A two-phase cooling system with flow boiling

A two-phase, forced-convection cooling system, wherein a closed hydraulic circuit apparatus of a heat transfer refrigerating fluid is provided, comprising:

• means for pumping a refrigerating fluid which, at least in some stretches of the circuit, is two-phase liquid-vapor or multiphase,
• a heat sink-evaporator configured to transfer heat by conduction from a component to be cooled to the refrigerating fluid,
• a condenser, capable of condensing the vapor which develops on the evaporator while simultaneously dissipating into the environment the heat given by the refrigerating fluid both by conduction, convection and radiation and by condensation,
• a tank which also acts as an expansion vessel, or a tank and an expansion vessel which are distinct and connected to each other,
• a plurality of sensors, comprising flow rate, pressure and temperature sensors and an electronic control system of the pump;
• wherein said heat sink-evaporator has a base constituted by a plate made of thermal conductive material, with a lower surface in contact with the element to be cooled and an upper surface on which a plurality of mutually parallel or slightly convergent/divergent fins is present, which fins define a corresponding plurality of channels;
• wherein each of said channels is delimited by two adjacent fins and by the surface of the base itself present therebetween.
