[0056] Hereinafter, specific embodiments of the present application will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present application and do not limit the present application.

[0057] The present application provides a heat exchange housing for electrical equipment. The heat exchange housing is used to accommodate components of the electrical equipment. The heat exchange housing includes a shell, a partition and a pipeline. The shell is formed with a receiving space, and the partition is arranged in the shell and divides the receiving space into a plurality of receiving spaces. The plurality of receiving spaces include a first cavity and a second cavity, and the first cavity is a sealed cavity.

[0058] The pipeline is arranged in at least one of the shell and the partition, and the pipeline is distributed around the first cavity. The pipeline has an inlet and an outlet for the cooling medium to flow into and out of the pipeline, and the inlet and the outlet are respectively connected to the second cavity. The first cavity takes away the heat of the internal components through the shell, the partition and the pipeline, and the cooling medium does not enter the first cavity to contact the components in the first cavity. The second cavity is connected to the pipeline, and the components therein directly contact the cooling medium. The present application improves the space utilization of the accommodation space and the heat exchange efficiency of the heat exchange shell through the design of the heat exchange shell.

[0059] The present application also provides a specific electrical device, which is an X-ray generating device 100 having a heat exchange housing according to the first aspect of the present application. It can be understood that the X-ray generating device 100 of the present application is a device that can generate X-rays, which can be used in the medical field as a medical device for disease detection and treatment, and can also be used as an industrial non-destructive testing device and a security inspection detection device.

[0060] The X-ray generating device 100 includes a heat exchange housing 110 and a plurality of components housed in the heat exchange housing 110, wherein the plurality of components include 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 installed in the first cavity, and the transformer 154 is installed in the second cavity.

[0061] The following combination Figures 1 to 8 The illustrated embodiment illustrates the specific structure of the heat exchange housing 110 and the X-ray generating device 100 of the present application.

[0062] See also Figure 1 and Figure 2 In the illustrated embodiment, the heat exchange housing 110 is generally constructed in the shape of a rectangular parallelepiped, and the shape of the heat exchange housing 110 can be adjusted according to the actual installation space of the X-ray generating device 100. The housing 111 is formed with a receiving space 120, and the partition 112 is connected to the inner wall of the housing 111, thereby dividing the receiving space 120 into a plurality of small receiving spaces. The partition 112 can be integrally formed with the housing 111, or the partition 112 and the housing 111 can be produced separately and then connected into one by welding or the like.

[0063] In this embodiment, the shell 111 and the partition plate 112 are made of aluminum, which has good thermal conductivity and low cost. Of course, copper or other materials can also be selected.

[0064] The heat exchange housing 110 includes an outer shell 111 and a partition 112. The outer shell 111 is formed with a receiving space 120. The partition 112 is disposed in the outer shell 111 and divides the receiving space 120 into a plurality of receiving spaces, and the plurality of receiving spaces are used to receive a plurality of components of an electrical device (in this embodiment, an X-ray generating device 100).

[0065] 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 length direction D1 of the heat exchange housing 110. The transformer installation cavity 122 is located at the front end of the length direction D1.

[0066] The X-ray generating device 100 of the present application integrates the transformer installation cavity 122 and the oil tank cavity 121 in the shell 111 of the heat exchange housing 110, and separates the accommodating space 120 of the shell 111 by the partition 112, so that the integration is higher, and a separate transformer installation cavity 122 is provided to facilitate the inspection and maintenance of the transformer 154. The heat dissipation design can also be performed separately for the transformer 154, which is a component with a large heat generation.

[0067] 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 suitable for use in an environment with limited installation space.

[0068] 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, and 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 of 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.

[0069] The partition plate 112 is provided with a wire hole 113, and the control cavity 123, the wiring cavity 124 and the transformer installation cavity 122 are connected through the wire hole 113. In this embodiment, the control cavity 123 is also located at the bottom of the wiring cavity 124 and the transformer installation cavity 122.

[0070] 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 .

