This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0032] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0033] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0034] This application discloses a cooling module for an X-ray generating device, hereinafter referred to as the cooling module. The cooling module needs to be used in conjunction with the X-ray generating device to cool the X-ray generating device during operation and ensure that the X-ray generating device works normally.

[0035] For details, please refer to Figures 1 to 6 The cooling module has a first cooling cavity 7 and a second cooling cavity 8 arranged at intervals in a first direction. The first cooling cavity 7 and the second cooling cavity 8 respectively install the X-ray tube and the high-voltage generator of the X-ray generating device (not shown in the figure). For example, the first cooling cavity 7 can install the X-ray tube and the second cooling cavity 8 can install the high-voltage generator. The first direction can be the up and down direction. The first cooling cavity 7 can be located above the second cooling cavity 8. That is, during the operation of the X-ray generating device, the X-ray tube can be located above the high-voltage generator. Of course, in other embodiments, the second cooling cavity 8 can be used to install the X-ray tube and the first cooling cavity 7 can be used to install the high-voltage generator. During the operation of the X-ray generating device, the high-voltage generator is located above the X-ray tube.

[0036] The cooling module includes a first fixing member 1 located between a first cooling chamber 7 and a second cooling chamber 8. The first fixing member 1 has a first side surface 11 and a second side surface 12 facing away from each other in a first direction. The first side surface 11 faces the first cooling chamber 7 and forms part of the cavity wall of the first cooling chamber 7, while the second side surface 12 faces the second cooling chamber 8 and forms part of the cavity wall of the second cooling chamber 8. The cooling module has a cooling channel 107 through which the cooling medium passes, including a first cooling channel 13 located within the first fixing member 1. During the operation of the X-ray generating device, the heat generated by the X-ray tube can be transferred to the first fixing member 1 through part of the cavity wall of the first cooling chamber 7, i.e., the first side surface 11. The heat generated by the high-voltage generator can also be transferred through... Part of the cavity wall surface of the second cooling chamber 8, i.e. the second side surface 12, transmits heat to the first fixing member 1. The cooling medium flowing in the first cooling channel 13 of the first fixing member 1 can remove the heat transferred from the X-ray generating device to the first fixing member 1. In this way, the cooling medium flowing in the cooling channel 107 can simultaneously cool the X-ray tube and the high-voltage generator. Compared with the existing air cooling method, water cooling can improve the cooling efficiency of the X-ray generating device. Furthermore, the cooling medium in the cooling channel between the X-ray tube and the high-voltage generator can simultaneously cool both the X-ray tube and the high-voltage generator, which can simplify the arrangement of the cooling channel. In addition, by increasing the flow rate and velocity of the cooling medium in the cooling channel, the heat generated by the X-ray tube and the high-voltage generator can be matched, reducing the probability of the X-ray generating device malfunctioning due to prolonged high-temperature operation.

[0037] In some embodiments, please refer to Figures 1 to 3The cooling module includes a second fixing member 2, which is located above the first fixing member 1 in a first direction and is connected to the first fixing member 1. A first cooling cavity 7 is located between the first fixing member 1 and the second fixing member 2. The second fixing member 2 forms part of the cavity wall of the first cooling cavity 7 on all or part of its side facing the first cooling cavity 7 in the first direction. The cooling channel 107 also includes a second cooling channel 22 located within the second fixing member 2. Thus, a portion of the heat generated by the X-ray tube during operation can be transferred to the second fixing member 2 through its side facing the first cooling cavity 7 in the first direction. The cooling medium flowing in the second cooling channel 22 within the second fixing member 2 can carry away this heat. In this way, the cooling medium in the second cooling channel 22 within the second fixing member 2 can achieve cooling of the X-ray tube, which can improve the cooling efficiency of the X-ray tube and make up for the deficiency of insufficient heat dissipation capacity caused by only the first fixing member 1 dissipating heat from the X-ray tube. Furthermore, the second fixing member 2 is located on the side of the X-ray tube away from the first fixing member 1 in the first direction. At the same time, heat dissipation of the X-ray tube is achieved through the first fixing member 1 and the second fixing member 2, which can ensure uniform heat dissipation in the circumferential direction of the X-ray tube and reduce the probability of the X-ray tube malfunctioning due to excessive local temperature.

