[0021] Referring to FIG. 1, FIG. 1 is a perspective view of a flexible heat sink according to this embodiment. The flexible heat sink 100 includes a first flexible heat sink strip 110 and a second flexible heat sink strip 120. The first flexible heat sink strip 110 has a first body 111 and a first bottom end 112, with the first bottom end 112 connected to the first body 111. The second flexible heat sink strip 120 has a second body 121 and a second bottom end 122, with the first bottom end 112 connected to the first body 111. The first body 111 and the second body 122 form an intersection 130. The first bottom end 112 and the second bottom end are connected to each other to form a bonding portion 140.

[0022] In use, the bonding portion 140 of the flexible heat sink 100 is brought into contact with a heat-generating component (e.g., a heat source) to exchange heat, which is then conducted from the bonding portion 140 to the intersection portion 130. The intersection portion 130 has a relatively large heat dissipation area and allows air to pass through the gap, so that the intersection portion 130 has a relatively good heat dissipation effect.

[0023] Next, the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 can be formed from a flexible material (a material that is easy to bend and does not break when bent), and can be bent as needed to form the intersection 130.

[0024] For example, the flexible heat sink 100 is fabricated by wrapping a first flexible heat sink strip 110 and a second flexible heat sink strip 120 around each other, forming an intersection 130. It can be formed.

[0025] Specifically, the first flexible heat dissipation strip 110 makes multiple U-turns in a first direction and then in a second direction opposite to the first direction, extending in the vertical direction as a whole. The second flexible heat dissipation strip 120 also extends in the vertical direction in the same manner. However, as shown in FIG. 1 , the second flexible strip 120 is offset by 90 degrees from the first flexible heat dissipation strip 110. Therefore, when the first flexible heat dissipation strip 110 makes a U-turn, the second flexible strip 120 extends so as to pass through the concave portion, and this is repeated throughout the entire vertical direction, thereby winding the first and second flexible heat dissipation strips together.

[0026] When applied to devices with limited internal space, such as drones or helmet-integrated mixed reality devices, the user can apply force to lengthen or shorten the intersection 130 to fit the heat sink space provided by the device, thereby adjusting the size of the flexible heat sink 100 (i.e., the vertical length when viewed from the angle of Figure 1) and making it fit the internal space of the device.

[0027] A user can also bend and adjust the intersection 130 to fit the shape of the space in which the flexible heat sink 100 is placed. For example, the intersection 130 may have an S-shape, an L-shape, or other shapes.

[0028] Therefore, the user can attach the bonding portion 140 to the surface of the heat source inside the device, and further, in order to conduct heat to the intersection portion 130, a space for air to flow can be formed in the gap that is created after wrapping the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120, so that the heat generated at the heat source can be dissipated at the intersection portion 130.

[0029] In this way, the flexible heat sink 100 can not only change its size by the intersection 130, but also maintain its heat dissipation effect.

[0030] Next, explanation will be made with reference to Fig. 2. Here, Fig. 2 is an enlarged view of a main part of the region E surrounded by the dashed line in Fig. 1. Intersection 130 includes reciprocating portion 131 (a section of inter-part distance A in Fig. 2), and reciprocating portion 131 is a section from the apex of a curved portion to the apex of the curved portion immediately below it, and the length of reciprocating portion 131 in the vertical direction in Fig. 2 is called inter-part distance A.

[0031] When the intersection 130 is strongly compressed, the first body 111 and the second body 121 move closer to each other, and at this time, the inter-part distance A becomes shorter, and the gap through which air can flow through the intersection 130 decreases.

[0032] Conversely, if the intersecting portions 130 are stretched to increase the inter-portion distance A, the gap between the intersecting portions 130 increases, improving the heat dissipation effect.

[0033] In this way, a gap sufficient for airflow to pass through is formed at the intersection 130, thereby maintaining heat dissipation effectiveness. Note that, depending on the embodiment, the number of reciprocating portions 131 at the intersection 130 can be increased or decreased depending on the conditions of use. For example, the number of reciprocating portions 131 at one intersection 130 can be reduced to only 0.5.

