[0053] Unless otherwise stated, numerical ranges herein include not only the entire range between its two endpoints but also the several sub-ranges contained therein.

[0054] Hereinafter, specific embodiments of the present application will be described in more detail with reference to the accompanying drawings. These drawings illustrate representative embodiments of the present application and do not limit the present application.

[0055] The present application provides a heat exchange housing for electrical equipment. The housing is used to house components of the electrical equipment. The housing includes an outer shell, a partition, and a pipe. The outer shell defines a storage space, and the partition is disposed within the outer shell to divide the storage space into multiple storage spaces. The multiple storage spaces include a first cavity and a second cavity, with the first cavity being a sealed cavity.

[0056] The pipes are disposed within at least one of the housing and the partition, and are distributed around the first cavity. The pipes have an inlet and an outlet for the cooling medium to flow into and out of the pipes, and the inlet and outlet are respectively connected to the second cavity. The first cavity removes heat from the internal components through the housing, the partition, and the pipes, and the cooling medium does not enter the first cavity and contact the components therein. The second cavity is in communication with the pipes, and the components therein directly contact the cooling medium. This application improves the space utilization of the housing and the heat exchange efficiency of the heat exchange housing through the design of the heat exchange housing.

[0057] This application also provides a specific electrical device, namely, an X-ray generating device 100 having a heat exchange housing according to the first aspect of this application. It will be understood that the X-ray generating device 100 of this application is a device capable of generating X-rays and can be used in the medical field as a medical device for disease detection and treatment, as an industrial nondestructive testing device, and as a security inspection device.

[0058] The X-ray generating device 100 includes a heat exchange housing 110 and multiple components housed therein, including an X-ray tube 151, a high-voltage circuit packaging module 152, and a transformer 154. The X-ray tube 151 and the high-voltage circuit packaging module 152 are mounted in a first cavity, and the transformer 154 is mounted in a second cavity.

[0059] The following combination Figures 1 to 8 The illustrated embodiment illustrates the specific structures of the heat exchange housing 110 and the X-ray generating device 100 of the present application.

[0060] See also Figure 1 and Figure 2 In the illustrated embodiment, the heat exchange housing 110 is generally constructed in a rectangular parallelepiped shape. The shape of the heat exchange housing 110 can be adjusted based on the actual installation space of the X-ray generator 100. The outer shell 111 defines a receiving space 120. Partitions 112 are connected to the inner wall of the outer shell 111, thereby dividing the receiving space 120 into multiple smaller receiving spaces. The partitions 112 can be integrally formed with the outer shell 111, or the partitions 112 and the outer shell 111 can be manufactured separately and then joined together by welding or other means.

[0061] In this embodiment, the 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.

[0062] The heat exchange housing 110 includes an outer shell 111 and a partition 112. The outer shell 111 defines a storage space 120. The partition 112 is disposed within the outer shell 111 and divides the storage space 120 into a plurality of storage spaces, each of which is used to house components of an electrical device (in this embodiment, the X-ray generator 100).

[0063] Specifically, the first cavity is the oil tank cavity 121, and the second cavity is the transformer installation cavity 122. The oil tank cavity 121 is a sealed cavity located at the rear end of the heat exchange housing 110 in the longitudinal direction D1. The transformer installation cavity 122 is located at the front end in the longitudinal direction D1.

[0064] The X-ray generator 100 of the present application integrates the transformer mounting cavity 122 and the oil tank cavity 121 within the outer shell 111 of the heat exchange housing 110. The housing 120 of the outer shell 111 is separated by a partition 112, resulting in a higher level of integration. Furthermore, the provision of a separate transformer mounting cavity 122 facilitates the inspection and maintenance of the transformer 154. This also allows for a separate heat dissipation design for the transformer 154, a component that generates relatively high heat.

[0065] The spatial layout of the X-ray generating device 100 and its heat exchange shell 110 of the present application is more reasonable, which can effectively improve the space utilization rate, thereby reducing the overall volume of the X-ray generating device 100, so that the X-ray generating device 100 can be used in an environment with limited installation space.

[0066] See also Figure 1 and Figure 2 The multiple receiving spaces include an oil tank cavity 121, a transformer installation cavity 122, a control cavity 123 and a wiring cavity 124. Figure 1 The oil tank cavity 121 and the transformer installation cavity 122 are arranged side by side along the length direction D1 of the heat exchange housing 110. The end where the oil tank cavity 121 is located is set as the rear end, and the transformer installation cavity 122 is located at the front end of the heat exchange housing 110. The wiring cavity 124 is also located at the front end in the length direction D1. Figure 1 and Figure 2 In this embodiment, the wiring cavity 124 and the transformer installation cavity 122 are arranged side by side along the width direction D2 or the height direction D3 of the heat exchange housing 110. The wiring cavity 124 and the transformer installation cavity 122 can also be arranged side by side along the height direction D3 of the heat exchange housing 110. Figure 2 The oil tank chamber 121 and the control chamber 123 are arranged side by side along the height direction D3 of the heat exchange housing 110, and the control chamber 123 is located at the bottom of the heat exchange housing 110. The control chamber 123 can also be arranged on the side of the oil tank chamber 121.

