PURPOSE:To attain uniformized temperature distribution and efficient heat dissipation by delivering heat of 1st and 2nd devices causing heat each comprising plural sets and one of which being a redundant system respectively from a high temperature side toward a low temperature side through a heat pipe group, and dispersing the heat. CONSTITUTION:Thermally coupled 1st-4th heat pipe groups 11-14 arranged nearly symmetrically with respect to a panel 10 are imbeded thereto, and a main travelling wave tube (main TWT) 17a, a main high voltage power supply 18a, a redundancy group travelling wave tube (redundancy group TWT) 17b and a redundancy group high voltage power supply 18b are mounted on the panel 10 opposite to the heat pipe groups 1-14. Thus, the heat dissipated from the main TWT 17a and the main high voltage power supply 18a or the redundancy group TWT 17b and the redundancy group high voltage power supply 18b is delivered from the high temperature side toward the low temperature side respectively via the heat pipes 15, 16 respectively and dissipated. Thus, the temperature distribution of the panel 10 is always kept uniform and efficient heat dissipation is attained. |
