Study of a Large Capacity Loop Heat Pipe for the Vehicle Exhaust Heat Utilization

Abstract

This paper describes a steady state model of a Loop Heat Pipe (LHP) and its verification with an experimental result. The constructing model assumed a one-dimensional incompressible flow. Calculations are made for an evaporator, a CC, and transport lines. The interior of the transport lines is concerned by the relationship between temperature and pressure in the gas phase, gas-liquid two phase, or liquid phase. The calculation results were compared with an LHP with water as a working fluid. It had the good agreement with the experimental result.