[0071] It is understandable that, because the control chamber 123 is separated from the transformer installation chamber 122 by the partition 112 and the wiring chamber 124, it is convenient for the components in the control chamber 123 to be connected to the components in the transformer installation 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 installation chamber 122 through the electrical adapter plate 114, the 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 chaotic entanglement of the wiring harness, and also facilitates the assembly and targeted maintenance of the X-ray generating device 100.

[0072] Of course, it is also possible to choose not to provide the additional wiring cavity 124 according to actual needs.

[0073] 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 4 The cavity door 160 is configured to be detachably connected to the housing 111 to open or close each receiving space. Figure 4 In the embodiment, the oil tank cavity 121, the transformer installation cavity 122 and the wiring cavity 124 are respectively provided with cavity doors 160. A sealing strip is provided at the cavity door 160 of the oil tank cavity 121. 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 respectively 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 (see Figure 2 ), used to open or close the control chamber 123.

[0074] 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.

[0075] The breathing valve 140 includes a valve body made of elastic material. When the breathing valve 140 is 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 the heat of internal components, the insulating oil will squeeze the valve body part to cause it to deform elastically, so that the part of the breathing valve 140 can absorb the expanded volume of the insulating oil after heating. When the temperature of the insulating oil drops, the volume decreases, and the valve body part of the breathing valve 140 will return to its initial state under the action of air pressure. In other words, the breathing valve 140 is actually a volume compensation device connected to the oil tank cavity 121.

[0076] Considering the heat dissipation of various components in the X-ray generating device 100, in this embodiment, the heat exchange housing 110 further includes a pipe 130 for heat dissipation. The pipe 130 can be arranged in at least one of the housing 111 and the partition 112, and the pipe 130 is hidden in the heat exchange housing 110, which will not affect the overall appearance of the X-ray generating device 100. By arranging the pipe 130 and the heat exchange housing 110 in an integrated manner, the cooling pipe 130 is prevented from occupying the accommodation space 120 of the heat exchange housing 110, thereby improving the space utilization rate of the heat exchange housing 110.

[0077] In this embodiment, the pipeline 130 is arranged in the housing 111. Preferably, the pipeline 130 is distributed around the oil tank cavity 121, and the pipeline 130 has an inlet 131 and an outlet 132 for the cooling medium to flow into and out of the pipeline 130. When the X-ray generating device 100 is working, the heat generated by the components in the oil tank cavity 121 can be transferred to the heat exchange housing 110 through the insulating oil, and the cooling medium flowing in the pipeline 130 can further take away the heat. Exemplarily, the cooling medium can be cooling gas. The inlet 131 and the outlet 132 can be connected to the cooling device respectively to achieve continuous heat exchange cooling of the heat exchange housing 110.

[0078] See also Figure 3 , the pipeline 130 is connected to the transformer installation cavity 122. That is, the inlet 131 and the outlet 132 are respectively connected to the transformer installation cavity 122. Thus, the cooling medium can flow in through the inlet 131, dissipate heat for the oil tank cavity 121, then flow into the transformer installation cavity 122, and then flow out through the outlet 132. Thus, the oil tank cavity 121 and the transformer installation cavity 122 can be cooled at the same time through the pipeline 130.

[0079] Specifically, the housing 111 includes a left side wall 115 and a right side wall 116 that are relatively distributed 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 .

[0080] See also Figures 6 to 8 The pipeline 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 confluence pipe 137. In this embodiment, the inlet side main pipe 133 is extended along the length direction D1 of the heat exchange shell 110 and is arranged in the left side wall 115. The outlet side main pipe 135 is extended along the length direction D1 and is arranged in the right side wall 116.

[0081] The inlet side main pipe 133 is connected to an inlet side branch pipe 134, and a plurality of inlet side branch pipes 134 are spaced and distributed on the left side wall 115. The outlet side main pipe 135 is connected to an outlet side branch pipe 136, and a plurality of outlet side branch pipes 136 are spaced and distributed on the right side wall 116.

[0082] 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 .

[0083] It can be understood that the pipe 130 in the heat exchange shell 110 specifically includes 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) to increase the distribution range of the pipe 130, thereby improving the heat dissipation efficiency of the shell. Preferably, the inlet side branch pipe 134 and the outlet side branch pipe 136 are both extended along the height direction D3.

