Description

Technical Field

[0001] This application relates to the field of medical scanning processing technology, and more particularly to a heat dissipation structure and a medical device. Background Technology

[0002] In medical scanning technology, detection equipment often needs to dissipate heat, and the main way to dissipate heat is through air cooling. In medical equipment, such as computed tomography (CT) scanners, fans need to be installed to achieve air cooling. However, the addition of fans increases the height of the CT equipment, which is not conducive to the compact design of the CT equipment and the application of the CT equipment in environments with limited height space, such as mobile hospitals and vehicles. At the same time, the fans will generate a lot of noise, which will affect the perception of medical staff and result in a poor experience. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, a first aspect of the present invention provides a heat dissipation structure.

[0005] A second aspect of the present invention provides a medical device.

[0006] In view of this, a heat dissipation structure is provided according to a first aspect of the embodiments of this application, comprising:

[0007] The housing body surrounds the scanning cavity, and the interior of the housing body is provided with a receiving space for accommodating functional components;

[0008] The first vent is located at the top of the housing body and communicates with the receiving space;

[0009] The second vent is located at the bottom of the housing body and communicates with the receiving space;

[0010] A fan is disposed within the receiving space and communicates with the second vent, for allowing cooling air to flow in from one of the first vent and the second vent, and to flow out from the other of the first vent and the second vent.

[0011] In one feasible implementation, the fan includes an exhaust fan, the first vent is an air inlet, and the second vent is an air outlet; or,

[0012] The fan includes a blower, the first vent is an air outlet, and the second vent is an air inlet.

[0013] In one feasible implementation, the air vent connected to the second vent is a first air vent, the fan includes a second air vent connected to the first air vent, and the ratio of the shortest distance between the second air vent and the functional component in the accommodating space to the diameter of the fan is greater than or equal to 9%.

[0014] In one feasible implementation, in the extending direction of the scanning cavity, the width of the first vent is greater than or equal to 80% of the width of the functional component.

[0015] In one feasible implementation, the housing body includes a first housing plate and a second housing plate disposed opposite each other along the extension direction of the scanning cavity, and a side plate connecting the first housing plate and the second housing plate, wherein the second vent is disposed on at least one of the first housing plate, the second housing plate, or the side plate.

[0016] In one feasible implementation, the heat dissipation structure further includes:

[0017] An air guide component connects the fan and the second vent, serving to separate the fan from the second vent and reduce the noise of the fan.

[0018] In one feasible implementation, the air guide includes:

[0019] The housing connects the second vent and the fan;

[0020] A porous sound-absorbing layer is disposed on the inner wall of the enclosure.

[0021] In one feasible implementation, the heat dissipation structure further includes:

[0022] A soundproofing component is disposed within the accommodating space and is positioned opposite to the first vent.

[0023] A mesh panel is placed over or embedded within the first vent.

[0024] According to a second aspect of the embodiments of this application, a medical system is provided, comprising: functional components and a heat dissipation structure as described in any of the above technical solutions.

[0025] In one feasible implementation, the first vent is an air inlet, the fan is an exhaust fan, and the medical system further includes a cold air supply device disposed above the first vent.

[0026] Compared with the prior art, the present invention has at least the following beneficial effects: The heat dissipation structure provided in this application includes a housing body, a first vent at the top of the housing body, and a fan at the bottom of the housing body. During use, the accommodating space within the heat dissipation structure provided in this application is used to accommodate functional components, which can be used for patient testing. To dissipate heat from the functional components, the fan can be turned on, and the air generated by the fan will flow through the accommodating space. When the fan is a negative pressure fan, the air will enter the accommodating space through the first vent. When the fan is an airflow output device, the airflow can first flow through the accommodating space and then be discharged outside the housing through the first vent. When the airflow or wind flows through the functional components, it can dissipate heat from the functional components. In the heat dissipation structure provided in this application, the first vent is arranged at the top of the housing body, and the fan is arranged at the bottom of the housing body. This layout, on the one hand, can meet the heat dissipation requirements while making full use of the space at the bottom of the housing body, without increasing the height of the heat dissipation structure due to the addition of the fan. This is particularly beneficial for the compactness and miniaturization of medical devices, making it easier to apply medical devices in modular medical facilities and for transporting or mounting medical devices in vehicles.