[0038] In some embodiments, please refer to Figures 1 to 3 The first cooling cavity 7 extends in a second direction, which is perpendicular to the first direction. The first fixing member 1 and the second fixing member 2 are in contact and connected in the first direction. The first fixing member 1 and the second fixing member 2 enclose the first cooling cavity 7. The first side 11 of the first fixing member 1 facing the first cooling cavity 7 is an arc-shaped surface, and the side of the second fixing member 2 facing the first cooling cavity 7 is also an arc-shaped surface. The two arc-shaped surfaces come together to form the cavity wall of the first cooling cavity 7. The cavity wall is a cylindrical surface for fitting with the outer peripheral surface of the X-ray tube. In this way, the first side 11 of the first fixing member 1 facing the first cooling cavity 7 and the side of the second fixing member 2 facing the first cooling cavity 7 are both in contact with the outer peripheral surface of the X-ray tube, which can increase the heat dissipation area of ​​the X-ray tube and improve the heat dissipation efficiency of the X-ray tube.

[0039] Of course, in other embodiments, a connecting member can also be provided between the first fixing member 1 and the second fixing member 2. The first fixing member 1 is connected to the second fixing member 2 through the connecting member. The connecting member can be in contact with or spaced apart from the outer peripheral surface of the X-ray tube.

[0040] For further information, please continue to refer to [link / reference]. Figures 1 to 3Since the first cooling cavity 7 extends in the second direction, and the extension direction of the first cooling cavity 7 is greater than the cross-sectional dimension of the first cooling cavity 7, that is, greater than the diameter of the first cooling cavity 7, in order to ensure that the cavity wall of the first cooling cavity 7 is as close as possible to the outer peripheral surface of the ray tube during the installation of the ray tube in the first cooling cavity 7, so as to improve the heat transfer efficiency, the first fixing member 1 and the second fixing member 2 are detachably connected by a plurality of first connecting structures 5 arranged at intervals in the second direction. In this way, by adjusting the degree of connection of the first connecting structures 5 at different positions in the second direction, the relative position of the first fixing member 1 and the second fixing member 2 in the first direction can be changed, thereby compensating for the processing errors of the first fixing member 1 and the second fixing member 2, and ensuring that the cavity wall of the first cooling cavity 7 is as close as possible to the outer peripheral surface of the ray tube in all parts of the second direction.

[0041] Specifically, the first connecting structure 5 includes a first connecting bolt 51, which can pass through the second fixing member 2 from top to bottom and engage with the threaded hole on the first fixing member 1 to realize the connection between the first fixing member 1 and the second fixing member 2. The first connecting structure 5 is arranged on both sides of the first cooling cavity 7, and two, three or more first connecting structures 5 can be provided in the second direction. For example, two first connecting structures 5 can be provided at both ends of the first cooling cavity 7 in the second direction. The two first connecting structures 5 are respectively arranged on both sides of the first cooling cavity 7. By changing the locking degree of any first connecting structure 5, the relative position of the first fixing member 1 and the second fixing member 2 can be adjusted to increase the contact area between the cavity wall surface of the first cooling cavity 7 and the X-ray tube.

[0042] Of course, the first connection structure can also be a hook structure. The hook structure includes a hook on the second fixing member 2 and multiple slots on the first fixing member 1. The position of the first fixing member 1 relative to the second fixing member 2 can be changed by changing the position of the slots that cooperate with the hook structure, thereby increasing the contact area between the cavity wall of the first cooling cavity 7 and the ray tube.

[0043] In one embodiment, please refer to Figure 1 Since the second fixing member 2 is located on the upper side of the first fixing member 1, a through hole 21 communicating with the first cooling chamber 7 can be provided on the second fixing member 2. The emitting end of the X-ray tube can extend out from the through hole 21 or the emitting end of the X-ray tube can be aligned with the through hole 21 so that X-rays can be emitted from the through hole 21.

