Referring to fig. 1, 2 and 3, an embodiment of the present application provides a CT detector 10. The CT detector includes a plurality of CT detector modules 300. The CT detector 10 also includes a CT detector mounting housing 100 and a plurality of mounting brackets 200. The CT detector mounting housing 100 encloses a receiving cavity 130. The CT detector mounting case 100 is provided with a first air duct 140. A plurality of the mounting brackets 200 are used to mount the CT detector modules 300. A plurality of the mounting brackets 200 are disposed in the accommodating chamber 130. The mounting bracket 200 is provided with a second air duct 210. The first air duct 140 communicates with the second air duct 210.

The CT detector mounting housing 100 may be shaped as desired. The CT detector mounting case 100 may have a cubic structure, a cylindrical structure, an arc structure, or the like. The CT detector mounting housing 100 may be an integrally formed unitary structure. The CT detector mounting housing 100 may be a structure formed by splicing a plurality of sub-housings. The first air duct 140 may be disposed in the accommodating chamber 130. The first air duct 140 may also be disposed on a surface of the CT detector mounting housing 100. The first air duct 140 may be formed by surrounding a portion of the structure of the CT detector mounting case 100. That is, the first air duct 140 may be integrally formed with the CT detector mounting housing 100. The first air duct 140 may also be mounted to the CT detector mounting housing 100 as a separate component. The mounting bracket 200 may be shaped and sized to fit the probe 300. A plurality of the mounting brackets 200 may be arranged side by side. Therefore, the probes 300 disposed on the mounting bracket 200 are also disposed side by side, which can save space.

The second air duct 210 may be a separate component disposed on the mounting bracket 200, or may be formed by surrounding a portion of the mounting bracket 200. One second air duct 210 is provided for each mounting bracket 200. A plurality of the second air paths 210 may communicate with the first air path 140. The first air duct 140 may be used to introduce air. Air may enter the second air duct 210 through the first air duct 140. Within each of the mounting brackets 200, the second air duct 210 may function to carry away heat. The heat emitted by the detector 300 during operation may be transferred to the second air duct 210 through the mounting bracket 200. The temperature of the probe 300 is maintained at a low level. It is understood that one second air duct 210 is provided in each of the mounting brackets 200. Therefore, the heat emitted from the detector 300 disposed on each of the mounting brackets 200 can be quickly conducted out through the second air duct 210 in real time. Therefore, a plurality of the mounting brackets 200 can be arranged closely side by side to improve the integration level and achieve the purposes of saving space and reducing volume. Meanwhile, the plurality of mounting brackets 200 are arranged in parallel, so that a good heat dissipation effect is achieved, and the detector 300 can work normally.

The detector 300 may be a CT detector. The detector 300 may emit X-rays for passing through a human body and convert a received optical signal into an electrical signal. The detector 300 may collect data after X-rays pass through human tissue, and provide a basis for reconstructing image information of human tissue. The stability of the output signal of the detector 300 has a large temperature relationship, and therefore, ensuring the stability of the temperature of the detector 300 is critical to ensuring the performance of the detector 300.

The CT detector 10 provided by the embodiment of the present application includes a CT detector mounting housing 100 and a plurality of mounting brackets 200. The CT detector mounting housing 100 encloses a receiving cavity 130. The CT detector mounting case 100 is provided with a first air duct 140. A plurality of the mounting brackets 200 are used to mount the probe 300. A plurality of the mounting brackets 200 are disposed in the accommodating chamber 130. The mounting bracket 200 is provided with a second air duct 210. The first air duct 140 communicates with the second air duct 210. When the probe 300 is mounted on the mounting bracket 200, heat emitted from the probe 300 during operation may be conducted to the mounting bracket 200. The mounting bracket 200 may transfer heat to the second air duct 210. The first air duct 140 may introduce air into the second air duct. The air can remove heat from the second air duct 210, so that heat can be prevented from accumulating in the detector 300, and the temperature of the detector 300 can be kept at a low level during operation.

