Description

Technical Field

[0001] This utility model belongs to the field of X-ray source technology, specifically relating to an X-ray source cooling device. Background Technology

[0002] When an X-ray source is working, 99% of its power is converted into heat energy, and only 1% of the energy is converted into effective radiation. Therefore, the heat dissipation effect of the X-ray source directly determines the detection performance of the equipment.

[0003] Existing X-ray inspection equipment only fills the housing where the X-ray emitter is installed with cooling oil. The heat from the X-ray emitter is dissipated into the cooling oil, resulting in a higher temperature of the cooling oil near the X-ray emitter and a lower temperature of the cooling oil farther away. This temperature imbalance of the cooling oil leads to low heat dissipation efficiency. Furthermore, changes in the temperature of the cooling oil also cause changes in the pressure inside the housing, thereby affecting the performance and stability of the inspection equipment. Utility Model Content

[0004] In view of this, in order to solve the problems mentioned in the background art, the purpose of this utility model is to provide an X-ray source cooling device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An external cooling box includes a hollow box body and sealing members connected to both ends of the hollow body. The hollow body is filled with an insulating refrigerant.

[0038] like Figures 1 to 8 As shown, the X-ray source cooling device proposed in this utility model includes an outer cooling box 1, an inner shielding barrel 2, and an X-ray tube 3. Specifically, the outer cooling box 1 is made of aluminum profile and carbon fiber plate. The aluminum profile effectively meets the heat dissipation requirements of the outer cooling box 1, while the carbon fiber plate reduces the overall weight of the device while meeting structural strength requirements. The outer cooling box 1 is filled with insulating refrigerant. The inner shielding barrel 2 is used to install the X-ray tube 3 and shield it from radiation. It also guides the insulating refrigerant to the vicinity of the X-ray tube 3 to achieve rapid heat dissipation and cooling of the X-ray tube 3, thereby ensuring the stable operation of the X-ray tube 3.

[0039] In one specific embodiment, the external cooling box 1 includes as follows: Figures 2-4The diagram shows a housing 11 with a hollow core 111. Specifically, the insulating refrigerant is filled inside the hollow core 111, and the housing 11 is made of aluminum profile material to achieve rapid heat dissipation of the insulating refrigerant.

[0040] In this embodiment, refer to Figure 7 As shown, the inner shielding barrel 2 is provided with an inner cavity 201 and an inlet channel 202 and an outlet channel 203 that guide the insulating refrigerant to flow through the inner cavity 201. The X-ray tube 3 is installed in the inner cavity 201 of the inner shielding barrel 2, and the radiant heat of the X-ray tube 3 is carried away by the insulating refrigerant flowing through the inner cavity 201.

[0041] It should be noted that the inner shielding barrel 2 includes a main body 21 and a first end cap 22 and a second end cap 23 fixed to both ends of the main body 21. When the inner shielding barrel 2 is installed horizontally, as... Figure 7 and Figure 8 As shown, a first through hole forming the inlet channel 202 is provided in the upper middle part of the first end cap 22, and second through holes forming the outlet channels 203 are symmetrically provided at the top and bottom of the second end cap 23. The central axes of the first and second through holes are inclined towards each other or in opposite directions relative to the central axis of the inner shielding barrel 2. Based on this structural design, on the one hand, it can ensure that the insulating refrigerant with a lower temperature enters the inner cavity 201 along the inlet channel 202, and the insulating refrigerant with a higher temperature flows out of the inner cavity 201 along the outlet channel 203, thereby realizing the circulation of the insulating refrigerant in the inner cavity 201 and improving the cooling effect of the X-ray tube 3; on the other hand, it prevents the X-rays emitted by the X-ray tube 3 from directly passing through the through holes, thereby effectively avoiding the leakage of side rays.

