Description

Technical Field

[0001] The present invention relates to the technical field of spacecraft thermal control, and in particular to a bidirectional convection single-phase fluid circuit system and a one-dimensional unfolding radiator. Background Art

[0002] As the flight orbit environment of spacecraft becomes increasingly complex, the functions of carrying payloads become increasingly diverse and the operation precision is high, which increases the overall thermal power consumption of spacecraft. In order to meet the thermal control requirements of payload operation and the high precision of the structural platform, the original traditional passive thermal control method can no longer meet the requirements. Although the radiator heat dissipation method gradually used can enhance the heat dissipation capacity, how to increase the radiator area to break through the fairing envelope size, how to arrange more efficient heat dissipation channels on the same limited size area after deployment, and how to more reliably solve the balance between high-sealing fluid pipelines and deployment torque have become issues to be further resolved.

[0003] The existing Chinese patent with publication number CN103274061B discloses a heat pipe-fluid loop coupled heat radiator for spacecraft. It is a plate-type radiator purely attached to the structural platform, does not have the expansion function, and is only a heat pipe, and the heat pipe is connected to the fluid pipelines on both sides by welding or gluing. This method does not make the fluid pipeline form a normal loop, and there is still room for improvement in heat dissipation capacity and thermal control.

Both are S-shaped layouts with unidirectional single-phase fluid pipelines, and this layout has not further developed the state utilization rate of the cooling fluid direction of the single-phase fluid.

The high-temperature outlet 222 of the inner single-phase fluid 22 is arranged correspondingly; the external piping system 3 of the radiator plate includes a low-temperature single-phase fluid pipeline 31 and a high-temperature single-phase fluid pipeline 32. The outlet of the low-temperature single-phase fluid pipeline 31 is respectively connected to the low-temperature inlet 221 of the inner single-phase fluid and the low-temperature inlet 212 of the outer single-phase fluid, and the inlet of the high-temperature single-phase fluid pipeline 32 is respectively connected to the high-temperature outlet 211 of the outer single-phase fluid and the high-temperature outlet 222 of the inner single-phase fluid. The heat exchanger, the low-temperature single-phase fluid pipeline 31, the piping system 2 inside the radiator plate and the high-temperature single-phase fluid pipeline 32 are connected in sequence to form a loop.

[0063] The piping system 2 inside the radiator plate is installed in the same dimensional plane as the radiator structural plate 1, and the piping system 3 outside the radiator plate is installed outside the radiator structural plate 1. The external single-phase fluid high-temperature outlet 211, the internal single-phase fluid low-temperature inlet 221, the internal single-phase fluid high-temperature outlet 222, and the external single-phase fluid low-temperature inlet 212 are arranged in sequence on the same side of the radiator structural plate 1. The external pipeline 21 and the internal pipeline 22 are arranged in parallel and the temperature control area of ​​the two is evenly distributed.

[0067] Example 2

[0068] Based on Example 1, Figure 6-14 As shown, a one-dimensional unfolded radiator provided according to the present invention adopts the bidirectional convection single-phase fluid circuit system of Example 1, and also includes a radiator structural plate 1, a radiator suspension support structure 4 and a hinge 6. The radiator structural plate 1 is a skeleton-type sandwich lightweight reinforcement structure, including two bonded upper and lower layers of skin and an intermediate layer. The skin can be made of aluminum alloy or carbon fiber; the radiator plate internal pipeline system 2 is embedded in the intermediate layer, and the overall structure of the radiator structural plate 1 is symmetrical about its central axis, and the overall pipeline system adopts a high-sealing welding process. Two radiator suspension support structures 4 and two hinges 6 are symmetrically arranged on the same side of the radiator structure plate 1. The radiator plate external pipeline system 3 and the radiator suspension support structure 4 are both arranged on the same side of the radiator structure plate 1. A channel is formed inside the radiator suspension support structure 4. One end of the two radiator suspension support structures 4 are respectively connected to the low-temperature single-phase fluid pipeline 31 and the high-temperature single-phase fluid pipeline 32, and the other end of the two radiator suspension support structures 4 are respectively connected to the heat exchanger; the radiator suspension support structure 4 includes a rotating joint 41 and a floating support 42. The rotating joint 41 and the floating support 42 cooperate to form a rotating pair. The central axes of the two rotating joints 41 are coaxially arranged with the rotating axes of the two hinges 6. The radiator suspension support structure 4 and the hinge 6 are both tightly connected to the radiator structure plate 1, and the radiator structure plate 1 can rotate around the central axis of the rotating joint 41. The two-way converging and beaming fluid outside the radiator structure plate 1 is rigidly connected to the radiator suspension support structure 4 and is coaxial with the hinge 6 of the radiator structure plate 1.

