Conditioning system for a urea solution

A management system for a urea solution for a vehicle provided with an internal combustion engine, said management system comprising:

• a tank that includes at least one wall defining a space suitable for housing a urea solution, said tank provided with a management unit able to be partially inserted into said space to aspirate and allow the insertion of said urea solution;
• wherein said management unit comprises a head adapted to cooperate in sealed manner with said tank and configured to allow passage of a first duct and a second duct through said head, said management unit comprising a heat exchanger, housed in said space which fluidly connects said first duct and said second duct;
• a heating circuit comprising said first duct and said second duct and a first valve, said heating circuit being fluidly connectable through said first valve to an engine cooling circuit of an engine of said vehicle;
• a fluid cooling circuit configured to selectively allow the passage of a refrigerant fluid inside said heat exchanger of said management unit when said heating circuit is not in operation;
• a supply circuit for the urea solution, said supply circuit comprising a supply circuit pump connected to one of the first duct or the second duct between the management unit and the cooling circuit, a supply circuit valve, a delivery duct connected to the supply circuit pump and the supply circuit valve, and a suction duct connected to the supply circuit pump and the supply circuit valve, said delivery duct and said suction duct being configured to pass through said head of said management unit to enter inside said tank,
• wherein said fluid cooling circuit and said heating circuit are hydraulically integrated with the engine cooling circuit of said engine of said vehicle, so as to use the same conditioning fluid,
• wherein said fluid cooling circuit comprises an air heat exchanger fluidly connected upstream through an additional duct to said second duct and downstream through a further duct to the first duct, and a fluid cooling circuit pump configured to make a conditioning fluid flow inside said first duct, said second duct, said additional duct, said further duct, and said air heat exchanger when said heating circuit valve prevents the fluid communication of said first duct, said second duct, said additional duct, and said further duct with said engine cooling circuit.