[0067] The partition 112 is provided with a wire hole 113, which connects the control cavity 123, the wiring cavity 124 and the transformer installation cavity 122. In this embodiment, the control cavity 123 is also located at the bottom of the wiring cavity 124 and the transformer installation cavity 122.

[0068] Further, see Figures 1 to 4 An electrical adapter plate 114 is provided on the partition 112 between the oil tank cavity 121 and the wiring cavity 124 , and the electrical adapter plate 114 is sealed and mounted to the partition 112 .

[0069] It is understandable that because the control chamber 123 is separated from the transformer mounting chamber 122 by the partition 112 and the wiring chamber 124, respectively, it is convenient for the components in the control chamber 123 to be connected to the components in the transformer mounting chamber 122 through the cables and the wire holes 113. In addition, because the oil tank chamber 121 is a sealed chamber, the components in the oil tank chamber 121 can be electrically connected to the components in the control chamber 123 or the transformer mounting chamber 122 through the electrical adapter plate 114, cables, and the wire holes 113 through the wiring chamber 124. The provision of the wiring chamber 124 makes the wiring arrangement more neat and scientific, avoids the tangled wiring harness, and also facilitates the assembly and targeted maintenance of the X-ray generating device 100.

[0070] Of course, it is also possible to choose not to provide the additional wiring cavity 124 according to actual needs.

[0071] See also Figure 1 、 Figure 3 and Figure 4 In a specific embodiment of the present application, the heat exchange housing 110 further includes a cavity door 160 (see Figure 4The cavity door 160 is configured to be detachably connected to the housing 111 to open or close each receiving space. Figure 4 The oil tank cavity 121, the transformer installation cavity 122 and the wiring cavity 124 are respectively provided with cavity doors 160. Among them, the cavity door 160 of the oil tank cavity 121 is provided with a sealing strip. The cavity door 160 can be fixed to the housing 111 by threaded fasteners, for example. Figure 3 In the embodiment, holes for engaging with threaded fasteners are provided at the transformer installation cavity 122 and the wiring cavity 124. In this embodiment, a cavity door 160 is also provided at the bottom of the heat exchange housing 110 (refer to Figure 2 ), used to open or close the control chamber 123.

[0072] See also Figure 3 The heat exchange housing 110 is also sealed with a breathing valve 140. Specifically, the housing 111 is provided with a through hole communicating with the oil tank cavity 121, and the breathing valve 140 is sealed and installed at the through hole.

[0073] Breathing valve 140 includes a valve body made of elastic material. When installed, the valve body at least partially protrudes into the oil tank cavity 121. When the insulating oil in the oil tank cavity 121 increases in volume due to absorbing heat from internal components, the insulating oil squeezes the valve body, causing it to elastically deform. This portion of the breathing valve 140 can absorb the heated expansion of the insulating oil. When the temperature of the insulating oil drops, its volume decreases, and the valve body of the breathing valve 140 returns to its original state under the influence of air pressure. In other words, the breathing valve 140 effectively acts as a volume compensation device connected to the oil tank cavity 121.

[0074] To dissipate heat from the various components within the X-ray generator 100, in this embodiment, the heat exchange housing 110 further includes a pipe 130 for dissipating heat. The pipe 130 can be disposed within at least one of the outer shell 111 and the partition 112. Concealed within the heat exchange housing 110, the pipe 130 does not affect the overall appearance of the X-ray generator 100. By integrating the pipe 130 with the heat exchange housing 110, the cooling pipe 130 does not occupy the accommodation space 120 of the heat exchange housing 110, thereby improving the space utilization of the heat exchange housing 110.

[0075] In this embodiment, the pipe 130 is disposed within the housing 111. 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 generating device 100 is in operation, the heat generated by the components within the oil tank cavity 121 can be transferred to the heat exchange housing 110 via the insulating oil, and the cooling medium flowing in the pipe 130 can further remove the heat. For example, the cooling medium can be cooling air. The inlet 131 and the outlet 132 can be connected to a cooling device respectively to achieve continuous heat exchange cooling of the heat exchange housing 110.

