Abstract: PURPOSE: A urea supply system for a selective catalyst reduction device and a control method thereof are provided to effectively cool high temperature fuel returned to a fuel tank from an engine, and smoothly supply a urea solution. CONSTITUTION: A urea supply system for a selective catalyst reduction device comprises a storage tank(10), a pump module(30), and a heating unit(70). The storage tank holds a urea solution. The pump module is installed inside the storage tank, and pumps the urea solution to the selective catalyst reduction. The heating unit is placed inside the pump module, and circulates fuel returning to a fuel tank from a diesel engine to heat the urea solution. The heating unit comprises a heat pipe(71) connected to a return line for supplying return fuel to the fuel tank.
