[0031] Embodiment 1

[0032] Referring to Figure 1 to Figure 5, this embodiment provides an adjustable radiator, including a plurality of heat dissipation assemblies 100, a plurality of soft connection assemblies 200, and a plurality of locking assemblies 300; the plurality of soft connection assemblies 200 are connected between the adjacent heat dissipation assemblies 100, so that the included angle between the adjacent heat dissipation assemblies 100 is adjustable, and the soft connection assembly 200 allows the hot fluids in the heat dissipation assembly 100 to be in fluid communication with each other; and the locking assembly 300 is connected to the soft connection assembly 200, and the locking assembly 300 is used for fixing the soft connection assembly 200, so that the adjacent heat dissipation assembly 100 having their included angle adjusted remains fixed.

[0033] In this embodiment, the plurality of heat dissipation assemblies 100 may be flexibly connected by the soft connection assembly 200, and the soft connection assembly 200 may allow a heat fluid to circulate between the heat dissipation assemblies 100, such that the hot fluid can flow into the next heat dissipation assembly 100 from the preceding one. In this way, the radiator including multiple heat dissipation assemblies 100 constitutes an integrated structure that permits the circulation of hot fluid. Meanwhile, due to the flexible connection, the angle between adjacent heat dissipation assemblies 100 can be freely adjusted, thereby allowing the overall windward of the radiator to be changed according to actual external conditions and achieving structural adjustability for environmental adaptation. After adjustment, the soft connection assemblies 200 are fixed by the locking assembly 300, so that adjacent heat dissipation assemblies 100 maintain at a fixed angle. Therefore, compared with conventional radiators, the present embodiment realizes the function of structural adjustability to adapt to the environment, satisfies the requirement for flexibility and maneuverability of the radiator, and improves both usage flexibility and structural compactness.

[0034] It should be noted that the included angles of the adjacent heat dissipation assemblies 100 may be the same or different, and may be adjusted more finely according to actual environmental conditions, as long as the windward area of all the heat dissipation assemblies 100 can meet the use requirements. This enables flexible use. After adjustment, the adjusted heat dissipation assemblies 100 are supported and fixed by means of a support member (not shown in the figures), which may be an I-beam bracket, or a modular profile rack or directly embedded into the ground.

[0035] As an optional implementation, the soft connection assembly 200 includes a joint pipe 210 and a hose 220, both ends of the heat dissipation assembly 100 are connected to respective joint pipes 210, and the hose 220 is connected between the adjacent joint pipes 210.

[0036] In this embodiment, the joint pipes 210 may be welded to the outlets of the two ends of the heat dissipation assembly 100, the adjacent joint pipes 210 are connected through the hose 220, and the hose 220 can allow the adjacent heat dissipation assemblies 100 to swing freely, so that the included angle of the adjacent heat dissipation assemblies 100 can be conveniently adjusted.

[0037] It should be noted that the hose 220 may be fixed to the joint pipe 210 by conventional means such as ferrule fittings or adhesive bonding, facilitating assembly while ensuring a stable and reliable structure. The hose 220 is made of non-metallic materials such as polytetrafluoroethylene or rubber, which are sealable and deformable. The hose 220 may be a rubber hose having a slightly smaller diameter than that of the joint pipe 210, so that when it is sleeved onto the joint pipe 210, it makes tight contact therewith to ensure that no fluid leakage occurs.

[0038] As an optional implementation, the locking assembly 300 includes a first locking piece 310, a second locking piece 320 and a fixing portion 330. The first locking piece 310 is connected to the joint pipe 210, one end of the second locking piece 320 is connected to a neighboring joint pipe 210, and the other end of the second locking piece 320 is slidably connected to the first locking piece 310. The fixing portion 330 is configured to fix the second locking piece 320 to the first locking piece 310.

