Description

Technical Field

[0001] This invention relates to the field of optical remote sensing technology, specifically providing a multi-channel heat pipe heat exchange device for a space camera. Background Technology

[0002] In space cameras, to ensure the proper functioning of heat-generating equipment such as detectors and electrical boxes, heat pipes are used to transfer heat to radiant heat sinks, which then dissipate it into the cold, dark space. As the size of the space camera increases, the distance between the evaporator and condenser ends of the heat pipes becomes longer, and the heat pipe channels become more complex. Heat pipes often require multiple bends to avoid interference with structural components. This not only reduces the heat transfer capacity of the heat pipes but also makes their installation difficult. Therefore, heat pipes are typically split in two, with a heat exchanger added at a suitable location in the middle to connect the evaporator and condenser ends, allowing heat to be transferred from the evaporator to the condenser.

[0003] Traditional heat pipe heat exchangers typically employ a separate layout for the evaporator and condenser heat pipes. The cross-section of such an exchanger generally consists of three parts: an upper cover plate, a heat-conducting plate, and a lower cover plate. The evaporator and condenser heat pipes are positioned on opposite sides of the heat-conducting plate, and heat transfer primarily occurs through the plate. This type of heat exchanger has the following two drawbacks:

[0004] (1) Large volume and weight. The heat pipes at the evaporation end and the heat pipes at the condensation end are arranged on both sides of the heat-conducting plate, which makes the heat pipe heat exchange device large in volume and weight.

[0005] (2) Low heat exchange efficiency. Each evaporator heat pipe exchanges heat with a maximum of two condenser heat pipes, and each condenser heat pipe exchanges heat with a maximum of two evaporator heat pipes, resulting in low overall heat exchange efficiency of the heat pipe heat exchange device and making it difficult for heat to dissipate quickly and effectively. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a multi-channel heat pipe heat exchange device for a space camera. By arranging evaporator-end heat pipes and condenser-end heat pipes in a compact and staggered layout within the heat pipe heat exchange device, the volume and weight can be reduced, and the heat exchange efficiency can be improved. This allows for the rapid and effective dissipation of heat generated by the heat dissipation equipment, ensuring the stable and reliable operation of the space camera under various operating conditions.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not constitute a limitation thereof. Similar elements in different embodiments are referred to by associated similar element reference numerals.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] like Figures 1 to 2 As shown, in space cameras, traditional heat pipe heat exchange devices generally adopt a structure with heat pipes 1' at the evaporation end and heat pipes 2' at the condensation end arranged separately. The cross-section of the heat pipe heat exchange device generally consists of three parts: an upper cover plate 3', a heat-conducting plate 4', and a lower cover plate 5'. The heat pipes 1' at the evaporation end and 2' at the condensation end are arranged on both sides of the heat-conducting plate 4', and heat is mainly transferred through the heat-conducting plate 4'.

[0048] The above-mentioned heat pipe heat exchange device has the following two disadvantages:

[0049] (1) The evaporation end heat pipe 1' and the condensation end heat pipe 2' are arranged on both sides of the heat-conducting plate, which makes the heat pipe heat exchange device larger in size and weight.

[0050] (2) Each evaporating end heat pipe 1' exchanges heat with a maximum of two condensing end heat pipes 2', and each condensing end heat pipe 2' exchanges heat with a maximum of two evaporating end heat pipes 1', resulting in low overall heat exchange efficiency of the heat pipe heat exchange device and difficulty in quickly and effectively dissipating heat.

[0051] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0052] like Figures 3 to 6 As shown, an embodiment of the present invention provides a multi-channel heat pipe heat exchange device for a space camera, specifically including a flexible heat-conducting tape 1, a heat-conducting plate, and a heat pipe layer. The flexible heat-conducting tape 1 has a C-shaped structure including a first end and a second end. The heat-conducting plate includes an upper heat-conducting plate 2, a lower heat-conducting plate 3, and an intermediate heat-conducting plate arranged in a horizontal direction. The upper heat-conducting plate 2 is connected to the first end of the flexible heat-conducting tape 1, and the lower heat-conducting plate 3 is connected to the second end of the flexible heat-conducting tape 1, so that the upper heat-conducting plate 2 and the lower heat-conducting plate 3 can directly exchange heat through the flexible heat-conducting tape 1, thereby enabling the upper heat pipe layer to exchange heat with the lower heat pipe layer, thus improving the heat exchange efficiency.

