[0043] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0044] In the field of medical equipment technology, CT machines have been widely used in medical institutions and assist doctors in performing imaging examinations on patients. Usually, a CT machine includes a frame and components such as an X-ray tube and a detector installed on the frame. As the most core component in a CT system, the main function of the detector is data acquisition. The scintillator (a component that converts X-rays into visible light), PD (photodiode) and AD converter inside the detector not only have high operating temperature requirements, but also generate a lot of heat during operation. If the heat cannot be discharged in time, the operating temperature of the above devices will rise, affecting the stability of data acquisition and ultimately affecting the image quality. Therefore, it is necessary to carry out effective heat dissipation design for the detector to ensure that the detector works at a relatively stable temperature.

[0045] In related technologies, the heat dissipation design of detectors mainly includes two methods: air cooling and water cooling. Since the production and maintenance costs of water cooling are too high, it is rarely used. Therefore, air cooling is currently the mainstream heat dissipation method for detectors.

[0046] The more common detector heat dissipation design is shown in publication numbers CN110536588A and CN211066679U. Cold air is sucked in through the air inlet of the detector, and the air outlet of the detector is roughly 90° to the air inlet. After the airflow passes through the electronic components in the detector, it bends 90° and is discharged from the air outlet. The discharged hot air still remains in the cavity where the detector is located.

[0047] In the related art, since the air inlet and outlet of the detector are roughly distributed at 90 degrees, the airflow needs to be bent, which increases the wind resistance and reduces the heat dissipation efficiency; and at the same time, the hot air discharged by the detector still remains in the cavity where the detector is located and can be easily sucked into the detector again. Due to the high temperature of the hot air, the heat dissipation efficiency of the wind flow on the detector module is reduced.

[0048] In response to the above technical problems, the present application provides a detector and medical imaging equipment, in which the air inlet and air outlet of the detector are roughly located on the same straight line, the airflow goes in and out directly, there is no airflow bending phenomenon, the airflow is subject to small wind resistance, and the heat dissipation efficiency of the electronic components in the detector is high, which solves the problem of low heat dissipation efficiency caused by the air inlet and air outlet of the detector being roughly 90° distributed. In addition, the air outlet of the detector can be directly connected to the cavity, and the hot air formed after heat exchange is directly discharged to the heat cavity, which solves the problem of hot air reflux into the detector in the related art.

[0049] Based on the above design ideas, the present application provides a detector and a medical imaging device, which aims to at least to some extent solve the technical problem that the temperature of electronic devices in the detector increases, affecting the stability of data acquisition and ultimately affecting the quality of the generated image.

[0050] Figure 1 shows a schematic diagram of the structure of a detector in one or more embodiments of the present application, Figure 2 Shows Figure 1 Schematic diagram of the collective structure of Figure 1 as well as Figure 2 The detector includes a shell 1, an electronic device 2 and a first air induction member 3. The shell 1 is provided with an air inlet 111 and an air outlet 112. At least a portion of the air inlet 111 and at least a portion of the air outlet 112 are arranged opposite to each other. The electronic device 2 is arranged in the shell 1. The first air induction member 3 is arranged in the shell 1 to introduce cold air into the shell 1 through the air inlet 111, and discharge hot air formed after heat exchange with the electronic device 2 through the air outlet 112.

[0051] The detector provided by the present application has an air inlet 111 and an air outlet 112 provided on the shell 1, an electronic device 2 is provided in the shell 1, and a first air induction member 3 is provided on the shell 1. When the first air induction member 3 is in operation, cold air is introduced into the shell 1 through the air inlet 111, and hot air is formed after heat exchange between the cold air and the electronic device 2, and the hot air is discharged through the air outlet 112. Since at least part of the air inlet 111 and at least part of the air outlet 112 are arranged relative to each other, the airflow flows out in a straight line or nearly straight line, the airflow has a small wind resistance, and the heat dissipation efficiency of the electronic device 2 is high, thereby improving the technical problem of the temperature increase of the electronic device 2 in the detector, avoiding affecting the stability of data acquisition, and improving the quality of the generated image, which has good practicality.

[0052] Combination Figure 1 as well as Figure 2The housing 1 is generally arched so that the detector can always be centered on the subject during the rotation process. The housing 1 includes a base 11 and an outer cover 12. The base 11 is the main bearing component of the detector and also serves as the internal and external interface of the detector. The top and bottom of the base 11 may be provided with openings, which may be sealed by the outer cover 12. The outer cover 12 is detachably mounted on the base 11, which facilitates the assembly and maintenance of the components inside the housing 1 on the one hand, and also serves as a protective function on the other hand.

