Description

Technical Field

[0001] This utility model relates to the field of cooling wall panel structures, and more particularly to active cooling wall panel structures for space shuttles. Background Technology

[0002] The Space Shuttle is a reusable manned spacecraft that combines the characteristics of an airplane and a spacecraft, traveling between the Earth's surface and low Earth orbit. The active cooling panel structure used in the Space Shuttle's thermal protection system is a structure that actively cools the panels to cope with extreme thermal environments. It relies on the circulation of coolant for cooling. The coolant is typically a fluid with good thermal conductivity, such as liquid hydrogen, liquid oxygen, or other special cooling media. During Space Shuttle flight, especially during atmospheric reentry, the panels absorb a large amount of heat. The coolant flows within the cooling channels, carrying away the heat from the panels through convection heat transfer. After absorbing heat from the panels, the coolant's temperature rises, and it then flows out of the panels through coolant outlets into other parts of the cooling system, such as radiators, dissipating the heat into space. This allows the coolant to be recycled and reused to continue cooling the panels.

[0003] Most existing cooling wall panel structures are unidirectionally fixed. Impurities, corrosion products, or coking generated at high temperatures in the coolant may block the cooling channels. If the structure is not easy to disassemble, this blockage will reduce or make the coolant flow uneven, leading to local overheating, reducing the service life of the wall panel, and in severe cases, causing the wall panel structure to fail.

[0004] Therefore, since most of the existing cooling wall panel structures adopt unidirectional fixing, impurities in the coolant may block the cooling channels. If the structure is not easy to disassemble, this blockage will reduce the service life and performance of the wall panel. An active cooling wall panel structure for space shuttles can be designed, which adopts a cooling wall panel structure that is easy to disassemble and assemble, thereby improving the service life and performance. Utility Model Content

A fixing ring is fitted on the outside of the side of the branch pipe away from the main pipe. An annular snap-fit ​​plate is installed on the edge of the fixing ring away from the main pipe. The annular snap-fit ​​plate drives the fixing ring to be positioned and snapped with the top plate and the bottom plate along the annular snap-fit ​​groove.

[0007] Preferably, the bottom plate and the top plate are fitted together, and the connection between the bottom plate and the top plate is reinforced by U-shaped fasteners. Then, the inlet pipe and the outlet pipe are positioned and assembled with the bottom plate and the top plate. Then, the coolant enters the pipe formed between the bottom plate and the top plate from the inlet pipe. The coolant flows in the cooling channel and carries away the heat of the wall panel through convection heat transfer. After a period of time, it is discharged from the outlet pipe.

Then, the inlet pipe and outlet pipe are positioned and assembled with the bottom plate and top plate. The coolant then enters the pipe formed between the bottom plate and top plate through the inlet pipe.

Impurities, scale and other blockages in the cooling channel can also be easily cleaned and unblocked, which greatly improves the efficiency and feasibility of maintenance and repair.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4This utility model provides an embodiment of an active cooling panel structure for a space shuttle, comprising a top plate 1, a bottom plate 2, U-shaped fasteners 3, an inlet pipe 4, and an outlet pipe 5. The bottom plate 2 is symmetrically positioned below the top plate 1 for positioning and connection with it. Multiple sets of U-shaped fasteners 3 are symmetrically arranged laterally on both sides of the connection between the bottom plate 2 and the top plate 1 for reinforcement. One end of the top plate 1 has an inlet pipe 4 for introducing coolant, and the other end of the top plate 1 away from the inlet pipe 4 has an outlet pipe 5 for discharging coolant. The outlet pipe 5 is arranged in the same manner as the inlet pipe 4. Three sets of first arc-shaped grooves 103 are longitudinally spaced below the top plate 1. First semi-annular snap-fit ​​grooves 102 are located at both ends of the first arc-shaped grooves 103 on the top plate 1. Multiple sets of insertion posts 104 are installed at the lower end of the top plate 1. The bottom plate 2 is connected to the insertion posts 104 above it. A corresponding insertion hole 204 is provided. A second arc groove 203 is provided above the bottom plate 2, corresponding to the first arc groove 103. A second semi-annular snap-fit ​​groove 202 is provided on the bottom plate 2 at both ends of the second arc groove 203. The second semi-annular snap-fit ​​groove 202 on the bottom plate 2 and the first semi-annular snap-fit ​​groove 102 on the top plate 1 form an annular snap-fit ​​groove. A main pipe 404 is installed at one end of the inlet pipe 4. Three sets of branch pipes 405 are installed longitudinally at intervals on the side of the main pipe 404 away from the inlet pipe 4. A fixing ring sleeve 406 is sleeved on the outside of the side of the branch pipe 405 away from the main pipe 404. An annular snap-fit ​​plate 407 is installed on the edge of the fixing ring sleeve 406 away from the main pipe 404. The annular snap-fit ​​plate 407 drives the fixing ring sleeve 406 to be positioned and snapped with the top plate 1 and the bottom plate 2 along the annular snap-fit ​​groove.

