Frozen start-up behaviour of low-temperature heat pipes.

Author(s) : FAGHRI A.

Type of article: Article

Summary

This paper examines the time-dependent wall and vapour temperature profiles along the axial length of a low-temperature heat pipe during start-up from the frozen state, and freeze-out during normal operation by applying a subfreezing temperature fluid through the condenser. In addition, the experimental transient frozen start-up wall temperature profile is compared with a two-dimensional numerical phase-change model. A successful start-up method using a pulsed power input is presented.
