Design and Simulation of Visual Miniature Loop Heat Pipe

A miniature loop heat pipe (mLHP) with a glass condenser was designed and manufactured. A stress analysis of compensation chamber/evaporator and glass condenser was carried out to confirm strength of loop heat pipe using the software MSC NASTRAN. Results indicate that this new loop heat pipe may meet the design requirements and appear to work well. A performance analysis was made for the heat transfer and the fluid flow characteristics inside the loop heat pipe using the commercial software SINDA/FLUINT. To some extent this miniaturized loop heat pipe help the visualization of phase change phenomena.
