[0002] A CT device is a medical device that can be used to generate accurate body images to assist doctors in disease diagnosis and treatment. It uses X-ray and computer technologies to provide high-resolution cross-sectional images and has many important functions. The radiation source fuel tank is one of the devices in the high-voltage oil section of the accelerator for medical imaging of CT equipment. During the imaging process, it plays a role in compressing oil and gas to generate high voltage. Its principle is that through a discharge device, arc light is generated to change the liquid medium into gas, forming an ionized gas, so that electrons under the action of an electric field accelerate and collide to generate more ions, thus forming discharge and other phenomena.

[0003] However, traditional CT devices have the following disadvantages:

[0004] At present, some CT devices on the market do not have a heat dissipation device, which results in a long cooling time required after each shot, bringing a lot of inconvenience to customers. Some devices are equipped with a heat dissipation device, but the heat dissipation efficiency is very low, unable to achieve continuous shooting without limit, and the price is relatively high. Most of them are equipped with a temperature-collecting plate. Therefore, there is an urgent need for a heat dissipation device with low cost and high heat dissipation efficiency to dissipate heat from the product. Content of the Utility Model

Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] Please refer to Figures 1-5 , the present invention provides a heat dissipation device for a radiation source fuel tank of an X-ray imaging device, including a support base 1. A radiation source fuel tank 9 is fixedly installed at the top end of the support base 1. Glands 11 are fixedly installed on both sides of the radiation source fuel tank 9. A plurality of first heat sinks 4 are fixedly installed at both ends of the two glands 11 on the opposite sides. A plurality of second heat sinks 10 are fixedly installed in the middle of the two glands 11 on the opposite sides. Heat dissipation seats 13 are fixedly installed on both sides of the top end of the support base 1. First fans 3 are fixedly installed on the opposite sides of the two heat dissipation seats 13. A fan control board mounting plate 5 is fixedly installed at the top end of the radiation source fuel tank 9. A fan mounting plate 6 is fixedly installed at the top end of one side of the fan control board mounting plate 5. A plurality of second fans 12 are fixedly installed at the bottom end of the fan mounting plate 6. A fan control board 8 is fixedly installed on one side of the fan control board mounting plate 5.

[0024] Both of the two first blowers 3 and several second blowers 12 include a blower frame 301 and a second filter plate 304. On one side of the inner wall of the blower frame 301, a first filter plate 309 is slidably connected. At one end of both sides of the inner wall of the blower frame 301, movable grooves 302 are opened. Inside both of the two movable grooves 302, movable blocks 307 are slidably connected. The opposite ends of the two movable blocks 307 are respectively fixedly connected to both ends of the second filter plate 304. On one side of the second filter plate 304, a stepper motor 306 is fixedly installed. The output end of the stepper motor 306 is fixedly installed with a blade paddle 308. A plurality of air holes 305 are opened on the surface of the blower frame 301. On one side of both of the two movable blocks 307, connecting springs 303 are fixedly installed. One ends of the two connecting springs 303 are respectively fixedly connected to the opposite sides of the two movable grooves 302. At both ends of one side of the inner wall of the blower frame 301, fixed shells 310 are fixedly installed. Inside both of the two fixed shells 310, length rods 311 are slidably connected. The ends of the two length rods 311 far from the fixed shells 310 are fixedly connected to the opposite sides of the first filter plate 309. Between the two length rods 311 and the two fixed shells 310, support springs 312 are fixedly installed. After the stepper motor 306 is powered on and starts, the stepper motor 306 drives the blade paddle 308 to rotate. The gas first passes through the first filter plate 309 to intercept impurities and then is discharged from the blower frame 301 through the second filter plate 304. After the gas contacts the first filter plate 309, the length rod 311 slides along the fixed shell 310, and the length rod 311 pulls the support spring 312 from one side. The support spring 312 has elasticity, and the support spring 312 undergoes elastic deformation to buffer the pulling force. Also, the second filter plate 304 drives the movable block 307 to slide along the movable groove 302, and the movable block 307 squeezes the connecting spring 303 from one side. The connecting spring 303 has elasticity, and the connecting spring 303 undergoes elastic deformation to buffer the squeezing force. The first filter plate 309 and the second filter plate 304 slide back and forth, which is convenient for the filter plates to efficiently intercept impurities in the gas.

[0025] One side of the blower frame 301 of the first blower 3 is fixedly connected to the heat dissipation seat 13, and one side of the blower frame 301 of the second blower 12 is fixedly connected to the blower mounting plate 6. The blower frames 301 are respectively installed on the heat dissipation seat 13 and the blower mounting plate 6.

[0026] Both of the two first blowers 3 and several second blowers 12 are connected to the blower control board 8. The user controls the start and stop of the first blowers 3 and the second blowers 12 by operating the blower control board 8.

[0027] At the connection between the blower control board mounting plate 5 and the blower mounting plate 6, a rubber strip 7 is fixedly installed. The rubber strip 7 fills the gap between the blower control board mounting plate 5 and the blower mounting plate 6 to improve the connection stability between the two.

[0028] A plurality of air ducts 2 are provided on the surfaces of the two heat sinks 13, and the provision of the air ducts 2 facilitates the blowing of the gas blown out by the first blower 3 to the surface of the radiation source fuel tank 9.

[0029] A thermal grease film 14 is laid on the surface of the radiation source fuel tank 9, and the thermal grease film 14 directly conducts heat transfer and dissipates heat from the outside of the radiation source fuel tank 9.

[0030] In the use of the embodiment of the present application: A large amount of heat will be generated when the radiation source fuel tank 9 is working. If the heat cannot be dissipated well, it will affect the performance of the radiation source fuel tank, and in severe cases, the radiation source fuel tank 9 may be damaged. This device directly absorbs the heat generated when the radiation source fuel tank 9 is working through the first heat sink 4 and the second heat sink 10. When powered on, the first blower 3 and the second blower 12 will be controlled by the blower control board 8 to rotate the first blower 3 and the second blower 12; then the heat is taken away through the first blower 3 passing through the professional air duct 2. Among them, the two first blowers 3 below blow air upward, and several second blowers 12 above suck air; this makes the air pressure at the upper end small, and the hot air goes upward. Incidentally, the air with reduced temperature can also be inhaled through the second blower 12 to form a cycle of hot and cold air, ensuring that the radiation source fuel tank 9 can work normally.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
