Abstract
The utility model discloses a travelling wave tube collector, which comprises a tube shell, wherein a collector inner barrel is arranged in the tube shell, ceramic balls are arranged between the tube shell and the collector inner barrel, and fluorocarbon liquid is filled in gaps among the ceramic balls. In the traveling wave tube collector, the ceramics can be prevented from being cracked, and excellent heat-conducting property is obtained.
Description
Technical field
The utility model relates to the travelling wave tube field, and especially the travelling wave tube collector is specially a kind of travelling wave tube collector.
Background technology
Travelling wave tube is the power amplifying device that a kind of kinetic energy that utilizes high-velocity electrons to annotate and with the microwave signal mutual effect electronics is annotated is converted into microwave energy.The range of application of travelling wave tube is very wide, and nearly all satellite communication all uses travelling wave tube as final amplifier.In most of radar systems, all to use one or some travelling wave tube as the high power amplifier that produces the high-frequency emission pulse.In addition, travelling wave tube can also be used in some high power amplifier in miscellaneous equipment, as the drive(r) stage of crossed field amplifier.Though proposed the travelling wave tube high-frequency circuit topology of many types, mainly have only two classes, promptly at the helix of broadband occasion use and the coupling cavity that uses in large-power occasions.
No matter be coupled-cavity TWT or helix TWT, all form by electron gun, slow wave system, magnetic focusing system, input-output system, these five vitals of collector.Wherein, collector is the electronics that reclaims after the mutual effect, and the dump energy of the electronics mode by heat energy is dissipated away.The heat of travelling wave tube more than 70% all produces on collector and dissipates, so the design of collector and the design made for travelling wave tube are very crucial.
General collector all needs the step-down practicality, and its voltage will be lower than the voltage of slow wave system, so collector will insulate with slow wave system, also will with the shell insulation of ground connection.In the design of popwer travelling wave tube collector, generally between the inner core of collector and shell, insulate by the welding ceramics tube.Because pottery differs bigger with the expansion absorption of metal, cause the cracking of pottery easily, and finally cause scrapping of travelling wave tube.
The utility model content
The purpose of this utility model provides a kind of travelling wave tube collector, to solve the problem easy to crack when being heated of the pottery between the collector inner core and shell in the popwer travelling wave tube.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of travelling wave tube collector, include shell, an end is equipped with the insulating ceramics of end cap shape in the described shell, the shell other end is equipped with the end cap of band pin, also be provided with the collector inner core in the described shell, described collector inner core one end embeds in the insulating ceramics, and the other end is electrically connected with described pin, it is characterized in that: be filled with the Ceramic Balls of a plurality of heat conduction between the collector inner core in described shell and the shell, the space between the described Ceramic Balls is filled with fluorocarbons liquid.
The utility model utilizes the cylindric space that forms between collector inner core and the shell, places the Ceramic Balls of the less heat conduction of volume in the space, and with the space between the fluorocarbons liquid filling Ceramic Balls.So promptly can prevent the pottery cracking, can obtain good heat conductivility again.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1.A kind of travelling wave tube collector, include shell 1, an end is equipped with the insulating ceramics 4 of end cap shape in the shell 1, shell 1 other end is equipped with the end cap 3 of band pin 5, also be provided with collector inner core 2 in the shell 1, collector inner core 2 one ends embed in the insulating ceramics 4, and the other end is electrically connected with pin 5, be filled with the Ceramic Balls 6 of a plurality of heat conduction between the collector inner core 2 in shell 1 and the shell 1, the space between the Ceramic Balls 6 is filled with fluorocarbons liquid.
At first collector inner core 2 and shell 1 and insulation porcelain 4 are welded.This moment, insulation porcelain 4 was not subjected to the effect of radial load, axially can freely stretch, so insulation porcelain did not have the danger of cracking.In the good parts of above-mentioned welding, formed a space cylindraceous, populated Ceramic Balls 6 in this space, the material of Ceramic Balls can be beryllium oxide.After populated Ceramic Balls, a spot of fluorocarbons liquid is poured in the cylinder space, make the gap between the good Ceramic Balls of liquid filling.End cap 3 and pin 5 are welded.The assembly that welding is good covers the cylinder of having filled Ceramic Balls and fluorocarbons liquid by shown in Figure 1, and carries out argon arc welding and connect.So novel travelling wave tube collector described in the utility model just completes.
