Method for Manufacturing a Heat Exchanger

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method for manufacturing a highly efficient heat exchanger from ceramic materials. The method involves applying a textile material soaked in a ceramic slurry onto the surface of a ceramic base, creating complex three-dimensional ceramic structures after thermal processing and silicon infiltration. These structures substantially increase the surface area and enhance heat transfer performance, making ceramic heat exchangers more efficient, especially for high-temperature applications like recuperator burners.

Use CasesContent extracted from patent full text and abstract with AI.

• Industrial burners and furnaces requiring high-efficiency heat recovery (recuperator burners)
• High-temperature gas-to-gas heat exchangers in ceramic, glass, and metal processing industries
• Energy-efficient HVAC systems subject to corrosive or extreme heat conditions
• Heat exchangers in chemical process plants where metal is unsuitable due to corrosion or temperature limits
• Clean energy and waste heat recovery systems in industrial settings

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly improved heat transfer efficiency due to highly structured and enlarged surface area
• Enables use of ceramics in applications that require resistance to high temperatures and corrosion where metals fail
• Ability to create complex, stable, fine-structured ceramic surfaces not possible with traditional ceramic forming methods
• Potential for more compact heat exchanger designs due to increased efficiency
• Greater longevity and durability in harsh environments (chemical, thermal, corrosive exposure)

Patent Abstract

The invention relates to a heat exchanger composed of ceramic material, in particular for recuperator burners, having a heat exchanger surface which has structures for increasing the surface area. It is proposed according to the invention that the heat exchanger surface is coated on one or both sides, over a ceramic intermediate layer (7), with a ceramic structure (8) which is produced using a textile material (1, 2) soaked in a ceramic slip.
