Embodiment
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is to a preferred embodiment that Figure 3 shows that heat-pipe radiating apparatus of the present invention.This heat-pipe radiating apparatus comprises the radiator 40 that is arranged on circuit board 10 sides, a heat pipe 21 and this heat pipe 21 is fixed on a heat pipe fixture 20 on this circuit board 10.This heat pipe 21 is a flat hot pipe, is the L type substantially, and it comprises an evaporation ends 211 and a condensation end 212.The condensation end 212 of this heat pipe 21 is fixedlyed connected with radiator 40, and the heat transferred radiator 40 that evaporation ends 211 is absorbed.The evaporation ends 211 of this heat pipe 21 carries out heat exchange by the heat-generating electronic elements 11 on this heat pipe fixture 20 and the circuit board 10, and by being fixed on the circuit board 10 with this heat pipe fixture 20.
This heat pipe fixture 20 comprises a plate 22 and a shell fragment 23.This plate 22 contact with electronic component 11 and be used to accommodate, the fixing evaporation ends 211 of heat pipe; This shell fragment 23 is releasably attached on this plate 22, and this plate 22 can be fixed on the heat-generating electronic elements 11.Below be described further at the concrete structure of this heat pipe fixture 20:
This shell fragment 23 is elongate, comprises that a pressure section 231, two connecting portions 232, each connecting portion 232 of extending to form to two ends from this pressure section 231 bend two locking parts 233 that extend to form in the end.These pressure section 231 horizontal-extendings, width is successively decreased to two ends by the centre, forms on this pressure section 231 shell fragment 23 is fixed on two lock holes 2310 on the plate 22.Two connecting portions 232 are upturned slightly with respect to pressure section 231, make whole shell fragment 23 form the high structure in low two ends, a centre.Two locking parts 233 are that incorgruous level bending extends to form to both sides again from the downward earlier bending in the end of connecting portion 232, respectively form a through hole 2330 in the end of two locking parts 233.The structure that whole shell fragment 23 is centrosymmetric.
Please be simultaneously with reference to Fig. 4, this plate 22 is one-body molded, and it has the contact plate 221 that contacts with heat-generating electronic elements 11.This contact plate 221 roughly is square, upwards bending extends to form two protruded stigmas 222 from the both sides of this contact plate 221, the free end of each protruded stigma 222 has a neck 2220, the external diameter of this neck 2220 is less than the aperture of the lock hole on the shell fragment 23 2310, and the length of the neck 2220 of this protruded stigma 222 is greater than the thickness of shell fragment 23, so that this shell fragment 23 can easy on and off after being enclosed within on the protruded stigma 222 activity, between shell fragment 23 and plate 22, holding the heat pipe of various outer diameter, thus the lifting versatility.Especially, can be by shell fragment 23 connect along the top slip of touch panel 221 and the strain of locking part 233, can realize the aliging of through hole 14,15 on through hole 2330 and the circuit board 10 easily, thus the further versatility of lifting device.This protruded stigma 222 forms two outwards outstanding projections 2221 in both sides, the top punching press of neck 2220, for convenient shell fragment 23 is assembled on the protruded stigma 222, two projections, 2221 outer surfaces on each protruded stigma 222 can be done camber, as circular arc, and ultimate range is slightly larger than on the shell fragment 23 aperture of corresponding lock hole 2310 between two projections, 2221 outer surfaces on each protruded stigma 222.This plate 22 is generally made with the copper or the aluminium of good heat conductivity, and shell fragment 23 is made of a steel, utilize steel than aluminium or the hard principle of copper, need only during assembling the lock hole on the shell fragment 23 2310 is aimed at corresponding protruded stigma 222 on the plates 22, press down and can easily shell fragment 23 be fixed on the plate 22 with finger, easy and simple to handle.Certainly, plate 22 also can be made with the material of other good heat conductivity, and also available other material of shell fragment 23 is made.This plate 22 forms protruded stigma 222 on contact plate 221 the outside horizontal-extending of two opposite side forms two extensions 223, and the width of this extension 223 is identical with the width of heat pipe 21, to carry the evaporation ends 211 of heat pipe 21 with contact plate 221.This two protruded stigma 222 is positioned at each side of two extensions 223 just, and near its corresponding extension 223, just heat pipe 21 is positioned between two protruded stigmas 222.
During assembling, plate 22 is placed on the heat-generating electronic elements 11, the condensation end 212 of heat pipe 21 is contained in the groove (figure is mark not) that forms on the radiator 40, its evaporation ends 211 places on the contact plate 221 of plate 22, lock hole on the shell fragment 23 2310 is aimed at the protruded stigma 222 of plate 22, make lock hole 2310 be pressed through the projection 2221 of these protruded stigma 222 ends with the downward application of force of finger, be enclosed within the outer peripheral face of neck 2220.In addition, because the ultimate range between these two projection 2221 outer surfaces is greater than the aperture of lock hole 2310, and neck 2220 external diameters of two protruded stigmas 222 are less than the aperture of lock hole 2310, so what this shell fragment 23 can the easy on and off activity is nested with on the neck 2220 of protruded stigma 222, to hold the heat pipe of various outer diameter between shell fragment 23 and plate 22.Utilizing retaining elements 50 such as screw or rivet to pass through hole 14,15 corresponding on through hole 2330 and the circuit board 10 is fixed on shell fragment 23 on this circuit board 10, since the setting of the neck 2220 of protruded stigma 222, heat pipe 21 take place through hole 2330 on the micro-strain shell fragments 23 on also can alignment circuit plate 10 through hole 14,15 and reach fixing.At this moment, because the high shape in low two ends in the middle of the shell fragment 23, make two connecting portions 232 that elastic deformations take place downwards and produce downward power, plate 22 can be pressed on the heat-generating electronic elements 11 securely, make pressure section 231 replace on heat pipe 21 and heat pipe 21 is fixed on the contact plate 221.In the process of retaining element 50 fastenings, the pressure section 231 of shell fragment 23 is pressed on the heat pipe 21, and plate 22 is pressed on the heat-generating electronic elements 11 simultaneously.For the heat that increases heat pipe 21 and contact plate 221 passes effect, can contact by soldering or heat-conducting cream between the two.
For another heat-generating electronic elements 12 to circuit board 10 bottom surfaces dispels the heat and the intensity of intensifier circuit plate 10, one substrate 30 further is set for 10 times at circuit board.
In the present embodiment, shell fragment 23 has adopted two identical fixtures 50 with substrate 30, reduces assembly program, saves cost.Certainly, also can respectively shell fragment 23 and substrate 30 be fixed on and reach fully contacting of heat-generating electronic elements 11,12 separately on the circuit board 10.
During work, the heat that heat-generating electronic elements 11 produces is delivered to the evaporation ends 211 of heat pipe 21 via the contact plate 221 of plate 22, be evaporated to condensation end 212 via the working medias in the heat pipe 21, this heat more further the radiator 40 of the condensation end 212 by connecting heat pipe 21 air-flow that cooperates fans (figure marks) to blow out heat is dispersed into the external world fast.The heat that heat-generating electronic elements 12 produces directly is dispersed in the air via substrate 30.
