[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] The technical solutions disclosed in the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0018] Please refer to Figures 1 to 5 This utility model discloses a radiation generating device. The disclosed radiation generating device can be an X-ray generating device. Of course, the disclosed radiation generating device can also be other types of radiation generating devices. This application does not specifically limit the type of radiation generating device.

[0019] The disclosed ray generating device comprises a ray tube assembly 100, a high-voltage power supply 200, a flange 300, a first shell 400, and a fan 600. The ray tube assembly 100, the high-voltage power supply 200, the flange 300, the first shell 400, and the fan 600 of the ray generating device in the present application are integrated together as an integrated structure.

[0020] The high-voltage power supply 200 and the ray tube assembly 100 are respectively arranged on opposite sides of the flange 300. The ray tube assembly 100 is a ray output source. The ray tube assembly 100 generates electrons through a cathode. The electrons are accelerated to high speed through a high-voltage electric field between the cathode and an anode, and then hit an anode target surface, thereby generating rays. The high-voltage power supply 200 is used to output a stable high-voltage electric field between the cathode and the anode.

[0021] The first shell 400 covers the high-voltage power supply 200, and an opening of the first shell 400 is connected with the flange 300. There is a gap between an inner wall of the first shell 400 and an outer wall of the high-voltage power supply 200.

[0022] A side wall of the first shell 400 is provided with an air inlet, and the fan 600 is arranged at the air inlet. The flange 300 is provided with a ventilation opening 310, and the ventilation opening 310 is in communication with a first space surrounded by the inner wall of the first shell 400 and the outer wall of the high-voltage power supply 200.

[0023] When the fan 600 rotates, the fan 600 can blow gas to the first space surrounded by the inner wall of the first shell 400 and the outer wall of the high-voltage power supply 200 through the air inlet, so as to cool the high-voltage power supply 200. The gas entering the first space surrounded by the inner wall of the first shell 400 and the outer wall of the high-voltage power supply 200 can be discharged through the ventilation opening 310, and the gas discharged from the ventilation opening 310 can cool the ray tube assembly 100.

[0024] The ray generating device disclosed by the embodiment of the present application can protect the high-voltage power supply 200 by covering the high-voltage power supply 200 with the first shell 400 and connecting the opening of the first shell 400 with the flange 300. The fan 600 is arranged at the air inlet, so that the fan 600 can blow gas to the first space surrounded by the inner wall of the first shell 400 and the outer wall of the high-voltage power supply 200 through the air inlet, so as to cool the high-voltage power supply 200. The gas in the first space surrounded by the inner wall of the first shell 400 and the outer wall of the high-voltage power supply 200 can be discharged through the ventilation port 310, and the gas discharged from the ventilation port 310 can cool the ray tube assembly 100. By cooling the high-voltage power supply 200 and the ray tube assembly 100, the problem that the temperature of the ray generating device is high during work and affects the performance can be alleviated.

[0025] To better cool the ray tube assembly 100, the ventilation port 310 can be optionally inclined to extend towards one side of the ray tube assembly 100, so that the gas flowing out of the ventilation port 310 can directly blow to the outer wall of the ray tube assembly 100, thereby increasing the speed of the airflow flowing through the surface of the ray tube assembly 100, and more gas can flow through the surface of the ray tube assembly 100, thereby better cooling the ray tube assembly 100.

[0026] Optionally, the ventilation port 310 can be multiple, and the multiple ventilation ports 310 can be uniformly distributed around the ray tube assembly 100.

[0027] The ray generating device disclosed by the embodiment of the present application can be uniformly distributed around the ray tube assembly 100 by arranging multiple ventilation ports 310, so that the gas flowing out of the multiple ventilation ports 310 can uniformly cool each part of the ray tube assembly 100.

[0028] To better cool the high-voltage power supply 200, the air inlet can be optionally located at the end of the first shell 400 away from the flange 300, so that the air entering the first shell 400 from the air inlet can flow through more area of the high-voltage power supply 200, thereby better cooling the high-voltage power supply 200.

[0029] Of course, the position of the air inlet can also be other positions, and the embodiment of the present application does not specifically limit the position of the air inlet.