The straight pipeline 23 of the outer pipe system 3 of the radiator plate is arranged parallel or vertically to the composite rectangular tube 11, and a plurality of composite rectangular tubes 11 cooperate to form the support frame of the radiator structure plate 1. The pyrotechnic unlocking port 14 and the hinge mounting seat of the radiator structure plate 1 are respectively provided with beveled support reinforcement rectangular tubes. The composite rectangular tube 11 covers the overall shape of the radiator structure plate 1, and the composite rectangular tube 11 at the corner of the shape is plugged and glued through the right-angle joint 121, and the inside is plugged and glued through the three-way right-angle joint 122. The composite rectangular tube 11 is evenly distributed horizontally and vertically between the outer pipe 21 and the outer frame, and between the inner pipe 22 and the outer pipe 21. The composite rectangular tube at the pyrotechnic unlocking port 14 and the hinge mounting seat is reinforced with beveled supports; the cross-supporting parts are all glued and plugged in, and structural adhesive is used for gluing.

[0070] The radiator suspension support structure 4 is symmetrically arranged about the central axis of the radiator structure plate 1. A plate structure protrusion 16 is formed in the middle of one side where the radiator structure plate 1 is connected to the radiator suspension support structure 4. Composite material embedded blocks 13 are symmetrically arranged on the plate structure protrusion 16. The composite material embedded blocks 13 include suspension support structure embedded blocks 131 and hinge embedded blocks 132. The suspension support structure embedded blocks 131 are symmetrically arranged at both ends of the plate structure protrusion 16, and the hinge embedded blocks 132 are arranged on the inner side of the suspension support structure embedded blocks 131, forming a bilateral layout symmetrical about the central axis of the radiator structure plate 1. The composite material embedded blocks 13 and the frame of the radiator structure plate 1 are in a plug-in form, and structural adhesive is used for bonding. The hinge embedded block 132 is tightly connected to the hinge 6, and the suspension support structure embedded block 131 is tightly connected to the rotating joint 41.

[0071] The low-temperature single-phase fluid pipeline 31 is arranged on the lower side of the plate structure protrusion 16, and the high-temperature single-phase fluid pipeline 32 is arranged on the upper side of the plate structure protrusion 16. The low-temperature single-phase fluid pipeline 31 and the high-temperature single-phase fluid pipeline 32 are arranged in parallel with the radiator structure plate 1, and the distance between the two and the radiator structure plate 1 is consistent. The two ends of the pipelines of the low-temperature single-phase fluid pipeline 31 and the high-temperature single-phase fluid pipeline 32 are respectively connected to the pipeline system 2 in the radiator plate. The middle parts of the pipelines of the low-temperature single-phase fluid pipeline 31 and the high-temperature single-phase fluid pipeline 32 are respectively provided with three-way joints 33 connected to the radiator suspension support structure 4. The through holes at both ends of the three-way joint 33 are arranged on the low-temperature single-phase fluid pipeline 31, and the third through hole in the middle is horizontally connected to the outside with a pipeline, and then extends downward through a two-way joint through the pipeline to be connected to one end of the radiator suspension support structure 4, thereby communicating with the internal channel of the radiator suspension support structure 4, and the three-way joints 33 on the pipelines of the high-temperature single-phase fluid pipeline 32 are similarly arranged.

The tee-shaped bundle positions of the high and low-temperature single-phase fluid circuits are symmetrical in height to the middle surface of the radiator structure plate 1 in the same plane; symmetrical to the center of the radiator structure plate 1 in the left and right; and flush with the side. The pipelines before and after the bundle convergence shall not interfere with the unfolded states of the radiator structure plate 1, and the minimum area value length of the welding influence zone shall be selected based on the normal space distance of the radiator structure plate 1 and the length of the pipeline welding section.

