PURPOSE: A heater assembly is provided to improve thermal efficiency by increasing the heat-exchange surface of a fluid which is heated by a heater. CONSTITUTION: A heater(100) comprises a substrate, a plurality of heating resistors, and an electrode. A plurality of heating resistors are formed on the substrate. The electrode is formed on the substrate in order to apply power to a plurality of heating resistors. An upper housing(400) covers the upper side of the heater. A lower housing(500) is combined with the upper housing in order to cover the lower side of the heater. The flow passage of the lower housing is connected to the flow passage of the upper housing. The upper penetration hole of the lower housing is connected to the lower penetration hole of the lower housing. |
