Background technology
High power magnetron is more and more extensive in the application of each side such as modern industry, medical treatment, to the working life of magnetron, job stability with require also more and more higher to the adaptability of environment。At present, the cooled cathode of high power magnetron mainly adopts natural radiation to dispel the heat, it does not have does corresponding Cooling Design for cooled cathode, therefore there is problems in that
One, high power magnetron cathode internal temperature is too high, easy scaling loss, reduces magnetron life；
Two, the negative electrode of rate magnetron has ceramic package, and heat radiation is slow；
Three, cooled cathode is by natural radiation heat radiation, and the heat given out all is stayed in equipment, affects whole service life of structure；
Four, when ambient temperature is too high, magnetron work efficiency drop, environmental suitability is poor。
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, a kind of high power magnetron cathode cooling device is provided, cooling air is adopted to cool down, get up to be discharged into outside equipment by the heat collection that magnetron produces, reach good cooling effect, improve the working life of high power magnetron and the adaptability to environment。
It is an object of the invention to be achieved through the following technical solutions: a kind of high power magnetron cathode cooling device, including the first cooling dome assembly and the second cooling dome assembly, described first cooling dome assembly and the second cooling dome assembly are mutually adjacent to and fix, with the first semicircle jack on first cooling dome assembly, second cooling dome assembly is inserted with the second semicircle, with seal groove on first semicircle jack and the second semicircle jack, first cooling dome assembly, outside second cooling dome assembly and magnetron, common encirclement forms cooling work space, it also includes cooling air air inlet, warm braw return air inlet, cooling air fresh air inlet, cooling air chamber and warm braw groove, described cooling air air inlet and warm braw return air inlet are arranged on the first cooling dome assembly and the second cooling dome assembly, cooling air air inlet connects with cooling air chamber, outer wall in cooling air chamber has cooling air fresh air inlet, warm braw return air inlet connects with warm braw groove。
The two ends of described first cooling dome assembly and the second cooling dome assembly are provided with installing hole。
Described warm braw return air inlet is arranged on first and second cooling dome assembly with cooling air air inlet for the position of the axis of symmetry, and is circumscribed with backwind tube。
The invention has the beneficial effects as follows: a kind of high power magnetron cathode cooling device, cooling air is adopted to cool down, get up to be discharged into outside equipment by the heat collection that magnetron produces, reach good cooling effect, improve the working life of high power magnetron and the adaptability to environment。

Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is described in further detail, but protection scope of the present invention is not limited to the following stated。
As shown in Figure 1, a kind of high power magnetron cathode cooling device, including the first cooling dome assembly 1 and the second cooling dome assembly 2, described first cooling dome assembly) and the second cooling dome assembly 2 be mutually adjacent to and fix, with the first semicircle jack 6 on first cooling dome assembly 1, with the second semicircle jack 3 on second cooling dome assembly 2, with seal groove 8 on first semicircle jack 6 and the second semicircle jack 3, jointly surround by first cooling dome assembly the 1, second cooling dome assembly 2 after sealing mechanism with outside magnetron and form cooling work space。
As shown in Figure 2, it also includes cooling air air inlet 5, warm braw return air inlet 4, cooling air fresh air inlet 7, cooling air chamber 9 and warm braw groove 11, described cooling air air inlet 5 and warm braw return air inlet 4 are arranged on the first cooling dome assembly 1 and the second cooling dome assembly 2, cooling air air inlet 5 connects with cooling air chamber 9, outer wall in cooling air chamber 9 has cooling air fresh air inlet 7, and warm braw return air inlet 4 connects with warm braw groove 11。The two ends of the first cooling dome assembly 1 and the second cooling dome assembly 2 are provided with installing hole 10。
Described warm braw return air inlet 4 is arranged on first and second cooling dome assembly with cooling air air inlet 5 for the position of the axis of symmetry, and is circumscribed with backwind tube。
The operation principle of the present invention is as follows: as shown in Figure 1 and Figure 2, also has installing hole 10 at the two ends of the first cooling dome assembly 1 and the second two cooling dome assemblies 2。Seal groove 8 on the first semicircle jack 6 and the second semicircle jack 3 loads onto sealing mechanism, on the first cooling dome assembly 1 on the mouth of pipe of the warm braw return air inlet 4 on warm braw return air inlet 4 and the second two cooling dome assemblies 2 basis upwards, installing hole 10 on first cooling dome assembly 1 and the second two cooling dome assembly 2 installing holes 10 are directed at, and the first cooling dome assembly 1 and the second two the cooling dome assembly 2 two sides with installing hole are adjacent to alignment, fixing screw, through installing hole, uses nut fix in position。Cooling air air inlet 5 at the first cooling dome assembly 1 and the second cooling dome assembly 2 connects cooling air, and cooling air enters into cooling air chamber 9 by cooling air air inlet 5, then sprays from cooling air fresh air inlet 7, beats and cools down in the outside of magnetron cathode。Warm braw after cooling enters warm braw groove 11, then passes through the warm braw return air inlet 4 connected on warm braw groove 11 and connects backwind tube by outside warm braw device for transferring。The cooled cathode of such high power magnetron is cooled down by chiller cooling air, the working life of high power magnetron can be improved, can also get up to be discharged into outside equipment by the heat collection that magnetron produces, improve the working life of whole equipment, it is also possible to improve the adaptability to environment。