[0039] In this embodiment, a sliding groove may be formed in the first locking piece 310, and the second locking piece 320 is slidably embedded in the sliding groove, so that the overall length of the first locking piece 310 and the second locking piece 320 can be changed by means of sliding and telescopic adjustment, thereby accommodating the change in spacing between the two joint pipes 210 after adjustment of the angle between adjacent heat dissipation assemblies 100. This provides strong versatility. The second locking piece 320 is fixed to the first locking piece 310 by the fixing portion 330 so as to maintain a fixed combined length of the first locking piece 310 and the second locking piece 320, thereby preventing relative movement between the adjacent joint pipes 210 and achieving the effect of keeping the adjacent heat dissipation assembly 100 fixed.

[0040] It should be noted that the first locking piece 310 and the second locking piece 320 herein may be metallic sheet-like structures. The first locking piece 310 and the second locking piece 320 may be welded or hinged to the corresponding joint pipe 210. In the case of a welded structure, the angle between adjacent heat dissipation assemblies 100 is first adjusted, after which the first locking piece 310 and the second locking piece 320 are slid and extended or retracted to match the spacing between the two joint pipes 210 following adjustment. The two pieces are then fixed by the fixing portion 330 to maintain the overall length, and the respective ends of the first and second locking pieces 310 are welded to the corresponding joint pipes 210, thereby forming a fixed structure suitable for long-term use. In the case of a hinged structure, the first locking piece 310 and the second locking piece 320 are pre-hinged to the corresponding joint pipes 210. When the angle between adjacent heat dissipation assemblies 100 is adjusted, the first and second locking pieces 310 and 320 can automatically expand or contract accordingly, thereby providing a self-adaptive function. After adjustment, the pieces are fixed in place via the fixing portion 330. During subsequent use, the fixing portion 330 can be released to allow for re-adjustment, making the structure reusable and highly versatile. To prevent rotation in the hinged structure, the entire radiator may be supported and constrained by support members. The fixing portion 330 can adopt a knob structure, bolt-and-nut fastening, hot-melt adhesive, or other fixation means, provided that the structure allows for locking and unlocking as needed, no limitation is placed here. In the case of bolt fixation, corresponding elongated slots are formed on the first and second locking pieces 310 to allow bolts to pass through for securing.

[0041] In an optional implementation, the included angle ranges from 0° to 180°.

[0042] In this embodiment, the plurality of heat dissipation assemblies 100 can be combined in various configurations. The plurality of heat dissipation assemblies 100 can be connected end to end in a linear arrangement, as shown in Figure 4, where the included angle between the heat dissipation assemblies 100 is 180°. Alternatively, the heat dissipation assemblies 100 may be connected in a vertically stacked arrangement, as shown in Figure 5, where the included angle between the heat dissipation assemblies 100 is 0°. When the included angle between adjacent heat dissipation assemblies 100 is between 0° and 180°, the arrangement is as shown in Figure 1. The arrangement is flexible, and can meet various use requirements.

[0043] In an optional implementation, the heat dissipation assembly 100 includes a first flow channel plate 110 and a second flow channel plate 130, a first side flow channel 120 is provided in the first flow channel plate 110, two ends of the first side flow channel 120 are both connected to the joint pipe 210, and the first side flow channel 120 is configured to receive a hot fluid; the second flow channel plate 130 is connected to the top or the bottom of the first flow channel plate 110, the surface of the second flow channel plate 130 close to the first flow channel plate 110 is provided with a plurality of second side flow channels 131, the second side flow channel 131 is oriented perpendicular to the direction of the first side flow channel 120, and the second side flow channel 131 is configured to receive a cold fluid.

[0044] In this embodiment, when the angle of end-to-end connected heat dissipation assemblies 100 is properly adjusted, the hot fluid flows into the joint pipe 210 at one end. The hot fluid then enters the first side flow channel 120 and flows out through the joint pipe at other end. The cold fluid (generally air) can cool the heat fluid directly through the exposed second side flow channel 131, thereby achieving heat exchange. Meanwhile, the second side flow channel 131 is orientated perpendicular to the direction of the first side flow channel 120, which improves the heat dissipation efficiency.

