DESCRIPTION OF EMBODIMENTS
[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0031] FIG. 2 is a schematic structural diagram of Embodiment 1 of an intelligent terminal heat dissipation apparatus according to the present invention. FIG. 3 is a schematic diagram of a capillary structure in the intelligent terminal heat dissipation apparatus shown in FIG. 2. In this embodiment, capillary structures in the heat dissipation apparatus are usually multiple bundles of bendable metal wires that are winded by multiple lines and that traverse a rigid part and a flexible part to form continuous capillary structures, so that a cooled liquid flows back by means of a capillary force to an evaporation end for evaporation again. In this embodiment, the intelligent terminal heat dissipation apparatus may be applied to an intelligent terminal for heat dissipation and may be further applied to a bendable intelligent wearable terminal and a further bendable smartphone for heat dissipation.
[0032] The intelligent terminal heat dissipation apparatus includes: at least one flexible heat pipe, that is, the intelligent terminal heat dissipation apparatus may include one flexible heat pipe or multiple flexible heat pipes. When an intelligent terminal body includes multiple heating devices, multiple flexible heat pipes may be used, and the multiple flexible heat pipes may be connected in parallel or in series. It should be noted that the flexible heat pipe in this embodiment may be replaced by a high heat conducting material, such as a built-in copper foil, graphite tube, or high heat conducting braided fabric, but a heat pipe is preferred. In this embodiment, when the intelligent terminal heat dissipation apparatus includes one flexible heat pipe, as shown in FIG. 2, two ends of the flexible heat pipe are condensation ends 201, and the middle of the flexible heat pipe is an evaporation end 202. The condensation ends 201 on the two ends of the flexible heat pipe may include one heat pipe rigid part and multiple heat pipe flexible parts that are arranged alternately, or multiple heat pipe rigid parts and multiple heat pipe flexible parts that are arranged alternately, or multiple heat pipe rigid parts and one heat pipe flexible part that are arranged alternately, or one heat pipe rigid part and one heat pipe flexible part that are arranged alternately. Specifically, the condensation end may be set according to a structure of an intelligent terminal related in actual application, and this is not limited in this embodiment. The evaporation end 202 in the middle of the flexible heat pipe may include only a heat pipe rigid part or may include a heat pipe rigid part and a heat pipe flexible part, and FIG. 2 shows only a rigid part of the evaporation end 202. In this embodiment, all flexible parts are formed by multiple sections of hoses. In this embodiment, as shown in FIG. 3, a capillary structure 30 is disposed in the flexible heat pipe. The capillary structure 30 is a flexible sealed device by using a vacuum design. The capillary structure 30 is filled with an evaporable liquid with a low boiling point. When the intelligent terminal body is mounted on the evaporation end 202 of the flexible heat pipe and starts to work, the evaporation end 202 of the flexible heat pipe is heated, and a liquid on the evaporation end 202 can evaporate quickly. Under a small pressure difference, vapor flows to the two condensation ends 201 of the flexible heat pipe, and releases heat and condenses into a liquid again. The liquid flows back to the evaporation end 202 by means of a capillary force of a multihole capillary material, and circulation goes on likewise, to dissipate heat for a heat source of the intelligent terminal body by means of heat conduction. In this embodiment, because the condensation end includes one or more heat pipe rigid parts and one or more heat pipe flexible parts, flexible heat dissipation can be performed for a bendable device.
[0033] According to the intelligent terminal heat dissipation apparatus provided in this embodiment of the present invention, the intelligent terminal heat dissipation apparatus has condensation ends disposed on two ends of a flexible heat pipe and an evaporation end disposed in the middle of the flexible heat pipe. In addition, the condensation end includes one or more heat pipe rigid parts and one or more heat pipe flexible parts that are arranged alternately. The evaporation end includes at least one heat pipe rigid part. Therefore, flexible heat dissipation is implemented for a bendable device having many bent areas, thereby resolving a technical problem that a heat dissipation effect is relatively poor when an existing heat dissipation device dissipates heat for a bendable device having many bent areas.
