A heating device of an urea solution supply system for a selective catalyst reduction device is disclosed. The heating device of an urea solution supply system for a selective catalyst reduction device is composed of a pump module for supplying an urea solution stored in a storage tank to a selective catalyst reduction device, and is to thaw the urea solution frozen in low temperature conditions. The present invention comprises: a heat exchanger mounted on the outer surface of an exhaust pipe in an exhaust system for a vehicle, and drawing in and out heat exchange air; an air pump mounted on the module body of the pump module, and circulating the heat exchange air to the heat exchanger; and a heat exchange pipe connecting the heat exchanger and the air pump, and mounted on the module body inside the storage tank. |
