Description

Technical Field

[0001] This application relates to the field of spacecraft thermal control technology, and more specifically, to an infrared heat cage baffle module and an infrared heat cage system. Background Technology

[0002] Spacecraft typically orbit in the space environment outside the atmosphere. This environment is characterized by low temperatures, vacuum, and a black background, significantly different from the Earth's environment. The function of a spacecraft's thermal control system is to control the heat exchange process between the spacecraft's interior and exterior, providing a suitable temperature environment for its instruments and equipment, based on the spacecraft's flight requirements and the internal and external heat loads it experiences during operation. To verify the functionality of the thermal control system, and also to verify that the spacecraft's instruments and the entire spacecraft system can operate normally in a vacuum thermal environment, a ground-based test system that closely approximates the conditions of the space environment needs to be built.

[0003] The aforementioned ground-based test system needs to simulate the high vacuum and cold black background of the space environment, while providing the test spacecraft with corresponding external thermal conditions. The external heat flux of a spacecraft in orbit mainly consists of three parts: solar irradiance heat flux, Earth albedo heat flux, and Earth infrared heat flux. During ground-based simulations, the absorption heat flux method is typically used to simulate the intensity of radiative heat flux absorbed by the surface of the test spacecraft. This method converts the external heat flux to be simulated into infrared radiation.

[0004] like Figure 1 The infrared heat cage is the most commonly used infrared heater for simulating heat absorption on spacecraft surfaces. Its main components are a frame 02 and heating strips 01 mounted on the frame 02. The heat absorption on different surfaces of a spacecraft is typically simulated independently by multiple heat cages. Baffles are placed within the radiative heating areas of adjacent infrared heat cages to block the radiative heating heat flow, thereby reducing the impact of radiative heating on a particular surface of the spacecraft from nearby infrared heat cages. However, the current baffle structure used in infrared heat cages is still insufficient to meet the accuracy requirements for simulating the ground thermal environment. Summary of the Invention

[0005] The purpose of this application is to provide an infrared heat cage baffle module and an infrared heat cage system to address at least one of the technical problems involved in the background art.

[0006] To achieve the above objectives, this application adopts the following technical solution: One aspect of this application provides an infrared heat cage baffle module, including a base baffle and a radiating baffle installed on the base baffle. The radiating baffle and the base baffle are arranged in parallel, with a gap between them. The base baffle has a first reflective surface, and the radiating baffle has a second reflective surface. The second reflective surface faces the base baffle. The infrared heat cage baffle module is used to be disposed between two adjacent infrared heat cages, and the first reflective surface faces the infrared heat cage with a larger heat flux.

[0007] Optionally, the radiation baffle includes a plate body and a connecting part, the connecting part being angled to the plate body, one end of the base baffle being an external end and the other end being a connecting end in a first direction, the connecting end being connected to the connecting part, and the first direction being parallel to the base baffle.

[0008] The beneficial effects of this technical solution are as follows: that is, the radiation baffle can be made by bending a plate or plate structure, and the two parts formed after bending are the plate body and the connecting part, respectively. The radiation baffle can be connected to the outside through the connecting part, which facilitates the manufacturing of radiation baffle and infrared heat cage baffle modules.

[0009] Optionally, the infrared heat cage baffle module provided in this application includes at least two radiation baffles arranged parallel to each other, each radiation baffle is arranged in a second direction, and a gap is left between each pair of adjacent radiation baffles, the second direction being perpendicular to the base baffle.

[0010] The beneficial effects of this technical solution are as follows: The infrared heat cage baffle module provided in this application is equipped with at least two radiation baffles, which can more effectively improve the shielding effect of the infrared heat cage baffle module on the radiative heat exchange between two adjacent infrared heat cages, thereby reducing the adverse impact of radiative heat exchange between two adjacent infrared heat cages on the accuracy of ground thermal environment simulation.

[0011] Optionally, the radiating baffle located near the base baffle is connected to the base baffle through its connecting portion, and the radiating baffle located away from the base baffle in two adjacent radiating baffles is fixed to the radiating baffle located near the base baffle through its connecting portion.

