金具(1)41および金属パイプ固定金具(2)42はコールドプレート本体2平面より凸形状となるため、液冷式コールドプレート1の表面全体、若しくは、金属パイプ固定金具(1)41および金属パイプ固定金具(2)42の突き出た箇所のみをフライス加工することにより、液冷式コールドプレート1表面の平滑度を確保するようにする。
また、液冷式コールドプレートのカプラとシェルフ側のカプラとの接続作業時の作業性を向上させることができる。
