Description

Technical Field

[0001] This application relates to the technical field of standard lamps for on-orbit radiation calibration, and particularly to a thermally conductive and vibration-damping structure and standard lamp device for on-orbit calibration standard lamps. Background Technology

[0002] Standard lamps are widely used as calibration light sources in on-orbit radiometric calibration. These lamps typically generate significant heat, and given the vacuum environment in orbit, it's crucial to dissipate this heat promptly. Furthermore, the bare lamp's exterior is encased in glass, and the windows and pins need to be sealed to maintain the vacuum. They must withstand the harsh mechanical environment during rocket launch. To address these issues, the current primary design solution involves using a clamping device to hold the standard lamp and then connecting this device to the equipment.

[0003] However, in practical applications, the inventors found that the main drawback of the relevant technical design is that the standard lamp cannot dissipate heat in time during long-term operation, resulting in excessively high temperatures. In addition, the standard lamps in the relevant technologies usually lack vibration isolation components. These problems not only affect the service life and performance of the standard lamps, but may even affect the success or failure of the calibration system.

[0059] Although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application.

[0060] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0061] As described in the background section, standard lamps are widely used as calibration light sources in on-orbit radiometric calibration. Standard lamps generally have high heat output, and given their location in the vacuum environment of on-orbit, it is crucial to dissipate the heat promptly. Furthermore, the bare lamp body is encased in glass, and the windows and pins need to be sealed to maintain the vacuum state; therefore, it must withstand the harsh mechanical environment during rocket launch. To address these issues, the current main design solution involves using a clamping device to hold the standard lamp and then connecting the clamping device to the equipment.

[0062] However, in practical applications, the inventors found that the main drawback of the related technology is that the standard lamp cannot conduct heat away when it works for a long time, resulting in excessively high temperature. The above problems not only affect the service life and working performance of the standard lamp, but may even affect the success or failure of the calibration system. In order to solve the above-mentioned technical problems, the inventive concept of this application was developed, which will be explained in detail through the following embodiments.

[0063] Example 1

[0064] The first aspect of this application provides a thermally conductive and vibration-damping structure for an on-orbit calibration standard lamp. This structure can at least be used for the installation, heat conduction, and vibration isolation of the standard lamp 6. Specific details will be provided through the following embodiments. Figure 1-Figure 1 As shown in Figure 2, the thermally conductive and vibration-damping structure may include a split thermally conductive cylinder 5 and a thermally conductive base 11, wherein:

[0065] The split heat-conducting cylinder 5 is used to install the standard lamp 6, as shown in Figure 2. Figure 7 and Figure 8As shown, the segmented heat-conducting cylinder 5 can be fitted onto the standard lamp 6. Specifically, the segmented heat-conducting cylinder 5 is shaped like a cylinder. It includes uniformly divided heat-conducting blocks, meaning the cylinder is configured as a uniformly divided block. This uniform division can be as shown in Figure 2, where the cylinder is divided into 12 heat-conducting blocks along its height. One heat-conducting block is shown as number 5a in Figures 2 and 6, and the other blocks are similarly divided. To avoid redundancy, this will not be elaborated further. These 12 heat-conducting blocks are joined to form the entire segmented heat-conducting cylinder 5, which will be described in detail in the following embodiments. Considering that both the segmented heat-conducting cylinder and the standard lamp are relatively rigid structures, to reduce the impact of rigid contact on their structures, the inner wall of the segmented heat-conducting cylinder 5 is designed to match most of the shape of the standard lamp 6, meaning the standard lamp can be accommodated within the inner wall of the segmented heat-conducting cylinder 5. At least two elastic rings, which can be O-rings, can be configured between the inner wall of the heat-conducting cylinder 5 and the outer wall of the standard lamp 6. In specific implementation, an installation groove for installing the corresponding elastic ring can be provided on the inner wall of the split heat-conducting cylinder 5, so that the corresponding elastic ring is installed in the corresponding installation groove beforehand, and then the split heat-conducting cylinder 5 with elastic rings is fitted onto the standard lamp 6. Alternatively, the corresponding elastic ring can be fitted onto the standard lamp beforehand, and then the split heat-conducting cylinder 5 can be fitted onto the standard lamp 6. In addition, it is worth noting that by configuring the split heat-conducting cylinder 5 into uniformly divided heat-conducting blocks, each heat-conducting block is installed separately on the corresponding area of ​​the standard lamp 6, which facilitates the fitting and installation of the split heat-conducting cylinder 5 onto the standard lamp 6. Thus, at least two O-rings are configured between the inner wall of the split heat-conducting cylinder 5 and the outer wall of the standard lamp 6. Since the split heat-conducting cylinder 5 can be fitted onto the standard lamp 6, both the split heat-conducting cylinder 5 and the standard lamp 6 are provided on the heat-conducting base 11.