[0053] like Figures 3 to 4As shown, at least one intermediate heat-conducting plate is sequentially stacked between the upper heat-conducting plate 2 and the lower heat-conducting plate 3, such that the upper heat-conducting plate 2 and the lower intermediate heat-conducting plate, adjacent intermediate heat-conducting plates, and the intermediate heat-conducting plate and the lower lower heat-conducting plate 3 are in close contact with each other, forming a receiving layer. The heat pipe layer includes multiple evaporating end heat pipes 5 or multiple condensing end heat pipes 6. At least one heat pipe layer including evaporating end heat pipes 5 and at least one heat pipe layer including condensing end heat pipes 6 are respectively disposed in the receiving layer, so that the heat pipe layer can exchange heat with the upper and lower heat-conducting plates, thereby realizing heat exchange between the evaporating end heat pipes 5 and the condensing end heat pipes 6 through the heat-conducting plates.

[0054] like Figures 3 to 4 As shown, the heat pipe layers in adjacent containment layers are of different types, used to achieve heat exchange between the heat pipe layer including the evaporator heat pipe 5 and the heat pipe layer including the condenser heat pipe 6. The evaporator heat pipe 5 and the condenser heat pipe 6 in adjacent heat pipe layers are staggered, so that each evaporator heat pipe 5 can exchange heat with up to four condenser heat pipes 6 on the upper left, lower left, upper right and lower right sides respectively; each condenser heat pipe 6 can exchange heat with up to four evaporator heat pipes 5 on the upper left, lower left, upper right and lower right sides respectively, thereby improving heat exchange efficiency.

[0055] Therefore, by setting up a compact and staggered layout of evaporator heat pipe 5 and condenser heat pipe 6, the volume and weight of the heat pipe heat exchange device can be reduced, the heat exchange efficiency can be improved, and the heat generated by the heat dissipation equipment can be quickly and effectively dissipated, ensuring that the space camera operates stably and reliably under various operating conditions.

[0056] The flexible heat-conducting tape 1 has a first end at the top of the C-shaped opening side and a second end at the bottom of the C-shaped opening side. Preferably, the upper heat-conducting plate 2 is welded to the first end of the flexible heat-conducting tape 1, and the lower heat-conducting plate 3 is welded to the second end of the flexible heat-conducting tape 1.

[0057] like Figures 7 to 8 As shown, the bottom surface of the upper heat-conducting plate 2 has multiple parallel first heat pipe channels 21 for accommodating the evaporating end heat pipe 5 or the condensing end heat pipe 6. The side surface of the upper heat-conducting plate 2 has multiple first mounting ears 22, and the first mounting ears 22 have first light holes 23 for connecting with other heat-conducting plates.

[0058] like Figures 9 to 10 As shown, the top surface of the lower heat-conducting plate 3 has multiple parallel-arranged second heat pipe channels 31 for accommodating the evaporator heat pipe 5 or the condenser heat pipe 6. The side surface of the lower heat-conducting plate 3 has multiple second mounting ears 32, and the second mounting ears 32 have second light holes 33 for connecting with other heat-conducting plates.

[0059] like Figures 11 to 14As shown, in some possible embodiments, the intermediate heat-conducting plate is an M-shaped heat-conducting plate 41. The top surface of the M-shaped heat-conducting plate 41 has... m ( m =1,2,3...) parallel third heat pipe channels 411, the bottom surface of the M-shaped heat conduction plate 41 is provided with m +1( m (1, 2, 3...) parallel fourth heat pipe channels 412 are used to accommodate the evaporator heat pipe 5 or the condenser heat pipe 6. The third heat pipe channel 411 has a semi-circular cross-section, with the center of the cross-section located on the top surface of the M-shaped heat-conducting plate 41, allowing it to precisely accommodate the bottom half of the evaporator heat pipe 5 or the condenser heat pipe 6. The fourth heat pipe channel 412 has a semi-circular cross-section, with the center of the cross-section located on the bottom surface of the M-shaped heat-conducting plate 41, allowing it to precisely accommodate the top half of the evaporator heat pipe 5 or the condenser heat pipe 6.

[0060] like Figure 3 , Figures 15 to 17 As shown, in some possible embodiments, the intermediate heat-conducting plate is a W-shaped heat-conducting plate 42. The top surface of the W-shaped heat-conducting plate 42 has an opening... n ( n =2, 3, 4...) parallel fifth heat pipe channels 421, the bottom surface of the W-shaped heat conduction plate 42 is provided with n -1( n (2, 3, 4...) parallel sixth heat pipe channels 422 are used to accommodate the evaporator-end heat pipe 5 or the condenser-end heat pipe 6. The fifth heat pipe channel 421 has a semi-circular cross-section, with its center located on the top surface of the W-shaped heat-conducting plate 42, allowing it to precisely accommodate the bottom half of the evaporator-end heat pipe 5 or the condenser-end heat pipe 6. The sixth heat pipe channel 422 has a semi-circular cross-section, with its center located on the bottom surface of the W-shaped heat-conducting plate 42, allowing it to precisely accommodate the top half of the evaporator-end heat pipe 5 or the condenser-end heat pipe 6.

