Cooling loop, in particular for a motor vehicle, and sensor fitted on board the loop
The present invention relates to a cooling loop, in particular for a motor vehicle, the loop being configured to allow a heat exchange between a cooling liquid and a liquid to be cooled. According to the invention, the cooling loop includes an on-board sensor which is positioned at least partially in contact with the cooling liquid, the sensor being configured to supply at least one datum relating to at least one physical property and/or chemical property of the cooling liquid.
1. A heat exchanger comprising a sensor for embedding in a cooling loop for a motor vehicle, the cooling loop being configured to allow a heat exchange between a cooling liquid and a liquid to be cooled, the sensor being configured to be positioned at least partially in contact with the cooling liquid and being configured to provide a measurement of a solute concentration of the cooling liquid, the measurement being obtained by taking account of the electrical conductivity and the viscosity of the cooling liquid, the sensor including a probe configured to be brought into contact at least partially with the cooling liquid, the cooling liquid being in flow or at rest, the heat exchanger further comprising a header tank for circulating the cooling liquid, and a removable flange configured to be connected to the header tank and to allow a connection of a tube for a passage of the cooling liquid between the tube and the header tank through the removable flange, the sensor being positioned on the removable flange.
2. The heat exchanger as claimed in claim 1 , wherein the header tank includes an opening configured to selectively receive the sensor or a closure cap.