[0040] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0041] Taking CT equipment as an example, this application considers that the heat dissipation performance of CT equipment is directly related to the stability of the detector and the quality of the image. Therefore, the heat dissipation effect has become an important factor in evaluating the quality of CT products. Most CT products on the market adopt air cooling, which depends on the placement of the fan and the design of the air duct. In traditional technology, air cooling of CT products mostly adopts an airflow design that conforms to natural convection, that is, the fan is placed on the top of the gantry. However, placing the fan on the top of the gantry has several drawbacks. First, it needs to avoid the rotation diameter of the rotating parts, which will undoubtedly increase the height of the scanning gantry. If it is placed on the upper rear side of the gantry, even if it avoids the rotating parts, it will still be restricted by the structure of related air duct seals, which will inevitably increase the height of the gantry. On the other hand, in order to improve heat dissipation efficiency, sealing and guiding structures are added to the gantry to achieve a hot and cold zone air duct design. Furthermore, since the fan is placed on the top of the gantry, the gap between the exhaust fan and the rotating parts or related air duct seals is generally very small, resulting in a large air resistance of the exhaust fan, which leads to a decrease in airflow and a reduction in heat dissipation efficiency. Moreover, the increased air resistance will increase the noise level of the fan itself.

[0042] Furthermore, the inventors discovered that the overall noise of the CT scanner is composed of the combined noise from the gantry rotor and the cooling fan. Because multiple exhaust fans are located at the top of the gantry, their noise is directly radiated to the outside of the equipment through the exhaust vents. In particular, the high-speed fans used to increase ventilation can generate noise exceeding that of the gantry rotor, significantly increasing the overall noise level of the device. Moreover, the top fans are positioned close to ear height, directly impacting the operator and worsening the working environment for medical staff.

[0043] like Figures 1 to 2 As shown, where the arrows indicate the airflow direction, a heat dissipation structure is proposed according to a first aspect of the present application, comprising: a housing body 110 forming a scanning cavity, and the housing body 110 having an internal accommodating space for accommodating a functional component 210; a first vent 120 located at the top of the housing body 110 and communicating with the accommodating space; a second vent 140 located at the bottom of the housing body 110 and communicating with the accommodating space; and a fan 130 disposed within the accommodating space and communicating with the second vent 140, for allowing cooling air to flow in from one of the first vent 120 and the second vent 140 and flow out from the other of the first vent 120 and the second vent 140.

[0044] The heat dissipation structure provided in this embodiment includes a housing body 110, a first vent 120 opened at the top of the housing body 110, and a fan 130 disposed at the bottom of the housing body 110. During use, the accommodating space within the heat dissipation structure is used to accommodate the functional component 210 of the detection device. This functional component 210 can be used to detect patients. To dissipate heat from the functional component 210, the fan 130 can be turned on. The air generated by the fan 130 flows through the accommodating space. When the fan 130 is a negative pressure fan, such as... Figure 1 As shown, air enters the containment space through the first vent 120. When the fan 130 is the device for outputting airflow, such as... Figure 2As shown, the airflow can first flow through the accommodating space and then be discharged outside the housing through the first vent 120. When the airflow or wind flows through the functional component 210 of the detection device, it can dissipate heat for the functional component 210 of the detection device. In the heat dissipation structure provided in this embodiment, the first vent 120 is arranged at the top of the housing body 110, and the fan 130 is arranged at the bottom of the housing body 110. This layout can, on the one hand, meet the heat dissipation requirements while making full use of the space at the bottom of the housing body 110, without increasing the height of the heat dissipation structure due to the addition of the fan 130. This is particularly beneficial for the compactness and miniaturization of medical devices, making it easier to apply medical devices in modular cabins and for transporting or vehicle-mounting medical devices. On the other hand, the fan 130, as the main source of noise, is located at the bottom of the housing body 110, away from medical personnel, which can reduce the noise perceived by medical personnel, improve their experience, and especially improve their working environment.