[0061] like Figure 4 , Figures 7 to 17 As shown, in some possible embodiments, the upper part of the M-shaped heat-conducting plate 41 may be the upper heat-conducting plate 2, and the number and position of the third heat pipe channel 411 correspond one-to-one with the first heat pipe channel 21, so that the third heat pipe channel 411 can be surrounded by the first heat pipe channel 21 to form a complete channel for accommodating the heat pipe layer.

[0062] In some possible embodiments, the lower part of the M-shaped heat-conducting plate 41 may be an M-shaped heat-conducting plate 41, with the number and position of the fourth heat pipe channel 412 of the upper M-shaped heat-conducting plate 41 corresponding to the third heat pipe channel 411 of the lower M-shaped heat-conducting plate 41, so that the upper fourth heat pipe channel 412 and the lower third heat pipe channel 411 can surround and form a complete channel for accommodating the heat pipe layer. The lower part of the M-shaped heat-conducting plate 41 may also be a W-shaped heat-conducting plate 42, with the number and position of the fourth heat pipe channel 412 and the fifth heat pipe channel 421 corresponding to each other, so that the fourth heat pipe channel 412 and the fifth heat pipe channel 421 can surround and form a complete channel for accommodating the heat pipe layer.

[0063] In some possible embodiments, the lower part of the W-shaped heat-conducting plate 42 may be a W-shaped heat-conducting plate 42, with the sixth heat pipe channel 422 of the upper W-shaped heat-conducting plate 42 corresponding one-to-one with the fifth heat pipe channel 421 of the lower W-shaped heat-conducting plate 42 in terms of number and position. This allows the upper sixth heat pipe channel 422 to form a complete channel with the lower fifth heat pipe channel 421, used to accommodate the heat pipe layer. Alternatively, the lower part of the W-shaped heat-conducting plate 42 may be a lower heat-conducting plate 3, with the sixth heat pipe channel 422 corresponding one-to-one with the second heat pipe channel 31 in terms of number and position. This allows the sixth heat pipe channel 422 to form a complete channel with the second heat pipe channel 31, used to accommodate the heat pipe layer.

[0064] In other words, by stacking intermediate heat-conducting plates with matching number of channels in sequence, the evaporation end heat pipes 5 and condensation end heat pipes 6 of adjacent heat pipe layers can be staggered. Each evaporation end heat pipe 5 can exchange heat with up to four condensation end heat pipes 6, and each condensation end heat pipe 6 can exchange heat with up to four evaporation end heat pipes 5. The heat transfer is more concentrated and efficient, and the large amount of heat generated inside the space camera can be dissipated in a timely manner.

[0065] Among them, M-shaped heat-conducting plates 41 and W-shaped heat-conducting plates 42 are stacked in sequence to form a compact layout structure in which the number of heat pipes in the top and bottom heat pipe layers of the multi-channel heat pipe heat exchange device of the space camera is small, while the number of heat pipes in the middle heat pipe layer is large. This can reduce the volume and weight and adapt to the limited installation space of the space camera.

[0066] like Figures 11 to 17 As shown, the side of the M-shaped heat-conducting plate 41 is provided with multiple third mounting ears 413. The top of the third mounting ears 413 is provided with a first screw hole 414, and the bottom of the third mounting ears 413 is provided with a third through hole 415. The side of the W-shaped heat-conducting plate 42 is provided with multiple fourth mounting ears 423. The top of the fourth mounting ears 423 is provided with a first mounting hole 424, and the bottom of the fourth mounting ears 423 is provided with a second mounting hole 425.

[0067] Specifically, for the M-shaped heat-conducting plate 41, when the upper heat-conducting plate 2 is above the M-shaped heat-conducting plate 41, the first screw hole 414 is used to connect with the first optical hole 23, thereby connecting the M-shaped heat-conducting plate 41 to the upper heat-conducting plate 2. When the lower part of the M-shaped heat-conducting plate 41 is another M-shaped heat-conducting plate 41, the third optical hole 415 of the upper M-shaped heat-conducting plate 41 is used to connect with the first screw hole 414 of the lower M-shaped heat-conducting plate 41, thereby connecting the adjacent M-shaped heat-conducting plate 41. When the lower part of the M-shaped heat-conducting plate 41 is a W-shaped heat-conducting plate 42, the third optical hole 415 is used to connect with the first mounting hole 424, thereby connecting the M-shaped heat-conducting plate 41 to the W-shaped heat-conducting plate 42.

