摘要
The present paper proposes general equations for predicting the steady-state behavior of a loop heat pipe, linking its operating temperature to various fluidic and geometrical parameters. The closed-form solutions determined for various loop-heat-pipe operating modes are deduced from the equations of a previously developed numerical model. This new approach of the loop-heat-pipe modeling facilitates the identification of the physical mechanisms that influence its operating behavior. In addition, the transition heat flux between variable and fixed conductance modes can also be estimated. This simplified model has been validated for each loop-heat-pipe operating mode for various geometries and operating conditions. The present model could be a useful tool for the design of loop heat pipes.
