Abstract
A urea-water injector module is provided. The urea-water injector module includes an injector configured to discharge urea water to purify exhaust gas of a vehicle, a main body having the injector installed therein, and a plurality of heat dissipation plates stacked on an exterior surface of the main body to assist heat dissipation. Further the urea-water injector includes a heat block flange disposed under the heat dissipation plate and configured to obstruct heat from being transferred from an exhaust pipe and a mounting unit disposed under the heat block flange and coupled to the exhaust pipe.