In one embodiment, the CT detector mounting housing 100 includes a first housing 110 and a second housing 120. A plurality of the mounting brackets 200 are disposed on the first housing 110. The second housing 120 and the first housing 110 enclose to form the accommodating chamber 130. The first air duct 140 is disposed on the second housing 120. The inner wall of the first housing 110 may be provided with a mounting region. The mounting area can be provided with fixing structures such as mounting grooves. The mounting slots may be arranged side by side. One of the mounting brackets 200 may be detachably mounted in each of the mounting slots. The second housing 120 may be detachably coupled to the first housing 110. It is possible to facilitate replacement and maintenance of the internal parts of the heat exchange structure of the probe 300. The outer wall or the inner wall of the second housing 120 may form the first air path 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 210. Accordingly, when air is blown into the inlet of the first air path 140, the air may enter the second air path 210 through the first air path 140.

Referring to fig. 4, in one embodiment, the CT detector 10 further includes a plurality of fans 240. The fans 240 are disposed at intervals in the second housing 120. The first air duct 140 includes a plurality of first sub-air ducts 142. The first sub-air ducts 142 are in one-to-one correspondence with the fans 240. Each of the first sub-air paths 142 is in communication with at least one of the second air paths 210.

The fan 240 may be an axial flow fan, a centrifugal fan, or other fans. The air flow rate can be increased by the fan 240. The fan 240 may blow external air into the first air duct 140. In one embodiment, a partition may be provided in the first air duct 140. The first air duct 140 may be divided into a plurality of first sub-air ducts 142 by the partition. The fans 240 may be in one-to-one correspondence with the first sub-air ducts 142. Each of the first sub-air paths 142 may be in communication with at least one of the second air paths 210. It will be appreciated that when the mounting brackets 200 are positioned side-by-side, the heat dissipation capability of the probes 300 on the mounting brackets 200 in the middle of the mounting area may be less than the heat dissipation capability of the probes 300 on the mounting brackets 200 around the mounting area. The plurality of first sub-air ducts 142 may correspond to the second air ducts 210 on the mounting bracket 200 in different areas of the mounting area. That is, different fans 240 may correspond to different positions of the second air duct 210 of the mounting bracket 200 in the mounting area. The rotational speed of the fan 240 can be adjusted as desired. It is understood that the rotation speed of the fan 240 corresponding to the second wind tunnel 210 located at the middle of the installation area may be appropriately greater than the rotation speed of the fan 240 of the second wind tunnel 210 located at the periphery of the installation area. The heat dissipation capability of the detector 300 at different positions of the mounting area can be made uniform.

In one embodiment, the second housing 120 is further provided with a plurality of air guide channels 150. The plurality of air guide channels 150 are arranged in one-to-one correspondence with the plurality of fans 240. Each of the fans 240 is communicated with one of the first sub-air ducts 142 through one of the air guide passages 150. Both ends of the air guiding channel 150 are respectively connected to the outlet of the fan 240 and the inlet of the first sub-air duct 142. The path of the wind guide channel 150 may be set as required. The air guide passage 150 may be disposed on an inner wall or an outer wall of the second housing 120. In one embodiment, the fan 240 and the air guide passage 150 are both disposed on an outer wall of the second housing 120. The second housing 120 may be formed by punching to form a mounting cavity of the blower 240. The mounting cavity protrudes from an outer wall of the second housing 120. The air guide passage 150 may protrude from an outer wall of the second casing 120. The air guide channel 150 is communicated with the installation cavity.

In one embodiment, a plurality of the mounting brackets 200 may be disposed on the top of the first housing 110. That is, the second air duct 210 may be disposed at 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 relatively buckled to form the accommodating cavity 130, the second air duct 210 and the first air duct 140 can be relatively arranged to achieve the purpose of communication. The blower 240 may be disposed at the bottom of the second housing 120. The air guide passage 150 may be disposed between the top and bottom of the second housing 120. The surface area of the second housing 120 can be fully utilized.