[0066] The above embodiments disclose a heat-conducting and vibration-damping structure including a segmented heat-conducting cylinder 5. By configuring the segmented heat-conducting cylinder 5 to include uniformly divided heat-conducting blocks and by arranging at least two elastic rings on the inner wall of the segmented heat-conducting cylinder 5, the uniformly divided heat-conducting blocks on the segmented heat-conducting cylinder 5 can uniformly conduct heat out of their corresponding areas. Furthermore, the elastic rings between the standard lamp 6 and the segmented heat-conducting cylinder 5 can provide a certain buffering effect to improve stability, while the heat from the standard lamp 6 can be transferred to the segmented heat-conducting cylinder 5, which then conducts the heat... The heat is transferred to the heat-conducting base 11, thus achieving the layer-by-layer heat dissipation to improve the thermal conductivity of the standard lamp 6. In addition, by configuring the segmented heat-conducting cylinder 5 to include uniformly divided heat-conducting blocks, it is also convenient to install the segmented heat-conducting cylinder 5 on the standard lamp 6. When it is necessary to increase the conductivity of the heat-conducting blocks, it is also convenient to apply the corresponding thermally conductive elastic medium to the inner wall of each uniformly divided heat-conducting block. This not only improves the service life and working performance of the standard lamp 6, but also improves the stability and service life of the segmented heat-conducting cylinder 5, thereby increasing the success rate of the calibration system.

[0067] In one embodiment, such as Figure 1 As shown, the elastic ring can include at least two elastic rings, that is, at least a first elastic ring 7 and a second elastic ring 8, or more elastic rings. The following embodiment uses a first elastic ring 7 and a second elastic ring 8 as an example. The first elastic ring 7 and the second elastic ring 8 can be configured as O-rings. The inner wall of the split heat conduction cylinder 5 is provided with at least two mounting grooves (not shown in the figure) for installing the corresponding elastic rings. The corresponding mounting grooves are distributed at intervals along the height direction of the split heat conduction cylinder 5. At least one first elastic ring is arranged between the mounting groove of the split heat conduction cylinder 5 and the standard lamp 6. Elastic ring 7 and second elastic ring 8; wherein, the outer diameter of the first elastic ring 7 and the second elastic ring 8 are matched with the inner diameter of the mounting groove, and the inner diameter of the first elastic ring 7 and the second elastic ring 8 are matched with the outer diameter of the standard lamp 6. Specifically, the first elastic ring 7 and the second elastic ring 8 can be installed in the mounting groove corresponding to the split heat conduction cylinder 5, and the first elastic ring 7 and the second elastic ring 8 can be fitted on the corresponding position on the outer wall of the standard lamp 6. In addition, the elastic rings can also provide a certain buffering effect between the inner wall of the split heat conduction cylinder 5 and the outer wall of the standard lamp 6.

[0068] In the above embodiments, at least two mounting grooves for installing corresponding elastic rings are provided on the inner wall of the split heat conduction cylinder 5. The corresponding mounting grooves are distributed at intervals along the height direction of the split heat conduction cylinder 5, so that by configuring at least two elastic rings, the split heat conduction cylinder 5 and the standard lamp 6 have a certain buffering effect at different positions, thereby improving the working stability and service life of the standard lamp 6.

[0069] It should be noted that the first elastic ring 7 and the second elastic ring 8 in the above embodiments are only used for illustrative purposes. In practice, a third elastic ring and a fourth elastic ring may also be included. To avoid redundancy, they will not be elaborated here. In practice, there is no specific limitation, and the configuration can be selected according to actual needs.

