[0054] In the following, the specific embodiments of the present utility model will be described in more detail with reference to the accompanying drawings, which show representative embodiments of the present utility model and are not intended to limit the present utility model.

[0055] The utility model provides a kind of X-ray source device 100, X-ray source device 100 includes shell 110 and the multiple components housed in shell 110, multiple components include X-ray tube 151, high voltage circuit package module 152 and transformer 154.

[0056] The shell 110 of the X-ray source device 100 according to the utility model includes an outer shell 111 and a partition 112. The outer shell 111 forms an accommodation space 120. The partition 112 is arranged in the outer shell 111 and divides the accommodation space 120 into multiple accommodation spaces for accommodating the multiple components of the X-ray source device 100.

[0057] Specifically, the multiple accommodation spaces include an oil tank cavity 121 and a transformer mounting cavity 122. The oil tank cavity 121 is a sealed cavity located at the rear end of the length direction D1 of the shell 110. The transformer mounting cavity 122 is located at the front end of the length direction D1.

[0058] The X-ray source device 100 of the utility model integrates the transformer mounting cavity 122 and the oil tank cavity 121 in the outer shell 111 of the shell 110, and further separates the accommodation space 120 of the outer shell 111 by the partition 112, which has a higher integration degree. In addition, a separate transformer mounting cavity 122 is provided to facilitate the maintenance and repair of the transformer 154. Furthermore, as described later, the transformer 154, which has a relatively large amount of heat, can be separately designed for heat dissipation.

[0059] The spatial layout of the X-ray source device 100 and its housing 110 of this utility model is more reasonable, which can effectively improve the space utilization rate, thereby reducing the overall volume of the X-ray source device 100 and making the X-ray source device 100 suitable for use environments with limited installation space.

[0060] First, combine Figures 1 to 4 The embodiment shown describes the specific structure of the housing 110 of an X-ray source device 100 according to the present invention.

[0061] See Figure 1 and Figure 2 In the illustrated embodiment, the housing 110 is generally constructed in a cuboid shape, and the shape of the housing 110 can be adjusted according to the installation space of the actual X-ray source device 100. The outer shell 111 forms an accommodating space 120, and a partition 112 is connected to the inner wall of the outer shell 111, thereby dividing the accommodating space 120 into multiple small receiving spaces. The partition 112 can be integrally formed with the outer shell 111, or the partition 112 and the outer shell 111 can be manufactured separately and then connected together by welding or other methods.

[0062] In this embodiment, the outer shell 111 and the partition 112 are made of aluminum, which has good thermal conductivity and low cost. Of course, copper or other materials can also be selected.

[0063] See Figure 1 and Figure 2 The multiple containment spaces include an oil tank cavity 121, a transformer mounting cavity 122, a control cavity 123, and a wiring cavity 124. See also... Figure 1 The oil tank cavity 121 and the transformer mounting cavity 122 are arranged side-by-side along the length D1 of the housing 110, with the end containing the oil tank cavity 121 designated as the rear end and the transformer mounting cavity 122 located at the front end of the housing 110. The wiring cavity 124 is also located at the front end along the length D1. See also... Figure 1 and Figure 2 In this embodiment, the wiring cavity 124 and the transformer mounting cavity 122 are arranged side-by-side along the width direction D2 or the height direction D3 of the housing 110. The wiring cavity 124 and the transformer mounting cavity 122 may also be arranged side-by-side along the height direction D3 of the housing 110. See also... Figure 2 The fuel tank cavity 121 and the control cavity 123 are arranged side by side along the height direction D3 of the housing 110, with the control cavity 123 located at the bottom of the housing 110. The control cavity 123 may also be located on the side of the fuel tank cavity 121.

[0064] The partition plate 112 is provided with a wire hole 113, and the control cavity 123, the wire routing cavity 124 and the transformer mounting cavity 122 are communicated through the wire hole 113. In the embodiment, the control cavity 123 is also located at the bottom of the wire routing cavity 124 and the transformer mounting cavity 122.

[0065] Further, referring to Figures 1 to 4 , the partition plate 112 between the oil tank cavity 121 and the wire routing cavity 124 is provided with an electric adapter plate 114, and the electric adapter plate 114 is sealingly mounted to the partition plate 112.

[0066] It can be understood that, because the control cavity 123 is separated from the wire routing cavity 124 and the transformer mounting cavity 122 by the partition plate 112, the components in the control cavity 123 can be connected to the components in the transformer mounting cavity 122 through cables and the wire hole 113. Moreover, because the oil tank cavity 121 is a sealed cavity, the components in the oil tank cavity 121 can be electrically connected to the components in the control cavity 123 or the transformer mounting cavity 122 through the electric adapter plate 114, cables and the wire hole 113 via the wire routing cavity 124. The provision of the wire routing cavity 124 makes the wire arrangement more orderly and scientific, avoids the mess of the wire harness, and facilitates the assembly and targeted maintenance of the X-ray source device 100.

[0067] Of course, the wire routing cavity 124 can also be omitted according to actual needs.