In one embodiment, the second housing 120 may include a bottom panel 128 and side panels 126. The bottom panel 128 is connected to the side panel 126. The air guide channel 150, the first air duct 140 and the fan 240 are disposed on the side plate 126. The bottom plate 128 may include a plurality of splice plates. The splice plates can be connected end to end in sequence. A certain angle can be formed between the splicing plates. The shape of the second housing 120 can be flexibly adjusted.

In one embodiment, the surface of the first housing 110 may also have vents 129. The detector 300 may be disposed opposite the vent 129. I.e., the detector 300 may be exposed from the vent 129. Heat generated by the detector 300 can be diffused outward from the vent 129. The heat carried away by the air in the second air duct 210 can also be diffused outward through the ventilation opening 129. In one embodiment, the vent 129 may be rectangular, circular, or other polygonal configuration.

In one embodiment, the cross section of the wind guide channel 150 may be rectangular or circular. The cross-section of the first sub-air duct 142 may be rectangular or circular.

In one embodiment, the first housing 110 and the second housing 120 are removably coupled. That is, the first housing 110 and the second housing 120 may form the receiving cavity 130 through a plug structure. The first housing 110 and the second housing 120 may also form the accommodating chamber 130 by means of bolt connection or screw thread fit. The detachable connection of the first housing 110 and the second housing 120 can facilitate the removal, cleaning and replacement of parts in the receiving chamber 130.

Referring to fig. 5, in 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 by 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 along the bottom of the guide rail 112, the first housing 110 and the second housing 120 can be relatively buckled to form the receiving cavity 130. When the sliding rail 122 is pulled out of the sliding way, the first housing 110 and the second housing 120 are separated, and the installation and the disassembly are convenient.

In one embodiment, the guide rails 112 are disposed on two opposite sides of the top of the first housing 110. Two sliding rails 122 are respectively disposed on two opposite sides of the top of the second housing 120. The two slide rails 122 may be respectively engaged with the two guide rails 112. This structure can equalize the compressive stress between the first casing 110 and the second casing 120, and prevent the first casing 110 and the second casing 120 from being damaged due to excessive stress.

In one embodiment, the air inlets of the second air ducts 210 of a plurality of the mounting brackets 200 are arranged in parallel in an arc shape. The air outlet surface of the first air duct 140 is of an arc-shaped structure. The air inlet of the first air duct 140 of the plurality of mounting brackets 200 is opposite to the air outlet surface of the first air duct 140. It is understood that when the CT detector 10 is mounted to the CT device 20, the CT detector 10 may be disposed around a bore of the CT device 20. The bore is for receiving a patient therein. Since the cross-section of the bore may be circular. The entirety of the CT detector 10 may also be curved so as to be disposed around the bore. The top of the first housing 110 and the top of the second housing 120 may face the cavity. Therefore, the top of the first housing 110 and the second housing 120 may be an arc-shaped mechanism. A plurality of the mounting brackets 200 are located at the top of the first housing 110. Thus, the mounting brackets 200 may also be arranged linearly in an arc. That is, the second air ducts 210 disposed on the mounting bracket 200 may also be arranged in an arc-shaped linear manner. The air inlets of the second air ducts 210 may face the same side and be arranged in an arc shape. The first air duct 140 may 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 just opposite to the air inlets of the plurality of second air ducts 210. That is, the outlet air from the outlet of the first air duct 140 may be dispersed into the plurality of second air ducts 210.

Referring to fig. 6 and 7, in one embodiment, the mounting bracket 200 has first and second opposing

surfaces

212, 214. The first surface 212 is used to mount the probe 300. The second surface 214 is provided with a heat sink 220 and the second air duct 210. The heat sink 220 is located in the second air duct 210. The mounting bracket 200 may be a plate-like structure. The width of the first surface 212 may be slightly larger than the width of the probe 300 to facilitate mounting of the probe 300. The first surface 212 may be spaced apart by two protrusions 213. The probe 300 may be mounted between the two bosses 213. At the second surface 214, a portion facing the detector 300 may be the heat dissipation member 220. In one embodiment, the orthographic projection of the heat dissipation element 220 on the first surface 212 may completely cover the detector 300. I.e. 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 dissipation member 220 is larger, and the heat dissipation efficiency can be improved. The second surface 214 may form the second air chute 210. The heat sink 220 may be formed in the path of the second air duct 210. That is, the wind entering the second wind tunnel 210 from the first wind tunnel 140 may blow to the heat sink 220, so as to take away the heat in the heat sink 220.