[0070] In one embodiment, the segmented heat-conducting cylinder 5 is composed of a metal structure and includes a plurality of heat-conducting blocks evenly divided along the height direction, specifically as shown in Figure 2 and... Figure 5 As shown, the segmented heat-conducting cylinder can be configured to include 12 segmented heat-conducting blocks. These 12 heat-conducting blocks are evenly distributed along the height direction of the segmented heat-conducting cylinder 5. One of the heat-conducting blocks is shown in Figure 2. Figure 5 As shown in Figure 6, number 5a, corresponding fastening holes can also be configured at the bottom of each heat-conducting block (e.g., Figure 4 -5a1 in Figure 6) is used to fasten the split heat-conducting cylinder to the heat-conducting base through the corresponding fastening hole. The specific features of the heat-conducting base in the following embodiment will be described in detail.

[0071] It should be noted that the number of 12 in the above embodiment is only for illustrative purposes, and can be configured to other numbers of heat-conducting blocks. There is no specific limitation here, and the specific configuration can be selected according to the actual scenario.

[0072] In the above embodiments, by configuring the split heat-conducting cylinder 5 as a metal structure, including several heat-conducting blocks evenly divided along the height direction, it is convenient to coat the inner wall of each evenly divided heat-conducting block with a corresponding area of ​​thermally conductive elastic medium. This allows each heat-conducting block to conduct heat evenly, thereby improving the heat dissipation performance of the split heat-conducting cylinder 5. Furthermore, by configuring corresponding fastening holes at the bottom of each heat-conducting block, the split heat-conducting cylinder can be securely installed on the heat-conducting base through the corresponding fastening holes. Specifically, bolts or screws can be used to achieve the fastening installation. This also ensures that even if the standard lamp experiences thermal expansion, each heat-conducting block can be evenly stressed, thereby improving the stability of the split heat-conducting cylinder 5.

[0073] In one embodiment, the thermally conductive vibration isolation structure further includes a high-temperature resistant thermally conductive elastic medium, wherein the thermally conductive elastic medium may be selected from, but is not limited to, silicone rubber, or silicone rubber mixed with other thermally conductive materials, etc., without specific limitation, and can be selected according to the actual scenario.

[0074] Specifically, the split heat-conducting cylinder 5 of the heat-conducting and vibration-damping structure in the above embodiment can be configured as follows:

[0075] It consists of several heat-conducting blocks that are evenly divided along the height direction, and each heat-conducting block is made of metal.

[0076] Alternatively, it may include several uniformly divided heat-conducting blocks, each made of metal, and further include a high-temperature resistant thermally conductive elastic medium. The inner walls of the heat-conducting blocks are each coated with this high-temperature resistant thermally conductive elastic medium. In addition, it should be noted that by selecting a thermally conductive elastic medium such as silicone rubber, the standard lamp can achieve a larger area of ​​buffering inside the split heat-conducting cylinder, further improving the stability of the standard lamp application.

[0077] In the above embodiments, by configuring the segmented heat-conducting cylinder 5 to include a plurality of uniformly divided heat-conducting blocks, it is convenient to coat the inner wall of the corresponding heat-conducting blocks with a thermally conductive elastic medium. This facilitates the coating of the inner wall of each heat-conducting block with the thermally conductive elastic medium, thereby enabling contact and heat conduction between the standard lamp and the heat-conducting blocks in a vacuum environment. This further improves the thermal conductivity of the heat-conducting vibration isolation structure and enhances the stability of the standard lamp during use. Furthermore, based on the above embodiments, at least two elastic rings are correspondingly configured so that the standard lamp 6 also possesses a certain degree of elasticity within the segmented heat-conducting cylinder 5, preventing damage to the standard lamp 6 due to thermal expansion during prolonged operation.

[0078] Based on the above embodiments, each heat-conducting block has a fastening hole at its bottom for securely mounting the split heat-conducting cylinder. In one embodiment, such as... Figure 1 As shown, the heat-conducting base 11 is provided with a heat-conducting base mounting hole 111 and multiple fastening holes (one of the fastening holes is shown in Figure 11). Figure 9 As shown in 11a1, the inner wall of the heat-conducting seat mounting hole 111 is provided with a protruding structure 112 that penetrates the heat-conducting seat mounting hole 111. The bottom of the split heat-conducting cylinder 5 is provided with a connecting structure 51 that matches the protruding structure 112. The connecting structure 51 passes through the protruding structure 112 and abuts against the heat-conducting seat 11. The protruding structure 112 can be understood as a "stop" structure, which can block the movement of the split heat-conducting cylinder 5 through the "stop" structure, thereby limiting the movement path of the split heat-conducting cylinder 5. This ensures that the split heat-conducting cylinder 5 will not squeeze the standard lamp. The split heat-conducting cylinder 5 and the heat-conducting seat 11 also ensure a small gap fit between the standard lamp and the split heat-conducting cylinder 5 through the "stop".

