Semiconductor components are arranged on circuit boards in rows so that an immersing liquid coolant can flow along each row, as is conventional. At the inlet, the coolant temperature is sufficiently below the temperature of vaporization that the total heat load of the components can be handled without vaporizing the liquid. However, some of the components operate at high power and cause the liquid to vaporize locally. Other components operate at low power and do not cause vaporization.
