Patent number: 8936121Abstract: A heat exchange block (1) for a motor vehicle, includes at least one heat exchanger (2, 3, 4), wherein the block (1) is intended to be disposed behind a front grille (6) of a vehicle and to be traversed by air originating from an opening in the grille. The block includes a group of louvers (13) that can move between an open position and a closed position in order to modulate the flow of air (A) passing through the heat exchanger (2, 3, 4) and a channel (9) that can be disposed between the opening in the grille and the heat exchange block (1). The heat exchange block is suitable for any motor vehicle, but, in particular, hybrid and electric vehicles.Type: GrantFiled: September 28, 2010Date of Patent: January 20, 2015Assignee: Valeo Systemes ThermiquesInventors: Frederic Vacca, Ngy Srun Ap, Jacques Sigonneau, Manuel Henner, Bruno Demory

Patent number: 5884588Abstract: The cooling circuit of an internal combustion engine of a vehicle includes a thermally insulated reservoir having an inlet duct and an outlet duct. These ducts are connected to the mass of air in a head space either within the expansion vessel in the cooling circuit or within the reservoir itself, in such a way that the inlet and outlet ducts become filled with air when the motor is stopped. This air then physically separates the liquid in the reservoir from that contained in the rest of the circuit, so reducing heat losses.Type: GrantFiled: May 8, 1997Date of Patent: March 23, 1999Assignee: Valeo Thermique MoteurInventors: Ngy Srun Ap, Philippe Jouanny