[0045] Taking the heat dissipation structure provided in this application embodiment as an example applied to a CT device, the heat dissipation structure provided in this application embodiment has a first vent 120 formed on the top of the housing body 110, and a fan 130 disposed at the bottom of the housing body 110. With this arrangement, firstly, the fan 130 can make full use of the space at the bottom of the housing body 110. The fan 130 can be disposed inside the housing body 110 or connected to the outer wall of the housing body 110, without increasing the height of the CT device, thus eliminating the impact of the top-mounted fan on the overall size of the device and improving the product's application capability in confined spaces; secondly, it can reduce the number of air guiding devices, which is conducive to the compactness and miniaturization of the CT device; thirdly, it helps to keep the fan 130 away from the rotating parts of the CT device, which helps to reduce the air resistance of the fan 130, reduce the noise of the fan 130, and improve the heat dissipation efficiency; fourthly, it can keep the noise source away from the hearing height of medical staff, reduce the impact of noise on operators and patients, and optimize the working environment of medical staff.

[0046] It is understandable that when the functional component is a functional component of a CT device, the functional component is a rotor.

[0047] In this technical solution, the heat dissipation structure also has a second vent 140. This arrangement can form a passage from the first vent 120 to the accommodating space to the second vent 140, which facilitates airflow convection and can improve the heat dissipation effect.

[0048] like Figure 1 and Figure 2 As shown, in some examples, the second vent 140 is located on both sides of the bottom of the housing body 110, or on the front and rear sides of the bottom of the housing body 110; the fan 130 can be arranged in different ways to adapt to different spatial structures.

[0049] It is understandable that, in order to further simplify the heat dissipation structure and reduce the cost of medical devices, the heat dissipation structure provided in this application embodiment does not require a fan 130 on top.

[0050] In one feasible implementation, the fan 130 includes an exhaust fan, a first vent 120 as an air inlet, and a second vent 140 as an air outlet.

[0051] In this technical solution, such as Figure 1 As shown, the fan 130 may include an exhaust fan, meaning that when the fan 130 is turned on, the fan 130 can draw in air through the first vent 120 at the top of the housing body 110, so that the airflow enters the housing body 110 through the first vent 120, and then flows through the receiving space and the functional components 210 disposed within the receiving space, such as... Figure 3 As shown, where Figure 3 The direction of the middle arrow indicates the airflow direction. When the fan 130 at the bottom of the housing body 110 is working, a negative pressure is formed inside the housing body 110, which forces the external cold airflow to be drawn in from the top first vent 120. This can cool the CT rotating component set in the housing space. The heat dissipation capacity can be adjusted by allocating the number of fans 130 at the bottom of the housing body 110, or by setting a high-flow exhaust fan for speed adjustment, to meet the different heat dissipation needs of the series of products.

[0052] It is understandable that when fan 130 is an exhaust fan, and medical devices are used in indoor environments, the room is usually equipped with cooling equipment, such as central air conditioning or ducted air conditioning units. These cooling devices, combined with the exhaust fan and using a top-intake design, allow the cooled air to be directly drawn into the first vent 120 without being mixed with warm indoor airflow, thus cooling the internal heat dissipation components and effectively improving the overall heat dissipation performance. This makes medical devices using the heat dissipation structure provided in this application particularly suitable for hospital radiology rooms, mobile hospitals, and vehicle-mounted devices with central air conditioning vents in the ceiling, improving the overall heat dissipation performance.

[0053] It is understandable that when the fan 130 is an exhaust fan, the heat dissipation path is top intake and bottom exhaust. Since dust generally comes from the ground, the top exhaust method requires the addition of a filter, which increases the intake resistance, making the fan more powerful and thus noisier. The bottom exhaust method does not require a filter, reduces the fan power, and correspondingly reduces the noise.

[0054] In one feasible implementation, such as Figure 2 As shown, the fan 130 includes a blower, a first vent 120 which is an air outlet, and a second vent 140 which is an air inlet.

