Abstract
A tunable oscillating heat pipe system that includes an oscillating closed loop heat pipe configured for movement of a fluid in an internal passage in the closed loop to transfer heat from a first portion of the closed loop to a second portion. The heat pipe system further includes a valve arranged in a section of the internal passage movable between an open position and a closed position. In the open position, the valve is arranged to permit movement of the fluid in the internal passage and in the closed position, the valve is arranged in the internal passage to limit movement of the fluid in a part of the internal passage. Movement of the valve between the open position and the closed position can be a function of at least one of temperature at the first portion, temperature at the second portion, or temperature at the valve.