[0044] In some embodiments, please refer to Figures 1 to 3The cooling module also includes a third fixing member 3, which is located below the first fixing member 1 in the first direction and is connected to the first fixing member 1. The second cooling cavity 8 is located between the first fixing member 1 and the third fixing member 3 in the first direction. All or part of the sides of the third fixing member 3 facing the second cooling cavity 8 form part of the cavity side of the second cooling cavity 8. The cooling channel 107 also includes a third cooling channel 31 located within the third fixing member 3. The second cooling cavity 8 is used to install and accommodate the high-voltage generator. A portion of the heat generated by the high-voltage generator during operation can also be transferred to the third fixing member 3 through the side of the third fixing member 3 facing the second cooling cavity 8 in the first direction. 3. The cooling medium flowing in the third cooling channel 31 within the third fixing member 3 can carry away this heat. Thus, the cooling medium in the third cooling channel 31 within the third fixing member 3 can cool the high-voltage generator, thereby improving the cooling efficiency of the high-voltage generator and compensating for the insufficient heat dissipation capacity caused by only using the first fixing member 1 to dissipate heat from the high-voltage generator. Furthermore, the third fixing member 3 is located on the side of the high-voltage generator away from the first fixing member 1 in the first direction. Simultaneously, heat dissipation of the high-voltage generator is achieved through both the first fixing member 1 and the third fixing member 3, which can ensure uniform heat dissipation on the outer side of the high-voltage generator and reduce the probability of the high-voltage generator malfunctioning due to excessively high local temperatures.

[0045] In some embodiments, please continue to refer to Figures 1 to 3 The second cooling chamber 8 also extends in the second direction. The cavity wall of the second cooling chamber 8 is used to fit against the outer side of the high voltage generator. The relative positions of the first fixing member 1 and the third fixing member 3 in the first direction are adjustable.

[0046] Specifically, a portion of the second side 12 of the first fixing member 1 facing the second cooling cavity 8 and the side of the third fixing member 3 facing the second cooling cavity 8 both form the cavity wall surface of the second cooling cavity 8, and both are used to fit against the outer side of the high voltage generator. This can increase the heat dissipation area of ​​the high voltage generator and improve the heat dissipation efficiency of the high voltage generator.

[0047] In one embodiment, the third fixing member can be directly connected to the first fixing member through a second connecting structure. The second connecting structure may include a second connecting bolt. After the second connecting bolt passes through the third fixing member, it engages with the threaded connection of the first fixing member. The relative position of the third fixing member and the first fixing member in the first direction can be changed by changing the tightening degree of the second connecting bolt, so as to compensate for the defect that the cavity wall surface of the second cooling cavity cannot fit well with the outer surface of the high-voltage generator at various points in the second direction due to the machining errors of the first and second fixing members.

[0048] In some embodiments, please refer to Figures 1 to 3The cooling module also includes a support member 4, which is located on the side of the first fixing member 1 away from the first cooling chamber 7 in the first direction. The support member 4 can be a support plate. There are two support members 4, which are fixedly connected to the two ends of the first fixing member 1 in the third direction. The third direction is perpendicular to the first and second directions. The first fixing member 1 can be supported on the ground by the support member 4. The third fixing member 3 is detachably connected between the two support members 4 through the second connecting structure 6. The first fixing member 1, the third fixing member 3 and the two support members 4 enclose and form a second cooling chamber 8. The support member 4 and the high-voltage generator in the second cooling chamber 8 can be arranged at intervals. The high-voltage generator can be cooled by the airflow flowing between the high-voltage generator and the support member 4.

[0049] The first fixing member 1 has a horizontal plate surface on its second side 12 facing the second cooling chamber 8. The third fixing member 3 is a horizontally arranged plate structure. The second connecting structure 6 includes an elongated hole 61 and a second connecting bolt 62 on the support member 4. The side of the third fixing member 3 has a threaded hole that mates with the second connecting bolt 62. The second connecting bolt 62 can pass through the elongated hole 61 and connect to the third fixing member 3 to achieve a detachable connection between the third fixing member 3 and the support member 4. The elongated hole 61 extends in the first direction, and the relative position of the third fixing member 3 and the first fixing member 1 in the first direction can be changed by changing the position of the second connecting bolt 62 in the elongated hole 61. Multiple second connecting structures 6 can be provided, such as two, three or more. The third fixing member 3 is provided with second connecting structures 6 on both sides of the third direction. Multiple second connecting structures 6 located on one side of the third fixing member 3 in the third direction are arranged at intervals in the second direction. For example, second connecting structures 6 can be provided at both ends of the third fixing member 3 in the second direction. The relative position between the third fixing member 3 and the first fixing member 1 at the position of the second connecting structure 6 can be adjusted by adjusting the locking degree of any second connecting structure 6, so as to ensure that the upper side of the third fixing member 3 and the second side 12 of the first fixing member 1 are in contact with the side of the high voltage generator, thereby increasing the contact area between the cavity wall surface of the second cooling cavity 8 and the high voltage generator.

