Abstract
Description
Technical Field
[0001] The utility model belongs to the field of high-energy ray emitting devices, in particular to a ray emitting device and an X-ray machine and an industrial detector having the same. Background Art
[0002] Most of the existing X-ray machines or industrial detectors generate X-rays through a ray emitting device with a vacuum tube, and emit the X-rays in the detection direction. The principle of the vacuum tube to generate X-rays is that the high-speed electrons emitted from the cathode end collide with the metal target at the anode end to generate X-rays. In this process, since the high-speed electrons that generate X-rays will generate a lot of heat when they collide with the metal target at the anode end, in order to avoid the generated heat burning the ray emitting device, a vacuum tube is required to dissipate heat. In the existing heat dissipation device, the entire tube is usually immersed in the coolant, so that the heat generated by the collision with the metal target escapes into the coolant. However, the heat dissipation efficiency of this design will decrease as the temperature of the coolant increases, and the application scenarios of such ray emitting devices usually require a small footprint (hospital), easy disassembly and movement (industrial detection). These scenarios usually do not have the conditions to replace the coolant, so the heat dissipation efficiency cannot be improved by circulating and replacing the coolant. Utility Model Content

[0031] The ray emitting device provided by the utility model immerses the cathode end of the bulb in the coolant, exposes the anode end of the bulb and one end of the target inside the bulb to the air outside the refrigeration box, and dissipates the heat of the bulb and the one end of the target exposed to the air through the heat dissipation device, so that the heat generated in the bulb can be quickly dissipated from the anode end at the same time, and only a small part of the heat escapes into the coolant, which has a higher heat dissipation efficiency than a heat dissipation device that only uses the coolant. When the temperature of the coolant rises, the temperature of the coolant can also be lowered by dissipating the heat of the bulb and the one end of the target exposed to the air, without the need to replace the coolant.
[0032] The concepts involved in the embodiments of the present invention are described below:
[0033] Peltier effect: refers to the thermoelectric effect produced by passing electricity between two different types of semiconductor materials.
[0034] The specific device of the embodiment of the utility model is described below in conjunction with the accompanying drawings.
[0035] Reference Figure 1 to Figure 3 , Figure 1 The front view of the ray emitting device of the embodiment of the utility model, the ray emitting device specifically includes: a refrigeration box 100, a bulb 200, a heat dissipation device, a temperature sensor 600, a power supply module and a control module; wherein the interior of the refrigeration box 100 is filled with a coolant, the refrigeration box 100 is provided with a first opening 110 and a second opening, and the first opening 110 is provided with a closed window 111 for sealing the first opening 110 and for passing the ray; the cathode end 210 of the bulb 200 is arranged inside the refrigeration box 100 and immersed in the coolant The anode end 220 of the bulb 200 is passed through the second opening from the inside of the refrigerator 100, and the anode end 220 is exposed outside the refrigerator 100. A target is arranged inside the bulb 200 on one side of the anode end 220. The first end of the target is arranged inside the bulb 200, and the second end 221 of the target is exposed outside the bulb 200 and the refrigerator 100. The heat dissipation device includes an anode connection block 310 and a heat dissipation mechanism 320. The anode connection block 310 is covered on the second end 221 of the target, and the heat dissipation mechanism 320 is attached to the anode connection block 310.
[0036] The coolant filled in the refrigerator 100 may be a refrigeration oil formed by a mixture of various organic compounds, or water with an anti-corrosion agent added, or a fluid medium that can be used for cooling, and the utility model does not impose any restrictions on this. In order to improve the efficiency of generating X-rays in the bulb tube 200, the inside of the bulb tube 200 may be evacuated into a vacuum environment; the cathode end 210 in the bulb tube 200 is electrically connected to the power supply module, and the power supply module provides high-voltage electricity to heat the cathode end 210, so that the cathode end 210 emits high-speed electrons to the anode end 220, and the cathode end 210 may use a tungsten wire made of metal tungsten as the material for emitting electrons; the target is set at the anode end 220 in the bulb tube 200, and a tungsten block made of metal tungsten may be used as a target to withstand the bombardment of high-speed electrons to generate X-rays; the emission direction of the X-rays depends specifically on the setting positions of the tungsten wire and the tungsten block, and may be set to be emitted from the target through the first opening 110 and the closed window 111, and the first opening 110 and the closed window 111 refer to Figure 2 , the structure corresponding to the ball tube is referenced Figure 3 , Figure 5 . Further, the end of the target subjected to high-speed electron bombardment is regarded as the first end of the target in the embodiment of the utility model, and the part exposed to the outside of the refrigeration box 100 and the outside air is regarded as the second end 221 of the target. The second end 221 of the target is completely covered by the anode connection block 310 made of a material with good thermal conductivity. The purpose of such design is to ensure that the heat of the second end 221 of the target can be quickly transferred to the anode connection block 310 with a larger surface area, thereby improving the heat dissipation efficiency. Finally, the anode connection block 310 is cooled by the heat dissipation mechanism 320. Such a setting greatly improves the heat dissipation efficiency of the entire ray emitting device, and there is no need to replace the coolant in the refrigeration box 100.
