Technical field
The invention belongs to microwave magnetron technical field, specifically a kind of water cooled magnetron.
Background technology
Microwave magnetron is a kind of electron tube for producing microwave energy.A substantially diode being placed in stationary magnetic field, in pipe, electronics is under the control of orthogonal stationary magnetic field and steady electric field, interact with electromagnetic field of high frequency, become microwave energy obtaining energy conversion from steady electric field, thus reach to produce the purpose of microwave energy.Common magnetron structures mainly includes that support, vacuum tube, Magnet, mounting base, filtering unit, shielding be box-packed and water jacket；Wherein water jacket is provided with a water inlet and an outlet.Because magnetron is operated under high frequency environment, and power is higher, and vacuum tube easily generates heat, and general in actual use employing is air-cooled or water-cooling pattern dispels the heat.And in commercial Application, magnetron is chronically at duty, the most industrial magnetron many employings water cooled magnetron, heat radiating water jacket and vacuum tube physical contact, water jacket is transferred heat to by heat exchange pattern, water jacket heat is persistently taken away by the recirculated water in water jacket, thus ensures that vacuum tube temperature will not cause work continuously persistently to raise, and magnetron is finally operated in a stable state.
Existing common water-cooled magnetron, its structure includes support, is provided with vacuum tube in support, and Magnet is sleeved on vacuum tube two ends, and one end of support is provided with fixing base plate, filtering unit and shielding box and is installed in the other end of support；The outer sheath of described vacuum tube, equipped with cooling jacket, cooling jacket is provided with cooling water intake and outlet, is mainly dispelled the heat by water circulation, conduction of heat.
Mainly being dispelled the heat by the contact of cooling jacket and central canal owing to water cooled magnetron design is upper, therefore water jacket and the processing of central canal and assembly precision directly determine the quality of radiating effect；And the stable output of good heat radiation guarantee microwave magnetron.
Existing water jacket uses the mode of parallel assembling with vacuum tube, and machining accuracy will directly affect the quality of heat radiation, and assembling capacity is poor during assembling, assemble tension, can cause central canal resonator cavity deformation, affects microwave magnetron output；Assembling pine, heat radiation can be caused bad, magnetron life reduces.Ordinary circumstance is to ensure that magnetron has good heat radiation, require it is all by the tightst for the assembling of vacuum tube and water jacket, but it is susceptible to damage when thus causing water jacket dismounting, water jacket recovery difficult is bigger, in water cooled magnetron cost, cooling jacket cost accounting is higher, and high-volume causes the wasting of resources and cost of equipment maintenance to increase when using.
Summary of the invention
The technical problem to be solved is: propose a kind of water cooled magnetron, the problem solving to cause water jacket and vacuum tube assembling capacity difference because machining accuracy is low, both can guarantee that radiating effect, and the assembly and disassembly of water jacket and vacuum tube can have been realized again neatly, improve the recovery utilization rate of water jacket.
It is an object of the invention to be achieved through the following technical solutions:
A kind of water cooled magnetron, including cooling jacket, central canal, installing hole and water channel it is provided with on described cooling jacket, it it is resonator cavity in the middle part of described central canal, it is characterized in: in the middle part of described central canal, resonator cavity lateral surface is cone, the installing hole of described cooling jacket be with described central canal in the middle part of the round taper hole that coincide of conical outside face, described central canal inserts described installing hole and described cooling jacket and realizes assembling.
Further, in the middle part of described central canal, the external diameter of the conical upper end of resonator cavity is more than the external diameter of its lower end.