[0068] For the W-shaped heat-conducting plate 42, when the upper W-shaped heat-conducting plate 42 is below another W-shaped heat-conducting plate 42, the second mounting hole 425 of the upper W-shaped heat-conducting plate 42 is used to connect with the first mounting hole 424 of the lower W-shaped heat-conducting plate 42, thereby connecting the adjacent W-shaped heat-conducting plates 42. When the lower W-shaped heat-conducting plate 42 is below the lower heat-conducting plate 3, the second mounting hole 425 is used to connect with the second aperture 33, thereby connecting the W-shaped heat-conducting plate 42 to the lower heat-conducting plate 3.

[0069] like Figures 15 to 17 As shown, the side of the W-shaped heat-conducting plate 42 is provided with multiple assembly lugs 426, and the assembly lugs 426 are provided with assembly light holes 427. The assembly light holes 427 are used to connect the multi-channel heat pipe heat exchange device of the space camera to the space camera, thereby dissipating heat from the space camera.

[0070] In some possible embodiments, the flexible conductive tape 1 is made of graphite, which gives it good thermal conductivity. The flexible conductive tape 1 includes a multi-layer graphite structure, which further enhances its thermal conductivity.

[0071] In some possible embodiments, aluminum alloy is used as the material for the upper heat-conducting plate 2, the lower heat-conducting plate 3, and the middle heat-conducting plate because of the high thermal conductivity of aluminum alloy.

[0072] Example:

[0073] A multi-channel heat pipe heat exchange device for a space camera includes a flexible heat-conducting tape 1, a heat-conducting plate, and heat pipe layers. The flexible heat-conducting tape 1 has a C-shaped structure including a first end and a second end, and is made of graphite with a multi-layer graphite structure. The heat-conducting plate is made of aluminum alloy and includes an upper heat-conducting plate 2, a lower heat-conducting plate 3, two M-shaped heat-conducting plates 41, and a W-shaped heat-conducting plate 42 arranged horizontally. The upper heat-conducting plate 2 is welded to the first end of the flexible heat-conducting tape 1, and the lower heat-conducting plate 3 is welded to the second end of the flexible heat-conducting tape 1. The two M-shaped heat-conducting plates 41 and the W-shaped heat-conducting plate 42 are stacked between the upper heat-conducting plate 2 and the lower heat-conducting plate 3, so that four containment layers are formed between adjacent heat-conducting plates from top to bottom. Each heat pipe layer includes an evaporating end heat pipe 5 or a condensing end heat pipe 6. Specifically, the first and third containment layers from top to bottom are evaporating end heat pipes 5, and the second and fourth containment layers are condensing end heat pipes 6.

[0074] The upper heat-conducting plate 2 has four parallel first heat pipe channels 21 on its bottom surface, and the lower heat-conducting plate 3 has five parallel second heat pipe channels 31 on its top surface. The first and second intermediate heat-conducting plates below the upper heat-conducting plate 2 are both M-shaped heat-conducting plates 41. The top surface of the first M-shaped heat-conducting plate 41 has four parallel third heat pipe channels 411, and the bottom surface has five parallel fourth heat pipe channels 412. The top surface of the second M-shaped heat-conducting plate 41 has five parallel third heat pipe channels 411, and the bottom surface has six parallel fourth heat pipe channels 412. The third intermediate heat-conducting plate below the upper heat-conducting plate 2 is a W-shaped heat-conducting plate 42. The top surface of the W-shaped heat-conducting plate 42 has six parallel fifth heat pipe channels 421, and the bottom surface has five parallel sixth heat pipe channels 422. This allows for the staggered arrangement of evaporator heat pipe 5 and condenser heat pipe 6 in adjacent heat pipe layers.

[0075] Due to the staggered arrangement of evaporator-end heat pipes 5 and condenser-end heat pipes 6 in adjacent heat pipe layers, each evaporator-end heat pipe 5 can exchange heat with up to four condenser-end heat pipes 6, and each condenser-end heat pipe 6 can exchange heat with up to four evaporator-end heat pipes 5. This results in more concentrated and efficient heat transfer, effectively dissipating the large amount of heat generated inside the space camera. Furthermore, the sequential stacking of M-shaped heat-conducting plates 41 and W-shaped heat-conducting plates 42 creates a compact layout with fewer heat pipes in the top and bottom heat pipe layers and a larger number of heat pipes in the middle layer. This reduces the size and weight of the multi-channel heat pipe heat exchange device for the space camera, making it more suitable for the limited installation space available for the space camera.