Referring to fig. 8 and 9, in an embodiment, the heat dissipation member 220 may be a plurality of heat dissipation fins arranged in parallel. The heat radiating fins may be identical in shape. The heights of the heat dissipation fins may also be different corresponding to different positions of the detector 300, that is, the heat dissipation areas of the heat dissipation fins may be different. For the part of the detector 300 with better heat dissipation, the heat dissipation area of the heat dissipation fin can be smaller to save space. For the portion of the detector 300 that does not radiate heat well, the area of the heat radiating fins may be increased, that is, the height of the heat radiating fins may be increased. Referring to fig. 8, the height of the heat dissipating fins is gradually reduced at one side of the mounting bracket 200. That is, in the portion where the height of the heat dissipation fin is reduced, the amount of heat generation of the corresponding detector 300 is low. And the heat generation amount of the corresponding detector 300 is higher at the portion where the height of the heat dissipation fin is higher. The heights of the corresponding heat dissipation fins can be different according to the heat dissipation capability of different parts of the detector 300. . The fins are processed into different shapes so as to meet the temperature gradient requirement of the detection module of the detection assembly in the length direction.

In one embodiment, the temperature of the detector 300 can be controlled between 33 ℃ and 37 ℃ by controlling the area of the heat dissipation fins. In the temperature space, the temperature area of each detector 300 can be controlled to be consistent as much as possible.

In one embodiment, the CT detector 10 further includes a circuit board 230. The circuit board 230 is disposed on a side of the mounting bracket 200 adjacent to the second surface 214. One end of the circuit board 230 is provided with the second air duct 210. The circuit board 230 may be a printed circuit board 230 (PCB). The circuit board 230 may convert a digital signal generated from a chip of the probe 300 into Raw Data (Raw Data) and transfer it to a next stage. The second air duct 210 is disposed adjacent to the circuit board 230. Therefore, the second air duct 210 can also take away the heat generated by the circuit board 230. Maintaining the temperature W of the circuit board 230 at a low level may extend the service life of the circuit board 230.

In one embodiment, one end of the circuit board 230 is provided with a support plate 240. The ventilation pipes 216 are respectively disposed at both sides of the support plate 240. The second air duct 210 includes the air duct 216. The heat sink 220 is disposed between the two ventilation pipes 216. One end of the circuit board 230 may be fixed to the support plate 240. The vent tube 216 may be integrally formed with the support plate 240. One of the ventilation ducts 216 may serve as an inlet of the second air duct 210. Another of the ventilation pipes 216 may serve as an outlet of the second wind tunnel 210. The heat sink 220 may be placed in a position between the two ventilation tubes 216. When the mounting bracket 200 is engaged with the supporting plate 240, both ends of the mounting bracket 200 may be overlapped on the surfaces of the two air tubes 216 away from the circuit board 230. The heat radiating member 220 located at the middle of the mounting bracket 200 is located just between the two ventilation pipes 216. Therefore, when wind passes between the two ventilation tubes 216, the wind passes through the heat dissipation member 220 and carries away heat in the heat dissipation member 220, so that the CT detector module normally operates in one embodiment, the cross section of the two ventilation tubes 216 may be a rectangular structure. Thus, the side of the vent tube 216 remote from the circuit board 230 is planar to facilitate placement of the mounting bracket 200.

In one embodiment, the support plate 240 may be a side of a rectangular tube. An accommodation space may be formed by removing three sides from the middle of the rectangular tube to accommodate the heat sink 220. The remaining portions of the rectangular tube at both ends may constitute the ventilation tube 216.
