STACKED TYPE PRINTED CIRCUIT ELECTRIC HEATER AND GAS HEATER USING THEREOF

摘要

PURPOSE: A stacked printed circuit electric heater and a gas heater using the same are provided to be used in the high temperature zone of more than 500°C by remarkably reducing a temperature difference between a metal heating element and gas through high heat transfer efficiency. CONSTITUTION: A gas heater(10) includes a heating element unit(11), a housing(12), and a header unit(13). The heating element unit is formed by stacking multiple printed circuit boards having multiple micro channels on the surface. The housing accommodates the heating element unit and is made of insulation and heat transfer material. The header unit is installed in the one side of the housing and flows gas in and out the inside of the housing.