[0072] The high and low temperature single-phase fluid circuit three-way clusters at both ends of the radiator structural plate 1 are connected to one end of the rotating joint 41 with a multi-L-shaped pipeline space running outward, and the other end of the rotating joint 41 is connected to the corresponding hot and cold fluids of the heat exchanger. The layout of the radiator suspension support structure 4 is symmetrical with respect to the center of the radiator structural plate 1, and the pipelines connected to the two ends of the radiator suspension support structure 4 must be coaxial with the hinges, and work together to complete the one-dimensional 90° expansion of the radiator after unlocking. That is, during the folding and unfolding of the radiator structural plate 1, the two hinges 6 must be coaxial with the confluence outlet of the high and low temperature fluid pipelines and the connected rotating joint 41.

[0073] The rotary joint 41 includes an inner channel 411 and an outer channel 412. One end of the inner channel 411 is inserted into one end of the outer channel 412 and the two are sealed and connected by a sealing ring 413.

Flanges and pin holes are provided at the ends of the inner channel 411 and the outer channel 412 close to the outside, and sealing rings 413 are placed in two grooves in the inner cavity of the outer channel 412 pipe section. The connection design of the inner and outer channel pipe sections and the fluid pipeline section is a screw connection form of a rigid ball head sealing nozzle 414 and a sealing screw 415. The rotation of the rotary joint 41 needs to be balanced with the torque of the hinge 6.

[0075] A plurality of clamp brackets 5 for supporting the pipes of the radiator plate external pipe system 3 are arranged on the side of the plate structure protrusion 16. The clamp brackets 5 and the radiator plate external pipe system 3 are arranged on the same vertical plane, and the plurality of clamp brackets 5 are arranged symmetrically about the radiator structure plate 1, and the plurality of clamp brackets 5 are arranged symmetrically about the symmetry axis of the two hinges 6. The clamp brackets 5 located in the center are arranged on the symmetry axis of the two hinges 6, and the distance between the clamp brackets 5 located at both ends and their corresponding external single-phase fluid high-temperature outlet 211 and external single-phase fluid low-temperature inlet 212 is between 250-300 mm. The clamp brackets 5 are glued to the plate structure protrusion 16 side of the radiator structure plate 1 and the coaxial position of the pipe. The first clamp position of the high and low temperature single-phase fluid circuit balances the plate structure protrusion 16 envelope distance of the high-temperature outlet and low-temperature inlet clamp bracket 5 to support the maximum range position of the pipe, and one is evenly distributed between the floating support 42 and the hinge 6, and is symmetrical in height up and down on the middle surface of the radiator structure plate 1. Preferably, the present application has three clamp brackets 5 arranged above and below, and one clamp bracket 5 is arranged above and below the symmetry axis of the two hinges 6 on the plate structure protrusion 16; a clamp bracket 5 is arranged at a horizontal distance of 250-300mm between the lower side of the plate structure protrusion 16 and the high-temperature outlet 211 of the external single-phase fluid, and a clamp bracket 5 is symmetrically arranged on the upper side; a clamp bracket 5 is arranged at a horizontal distance of 250-300mm between the upper side of the plate structure protrusion 16 and the low-temperature inlet 212 of the external single-phase fluid, and a clamp bracket 5 is symmetrically arranged on the lower side. The clamp bracket 5 includes a bracket 51, an insulation pad 52, and a clamp 53 from bottom to top, which is fastened by a bolt assembly 54, and the bolt assembly 54 includes a screw, a spring washer, a flat washer, and a self-locking nut. The clamp bracket 5 is designed with a lightening groove. The two-way fluid pipelines of the radiator plate external pipeline system 3 form a two-dimensional space and corner avoidance, and the pipelines are limited by the clamp bracket 5. The clamp bracket 5 is limited to consider the weak rigidity mutual adaptation of the pipeline.

[0076] The entire radiator pipeline system is integrated by pipeline welding. The pipelines and adapters inside and outside the radiator structure plate 1 are all connected by welding and brazing processes, and the leak test of the entire fluid circuit is carried out to ensure high sealing. Among them, the geometric value of the arc connection part in the S-type fluid circuit selects a metal joint that meets the minimum bending radius and adopts a machining process. At the welding interface of the welded connection parts, the notch size of the welding groove is designed to ensure the process flatness of the welding part and match the dimensional accuracy of the upper and lower skins.

[0077] Under the same radiation panel volume limitation after the radiator is deployed, the bidirectional convection single-phase fluid S-shaped layout is more efficient than the unidirectional S-shaped fluid pipeline arrangement in terms of heat dissipation design.
