Technical Field

[0001] This application relates to the field of imaging equipment technology, and in particular to a heat dissipation component and a camera. Background Technology

[0002] Scientific cameras, also known as scientific-grade cameras, are high-precision imaging devices specifically designed and manufactured for scientific research. They are widely used in fields such as astronomy, biology, materials science, and medical imaging. Compared to ordinary commercial cameras, scientific cameras typically have higher sensitivity, resolution, dynamic range, and more precise time control to meet the stringent requirements for image quality and data accuracy in scientific research.

[0003] Scientific cameras often generate significant heat due to long exposures or high frame rates. An effective cooling mechanism is essential to ensure image quality and equipment stability. Using fans to dissipate heat can improve the image performance and stability of scientific cameras. However, fan operation also generates vibrations, which, when transmitted to the camera body, can cause vibrations in the output image, affecting image quality.

[0004] However, the commonly used vibration reduction methods currently have problems such as poor vibration reduction effect, affecting heat dissipation, or difficulty in disassembly and assembly. Utility Model Content

[0005] The purpose of this application is to provide a heat dissipation component and a camera that achieves axial and radial vibration reduction of the fan through a simple structure, thereby improving the vibration reduction effect. Moreover, it does not require slowing down the fan speed, ensuring the heat dissipation effect and thus improving the imaging effect. At the same time, no additional fan bracket is required, and the fan can be removed from the camera body simply by removing the fasteners, making disassembly more convenient, simple, and cost-effective.

[0006] The embodiments of this application can be implemented as follows:

[0007] In a first aspect, this utility model provides a heat dissipation component, comprising:

[0008] The fan has connection holes.

[0009] A vibration damping pad includes an embedded section and an exposed section connected together. The embedded section is embedded in the connecting hole, and the exposed section is located outside the connecting hole. The vibration damping pad is provided with a through hole that penetrates the embedded section and the exposed section.

[0011] In an optional real-time mode, the fastener is interference-fitted with the vibration damping pad.

[0012] In an optional real-time mode, the embedded section of the vibration damping pad is interference-fitted with the fan.

[0013] In an optional embodiment, the outer diameter of the embedded section of the vibration damping pad is smaller than the outer diameter of the exposed section, which is mounted on the fan.

[0014] In an optional implementation, the embedded segment and the exposed segment are coaxial.

[0015] In an optional embodiment, the fastener is a screw, which includes a connected head and a shank, the shank passing through the through hole and used to connect the fan to other structural components, and the head being located on the exposed section away from the fan.

[0016] In an optional embodiment, the fastener is a shoulder screw, the shank includes a smooth section and a threaded section, the smooth section passes through the through hole, and the threaded section is used to connect other structural components.

[0017] In an optional embodiment, when the damping pad is not compressed, the outer diameter of the portion of the fastener used to pass through the through hole is larger than the inner diameter of the through hole.

[0018] In an optional embodiment, when the damping pad is not compressed, the outer diameter of the portion of the damping pad used to embed in the connecting hole is larger than the inner diameter of the connecting hole.

[0022] Compared with the prior art, the beneficial effects of the embodiments of this application include, for example:

[0023] By embedding the embedded section into the connecting hole and providing through holes through both the embedded and exposed sections, the fasteners can be connected to other structural components through these through holes to achieve fan installation. The exposed section outside the connecting hole provides axial vibration reduction between the structural components and the fasteners and the fan, respectively, while the embedded section provides radial vibration reduction between the fasteners and the fan.

Furthermore, no additional fan bracket is required, and the fan can be removed from the structural components simply by removing the fasteners, making disassembly more convenient, simple, and cost-effective.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application.

[0036] The existing fan vibration reduction methods mainly include the following:

[0037] 1. Vibration reduction is achieved through vibration damping pads;

[0038] 2. Vibration reduction is achieved using vibration damping nails;

[0039] 3. Reduce the fan speed;

[0040] 4. Vibration damping is achieved through springs.

[0041] However, the inventors discovered some problems with the above four methods:

[0042] In vibration reduction method 1, the fan vibration damping pad is generally ring-shaped, which can only reduce vibration in the axial direction, resulting in poor vibration reduction effect and thus affecting the imaging effect.

[0043] In vibration reduction method 2, the fan and fan bracket must first be connected by vibration damping nails, and then the fan bracket must be fixed to the surrounding structural components. The assembly is more troublesome, and the vibration damping nails must be destroyed after they are installed in order to disassemble the fan.

[0044] While reducing the fan speed in vibration reduction method 3 can effectively reduce vibration, it will also affect heat dissipation, which in turn will affect the imaging effect.

