Abstract: The invention relates to a process for preparing a gelled, dried composition forming a monolithic aerogel with a heat conductivity of less than or equal to 40 mW·m−1·K−1 and derived from a resin of polyhydroxybenzene(s) and formaldehyde(s), to this aerogel composition and to the use thereof. This process comprises: a) polymerization in an aqueous solvent of said polyhydroxybenzene(s) and formaldehyde(s) in the presence of an acidic or basic catalyst, to obtain a solution based on the resin, b) gelation of the solution obtained in a) to obtain a gel of the resin, and c) drying of the gel to obtain a dried gel. According to the invention, step a) is performed in the presence of a cationic polyelectrolyte dissolved in this solvent, and the process also comprises a step d) of heat treatment under inert gas of the dried gel obtained in step c) at temperatures of between 150° C. and 500° C. to obtain the non-pyrolyzed aerogel whose heat conductivity is substantially unchanged, even after exposure to a humid atmosphere.

Abstract: A tank stores a coolant liquid and an engine and/or transmission lubricant for a motor vehicle heat engine, as well as a circuit for the cooling and heat regulation of that engine.The tank has a thermally insulating outer wall including an inlet and an outlet for this liquid, and inside the wall, it comprises heating means that are able to preheat this liquid for the cold engine start of the vehicle.The tank further includes a first compartment for this liquid that is provided with said inlet and said outlet, and at least one other compartment that is appropriate for storing an engine or transmission lubricant and that is separated from the first compartment by a tight partition in a lower zone of the first compartment, these compartments each containing at least one local heating means as heating means.
