Background technology
Generally speaking, mobile communication terminal is to carry telephone set easy, that can carry out telephone relation in moving with wireless mode.
Therefore, as shown in Figure 1, various radio communications electronic components 3 are installed on the printed circuit board (PCB) 2 of general mobile communication terminal in terminal enclosure 1, electrical load heat takes place because of starting in electronic components 3 when mobile communication terminal uses, the heat of Chan Shenging passes to terminal enclosure 1 and is discharged into the outside like this. still, user's handheld terminal shell 1 during use causes inner heat to discharge smoothly by terminal enclosure 1 surface, and therefore the problem that electronic components 3 damages and phone system are made mistakes takes place.
Summary of the invention
The object of the present invention is to provide a kind ofly have rapidly, successfully the heat release of terminal enclosure inside to outside mobile communication terminal heat abstractor with cooling and double as antenna of antenna function. it is characterized in that: printed circuit board (PCB) is installed in terminal enclosure, a plurality of electronic components that comprise the transceiver signal processing part are installed on the printed circuit board (PCB); Metal tube, its upper end is exposed to the terminal enclosure outside, and the lower end is installed in the terminal enclosure; Earth connection, metal tube is connected with transceiver signal processing part forming circuit on the printed circuit board (PCB). in addition, the cooling pin of a plurality of projectioies is installed on the exterior face of metal tube, with enlarge with printed circuit board (PCB) on the heat of electronic components " E " generation of installing and the area that extraneous air contacts.
The invention has the beneficial effects as follows injection in the heat conduction phenomenon of utilizing the metal tube that the lower end is installed in the terminal enclosure, the upper end is exposed to terminal enclosure and the above-mentioned metal tube refrigerant to flow phenomenon, the heat of terminal inner is discharged into the outside rapidly, in addition, above-mentioned metal tube is connected with transceiver signal processing part forming circuit, the performance antenna function.

Embodiment
2,3 couples of the present invention are described in detail with reference to the accompanying drawings.
Fig. 2 is the outside oblique view of mobile communication terminal of the present invention, and Fig. 3 is the inner section figure of mobile communication terminal of the present invention.
Shown in Fig. 2,3, printed circuit board (PCB) 140 is installed in the terminal enclosure 110, a plurality of electronic components " E " of the transceiver signal processing part 141 of the signal that comprises that processing and utilizing antenna (not marking among the figure) receives and sends are installed on the printed circuit board (PCB) 140, in this terminal enclosure 110, the present invention is made of following several sections: metal tube 120, the one end is exposed to terminal enclosure 110 outside certain-lengths, and the lower end is installed in the terminal enclosure 110; Refrigerant 130 is positioned at above-mentioned metal tube 120, utilizes the temperature difference causes flow phenomenon is flowed; Earth connection 142 makes above-mentioned metal tube 120 be connected with transceiver signal processing part 141 forming circuits on the printed circuit board (PCB) 140.
In addition, a plurality of cooling pins 121 protrude to be installed preferably on the exterior face of metal tube 120, enlarge with printed circuit board (PCB) 140 on the heat of electronic components " E " generation of installing and the area that extraneous air contacts.
And preferably install near the electronic components " E " that produce load heat metal tube 120 lower ends of installing in the terminal enclosure 110.
In addition, both allocations of printed circuit board (PCB) 140 are fixed in soft soldering in the two ends of earth connection 142, and it is connected with transceiver signal processing part 141 forming circuits with the specified location of metal tube 120 respectively.
With reference to the accompanying drawings 3, describe useful embodiment of the present invention in detail. when using mobile communication terminal 100, a plurality of electronic components " E " of installing on the printed circuit board (PCB) 140 produce electrical load heat. the load heat that produces by electronic components " E " like this, a part is delivered to terminal enclosure 110 and is discharged into the outside, behind metal tube 120 lower ends that all the other load heat are installed in passing to terminal enclosure 110, heat conduction phenomenon by metal is delivered to metal tube 120 upper ends that protrude from terminal enclosure 110 outsides, and be discharged in the outside atmosphere by the extraneous air that is contacted with above-mentioned metal tube 120 upper ends. at this moment, the cooling pin 121 of metal tube 120 has played the effect of enlarged metal pipe 120 endotherm areas and area of dissipation, therefore makes metal tube 120 can reduce the internal temperature of terminal enclosure 110 rapidly; Refrigerant 130 in the metal tube 120 to the upper end, makes the heat transferred of metal tube 120 lower ends heat be discharged into terminal enclosure 110 outsides with when flow phenomenon is flowed.
In addition, metal tube 120 detects outside electric wave signal, is delivered to transceiver signal processing part 141 by earth connection 142, and being transmitted into the outside by earth connection 142 from the electric wave signal that transceiver signal processing part 141 transmits, the performance antenna function.