[0045] In vibration reduction method 4, the fan and fan bracket must first be fixed together with screws, and then the fan bracket is connected to the surrounding structural components with springs, making the assembly more complicated.

[0046] To address this, the inventors have developed a vibration reduction method that can simultaneously reduce fan vibration in both the axial and radial directions, while also ensuring effective heat dissipation and assembly.

[0047] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0048] This application discloses a camera, which includes a body and a heat dissipation assembly mounted on the body. The heat dissipation assembly is mainly used to dissipate heat from the body, thereby ensuring the output image quality and stability of the entire camera. The camera can be a scientific research camera or a commercial ordinary camera that requires heat dissipation.

[0049] Of course, it is understandable that the heat dissipation component can also be installed on other components that need heat dissipation, and is not limited to just dissipating heat from the camera body. In other words, the heat dissipation component can be installed on other structural components.

[0050] refer to Figure 1 and Figure 2 The heat dissipation assembly includes a fan 100, a vibration damping pad 200, and fasteners 300. The fan 100 is provided with a connection hole 110, which is mainly used to install the vibration damping pad 200 and then install the fan 100 onto the chassis or other structural components using fasteners.

[0051] The vibration damping pad 200 is embedded in the connection hole 110, and a portion of the vibration damping pad 200 is located outside the connection hole 110. The vibration damping pad 200 is provided with a through hole 210.

[0052] Fastener 300 is inserted through through hole 210 and used to connect structural components such as camera body to enable connection of fan 100 with other structural components.

[0053] As described above, by embedding a portion of the vibration damping pad 200 into the connecting hole 110, and simultaneously providing a through hole 210 for the fastener 300 to pass through, the fastener 300 can be connected to the body and other structural components to achieve the installation of the fan 100. Since a portion of the vibration damping pad 200 is exposed outside the connecting hole 110, this exposed portion can achieve axial vibration damping of the structural components and the fastener 300 with the fan 100, respectively. Furthermore, since the portion of the vibration damping pad 200 located inside the connecting hole 110 also contacts the fastener 300, radial vibration damping of the fan 100 can also be achieved. In this way, axial and radial vibration damping of the fan 100 is achieved through a simple structure, improving the vibration damping effect. Moreover, it is not necessary to slow down the fan 100 speed, ensuring heat dissipation and thus improving the imaging effect. At the same time, no additional fan bracket is required, and when removing the fan 100, only the fastener 300 needs to be removed to remove the fan 100 from the structural components, making disassembly more convenient, simple, and cost-effective.

[0054] Optional, see reference Figure 3 The vibration damping pad 200 can be a stepped structure. Specifically, the vibration damping pad 200 includes an embedded section 220 and an exposed section 230 connected together. A through hole 210 passes through the embedded section 220 and the exposed section 230. The outer diameter of the embedded section 220 is smaller than the outer diameter of the exposed section 230. The embedded section 220 is embedded in the connecting hole 110, while the exposed section 230 is located outside the connecting hole 110 and overlaps with the fan 100.

[0055] In this way, the embedded section 220 is squeezed by the inner wall of the connecting hole 110 and the fastener 300, mainly playing the role of radial vibration reduction of the fan 100; the stepped vibration damping pad 200 also has a positioning function, that is, the step difference between the exposed section 230 and the embedded section 220 can make the end face of the exposed section 230 abut against the surface of the fan 100, so as to ensure that the two sides of the fan 100 through which the connecting hole 110 passes are pressed together with the structural component and the fastener 300 to the exposed section 230, and the exposed section 230 plays the role of axial vibration reduction.

[0056] In other words, by embedding the embedded section 220 into the connecting hole 110, and simultaneously providing a through hole 210 that passes through the embedded section 220 and the exposed section 230, the fastener 300 can be connected to other structural components through the through hole to achieve the installation of the fan 100. The exposed section 230 located outside the connecting hole 110 can achieve axial vibration reduction between other structural components and the fastener 300 and the fan 100, respectively, while the embedded section 220 can achieve radial vibration reduction between the fastener 300 and the fan 100, thereby improving the vibration reduction effect.

[0057] The embedded section 220 and the exposed section 230 are coaxial to ensure a more uniform distribution of axial compressive force on the exposed section 230. The vibration damping pad 200 is made of materials with flexible, elastic, and vibration-damping properties, such as rubber or silicone. For example, the vibration damping pad 200 is a rubber vibration damping pad or a silicone vibration damping pad, which can absorb vibration energy and achieve good axial and radial vibration damping effects.