[0055] In this technical solution, the fan 130 may also include a blower, that is, the fan 130 can blow air, and the airflow generated by the blower first passes through the receiving space and then is discharged through the first vent 120. With this configuration, the fan 130 can be externally mounted on the outer wall of the housing body 110, which facilitates the installation, disassembly and maintenance of the fan 130.

[0056] It is understandable that the air supply fan can be a blower fan, forming an airflow path with air intake at the bottom and exhaust at the top. This solution can also meet the heat dissipation requirements and will also reduce the impact of the cooling fan on the overall noise of the machine.

[0057] like Figure 3 As shown, in one feasible implementation, there are two or more first vents 120, and the two or more first vents 120 are arranged at intervals.

[0058] In this technical solution, there can be two or more first vents 120. This arrangement can improve the air intake or exhaust efficiency of the housing body 110, while reducing the wind resistance of the fan 130 and further suppressing noise.

[0059] like Figure 1 and Figure 2 As shown, in one possible implementation, there are two or more fans 130, which are arranged on different walls of the housing body 110.

[0060] In this technical solution, there can be two or more fans 130. This arrangement allows the housing body 110 to have multiple airflow channels, which enables airflow to flow better through the functional components 210 located in the accommodating space, thereby improving the heat dissipation effect on the functional components 210.

[0061] In one feasible implementation, such as Figure 4 and Figure 5 As shown, the air vent connected to the second air vent 140 of the fan 130 is the first air vent. The fan 130 includes a second air vent connected to the first air vent. The ratio of the shortest distance between the second air vent and the functional component 210 in the accommodating space to the diameter of the fan 130 is greater than or equal to 9%.

[0062] In this technical solution, the positional relationship between the fan 130 and the functional component 210 is further provided. During use, the functional component 210 acts as an obstacle to the fan 130, which will affect the air pressure and wind speed. The ratio of the shortest distance between the fan 130 and the functional component 210 to the diameter of the fan 130 is greater than or equal to 9%, which can ensure that the fan 130 has sufficient pressure and wind speed to guarantee the heat dissipation effect.

[0063] like Figure 4As shown, x is the distance between fan 130 and functional component 210, and D is the diameter of fan 130. Figure 5 As shown, the air supply status is illustrated under different ratios of x to D over time. Figure 5 The vertical axis represents the increase in static pressure, and the horizontal axis represents the wind speed. In curve 1, the ratio of x to D is infinitely large, indicating that there are no obstacles or no functional components 210 are installed. In curve 2, the ratio of x to D is 35%. In curve 3, the ratio of x to D is 18%. In curve 4, the ratio of x to D is 9%. In curve 5, the ratio of x to D is 5%. Figure 6 It can be seen that when the ratio of the shortest distance between the fan 130 and the functional component 210 to the diameter of the fan 130 is greater than or equal to 9%, the fan 130 can ensure that it has sufficient pressure and wind speed. However, when the ratio of the shortest distance between the fan 130 and the functional component 210 to the diameter of the fan 130 is less than 9%, the pressure and wind speed of the airflow generated by the fan 130 will decrease.

[0064] As a preferred option, the ratio of the shortest distance between the fan 130 and the functional component 210 to the diameter of the fan 130 can be greater than or equal to 17%. For example, if the fan 130 is an axial flow fan with an impeller diameter of 220mm, the gap between the fan 130 and the functional component 210 needs to be at least 39.6mm to minimize the impact of the functional component 210 on the fan's airflow and air pressure.

[0065] In one feasible implementation, in the extension direction of the scanning cavity ( Figure 3 In the Y direction, the width of the first vent 120 is greater than or equal to 80% of the width of the functional component 210.

[0066] In this technical solution, the dimensions of the first vent 120 are further provided. The width of the first vent 120 is greater than or equal to 80% of the width of the functional component, which can improve the heat dissipation efficiency of the functional component.

[0067] In one feasible embodiment, the housing body 110 includes a first housing plate and a second housing plate disposed opposite each other along the extension direction of the scanning cavity, and a side plate connecting the first housing plate and the second housing plate, and a second vent 140 is disposed on at least one of the first housing plate, the second housing plate, or the side plate.

