Claims (6)
- 方形状の外板体と方形状の内板体とで構成され、両者の間に真空加熱処理により作出される真空層が設けられた方形板状の真空断熱材の製造方法であって、前記外板体と前記内板体の各々は四周縁部に立ち上がり壁を有し、また、前記外板体は前記内板体に比して大きく形成され、更に、前記外板体と前記内板体とは両者を重合せしめて板状体を形成した場合、前記外板体の立ち上がり壁の内側に前記内板体の立ち上がり壁が配される構成であり、前記板状体内の空間に前記真空加熱処理の加熱に耐え得る耐熱性介在物を配設せしめ、前記外板体の立ち上がり壁と前記内板体の立ち上がり壁の間に形成される該立ち上がり壁同士の間の空隙の開口部が上方を向くようにし、前記開口部に該開口部の一部を塞ぐ量のロウ材を前記板状体の四辺に配した後、前記真空加熱処理し、前記空間を真空にした後、前記ロウ材で前記空隙を封止することを特徴とする真空断熱材の製造方法。
- 請求項1記載の真空断熱材の製造方法において、前記外板体と前記内板体とで形成される前記空間を約500℃以上の高温下で前記真空加熱処理することを特徴とする真空断熱材の製造方法。
- 請求項1,2いずれか1項に記載の真空断熱材の製造方法において、前記耐熱性介在物としてセラミックから成る耐熱性介在物を採用したことを特徴とする真空断熱材の製造方法。
- 請求項1〜3いずれか1項に記載の真空断熱材の製造方法において、前記耐熱性介在物を板状としたことを特徴とする真空断熱材の製造方法。
- 請求項1〜4いずれか1項に記載の真空断熱材の製造方法において、前記外板体の内面または前記内板体の内面のいずれか一方若しくは双方に、銅,アルミ,銀若しくはニッケルなどの熱輻射材から成る熱輻射層を形成したことを特徴とする真空断熱材の製造方法。
- 請求項1〜5いずれか1項に記載の真空断熱材の製造方法において、前記真空断熱材を複数組み合わせて形成することを特徴とする断熱容体の製造方法。
