Fig. 2 is a kind of water-cooled magnetron of the utility model water jacket main structure chart;
Fig. 3 is a kind of water-cooled magnetron of the utility model water jacket taper sheath three-dimensional structure diagram.
Below in conjunction with accompanying drawing, the utility model is further described.
See Fig. 1-Fig. 3, the embodiment of a kind of water-cooled magnetron of the utility model water jacket, comprise water jacket main body 1, described water jacket main body 1 is provided with installing hole 2 and water channel 3, described water channel 3 is around being arranged at around described installing hole 2, the end of described water jacket main body 1 is provided with water inlet 11 and delivery port 12, described water channel 3 is communicated with described delivery port 12 with described water inlet 11 respectively, also comprise the taper sheath 4 for being set with vacuum tube, the medial surface of described installing hole 2 is the taper surface coordinated with described taper sheath 4, and described water jacket main body 1 is set on described taper sheath 4.
Specifically, magnetron in the present embodiment mainly utilizes the mode of water-cooled to dispel the heat, the vacuum tube easily raising damage to temperature in magnetron carries out the heat loss through conduction of heat, mainly carry out heat conducting mode by water jacket main body 1 and vacuum tube to carry out, water jacket main body 1 inside is provided with the water channel 3 of circulation, and offer installing hole 2 at the center position of water jacket main body 1, water channel 3 integral loop is arranged around installing hole 2, installing hole 2 mainly carries out installation with vacuum tube and coordinates, can to be taken away by a part of heat of its inside by the cooling water that is looped around the water channel 3 around it when temperature in vacuum tube is very high like this makes its temperature reduce, reach the object of heat radiation.The concrete structure of water jacket main body 1 can be U-shaped, also can be annular, not do concrete restriction at this.Specifically when installing cooperation, vacuum tube is installed fixing by a taper sheath 4 and water jacket main body 1, taper sheath 4 is first set on vacuum tube, then water jacket main body 1 is set on taper sheath 4 and realizes being mounted with of three, for matching when realizing sheathed with taper sheath 4, the inner side installing hole 2 of water jacket main body 1 is designed to taper surface, can realize like this closely cooperating when being set-located.
Taper sheath 4 structure and vacuum tube is adopted to fix, fix sheathed to the tapered inner side surfaces of water jacket main body 1 and taper sheath 4 more simultaneously, namely the accuracy of assembling and heat conducting rapidity can be guaranteed, for convenience detach again, because it coordinates for pyramidal structure, only need to overcome the coordinate force existed between bullet a little can easily whole taper sheath 4 and vacuum tube be extracted out in the lump, water jacket main body 1 structure can not be corrupted to, even if vacuum tube and taper sheath 4 are damaged, water jacket main body 1 also can continue to use, achieve the recycling of water jacket main body 4, improve utilance, reduce production cost,
Specifically, taper sheath 4 version in the present embodiment can have multiple different structure, a kind of version is: taper sheath 4 is the conical shell of constant wall thickness, the tapering of conical shell is 1:14-1:16, wall thickness is 2-3mm, corresponding conical shell medial surface is taper surface with lateral surface and tapering change direction is consistent, is steady state value wall thickness.
Certainly, taper sheath 4 also can select the wedge shape housing of wall thickness change, wedge shape housing wall thickness reduces from the large end of external diameter successively to external diameter small end, the medial surface of the taper sheath 4 of its correspondence is taper surface, lateral surface is also taper surface, but in it, the tapering of lateral surface is different, and the thickness of its correspondence is also gradually changing.
In addition, wedge shape enclosure interior can be the constant through hole in aperture, and wedge shape hull outside face is the conical surface, and the tapering of the conical surface is 1:14-1:16, and the medial surface of correspondence is then the constant circular face in aperture, can realize equally coordinating with the installation of installing hole 2 and vacuum tube.
For realizing closely cooperating of water jacket main body 1 and taper sheath 4, should guarantee that installing hole 2 medial surface tapering is identical with taper sheath 4 lateral surface tapering, the Matching installation of both realizations.
Further, the circulation realizing current is identical with force value, and water inlet 11 is in the same plane with the upper surface of delivery port 12.
In the present embodiment for the tapering selected value of taper sheath 4 all between 1:14-1:16, because suitable tapering can guarantee that taper sheath 4 coordinates with vacuum tube closely, be convenient to the conduction of heat, and the thickness of described taper sheath 4 is generally chosen between 2-3mm, thinner thickness can be guaranteed taper sheath 4 and carry out heat transmission fast between vacuum tube and water jacket main body 1, reach good heat-conducting effect, for material, taper sheath 4 material can aluminium, thinner thickness good heat-transfer, adopt aluminum component ductility good, can the requirement of adaptive deformation.