[0084] The transformer installation cavity 122 is connected to the inlet 131 and the outlet 132 respectively. The transformer installation cavity 122 is arranged close to the right side wall 116, and 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 a portion of the pipeline 130 is shown, wherein the pipeline 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.

[0085] In this embodiment, the manifold 137 is U-shaped, including a pipe portion located in the rear end wall 117, and also including pipe portions located in the left side wall 115 and the right side wall 116. The manifold 137 is located below the inlet side main pipe 133 and the outlet side main pipe 135. Therefore, after the cooling air exchanges heat with the left side wall 115 through the inlet 131, the inlet side main pipe 133, and the inlet side branch pipe 134, it enters the right side wall 116 from the rear end wall 117 through the manifold 137, and then enters the transformer installation cavity 122 through the outlet side branch pipe 136 and the outlet side main pipe 135, and finally flows out from the outlet 132. Heat dissipation of the oil tank cavity 121 and the transformer installation cavity 122 is achieved.

[0086] Figure 3 and Figure 4 In the illustrated embodiment, 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 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 installation cavity 122, and the transformer 154 and the inductor 153 are fixed to the heat exchange housing 110 through fasteners.

[0087] See also Figure 3and 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 3 As 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.

[0088] The transformer 154 and the inductor 153 are spaced apart and distributed in the first direction D1 , and are spaced apart and distributed in the air-cooling flow direction, so that the heat can be better removed. A circuit board is arranged in the control cavity 123 .

[0089] 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, and ensure 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 155 for the connection terminal of the high-voltage circuit packaging module 152 to extend into, and a notch 155a is provided on one side of the insulating base 155 close to the high-voltage circuit packaging module 152 to facilitate the wiring of the connection terminal in the cavity to be electrically connected to the X-ray tube 151 above.

[0090] 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. Exemplarily, the elastic conductive member 158 is a spring (see Figure 5 ) or metal shrapnel.

[0091] The elastic conductive member 158 is installed in the oil tank cavity 121 through the metal seat 157. In this embodiment, the high-voltage circuit packaging module 152 is installed in the oil tank cavity 121 along the first direction D1 during assembly, and the cavity door 160 of the oil 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 (such as Figure 4 As shown in FIG. 1 , one end of the elastic conductive member 158 abuts against the bottom of the mounting hole 157a, and the other end extends out of the opening of the mounting hole 157a. By accommodating the elastic conductive member 158 in the mounting hole 157a, the elastic conductive member 158 provides elastic force to tightly mount the high-voltage circuit packaging module 152 in the oil tank cavity 121 while ensuring stability, and ensures reliable grounding of the high-voltage circuit packaging module 152 (grounding of the heat exchange housing 110).

[0092] In some embodiments, there are multiple elastic conductive members 158 and mounting holes 157a, and the multiple mounting holes 157a correspond to the multiple elastic conductive members 158. It can be 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.

[0093] It is understandable that by providing the metal seat 157, a plurality of elastic conductive members 158 can be conveniently arranged, and the metal seat 157 can be provided at any suitable position, as long as the elastic conductive members 158 provided thereon can be utilized to reliably and tightly install the high-voltage circuit packaging module 152 in the oil tank cavity 121. Thus, even when the X-ray generating device 100 is used in a mobile environment (for example, used on a mobile 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 against 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.

[0094] The circuit board is electrically connected to the high-voltage circuit packaging module 152 and the X-ray tube 151, and the circuit board is used to control the working process 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, and is used to provide power to the X-ray tube 151.

[0095] See also Figure 3Various 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 near the control chamber 123. Each interface 156 is electrically connected to the circuit board. Specifically, the interface 156 includes a power interface, a signal interface, a communication interface, and a housing grounding interface. The X-ray generating device 100 in this embodiment uses RS232 to communicate with the outside, and can also be adjusted according to actual needs, such as setting other types of communication interfaces. There can be two or more communication interfaces.