[0079] The connecting structure 51 is provided with a plurality of fastening holes at intervals and evenly distributed, corresponding to each heat-conducting block. That is, the number of fastening holes on the heat-conducting base 11 corresponds to the number of fastening holes on the split heat-conducting cylinder 5. For example, if the split heat-conducting cylinder 5 includes 12 heat-conducting blocks, the connecting structure 51 is provided with 12 fastening holes at intervals and evenly distributed, corresponding to each heat-conducting block. The fastening hole of each heat-conducting block is connected to the fastening hole on the heat-conducting base one by one by the corresponding fastener. Specifically, the heat-conducting base mounting hole 111 can be opened in the middle of the heat-conducting base 11, and a plurality of fastening holes can be opened evenly distributed on the side of the heat-conducting base mounting hole 111, so as to install and connect one by one by configuring a plurality of fasteners to pass through the fastening holes on the split heat-conducting cylinder and the fastening holes on the heat-conducting base.

[0080] In the above embodiments, by configuring heat-conducting base mounting holes 111 and multiple fastening holes on the heat-conducting base 11, and configuring corresponding connecting structures 51 and multiple fastening holes that match the corresponding multiple fastening holes for the split heat-conducting cylinder 5, a tight connection between the split heat-conducting cylinder 5 and the heat-conducting base 11 can be achieved. It can be understood that, based on the fastening holes configured on each heat-conducting block on the split heat-conducting cylinder, even if the standard lamp experiences thermal expansion, the force on each heat-conducting block on the heat-conducting base 11 can be uniform due to the installation connection between each heat-conducting block and the fastening holes on the heat-conducting base 11, thereby improving the stability of the split heat-conducting cylinder 5. Furthermore, the "stop" structure configured on the heat-conducting base 11 can also improve the safety of applying the thermally conductive vibration-damping structure to the standard lamp.

[0081] In one embodiment, such as Figure 1 As shown, the thermally conductive vibration-damping structure also includes a washer 9. The washer 9 has a convex cross-section, meaning it comprises a wide circular ring with a first outer diameter and a wide circular ring with a second outer diameter. These two wide circular rings can be integrally formed or formed by post-processing pressing. The first and second outer diameters are different in size. The convex-shaped washer 9 rests inverted against the raised structure. The washer 9 is configured to contact the bottom structure of the standard lamp 6. Specifically, the washer 9 can be made of polytetrafluoroethylene (PTFE), which allows it to not only provide cushioning performance but also withstand high temperatures.

[0082] In the above embodiments, by configuring a washer 9 for the thermally conductive vibration isolation structure and configuring the washer 9 as a wide circular ring with different outer diameters, the convex washer 9 is inverted and abuts against the protruding structure. The washer 9 is configured to contact the bottom structure of the standard lamp 6, so that the washer 9 can further provide a certain buffering effect for the standard lamp 6, thereby improving the stability and service life of the standard lamp using the thermally conductive vibration isolation structure.

[0083] In practical applications, the inventors also discovered that the thermally conductive vibration-damping structure of the related technology lacks a vibration-damping element, resulting in poor stability during use. To further address the aforementioned technical problem, in one embodiment, such as... Figure 1 and Figure 8 As shown, the thermally conductive vibration isolation structure may further include an electrical box, which includes an upper cover plate 4, a lower cover plate 1, an electrical box frame 2 disposed between the upper cover plate 4 and the lower cover plate 1, and multiple vibration isolation components 10, wherein:

[0084] The circuit board 3 is disposed between the upper cover plate 4 and the lower cover plate 1 of the electrical box via the electrical box frame 2. The upper cover plate 4, the circuit board 3, and the lower cover plate 1 of the electrical box are all provided with through holes through which the split heat conduction cylinders 5 pass. The split heat conduction cylinders 5 can pass through the corresponding through holes, and the bottom of the split heat conduction cylinders 5 abuts against the heat conduction base 11. Multiple vibration isolation components 10 are evenly distributed between the lower cover plate 1 of the electrical box and the heat conduction base 11. As shown in Figure 2, the multiple vibration isolation components 10 mentioned in the above embodiment can be configured with 4 vibration isolation components 10 or other numbers of vibration isolation components 10 in specific implementation. The vibration isolation components can be configured to include a combination structure such as multiple vibration isolation pads, and as shown in Figure 2, the 4 vibration isolation components are symmetrically and evenly distributed at the position of the top projection of the lower cover plate 1 of the electrical box.

