[0040] Please see Figure 1 , Figure 2 and Figure 3 This application provides a CT detector 10. The CT detector includes multiple CT detector modules 300. The CT detector 10 also includes a CT detector mounting housing 100 and multiple mounting brackets 200. The CT detector mounting housing 100 surrounds and forms a receiving cavity 130. The CT detector mounting housing 100 is provided with a first air duct 140. The multiple mounting brackets 200 are used to mount the CT detector modules 300. The multiple mounting brackets 200 are disposed within the receiving cavity 130. The mounting brackets 200 are provided with a second air duct 210. The first air duct 140 and the second air duct 210 are connected.
[0041] The shape of the CT detector mounting housing 100 can be customized as needed. The CT detector mounting housing 100 can be a cubic structure, a cylindrical structure, an arc-shaped structure, etc. The CT detector mounting housing 100 can be a single, integrally formed structure. The CT detector mounting housing 100 can be a structure composed of multiple sub-housings joined together. The first air duct 140 can be disposed within the receiving cavity 130. The first air duct 140 can also be disposed on the surface of the CT detector mounting housing 100. The first air duct 140 can be formed by a portion of the structure of the CT detector mounting housing 100. That is, the first air duct 140 can be integrally formed with the CT detector mounting housing 100. The first air duct 140 can also be mounted on the CT detector mounting housing 100 as a separate component. The shape and size of the mounting bracket 200 can be adapted to the detector 300. Multiple mounting brackets 200 can be arranged side-by-side. Therefore, the detectors 300 mounted on the mounting brackets 200 can also be arranged side-by-side, saving space.
[0042] The second air duct 210 can be a separate component of the mounting bracket 200, or it can be formed by a portion of the structure of the mounting bracket 200. Each mounting bracket 200 has one second air duct 210. Multiple second air ducts 210 can communicate with the first air duct 140. The first air duct 140 can be used to introduce air. Air can enter the second air duct 210 through the first air duct 140. Within each mounting bracket 200, the second air duct 210 can remove heat. The heat emitted by the detector 300 during operation can be transferred to the second air duct 210 through the mounting bracket 200. Therefore, the temperature of the detector 300 is maintained at a low level. It can be understood that since each mounting bracket 200 has a second air duct 210, the heat emitted by the detector 300 mounted on each mounting bracket 200 can be quickly and instantly discharged through the second air duct 210. Therefore, multiple mounting brackets 200 can be arranged closely side by side to improve integration, save space, and reduce volume. Meanwhile, the parallel arrangement of multiple mounting brackets 200 also provides good heat dissipation, ensuring the normal operation of the detector 300.
[0043] The detector 300 can be a CT detector. The detector 300 emits X-rays that pass through the human body and converts the received light signal into an electrical signal. The detector 300 can collect data after the X-rays pass through human tissue, providing a basis for reconstructing images of the human tissue. The stability of the output signal of the detector 300 is highly dependent on temperature; therefore, ensuring the temperature stability of the detector 300 is crucial to guaranteeing its performance.
[0044] The CT detector 10 provided in this embodiment includes a CT detector mounting housing 100 and a plurality of mounting brackets 200. The CT detector mounting housing 100 surrounds and forms a receiving cavity 130. The CT detector mounting housing 100 is provided with a first air duct 140. The plurality of mounting brackets 200 are used to mount a detector 300. The plurality of mounting brackets 200 are disposed in the receiving cavity 130. The mounting brackets 200 are provided with a second air duct 210. The first air duct 140 and the second air duct 210 are connected. When the detector 300 is mounted on the mounting bracket 200, the heat emitted by the detector 300 during operation can be conducted to the mounting bracket 200. The mounting bracket 200 can transfer the heat to the second air duct 210. The first air duct 140 can introduce air into the second air duct. The air can carry away the heat in the second air duct 210, thus preventing heat from accumulating in the detector 300 and ensuring that the temperature of the detector 300 is maintained at a low level during operation.
