。(Problem to be solved) The natural circulation force of the loop heat pipe described above is caused by the difference in gas density between the exhaust heat cooling product and the gas density at the piping (6). It can be said that this is caused by the difference in the specific gravity of the gas and the specific gravity of the liquid flowing through the pipe (2), but the gas pipe (6) contains not only vaporized gas but also the working fluid present in the liquid tank (11) of the heat generating part (2). are also included in the gas as minute particles and travel together with the gas.Therefore, piping (
When the apparent specific gravity of the gas moving through the pipe increases, and the difference in specific gravity with the liquid in the pipe becomes smaller, the natural circulation force decreases. In addition, there was a problem that the efficiency of the exhaust heat cooling system (insects also decreased and the heat transport capacity was reduced.
6) How to remove the liquid valve contained in the gas flowing through the loop heat pipe was a critical issue in order to increase the natural circulation force and heat transport capacity of the loop heat pipe.
