Description
第1部材、第2部材および第3部材にアルミナを用い、環状体および環状体にCu(銅)を用いて、上述した製造方法により放熱デバイスを製造した。製造した放熱デバイス(以下、「実施例に係る放熱デバイス」と記載する)の寸法は、以下の通りである。
外寸(幅×長さ×厚み):50mm×50mm×0.5mm
溝形成領域よりも外方に位置する枠領域の幅:10mm
貫通孔の開口径:1.7mm
圧入前環状体の寸法(外径×内径×厚み):8mm×0.9mm×0.2mm
圧入前塊状体の外径:1.2mm
図22は、第1変形例に係る放熱デバイス1の構成を示す模式的な断面図である。図22に示すように、放熱デバイス1の容器2は、第1部材10の上面111(第5面)に窪み面112を有していてもよい。この場合、貫通孔141a(開口部の一例)は、窪み面112に開口していてもよい。また、鍔部の一部である環状体52の第1部位521は、窪み面112に位置していてもよい。かかる構成とすることで、放熱デバイス1を薄型化することができる。また、この場合、封止部5の平坦面512(封止部5のうち窪み面112から最も突出した面)は、第1部材10の上面111より低くてもよい。かかる構成とすることにより、放熱デバイス1のさらなる薄型化を図ることができる。
上述した実施形態では、封止部5が塊状体51および環状体52の2つの部材を含む場合の例について説明したが、封止部5は、単一の部材であってもよい。この場合の例について図23を参照して説明する。図23は、第2変形例に係る放熱デバイス1の構成を示す模式的な断面図である。
