Description
Technical field
The invention belongs to medical detections and ray to measure detection technique field, in particular to a kind of ripple ceramic structure is medical
X-ray tube.
Background technique
X-ray tube is mainly used on the Medical Devices such as X-ray production apparatus, CT machine, in the case where applying external high pressure effect, generates X and penetrates
Line is diagnosed or is treated to patient for doctor.
X-ray tube generate X-ray mechanism approximately as：The filament of X-ray tube（Cathode）In a heated state, freely
Electronics escapes filament surface, forms electron cloud.Apply under high-voltage case between X-ray tube cathode, anode（Generally 40 ~ 150
Kilovolt）, the electronics high speed at filament flies to target disc（Anode）, X-ray is generated after hitting anode disc, and defeated by ray window
Effective X-ray out.In this energy conversion process, only 1% electronic kinetic energy is converted into X-ray, and the kinetic energy of residue 99% is whole
It is converted into thermal energy, by heat radiation or heat transfer, is reached outside X-ray tube, is taken away by X-ray pipe sleeve and X-ray tube radiator.Tool
For body, including：（1）The heat of target disc（Account for the 90% of total amount of heat）A part is radiated on the metal-back in the middle part of X-ray tube, separately
A part is radiated outside X-ray tube through both ends glass bulb, and last part is taken away by rotor copper sheathing.It is radiated gold among these
The heat maximum for belonging to shell accounts for about 60%, through the heat about 20% of glass radiation, the heat about 20% taken away by rotor copper sheathing.（2）
The heat of cathode（Account for total amount of heat 10%）It is taken away by cathode glass and metal-back.Therefore, the thermal management of X-ray tube is to influence
One of its reliability and the key factor in service life.
Currently, Conventional X-ray tubes mainly use glass insulation structure, general structure is：（1）Cathode glass-intermetallic metal-
Anode glass structure；（2）Whole glass-cathodic metal-anode metal structure.Existing X-ray tube is illustrated in figure 4 using glass
Glass insulation system.
Conventional X-ray tubes mainly use glass insulation structure, since the intensity and stress of glass limit, glass knot
Structure is not suitable for big thermal capacity X-ray tube.
Its major defect is：
1, glass insulation characteristic is limited to：Especially anode glass bulb has 20% target disc heat to be radiated X-ray tube by glass
Outside, since the softening temperature of glass is low（Only 550 DEG C）, and there are the critical defects of TK100 value, when heat is excessively concentrated
It is easy to produce electric discharge phenomena.（Note：TK100 refers to that dielectric strength declines rapidly when glass reaches some temperature spot, and general X is penetrated
The glass TK100 value of spool is 300 degree or so）；
2, glass sealing position mechanical strength is low：Since anode glass bulb carries the weight of target disc and bearing, the carrying of cathode glass bulb
The weight of cathode taps and stem, and glass can only be by guarantee glass by hand and can cut down coaxial during sealing-in
Degree leads to that stress will necessarily be generated in welding, when glass can be cracked or be fried a little under certain heat condition；
3, complex process, many places weld seam：There is a weld seam at 3 at cathode position as seen from Figure 4, and more one of weld seam are with regard to more one of gas leakage
Possibility.In order to avoid gas leakage, increase the reliability that necessary processing step guarantees weld seam, so as to cause complex process.