[0034] Referring again to Figure 1, in this embodiment, the first flexible heat-dissipating strip 110 further has a first tail end 113, which is connected to the first body 111 and faces the other end of the first bottom end 112. In short, the first tail end 113 and the first bottom end 112 are provided at both ends in the longitudinal direction of the substantially band-shaped (strip-shaped) first body 111 shown in FIG.

[0035] In this embodiment, the first tail end 113 connects to the second tail end 123, connecting the first flexible heat dissipation strip and the second flexible heat dissipation strip to each other.

[0036] In this embodiment, the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 are not limited to connecting the first tail end 113 to the second tail end 123, but may also be connected to each other by wrapping the first body 111 and the second body 121 around each other and bonding the first tail end 112 and the second tail end 122 together.

[0037] 1, a folded portion 150 is formed at the connection point between the first tail end 113 and the second tail end 123. In this embodiment, the folded portion 150 has a triangular shape, and the bonding portion 140 has a rectangular shape, but is not limited thereto.

[0038] In the manufacturing method described below, the included angle based on the first tail end 13 and the second tail end 123 is different, the shape of the folding portion 150 can also be changed, and the shape of the bonding portion 140 can also be changed based on the change in the shape of the first bottom end 112 and the second bottom end 122.

[0039] In the above-described embodiments, the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 can be independent components, with the first tail end 113 and the second tail end 123 connected together, or the first bottom end 112 and the second bottom end 122 connected together.

[0040] However, without being limited thereto, in other embodiments, the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 may be two regions of a single integrally formed strip-shaped part (hereinafter simply referred to as a "single part") (as shown in FIG. 3), and are formed by a winding method. A method for manufacturing such a flexible heat dissipation device 100 from this single strip-shaped part will be described with reference to FIGS. 3 to 6.

[0041] Next, explanation will be made with reference to Figures 3 to 6. Here, Figure 3 is a perspective view showing the flexible heat sink based on the embodiment of Figure 1 in an unfolded state. Also, Figure 4 is an explanatory diagram (1) of the manufacturing process of the flexible heat sink of the embodiment of Figure 1. Furthermore, Figure 5 is an explanatory diagram (2) of the manufacturing process of the flexible heat sink of the embodiment of Figure 1. Also, Figure 6 is an explanatory diagram (3) of the manufacturing process of the flexible heat sink of the embodiment of Figure 1.

[0042] The flexible heat sink in Fig. 3 is not yet bent to make repeated U-turns, i.e., it is shown in a state where it is unfolded in a straight line. First, as shown in Fig. 4, the second body 121 is bent so that the long axis C2 of the second body 121 is approximately perpendicular to the long axis C1 of the first body 111.

[0043] The side of the folded overlapping portion of the second body 121 and the first body 111 forms an angle of approximately 45 degrees with the long axis C1 of the first body 111 (i.e., the angle formed by the long axis C1 of the first body 111 and the long axis C2 of the second body 121 is 90 degrees).

[0044] Next, a description will be given with reference to FIG. 5. The first body 111 is attached to the opposite side (the second side in FIG. 3). The body 121 is bent toward the side where it was originally located.

[0045] Next, referring to Fig. 6, second body 121 is folded to the opposite side. Furthermore, by repeating the steps of Fig. 5 and Fig. 6, first body 111 and second body 121 are repeatedly overlapped as shown in Fig. 1, first body 111 and second body 121 are intertwined to form intersection 130, and first bottom end 112 and second bottom end 122 are connected to form bonded portion 140.

[0046] Referring again to FIG. 4, in this embodiment, the folded edge of the overlapping portion of the second body 121 and the first body 111 forms an angle of approximately 45 degrees with the long axis C1 of the first body 111, but this is not limited to this.

[0047] In this embodiment, the folded edge of the folded overlapping portion of the second body 121 and the first body 111 may form an included angle of approximately 25 degrees to 65 degrees with the long axis C1 of the first body 111 (i.e., the angle formed by the long axis C1 of the first body 111 and the long axis C2 of the second body 121 is 45 degrees to 135 degrees).

[0048] In this embodiment, the first body 111 and the second body 121 are repeatedly overlapped, so that excessive compression can be prevented, which would reduce the heat dissipation effect.