[0012] The beneficial effect of this technical solution is that it makes the area occupied by the connection part of the radiation baffle relatively small, which helps to reduce the manufacturing cost of the infrared heat cage baffle module.

[0013] Optionally, each of the connecting portions is distributed in the second direction and staggered in the first direction.

[0014] The beneficial effect of this technical solution is that, in the direction perpendicular to the base baffle, as one connecting part is gradually moved away from the base baffle and placed closer to the connecting end, another connecting part is placed closer to the external end, and another connecting part is placed closer to the connecting end, and so on, forming a structure similar to a snake structure, so as to achieve a better heat shielding effect.

[0015] Optionally, the base baffle and each of the radiation baffles are integrally formed.

[0016] The beneficial effect of this technical solution is that it can improve the manufacturing efficiency of infrared heat cage baffle modules.

[0017] Optionally, the base baffle includes a third reflective plate surface, which is disposed facing the radiation baffle.

[0018] The beneficial effect of this technical solution is that, in other words, the third reflector surface is set opposite to the second reflector surface, which makes it easier to retain heat between the third reflector surface and the second reflector surface, making it difficult for heat to be transferred out of the infrared heat cage baffle module. This effectively improves the shielding effect of the infrared heat cage baffle module on the radiative heat transfer between two adjacent infrared heat cages, thereby reducing the adverse impact of radiative heat transfer between two adjacent infrared heat cages on the accuracy of ground thermal environment simulation.

[0019] Optionally, the radiation baffle includes a fourth reflective surface, which is disposed away from the base baffle.

[0020] The beneficial effects of this technical solution are as follows: when multiple radiation baffles are used, the second and fourth reflective surfaces between adjacent radiation baffles can, to a certain extent, limit the heat between the second and fourth reflective surfaces, making it difficult for the heat to be transferred out of the infrared heat cage baffle module. This effectively improves the shielding effect of the infrared heat cage baffle module on the radiative heat transfer between two adjacent infrared heat cages, thereby reducing the adverse impact of radiative heat transfer between two adjacent infrared heat cages on the accuracy of ground thermal environment simulation.

[0021] Optionally, the base baffle further includes a first substrate, on which a heat-reflecting film is adhered to form a first reflective plate surface and a third reflective plate surface; and / or, the radiation baffle includes a second substrate, on which a heat-reflecting film is adhered to form a second reflective plate surface and a fourth reflective plate surface.

[0022] The beneficial effects of this technical solution are that the heat-reflecting film can effectively reflect heat radiation, thereby improving the shielding effect of the infrared heat cage baffle module on the radiative heat exchange between two adjacent infrared heat cages, and achieving the goal of reducing the adverse impact of radiative heat exchange between two adjacent infrared heat cages on the accuracy of ground thermal environment simulation.

[0023] Another aspect of this application provides an infrared heat cage system, including a first infrared heat cage, a second infrared heat cage, and an infrared heat cage baffle module provided in this application. The first infrared heat cage is vertically connected to the second infrared heat cage, and the heat flux of the first infrared heat cage is greater than that of the second infrared heat cage. The first reflector is disposed facing the first infrared heat cage.

[0024] The technical solution provided in this application can achieve at least one of the following beneficial effects: The infrared heat cage baffle module and infrared heat cage system provided in this application can initially reflect the thermal radiation generated by the infrared heat cage on the side with greater heat flux by setting a first reflective plate. When the base baffle absorbs part of the radiant heat and continues to transfer heat to the radiant baffle, the second reflective plate reflects the thermal radiation again, blocking the thermal radiation generated by the infrared heat cage on the side with greater heat flux. This effectively improves the shielding effect of the infrared heat cage baffle module on the radiative heat transfer between two adjacent infrared heat cages, thereby reducing the adverse impact of radiative heat transfer between two adjacent infrared heat cages on the accuracy of ground thermal environment simulation.

