Embodiments for Carrying Out the Invention

[0021] A description will be given with reference to FIG. 1. Here, FIG. 1 is a perspective view of a flexible radiator according to the present embodiment. The flexible radiator 100 includes a first flexible heat dissipation strip 110 and a second flexible heat dissipation strip 120. The first flexible heat dissipation strip 110 includes a first body 111 and a first bottom end portion 112, and the first bottom end portion 112 is connected (joined) to the first body 111. The second flexible heat dissipation strip 120 includes a second body 121 and a second bottom end portion 122, and the first bottom end portion 112 is connected to the first body 111. The first body 111 and the second body 122 form an intersection portion 130. The first bottom end portion 112 and the second bottom end portion are connected to each other to form an attachment portion 140.

[0022] In use, the attachment portion 140 of the flexible radiator 100 is used to contact a heat-generating component (e.g., a heat source), and heat exchange is performed. Subsequently, the attachment portion 140 conducts heat to the intersection portion 130. The intersection portion 130 has a relatively large heat dissipation area, and air can pass through the gaps therein. Therefore, a relatively excellent heat dissipation effect can be obtained for the intersection portion 130.

[0023] Subsequently, the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 can be formed of a flexible material (a material that is easy to bend and not easily broken even when bent repeatedly), and can be bent as needed to form the intersection portion 130.

[0024] For example, the flexible radiator 100 can be manufactured by winding the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 around each other to form the intersection portion 130.

[0025] Specifically, the first flexible heat dissipation strip 110 repeatedly makes a U-turn a plurality of times in the first direction and the second direction opposite to the first direction, and extends vertically as a whole. Similarly, the second flexible heat dissipation strip 120 also extends vertically. However, as shown in FIG. 1, the second flexible strip is offset by 90 degrees with respect to the first flexible heat dissipation strip 110. Therefore, when the first flexible heat dissipation strip 110 makes a U-turn, the second flexible heat dissipation strip 120 extends so as to pass through a portion that is exactly concave, and by repeating this over the entire vertical direction, they are wound around each other.

[0026] When applied to devices with a narrow internal space such as drones and helmet-integrated mixed reality devices, the user can apply force to stretch the intersection 130 long or shorten the intersection 130 so as to fit the space of the radiator provided by the device, and adjust the size of the flexible radiator 100 (that is, the length in the vertical direction when viewed from the angle in FIG. 1) to fit the internal space of the device.

[0027] In addition, the user can also adjust by bending the intersection 130 to fit the shape of the space where the flexible radiator 100 is arranged. 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 in the device. Furthermore, in order to conduct heat to the intersection 130, a space through which air can flow can be formed in the gap generated after winding the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120, so that the heat generated by the heat source can be dissipated at the intersection 130.

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

[0030] Next, a description will be given with reference to FIG. 2. Here, FIG. 2 is an enlarged view of the main part of the region E surrounded by the one-dot chain line in FIG. 1. The intersection portion 130 includes a reciprocating portion 131 (the section of the partial distance A in FIG. 2), and the reciprocating portion 131 is the section from the apex of the curved portion to the apex of the immediately lower curved portion, and the length in the vertical direction of the reciprocating portion 131 in FIG. 2 is referred to as the partial distance A.

[0031] When the intersection portion 130 is strongly compressed, the first body 111 and the second body 121 approach each other. At this time, the partial distance A becomes shorter, and the gap through which air flows through the intersection portion 130 decreases.

[0032] Conversely, when the intersection portion 130 is stretched to increase the partial distance A, the gap between the intersection portions 130 becomes larger, so the heat dissipation effect is improved.

[0033] In this way, a sufficient gap for the air flow to pass through is formed in the intersection portion 130, so the heat dissipation effect is maintained. Depending on the embodiment, it can be increased or decreased based on the conditions for using the number of reciprocating portions 131 of the intersection portion 130. For example, the number of reciprocating portions 131 in one intersection portion 130 can be reduced to only 0.5.

[0034] A description will be given again with reference to FIG. 1. In the present embodiment, the first flexible heat dissipation strip 110 further has a first tail end portion 113, and the first tail end portion 113 is connected to the first body 111 and is opposite to the other end of the first bottom end portion 112. In short, the first tail end portion 113 and the first bottom end portion 112 are provided at both ends in the longitudinal direction of the substantially strip-shaped (strip-shaped) first body 111 shown in FIG. 3 to be described later.

