Heat pipe is a passive two phase device capable of transferring large rates of heat with a minimal temperature drop. However, it has operating limits that determine its heat transfer capacity, as same as parameters that affect its thermal performance. Accordingly; an analytical model is formed and computer software using LABVIEW is prepared to evaluate the heat transfer capacity and the overall thermal resistance of a heat pipe under steady-state conditions. Moreover; a heat pipe is manufactured and its thermal performance is investigated. Consequently; a test rig consisting of a stand, a...
