Problems solved by technology

Then due to the characteristics of ceramics, the edges or sharp corners of square ceramic sheets are prone to fracture under the action of thermal shock
Moreover, the fixed position is prone to thermal stress concentration, so it is also prone to fracture

Abstract

The invention provides a ceramic heat shield sheet which comprises a fixed part used for being fixed to a heated surface. When in use, a plurality of ceramic heat shield sheets are fixed to the heated surface to cover the heated surface; the ceramic heat shield sheets are mutually and partially overlapped; the fixed part of each ceramic heat shield sheet is covered with one or more adjacent ceramic heat shield sheets.

Description

technical field [0001] The invention relates to a heat shielding structure, in particular to a ceramic heat shielding sheet and a heat-resistant structure using the ceramic heat shielding sheet. Background technique [0002] The use of heat shielding structures on high temperature components can enhance the heat resistance of high temperature components. For example, the combustor of a gas turbine is a high temperature component. Due to the excellent heat resistance of ceramics, some manufacturers make ceramics into flakes, and then use bolts to fix them on the inner wall of the flame tube of the combustion chamber, trying to separate the high temperature in the flame tube from the wall of the flame tube. The ceramic sheets are generally square and joined together to completely cover the inner surface of the flame cylinder. Then, due to the characteristics of ceramics, the edges or sharp corners of the square ceramic sheets are prone to fracture under the action of thermal...