[0035] In the present embodiment, the first tail end portion 113 is connected to the second tail end portion 123 to connect 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 the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 may 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 junction of 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 folded 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-mentioned 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 (as shown in FIG. 3) of a single integrally formed strip-shaped part (hereinafter also simply referred to as a "single part"), and a method for manufacturing such a flexible heat sink 100 from this single strip-shaped part is described in FIGS. 3 to 6.

[0041] Next, a description will be given with reference to FIGS. 3 to 6. Here, FIG. 3 is a perspective view showing a state in which the flexible radiator according to the embodiment of FIG. 1 is deployed. FIG. 4 is an explanatory diagram (one) of the manufacturing process of the flexible radiator according to the embodiment of FIG. 1. Further, FIG. 5 is an explanatory diagram (two) of the manufacturing process of the flexible radiator according to the embodiment of FIG. 1. FIG. 6 is an explanatory diagram (three) of the manufacturing process of the flexible radiator according to the embodiment of FIG. 1.

[0042] The flexible radiator in FIG. 3 is not yet bent so as to repeat a U-turn, that is, it shows a state of being deployed linearly. First, as shown in FIG. 4, the second body 121 is bent so that the major axis C2 of the second body 121 is substantially orthogonal to the major axis C1 of the first body 111.

[0043] The side of the folded and overlapping portion of the second body 121 and the first body 111 and the major axis C1 of the first body 111 form an angle of about 45 degrees (that is, the angle formed by the major axis C1 of the first body 111 and the major axis C2 of the second body 121 is 90 degrees).

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

[0045] Subsequently, referring to FIG. 6, the second body 121 is bent to the opposite side. Further, the steps of FIGS. 5 to 6 are repeated, and as shown in FIG. 1, the first body 111 and the second body 121 are repeatedly overlapped, the first body 111 and the second body 121 are intertwined to form an intersection 130, and the first bottom end 112 and the second bottom end 122 are connected to form a bonding portion 140.

[0046] Referring to FIG. 4 again, in the present embodiment, it is shown that the folded side of the portion where the second body 121 and the first body 111 are folded and overlapped and the major axis C1 of the first body 111 form an angle of about 45 degrees, but it is not limited thereto.

[0047] In this embodiment, the folded side of the overlapping portion of the second body 121 and the first body 111 and the major axis C1 of the first body 111 may form an included angle of about 25 degrees to 65 degrees (that is, the angle formed by the major axis C1 of the first body 111 and the major axis C2 of the second body 121 is 45 degrees to 135 degrees).

[0048] In this embodiment, since the first body 111 and the second body 121 overlap repeatedly, it is possible to prevent excessive compression and a reduction in the heat dissipation effect.

[0049] Referring to FIG. 1 again, in this embodiment, the first bottom end portion 112 and the second bottom end portion 122 overlap to form a bonding portion 140. The first bottom end portion 112 of this embodiment has a square plane. The second bottom end portion 122 is also a square plane, and by overlapping and connecting the two planes, a bonding portion 140 having an overlapping surface is formed, but it is not limited thereto.

[0050] The first bottom end portion 112 and the second bottom end portion 122 may each be a right-angled triangle plane, and are formed by connecting the two right-angled triangle planes, and a bonding portion 140 having a complete square plane may be formed.

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

[0052] Next, a description will be given with reference to FIGS. 7 and 8. FIG. 7 is a perspective view of a flexible radiator according to this embodiment. FIG. 8 is a perspective view showing another application example of the flexible radiator of the embodiment of FIG. 7.

[0053] In this embodiment, the flexible radiator 100 is connected to another flexible radiator 200. Since the other flexible radiator 200 has the same structure as the flexible radiator 100, a repeated description will not be given here.

[0054] The other flexible radiator 200 includes a third flexible heat dissipation strip 210 and a fourth flexible heat dissipation strip 220. The third flexible heat dissipation strip 210 includes 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 includes 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 bonding portion 240.

[0056] As shown in FIG. 7, in this embodiment, either one of the first bottom end 112 and the second bottom end 122 extends the first extension portion 160. Either one of the third bottom end 212 and the fourth bottom end 222 extends the second extension portion 260. The first extension portion 160 is connected to the second extension portion 260.

