Abstract
The utility model discloses a slow-wave heat radiation structure of a travelling wave tube, relating to the microwave electric vacuum member filed. The slow-wave heat radiation structure of the travelling wave tube comprises a travelling wave tube slow wave tube and a heat radiation bottom; and melted heat radiation alloy fills the gap between the travelling wave tube slow wave tube and the heat radiation bottom plate. Compared with the prior art, the slow wave tube is fast in heat conduction and is beneficial for transmitting the heat on the slow wave tube out and dissipating.
Description
Technical field
The utility model relates to a kind of structure of microwave electron tube, relates in particular to a kind of slow wave radiator structure of travelling wave tube.
Background technology
Travelling wave tube is a kind of microwave electrovacuum power device, mainly in microwave signal system, play final stage amplification, application is extensive, travelling wave tube has frequently the large and low feature of noise of high ﹑ dynamic range that gains with wide ﹑, has become Lei Da ﹑ electricity and the logical letter ﹑ that continues in anti-﹑ is defended to the logical letter of star ﹑ live telecast has defended the important microwave electronic device that star ﹑ leads the electronic equipments such as the distant ﹑ of control of boat ﹑ distant sense ﹑ remote measurement.During travelling wave tube work, slow wave part at travelling wave tube is intercepted and captured heat-dissipating because a small amount of irregular electrons produces, if this part heat can not effectively spread out of dissipation, thereby can have a negative impact and affect the job stability of travelling wave tube the operational environment of travelling wave tube, when serious, also can damage travelling wave tube, therefore, solution TWT slow wave heat dissipation problem is extremely important.
Utility model content
The utility model provides a kind of TWT slow wave radiator structure, the heat producing effectively can be spread out of to dissipation in the TWT slow wave course of work, to reach, guarantees that travelling wave tube is working properly, stable and reliable.The technical solution of the utility model is: a kind of TWT slow wave radiator structure, comprise TWT slow wave, radiating bottom plate, the liquidus temperature that is filled with the alloy that dispels the heat described in the heat radiation alloy after thawing in the gap of described TWT slow wave and radiating bottom plate lower than travelling wave tube in permanent magnetic material magnetic property can reversible variation maximum temperature.。
Described TWT slow wave radiator structure, described heat radiation alloy is SnAg alloy.
Described TWT slow wave radiator structure, the fusing point that described heat radiation alloy is SnAg alloy is less than 280 ℃.
Described TWT slow wave radiator structure, described heat radiation alloy can also be scolding tin.
Adopt TWT slow wave radiator structure described in the utility model, compare with original technology, slow wave heat conduction velocity is faster, the heat by slow wave that can be more favourable spreads out of dissipation, on certain type travelling wave tube, adopt the working temperature of the travelling wave tube of this kind of slow wave radiator structure on original basis, to reduce by 15 ℃.
Accompanying drawing explanation
A kind of TWT slow wave radiator structure schematic diagram described in Fig. 1 the utility model specific embodiment;
1-radiating bottom plate in Fig. 1,2-heat radiation alloy SnAg alloy, 3-TWT slow wave.
Embodiment
Now in conjunction with accompanying drawing of the present utility model; technical scheme in the utility model embodiment is known intactly and described; obviously; described embodiment is only a part of embodiment of the present utility model; rather than whole embodiment, the embodiment based in the utility model, those of ordinary skills are not making under creative work prerequisite; the every other embodiment obtaining, belongs to protection range of the present utility model.
Embodiment mono-
A kind of TWT slow wave radiator structure, comprise TWT slow wave, radiating bottom plate, in the gap of described TWT slow wave and radiating bottom plate, be filled with the heat radiation alloy after thawing, the alloy that dispels the heat described in the present embodiment is SnAg alloy, the fusing point that described heat radiation alloy is SnAg alloy is less than 280 ℃, the maximum temperature that the liquidus temperature of heat radiation alloy SnAg alloy described here can reversible variation lower than permanent magnetic material magnetic property in travelling wave tube.
TWT slow wave radiator structure described in employing the present embodiment, owing to need slow wave heat radiation being used to said structure, compared with prior art, slow wave heat conduction velocity is faster, the heat by slow wave that can be more favourable spreads out of dissipation, on certain type travelling wave tube, slow wave temperature is compared on the temperature basis of heat sink clip block mode of existing use and has reduced by 15 ℃.
