A liquid-gas heat exchanger for use in a heat exchange system using solar energy has an insulated chamber adapted to allow hot air to pass therethrough. A coil member extends through the insulated chamber and is adapted to allow a heat transfer liquid to pass into and then out of the insulated chamber. The spacing between the windings of the coil are predefined and the coil is in a predetermined position inside the insulated chamber, so as to force the air to pass in between the coil windings and increase the air contact with the coil and provide a large heat exchange. Several baffle members are placed each side of the coil member and an interior area of the insulated chamber and force air to circulate multiple times through the coil member, thereby allowing for an efficient exchange from the hot air to the heat transfer liquid. The insulated containe contains the heat exchanger which is comprised of a plurality of chambers, wherein each the plurality of chambers has a repeating pattern of shapes wherein each of the chamber of th plurality of chambers consists of one deflector which deflector being opposite to another deflector, which other deflector is a mirror image of its opposite deflector but shifted approximately half a the wall length. Each of the deflectors is defined by a specific sequence of components starting with a rounded wall from which extends a shear barrier and the wall is terminated by a diverter.
