摘要

Heat dissipation system, a power converter using such a heat dissipation system, and an associated method of thermal management of the power converter are disclosed. The heat dissipation system includes a condenser, a first cooling loop, and a second cooling loop. The first cooling loop is coupled to the condenser and includes a first two-phase heat transfer device. The second cooling loop is coupled to the condenser and includes a second two-phase heat transfer device. The condenser is disposed above the first and second two-phase heat transfer devices.

說明書

The condenser 114 is configured to receive the first, second, and third portions 124a, 124b, 124c of the two-phase fluid 124. Specifically, the first plenum 114a of the condenser 114 receives the first, second, and third portions 124a, 124b, 124c and mixes the first, second, and third portions 124a, 124b, 124c before directing the two-phase fluid 124 to the second plenum 114b via the plurality of heat exchange tubes 114c. The plurality of heat exchange tubes 114c is used to produce the single-phase fluid 120 by dissipating heat in the two-phase fluid 124 to the ambient air 148a. The fan 114d is used to blow the fluid 148 along the plurality of heat exchange tubes 114c to produce the single-phase fluid 120. As discussed herein, the first, second, and the third cooling loops 111, 121, 131 are configured to supply the first, second, and third portions 120a, 120b, 120c of the single-phase fluid 120 to the respective two-phase heat transfer devices 122, 132, 142. In some embodiments, the condenser 114 is configured to simultaneously direct the first, second, and third portions 120a, 120b, 120c of the single-phase fluid 120 to the respective first, second, and third two-phase heat transfer devices 122, 132, 142. In some other embodiments, the condenser 114 may be configured to sequentially direct the first, second, and third portions 120a, 120b, 120c of the single-phase fluid 120 to the respective first, second, and third two-phase heat transfer devices 122, 132, 142 depending on the corresponding temperature of the first, second, and fourth components 108, 118, 138.