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

[0058] In this embodiment, only the third flexible heat dissipation strip 210 and the fourth flexible heat dissipation strip 220 are shown as the other flexible radiator 200. However, it is not limited thereto. In addition to the configuration shown in FIG. 7, a flexible radiator (not shown) further including a fifth flexible heat dissipation strip and a sixth flexible heat dissipation strip may be formed.

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

[0060] As shown in FIG. 8, in the present embodiment, when used in a device with a curved surface or a bent surface, a bending portion 170 is provided between the first extension portion 160 and the second extension portion 260. When bent, the bonding portion 140 and the other bonding portion 240 are in non-coplanar planes. For example, they are located on two different intersecting planes. Thereby, the bonding portion 140 and the other bonding portion 240 can be bonded to a device with a curved surface or a bent surface, for example.

[0061] As shown in FIGS. 7 and 8, in the present embodiment, the flexible radiator 100 and the other flexible radiator 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 it is not limited thereto.

[0062] In the present embodiment, the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 of the flexible radiator 100, and the third flexible heat dissipation strip 210 and the fourth flexible heat dissipation strip 220 of the other flexible radiator 200 are single strip-shaped components, that is, integrally formed heat dissipation strips.

[0063] This will be described with reference to FIG. 9. Here, FIG. 9 is a perspective view of the flexible radiator according to the present embodiment. In the present embodiment, the first body 111 has a plurality of first holes 1111 arranged at equal intervals, 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 manner at the intersection portion 130. Here, in FIG. 9, since the first body 111 and the second body 121 have a structure passing through the recesses that make a U-turn in the same manner as in FIG. 1, the opening directions of the plurality of first holes 1111 and the plurality of second holes 1211 are also shifted by 90 degrees.

[0064] As shown in FIG. 9, a plurality of first holes 1111 of the intersection portion 130 are respectively located at the vertices of the curved portions of the first body 111, and a plurality of second holes 1211 are respectively located at the vertices of the curved portions of the second body 121. Therefore, by forming the first holes 1111 and the second holes 1211 that are staggeredly positioned, the heat dissipation effect of the flexible radiator 100 by the plurality of holes can be enhanced. That is, since the first holes 1111 and the second holes 1211 are respectively opened near the vertices of the U-shaped curve in a cross-sectional view, heat is less likely to accumulate, and the heat dissipation effect becomes more excellent.

[0065] Next, it will be described with reference to FIGS. 10 and 11. Here, FIG. 10 is a perspective view of a flexible radiator according to the present embodiment, and FIG. 11 is an enlarged view of a main part of the region F surrounded by the dashed line in FIG. 10.

[0066] The above embodiment shows that the flexible radiator 100 is connected to another flexible radiator 200 via an extension part (not labeled), but it is not limited thereto. In the present embodiment, the flexible radiator 300 includes a base 310 and a plurality of heat dissipation components 330.

[0067] As shown in FIGS. 10 and 11, each of the plurality of heat dissipation components 330 of the flexible radiator 300 includes a first flaky part 331, a first end part 332, a second flaky part 333, and a second end part 334.

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

[0069] In the present embodiment, the base 310 and the plurality of heat dissipation components 330 are integrally formed single components, but it is not limited thereto. The base 310 and the plurality of heat dissipation components 330 may be independent components respectively.

[0070] In this embodiment, the flexible radiator 300 may be formed of a flexible material, or a heat radiating component 330 may be formed by bending a part of the base 310, and the strip crossing portion 340 is wound around the sheet-like portion of the heat radiating component 330 to complete a structure similar to that of the flexible radiator 100. Further, by connecting the flexible radiator 100 and another flexible radiator 200, it is applied to the component to be cooled.

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

[0072] As shown in FIG. 11, the reciprocating portion 341 is an interval from the apex of the curved portion to the apex of the next curved portion, preventing the crossing portion 340 from being excessively compressed. Since the first sheet-like portion 331 and the second sheet-like portion 333 are in close contact, it is difficult for air to flow through the gap of the crossing portion 340, and the heat dissipation effect is also reduced.

[0073] In this embodiment, the number of the reciprocating portions 341 included in the strip crossing portion 340 may be increased or decreased as needed. For example, the strip crossing portion 340 may have only 0.5 reciprocating portion 341. The winding method of the flexible radiator 300 is shown in FIGS. 12 to 14.

[0074] This will be described with reference to FIGS. 12 to 14. Here, FIG. 12 is an explanatory diagram (one) of the manufacturing process of the flexible radiator based on the embodiment of FIG. 10.