[0068] In this technical solution, the structural composition of the shell body is further provided. The shell body includes a first shell plate, a second shell plate and a side plate. This arrangement makes the shell body a split design, which facilitates the assembly of the shell body and the processing of the first through hole 130 and the second vent 140.

[0069] In one feasible implementation, such as Figure 6 and Figure 7 As shown, the heat dissipation structure also includes: an air guide 150, which connects the fan 130 and the second vent 140, and is used to separate the fan 130 from the second vent 140 and reduce the noise of the fan 130.

[0070] In this technical solution, the heat dissipation structure may also include an air guide 150. The air guide 150 provides an installation position for the fan 130, facilitating its installation and fixation. In addition, when the fan 130 is an exhaust fan, the exhaust end of the exhaust fan can be connected to the air guide 150, which facilitates guiding the hot airflow of the fan 130 to the second vent 140. Furthermore, the air guide 150 has a certain width, which can separate the fan 130 from the outer wall of the housing body 110, which is beneficial for attenuating the noise of the fan 130 instead of directly radiating it outside the heat dissipation structure.

[0071] In one feasible implementation, such as Figure 6 As shown, the air guide 150 includes: a housing 151 connected to the second vent 140 and the fan 130; and a porous sound-absorbing layer 152 disposed on the inner wall of the housing 151.

[0072] In this technical solution, a structure for the air guide 150 is further provided. The air guide 150 includes a housing 151 and a porous sound-absorbing layer 152 disposed within the housing 151. This housing 151 provides an installation position for the fan 130, facilitating its installation and fixation. Furthermore, when the fan 130 is an exhaust fan, its exhaust end can be connected to the air guide 150, guiding the hot airflow from the fan 130 to the second vent 140. Additionally, the air guide 150 has a certain width, separating the fan 130 from the outer wall of the housing 110, which helps attenuate fan noise instead of directly radiating it outside the heat dissipation structure. The porous sound-absorbing layer 152 guides the hot airflow and also attenuates noise. The porous sound-absorbing layer 152 further suppresses noise, and the sound-absorbing cotton also absorbs dust, ensuring the cleanliness of the heat dissipation structure.

[0073] In some examples, the porous sound-absorbing layer 152 may be made of porous materials such as polyurethane foam to reduce the propagation of exhaust fan noise and internal noise radially outward through the fan opening.

[0074] In one feasible implementation, the heat dissipation structure further includes a sound insulation element 160, disposed within the accommodating space and disposed opposite to the first vent 120.

[0075] In this technical solution, the heat dissipation structure may also include a sound insulation component 160. The sound insulation component 160 can suppress the noise of the air intake or exhaust at the first vent 120, thereby improving the noise reduction effect.

[0076] A schematic diagram illustrating the specific implementation structure of the noise reduction measures that can be selected in this technical solution. (See diagram for example.) Figure 6 As shown, in the part of the housing body 110, sound insulation components 160 are provided inside the two first vents 120. The sound insulation components 160 can be made of high-density sheet metal or other materials, which can reduce the amount of internal noise radiated outward through the first vents 120. At the same time, a considerable air intake area can still be maintained between the sound insulation components and the first vents 120, which reduces the impact on internal heat dissipation while providing sound insulation. Actual tests have proven that it does not reduce the overall heat dissipation capacity of the machine. In the lower part of the housing body 110, a porous sound-absorbing layer 152 can be provided inside the fan 130 and the air guide 150. The porous sound-absorbing layer 152 can be made of porous materials such as polyurethane foam, which reduces the propagation of fan 130 noise and internal noise radially outward through the fan vent.

[0077] In one feasible implementation, the heat dissipation structure further includes a mesh plate covering or embedded in the first vent 120.

[0078] In this technical solution, the heat dissipation structure may also include a mesh plate. By covering the first vent 120 with the mesh plate, external debris can be prevented from contacting or falling into the containment space, and intruders can be prevented from contacting the functional components 210, thereby improving the safety of the heat dissipation structure.