[0045] In one embodiment, the CT detector mounting housing 100 includes a first housing 110 and a second housing 120. A plurality of mounting brackets 200 are disposed in the first housing 110. The second housing 120 and the first housing 110 surround each other to form the receiving cavity 130. A first air duct 140 is disposed in the second housing 120. The inner wall of the first housing 110 may have a mounting area. The mounting area may have a fixing structure such as a mounting slot. The mounting slots may be arranged side-by-side. One mounting bracket 200 can be detachably installed in each mounting slot. The second housing 120 can be detachably connected to the first housing 110. Therefore, it is convenient to replace and repair the internal parts of the heat exchange structure of the detector 300. The outer or inner wall of the second housing 120 may form the first air duct 140. When the first housing 110 and the second housing 120 are engaged, the outlet of the first air duct 140 may be opposite to the inlet of the second air duct 120. Therefore, when air is blown into the inlet of the first air duct 140, the air can enter the second air duct 210 through the first air duct 140.
[0046] Please see Figure 4 In one embodiment, the CT detector 10 further includes a plurality of fans 240. The plurality of fans 240 are spaced apart from the second housing 120. The first air duct 140 includes a plurality of first sub-air ducts 142. The plurality of first sub-air ducts 142 and the plurality of fans 240 are connected in a one-to-one correspondence. Each first sub-air duct 142 is connected to at least one second air duct 210.
[0047] The fan 240 can be any type of fan, such as an axial fan or a centrifugal fan. The fan 240 increases the airflow velocity. The fan 240 can blow outside air into the first air duct 140. In one embodiment, a baffle can be provided in the first air duct 140. The baffle can divide the first air duct 140 into several first sub-air ducts 142. Multiple fans 240 can be connected to multiple first sub-air ducts 142 in a one-to-one correspondence. Each first sub-air duct 142 can be connected to at least one second air duct 210. It is understood that when the mounting brackets 200 are arranged side-by-side, the heat dissipation capacity of the detector 300 on the mounting bracket 200 located in the middle of the mounting area will be worse than that of the detector 300 on the mounting brackets 200 surrounding the mounting area. Multiple first sub-air ducts 142 can correspond to the second air ducts 210 on the mounting brackets 200 in different areas of the mounting area. That is, different fans 240 can correspond to the second air ducts 210 of the mounting brackets 200 at different positions in the installation area. The rotational speed of the fans 240 can be adjusted as needed. It can be understood that the rotational speed of the fans 240 corresponding to the second air ducts 210 located in the middle of the installation area can be appropriately greater than the rotational speed of the fans 240 in the second air ducts 210 located around the perimeter of the installation area. Therefore, the heat dissipation capacity of the detectors 300 at different positions in the installation area can be made more consistent.
[0048] In one embodiment, the second housing 120 is further provided with a plurality of air guide channels 150. Each of the plurality of air guide channels 150 corresponds one-to-one with a plurality of the fans 240. Each fan 240 is connected to a first sub-duct 142 through one of the air guide channels 150. The two ends of the air guide channel 150 are respectively connected to the outlet of the fan 240 and the inlet of the first sub-duct 142. The path of the air guide channel 150 can be configured as needed. The air guide channel 150 can be disposed on the inner wall or the outer wall of the second housing 120. In one embodiment, both the fans 240 and the air guide channels 150 are disposed on the outer wall of the second housing 120. The second housing 120 can be stamped to form a mounting cavity for the fans 240. The mounting cavity protrudes from the outer wall of the second housing 120. The air guide channels 150 can also protrude from the outer wall of the second housing 120. The air guide channels 150 communicate with the mounting cavity.
[0049] In one embodiment, multiple mounting brackets 200 may be disposed on the top of the first housing 110. That is, the second air duct 210 may be disposed on the top of the first housing 110. The first air duct 140 may be disposed on the top of the second housing 120. When the first housing 110 and the second housing 120 are engaged to form the receiving cavity 130, the second air duct 210 and the first air duct 140 can be positioned opposite each other to achieve communication. The fan 240 may be disposed on the bottom of the second housing 120. The air guide channel 150 may be disposed between the top and bottom of the second housing 120. Therefore, the surface area of the second housing 120 can be fully utilized.
[0050] In one embodiment, the second housing 120 may include a base plate 128 and a side plate 126. The base plate 128 is connected to the side plate 126. The air guide channel 150, the first air duct 140, and the fan 240 are disposed on the side plate 126. The base plate 128 may include multiple splicing plates. The multiple splicing plates may be connected end to end. The multiple splicing plates may be at a certain angle. Therefore, the shape of the second housing 120 can be flexibly adjusted.