[0045] It should be noted that the first flow channel plate 110 and the second flow channel plate 130 may be integrally formed by welding methods such as vacuum diffusion welding, brazing, or fusion welding, providing high connection strength. To further enhance heat dissipation efficiency, multiple heat dissipation assemblies 100 can be stacked and welded together in a sequential manner, thereby forming a multichannel heat dissipation assembly 100 (as shown in Figure 3), which meets a wider range of usage requirements.

[0046] As an optional implementation, the first flow channel plate 110 includes an upper flow channel plate 111 and a lower flow channel plate 112, and the bottom of the upper flow channel plate 111 is provided with a first arc-shaped groove; the top of the lower flow channel plate 112 is provided with a second arc-shaped groove, and the lower flow channel plate 112 is connected to the bottom of the upper flow channel plate 111, so that the second arc-shaped groove and the first arc-shaped groove together define a first side flow channel 120.

[0047] In this embodiment, the first flow channel plate 110 is divided into the upper flow channel plate 111 and the lower flow channel plate 112. After the first arc-shaped groove and the second arc-shaped groove are processed separately, the upper flow channel plate 111 and the lower flow channel plate 112 are integrally formed by welding methods such as vacuum diffusion welding, brazing, or fusion welding. This results in the second arc-shaped groove and the first arc-shaped groove define the first side flow channel 120, thus forming an integrally formed first flow channel plate 110, which reduces the manufacturing complexity.

[0048] It should be noted that the upper flow channel plate 111, the lower flow channel plate 112, and the second flow channel plate 130 can be made of metal sheets with the same or different dimensions in length and width, and the same or different thicknesses. Small flow channels are processed on all three flow channel plates using processes such as chemical etching. The first side flow channel 120 and the second side flow channel 131 may be different is shape. The materials for the heat dissipation assemblies may include metals such as stainless steel, carbon steel, titanium alloys, or non-metallic materials such as ceramics. The connections between the flow channel plates and the joint pipes 210, as well as between the joint pipes 210 and the locking pieces, may use various welding methods such as argon arc welding, brazing, or ion welding. According to the design, large numbers of flow channels can be processed on stainless steel mirror plates using methods like chemical etching or mechanical cutting to obtain the corresponding flow channel plates. The flow channel plates are then stacked in sequence and connected by diffusion welding to form the heat dissipation assembly 100. Joint pipes 210 of suitable sizes are welded to the first side flow channel 120 on both sides of the heat dissipation assembly 100. Based on the flow rate in the operating environment, the flow area is calculated to match the heat dissipation power. The adjacent heat dissipation assemblies 100, after having the angle therebetween adjusted, are fixed in place for heat dissipation.

[0049] As an optional implementation, the first side flow channel 120 and the second side flow channel 131 have a linear, zigzag, or S-shaped configuration in their longitudinal direction. The linear configuration is easy to process, while the zigzag or S-shaped configuration can improve the fluid flow rate, thereby enhancing the heat dissipation performance.

[0050] In an optional implementation, the first side flow channel 120 is circular, oval, or polygonal (for example, rectangular, square, or pentagonal) in cross section, and the second side flow channel 131 is semicircular or polygonal in cross section. Other suitable cross-sectional shapes may also be used, all of which can meet usage requirements.

[0051] As an optional implementation, the first flow channel plate 110 and the second flow channel plate 130 in their longitudinal direction are rectangular, arc-shaped or wavy, as long as the requirement of no gap remaining between adjacent flow channel plates after stacking is met.

[0052] It should be noted that the thickness of each flow channel plate is approximately 2mm, the cross-sectional dimension of the side flow channel ranges from 1mm to 10mm, the lateral offset distance between adjacent side flow channels ranges from 0.5mm to 10mm. The surface flow heat transfer characteristic in the side flow channels may be tuned by changing the surface roughness, adding attachments, adding a vortex generator or the like.

[0053] In summary, the radiator of the embodiments features an adjustable structure that enables tuning of its included angle to adapt the windward area to varying external environments. Moreover, by employing a microchannel design, the radiator improves the convective heat transfer performance of the working fluid, offering strong applicability across a wide range of thermal management scenarios and demonstrating significant potential for market application.