[0025] The additional technical features and advantages of this application will become more apparent from the following description or from practical application. Attached Figure Description

[0029] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] In actual on-orbit operation, Spacecraft 05 often has a surface directly exposed to sunlight. The heat flux density absorbed on this surface differs significantly from that on the other surfaces. When Spacecraft 05 participates in ground-based vacuum thermal tests, the ground test system needs to maximize the realism and accuracy of the space heat flux simulation. In this situation, traditionally designed baffles offer limited protection. For example... Figure 1As shown, in the prior art, when the design heat flux of the adjacent first infrared heat cage 07 differs significantly from that of the second infrared heat cage 03 (i.e., the design value of the heat flux absorbed by the first spacecraft surface 06 is much higher than the design value of the heat flux absorbed by the adjacent second spacecraft surface 04), the first infrared heat cage 07 raises the temperature of the baffle through radiative heating, thereby increasing the actual temperature difference between the baffle and the second spacecraft surface 04. This leads to an increase in the amount of radiative heating from the baffle to the second spacecraft surface 04, weakening the shielding effect of the baffle on radiative heat transfer between the two adjacent infrared heat cages, and thus adversely affecting the accuracy of ground thermal environment simulation.

[0033] like Figures 2 to 4 As shown, one aspect of this application provides an infrared heat cage baffle module 12, including a base baffle 10 and a radiation baffle 13 installed on the base baffle 10. The radiation baffle 13 and the base baffle 10 are arranged in parallel, with a gap between the base baffle 10 and the radiation baffle 13. The base baffle 10 has a first reflective plate surface, and the radiation baffle 13 has a second reflective plate surface. The second reflective plate surface faces the base baffle 10. The infrared heat cage baffle module 12 is used to be disposed between two adjacent infrared heat cages, and the first reflective plate surface is used to face the infrared heat cage with a larger heat flux.

[0034] The infrared heat cage baffle module 12 provided in this application can initially reflect the thermal radiation generated by the infrared heat cage on the side with greater heat flow by setting a first reflective plate. When the base baffle 10 absorbs part of the radiant heat and continues to transfer heat to the radiative baffle 13, the second reflective plate reflects the thermal radiation again, blocking the thermal radiation generated by the infrared heat cage on the side with greater heat flow again. This effectively improves the shielding effect of the infrared heat cage baffle module 12 on the radiative heat transfer between two adjacent infrared heat cages, thereby reducing the adverse impact of radiative heat transfer between two adjacent infrared heat cages on the accuracy of ground thermal environment simulation.

[0035] Optionally, the radiation baffle 13 includes a plate body 11 and a connecting part 09. The connecting part 09 is angled to the plate body 11. In a first direction, one end of the base baffle 10 is an external connection end, and the other end is a connecting end. The connecting end is connected to the connecting part 09. The first direction is parallel to the base baffle 10. The angled arrangement between the connecting part 09 and the plate body 11 means that the connecting part 09 and the plate body 11 form an obtuse angle, a right angle, or an acute angle. That is, the radiation baffle 13 can be made by bending a plate or plate structure, resulting in two parts: the plate body 11 and the connecting part 09. The radiation baffle 13 can be connected to an external connection through the connecting part 09, which facilitates the manufacturing of the radiation baffle 13 and the infrared heat cage baffle module 12. Alternatively, a connector independent of the radiation baffle 13 can be used to connect the radiation baffle 13 to the base baffle 10.

