DETAILED DESCRIPTION
Refer to FIG. 1. FIG. 1 is a three-dimensional diagram of a flexible heat dissipation device according to some embodiments. A flexible heat dissipation device 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 portion 111 and a first end portion 112, and the first end portion 112 is connected to the first body portion 111. The second flexible heat dissipation strip 120 includes a second body portion 121 and a second end portion 122, and the second end portion 122 is connected to the second body portion 121. The first body portion 111 and the second body portion 121 form a strip winding portion 130, and the first end portion 112 is connected to the second end portion 122 to form a fitting portion 140.
During use, the fitting portion 140 of the flexible heat dissipation device 100 is configured to be in contact with a component to be dissipated (such as a heat source) for heat exchange. Then the fitting portion 140 conducts heat to the strip winding portion 130. Since the strip winding portion 130 has a large heat dissipation area and a gap allows airflows to pass through, the strip winding portion 130 may achieve a better heat dissipation effect.
Second, the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 may be made of a flexible material, and may be bent according to requirements to form the strip winding portion 130. For example, the flexible heat dissipation device 100 is manufactured by winding the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 to form the strip winding portion 130. In some embodiments, to wind the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 means to arrange in at least an overlapping position of the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120. When the flexible heat dissipation device is applied to, for example, a drone, a mixed reality helmet, or another apparatus with a narrow internal space, a user may apply a force to elongate or compress the strip winding portion 130 (that is a distance in a vertical direction from the perspective of FIG. 1) according to a space of a heat dissipation device in the apparatus, to adjust a size of the flexible heat dissipation device 100 to be adapted to the internal space of the apparatus. In addition, the user can also bend the strip winding portion 130 according to a shape of the space of the heat dissipation device for accommodation, and make corresponding adaptation, for example, make the strip winding portion 130 in an S-shape, an L-shape, or other shapes. Therefore, the user can fit the fitting portion 140 to a surface of a heat source in the apparatus to conduct heat to the strip winding portion 130. Since the airflow can pass through a gap generated after the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 are wound, heat generated by the heat source can be dissipated in the strip winding portion 130. Therefore, the flexible heat dissipation device 100 can not only change the size through the strip winding portion 130, but also maintain the heat dissipation effect.
Refer to FIG. 2. FIG. 2 is a partial enlarged view of a position marked by E in FIG. 1. The strip winding portion 130 includes a reduplicating section 131 (a section marked by A in FIG. 2). The reduplicating section 131 refers to a section from a peak of a bend to a peak of a next bend. A length of the reduplicating section 131 in a vertical direction in FIG. 2 is referred to as a section distance A. When the strip winding portion 130 is over-compressed, the first body portion 111 and the second body portion 121 are relatively close to each other. In this way, the section distance A becomes shorter, which reduces the gap for the airflow to pass through the strip winding portion 130. Conversely, the strip winding portion 130 is stretched to lengthen the section distance A, which can increase the gap between the strip winding portions 130 and improve the heat dissipation effect. In this way, the strip winding portion 130 has a sufficient gap for the airflow to pass through to maintain the heat dissipation effect. In some embodiments, a quantity of reduplicating sections 131 of the strip winding portion 130 may also be increased or reduced according to use requirements. For example, the quantity may be reduced to only 0.5 reduplicating sections 131 in one strip winding portion 130.
Still refer to FIG. 1. In some embodiments, the first flexible heat dissipation strip 110 further includes a first tail end portion 113, and the first tail end portion 113 is connected to an other end of the first body portion 111 that is relative to the first end portion 112, the second flexible heat dissipation strip 120 further includes a second tail end portion 123, and the second tail end portion 123 is connected to an other end of the second body portion 121 that is relative to the second end portion 122. In some embodiments, the first tail end portion 113 is connected to the second tail end portion 123, so that the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 are connected to each other. In some embodiments, the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 are not limited to connecting the first tail end portion 113 to the second tail end portion 123, and the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 may be connected to each other through winding of the first body portion 111 and the second body portion 121 and fitting of the first end portion 112 and the second end portion 122. Further, as shown in FIG. 1, a folded portion 150 is formed between the first tail end portion 113 and the second tail end portion 123. In some embodiments, the folded portion 150 is triangular and the fitting portion 140 is rectangular, but the present disclosure is not limited thereto. In the following manufacturing method, according to different included angles between the first tail end portion 113 and the second tail end portion 123, the folded portion 150 may also have different shapes. According to different shapes of the first end portion 112 and the second end portion 122, the fitting portion 140 may also have different shapes.
In the foregoing embodiments, the first flexible heat dissipation strip 110 and the second flexible heat dissipation strip 120 may each be an independent element, and may be connected to each other at the first tail end portion 113 and the second tail end portion 123 or may be connected to each other at the first end portion 112 and the second end portion 122.

Refer to FIG. 10 and FIG. 11. FIG. 10 is a three-dimensional diagram of a flexible heat dissipation device according to some embodiments. FIG. 11 is a partial enlarged view of a position marked by F in FIG. 10. The foregoing embodiment shows that the flexible heat dissipation device 100 is connected to the another flexible heat dissipation device 200 through the extending portion, but the present disclosure is not limited thereto.

Next, the overlapping portion where the first strip portion 331 and the second strip portion 333 bend is held and bent toward the second strip portion 333. Next, the first strip portion 331 is bent toward the opposite side. The actions of bending the overlapping portion where the first strip portion 331 and the second strip portion 333 bend and bending the first strip portion 331 toward the opposite side are repeated to complete the strip winding portion 340 formed by winding the first strip portion 331 and the second strip portion 333 as shown in FIG. 10.

As shown in FIG. 13, to prevent each heat dissipation element 330 from being arranged side by side on a same side and affecting the heat dissipation effect, the heat dissipation elements 330 are staggered in sequence on two sides of the base 310 to maintain a space for the airflow to pass through. In addition, as shown in FIG. 13, the first strip portion 331 further includes a first tail end portion 335, the first tail end portion 335 is connected to an other end of the first strip portion 331 that is relative to the first end portion 332, the second strip portion 333 further includes a second tail end portion 336, and the second tail end portion 336 is connected to an other end of the second strip portion 333 that is relative to the second end portion 334.
