Startup characteristics of a multi-evaporator cryogenic loop heat pipe

Performance of Flexible Evaporator for Loop Heat Pipe Technologies

Steady State Model of a Loop Heat Pipe (LHP) With Coherent Porous Silicon (CPS) Wick in the Evaporator

A theoretical study is conducted to explore the effect of different parameters on the performance of a Loop Heat Pipe (LHP). These parameters are evaporator temperature, condenser temperature, total mass charge, the tube size of piping system, and pumping distance between evaporator and condenser. This paper pres ents a steady state model that describes the thermodynamics, heat transfer, and fl...

An Experimental Investigation of the Transient Characteristics on a Flat-Plate Heat Pipe During Startup and Shutdown Operations

This work presents an experimental investigation of the thermal performance of a flatplate heat pipe during startup and shutdown operations. Using the analytical model developed in a previously study, analytical and experimental results on the effect of input power and cooling heat transfer coefficient on the thermal performance of the heat pipe are presented and discussed. The results indicate...

Testing of a Low-Cost Loop Heat Pipe Design

This paper presents and describes the test campaign of a low-cost Loop Heat Pipes (LHP) design. LHP have been around for many decades now. Their potential as passive heat transfer devices has been widely demonstrated in numerous both groundand space-based applications. One of the major disadvantages of LHP is their inherent high manufacturing cost; this is the main factor why LHP are still conf...