[0053] Combination Figure 1 as well as Figure 2 The shell 1 has a relative air inlet side and an air outlet side, and the air inlet side and the air outlet side are arranged on opposite sides of the base 11. The air inlet side is provided with more than one air inlet 111, and the air outlet side of the shell 1 is provided with more than one air outlet 112. The air inlet 111 and the air outlet 112 are arranged correspondingly, and at least a part of the air inlet 111 and at least a part of the corresponding air outlet 112 are arranged relatively to each other, so that the corresponding air inlet 111 and the air outlet 112 are located in the same straight line or approximately in the same straight line, and the cold air introduced from the air inlet 111 is subjected to heat exchange to form hot air from the corresponding air outlet. Therefore, the flow of the airflow is discharged in a straight line or a nearly straight line, the wind resistance of the airflow is small, and the heat dissipation efficiency of the electronic device 2 is improved.

[0054] Combination Figure 1 In some embodiments, multiple groups of electronic devices 2 are provided, and each group of electronic devices 2 is arranged between the corresponding air inlet 111 and the air outlet 112. Most of the cold air introduced through the air inlet 111 is heat-exchanged with the electronic devices 2 located in the wind direction of the airflow to improve the heat dissipation efficiency of the electronic devices 2.

[0055] In other embodiments, the number of air inlets 111 and air outlets 112 may be inconsistent. For example, more air inlets 111 may be provided as auxiliary air inlets 111 to increase the intake volume of cold air; more air outlets 112 may be provided as auxiliary air outlets 112 to increase the output volume of hot air.

[0056] Combination Figure 1 In some embodiments, a first air induction member 3 is provided in the air inlet 111 to actively introduce cold air into the housing 1. In other embodiments, a first air induction member 3 may be provided in the air outlet 112 or in the housing 1, or a first air induction member 3 may be provided in at least two locations among the air inlet 111, the air outlet 112 and the housing 1. The first air induction member 3 may be a fan.

[0057] Combination Figure 1 as well as Figure 2In some embodiments, a first air induction member 3 may be provided in each air inlet 111 to provide cold air to the electronic device 2 between the air inlet 111 and the corresponding air outlet 112 to maximize the heat dissipation effect of the electronic device 2 .

[0058] Figure 3 Shows Figure 1 Schematic diagram of the structure of the electronic device in Figure 4 Shows Figure 1 Schematic diagram of the wind path in. Figure 3 as well as Figure 4 In some embodiments, the electronic device 2 may include a bracket 21, an electronic module 22 and an anti-scattering grid 23, wherein the bracket 21 is the main bearing component of the electronic device 2 and also bears the internal and external interface function of the electronic device 2. The electronic module 22 is arranged in the housing 1. The electronic module 22 is composed of a scintillator, a photodiode and an AD chip. The scintillator converts X-rays into visible light, the photodiode converts visible light into electrical signals, and the AD chip finally converts analog electrical signals into digital signals for output. Multiple electronic modules 22 are sequentially arranged on the top of the bracket 21 along the direction from the air inlet 111 to the corresponding air outlet 112. Multiple electronic modules 22 can be arranged on the top of the bracket 21 by connecting members such as pins and screws, and are the main heat source of the detector. The anti-scattering grid 23 is arranged on the top of the bracket 21 and covers the multiple electronic modules 22 to shield the scattered rays. The anti-scattering grid 23 can be arranged on the top of the bracket 21 by connecting members such as screws and pins.

[0059] Combination Figure 3 as well as Figure 4 In some embodiments, the bracket 21 may include a support plate 211 and a mounting plate 212. The mounting plate 212 is arranged on the top of the support plate 211. The mounting plate 212 and the support plate 211 can be integrally formed. Both ends of the mounting plate 212 can protrude from both ends of the support plate 211, so that the two ends of the mounting plate 212 can be assembled on the air inlet side and the air outlet side of the base 11 through bolts and other connecting parts. The electronic module 22 and the anti-scatter grid 23 are both installed in the middle of the mounting plate 212.

[0060] Combination Figure 3 as well as Figure 4 In some embodiments, the detector may further include a heat sink 4, which may be arranged on the bracket 21 by means of screws or other connectors. The heat sink 4 may exchange heat with the electronic device 2 to accelerate the conduction of heat in the housing 1, so as to further improve the heat dissipation efficiency of the electronic device 2. In a specific implementation, a heat sink 4 may be arranged on at least one side of the support plate 211. The heat generated by the electronic module 22 is transferred to the heat sink 4 through the bracket 21, so as to achieve heat exchange between the heat sink 4 and the electronic device 2.

