Paper Abstract

In the infrared system, in order to decrease the background radiation and maximize the sensitivity, cooling down the aft-optic components' temperature is a better choice. Some two-phase devices such as grooved heat pipe or loop heat pipe (LHP) were used to link the cold sink and IR aft-optic components. This paper presented the testing results of cryogenic grooved heat pipes which were used in some infrared test systems in the temperature range of 160~210K with different heat load conditions. Also, some experimental results of cryogenic loop heat pipe were introduced in this paper.