[0034] FIG. 4 is a schematic structural diagram of Embodiment 2 of an intelligent terminal heat dissipation apparatus according to the present invention. Based on the foregoing embodiment, in this embodiment, the intelligent terminal heat dissipation apparatus includes multiple flexible heat pipes. To describe a relationship between the multiple flexible heat pipes, an example in which the intelligent terminal heat dissipation apparatus includes two flexible heat pipes is used for description in this embodiment. As shown in FIG. 4, the intelligent terminal heat dissipation apparatus includes: a first flexible heat pipe 41 and a second flexible heat pipe 42. The first flexible heat pipe 41 and the second flexible heat pipe 42 are distributed in parallel. An intelligent terminal body 43 may be mounted on an evaporation end of the first flexible heat pipe 41, or on an evaporation end of the second flexible heat pipe 42, or on an evaporation end of the first flexible heat pipe 41 and on an evaporation end of the second flexible heat pipe 42. Specifically, a mounting position may be selected according to a size of the intelligent terminal body 43. When the intelligent terminal body 43 is mounted on the evaporation end of the first flexible heat pipe 41 and the evaporation end of the second flexible heat pipe 42, the evaporation end of the first flexible heat pipe 41 and the evaporation end of the second flexible heat pipe 42 can perform heat dissipation for different heat sources of the same intelligent terminal body 43. For capillary structures in the two flexible heat pipes in this embodiment, reference may be made to distribution of the capillary structure 30 shown in FIG. 3.
[0035] FIG. 5 is a schematic structural diagram of Embodiment 3 of an intelligent terminal heat dissipation apparatus according to the present invention. FIG. 6 is a schematic diagram A of a capillary structure in the intelligent terminal heat dissipation apparatus shown in FIG. 5. FIG. 7 is a schematic diagram B of a capillary structure in the intelligent terminal heat dissipation apparatus shown in FIG. 5. Based on the foregoing embodiment, in this embodiment, the intelligent terminal heat dissipation apparatus includes multiple flexible heat pipes. To describe a relationship between the flexible heat pipes, an example in which the intelligent terminal heat dissipation apparatus includes two flexible heat pipes is used for description. In this embodiment, as shown in FIG. 5, the intelligent terminal heat dissipation apparatus includes a first flexible heat pipe 51 and a second flexible heat pipe 52. An evaporation end of the first flexible heat pipe 51 and an evaporation end of the second flexible heat pipe 52 are interconnected in series, that is, the evaporation end of the first flexible heat pipe 51 and the evaporation end of the second flexible heat pipe 52 are communicated. An intelligent terminal body 53 may be mounted on the evaporation end of the first flexible heat pipe 51 and/or the evaporation end of the second flexible heat pipe 52. In this embodiment, a first capillary structure 54 in the first flexible heat pipe 51 and a second capillary structure 55 in the second flexible heat pipe 52 are shown in FIG. 6. The first capillary structure 54 and the second capillary structure 55 are interconnected by using a third capillary structure 56a at a serial connection point between the evaporation end of the first flexible heat pipe 51 and the evaporation end of the second flexible heat pipe 52. To more fully dissipate heat for devices in the intelligent terminal body 53, the third capillary structure 56a is of a mesh structure. In this embodiment, the evaporation end of the first flexible heat pipe 51 and the evaporation end of the second flexible heat pipe 52 are interconnected in series, and the first capillary structure 54 in the first flexible heat pipe 51 and the second capillary structure 55 in the second flexible heat pipe 52 are also interconnected in series. Therefore, there are more capillary structures to dissipate heat for different heat sources of the same intelligent terminal body 53, and a heat dissipation effect is improved.
[0036] Further, in this embodiment, a connection relationship between the first capillary structure 54 in the first flexible heat pipe 51 and the second capillary structure 55 in the second flexible heat pipe 52 is shown in FIG. 7. The first capillary structure 54 and the second capillary structure 55 are connected in parallel, and multiple fourth capillary structures 56b are disposed between the evaporation end of the first flexible heat pipe 51 and the evaporation end of the second flexible heat pipe 52. The fourth capillary structures 56b are disposed vertically. That is, when the intelligent terminal body 53 is mounted on the evaporation end of the first flexible heat pipe 51 and the evaporation end of the second flexible heat pipe 52 and starts to work, a heated liquid that is on the top of the fourth capillary structure 56b and that is close to a heat source of the intelligent terminal body 53 evaporates, and vapor vertically flows to the bottom of the fourth capillary structure 56b and releases heat and condenses into a liquid again. The liquid flows back to the top of the fourth capillary structure 56b by means of a capillary force of a multihole capillary material, and circulation goes on likewise, to dissipate heat for the heat source of the intelligent terminal body 53. For a heat dissipation manner of the fourth capillary structure 56b, reference may be made to an existing cold plate heat dissipation technology.

It should be noted that in this embodiment, the mobile terminal heat dissipation apparatus 80 may act as a wrist strap, a watch strap, or a lanyard of an intelligent wearable terminal, that is, a user can use a body of the intelligent wearable terminal when it is mounted on the mobile terminal heat dissipation apparatus 80.
