Further, antenna holder 6 is one-body molded with conducting-heat elements 5.Adopt antenna holder 6 and conducting-heat elements 5 integrated manufacture crafts, both can realize the purpose of utilizing the antenna holder zone to dispel the heat more fully can also making that the process of making antenna holder is simple and easy to do, be convenient in existing factory streamline, produce.
Need to prove that this embodiment is applied widely, can be used for all have radio communication function and in the wireless terminal of antenna holder is arranged.
Embodiment two
The embodiment of the invention provides a kind of wireless terminal, and is as shown in Figure 1, and this wireless terminal comprises:
The antenna holder 6 in the no circuit zone 1 of circuit board and the end that is wrapped in said circuit board, said antenna holder 6 is provided with conducting-heat elements 5, and said conducting-heat elements 5 is connected with the circuit zone 2 that has of said circuit board.
Need to prove; Wireless terminal antenna is main with the built-in aerial that does not influence the wireless terminal profile at present, and the wireless terminal built-in aerial designs, and uses FPC to make; It is inboard to be attached to the wireless terminal shell, links with miscellaneous part with thimble and the antenna holder 6 that plays a part to support.Because setting up of antenna all is as far as possible away from ground and building; In the time of the approaching reference of antenna ground; Most of energy (being wireless signal) will concentrate on antenna and with reference to launching smoothly between the ground, so antenna emission needs the space of " opening as far as possible ".And the wireless terminal circuit board is exactly the reference ground of wireless terminal antenna, lets antenna away from other circuit of wireless terminal, is the key that improves the wireless terminal antenna emission effciency.So the antenna holder 6 of supporting antenna is wrapped in the no circuit zone 1 of the end of said circuit board.
Further; The a lot of devices of the circuit board of wireless terminal such as mobile phone, GPS top all is covered with the layer of metal radome; Like the radome among Fig. 13, the circuit on the protective circuit plate does not receive the extraneous static or the interference of external electromagnetic field, has guaranteed that the wireless terminal internal circuit can operate as normal.
In the present embodiment; Circuit board the circuit regional work is arranged the time heat that sends directly be delivered to the antenna holder that temperature is lower, volume is bigger via conducting-heat elements with the form of heat transmission via conducting-heat elements 5 or through radome; Be passed to external environment via antenna holder through the wireless terminal shell again; Played and reduced the wireless terminal internal temperature, prevent that the temperature that the circuit zone is arranged of circuit board is too high and influence the reliability of wireless terminal and the effect in useful life, reduced the maximum temperature of wireless terminal shell simultaneously effectively.
In the present embodiment, the material of antenna holder 6 is that (conductive coefficient is meant under the steady heat transfer condition conductive coefficient, the material that 1m is thick greater than 2W/mK; The temperature difference of both side surface is 1K; In 1 second, through the heat that 1 square metre of area transmits, unit is watt/Mi Du; Be W/mK) organic composite material (such as in plastics, adding the higher metal dust of conductive coefficient, like alundum (Al particle, aluminum nitride particle etc.; Or in plastics, add other filler that improves material property etc.); The material of conducting-heat elements 5 is the organic composite material of conductive coefficient greater than 2W/mK; Such as the composite material of pottery, modification (such as in plastics, adding the higher metal dust of conductive coefficient, like alundum (Al particle, aluminum nitride particle etc.; Or in plastics, add other filler that improves material property etc.).
Further, antenna holder 6 is one-body molded with conducting-heat elements 5.Adopt antenna holder 6 and conducting-heat elements 5 integrated manufacture crafts, both can realize the purpose of utilizing the antenna holder zone to dispel the heat more fully can also making that the process of making antenna holder is simple and easy to do, be convenient in existing factory streamline, produce.
Further; Though in the process of fabrication and processing; The surface of circuit board, radome 3 and conducting-heat elements 5 done as far as possible smooth; But because the restriction of manufacture craft and material, can there be can not realize ideal smooth smooth under the state of imperceptible rough space in this three surface.So conducting-heat elements 5 and circuit board circuit zone 2 is arranged and after radome 3 contacts respectively; Real contact area between them probably has only 10% of conducting-heat elements 5 surface areas, and all the other are the air gap, because the air conductive coefficient has only 0.025W/mK; It is the non-conductor of heat; To cause the contact heat resistance that 5 of circuit zone 2, radome 3 and conducting-heat elements are arranged of circuit board very big, seriously hinder the conduction of heat, and finally cause the usefulness of conducting-heat elements 5 low; When circuit board have circuit zone 2 and conducting-heat elements 5 joints that electronic device is arranged the time, the usefulness of conducting-heat elements 5 can be lower.Fill full these spaces so use heat-conducting filler with high-termal conductivity; Get rid of the air in the space; Have circuit zone 2, radome 3 and 5 of conducting-heat elements to set up effective heat to pass to passage at circuit board; Can strengthen the heat conduction efficiency of conducting-heat elements 5 significantly, the effect of conducting-heat elements 5 is fully played.
Further, the material of heat-conducting filler is the heat-conducting interface material of conductive coefficient greater than 2W/mK.
Need to prove that this embodiment is applied widely, can be used for all have radio communication function and in the wireless terminal of antenna holder is arranged.
The above; Be merely embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technical staff who is familiar with the present technique field is in the technical scope that the present invention discloses; Can expect easily changing or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of said claim.