[0061] Combination Figure 3 as well as Figure 4 In some embodiments, heat sinks 4 may be provided on both sides of the support plate 211. The heat sinks 4 may be made of metal materials with good heat dissipation properties and may be assembled on the support plate 211 by bonding or screw connection. In other embodiments, heat sinks 4 may also be provided on one side of the support plate 211.

[0062] Combination Figure 3 as well as Figure 4 In some embodiments, the area of ​​the heat sink 4 facing the air inlet 111 is smaller than the area of ​​the heat sink 4 facing the air outlet 112, that is, the area of ​​the heat sink 4 on the air inlet 111 side is smaller than the area of ​​the heat sink 4 on the air outlet 112 side. This is because, after the cold air is sucked into the detector, the path it takes to reach the corresponding air outlet 112 is longer, and the temperature of the air flow is low when passing through the electronic module 22 upstream of the air flow, and the temperature of the air flow is high when passing through the electronic module 22 downstream of the air flow, resulting in a large temperature gradient of the electronic module 22 in the air flow path, that is, the temperature of the electronic module 22 on the air inlet 111 side is relatively low, and the temperature of the electronic module 22 on the air outlet 112 side is relatively high. By designing that the area of ​​the heat sink 4 on the air inlet 111 side is smaller than the area of ​​the heat sink 4 on the air outlet 112 side, the electronic module 22 downstream of the air flow with a higher temperature can be more effectively dissipated, which has good practicality.

[0063] Combination Figure 3 as well as Figure 4 In some embodiments, the heat sink 4 can be designed with unequal lengths, that is, the number of heat sinks 4 on the air inlet 111 side is relatively small, and the number of heat sinks 4 on the air outlet 112 side is relatively large, so as to increase the convection heat exchange area with the bracket 21 and improve the heat dissipation efficiency.

[0064] Combination Figure 3 as well as Figure 4 In a specific implementation, the heat sink 4 can be vertically arranged in multiple rows, and the length of each row of heat sink 4 gradually decreases from top to bottom, so that the area of ​​the heat sink 4 on the air inlet 111 side is smaller than the area of ​​the heat sink 4 on the air outlet 112 side; in addition, since the heat sink 4 located at the top is longer, the heat generated by the electronic module 22 can be effectively dissipated.

[0065] Combination Figure 3 as well as Figure 4 In some embodiments, the ends of the multiple heat sinks 4 facing the air outlet 112 are located in the same vertical direction, preferably flush with the side of the support plate 211 facing the air outlet 112, and the ends of the multiple heat sinks 4 facing the air inlet are moved away from the air inlet 111 from top to bottom in sequence, so as to increase the size of the heat sink 4 as quickly as possible and improve the heat dissipation effect.

[0066] In other embodiments, the length of each row of heat sinks 4 may also gradually decrease from bottom to top, which is not limited here.

[0067] In the related art, since the bracket 21 and the part of the electronic module 22 in contact with the bracket 21 are all made of aluminum, the thermal conductivity is 220W / mk. Under this thermal conductivity, it is difficult to reduce the temperature gradient of the electronic device 2 by simple heat conduction. Figure 3 as well as Figure 4 Based on this, the detector of the present application also includes a heat spreader 5, which is arranged on the support plate 211 and / or the mounting plate 212 and the electronic module 22. The heat spreader 5 is used to improve the thermal conductivity of the bracket 21 to improve the thermal conductivity efficiency of the electronic device 2 and reduce the temperature gradient of the electronic device 2.

[0068] In some embodiments, the heat spreader 5 can be set on the support plate 211 and / or the mounting plate 212 by bonding or screw connection. Its material can be graphene or VC (Chinese name: vacuum chamber heat spreader technology; English name: VaporChamber), and its thermal conductivity can reach 4000W / mk. The heat spreader 5 fits tightly with the side of the bracket 21 and the side of the electronic module 22. The high thermal conductivity of the heat spreader is used to improve the thermal conductivity of the electronic device 2 and reduce the temperature gradient of the electronic device 2. According to actual tests, the temperature gradient of the electronic device 2 can be reduced by 50% by using this type of heat spreader.

[0069] In some embodiments, the detector may further include an air guide 6, a plurality of brackets 21 are disposed on the air guide 6, the air guide 6 may be disposed in the outer cover 12, and provided with an escape portion for avoiding components in the housing 1. The provision of the air guide 6 may reduce the volume inside the housing 1, increase the air flow velocity, and make the air flow more focused in the process of flowing through the electronic device 2, so as to improve the heat exchange effect on the electronic device 2.