[0050] In some embodiments, cooling channels are provided on the first fixing member 1, the second fixing member 2, and the third fixing member 3. Any two of the three cooling channels are connected, or all three are connected sequentially, so that the cooling medium circulates within the cooling channels of the three fixing members. For example, the first cooling channel 13 can be connected to the second cooling channel 22, or the second cooling channel 22 can be connected to the third cooling channel 31, or the third cooling channel 31 can be connected to the first cooling channel 13, or the first cooling channel 13 can be connected to the third cooling channel 31 sequentially through the second cooling channel 22. This allows the cooling medium to circulate within the cooling channel 107, thereby improving the cooling efficiency of the cooling module for the X-ray generating device.

[0051] In some embodiments, for the cooling channels in the three fixing members, since the first cooling chamber 7 and the second cooling chamber 8 both extend in the second direction, multiple branch channels can be provided in each cooling channel and all of them extend in the second direction. The ends of two adjacent branch channels are connected in the second direction, so that each cooling channel forms an S-shaped reciprocating channel.

[0052] In some embodiments, please refer to Figures 3 to 6 To simplify the structure of each cooling channel and facilitate the processing and fabrication of each fixing component, the first cooling channel 13 on the first fixing component 1 may include multiple first longitudinal channels 131, which are spaced apart in a third direction. For example, depending on the size of the first fixing component 1, there may be two, three, four, or more first longitudinal channels 131. Please refer to [reference needed]. Figure 4 There are four first longitudinal flow channels 131, which are arranged at intervals in a third direction. The first cooling flow channel 13 also includes a first transverse flow channel 132, which is located at the end of the first longitudinal flow channels 131 in a second direction and connects to at least two first longitudinal flow channels 131. Please refer to [reference needed]. Figure 4 In an embodiment where four first longitudinal flow channels 131 are provided, there are two first transverse flow channels 132, which are arranged at intervals in the third direction. Each first transverse flow channel 132 is connected to two first longitudinal flow channels 131. The first fixing member 1 has multiple first external interfaces 133 that communicate with the first longitudinal flow channels 131 and / or the first transverse flow channels 132. For example, the ends of the first longitudinal flow channels 131 that are away from the first transverse flow channels 132 in the second direction all form first external interfaces 133, and the ends of the first transverse flow channels 132 that face the outside of the first fixing member 1 in the third direction also form first external interfaces 133. The first external interfaces 133 can be used to allow external cooling medium to enter or flow out of the first cooling channel, or only the ends of the first longitudinal flow channels 131 form first external interfaces 133. When processing conditions permit, the first transverse flow channels 132 are sealed in the first fixing member 1, or only the ends of the first transverse flow channels 132 form first external interfaces 133, and the first longitudinal flow channels 131 are sealed in the first fixing member 1.

[0053] In some embodiments, for the second cooling channel 22 on the second fixing member 2, please refer to Figure 5 It includes multiple second longitudinal flow channels 221 arranged at intervals in a third direction. The number of second longitudinal flow channels 221 can be set according to the size of the second fixing member 2, such as two, three or four. Figure 5The second fixing member 2 has two second longitudinal flow channels 221, which are arranged on both sides of the through hole 21 and extend in the second direction. The second cooling flow channel 22 also includes a second transverse flow channel 222, which connects the two second longitudinal flow channels 221. Two, three, or more second transverse flow channels 222 can also be provided. The second transverse flow channel 222 is located at one end of the second longitudinal flow channel 221 in the second direction and is used to connect at least two second longitudinal flow channels 221, such as... Figure 5 There is one second transverse flow channel 222, which connects to two second longitudinal flow channels 221. The second fixing member 2 has multiple second external interfaces 223 that communicate with the second longitudinal flow channel 221 and / or the second transverse flow channel 222. For example, the two ends of the second transverse flow channel 222 and the ends of the second longitudinal flow channel 221 that are away from the second transverse flow channel 222 in the second direction both form second external interfaces 223, or only the end of one of the second transverse flow channel 222 and the second longitudinal flow channel 221 forms a second external interface 223, and the other is sealed in the second fixing member 2. The second external interface 223 is used to allow external cooling medium to flow into the second cooling channel or to allow cooling medium in the second cooling flow channel 22 to flow out.

