FEEDWATER HEATER

摘要

PURPOSE: A water heater is provided to prevent the electric heating unit of a water heater from being damaged by minimizing the wall thinning of the body housing of the water heater. CONSTITUTION: A water heater comprises a body housing(210), an electric heating unit(220) and an impact damping plate(230). The body housing comprises a vapor inlet(211) through which bleed vapor flows into. The body housing comprises an empty space. Heat exchange fluid for the heat exchange with the bleed vapor flows in the electric heating unit. The electric heating unit is installed in the body housing. The impact damping plate comprises a plurality of penetration holes(230a) through which a part of the bleed vapor passes. The impact damping plate is formed convexly toward the vapor inlet in the space between the electric heating unit and the vapor inlet.
