Description
Technical field
The present invention relates to a kind of interior collector and collector and travelling-wave tubes including the interior collector.
Background technology
Space travelling wave tube is the core devices of space communication, due to space application particular/special requirement and space travelling wave tube not
Recoverability so that reliability turns into one of most important performance of travelling-wave tubes.Space travelling wave tube main heat sink mode is heat loss through conduction,
High-power space travelling wave tube output power, heat consumption is high, and collector radiating pressure is big, solves the radiating of the type traveling-wave tube collector
Problem turns into the key issue for improving its reliability.
Collecting pole structure is generally made up of collector in collector outside metal, insulating porcelain piece, metal in travelling-wave tubes.Electronics is noted
By the high frequency interacting system of travelling-wave tubes, surrender portion of energy and amplified to traveling-wave field, electromagnetic wave signal.Leave high-frequency electrical
The electronics note of field still includes sizable energy, continues to reclaim this part component using depressed collector, to improve travelling-wave tubes
Efficiency.And remaining electron energy is converted into heat energy in collector, and by interior collector, insulating porcelain piece and outer collector
It is transmitted to outside pipe.
Fig. 1 show the diagrammatic cross-section of existing collecting pole structure, and it is symmetric form wherein to be received in collector, and it includes interior
The ˊ of electron injection mouth 4 on the ˊ of collector 1, the ˊ of outer collector 3 and insulating porcelain piece 2 ˊ, the interior ˊ of collector 1 is set in horizontal mouth, and the electricity
The sub- ˊ of inlet 4 penetrates direction perpendicular to electron injection and set.Fig. 2 show existing collector and welded with being covered on bottom plate and collector
The ˊ of bottom 5 of profile afterwards, wherein collector is used to closely weld with the ˊ of bottom plate 7, and the ˊ of the collector first half 6 is used for and collector
The upper ˊ of lid 8 is closely welded.
Fig. 3 show equipotential surface and electron trajectory schematic diagram for existing collector, wherein with A point-like electron and B points electricity
Son illustrates existing collector trajectory of electron motion, and in Fig. 3,1 notes approach axis to for electronics, and 2 enter electrode fortune to for A point-like electron
Dynamic direction, 3 to for A point-like electron direction of motion equipotential line radial components, and 4 to for A point-like electron direction of motion equipotential line tangential components,
5 note Impact direction to for A point-like electron, and 6 enter electrode movement direction to for B point-like electron, and 7 to for B point-like electron Impact directions.

On collector bottom.Using B point-like electron as line of demarcation, the electronics in left side is beaten to be beaten on right side in left side, the electronics on right side.Due to electricity
The symmetry of son note and collector, the quantity that electronics is beaten in collector all directions is substantially impartial, and collector is respectively to caused
Heat is also impartial, therefore the quantity that electronics is beaten in the interior ˊ all directions of collector 1 is substantially impartial, due in use, collector
The ˊ of bottom 5 is used to closely weld with bottom plate, and a part of heat energy in collector is directly conducted to bottom plate and radiated, and another portion
Point heat energy by being transmitted to the ˊ of lower half 5 of collector, then is conducted to bottom plate and radiated by the ˊ of the collector first half 6, collector
On heat consumption it is bigger, the ˊ of top 6 of collector and the ˊ of bottom 5 of the collector temperature difference are bigger, in turn result in up and down radiating it is uneven.
Therefore, it is necessary to design one kind on the premise of electrical property is not changed, the electric current that collector is collected can be made more to beat
Close to bottom plate position, the collector of collector radiating effect can be greatly improved.
