Abstract: A system comprises on the one hand a spiral plate exchanger coiled around a principal axis of the exchanger, in particular oriented vertically, so as to delimit a first fluid flow channel having a cross section in the shape of a spiral discharging at a first axial extremity of the exchanger at an inlet zone of which the overall size is contained within a crown, and on the other hand a distribution device configured in order to supply in a homogeneous manner the whole of the surface of the said crown with at least a first fluid, in particular a liquid.

Abstract: The system comprises a plurality of first fluidic flow channels and a distribution device fed by a flow of a first fluid, notably a liquid, and injecting the flow of first fluid into the plurality of first channels at an output of the distribution device. The output of the distribution device consists of an distribution element for the first fluid, notably formed in a porous material, configured in such a way as to be passed through by the first fluid with a pressure drop such that the first fluid leaves from the distribution element with a uniform surface distribution at an output surface of the distribution element, in a way that ensures a uniform feed of first fluid for the first channels.

Abstract: Embodiments of the present invention relate generally to improved cooling systems and methods for use on aircraft trolleys and compartments. The systems use absorptive cooling with thermal conductive plates strategically positioned in order to keep trolleys and their contents cooled.

Abstract: Method for orientation of a solar panel device (3), wherein the solar panel device is oriented with respect to at least one axis (5), in a first direction and in a second direction, using energy from a first fluid reservoir (6) or a second fluid reservoir (8), the energy being provided by the solar radiation and the two reservoirs being independent, and wherein the solar panel device is oriented with respect to the axis (5), in the first direction or in the second direction, until a distributor valve (13, 14) prevents feeding of one of the actuator chambers by one of the chambers of a reservoir.