[0068] Referring to Figure 1 , Figure 3 and Figure 4 , in one specific embodiment of the present application, the shell 110 further comprises a cavity door 160 (see Figure 4 ). The cavity door 160 is configured to be detachably connected to the outer shell 111 to open or close each accommodation space. Figure 4 In the embodiment, the oil tank cavity 121, the transformer mounting cavity 122 and the wire routing cavity 124 are respectively provided with a cavity door 160. Among them, the cavity door 160 at the oil tank cavity 121 is provided with a sealing strip. The cavity door 160 can be fixed to the outer shell 111, for example, by a threaded fastener, Figure 3 In the embodiment, holes for cooperating with threaded fasteners are respectively provided at the transformer mounting cavity 122 and the wire routing cavity 124. In the embodiment, the bottom of the shell 110 is also provided with a cavity door 160 (see Figure 2 ) for opening or closing the control cavity 123.

[0069] Referring to Figure 3 , the shell 110 is also sealingly mounted with a breather valve 140. Specifically, the outer shell 111 is provided with a through hole in communication with the oil tank cavity 121, and the breather valve 140 is sealingly mounted to the through hole.

[0070] The breathing valve 140 comprises a valve body made of elastic material, which at least partially protrudes into the oil tank cavity 121 when the breathing valve 140 is installed. When the insulating oil in the oil tank cavity 121 increases in volume due to absorbing heat from the internal components, the insulating oil will press the valve body part to elastically deform, so that part of the breathing valve 140 can absorb the expansion volume of the insulating oil after being heated. When the temperature of the insulating oil decreases, the volume decreases, and the valve body part of the breathing valve 140 will return to the initial state under the action of air pressure. In other words, the breathing valve 140 is actually a volume compensation device in communication with the oil tank cavity 121.

[0071] In view of heat dissipation of the various components in the X-ray source device 100, in the embodiment, the shell 110 further comprises a pipe 130 for heat dissipation. The pipe 130 can be arranged in at least one of the outer shell 111 and the partition 112, and the pipe 130 is hidden in the shell 110 and does not affect the overall appearance of the X-ray source device 100. By integrating the pipe 130 and the shell 110, the cooling pipe 130 occupies the accommodation space 120 of the shell 110, and the space utilization of the shell 110 is improved.

[0072] Preferably, the pipe 130 is distributed around the oil tank cavity 121, and the pipe 130 has an inlet 131 and an outlet 132 for the cooling medium to flow into and out of the pipe 130. When the X-ray source device 100 is working, the heat generated by the components in the oil tank cavity 121 can be transmitted to the shell 110 through the insulating oil, and the cooling medium flowing in the pipe 130 can further take away the heat.

[0073] Referring to Figure 3 , the pipe 130 is in communication with the transformer mounting cavity 122. That is, the inlet 131 and the outlet 132 are respectively in communication with the transformer mounting cavity 122. In this way, the cooling medium can flow into the oil tank cavity 121 via the inlet 131, and then flow into the transformer mounting cavity 122 after dissipating heat to the oil tank cavity 121, and then flow out via the outlet 132, so that the oil tank cavity 121 and the transformer mounting cavity 122 can be cooled simultaneously by the pipe 130.

[0074] Figure 4 In the embodiment, the inlet 131 and the outlet 132 are both arranged at the front end of the shell 110. Preferably, the pipe 130 in the shell 110 specifically comprises a plurality of main pipes and branch pipes staggered distributed, so as to increase the distribution range of the pipe 130, thereby improving the heat dissipation efficiency of the shell. Figure 4 In the embodiment, only part of the pipe 130 is shown, and the pipe 130 in the outer shell 111 comprises a plurality of branch pipes extending along the height direction D3, the branch pipes can be communicated by a main pipe extending along the length direction D1, and the inlet 131 and the outlet 132 are communicated.

[0075] Figure 3 and Figure 4In the shown embodiment, the X-ray source device 100 comprises a housing 110, an X-ray tube 151, a high voltage circuit package module 152 and a transformer 154. The X-ray tube 151 is arranged in the oil tank cavity 121 and is sealingly mounted on the top of the housing 110 (see Figure 3 ). The high voltage circuit package module 152 is arranged in the oil tank cavity 121. The transformer 154 and the inductor 153 are arranged in the transformer mounting cavity 122 and are fixed to the housing 110 by fasteners. The circuit board is arranged in the control cavity 123.

[0076] The oil tank cavity 121 is filled with insulating oil which serves as insulation and heat dissipation. The high voltage circuit package module 152 is mounted in the oil tank cavity 121 by a mounting base 155. The input of the high voltage circuit package module 152 is electrically connected to the electric adapter plate 114. When the door 160 of the oil tank cavity 121 is mounted, the mounting base 155 can press the high voltage circuit package module 152 tightly to prevent the high voltage circuit package module 152 from loosening and ensure that the high voltage circuit package module 152 is tightly connected to the electric adapter plate 114.

[0077] The circuit board is electrically connected to the high voltage circuit package module 152 and the X-ray tube 151 and is used to control the working process of the high voltage circuit package module 152 and the X-ray source. The high voltage circuit package module 152 is electrically connected to the X-ray tube 151 and the transformer 154. The high voltage circuit package module 152 is electrically connected to the secondary side of the transformer 154 and is used to provide power supply for the X-ray tube 151.

[0078] Referring to Figure 3 The housing 111 is also provided with various interfaces 156 which are arranged at the front end of the housing 110 and are close to the control cavity 123. The interfaces 156 are electrically connected to the circuit board.

The X-ray source device 100 in the embodiment adopts RS232 to communicate with the outside and other types of communication interfaces can also be arranged according to actual needs. The communication interface can be two or more.
