2 Introduction
The 2031A Quick Stick heat pipe operates on a continuous, closed loop
two-phase cycle. The heat from TPW cell boils the refrigerant, causing a cool-
ing effect within the evaporator portion of the tubing. The refrigerant travels
upward to the condenser as a vapor. The dry ice/alcohol mixture cools the va-
por and condenses it back to a liquid. The refrigerant travels back down the
walls of the tube to the bottom where cycle begins again. In this way, the Quick
Stick draws the heat out of the water in the TPW cell until an ice mantle is
frozen around the reentrant tube.