[0030] Optionally, the first shell 400 and the flange 300 can be arranged in a stacking direction (i.e. the direction in which the first shell 400 and the flange 300 are arranged in a stack, such as the direction shown in FIG. 1). Figure 1The side wall of the first shell 400 can be provided with a plurality of air inlets in the direction around the stacking direction of the first shell 400 and the flange 300. The fan 600 can be provided in one-to-one correspondence with the plurality of air inlets. In the embodiment of the present application, the stacking direction of the first shell 400 and the flange 300 refers to the direction in which the first shell 400 and the flange 300 are arranged in an overlapping manner. For example Figure 1 The vertical direction in the upright posture of the X-ray generating device.

[0031] The X-ray generating device disclosed in the embodiment of the present application blows air into the first shell 400 in the direction around the stacking direction of the first shell 400 and the flange 300 by the plurality of fans 600, so that air can be blown at a plurality of positions in the circumferential direction around the high-voltage power supply 200, thereby making the cooling effect on each part of the high-voltage power supply 200 relatively uniform.

[0032] To prevent foreign matter or too much dust from entering the first shell 400, the X-ray generating device can optionally further include a first ventilation grille 700.

The second shell 500 can be provided with an air outlet, and the ventilation opening 310 can be in communication with a second space surrounded by the inner wall of the second shell 500 and the outer wall of the X-ray tube assembly 100. The gas discharged from the ventilation opening 310 can enter the second space surrounded by the inner wall of the second shell 500 and the outer wall of the X-ray tube assembly 100, so that the gas for cooling the X-ray tube assembly 100 can be gathered in the second space, thereby better cooling the X-ray tube assembly 100. The gas after cooling the X-ray tube assembly 100 can be discharged through the air outlet.

[0034] Optionally, the air outlet can be located at the top of the second shell 500, and the top of the second shell 500 is opposite to the flange 300. By arranging the air outlet at the top of the second shell 500, the area of the air flowing through the X-ray tube assembly 100 in the second shell 500 is relatively large, thereby improving the cooling capacity of the X-ray tube assembly 100.

[0035] To prevent foreign matter or too much dust from entering the second shell 500, the X-ray generating device can optionally further include a second ventilation grille 800. The air outlet can be provided with the second ventilation grille 800, so that foreign matter or too much dust can be prevented from entering the second shell 500.

[0036] Optionally, the ray generating device can further comprise a control module, the high-voltage power supply 200 can comprise a circuit body and a glue structure, the circuit body can be arranged inside the glue structure, and the control module can be arranged in a space formed by the inner wall of the first shell 400 and the outer wall of the glue structure. The control module can be electrically connected with the circuit body. The control module comprises components such as control circuit, which is used for controlling the on-off of the circuit in the ray generating device, and giving voltage and current values.

[0037] The control module is arranged in the space formed by the inner wall of the first shell 400 and the outer wall of the glue structure (or the outer wall of the high-voltage power supply 200), so that effective cooling of the control module can be realized.

[0038] Further optionally, in the stacking direction of the first shell 400 and the flange 300, the air inlet can be opposite to the control module.

[0039] The ray generating device disclosed in the embodiments of the present application sets the air inlet at a position opposite to the control module in the stacking direction of the first shell 400 and the flange 300, so that more gas entering from the air inlet flows through the control module, thereby better cooling the control module.

[0040] Optionally, the ray tube assembly 100 can comprise a cavity shell 120 and a ray tube 110, the cavity shell 120 can be sealingly connected with the flange 300, and the ray tube 110 can be arranged in the cavity shell 120 and partially located in the cavity shell 120. The cavity shell 120 can be filled with a gas insulation medium or a liquid insulation medium.

[0041] The ray generating device disclosed in the embodiments of the present application fills the cavity shell 120 with a gas insulation medium or a liquid insulation medium, so that the gas insulation medium or the liquid insulation medium can insulate and protect the ray tube 110.

[0042] In order to facilitate the operation personnel to carry or move the ray generating device, optionally, the bottom of the first shell 400 opposite to the flange 300 can be provided with an anti-falling groove 410, and the opening of the anti-falling groove 410 can be directed to the side away from the flange 300. When the operation personnel carries or moves the ray generating device, the operation personnel's hand can be buckled at the anti-falling groove 410, so as to prevent the operation personnel's hand from being separated.