[0049] 1, in this embodiment, the first bottom end 112 and the second bottom end 122 overlap to form the bonded portion 140. In this embodiment, the first bottom end 112 is a square plane. The second bottom end 122 is also a square plane, and the two planes are overlapped and connected to form the bonded portion 140 having an overlapping surface, but this is not limiting.

[0050] The first bottom end 112 and the second bottom end 122 may each be a right-angled triangular plane, or may be formed by joining two right-angled triangular planes together to form a bonded portion 140 having a perfect square plane.

[0051] In this embodiment, the first bottom end 112 and the second bottom end 122 do not contact each other, that is, the two components are bonded to the heat-dissipating components, but their edges are adjacent to each other.

[0052] Next, a description will be given with reference to Figures 7 and 8. Figure 7 is a perspective view of a flexible heat sink based on this embodiment. Figure 8 is a perspective view showing another application example of the flexible heat sink of the embodiment of Figure 7.

[0053] In this embodiment, the flexible heat sink 100 is connected to another flexible heat sink 200. The other flexible heat sink 200 has the same structure as the flexible heat sink 100, so a redundant description will not be given here.

[0054] Another flexible heat sink 200 includes a third flexible heat dissipation strip 210 and a fourth flexible heat dissipation strip 220. The third flexible heat dissipation strip 210 has a third body 211 and a third bottom end 212. The third bottom end 212 is connected to the third body 211. The fourth flexible heat dissipation strip 220 has a fourth body 221 and a fourth bottom end 222. The fourth bottom end 222 is connected to the fourth body 221.

[0055] The third body 211 and the fourth body 221 form another intersection 230. The third bottom end 212 and the fourth bottom end 222 are connected to each other to form another bonded portion 240.

[0056] 7, in this embodiment, one of the first bottom end 112 and the second bottom end 122 extends a first extension 160. One of the third bottom end 212 and the fourth bottom end 222 extends a second extension 260. The first extension 160 is connected to the second extension 260.

[0057] In this way, structures forming a plurality of flexible heat sinks can be connected according to requirements such as heat dissipation and device structure.

[0058] In this embodiment, only the third flexible heat dissipation strip 210 and the fourth flexible heat dissipation strip 220 are shown as another flexible heat dissipation strip 200. However, this is not limited thereto, and a flexible heat dissipation strip (not shown) may be formed that further includes a fifth flexible heat dissipation strip and a sixth flexible heat dissipation strip in addition to the configuration shown in FIG.

[0059] As shown in FIG. 7, in this embodiment, the bonding unit 140 and another bonding unit 240 are located on the same plane, and can be applied to a device having a smooth surface, but is not limited to this.

[0060] 8, when this embodiment is used for a device with a curved or folded surface, a bending portion 170 is provided between the first extending portion 160 and the second extending portion 260, and when folded, the bonding portion 140 and the other bonding portion 240 are not coplanar, for example, they are positioned on two different intersecting planes, so that the bonding portion 140 and the other bonding portion 240 can be bonded to, for example, a device with a curved or folded surface.

[0061] As shown in Figures 7 and 8, in this embodiment, the flexible heat sink 100 and the other flexible heat sink 200 may be independent components, and the first extension portion 160 and the second extension portion 260 are connected to each other to form a single component (element), but this is not limited to this.

[0062] In this embodiment, the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 of the flexible heat sink 100 and the third flexible heat dissipation strip 210 and the fourth flexible heat dissipation strip 220 of the other flexible heat sink 200 are single strip-shaped parts, i.e., integrally formed heat dissipation strips.

[0063] The following description will be made with reference to FIG. 9. Here, FIG. 9 is a perspective view of a flexible heat sink based on this embodiment. In this embodiment, the first body 111 has a plurality of first holes 1111 arranged at equal intervals, and the second body 121 has a plurality of second holes 1211 arranged at equal intervals, and the plurality of first holes 1111 and the plurality of second holes 1211 are arranged in a staggered pattern at the intersection 130. Here, in FIG. 9, the first body 111 and the second body 121 have a structure in which they pass through a recess that makes a U-turn in the same manner as in FIG. 1, so the opening directions of the plurality of first holes 1111 and the plurality of second holes 1211 are also shifted by 90 degrees.

