same, the film will be divided into N segment length of DX, solvingafter discrete from the top of evaporation section with top to down iterative. The height of the evaporation section liquid pool is known, through calculation can get the filling rate of each row ofAccording to the type of the j row working medium in the can determine whether the j row pipe in the normal operating temperature range. By formula (22) can be calculated for the steam temperature inside the heat pipe. The flow chart applied to the calculation is presented in Fig. 3.1. Calculation of the internal pipeTo solve the condensation section model and the evaporation section model through iterative tube internal height for liquid film of discrete and the heat transfer parameters of thermal variables. Put the film thickness of each points into the comparisonheat pipes, mainly solved by iterative. The flow chart applied to the calculation is presented in Fig. 3.3. Experimental parameters