[0058] When the damping pad 200 is not compressed, the outer diameter of the portion of the damping pad 200 used to embed into the connecting hole 110 is larger than the inner diameter of the connecting hole 110. That is, when the embedded section 220 is not compressed, its outer diameter is larger than the inner diameter of the connecting hole 110. After the embedded section 220 is embedded into the connecting hole 110, the embedded section 220 and the fan 100 maintain an interference fit, which can ensure that the embedded section 220 can be fully radially compressed by the inner wall of the connecting hole 110 and the fastener 300, thereby ensuring the radial vibration damping effect.

[0059] Combination Figure 1 and Figure 3 The axial length of the vibration damping pad 200 is less than the axial length of the connecting hole 110. A vibration damping pad 200 is embedded at each end of the connecting hole 110. This makes it convenient to insert two vibration damping pads 200 into the connecting hole 110 from both sides. That is, there is an embedding section 220 of a vibration damping pad 200 at each end of the connecting hole 110. When the fan 100 is installed, the fastener 300 passes through the through hole 210 of one vibration damping pad 200, the connecting hole 110 and the through hole 210 of another vibration damping pad 200 in sequence and then connects with the structural component, which makes it convenient for the vibration damping pad 200 to be embedded in the connecting hole 110.

[0060] It is understandable that there is no specific limit to the number of connection holes 110; for example, it can be... Figure 1 and Figure 2 The four connecting holes 110 shown correspond one-to-one with the fasteners 300 and the connecting holes 110. There are eight vibration damping pads 200, with one vibration damping pad 200 installed at each end of each connecting hole 110.

[0061] It should also be noted that in some embodiments, the axial length of the damping pad 200 can also be greater than the length of the connecting hole 110. The two ends of the damping pad 200 extend from the two ends of the connecting hole 110, so that only one damping pad 200 needs to be installed in the connecting hole 110, which can also achieve axial and radial vibration reduction of the fan 100.

[0062] Optional, see reference Figure 2 and Figure 4The fastener 300 is a screw, which includes a connected head 310 and a shank 320. The shank 320 passes through the through hole 210 and is used to connect structural components to enable the fan 100 to connect with other structural components. The head 310 is located on the side of the exposed section 230 away from the fan 100, pressing against the portion of the vibration damping pad 200 exposed outside the connecting hole 110. In this way, the outer peripheral wall of the shank 320 and the inner peripheral wall of the connecting hole 110 jointly compress the embedded section 220 of the vibration damping pad 200 located in the connecting hole 110, and the head 310 presses against the exposed section 230, thereby achieving the locking installation of the fan 100 on the structural components and the axial and radial vibration damping of the fan 100. Disassembly and assembly are simple; just loosen the screw and then remove the fan 100.

[0063] The fastener 300 can be a shoulder screw, and the shank 320 includes a smooth shank section 330 and a threaded section 340. The smooth shank section 330 passes through the through hole 210, and the threaded section 340 is used to connect other structural components. In this way, the smooth shank section 330 passes through the through hole 210 on the adjusting pad to achieve radial vibration reduction. Since the shoulder screw only has partial threads, it cannot be tightened all the way down when the screw is tightened. Therefore, the axial compression of the vibration damping pad 200 can be controlled by controlling the length of the smooth shank section 320 of the shoulder screw.

[0064] When the damping pad 200 is not compressed, the outer diameter of the part of the fastener 300 that is inserted into the through hole 210 is larger than the inner diameter of the through hole 210. That is, the outer diameter of the smooth rod section 330 is larger than the inner diameter of the through hole 210. In this way, the fastener 300 and the damping pad 200 are interference-fitted, which can ensure that the embedded section 220 can be fully radially compressed by the inner wall of the connecting hole 110 and the fastener 300, thereby ensuring the radial damping effect.

[0065] The radial compression of the vibration damping pad 200 is controlled by designing a reasonable inner and outer diameter value of a small cylinder based on the size of the fan 100 mounting hole and the diameter of the shaft shoulder screw rod.

[0066] In summary, this application discloses a heat dissipation component and a camera. By embedding the embedded section 220 into the connecting hole 110 and providing a through hole 210 that passes through the embedded section 220 and the exposed section 230, the fastener 300 can pass through the through hole to connect with other structural components, thereby enabling the installation of the fan 100. The exposed section 230, located outside the connecting hole 110, can achieve axial vibration reduction between other structural components and the fastener 300 and the fan 100, respectively. The embedded section 220 can achieve radial vibration reduction between the fastener 300 and the fan 100, thereby improving the vibration reduction effect. Moreover, it is not necessary to slow down the fan 100 speed, ensuring the heat dissipation effect and thus improving the imaging effect. At the same time, no additional fan bracket is required. When removing the fan 100, only the fastener 300 needs to be removed to remove the fan 100 from the structural component, making disassembly more convenient, simple, and cost-effective.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