[0075] FIG. 13 is an explanatory diagram (two) of the manufacturing process of the flexible radiator based on the embodiment of FIG. 10, and FIG. 14 is an explanatory diagram (three) of the manufacturing process of the flexible radiator based on the embodiment of FIG. 10.

[0076] FIG. 12 shows the state of the flexible radiator 300 in an unfolded state. From this state, first, as shown in FIG. 13, a part of the base 310 is folded and overlapped, and a part on the left and right sides is bent in the same way.

[0077] Due to a plurality of cut grooves 390 on the base 310, the overlapping part of the base 310 forms a plurality of heat dissipation components 330, and the bent parts on the left and right sides also form a plurality of heat dissipation components 330.

[0078] Next, as shown in FIG. 14, when the first flaky part 331 is bent so that the major axis C3 of the first flaky part 331 is substantially orthogonal to the major axis C4 of the second flaky part 333, an angle of about 45 degrees is formed between the inclined side of the overlapping part when the first flaky part 331 and the second flaky part 333 are bent and the major axis C4 of the second flaky part 333 (that is, the angle formed by the major axis C3 of the first flaky part 331 and the major axis C4 of the second flaky part 333 is 90 degrees).

[0079] Then, with the part where the first flaky part 331 and the second flaky part 333 are bent and overlapped, it is bent toward the second flaky part 333 side. And the first flaky part 331 is bent to the opposite side.

[0080] By repeating the operation of bending the overlapping part of the first flaky part 331 and the second flaky part 333 and the operation of bending the first flaky part 331 to the opposite side, as shown in FIG. 10, the strip-shaped intersection part 340 formed by winding the first flaky part 331 and the second flaky part 333 is completed.

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

[0082] Referring back to FIG. 10 for description. In the present embodiment, the base 310 includes a first main body 310A and a second main body 310B on both sides. In the present embodiment, either one of each bonding portion 350 is bonded to the first main body 310A, and the other of each bonding portion 350 is bonded to the second main body 310B.

[0083] As shown in FIG. 13, it is inevitable that each heat dissipation component 330 is arranged side by side on the same side, which affects the heat dissipation effect. Each heat dissipation component 330 is alternately attached to both sides of the base 310 in a staggered manner to maintain a space through which the air flow passes.

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

[0085] As shown in FIG. 14, in this embodiment, the side of the overlapping portion where the first flake-shaped portion 331 and the second flake-shaped portion 333 are folded forms an angle of about 45 degrees with the major axis C4 of the second flake-shaped portion 333. The folding portion 360 is formed in a triangle, and the bonding portion 350 is formed in a rectangle, but it is not limited thereto. Depending on the included angle, the folding portion 360 can also have different shapes.

[0086] Next, description will be made with reference to FIG. 15. Here, FIG. 15 is a perspective view of the flexible heat sink according to the present embodiment.

[0087] The first flake-shaped portion 331 has a plurality of first openings 3311 arranged at equal intervals, and the second flake-shaped portion 333 has a plurality of second openings 3331 arranged at equal intervals. The plurality of first openings 3311 and the plurality of second openings 3331 are arranged in a staggered manner at the strip intersection portion 340.

[0088] As shown in FIG. 15, a plurality of first openings 3311 in the strip intersection 340 are respectively located at the apexes of the curved portions of the first flaky portion 331. The plurality of second openings 3331 are respectively located at the apexes of the curved portions of the second flaky portion 333. In this way, the first openings 3311 and the second openings 3331 arranged in a staggered pattern are formed, and the heat dissipation effect of the heat dissipation component 330 is improved through the plurality of openings.

[0089] Referring to FIG. 10 again, in this embodiment, the heat dissipation component 330 connected to the left side of the first main body 310A and the right side of the second main body 310B in FIG. 10 can be, for example, the flexible radiator 100 in the foregoing embodiment.

[0090] For example, either one of the first bottom end portion 112 and the second bottom end portion 122 of the flexible radiator 100 is connected to the base 310, and the above-described winding process is executed.

[0091] Furthermore, the bonding portion 140 of the flexible radiator 100 after the winding is completed is bonded onto the base 310. In this embodiment, the flexible radiator 100 and the flexible radiator 300 may be integrally formed.

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

[0093] In addition, due to its flexibility, the flexible radiator can be applied to various devices and can also be bent into an appropriate shape according to the shape and structure of the internal space of the device.
