Referring to fig. 1 to 5, the present invention provides a liquid cooling tube 100 for heat dissipation of a mobile phone, which includes an evaporation end 11, a condensation end 13, and a connecting portion 12 connecting the evaporation end 11 and the condensation end 13. The liquid cooling pipe 100 is arranged in a sealing manner. The liquid-cooled tube further comprises an inner cavity 4, a flowing medium (not shown) disposed within the inner cavity 4, and a core structure 3 disposed within the inner cavity 4. The wick structure 3 extends from an evaporation end 11 to a condensation end 13. The wick structure 3 is provided with a plurality of capillary holes, and the cooling liquid at the condensation end 13 is sucked to the evaporation end 11 through the capillary holes 3.

In use, the evaporation end 11 is connected to a heating element (not shown). The heat generated by the heating element is transferred to the evaporation end 11, and the cooling medium inside the evaporation end 11 absorbs the heat and then is converted from liquid to gas, so that the heat is absorbed. The cooling medium that has become a gas flows through the connection 12 to the condensation end 13, where the cooling medium changes from a gaseous state to a liquid state, thereby releasing heat. The cooling medium that has become liquid flows back from the condensation end 13 to the evaporation end 11 by capillary action of the wick structure 3. This setting can make the quick flow away of the heat that heating element produced to can play better radiating effect to heating element.

Fig. 2 to 5 show schematically a core structure 3. In practical products, the core structure 3 may have other shapes, and the specific structure is not limited. The core structure 3 includes a plurality of copper fibers 31 arranged side by side along the axial direction of the liquid cooling pipe 100, and the copper fibers 31 are fixed to the inner surface of the pipe portion 2 of the liquid cooling pipe 100 by sintering. Capillary pores are formed between the copper fibers 31. Preferably, the material of the tube portion 2 is copper. Copper has a good heat dissipation effect, and a part of heat generated by the heating element can be rapidly transferred to the liquid cooling end 13 through the copper fibers 31.

In order to obtain better heat dissipation effect, the core structure 3 further includes carbon fibers 32 which are only provided at the evaporation end 11, and one side of which is covered with the copper fibers 31 and the other side of which is attached to the inner surface of the pipe portion 2 of the liquid cooling pipe 100. The carbon fiber 32 is fixed to the inner wall of the liquid-cooling pipe 100 by the copper fiber 31. Since carbon has a higher melting point than copper, in the present embodiment, the copper fibers 31 are fixed to the inner surface of the tube portion 2 by sintering. The carbon fibers 32 are fixed to the inner surface of the tube portion 2 by the copper fibers 31. Since carbon has a better heat dissipation effect than copper, heat generated from the heating element can be rapidly transferred from the evaporation end 11 to the condensation end 13. In addition, the pore diameter of the capillary pores formed between the carbon fibers 32 is smaller than the pore diameter of the capillary pores formed between the copper fibers 31. This arrangement makes the capillary force of the capillary pores between the carbon fibers 32 larger than that between the copper fibers 31, so that the cooling fluid can be quickly drawn to the evaporation end 11, thereby obtaining a better heat dissipation effect.

The tube part 2 of the liquid-cooled tube 100 has a tube wall thickness of 0.06 to 0.2mm, preferably 0.1 mm.

The liquid cooling pipe 100 includes a pipe portion 2, and the pipe portion 2 includes a first wall portion 22 having a flat plate shape, a second wall portion 21 arranged in parallel with the first wall portion 22, a first connecting end 23 connecting one end of the first wall portion 22 and one end of the second wall portion 21 and having an arc shape, and a second connecting end 24 connecting the other end of the first wall portion 22 and the other end of the second wall portion 21 and having an arc shape. The core structure 3 is fixed to the first wall portion 22, a gap 5 being formed between the core structure 3 and the second wall portion 21. In other embodiments, the second wall portion 21 and the core structure 3 may also be arranged in contact.

In the present embodiment, the pipe portion 2 has a playground runway shape. In other embodiments, the shape of the tube 2 may be other shapes, and is not limited herein.

It will be apparent to those skilled in the art that various modifications and variations can be made to the above-described exemplary embodiments of the present invention without departing from the spirit and scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