[0051] In one embodiment, the surface of the first housing 110 may also have a vent 129. The detector 300 may be disposed opposite to the vent 129, meaning the detector 300 can be exposed through the vent 129. Therefore, the heat generated by the detector 300 can diffuse outward through the vent 129. The heat carried away by the air in the second air duct 210 can also diffuse outward through the vent 129. In one embodiment, the vent 129 may be rectangular, circular, or other polygonal structures.
[0052] In one embodiment, the cross-section of the air guide duct 150 can be rectangular or circular. The cross-section of the first sub-duct 142 can be rectangular or circular.
[0053] In one embodiment, the first housing 110 and the second housing 120 are detachably connected. That is, the first housing 110 and the second housing 120 can form a receiving cavity 130 through a plug-in structure. Alternatively, the first housing 110 and the second housing 120 can form the receiving cavity 130 through a bolted connection or a threaded engagement. The detachable connection of the first housing 110 and the second housing 120 facilitates disassembly, cleaning, and replacement of parts within the receiving cavity 130.
[0054] Please see Figure 5In one embodiment, the first housing 110 has a guide rail 112. The second housing 120 is provided with a slide rail 122 that cooperates with the guide rail 112. The first housing 110 and the second housing 120 are detachably connected via the guide rail 112 and the slide rail 122. The slide rail 122 can slide under the guidance of the guide rail 112. That is, when the slide rail 122 slides to the bottom of the guide rail 112, the first housing 110 and the second housing 120 can be engaged to form the receiving cavity 130. When the slide rail 122 is pulled out from the slide rail, the first housing 110 and the second housing 120 separate, making installation and disassembly convenient.
[0055] In one embodiment, a guide rail 112 is provided on each of the opposite sides of the top of the first housing 110. Two slide rails 122 are provided on each of the opposite sides of the top of the second housing 120. The two slide rails 122 can respectively engage with the two guide rails 112. This structure can evenly distribute the compressive stress between the first housing 110 and the second housing 120, preventing damage to the first housing 110 and the second housing 120 due to excessive stress.
[0056] In one embodiment, the air inlets of the second air ducts 210 of the plurality of mounting brackets 200 are arranged in an arc shape side by side. The air outlet surface of the first air duct 140 has an arc shape. The air inlets and air outlet surfaces of the first air ducts 140 of the plurality of mounting brackets 200 are arranged opposite to each other. It can be understood that when the CT detector 10 is installed on the CT device 20, the CT detector 10 can be arranged around the cavity of the CT device 20. The cavity is used to accommodate a patient. Since the cross-section of the cavity can be circular, the CT detector 10 as a whole can also have an arc shape to facilitate its arrangement around the cavity. The top of the first housing 110 and the top of the second housing 120 can face the cavity. Therefore, the tops of the first housing 110 and the second housing 120 can have an arc shape. The plurality of mounting brackets 200 are located on the top of the first housing 110. Therefore, the mounting brackets 200 can also be arranged in an arc-shaped linear arrangement. In other words, the second air ducts 210 disposed on the mounting bracket 200 can also be arranged in an arc-shaped linear pattern. The air inlets of the multiple second air ducts 210 can face the same side and be arranged in an arc-shaped linear pattern. The first air duct 140 can be disposed on the top of the second housing 120. When the first housing 110 is fastened to the second housing 120, the air outlet of the first air duct 140 is directly opposite the air inlets of the multiple second air ducts 210. That is, the air outlet from the first air duct 140 can be dispersed into the multiple second air ducts 210.
[0057] Please see Figure 6 and Figure 7 In one embodiment, the mounting bracket 200 has a first surface 212 and a second surface 214 facing each other. The first surface 212 is used to mount the detector 300. The second surface 214 is provided with a heat sink 220 and a second air duct 210. The heat sink 220 is located in the second air duct 210. The mounting bracket 200 can be a plate-like structure. The width of the first surface 212 can be slightly larger than the width of the detector 300 to facilitate the mounting of the detector 300. The first surface 212 can be provided with two protrusions 213 spaced apart. The detector 300 can be mounted between the two protrusions 213. On the second surface 214, the portion directly opposite the detector 300 can be the heat sink 220. In one embodiment, the orthographic projection of the heat sink 220 on the first surface 212 can completely cover the detector 300. That is, the projection of the heat sink 220 on the first surface 212 is larger than the projection of the detector 300 on the first surface 212. Therefore, the heat dissipation area of the heat sink 220 is larger, which can improve the heat dissipation efficiency. The second surface 214 can form the second air duct 210. The heat sink 220 can be formed in the path of the second air duct 210. That is, the air entering the second air duct 210 from the first air duct 140 can blow onto the heat sink 220, which facilitates the removal of heat from the heat sink 220.
