AI Technical Summary
Technical Problem
Existing vehicle cooling systems require bulky expansion tanks at the top of the cooling circuit, which constrain vehicle design and alter cooling performance when managing coolant pressure instead of volume.
Method used
A lyophobic heterogeneous system using a nanoporous material is integrated into the cooling circuit to absorb coolant expansion, allowing the coolant to enter and exit the material based on pressure changes, eliminating the need for a top-mounted expansion tank.
Benefits of technology
This solution optimizes cooling efficiency and reduces space constraints by allowing coolant expansion systems to be positioned strategically, improving packaging and performance while maintaining consistent pressure.

Abstract
The invention relates to a cooling circuit (12) for a vehicle (10), comprising: - a main mover (11), - a coolant for cooling said main mover (11), and - at least one coolant expansion system (16), wherein the at least one coolant expansion system (16) is a lyophobic heterogeneous system including a nanoporous material, the coolant being a non-wetting liquid on the porous material at a standard pressure of the coolant and capable to enter the nanoporous material upon an increase in coolant pressure.
