Description
【発明の詳細な説明】 〔発明の技術分野〕 本発明は多層断熱パネルに関する。[Detailed description of the invention] [Technical field of invention] The present invention relates to multilayer insulation panels.
一般に気体は熱伝導率が低く、断熱性に優れているが、
輻射や対流によってその性能が損なわれてしまう。Gases generally have low thermal conductivity and excellent insulation properties, but
Its performance is impaired by radiation and convection.
このようなことから、従来は輻射率の低いアルミニウム
箔を利用してランダム反射等の出来る形状として作った
いわゆるアルミニウムフォールの断熱パネルが知られて
いる。この断熱パネルにはしわ刊タイプと平面タイプが
ある。しわ付タイプの断熱パネルはアルミニウム箔ＫＬ
−わを付けて積層して前記しわの凹凸に空気層を形成し
た構造のものである。平面タイプの断熱パネルはアルミ
ニウム箔を複数枚１０ｍｍ前後の厚さの枠状スペーサを
介して平行に積層した構造のものである。For this reason, so-called aluminum fall insulation panels have been known, which are made using aluminum foil with a low emissivity and have a shape that allows for random reflection. There are two types of insulation panels: wrinkled type and flat type. The wrinkled type insulation panel is made of aluminum foil KL.
- It has a structure in which layers are laminated with wrinkles and air layers are formed in the unevenness of the wrinkles. A flat type heat insulating panel has a structure in which a plurality of aluminum foils are laminated in parallel with a frame-shaped spacer about 10 mm thick interposed therebetween.
しかしながら、前者のしわ刊タイプ断熱パネルはアルミ
ニウム箔が互に接触するため、断熱性能はよくない。後

導率； ０．０１８ ”’／−ｈ℃） Ｋ 比べて断熱
性能が劣る。However, the former wrinkled type insulation panel has poor insulation performance because the aluminum foils come into contact with each other. The latter flat type insulation panel has better insulation performance than the wrinkled type (the flat type has a heat resistance of 0.028 ””/
Although the wrinkle type is mh (0.037 Kff11/m fart), the construction and assembly are complicated because they are pasted in parallel. In addition, all of the insulation panels use air as a heat insulation layer and are lightweight, but their insulation performance is inferior to that of, for example, rigid polyurethane foam (thermal conductivity: 0.018''/-h°C).
本発明は比較的組立作業が簡単で、がっ軽量。 The present invention is relatively easy to assemble and is lightweight.

ノンガス、クリプトンガス等を挙げることができる。In the present invention, a radiation reflecting film made by coating a plastic film with an At thin film having a low emissivity is laminated on both sides of a frame body to form a panel body, and a plurality of panel bodies are held in the form of a holding frame. The retaining portions formed on the outer surfaces of at least both side walls of the frame are inserted into the plurality of rows of guide rails formed on the inner surfaces of at least both side walls of the holding frame mold, and the panel bodies are stacked with a desired gap between them. Furthermore, a radiation reflective film is pasted on both sides of the holding frame mold, and inside the panel body airtightly surrounded by the radiation reflective film and the holding frame mold, between each panel body and between the panel body and the radiation reflective film. By replacing air with a low thermal conductivity gas and sealing it, a multilayer insulation panel that is easy to assemble, lightweight, and has high heat insulation properties is obtained. That is the main point. Examples of the low thermal conductivity gas used here include sulfur hexafluoride, carbon dioxide, chlorofluorocarbon gas, xenon gas, and krypton gas.
