| 摘要 |
<p>The invention concerns a device for cooling travelling-wave tubes (26) having a collector (28) preferably operating at high temperature and thermally insulated from the rest of the tube, the device comprising a radiator (15) thermally uncoupled from the satellite body and placed in an orientation such that it disperses heat by radiation into space and a heat exchanging fluid loop (25) between hot exchangers (34, 33) thermally connected to the collectors (28) and the emitting units (30) of the tubes (26) borne by the satellite and a cold exchanger (32) belonging to the radiator (15).</p> |