[0054] In some embodiments, please refer to Figure 6 The structure of the third cooling channel 31 on the third fixing member 3 is the same as that of the second cooling channel 22. The third cooling channel 31 includes a plurality of third longitudinal channels 311 arranged at intervals in a third direction. The number of third longitudinal channels 311 can be set according to the size of the third fixing member 3, such as two, three or four. Figure 6 The third fixing member 3 has two third longitudinal flow channels 311, and both second longitudinal flow channels 221 extend in the second direction; the third cooling flow channel 31 also includes a third transverse flow channel 312, which connects the two third longitudinal flow channels 311. Two, three, or more third transverse flow channels 312 can also be provided. The third transverse flow channel 312 is located at one end of the third longitudinal flow channel 311 in the second direction and is used to connect at least two third longitudinal flow channels 311, such as... Figure 6 There is one third transverse flow channel 312, which connects to two third longitudinal flow channels 311. The third fixing member 3 has multiple third external interfaces 313 that communicate with the third longitudinal flow channel 311 and / or the third transverse flow channel 312. For example, the two ends of the third transverse flow channel 312 and the ends of the third longitudinal flow channel 311 away from the third transverse flow channel 312 in the second direction are all formed with third external interfaces 313, or only the end of one of the third transverse flow channel 312 and the third longitudinal flow channel 311 is formed with a third external interface 313, and the other is blocked in the third fixing member 3. The third external interface 313 is used to allow external cooling medium to flow into the third cooling channel or to allow cooling medium in the third cooling flow channel 31 to flow out.

[0055] This application also discloses a temperature control system for an X-ray generating device. Please refer to... Figure 7 The device includes a cooling module for an X-ray generating apparatus as described in any of the above embodiments, and further includes a flow control valve 106, a first temperature sensor 102, a second temperature sensor 104, and a controller 103. The first temperature sensor 102, the second temperature sensor 104, and the flow control valve 106 are all electrically connected to the controller 103. The first temperature sensor 102 can be installed on the first fixing member 1, the second fixing member 2, or the X-ray tube 101. The first temperature sensor 102 is used to detect the temperature of the X-ray tube 101 and transmit the temperature signal of the X-ray tube 101 to the controller 103. The second temperature sensor 104 can be installed on the first fixing member 1, the third fixing member 3, or the high-voltage generator 105. The second temperature sensor 104 is used to detect the temperature of the high-voltage generator 105 and transmit the temperature signal of the high-voltage generator 105 to the controller.

[0056] The flow control valve 106 is connected to the cooling medium delivery pipeline that communicates with the cooling channel 107. The controller 103 can control the opening of the flow control valve 106 according to the received temperature of the X-ray tube 101 and the high-pressure generator 105. When the temperature of the X-ray tube 101 and the high-pressure generator 105 is higher than the optimal operating temperature, the flow control valve 106 can be opened to increase the flow of the cooling medium in the cooling channel 107 and accelerate the heat dissipation of the X-ray generating device by the cooling module. When the temperature of the X-ray tube 101 and the high-pressure generator 105 is lower than the optimal operating temperature, the flow control valve 106 can be closed to reduce the flow of the cooling medium in the cooling channel and reduce the heat dissipation of the X-ray generating device by the cooling module. This ensures that the X-ray generating device is kept at the optimal operating temperature and that the X-ray generating device works normally.

[0057] In one embodiment, the controller 103 is a PID controller (Proportion Integration Differential controller). Using a PID controller can more accurately control the temperature of both the X-ray tube 101 and the high-voltage generator 105 within the optimal operating temperature range, making their temperatures more stable.

[0058] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