[0064] 9, the plurality of first holes 1111 of the intersection 130 are located at the vertices of the curved portions of the first body 111, and the plurality of second holes 1211 are located at the vertices of the curved portions of the second body 121, so by forming the first holes 1111 and second holes 1211 in a staggered arrangement, the heat dissipation effect of the flexible heat sink 100 due to the plurality of holes can be improved. That is, since the first holes 1111 and the second holes 1211 are each opened near the vertices of the U-shaped curve in cross section, heat is less likely to be trapped and the heat dissipation effect is improved. It becomes something.

[0065] Next, a description will be given with reference to Figures 10 and 11. Figure 10 is a perspective view of a flexible heat sink based on this embodiment, and Figure 11 is an enlarged view of a main part of the region F surrounded by a dashed line in Figure 10.

[0066] Although the above embodiment shows that the flexible heat sink 100 is connected to another flexible heat sink 200 via an extension portion (not numbered), this is not limited thereto. In this embodiment, the flexible heat sink 300 includes a base 310 and a plurality of heat dissipation components 330.

[0067] As shown in FIGS. 10 and 11, each of the heat dissipation components 330 of the flexible heat sink 300 includes a first foil-shaped portion 331, a first end portion 332, a second foil-shaped portion 333, and a second end portion 334.

[0068] The first end 332 is connected to the first thin plate portion 331, and the second end 334 is connected to the second thin plate portion 333. The first thin plate portion 331 and the second thin plate portion 333 form a strip intersection portion 340. The first end 332 and the second end 334 are connected to each other to form a bonding portion 350, and the bonding portion 350 is bonded to the base 310.

[0069] In this embodiment, the base 310 and the plurality of heat dissipation components 330 are formed as a single, integral component, but this is not limiting, and the base 310 and the plurality of heat dissipation components 330 may be separate components.

[0070] In this embodiment, the flexible heat sink 300 may be made of a flexible material, and a heat sink component 330 may be formed by bending a portion of the base 310, and the strip intersection 340 may be wrapped around the piece of the heat sink component 330 to complete a structure similar to the flexible heat sink 100. Further, the flexible heat sink 100 may be connected to another flexible heat sink 200 to be applied to the component to be dissipated heat.

[0071] As shown in FIG. 11, in this embodiment, the intersection portion 340 includes a reciprocating portion 341 (the region indicated by B in FIG. 11).

[0072] As shown in FIG. 11, the reciprocating section 341 is the section from the apex of one curved section to the apex of the next curved section, which prevents the intersection section 340 from being excessively compressed, and since the first thin section 331 and the second thin section 333 are in close contact with each other, it is difficult for air to flow through the gap at the intersection section 340, which also reduces the heat dissipation effect.

[0073] In this embodiment, the number of reciprocating portions 341 provided in the strip intersection 340 can be increased or decreased as needed, for example, the strip intersection 340 can have only 0.5 reciprocating portions 341. The winding method of the flexible heat sink 300 is shown in Figures 12 to 14.

[0074] The description will be made with reference to Figures 12 to 14. Here, Figure 12 is an explanatory diagram (1) of the manufacturing process of the flexible heat sink based on the embodiment of Figure 10.

[0075] 13 is a diagram (2) illustrating the manufacturing process of a flexible heat sink based on the embodiment of FIG. 10, and FIG. 14 is a diagram (3) illustrating the manufacturing process of a flexible heat sink based on the embodiment of FIG.

[0076] 12 shows the flexible heat sink 300 in an unfolded state. From this state, first, as shown in FIG. 13, parts of the base 310 are folded and overlapped, and parts of the left and right sides are folded in the same way.

[0077] Due to the multiple cutouts 390 on the base 310, the overlapping portions of the base 310 form multiple heat dissipation components 330, and the bent portions on the left and right sides also form multiple heat dissipation components 330.

[0078] Next, as shown in FIG. 14, when the first flake-shaped portion 331 is bent so that the long axis C3 of the first flake-shaped portion 331 is substantially perpendicular to the long axis C4 of the second flake-shaped portion 333, an angle of approximately 45 degrees is formed between the inclined side of the overlapping portion of the first flake-shaped portion 331 and the second flake-shaped portion 333 when bent and the long axis C4 of the second flake-shaped portion 333 (i.e., the angle between the long axis C3 of the first flake-shaped portion 331 and the long axis C4 of the second flake-shaped portion 333 is 90 degrees).

