Background
The size of the single tube Qmax of the heat pipe is the comprehensive manifestation of the heat transfer performance of the heat pipe, and the single tube Qmax is obtained by adopting a simulation test. According to the principle of conservation of energy, the amount of heat supplied and the amount of heat released should be consistent in the case of sufficient insulation. The heat pipe is arranged on the test bench, when the evaporation section is heated, steam generated by heating the working medium in the heat pipe moves to the condensation section through the heat insulation section and is condensed in the condensation section. When the input heat flow is gradually increased to the dry flow in a proper increment, the temperature of the outer wall of the evaporation section is continuously increased, which shows that the capillary force of the channel is insufficient to overcome the pressure loss of the flowing liquid and steam, and the evaporation section is partially or completely dried due to the lack of the liquid. The maximum heat flow before dry-out occurs becomes its limit heat flow. The heating amount of the heat pipe is adjusted by adjusting the power supply voltage of the heater, and the heat release amount is adjusted by changing the flow rate and temperature of the cooling water. Generally, after the amount of heat supplied is set to a certain value, the amount of heat released is adjusted so that TA (or TE, TC) of the heat pipe matches a target value, and after a thermal steady state is reached, the pipe wall temperatures of the evaporation section, the heat insulation section, and the condensation section, and the amount of heat supplied and the amount of heat released are measured. Next, the amount of heat supplied is increased stepwise, and the same measurement is performed in each step, and the process is repeated until the heat transfer amount reaches the limit.
