Simple, Low Power, Pumped Two Phase Heat Transport System
(STTS)
Abstract:
Our proposed innovation is a simple two-phase thermal
transport system that's used for temperature control of large,
crewed space vehicles. It's innovation lies in the resolution
of many anomalies that have plagued previous designs. Based on
mixed twophase flow, our system incorporates many innovative
features that result in: efficient thermal management with
minimal electrical power consumption and minimization of cost
by using existing NASA developed hardware. Specifically these
innovations include: a simple low power positive displacement
pump that provides increased pressure for flow stabilization;
a simple, more reliable two-phase accumulator; and, use of
already developed evaporator and condenser hardware. This
innovation is directly applicable to NASA's subtopic 09.02 for
advanced heat transport systems to support human space
missions operating at higher loads and more severe
environments. It provides the needed stable temperature
control, high efficiency and reliable operation that is being
sought by NASA.
Commercial applications would be government programs that
utilize large space platforms requiring very stable thermal
interface temperatures for attached payloads. Such
opportunities would exist on the space station, EOS programs,
as well as any current potential users of capillary pumped
loop technology. The latter could be as a subsystem/component
supplier to large Aerospace contractors developing advanced
platforms for DOD missions. Commercialization activities also
involve using the simplified two phase system as a substitute
for pumped liquid run-around loops. These run-around loops are
typically used in process industries to transfer heat between
widely dispersed heat exchangers.