[0042] In one exemplary embodiment, the inner sides of the first end cap 22 and the second end cap 23 are provided with sealing fit structures corresponding to the shapes of the two ends of the main body 21. The X-ray tube 3 is fixedly installed in the inner cavity 201 of the inner shielding barrel 2 through the first end cap 22 and the second end cap 23, thereby facilitating the production and processing of the inner shielding barrel 2 and the assembly of the inner shielding barrel 2 and the X-ray tube 3. Specifically, the first end cap 22 and the second end cap 23 are made of lead oxide material, which can ensure the shielding performance and insulation performance of the inner shielding barrel 2.

[0043] In one specific embodiment, the external cooling box 1 further includes, for example, Figure 1 and Figure 3The sealing member 12 shown connects the two ends of the hollow 111. Specifically, the sealing member 12 includes a balancing chamber 121 and a spacer 122 that dynamically isolates the balancing chamber 121 from the hollow 111. The spacer 122 is at least partially configured as a deformable elastic partition structure to achieve dynamic balance between the oil pressure in the hollow 111 and the air pressure in the balancing chamber 121 when the temperature of the insulating refrigerant changes.

[0044] For example, the sealing member 12 includes, as shown in the example Figure 3 The side plate 123 fixed to the end of the housing 11 and the sealing gasket 124 sealingly abutting between the side plate 123 and the housing 11 are shown. Specifically, as Figure 6 The sealing gasket 124 shown is recessed into the hollow 111 to form the spacer 122, and a sealing ring 125 is formed around the spacer 122. Specifically, when installing the sealing member 12, an annular cavity 126 is formed between the side plate 123 and the housing 11. The sealing ring 125 is sealed and engaged within the annular cavity 126, thus sealing the balance chamber 121 between the sealing gasket 124 and the side plate 123 to prevent air leakage; and isolating external air from the cooling oil inside the hollow 111 to prevent oil leakage. It should be noted that the sealing gasket 124 is made of nitrile rubber, which has a high coefficient of expansion, enabling it to effectively adapt to temperature changes in the cooling oil while ensuring a seal, and effectively meeting the deformation requirements of the spacer 122 during pressure dynamic balancing.

[0045] To further improve the dynamic balance between oil pressure and air pressure, the balancing chamber 121 preferably includes the following components: Figure 3 The first cavity 1211 formed on the sealing gasket 124 and the second cavity 1212 formed on the side plate 123 are shown. The first cavity 1211 is recessed into the hollow 111, and the second cavity 1212 is recessed outward from the hollow 111. This provides a balance cavity 121 with a larger pressure regulation space while ensuring the structural strength of the sealing gasket 124 and the side plate 123.

[0046] In this embodiment, it should also be noted that the annular clamping cavity 126 specifically includes, as follows: Figure 5 The inner groove 1261 and the opening 1262 shown are configured such that the inner groove 1261 is partially open through the opening 1262. The sealing ring 125 includes a first ring portion 1251 and a second ring portion 1252 that respectively fit into the inner groove 1261 and the opening 1262, thereby further improving the sealing effect of the sealing gasket 124.

[0047] In addition, the sealing ring 125 also includes, for example Figure 6The third ring portion 1253 shown connects the second ring portion 1252 and the spacer 122, and the connection between the third ring portion 1253 and the second ring portion 1252 and the spacer 122 is rounded to facilitate the integral molding of the entire sealing gasket 124. In addition, the rounded structure can effectively enhance the structural strength without increasing the overall wall thickness of the sealing gasket 124, thereby extending the service life of the sealing gasket 124.

[0048] In summary, this utility model provides an X-ray source cooling device: through the inlet channel 202 and outlet channel 203 inclinedly arranged on the inner shielding barrel 2, on the one hand, the insulating refrigerant is circulated, thereby improving the heat dissipation and cooling effect of the X-ray tube 3; on the other hand, X-rays are prevented from directly passing through the channels, thereby effectively preventing side radiation leakage; by setting a sealing component 12 adapted to the circulating insulating refrigerant, the dynamic balance between the oil pressure in the hollow 111 and the air pressure in the balance chamber 121 is achieved, and the sealing component 12 specifically includes a spacer 122 and a sealing ring 125 that can be integrally formed, which has the advantages of simple structure, convenient processing and installation, low cost, and long service life.
