The paper generalizes and presents the results of development and tests of 15 different variants of ammonia MLHPs with cylindrical evaporators 5 and 6 mm in diameter, which have an active zone length of 20 mm and are equipped with titanium and nickel wicks. As a result of successive efforts aimed at increasing the MLHPs efficiency, it was possible to achieve values of the heat-transfer coefficient close to 162,000 W/m2 °C at a value of the heat flux of about 100 × 104 W/m2. A maximum heat flux value of about 135 × 104 W/m2 was achieved at the heat-transfer coefficient equal approximately to 75,000 W/m2 °C Доп.точки доступа: Vershinin, S.