[0079] Then, the overlapping portion of the first thin plate portion 331 and the second thin plate portion 333 is held and folded toward the second thin plate portion 333. Then, the first thin plate portion 331 is folded in the opposite direction.

[0080] By repeating the operation of folding the overlapping portion of the first thin film portion 331 and the second thin film portion 333 and the operation of folding the first thin film portion 331 in the opposite direction, a strip-shaped intersection portion 340 is completed, in which the first thin film portion 331 and the second thin film portion 333 are wound together, as shown in Figure 10.

[0081] In this way, different structural states can be achieved through the flexible heat sink 300 according to the shape and heat dissipation requirements of the device used for heat dissipation.

[0082] Referring again to Figure 10, the description will be made. In this embodiment, the base 310 includes a first body 310A and a second body 310B on both sides. In this embodiment, one of the bonding portions 350 is bonded to the first body 310A, and the other of the bonding portions 350 is bonded to the second body 310B.

[0083] 13, it is inevitable that the heat dissipation components 330 are arranged side by side on the same side, which will affect the heat dissipation effect. The heat dissipation components 330 are attached in a staggered pattern on both sides of the base 310 in order to maintain a space for air to flow through.

[0084] Also, as shown in FIG. 13 , the first flake-shaped portion 331 has a first tail end 335, which is connected to the other end opposite the first end 332 of the first flake-shaped portion 331, and the second flake-shaped portion 333 has a second tail end 336, which is connected to the other end opposite the second end 334 of the second flake-shaped portion 333, and the first tail end 335 is connected to the second tail end 336.

[0085] 14, in this embodiment, the side of the overlapping portion of the first thin plate portion 331 and the second thin plate portion 333 forms an angle of approximately 45 degrees with the long axis C4 of the second thin plate portion 333. Although the folded portion 360 is triangular and the bonding portion 350 is rectangular, these are not limited thereto, and the folded portion 360 can have a different shape depending on the included angle.

[0086] Next, a description will be given with reference to Fig. 15. Here, Fig. 15 is a perspective view of a flexible heat sink based on this embodiment.

[0087] The first slice portion 331 has a plurality of equally spaced first openings 3311, and the second slice portion 333 has a plurality of equally spaced second openings 3331, with the plurality of first openings 3311 and the plurality of second openings 3331 being staggered at the strip intersections 340.

[0088] 15 , the plurality of first openings 3311 at the strip intersection 340 are located at the vertices of the curved portions of the first slice-shaped portion 331. The plurality of second openings 3331 are located at the vertices of the curved portions of the second slice-shaped portion 333. In this way, the first openings 3311 and the second openings 3331 are formed in a staggered arrangement, and the heat dissipation effect of the heat dissipation component 330 is improved through the plurality of openings.

[0089] Referring again to FIG. 10, in this embodiment, the heat dissipation component 330 connected to the left side of the first body 310A and the right side of the second body 310B in FIG. 10 may be, for example, the flexible heat sink 100 in the above-described embodiment.

[0090] For example, either the first bottom end 112 or the second bottom end 122 of the flexible heat sink 100 is connected to the base 310, and the above-mentioned winding process is carried out.

[0091] Furthermore, the bonding portion 140 of the flexible heat sink 100 after the winding is completed is bonded to the base 310. In this embodiment, the flexible heat sink 100 and the flexible heat sink 300 can be formed in the same manner as the manufacturing method of the flexible heat sink 100, by punching a strip-shaped material into a plurality of strip-shaped parts to form an integrated body, and then winding the strip-shaped parts together.

[0092] As described above, in this embodiment, a flexible heat sink is provided, in which a first flexible heat sink strip and a second flexible heat sink strip are wound alternately to form an intersection, and can be attached to a device using a bonding portion.

[0093] Furthermore, due to its flexibility, the flexible heat sink can be applied to various devices, and can be bent into an appropriate shape to match the shape and structure of the internal space of the device. [Explanation of symbols]
