Description
Technical field
The present invention relates to a kind of heat storage facilities, the heat storage facilities on a kind of travelling-wave tube.
Background technology
Travelling-wave tube is the important electronic device in the fields such as microwave relay communication, radar, electronic countermeasure and satellite communication.Existing
Development for mechanics of communication is maked rapid progress, and the particularly communication apparatus working time of some special dimension is short, by working environment
Limiting, ambient temperature is more than 55 DEG C, it is impossible to provide cooling system to travelling-wave tube, and travelling-wave tube is proposed the requirement without heat radiation work.
Travelling-wave tube is as radio-frequency power amplifier, and the transformation efficiency of radio-frequency power is 20%～50%, and its energy of 80%～50% is converted into
Heat energy, these heat energy need to be distributed by cooling system, if heat is sent out at the helix of travelling-wave tube, collector electrode etc.
Thermal device is assembled in a large number, by causing the generation of the accidents such as travelling tube helical line fusing, collector lead rupture, i.e. causes travelling-wave tube
Operational failure.And without heat radiation working line wave duct, it is desirable to stream time is 1～30 minute.And under some special environment
The travelling-wave tube used, it is desirable to travelling-wave tube stream time is not grown 1～10 minute, or spatial volume is relatively big, requires row simultaneously
The wave duct time in service life is long, the most reusable often, then when travelling-wave tube works, need to reduce helix, receipts as far as possible
The operating temperature of collector electrode, it is thus achieved that longer travelling-wave tube service life.Therefore, travelling-wave tube works under high temperature is without radiating condition
Time, how by heat distributing from functional device, it is that the long-life is without heat radiation travelling-wave tube problem demanding prompt solution, the here longevity
Life and stream time are two different concepts, and stream time is that single is started shooting the time that can work；And the life-span is
The repeatedly accumulation of start normal and continuous operation time.

Described travelling-wave tube heat storage facilities, described fin is sponge build or fin-type.The thermal conductance of fin
Rate is quickly conducted to phase-change material much larger than the thermal conductivity of phase-change material, the heat assisting pedestal to be distributed by travelling-wave tube.
Described travelling-wave tube heat storage facilities, described pedestal is additionally provided with and makes radiating surface closely agree with traveling-wave tube collector
And make the clamp device that assembling lower surface and travelling-wave tube base plate be in close contact and fix.
Described travelling-wave tube heat storage facilities, described clamp device is screwed hole and screw.
Described travelling-wave tube heat storage facilities, described pedestal, cover plate are made up of metal material.
Described travelling-wave tube heat storage facilities, described metal material is aluminum or rustless steel or copper.
Described travelling-wave tube heat storage facilities, after perfusion phase-change material, described sealing ring is at sealing screw and pedestal
Active force is extruded deformation, seals sealing screw with pedestal, and when being used for preventing travelling-wave tube from working, phase-change material is melted
Seepage under state, affects miscellaneous part work.Sealing ring is made up of macromolecular material, described macromolecular material can be rubber or
Politef.Compared with prior art, the method have the advantages that
This travelling-wave tube heat storage facilities, the gap between pedestal storage cavity and fin filled by phase-change material, in order to increase
Fin and effective contact area of pedestal hot side, pedestal stores cavity and does not do grooving, transmits when travelling-wave tube is worked by fin
To the heat of heat storage facilities by radiating fin quickly, uniform conductive to phase-change material, reduce helix, collector electricity
The operating temperature of pole, extends the use longevity without heat radiation travelling-wave tube that single stream time is not long or spatial volume is bigger
Life.Further, used fin is standard fin, reduces difficulty of processing and the production cost of heat storage facilities.
Pedestal wall to be welded wall to be welded with cover plate uses and welds, and hand-hole, sealing hole use sealing ring and sealing screw to be irrigated
Sealing after phase-change material, it is ensured that phase-change material sealing effectiveness is good, and when preventing travelling-wave tube from working, phase-change material is in molten condition
Lower seepage, affects miscellaneous part work.