[0036] Optionally, the infrared heat cage baffle module 12 provided in this application includes at least two radiation baffles 13 arranged parallel to each other. Each of the radiation baffles 13 is arranged in a second direction, and a gap is left between each two adjacent radiation baffles 13. The second direction is perpendicular to the base baffle 10. When the design heat flux of the first infrared heat cage 07 and the second infrared heat cage 03 differs significantly (i.e., the design value of the heat flux absorbed by the first spacecraft surface 06 is much higher than the design value of the heat flux absorbed by the second spacecraft surface 04), the first infrared heat cage 07 raises the temperature of the adjacent base baffle 10 through radiative heating. At this time, although there is a large temperature difference between the base baffle 10 and the second spacecraft surface 04 with a lower design temperature, there is no direct radiative heat transfer relationship between the base baffle 10 and the second spacecraft surface 04. The heat radiation transfer process on the base baffle 10 is shielded by each layer of radiative baffle 13, and finally radiative heat transfer occurs between the outermost radiative baffle 13 and the second spacecraft surface 04. In this heat transfer process, the thermal interference effect of the infrared radiation heating of the first infrared heat cage 07 on the second infrared heat cage 03 is greatly reduced through the accumulation of layer thermal resistance. The infrared heat cage baffle module 12 provided in this application is provided with at least two radiation baffles 13, which can more effectively improve the shielding effect of the infrared heat cage baffle module 12 on the radiative heat transfer between two adjacent infrared heat cages, thereby reducing the adverse impact of radiative heat transfer between two adjacent infrared heat cages on the accuracy of ground thermal environment simulation. In the embodiments of this application, the number of radiation baffles 13 can be set as needed, for example, it can be 2 to 10, such as 3, 5 or 8.

[0037] If all the connecting portions 09 of the radiation baffles 13 are directly fixed to the base baffle 10, the longer the connecting portion 09 of the radiation baffle 13 located further away from the base baffle 10, the higher the manufacturing cost. Optionally, in this embodiment, the radiation baffle 13 located near the base baffle 10 is connected to the base baffle 10 via its connecting portion 09, and the radiation baffle 13 located further away from the base baffle 10 among two adjacent radiation baffles 13 is fixed to the radiation baffle 13 located closer to the base baffle 10 via its connecting portion 09. This makes the area occupied by the connecting portion 09 of the radiation baffle 13 relatively small, which helps to reduce the manufacturing cost of the infrared heat cage baffle module 12.

[0038] Optionally, each of the connecting portions 09 is distributed in the second direction and staggered in the first direction. That is, in the direction perpendicular to the base baffle 10, as one connecting portion 09 moves away from the base baffle 10, it is positioned closer to the connecting end, another connecting portion 09 is positioned closer to the external end, and another connecting portion 09 is positioned closer to the connecting end, and so on, forming a structure similar to a serpentine structure.

[0039] Optionally, the base baffle 10 and each of the radiation baffles 13 are integrally formed. This can improve the manufacturing efficiency of the infrared heat cage baffle module 12. The base baffle 10 and the radiation baffles 13, as well as each of the radiation baffles 13, can also be connected by welding.

[0040] Optionally, the base baffle 10 includes a third reflective plate surface, which faces the radiation baffle 13. That is, the third reflective plate surface is positioned opposite to the second reflective plate surface, facilitating heat retention between them and making it difficult for heat to escape from the infrared heat cage baffle module 12. This effectively improves the shielding effect of the infrared heat cage baffle module 12 on radiative heat transfer between two adjacent infrared heat cages, thereby reducing the adverse impact of radiative heat transfer between two adjacent infrared heat cages on the accuracy of ground thermal environment simulation.

[0041] Optionally, the radiation baffle 13 includes a fourth reflective surface, which is disposed away from the base baffle 10. When multiple radiation baffles 13 are used, the second and fourth reflective surfaces between adjacent radiation baffles 13 can, to a certain extent, confine heat between the second and fourth reflective surfaces, making it difficult for heat to be transferred out of the infrared heat cage baffle module 12. This effectively improves the shielding effect of the infrared heat cage baffle module 12 on radiative heat transfer between two adjacent infrared heat cages, thereby reducing the adverse impact of radiative heat transfer between two adjacent infrared heat cages on the accuracy of ground thermal environment simulation.

