Abstract
Description
Technical Field
[0001] This utility model relates to the field of X-ray tube technology, and in particular to an X-ray tube with a single-ended anode grounded. Background Technology
[0002] Traditionally, X-ray tubes have been used in a double-ended configuration (positive high voltage at the anode, negative high voltage at the cathode). During operation, the heat generated at the anode target surface is conducted away through thermal convection via insulating oil. Insulating oil has excellent insulation properties, but it has a low specific heat capacity, small heat capacity, and slow thermal conductivity. Therefore, the double-ended configuration of the X-ray tube limits its operation to either high-power intermittent operation or low-power long-term operation, restricting its high-power, long-duration application. Utility Model Content
[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an X-ray tube with a single-ended anode grounded end, which can significantly reduce anode heat and improve the performance of the X-ray tube for high-power long-term use.

[0023] Reference Figures 1 to 3 A single-ended, anode-grounded X-ray tube includes a tube 10, a connector 20, and a heat dissipation assembly 30. The tube 10 includes an anode 11 and a cathode 12. The connector 20 is disposed at one end of the tube 10 and is connected to the anode 11. The heat dissipation assembly 30 is disposed at one end of the connector 20 and is opposite to the tube 10. The heat dissipation assembly 30 dissipates heat from the connector 20.
[0024] It is understandable that connector 20 transfers the heat generated by anode 11 to heat dissipation component 30, which dissipates the heat, reduces the temperature of anode 11, and extends the working time of the X-ray tube under high power conditions.
[0025] It is worth noting that the double-ended application of X-ray tubes has low heat conduction efficiency and heat accumulation, making it difficult to meet the requirements of high power and long-term continuous operation. It can only be used for limited output power or intermittent application.
[0026] In the single-end anode grounding application, the potential of anode 11 is zero. This allows for the addition of a semiconductor cooling device, increasing the temperature difference between the target surface of the anode 11 and the heat dissipation device, thereby improving heat conduction efficiency.
[0027] With single-ended anode grounding, compared to double-ended grounding, the anode end has no high potential, making the X-ray tube assembly simpler and easier for mass production.
[0028] Reference Figure 1 The connector 20 includes a first clamp 21, a second clamp 22, and a locking screw 23. The first clamp 21 and the second clamp 22 are sleeved on the anode 11. The locking screw 23 connects the first clamp 21 and the second clamp 22.
[0029] It is worth noting that both the first clamp 21 and the second clamp 22 are provided with semi-cylindrical grooves. The first clamp 21 and the second clamp 22 can be tightened by locking screws, so that the first clamp 21 and the second clamp 22 are tightly attached to the anode 11.
[0030] Reference Figures 1 to 3 The heat dissipation assembly 30 includes a heat sink 31 and a cooling fan 32. The heat sink 31 is connected to the connector 20. The cooling fan 32 is mounted on the heat sink 31.
[0031] Understandably, heat sink 31 can significantly increase the heat dissipation area and improve the cooling effect of cooling fan 32.
[0032] Reference Figures 1 to 3 The heat dissipation assembly 30 also includes a thermoelectric cooler 33. The thermoelectric cooler 33 is disposed between the connector 20 and the heat sink 31.
[0033] It should be noted that the anode 11 generates heat during operation, which is transferred to the cold end of the thermoelectric cooler 33. The thermoelectric cooler 33 absorbs the heat to the hot end and then dissipates it through the heat sink 31.
[0034] Reference Figures 1 to 3 The thermoelectric cooler 33 is bonded to the connector 20. The connector 20 is bonded to the anode 11. The thermoelectric cooler 33 can transfer some of the heat from the anode 11.
[0035] Reference Figure 3 The first clamp 21 has a half-frame. The second clamp 22 has a half-frame. The half-frames on the first clamp 21 and the second clamp 22 combine to form the mounting frame 34. The semiconductor cooling chip 33 is housed in the mounting frame 34.
[0036] Reference Figure 3The heat sink 31 includes a base 311 and several fins 312. The base 311 is connected to the connector 20. The base 311 is attached to the thermoelectric cooler 33. Several fins 312 are disposed on the base 311. The cooling fan 32 is connected to the base 311 and is located on one side of the several fins 312.
[0037] It is worth noting that, in this embodiment of the invention, thermally conductive silicone grease is applied between the connector 20 and the anode 11. Thermally conductive silicone grease is also applied between the thermoelectric cooler 33 and the connector 20, and between the thermoelectric cooler 33 and the heat sink 31. The silicone grease increases thermal conductivity, further improving the heat dissipation effect of the heat sink assembly 30.
[0038] Since the connections between the anode 11, the thermoelectric cooler 33, the connector 20, and the heat sink 31 are all contact connections, the heat conduction efficiency is greatly improved. The thermoelectric cooler 33 can reduce the temperature of the anode 11 to below the ambient temperature, increasing the temperature difference between the anode 11 and the cold end of the thermoelectric cooler 33, which is more conducive to heat transfer. The above two points ensure that the X-ray tube is no longer limited by the heat accumulation of the anode 11, providing good conditions for the X-ray tube to perform at its maximum level.
[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
