First embodiment

In the prior art, the terminal comprises a heat dissipation air pipe and a fan arranged at an air outlet of the heat dissipation air pipe, the fan sucks cold air from the outside of the terminal through an air inlet of the heat dissipation air pipe, the cold air flows through the heat dissipation air pipe and is subjected to heat transfer with heat generated by operation of a terminal device near the heat dissipation air pipe, and then the cold air is discharged from a mute fan through an air outlet of the heat dissipation air pipe to dissipate heat. Because the heat conduction coefficient of the heat dissipation air pipe is low, the heat exchange efficiency of cold air is not high, the heat accumulation in the terminal is caused, the phenomenon of scalding hands easily occurs, the user experience is reduced, in addition, the abnormal operation of devices is easily caused by the heat accumulation, and the user experience is further reduced. In order to solve the above technical problem, the present embodiment provides a terminal heat dissipation air duct, referring to fig. 4, where fig. 4 is a schematic structural diagram of the terminal heat dissipation air duct provided in the present embodiment, and the terminal heat dissipation air duct 40 includes: a duct body 401 and a heat conductive layer 402 disposed on a surface of the duct body 401.

It should be understood that, in the present embodiment, the duct body 401 includes a cavity to form a heat dissipation duct. The duct body 401 includes an air inlet and an air outlet, and cool air outside the terminal enters through the air inlet and is discharged through the air outlet. In this embodiment, the air inlet of the duct body 401 may serve as an interface between the heat dissipation air duct and the air outside the terminal, and in order to enable the air inlet to exchange air with the outside of the terminal, the air inlet may be disposed on the terminal housing, for example, may be disposed on the terminal middle frame, and of course, may be disposed at another position (for example, a terminal rear cover).

Wherein, the pipe body 401 may be made of a metal material, for example, may be made of an aluminum alloy; of course, the pipe body 401 may also be made of a non-metallic material.

In this embodiment, the heat conducting layer 402 is made of a material with high thermal conductivity to increase the thermal conductivity of the terminal heat dissipating air duct 40 and increase the terminal heat dissipating performance.

Or, in order to further improve the heat dissipation performance of the heat dissipation pipeline, the surface of the terminal heat dissipation air duct 40 may be a roughened surface (i.e., a non-smooth surface), and since the roughened surface is larger than the smooth surface, the surface area of the heat dissipation is increased, the contact area between the air and the heat dissipation pipeline is increased, and the heat dissipation performance is improved. The outer surface of the terminal heat dissipation air duct 40 may be a roughened surface, or the inner surface may be a roughened surface, and of course, both the outer surface and the inner surface of the terminal heat dissipation air duct 40 may be roughened surfaces.

The high thermal conductivity material is sprayed on the surface of the pipe body 401 at a high speed by using compressed gas to form the heat conductive layer 402 based on a cold melting and spraying technology, so that the surface of the pipe body 401 is bonded with the heat conductive layer 402, and in other embodiments, the surface of the pipe body 401 may be bonded with the heat conductive layer 402 in other manners.

It should be understood that the tube body 401 includes an inner surface and an outer surface, and in this embodiment the heat conductive layer 402 is disposed on the outer surface of the tube body 401, although in other embodiments the heat conductive layer 402 may be disposed on the inner surface of the tube body 401, or both the inner and outer surfaces.