[0042] Optionally, the base baffle 10 further includes a first substrate, on which a heat-reflective film is adhered to form the first reflective surface and the third reflective surface; and / or, the radiation baffle 13 includes a second substrate, on which a heat-reflective film is adhered to form the second reflective surface and the fourth reflective surface. The heat-reflective film can effectively reflect thermal radiation, thereby improving the shielding effect of the infrared thermal cage baffle module 12 on the radiative heat transfer between two adjacent infrared thermal cages, and achieving the purpose of reducing the adverse impact of radiative heat transfer between two adjacent infrared thermal cages on the accuracy of ground thermal environment simulation. In this embodiment, the heat-reflective film can be an aluminum-plated film or a silver-plated film, and the first substrate and the second substrate can be non-metallic thin-walled materials with low thermal conductivity. The base baffle 10 can be an aluminum alloy sheet, and the first reflective plate surface and / or the third reflective plate surface are formed by polishing the surface of the base baffle 10. The radiation baffle 13 can be an aluminum alloy sheet or an aluminum alloy plate, and the second reflective plate surface and / or the fourth reflective plate surface are formed by polishing the surface of the first substrate. Regardless of whether a heat-reflective film is used or polishing is performed, the reflectivity for infrared radiation energy can be much greater than the absorptivity, and the infrared hemispherical emissivity of the surface can be reduced and the shielding performance of radiation heat transfer can be improved. The base baffle 10 and each of the radiation baffles 13 can be integrally formed from aluminum alloy sheets. The base baffle 10 and the radiation baffles 13 should be as thin as possible to reduce the heat conduction between different baffles.

[0043] Another aspect of this application provides an infrared heat cage system, including a first infrared heat cage 07, a second infrared heat cage 03, and an infrared heat cage baffle module 12 provided in the embodiments of this application. The first infrared heat cage 07 is vertically connected to the second infrared heat cage 03, and the heat flow of the first infrared heat cage 07 is greater than the heat flow of the second infrared heat cage 03. The surface of the first reflector plate is disposed facing the first infrared heat cage 07.

[0044] The infrared heat cage system provided in this application is implemented using the infrared heat cage baffle module 12 provided in this application. By setting a first reflective plate, the thermal radiation generated by the infrared heat cage on the side with greater heat flux can be initially reflected. When the base baffle 10 absorbs part of the radiant heat and continues to transfer heat to the radiant baffle 13, the second reflective plate reflects the thermal radiation again, blocking the thermal radiation generated by the infrared heat cage on the side with greater heat flux again. This effectively improves the shielding effect of the infrared heat cage baffle module 12 on the radiative heat transfer between two adjacent infrared heat cages, thereby reducing the adverse impact of radiative heat transfer between two adjacent infrared heat cages on the accuracy of ground thermal environment simulation.

[0045] Preferably, the base baffle 10 includes a connecting end fixed at the intersection of the first infrared heat cage 07 and the second infrared heat cage 03, and the radiation baffle 13 is located within the radiation heating area of ​​the second infrared heat cage 03.

[0046] The infrared heat cage baffle module 12 preferably includes a connecting plate 08, and the outer end of the base baffle 10 is fixed to the infrared heat cage through the connecting plate 08.

[0047] In this embodiment, the infrared heat cage baffle module 12 can also be a box-shaped structure, with a sealed vacuum cavity formed inside the box-shaped structure. The base baffle 10 and the radiation baffle 13 are the side walls of the box-shaped structure. When the infrared heat cage baffle module 12 includes multiple radiation baffles 13, each radiation baffle 13 is arranged in the vacuum cavity, thereby shielding the radiation heat exchange between two adjacent infrared heat cages through the vacuum cavity and each baffle.

[0048] In this embodiment, the base baffle 10 and the radiation baffle 13 can be connected by a hinge with a damping effect. When the infrared heat cage baffle module 12 includes multiple radiation baffles 13, adjacent radiation baffles 13 can also be connected by a hinge with a damping effect, thereby changing and selecting the gap size between each baffle to obtain a better shielding effect for the radiation heat transfer of two adjacent infrared heat cages. The outer end of the base baffle 10 can also be installed onto the infrared heat cage by a hinge with a damping effect.

[0049] 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. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