[0058] Please see Figure 8 and Figure 9 In one embodiment, the heat sink 220 can be a plurality of heat sink fins arranged side by side. The heat sink fins can have the same shape. The height of the heat sink fins can also be different corresponding to different positions of the detector 300, that is, the heat dissipation area of the heat sink fins can be different. For the parts of the detector 300 with good heat dissipation, the heat dissipation area of the heat sink fins can be smaller to save space. For the parts of the detector 300 with poor heat dissipation, the area of the heat sink fins can be increased, that is, the height of the heat sink fins can be increased. Please refer to [link to previous text]. Figure 8 On one side of the mounting bracket 200, the height of the heat dissipation fins gradually decreases. That is, in the portion of the heat dissipation fins where the height decreases, the corresponding heat generation of the detector 300 is lower. Conversely, in the portion of the heat dissipation fins where the height increases, the corresponding heat generation of the detector 300 is higher. The height of the corresponding heat dissipation fins can be varied according to the heat dissipation capacity of different parts of the detector 300. The fins are processed into different shapes to meet the temperature gradient requirements of the detection module along its length.
[0059] In one embodiment, the temperature of the detector 300 can be controlled between 33°C and 37°C by controlling the area of the heat dissipation fins. Within this temperature range, the temperature range of each detector 300 can be kept as uniform as possible.
[0060] In one embodiment, the CT detector 10 further includes a circuit board 230. The circuit board 230 is disposed on the side of the mounting bracket 200 near the second surface 214. A second air duct 210 is provided at one end of the circuit board 230. The circuit board 230 can be a printed circuit board (PCB). The circuit board 230 can convert the digital signals generated by the chip of the detector 300 into raw data and transmit it to the next stage. The second air duct 210 is disposed adjacent to the circuit board 230. Therefore, the second air duct 210 can also remove the heat generated by the circuit board 230. Maintaining the temperature W of the circuit board 230 at a low level can extend the service life of the circuit board 230.
[0061] In one embodiment, a support plate 240 is provided at one end of the circuit board 230. Ventilation pipes 216 are respectively provided on both sides of the support plate 240. The second air duct 210 includes the ventilation pipes 216. The heat sink 220 is disposed between the two ventilation pipes 216. One end of the circuit board 230 can be fixed to the support plate 240. The ventilation pipes 216 can be integrally formed with the support plate 240. One ventilation pipe 216 can serve as the inlet of the second air duct 210. The other ventilation pipe 216 can serve as the outlet of the second air duct 210. The heat sink 220 can be placed between the two ventilation pipes 216. When the mounting bracket 200 cooperates with the support plate 240, both ends of the mounting bracket 200 can overlap the surfaces of the two ventilation pipes 216 away from the circuit board 230. The heat sink 220, located in the middle of the mounting bracket 200, is precisely positioned between the two ventilation pipes 216. Therefore, when air passes between the two ventilation ducts 216, it passes through the heat sink 220 and carries away the heat from the heat sink 220, allowing the CT detector module to operate normally. In one embodiment, the cross-section of the two ventilation ducts 216 can be a rectangular structure. Therefore, the side of the ventilation duct 216 away from the circuit board 230 is flat to facilitate the placement of the mounting bracket 200.
[0062] In one embodiment, the support plate 240 can be the side of a rectangular tube. Three sides can be removed from the middle of the rectangular tube to create a receiving space for the heat sink 220. The remaining portions at both ends of the rectangular tube can then form the ventilation duct 216.
[0063] In one embodiment, the surface of the ventilation duct 216 is provided with a through hole. The surface of the mounting bracket 200 is also provided with a through hole. The mounting bracket 200 is fixedly connected to the ventilation duct 216 through the through hole.
[0064] Please see Figure 10 This application also provides a CT device 20. The CT device 20 includes the aforementioned CT detector 10. The CT detector 10 further includes the CT detector module 300. The CT detector module 300 is disposed on the mounting bracket 200. The CT device 20 can be a computed tomography (CT) scanner. The CT scanner can have a support frame 400. The CT detector 10 can be disposed on the frame 400.
