Tank for urea solution of a vehicle

A tank for a urea solution, said tank comprising:

• at least one wall which is made of plastic defining a closed volume configured to contain said urea solution;
• conditioning means configured to maintain said urea solution within a preset temperature range between a maximum threshold and a minimum threshold,
• said conditioning means generating a heat flow adapted to maintain said urea solution within said temperature range by converting an electric power supply of said conditioning means;
• wherein said conditioning means comprises at least one Peltier cell;
• said at least one Peltier cell comprises a first plate in contact with said at least one wall and a second plate connected to said first plate on the opposite side of a thermoelectric connection material;
• and
• a urea solution intake unit fluidically connected to a cooling circuit of an engine of said vehicle, wherein said urea solution intake unit is configured to be activated to heat said incoming urea solution when the temperature of said urea solution falls below said minimum threshold despite said conditioning device having been activated to heat said urea solution;
• wherein the first plate which is made of a conductive material is co-moulded to said at least one wall which is made of plastic defining one inner face of the tank positioned for contact with the urea solution.
