20120181005 | COMPACT HIGH PERFORMANCE CONDENSER - A thermal management system includes an evaporator and a fluid circuit that directs a cooling medium through a condenser. The example condenser provides improved heat transfer coefficients and stable operation by reducing condensate thickness and films that build up within fluid passages of the condenser to provide improved thermal communication between the cooling medium and a cold plate. Each of the fluid passages defined by the condenser is tapered such that an ever-decreasing flow area in a direction of flow from the inlet toward the outlet is provided. The ever-decreasing area maintains a high shear velocity of the vapor such that the liquid film formed on the walls of the passages remains thin. | 07-19-2012 |
20120206880 | THERMAL SPREADER WITH PHASE CHANGE THERMAL CAPACITOR FOR ELECTRICAL COOLING - A cooling assembly comprises an electronic component, a thermal spreader, a cold plate, and a phase change thermal capacitor. The thermal spreader conducts heat freely between the electronic component, the phase change thermal capacitor, and the cold plate. The cold plate dissipates heat. The phase change thermal capacitor stores undissipated heat in a phase transition of a phase change material. | 08-16-2012 |
