A wireless communication system includes an antenna, a receiving module, a power source, and a power control hub. The power control hub includes an amplifier having a first end coupled to the receiving module and a second end coupled to the power source. The amplifier generates a first output signal based on a control signal of the receiving module. The power control hub includes a rectifier having a first end coupled to the output end of the amplifier and a second end coupled to the power source. The rectifier generates a second output signal based on the first output signal. The power control hub also includes a switch. A first and a second end of the switch are electrically connected or disconnected based on the second output signal received at a control end of the switch.

A heat pipe (20) includes a pipe (22), a plurality of grooves (24), a hydrophilic layer (26), and a liquid operating fluid (28). The pipe includes an evaporator section (30) and an opposite condenser section (32). The grooves are formed on an inside wall (222) of the pipe. The hydrophilic layer is coated on the grooves. The operating fluid is located in the evaporator section. The operating fluid absorbs heat and is vaporized. The vapor is diffused to the condenser section and releases heat, thereby being transformed back into liquid. The liquid is adsorbed by the hydrophilic layer and is reflowed. This adsorption reduces or even avoids a shear force at an interface of the diffusing vapor and the reflowing liquid. Thus, the cyclical speed of the operating fluid is quickened, enhancing the thermal operating efficiency of the heat pipe.

A thermal assembly includes a heat source (10), a heat sink (50), a thermal interface material (30) and a porous membrane (20). The heat sink is over the heat source. The thermal interface material is enclosed with the porous membrane, with both being between the heat source and the heat sink. The porous membrane has a number of holes (23a) in which a number of carbon nanotubes (28) are provided. A method for fabricating the thermal assembly includes the following steps. The heat source having a surface is provided, wherein the surface defines a central part. The thermal interface material is coated onto the central part of the surface of the heat source. The thermal interface material is enclosed with the porous membrane, the porous membrane having the holes in which the carbon nanotubes are provided. The heat sink is attached to the heat source.
