It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0058] Embodiment 1:

[0059] Depend on Figure 1 As shown, this embodiment discloses a loop heat pipe heat dissipation structure, including an evaporation unit (recorded as a first evaporation unit 1), a steam pipeline (recorded as a first steam pipeline 2), a condensation unit (recorded as a first condensation unit 3) and a liquid pipeline (recorded as a first liquid pipeline 4); one end of the first steam pipeline 2 is connected to the steam outlet of the first evaporation unit 1, and the other end is connected to the steam inlet of the first condensation unit 3, one end of the first liquid pipeline 4 is connected to the liquid outlet of the first condensation unit 3, and the other end is connected to the liquid inlet of the first evaporation unit 1; wherein at least part of the pipe sections in the first steam pipeline 2 and at least part of the pipe sections in the first liquid pipeline are respectively set as hoses 5. In some other embodiments, all the pipe sections in the first steam pipeline 2 and all the pipe sections in the first liquid pipeline 4 are set as hoses 5; or, the first steam pipeline 2 includes multiple hoses 5, and the first liquid pipeline 4 includes multiple hoses 5; suitable for some products with multiple bending deformation structures. The above-mentioned hose 5 is made of flexible material, which can be a metal hose, a silicone hose, a rubber hose, etc.

[0060] The principle of circulating heat dissipation is as follows: the first evaporation unit 1 absorbs the heat from the hot end, and the liquid inside it turns into steam. The steam enters the first condensation unit 3 through the first steam pipeline 2 for heat exchange (heat extraction), and the steam releases the heat to turn into liquid and returns to the first evaporation unit 1 through the first liquid pipeline 4, completing a heat dissipation cycle. The arrangement of the hose 5 enables the heat dissipation structure of the loop heat pipe to cope with usage scenarios that require deformation or bending; it is convenient to make full use of the product's own surface area for effective heat dissipation, ensuring the heat dissipation effect.

[0061] Embodiment 2:

[0062] The heat dissipation principle of this embodiment is the same as that of the first embodiment, except that:

[0063] The first evaporation unit 1 in this embodiment can include a plurality of evaporators a( Figure 2 The first condensing unit 3 may include a plurality of parallel condensers b ( Figure 2There are three shown in the figure). Among them, the condenser b in this embodiment is a commonly used structure at present, and the specific working principle is the same as that of the prior art, which will not be described in detail here.

The second sealed shell 621 is provided with a liquid inlet B port 624 and a gas outlet B port 625 connected to the boiling heat exchange cavity. The gas outlet B port 625 is connected to the steam pipeline (the first steam pipeline 2 in this embodiment). The first pipeline 63 is arranged between the gas outlet A port 614 and the liquid inlet B port 624. One end of the second pipeline 64 is connected to the liquid outlet A port, and the other end is connected to the first pipeline 63. A pumping device 65, such as a piezoelectric pump or a peristaltic pump, is added to the second pipeline 64 to promote the flow of liquid. The working principle is as follows: the liquid in the liquid inlet cavity of the capillary wick evaporator 61 enters the intersection with the first pipeline 63 through the second pipeline 64 under the extrusion of the pumping device 65. The steam generated by the capillary wick evaporator 61 enters the first pipeline 63, and then pushes the liquid at the intersection into the boiling heat exchange cavity of the pool boiling evaporator 62. The boiling heat exchange bottom plate 622 is heated to generate boiling heat exchange and generate steam, which enters the first steam pipeline 2 through the gas outlet B port 625 and participates in the heat dissipation cycle of the loop heat pipe heat dissipation structure.

The working principle is: the liquid in the first liquid pipeline 4 is divided into two paths and enters the boiling cavity 73 and the liquid replenishing channel 76 for heat exchange, and the liquid absorbs heat and becomes steam, and then enters the first steam pipeline 2 through the first gas outlet 712 and the second gas outlet 714, and participates in the heat dissipation cycle of the loop heat pipe heat dissipation structure.

[0066] Embodiment three:

[0067] This embodiment discloses a specific implementation structure of a loop heat pipe heat dissipation structure, which has the same heat dissipation principle as the first and second embodiments, and the difference lies only in the specific structure; only the differences are described below:

In other embodiments, the hoses 5 on the first steam pipeline 2 and the first liquid pipeline 4 are respectively arranged on the upper and lower sides of the hinge 15. In addition, the hoses 5 can also be arranged on the same side or both sides of the hinge 15 according to the size of the space, as long as the installation position of the hoses 5 corresponds to the hinge 15 and can be deformed with the rotation and bending of the glasses leg 14, which will not be described in detail here.

[0071] This embodiment also discloses another type of smart glasses (referred to as the second smart glasses); Figure 8 As shown in FIG. 7 , the structure of the second smart glasses is basically the same as that of the first smart glasses, except that the heating component 16 is arranged in one of the glasses legs 14, the glasses legs 14 is the hot end, and the glasses body 13 is the cold end (compared with the smart glasses shown in FIG. 7 , the positions of the cold end and the hot end are interchanged); at this time, the first evaporation unit 1 is arranged in one of the glasses legs 14, the first condensation unit 3 is arranged in the glasses body 13, and the hose 5 is located at the hinge (hinge 15) between the glasses body 13 and the glasses legs 14.

[0072] Embodiment 4:

[0073] This embodiment discloses a specific implementation structure of a loop heat pipe heat dissipation structure, which has the same heat dissipation principle as the first and second embodiments, but differs in the specific structure; only the differences are described below:

[0084] The cyclic heat dissipation process is as follows: the first evaporation unit 1 absorbs the heat from the hot end, and the liquid therein becomes steam. The steam enters the first condensation unit 3 (to export part of the heat) and the second steam pipeline 10 through the first steam pipeline 2. The steam in the second steam pipeline 10 enters the second condensation unit 8 for heat exchange (to export part of the heat). After the steam releases the heat and becomes liquid, it enters the second liquid pipeline 11, and then converges with the liquid generated by the first condensation unit 3 to the first liquid pipeline 4, and returns to the first evaporation unit 1, completing a heat dissipation cycle.