[0079] In one possible implementation, the ratio of the width of the housing 151 to the diameter of the fan 130 is greater than or equal to 9%.

[0080] In this technical solution, the dimensional relationship between the housing 151 and the fan 130 is further provided. It can be understood that the width of the housing 151 is the distance between the fan 130 and the housing body 110. The ratio of the width of the housing 151 to the diameter of the fan 130 is greater than or equal to 9%, which can greatly reduce noise.

[0081] In one possible implementation, the first vent 120 consists of a plurality of through holes formed on the housing body 110.

[0082] like Figure 8 As shown, a second aspect of the embodiments of this application provides a medical device, comprising: a heat dissipation structure as described in any of the above technical solutions; and a functional component 210 disposed within the accommodating space of the heat dissipation structure.

[0083] The medical device provided in this application embodiment has a heat dissipation structure in which a first vent 120 is formed on the top of the housing body 110, and a fan 130 is disposed at the bottom of the housing body 110. This arrangement has several advantages: First, the fan 130 can fully utilize the space at the bottom of the housing body 110. The fan 130 can be disposed within the housing body 110 or connected to the outer wall of the housing body 110, without increasing the height of the medical device, thus eliminating the impact of a top-mounted fan on the overall size and improving the product's application capability in confined spaces. Second, it reduces the need for air guiding devices, facilitating the compactness and miniaturization of the medical device. Third, it keeps the fan 130 away from the rotating parts of the medical device, reducing the fan's air resistance and noise, while improving heat dissipation efficiency. Fourth, it keeps the noise source away from the hearing height of medical personnel, reducing the impact of noise on operators and patients, and optimizing the working environment for medical personnel.

[0084] In one feasible implementation, the functional component 210 includes: a computed tomography (CT) scanner; a first vent 120 arranged radially along the CT scanner, and the length of the first vent 120 being greater than or equal to the diameter of the CT scanner; and / or the first vent 120 arranged axially along the CT scanner, and the length of the first vent 120 being greater than or equal to the length of the CT scanner; and / or the ratio of the shortest distance between the fan 130 and the functional component 210 to the diameter of the fan 130 being greater than or equal to 9%.

[0085] In this technical solution, the functional component 210 may include a computed tomography (CT) device, enabling the medical device to be used as a CT equipment.

[0086] In this technical solution, when the functional component 210 includes a computed tomography (CT) scanner, the arrangement direction and size of the first vent 120 are further provided. The first vent 120 is arranged along the radial direction of the CT scanner, and the length of the first vent 120 is greater than or equal to the diameter of the CT scanner. This arrangement allows the first vent 120 to cover the CT scanner in the radial direction, thereby improving the heat dissipation efficiency of the CT scanner.

[0087] In this technical solution, the first vent 120 can also be arranged along the axial direction of the computed tomography (CT) device, and the length of the first vent 120 is greater than or equal to the length of the CT device, so that the first vent 120 can cover the CT device in the axial direction of the CT device, thereby improving the heat dissipation efficiency of the CT device.

[0088] In one feasible implementation, the first vent 120 is an air inlet, the fan 130 is an exhaust fan, and the medical system also includes a cold air supply device 220, which is disposed above the first vent 120.

[0089] like Figure 8 As shown, the cold air supply device 220 can be a central air conditioner installed on the ceiling. For products such as hospital radiology rooms, mobile hospitals, and vehicle-mounted units with central air conditioning vents on the ceiling, the cooled air can be directly drawn into the first vent 120 of the medical equipment without being mixed with the indoor hot airflow, thereby cooling the internal heat dissipation components and effectively improving the overall heat dissipation effect of the unit.

[0090] It is understandable that the cold air supply device 220 is located above the heat dissipation structure, meaning that the air outlet of the cold air supply device 220 faces the first vent 120 of the heat dissipation structure.

[0091] In this invention, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; the term "multiple" refers to two or more unless otherwise explicitly defined. The terms "install," "connect," "link," and "fix" should be interpreted broadly.
