Abstract:

Embodiments of a hybrid fan and active heat pumping system are disclosed. In some embodiments, the hybrid fan and active heat pumping system comprises a fan assembly and an active heat pumping system comprises a heat pump. The active heat pumping system is integrated with the fan assembly and is operable to actively cool or heat air as the air passes through the fan assembly. In some embodiments, the heat pump comprised in the active heat pumping system is a solid-state heat pump, a vapor compression heat pump, or a Stirling Cycle heat pump.

Abstract:

At least one forced convection unit added to a passive heat transport system is operated during transient heat loading periods but not operated under steady state conditions for cooling and maintaining a set point temperature of a chamber or surface. Forced convection is selectively employed based on temperature data and/or set point temperature values. A reject heat transport system includes first and second reject heat sinks each coupled via main and crossover transport tubes to first and second reject heat exchangers, permitting both heat sinks to dissipate heat from first and second thermoelectric heat pumps regardless of whether the first, the second, or the first and second heat pumps are in operation.
