Embodiment Construction
[0026] In order to improve the structural strength of the catalytic burner, strengthen the heat transfer process, and improve the heat transfer efficiency of the equipment, a flat micro-heat pipe is used as the heat transfer wall of the burner. The flat micro heat pipe is a kind of element with super thermal conductivity. It is a metal body with a thin plate shape on the outside and a plurality of independently operating micro heat pipes inside. It relies on the internal working fluid flow and phase change to make its own heat transfer efficiency higher than that of the same The material's optimal thermal conductor is thousands of times higher. The partition walls between the micro heat pipes play the role of reinforcing ribs in the structure, which greatly increases the pressure bearing capacity of the flat micro heat pipes.
[0027] Therefore, the integrated design of catalytic combustion heat supply, flat micro heat pipe enhanced heat transfer, and reaction heat absorption ...

The invention discloses a catalytic combustor for wall faces of flat plate micro heat pipes. A combustor body is of a plate fin structure and is formed by welding the flat plate micro heat pipes, a heat conduction plate and copper fins. The combustor body is divided by the heat conduction plate into an upper chamber and a lower chamber, namely, a combustion chamber and a heat conduction chamber. The combustion chamber is defined by evaporation segments of the flat plate micro heat pipes and the copper fins, and the heat conduction chamber is defined by condensation segments of the flat plate micro heat pipes and the copper fins. Combustible gas and air enter the combustion chamber to generate a catalytic combustion reaction to release a great amount of heat, and the heat is transmitted tothe heat conduction chamber through the evaporation segments o f the flat plate micro heat pipes on the wall face of the combustion chamber. Fluid materials are input into the heat conduction cavity,and heat is absorbed to achieve preheating or vaporization. The chamber can also be filled with a catalyst, and the materials absorb heat to achieve a catalytic reaction. Thus, the catalytic combustorcan be widely used for a coupling reaction system of strong heat release and heat absorption.
Description
technical field [0001] The invention relates to a catalytic burner on the wall surface of a flat micro-heat pipe, which belongs to the technical fields of combustible gas catalytic combustion, flat micro-heat pipe, exothermic and endothermic coupling reaction, and the like. Background technique [0002] At present, equipment is developing in the direction of miniaturization, high efficiency, safety and environmental protection. However, at present, electric heating or heat conduction oil heating is often used for heat supply for strong endothermic chemical reaction equipment, and additional electric heating devices or heat conduction oil furnaces are required. Electric energy has problems such as low conversion efficiency of primary energy used for power generation or pollution. However, the heat-conducting oil furnace also has the problems of large system volume, low energy conversion and heat utilization efficiency, and does not meet the requirements of equipment miniaturi...
