surface again Open in portion 6112, and the space size of the airflow in the enlarged portion 6112 can be made to produce change, therefore, When air-flow flows through enlarged portion 6112 along the radiating convex portion 6142 of the conductive force wall 614, even if The flow velocity and pressure for obtaining air-flow constantly produce change, and can destroy the radiating convex portion of the conductive force wall 614 The boundary layer on 6142 surfaces, makes air-flow be easy to the heat band of the radiating convex portion 6142 of the conductive force wall 614 From, and electronic component is maintained at normal working temperature, to prevent electronic component from damaging, and then reach significantly The Practical Benefit of improving radiating effect and lifting electronic component service life.

Refer to shown in Figure 17, Figure 18, Figure 19, Figure 20, the fourth embodiment of heat abstractor of the present invention 70, It includes body 71, conducting element 72 and blower 73；The body 71 is provided with tool throwing part and at least in being The air channel 711 of one enlarged portion, and it is provided with an at least conductive force wall；In the present embodiment, the body 71 sets There is a general C-shaped tube wall 712 of section configuration, and two ora terminalis in the front side of tube wall 712 are respectively equipped with one and prolong Wall 713 is stretched, and in throwing part 7111 is provided with the tube wall 712 of the body 71, between two wall extension 713 then It is provided with the enlarged portion 7112 communicated with the throwing part 7111, and the throwing part 7111 by the body 71 and expansion Portion 7112 forms the air channel 711, wherein, inclined outer of two wall extensions 713 of the body 71, make this two There is angle theta, the angle theta is 60 °~90 ° between wall extension 713；Also in the wall extension of tube wall 712 and two 713 outside is arranged with that section is general rectangular and outer tube 715 of tool conductive force wall 714, and this two is prolonged Two side positions that wall 713 is connected to the conductive force wall 714 are stretched, the outside of the conductive force wall 714 is provided with For the assembled portion 7141 of connection installing electronic component, inner side is then provided with the enlarged portion for convexedly stretching in the air channel 711 Radiating convex portion 7142 in 7112, and it is respectively equipped with circular arc in the apical margin of the radiating convex portion 7142 and two lateral margins Section, makes the radiating convex portion 7142 that the enlarged portion in the air channel 711 of the body 71 is convexedly stretched in smooth curved surface In 7112；The body 71 throwing part 7111 in be arranged be fixed with to should conductive force wall 714 group The conducting element 72 in dress portion 7141, the conducting element 72 is provided with a body of rod 721, and in the anchor ring of the body of rod 721 Helical blade 722 is provided with, the outer rim of the helical blade 722 can be connected in the tube wall 712 of the body 71 The apical margin of radiating convex portion 7142 of wall and the conductive force wall 714, or with the tube wall 712 of the body 71 in Wall and and the apical margin of radiating convex portion 7142 of the conductive force wall 714 there is appropriate gap；In the present embodiment In, the outer rim of helical blade 722 of the conducting element 72 is connected to the internal face of tube wall 712 of the body 71 and is somebody's turn to do The apical margin of radiating convex portion 7142 of conductive force wall 714, and there is preferably water conservancy diversion effect；Also in the body 71 Air channel 711 connect be provided with can be fan or air blower blower 73, with the air channel 711 of the body 71 Interior conveying gas, makes to produce air-flow in the air channel 711 of the body 71；In the present embodiment, the blower 73 Connected between the air channel 711 of the body 71 and be provided with a connecting pipe 731, the gas of the blower 73 conveying is to pass through It is input into the air channel 711 of the body 71 by the communicating pipe 731, and makes to be produced in the air channel 711 of the body 71 Anger stream, and the air-flow in the air channel 711 of the body 71 is guided with the helical blade 722 of the conducting element 72, Spirally path is circulated in the throwing part 7111 and enlarged portion 7112 in the air channel 711 to make the air-flow；Also A dividing plate 716 is provided with the outer tube 715, and is offered on the dividing plate 716 to should body 71 The notch 717 of the shape of air channel 711, and the blower 73 is conveyed gas concentration and pass into the body 71 In air channel 711；In this way, being conducted when the heat produced by electronic component to the conductive force wall 714 of the body 71 Radiating convex portion 7142 when, i.e., with the blower 73 in the body 71 air channel 711 in conveying gas, make Air-flow is produced in the air channel 711 of the body 71, and the pipe is guided with the helical blade 722 of the conducting element 72 Air-flow in the air channel 711 of body 71, spirally path circulates in the throwing part in the air channel 711 to make the air-flow 7111 and enlarged portion 7112 in, and utilize the spiral helicine airflow by the conductive force wall 714 dissipate Hot convex portion 7142, and the heat of the radiating convex portion 7142 of the conductive force wall 714 is taken away, due to the air channel 711 enlarged portion 7112 is that the free air space for making air-flow expands, and the conductive force wall 714 radiating convex portion 7142 are convexedly stretched in the enlarged portion 7112 with smooth curved surface again, and can make the gas in the enlarged portion 7112 The space size of circulation produces change, therefore, when air-flow is along the radiating convex portion of the conductive force wall 714 7142 when flowing through enlarged portion 7112, though air-flow flow velocity and pressure constantly produce change, and can The boundary layer on the radiating surface of convex portion 7142 of the conductive force wall 714 is destroyed, makes air-flow be easy to make the heat conduction Taken away with the heat of the radiating convex portion 7142 of wall 714, and electronic component is maintained at normal working temperature, with Prevent electronic component from damaging, and then reach the reality that radiating effect and lifting electronic component service life is substantially improved Use benefit.

It is described above to be merely exemplary for the purpose of the present invention, and nonrestrictive, ordinary skill people Member understand, in the case where the spirit and scope that claim is limited are not departed from, can many modifications may be made, Change is equivalent, but falls within protection scope of the present invention.
