る。BACKGROUND ART Conventionally, a heat exchanger including an impermeable carbon material as a constituent member has been widely used as a facility for the chemical industry. An impermeable carbon material is a material in which the pores of a carbon base material are impregnated and cured with a thermosetting resin such as phenol-based, furan-based, or divinylbenzene to give impermeability to gas or liquid. It is widely used in large heat exchangers such as shell and tube type and polyblock type.
ところが、上記の不浸透性カーボン材は、樹脂を含浸し
ている関係で使用できる温度が含浸樹脂の耐熱温度まで
に制限を受け、せいぜい200℃程度が限界であった。However, the impervious carbon material is impregnated with resin, and the temperature at which it can be used is limited to the heat resistant temperature of the impregnated resin, and the limit is about 200 ° C. at most.

った。Also, in order to impart impermeability to the carbon substrate, the process of impregnating and curing the resin must be repeated multiple times, which prolongs the manufacturing cycle and causes the strength of the carbon substrate itself to be low. Inevitably, the wall thickness of the material must be increased, and it was extremely difficult to reduce the size and weight.

m程度の厚さで済ますことができ、約30％の軽量化が可
能となる。In addition, glassy carbonaceous materials have higher strength than ordinary carbon materials, which means that the thickness of the members can be made thinner and smaller. For example, conventional impermeable carbon materials (bending strength: about 500 kg / cm 2 ) with a material thickness of 5 mm, glassy carbonaceous material (about 1000 kg / cm 2 ) is 3.5 m
The thickness can be about m, and the weight can be reduced by about 30%.