[0076] See also Figure 3 The pipe 130 is connected to the transformer installation cavity 122. Specifically, the inlet 131 and outlet 132 are connected to the transformer installation cavity 122. As a result, the cooling medium can flow in through the inlet 131, dissipate heat in the oil tank cavity 121, then flow into the transformer installation cavity 122 and out through the outlet 132. Thus, the pipe 130 can dissipate heat in both the oil tank cavity 121 and the transformer installation cavity 122 simultaneously.

[0077] Specifically, the outer shell 111 includes a left side wall 115 and a right side wall 116 that are opposite to each other in the width direction D2 of the heat exchange housing 110 , and a rear end wall 117 connected between the left side wall 115 and the right side wall 116 . Figure 4 In the embodiment, the inlet 131 and the outlet 132 are both arranged at the front end (at the front end wall) of the heat exchange shell 110 .

[0078] See also Figures 6 to 8 The pipe 130 includes an inlet-side main pipe 133, an inlet-side branch pipe 134, an outlet-side main pipe 135, an outlet-side branch pipe 136, and a conduit 137. In this embodiment, the inlet-side main pipe 133 extends along the longitudinal direction D1 of the heat exchange shell 110 and is disposed in the left side wall 115. The outlet-side main pipe 135 extends along the longitudinal direction D1 and is disposed in the right side wall 116.

[0079] The inlet main pipe 133 is connected to an inlet branch pipe 134 , which is spaced apart and distributed on the left side wall 115 . The outlet main pipe 135 is connected to an outlet branch pipe 136 , which is spaced apart and distributed on the right side wall 116 .

[0080] The conduit 137 is at least partially disposed in the rear end wall 117 and connects the inlet-side branch pipe 134 and the outlet-side branch pipe 136 .

[0081] It will be appreciated that the pipes 130 within the heat exchange housing 110 specifically include staggered main pipes (inlet-side main pipe 133 and outlet-side main pipe 135) and branch pipes (inlet-side branch pipe 134 and outlet-side branch pipe 136). This increases the distribution range of the pipes 130 and thereby improves the heat dissipation efficiency of the housing. Preferably, both the inlet-side branch pipe 134 and the outlet-side branch pipe 136 extend along the height direction D3.

[0082] The transformer installation cavity 122 is connected to the inlet 131 and the outlet 132. The transformer installation cavity 122 is arranged close to the right side wall 116. The outlet side main pipe 135 and at least one outlet side branch pipe 136 are both connected to the transformer installation cavity 122. Figure 4 , only part of the pipe 130 is shown, wherein the pipe 130 in the right side wall 116 includes a plurality of outlet side branches 136 extending along the height direction D3, and the outlet side branches 136 are connected to the outlet side main pipe 135 extending along the length direction D1.

[0083] In this embodiment, the manifold 137 is U-shaped and includes a duct portion located within the rear end wall 117, as well as duct portions located within the left and right side walls 115 and 116. Manifold 137 is located below the inlet-side main pipe 133 and the outlet-side main pipe 135. Thus, cooling air passes through the inlet 131, the inlet-side main pipe 133, and the inlet-side branch pipe 134, exchanges heat with the left side wall 115, then flows through manifold 137 from the rear end wall 117 to the right side wall 116. It then flows through the outlet-side branch pipe 136 and the outlet-side main pipe 135 into the transformer mounting cavity 122, ultimately exiting through outlet 132. This effectively dissipates heat from the oil tank cavity 121 and the transformer mounting cavity 122.

[0084] Figure 3 and Figure 4 In the embodiment shown, the X-ray tube 151 is disposed in the oil tank cavity 121 and is sealed and mounted on the top of the heat exchange housing 110 (see FIG. Figure 3 The high-voltage circuit packaging module 152 is disposed in the oil tank cavity 121. A transformer 154 and an inductor 153 are disposed in the transformer mounting cavity 122. The transformer 154 and the inductor 153 are fixed to the heat exchange housing 110 via fasteners.

[0085] See also Figure 3 and Figure 4 The transformer 154 and the inductor 153 are fixed to the upper wall of the transformer installation cavity 122, and the wind blown out from the outlet side branch pipe 136 below can directly blow to the transformer 154 and the inductor 153 suspended above the air outlet. Figure 3As shown, in the transformer installation cavity 122, there are air outlets extending along the first direction D1 (the air outlet of the outlet-side main pipe 135) and air outlets extending along the third direction D3 (the air outlet of the outlet-side branch pipe 136). The air outlet directions of the two air outlets intersect, which can greatly improve the heat dissipation effect of the transformer 154 and the inductor 153, and the heat dissipation is more uniform and the heat dissipation efficiency is higher.

[0086] The transformer 154 and the inductor 153 are spaced apart and distributed in the first direction D1 , so that their heat can be better removed by being spaced apart and distributed in the air-cooling overcurrent direction.

