Description
Technical field
The utility model relates to detecting instrument field, specifically, relates to a kind of X-ray tube heat abstractor for detecting instrument.
Background technology
The X-ray that analyzed sample sends under x-ray bombardment, comprises the information of analyzed sample chemical composition, and by determining that the instrument of each component content in sample is exactly x-ray fluorescence analyzer to the analysis of above-mentioned XRF.
In x-ray fluorescence analyzer, the caloric value of X-ray tube is very big, and distribute if heat cannot obtain, then will cause great injury to X-ray tube, therefore X-ray tube must be furnished with heat abstractor; The radiator structure of current X-ray tube is mainly directly blown by fan, or will disperse wind convergence by ventilating duct directly blows to light pipe, the same like this X-ray tube that can cause burns out light pipe because not left in time by the heat of wind direction, so, then cause the significantly rising of waste and cost greatly, therefore, in the urgent need to finding one heat abstractor more effectively.
Utility model content
In view of this, need to overcome at least one in above-mentioned defect of the prior art.The utility model provides a kind of X-ray tube heat abstractor, comprising:
X-ray tube;
Cylindric ventilating duct, described X-ray tube is arranged on described ventilating duct center, and described X-ray tube axis overlaps with described ventilating duct axis;
Thermal component, described thermal component is that annular flat part is formed, and be arranged between described X-ray tube and described ventilating duct, described thermal component is thermal conductive metal plate, and described thermal component is with fold shape region;
Air inlet, described air inlet is arranged on the bottom of described ventilating duct;
Wind force device, described wind force device and described air inlet are connected.
According in the utility model background technology to described in prior art, in X fluorescence spectrum is analyzed, X-ray tube, for generation of simple X-ray, usually applies the high pressure of tens kilovolts, in this process, produces very big heat to it, the too high meeting of X-ray tube temperature has an impact to light pipe stability and life-span, therefore need to dispel the heat to it, the utility model discloses a kind of light pipe heat abstractor, by increasing area of dissipation, by rapid air movement, light pipe temperature is made to be reduced to room temperature fast.
In addition, disclosed in the utility model, X-ray tube heat abstractor also has following additional technical feature:
Further, described thermal conductive metal plate is copper sheet or aluminium flake.
Further, described thermal component has undulating pleats region.
Preferably, the crest/trough quantity of described undulating pleats region formation is between 10 to 25.
The cross section of undaform can increase the area of dissipation of thermal component further, and when the quantity of Wave crest and wave trough is between 10-25, radiating efficiency is enough high, also can avoid enough large noise simultaneously.
Further, described cylindric ventilating duct inner circle radius is Rb, and described thermal component inscribed circle radius is Ra, and described thermal component arc radius that Wave crest and wave trough is formed is r, then meet 2.5mm≤Rb-Ra-r≤5mm and Ra is 8 to 15 times of r.
Further, also heat-conducting medium is comprised between described X-ray tube and thermal component.
Heat-conducting medium between X-ray tube and thermal component, plays the effect of support X ray pipe on the one hand, can increase area of dissipation and the heat transfer efficiency of X-ray tube on the other hand further.
Further, described wind force device is air blast.
