The present invention refers to a cooling system of slabs used in the roof slabs of constructions and functions creating within the slab, air chambers, joining them by means of conduits specially designed, traversing the slab side to side and over its entire width; so that by those conduits hot air in movement could go out from the slab and fresh air could go in, with natural currents of air or forced air, giving as a result that the slab does not heat excessively with the prolonged sun exposure due to said ventilation obtaining therefore a fresher slab.