[0054] Embodiment 2

[0055] Referring to Figure 1 to Figure 5, this embodiment provides a method for using an adjustable radiator, including the following steps: unfold the adjustable radiator having a plurality of heat dissipation assemblies 100 at a preset included angle, and place it in an atmospheric environment; obtain an adjustment angle 0, where 0 is expressed as: „ ■ Q' 0=arcsin — where 0 is an included angle between the heat dissipation assembly 100 and a vertical plane, N is the number of the heat dissipation assemblies 100, Q is an initial air flow rate, and Q' is the air flow rate measured after a preset period of time; compare the measured air flow rate Q' with the initial air flow rate Q; if Q’>Q, adjusting the included angle between adjacent heat dissipation assemblies 100 to increase the adjustment angle 9 until a preset air flow rate (i.e., the most economical air flow rate) is reached; and if Q'<Q, adjust the included angle between adjacent heat dissipation assemblies to decrease the adjustment angle 9 until the preset air flow rate is reached.

[0056] In this embodiment, the N heat dissipation assemblies 100 are fabricated and are connected end to end via a corresponding number of soft connection assemblies 200 to form an integrated structure. For each heat dissipation assembly 100, the total cross-sectional area of the second side flow channels 131, i.e., the flow area of the cold fluid, is denoted as S2, and the total cross-sectional area of the first side flow channels 120, i.e., the flow area of the hot fluid, is denoted as S1. When the heat dissipation assemblies 100 are stacked as shown in Figure 5 (with each second side flow channel 131 facing the flow direction of the cold fluid), the hot fluid flows through the inner pipes, and the cold fluid flows in a direction parallel to the locking pieces for heat dissipation, resulting in a flow area of Si for the hot fluid and a flow area of S2 for the cold fluid. When the bending angle of the radiator needs to be adjusted, the included angle 9 between each heat dissipation assembly 109 and the vertical plane is adjusted, and all fastening portions 330 are then tightened to complete the adjustment. In this case, the hot fluid still flows through the inner pipes, while the cold fluid flows in a direction perpendicular to the locking pieces, the flow area for the hot fluid remains Si, while the flow area for the cold fluid becomes NxS2xsin9, as shown in Figure 1. In the extreme case where all heat dissipation assemblies 100 are arranged in a straight horizontal line, as shown in Figure 4, the flow area for the cold fluid becomes NXS2.

[0057] During use, the initial state of the radiator including the N heat dissipation assemblies 100 is fully stacked and placed in an atmospheric environment, and the cold fluid is air. In this case, the air flow area is S2, the air flow rate is Q, and there is 9o such that NxS2xsin9o=S2. Oo is the critical included angle. When 9<9o, the air flow area of the radiator is less than the air flow area in the fully stacked state, which leads to an increase in air flow rate. When 9>9o, the air flow area of the radiator is larger than the air flow area in the fully stacked state, which leads to a decrease in air flow rate.

[0058] During actual operation, if the air flow rate changes to Q' due to the climate reason, the included angle of the radiator needs to be adjusted in order to maintain the most economical air flow rate. In this case,

[0059] Where S'2=N*S2xsin9. From the this, it follows that: Q'S2=QS'2, that is, Q'S2=QN><S2xsin6. The adjustment angle 0 is calculated as: Q' 6 = arcsin — NQ

[0060] If Q' >Q, 0 needs to be increased to increase the flow area in order to maintain a constant flow rate. If increasing 0 to 180° still cannot maintain the desired flow rate, the flow rate of the hot fluid is reduced to match the cooling power. If Q' <Q, 0 needs to be decreased to reduce the flow area in order to maintain a constant flow rate. According to the above equation, this method effectively guides the adjustment of the included angle between adjacent heat dissipation assemblies 100, ensuring the most economical air flow rate is maintained, making the usage more scientific and rational.

[0061] The above are only preferred embodiments of the present application, and are not therefore intended to limit the patent scope of the present application, and any equivalent structure or equivalent process transformation made based on the description and drawings of the present application, or direct or indirect applications in other related technical fields, are all included in the patent protection scope of the present application.