[0070] The detector provided in the present application, through the design planning of the positions of the air inlet 111 and the air outlet 112, and the drainage function of the air guide 6, the airflow inside the detector basically maintains a straight in and out mode, without passing through resistance such as bending, and has high heat dissipation efficiency. It effectively solves the problem of low heat dissipation efficiency caused by the air inlet 111 and the air outlet 112 of the detector being roughly distributed at 90°, and has good practicality.

[0071] Based on the above detector, the present application also provides a medical imaging device. Figure 5 It shows a Figure 1 The schematic diagram of the structure of the medical imaging device of the detector shown in FIG. Figure 5The medical imaging device comprises a first cavity 7 and a second cavity 8 which are connected to each other. The first cavity 7 is provided with a first air outlet 71, and the second cavity 8 is provided with a second air outlet 81. The above-mentioned detector is arranged in the first cavity 7, and the first air outlet 71 and / or the second air outlet 81 are provided with a second air induction member 9.

[0072] The medical imaging device provided by the present application has an air inlet 111 and an air outlet 112 provided on the housing 1 of the detector, an electronic device 2 is provided in the housing 1, and a first air induction member 3 is provided on the housing 1. When the first air induction member 3 is in operation, cold air is introduced into the housing 1 through the air inlet 111, and hot air is formed after heat exchange between the cold air and the electronic device 2, and the hot air is discharged through the air outlet 112. Since at least part of the air inlet 111 and at least part of the air outlet 112 are arranged relative to each other, the airflow flows out in a straight line or nearly straight line, the airflow has a small wind resistance, and the heat dissipation efficiency of the electronic device 2 is high, thereby improving the technical problem of the temperature increase of the electronic device 2 in the detector, so as to avoid affecting the stability of data acquisition, improve the quality of the generated image, and have good practicality.

[0073] Combination Figure 5 In some embodiments, the first cavity 7 can be a cold cavity, and a second air induction member 9 can be provided in the first air outlet 71 of the first cavity 7, so as to introduce cold air into the first cavity 7 through the second air induction member 9, dissipate heat from the core components such as the bulb, high-voltage generator and detector in the first cavity 7, take away the heat of the core components, and convert it into hot air, which is then introduced into the second cavity 8. A second air induction member 9 is also provided at the second air outlet 81 of the second cavity 8, and the second air induction member 9 works to discharge the hot air in the second cavity 8 to the outside. During the whole process, the first cavity 7 is always in a positive pressure state, and the second cavity 8 is always in a negative pressure state, which can ensure that the hot air in the second cavity 8 will not flow back into the first cavity 7, and has good practicality.

[0074] Combination Figure 4 as well as Figure 5 In addition, the air outlet 112 of the detector shell 1 can be connected to the second cavity 8 through the air guide tube 10. The air guide tube 10 can be a straight tube to discharge the hot air in the shell 1 directly into the second cavity 8, and discharge the hot air under the action of the second air induction member 9 of the second cavity 8 to prevent the hot air from flowing back and being re-absorbed by the detector fan.

[0075] It should be noted that the cold air can also be introduced through the second air induction member 9 of the second cavity 8, and the hot air after heat exchange can be led out through the first air induction member 3 in the first cavity 7, that is, Figure 6 shown.

[0076] In other embodiments, the second air induction member 9 may be provided only in the first air outlet 71 of the first cavity 7, or the second air induction member 9 may be provided only in the second air outlet 81 of the second cavity 8, which can also achieve the technical purpose of introducing cold air and leading out hot air, which will not be elaborated here.

[0077] Combination Figure 5 as well as Figure 6 In some embodiments, the first cavity 7 and the second cavity 8 can be arranged in parallel, and an insulating member is provided between the first cavity 7 and the second cavity 8 to prevent the airflows in the two cavities from generating heat exchange and affecting the heat dissipation effect of the detector.

[0078] In summary, the detector and medical imaging equipment provided in the present application have a straight-in and straight-out wind path design, and the air outlet 112 of the detector is connected to the second cavity 8 of the medical imaging equipment through the air guide tube 10. The hot air is directly discharged into the second cavity 8. The first air induction member 3 on the detector will not reabsorb the heat flow, thereby improving the heat dissipation efficiency of the detector, thereby improving the technical problem of the temperature increase of the electronic device 2 in the detector, so as to avoid affecting the stability of data acquisition, improve the quality of the generated image, and have good practicality.
