Rate place.
Description of the drawings
Fig. 1 is the structural schematic diagram for the waveguide adjustable attenuator that the embodiment of the present invention proposes.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, the embodiment of the present invention proposes a kind of waveguide adjustable attenuator, including rectangular wave conductor 1；
The broadside center of the rectangular wave conductor 1 offers sipes seam 2, and the both sides of the sipes seam 2 are arranged in parallel with gold
Belong to piece 3, container 4 is provided in the sipes seam 3；
Decaying liquid, the container are provided with liquid outlet and inlet in the container 4, the rectangular wave conductor exists
Position corresponding with the liquid outlet and inlet is provided with the liquid outlet connector being connect with circulating cooling system 5 and inlet connects
Head, the liquid outlet connector and the inlet connector are respectively turned on the liquid outlet and the inlet；
The circulating cooling system 5 includes decaying liquid case 501, and the decaying liquid case 501 is connect with 4 bottom of the container,
Interconnecting piece is provided with constant flow rate valve 502.
As it can be seen that the waveguide adjustable attenuator that the embodiment of the present invention proposes, by the way that the decaying liquid connection cycle in container is cold
But system is radiated by the way that the decaying liquid in container is continued through circulating cooling system, so as to improve heat dissipation effect,
Suitable for high-power place.
In a preferred embodiment of the invention, the container is polyfluortetraethylene plate.
Polyfluortetraethylene plate (being also tetrafluoro plate, Teflon plate, Teflon plate) be divided to molding and two kinds of turning, moulded board be by
Polyflon is molded with die pressing at normal temperatures, then is made through sintering, cooling.PTFE lathed plates are by poly- four
Fluoroethylene resin is formed through green compact, sintering, rotary-cut.Its product-use is wide, has extremely superior comprehensive performance：High-low temperature resistant (-
192 DEG C -260 DEG C), corrosion-resistant (strong acid, highly basic, chloroazotic acid etc.), weatherability, high insulation, it is high lubricate, do not adhere to, nonhazardous etc. it is excellent
Good characteristic.
When container is polyfluortetraethylene plate, it can be passed through different decaying liquid as needed without replacing container.
In a preferred embodiment of the invention, the circulating cooling system includes the first connecting tube, the second connecting tube
