1. A heat resistant structure adapted to be used in a passage through which flows a high temperature fluid, comprising:
- a heat resistant metal plate having a smooth outer surface exposed to the fluid;
a layer of ceramic fiber material having a high heat transmission resistance extended along an internal surface of said metal plate;
a plurality of heat conductive bodies each spaced apart from adjacent bodies and each located in close contact with said ceramic fiber layer on a side thereof away from said metal plate, each of said heat conductive bodies being provided with a portion which is in slidable contact with a corresponding portion of the adjacent bodies; and
a plurality of passages provided through each of said heat conductive bodies for passing a coolant therethrough,said heat resistant metal plate being provided with a plurality of projections on said internal surface thereof and each of said plurality of heat conductive bodies being provided with a recess engageable with respective ones of said plurality of projections with said ceramic fiber layer being interposed between each projection and respective recess.

Abstract
A heat resistance structure adapted to be used in a passage of a high temperature fluid, comprises a heat resistant metal plate having a smooth outer surface, a layer of a substance having a high heat transmission resistance extended along an internal surface of the metal plate, and heat conductive bodies provided in close contact with the layer, all being arranged in this order from the outer surface of the structure to the interior of the structure. A plurality of coolant passages are further provided through each of the heat conductive bodies.