[0037] like Figure 1 As shown, in this example, the heat dissipation mechanism 320 includes a fin heat sink 321 and a first fan 322; the side of the fin heat sink 321 without fins is attached to the anode connection block 310, and the side of the fin heat sink 321 with fins is attached to the first fan 322. Specifically, the type of fins of the fin heat sink 321 can be straight fins, curved fins, wedge-shaped fins, etc., which can be selected according to the required heat dissipation effect, and the utility model does not limit this. The fin heat sink 321 is attached to the anode connection block 310 and is made of a heat-conducting material, which can conduct the heat transferred by the target to the fins. The side of the fin heat sink 321 with fins continuously blows air to the fins through the first fan 322 to achieve heat dissipation.
[0038] like Figure 4 , Figure 5As shown, in this example, the heat dissipation mechanism 320 also includes a water-cooled radiator 323, a water tank 325, a water pump and a second fan 324; a heat-conducting structure is provided on the water tank 325, one side of the heat-conducting structure is attached to the anode connecting block 310, and the other side of the heat-conducting structure is in contact with the cold circulating water inside the water tank 325; the water tank 325 is connected to the water-cooled radiator 323 through a pipeline; the water pump is used to pump the cold circulating water into the water-cooled radiator 323 through the pipeline and to return the cold circulating water in the water-cooled radiator 323 to the water tank 325 through the pipeline; the second fan 324 is attached to the water-cooled radiator 323. Specifically, in addition to the fin-type radiator provided in the above-mentioned embodiment, the heat dissipation mechanism 320 can also use the water-cooled radiator provided in this example. This type of radiator attaches a water tank 325 made of heat-conducting material to the anode connection block 310, so that the heat dissipated from the bulb 200 is conducted to the cold circulating water in the water tank 325 through the anode connection block 310, and then the cold circulating water that absorbs the heat dissipation is continuously input into the direct water-cooled radiator 323 through a water pump, and the heat is dissipated through the second fan 324, and the cooled cold circulating water is returned to the water tank 325 to achieve continuous heat dissipation.
[0039] In this example, the heat dissipation mechanism 320 further includes a water cooling controller, which is electrically connected to the control module; the water cooling controller is used to control the water pump to pump the cold circulating water into the water cooling radiator 323 or to return the cold circulating water in the water cooling radiator 323 to the water tank 325. Specifically, by controlling the pumping efficiency of the water pump through the water cooling controller, the water cooling radiator 323 can achieve heat dissipation of different efficiencies according to actual use requirements.
[0040] like Figure 5 As shown, in this example, a heat insulation cotton 410 and a semiconductor refrigeration plate 420 are arranged between the heat dissipation mechanism 320 and the anode connection block 310; a third opening is arranged on the heat insulation cotton 410, and the semiconductor refrigeration plate 420 is embedded in the third opening; one side of the heat insulation cotton 410 is attached to the anode connection block 310, and the other side of the heat insulation cotton 410 is attached to the heat dissipation mechanism 320; one side of the semiconductor refrigeration plate 420 is attached to the anode connection block 310, and the other side of the semiconductor refrigeration plate 420 is attached to the heat dissipation mechanism 320. Specifically, the semiconductor refrigeration plate 420 is a device that uses the Peltier effect to achieve refrigeration. This effect causes the semiconductor chip on one side to absorb heat and the other side to release heat. Therefore, the heat dissipation efficiency of the bulb 200 can be improved by attaching the heat absorbing side of the semiconductor refrigeration plate 420 to the anode connection block 310 and the heat releasing side to the heat dissipation mechanism 320. The outer side of the semiconductor refrigeration plate 420 is provided with a heat insulation cotton 410 to prevent backflow during heat conduction.
[0041] like Figure 1 , Figure 4As shown, in this example, the power supply module includes a power supply and a transformer; the power supply is electrically connected to the transformer and the heat dissipation mechanism 320; the transformer is arranged inside the refrigeration box 100 and immersed in the coolant, and the transformer is electrically connected to the bulb 200. Specifically, the transformer includes a transformer 512 and a voltage doubler 511, both of which are used to increase the voltage provided by the power supply to the cathode end 210 of the bulb 200. Since the transformer 512 and the voltage doubler 511 also accumulate heat when working, they need to be immersed in the coolant when in use.
[0042] like Figure 1 , Figure 3 to Figure 6 As shown, in this example, the ray emitting device further includes a temperature sensor 600 and a control module; the temperature sensor 600 is electrically connected to the control module, the temperature sensor 600 is arranged on the anode connection block 310, and the temperature sensor 600 is used to obtain the temperature of the anode end 220 of the bulb 200; the control module is also electrically connected to the heat dissipation mechanism 320. Specifically, the temperature sensor 600 can detect the temperature of the anode connection block 310 and upload it to the control module, and the control module can be connected to the host computer or the display screen, so that the operator can feel the current heat of the bulb 200 more intuitively, and it is convenient for the operator to adjust the working power of the heat dissipation mechanism 320.
[0043] like Figure 1 , Figure 4 As shown, in this example, the ray emitting device further includes a tube fixing structure 700; the tube fixing structure 700 is disposed in the refrigerator 100 and fixed on the inner wall of the refrigerator 100; the tube 200 is disposed on the tube fixing structure 700. Specifically, the tube fixing structure 700 is used to fix the tube 200 in the refrigerator 100 so that the direction in which the tube 200 emits X-rays is directly opposite to the closed window 111 and is emitted from the closed window 111.