[0022] Please see Figures 2-3 In this embodiment, the top plate 1 has first connecting holes 101 on both sides corresponding to the U-shaped fasteners 3. The first connecting holes 101 facilitate the passage of the U-shaped fasteners 3 for reinforcement. The plug-in post 104 and the first arc-shaped groove 103 are staggered. The first arc-shaped groove 103 below the top plate 1 and the second arc-shaped groove 203 above the bottom plate 2 form a pipe for coolant to flow through. The bottom plate 2 has second connecting holes 201 on both sides corresponding to the U-shaped fasteners 3. The second connecting holes 201 facilitate the passage of the U-shaped fasteners 3 for reinforcement. The plug-in post 104 drives the top plate 1 to be positioned and connected to the bottom plate 2 through the plug-in hole 204, so that the top plate 1 and the bottom plate 2 are relatively fitted together. At the same time, the plug-in post 104 drives the top plate 1 to be positioned and connected to the bottom plate 2 through the plug-in hole 204.

[0023] Please see Figure 4In this embodiment, a threaded groove 401 is provided on the inner wall of the inlet pipe 4. The coolant inlet pipe is threadedly connected to the inlet pipe 4 along the threaded groove 401. A telescopic valve 402 is provided at the connection between the inlet pipe 4 and the main pipe 404. An electromagnetic control valve 403 (model AD-8A-N-G1) is installed on the outer side of the telescopic valve 402. Under the control of the electromagnetic control valve 403, the telescopic valve 402 is opened, and the coolant flows from the main pipe 404 into the branch pipe 405 along the pipeline formed between the bottom plate 2 and the top plate 1.

[0024] During operation, the top plate 1 and bottom plate 2 are first fitted together. Simultaneously, the insertion post 104 drives the top plate 1 to be positioned and connected to the bottom plate 2 through the insertion hole 204. Next, the U-shaped fastener 3 is picked up and its two ends are inserted into the first connection hole 101 and the second connection hole 201 respectively, reinforcing the connection between the top plate 1 and bottom plate 2. This forms a coolant flow channel through the first arc-shaped groove 103 below the top plate 1 and the second arc-shaped groove 203 above the bottom plate 2. Then, the branch pipe 405 is picked up, and the annular snap-fit ​​plate 407 drives the fixing ring 406 to be positioned and snapped into the top plate 1 and bottom plate 2 along the first semi-annular snap-fit ​​groove 102 and the second semi-annular snap-fit ​​groove 202, thus completing the guide... After assembling the inlet pipe 4, repeat the above operation to complete the assembly of the outlet pipe 5. Finally, connect the coolant inlet pipe to the inlet pipe 4 along the threaded groove 401, and connect the outlet pipe to the outlet pipe 5 along the threaded groove 401. After assembly, it can be used. Under the control of the electromagnetic control valve 403, the telescopic valve 402 is opened, and the coolant flows from the main pipe 404 into the branch pipe 405 along the pipe formed between the bottom plate 2 and the top plate 1. The heat of the wall panel is carried away by convection heat exchange. After a period of time, it is discharged from the outlet pipe 5. After a period of use, the entire structure can be disassembled and its interior cleaned to avoid blockages.

[0025] Through the above steps, the base plate 2 and top plate 1 are fitted together, and the connection between the base plate 2 and top plate 1 is reinforced by the U-shaped fastener 3. Then, the inlet pipe 4 and outlet pipe 5 are positioned and assembled with the base plate 2 and top plate 1. The coolant then enters the pipe formed between the base plate 2 and top plate 1 through the inlet pipe 4. The coolant flows in the cooling channel and carries away the heat of the wall panel through convection heat transfer. After a period of time, it is discharged from the outlet pipe 5. By adopting a cooling wall panel structure that is easy to disassemble and assemble, when the cooling channel inside the cooling wall panel is blocked, or the wall panel structure is damaged or has other faults, the detachable design allows maintenance personnel to remove the wall panel from the space shuttle for more in-depth and comprehensive inspection and maintenance. Impurities, scale and other blockages in the cooling channel can also be easily cleaned and unblocked, which greatly improves the efficiency and feasibility of maintenance and repair. This solves the problem that most existing cooling wall panel structures use unidirectional fixation, and impurities in the coolant may block the cooling channel. If the cooling structure is not easy to disassemble, this blockage will reduce the service life and performance of the wall panel.