[0087] The oil tank cavity 121 is filled with insulating oil, which plays the role of insulation and heat dissipation. The high-voltage circuit packaging module 152 is installed in the oil tank cavity 121 through the mounting base 155. The input end of the high-voltage circuit packaging module 152 is electrically connected to the electrical adapter board 114. After the cavity door 160 of the oil tank cavity 121 is installed, the mounting base 155 can press the high-voltage circuit packaging module 152 tightly to prevent the high-voltage circuit packaging module 152 from loosening, ensuring that the high-voltage circuit packaging module 152 and the electrical adapter board 114 are tightly connected. The mounting base 155 is an insulating base, and a cavity is provided in the insulating base for the output terminal of the high-voltage circuit packaging module 152 to extend into, and a notch portion 155a is provided on the side of the insulating base close to the high-voltage circuit packaging module 152 to facilitate the wiring of the output terminal in the cavity to be electrically connected to the X-ray tube 151 above.

[0088] Further, see Figure 4 and Figure 5 In order to improve the safety of the X-ray generating device 100, an elastic conductive member 158 is further provided in the oil tank cavity 121. One end of the elastic conductive member 158 abuts against the high-voltage circuit packaging module 152, and the other end abuts against the cavity door 160 of the oil tank cavity 121. When the high-voltage circuit packaging module 152 is installed in the oil tank cavity 121, the elastic conductive member 158 is always in a compressed and deformed state, thereby ensuring reliable grounding of the high-voltage circuit packaging module 152. For example, the elastic conductive member 158 is a spring (see Figure 5 ) or metal shrapnel.

[0089] The elastic conductive member 158 is mounted in the fuel tank cavity 121 via the metal seat 157. In this embodiment, the high-voltage circuit packaging module 152 is installed in the fuel tank cavity 121 along the first direction D1 during assembly. The cavity door 160 of the fuel tank cavity 121 is located on the side of the rear end wall 117. The elastic conductive member 158 can be extended and retracted along the first direction D1. The metal seat 157 is provided with a mounting hole 157a extending along the first direction D1. The mounting hole 157a can be configured as a blind hole (e.g., Figure 4As shown in FIG, one end of elastic conductive member 158 abuts the bottom of mounting hole 157a, while the other end extends out of the opening of mounting hole 157a. By accommodating elastic conductive member 158 in mounting hole 157a, the elastic force provided by elastic conductive member 158 secures high-voltage circuit packaging module 152 within oil tank cavity 121 while ensuring stability. This also ensures reliable grounding of high-voltage circuit packaging module 152 (and therefore grounding of heat exchange housing 110).

[0090] In some embodiments, multiple elastic conductive members 158 and mounting holes 157a are provided, and the multiple mounting holes 157a correspond one to one with the multiple elastic conductive members 158. It is understood that by providing multiple elastic conductive members 158, reliable installation and effective grounding of the high-voltage circuit packaging module 152 can be ensured.

[0091] It is understood that the metal base 157 facilitates the arrangement of multiple elastic conductive members 158. The metal base 157 can be positioned at any suitable location, as long as the elastic conductive members 158 disposed thereon can be utilized to securely and tightly securely mount the high-voltage circuit packaging module 152 within the fuel tank cavity 121. Thus, even when the X-ray generating device 100 is used in a mobile environment (e.g., on a moving vehicle), reliable grounding can still be ensured, thereby improving safety. Figure 5 In the figure, the elastic conductive member 158 is a spring, and the metal seat 157 abuts the high-voltage circuit packaging module 152. When the high-voltage circuit packaging module 152 is installed in the oil tank cavity 121, the elastic conductive member 158 is located between the cavity door 160 of the oil tank cavity 121 and the metal seat 157, and is in a compressed and deformed state.

[0092] The circuit board is electrically connected to the high-voltage circuit packaging module 152 and the X-ray tube 151. It controls the operation of the high-voltage circuit packaging module 152 and the X-ray source. The high-voltage circuit packaging module 152 is electrically connected to the X-ray tube 151 and the transformer 154. The high-voltage circuit packaging module 152 is electrically connected to the secondary side of the transformer 154 to provide power to the X-ray tube 151.

[0093] See also Figure 3 Various interfaces 156 are also provided on the housing 111. The interfaces 156 are provided at the front end of the heat exchange housing 110 and are located near the control chamber 123. Each interface 156 is electrically connected to the circuit board. Specifically, the interfaces 156 include a power interface, a signal interface, a communication interface, and a chassis grounding interface. The X-ray generating device 100 in this embodiment uses RS232 to communicate with the outside world, and can also be adjusted according to actual needs, such as providing other types of communication interfaces. There can be two or more communication interfaces.
