Abstract

Various techniques are disclosed for improving airtight two-phase heat-transfer systems employing a fluid to transfer heat from a heat source to a sink while circulating around a fluid circuit, the maximum temperature of the heat sink not exceeding the maximum temperature of the heat source. The properties of those improved systems include (a) maintaining, while the systems are inactive, their internal pressure above the saturated-vapor pressure of their heat-transfer fluid; and (b) cooling their internal evaporator surfaces with liquid jets. Figure 43 illustrates the particular case where a heat-transfer system of the invention is used to cool a piston engine (500) by rejecting, with a condenser (508), heat to the ambient air; and where the system includes a heat-transfer fluid pump (10) and means (401-407) for achieving the former property.
