The temperature-controlling characteristics of a thermal mechanical package (TMP) are crucial to the experiments in inertial confinement fusion. This study addresses the semi- and holo-TMP structures. The influences of relative factors

including the pressure of helium inside the hohlraum

width of bulge loops

and power of heat rings

on the temperature-controlling characteristics of TMP are investigated systematically. The results show that a semi-TMP structure has a better temperature-control performance than a holo-structure under the same thermal conditions. Increasing the pressure of helium makes a positive but limited contribution to the TMP temperature-control effect. The presence of bulge loops enhances the heat transfer between the TMP and gold hohlraum

thereby improving the temperature-control performance. In addition

the widths of the bulge loops slightly improve the temperature-controlling effect. The temperature response of the gold hohlraum to variations in the heat ring power exhibits clear differences between the semi- and holo-TMP structures. As the heating power increases

the maximum temperature difference of the gold hohlraum increases linearly at a rate of 0.38 K/W and 0.25 K/W for the semi- and the holo-TMP structures

respectively

which indicates a better temperature-controlling effect on the semi-TMP structure.