[0085] In the above embodiments, by further configuring an electrical box for the thermally conductive vibration isolation structure, the structure can be installed within the electrical box, further improving its integration. Furthermore, the even distribution of multiple vibration isolation components 10 between the lower cover plate 1 of the electrical box and the thermally conductive base 11 allows each vibration isolation component 10 to be positioned at different locations, and the vibration isolation pads included in each component 10 can further enhance the buffering performance of the thermally conductive vibration isolation structure, thereby improving its stability and service life.

[0086] In one embodiment, one of the vibration isolation components 10 is used for illustration, such as Figure 3 , Figure 11 As shown in Figure 12, the vibration isolation assembly 10 in the above embodiment includes a sleeve 101, a first vibration isolation pad 102, a second vibration isolation pad 103, and a gasket 104 arranged sequentially, wherein:

[0087] like Figure 7 and Figure 9 As shown, the heat-conducting base 11 is also provided with vibration isolation mounting hole 11b, and the lower cover plate 1 of the electrical box is also provided with lower cover plate mounting hole (not shown in the figure). The sleeve 101 is located below the lower cover plate 1 of the electrical box. The sleeve 101 has a through hole, and the mounting hole of the lower cover plate 1 of the electrical box is connected to the through hole of the sleeve 101.

[0088] like Figure 11 and Figure 12bAs shown, the first vibration isolation pad includes a first ring 102a and a second ring 102b. The first ring 102a and the second ring 102b can be an integral structure or a separate structure, which is not limited in any particular way. Preferably, they can be configured as an integral structure. Specifically, the diameter of the first ring 102a is larger than the diameter of the second ring 102b. The first ring 102a is sleeved on the sleeve 101 and abuts against the heat-conducting seat 11. The second ring 102b is sleeved on the sleeve 101 and abuts against the inner wall of the vibration isolation mounting hole.

[0089] The second vibration isolation pad includes a third ring, that is, the second vibration isolation pad can be configured in the shape of a ring. The diameter of the third ring is larger than the diameter of the second ring 102b. Specifically, the diameter of the third ring can be equal to the diameter of the first ring 102a. The third ring is sleeved on the sleeve and the upper surface of the third ring also abuts against the bottom of the heat-conducting seat and the bottom of the second ring 102b respectively.

[0090] The bottom of the third ring is flush with the bottom of the sleeve, and the gasket is located below the third ring and the sleeve;

[0091] The fastener can pass through the sleeve 101 (which also passes through the vibration isolation mounting hole 11b of the heat conduction seat 11, with the sleeve 101 located between the vibration isolation mounting hole 11b and the fastener) and the lower cover mounting hole in sequence. The fastening head of the fastener can also abut against the bottom of the gasket 104. The fastening head of the fastener can serve as a support base. Alternatively, a corresponding buffer pad can be configured on the fastening head of the fastener to further improve the buffering performance of the support base.

[0092] In the above embodiments, by configuring sleeves 101, first vibration isolation pads 102, second vibration isolation pads 103 and gaskets 104 sequentially on each vibration isolation component 10, multiple flexible vibration isolation links can be passed between the standard lamp 6 and the thermally conductive vibration isolation structure, so as to further improve the heat insulation performance of the standard lamp 6 installed in the thermally conductive vibration isolation structure.

[0093] In one embodiment, such as Figure 1 As shown, the thermally conductive and vibration-damping structure also includes a mounting space for the circuit board 3 used to mount the standard lamp 6. This mounting space is the internal space of the electrical box upper cover plate 4, the electrical box lower cover plate 1, and the electrical box frame 2 assembly, wherein:

[0094] At least a first mounting structure 21 and a second mounting structure 22 extend from both sides of the electrical box frame 2, and the two sides of the circuit board 3 can be correspondingly mounted on the first mounting structure 21 and the second mounting structure 22. Specifically, through holes can be opened on the circuit board 3, and then the circuit board 3 can be inserted through the through holes onto the first mounting structure 21 and the second mounting structure 22, so that the circuit board 3 can be integrated into the internal space of the electrical box. This helps to reduce the installation space, make the structure more compact, and improve the integration of the standard lamp 6 in practical applications.
