[embodiment]
The present invention is described in detail below in conjunction with drawings and Examples.
As Figure 1-3, heat-pipe radiator 2 of the present invention mainly comprises: a plurality of have endothermic section 211 and with the pedestal 22 of the heat pipe 21 of the crooked radiating parts 212 that are connected in endothermic section 211, support heat pipe 21 and be located in a plurality of fin 23 on the radiating part 212 of heat pipe 21.In the present embodiment, pedestal 22 is the tabular fixed block, and the bottom surface of pedestal 22 is provided with a groove 221 that can hold the endothermic section 211 of a plurality of heat pipes 21.In the present embodiment, groove 221 is formed by two trenched side-walls, 224,225 definition of space, and groove 221 inside have the arc groove face 222 that at least two juts 223 form at interval, and the height of jut 223 is less than the height of trenched side-wall 224,225.Form inwardly outstanding holding section 226,227 on the trenched side-wall 224,225.The endothermic section 211 of heat pipe 21 is arranged side by side in groove 221.Specifically, the endothermic section 211 of heat pipe 21 part respectively is contained in the arc groove face 222, and part exposes to the opening of groove 221, and is extruded being clamped in the groove 221 of being out of shape and therefore bearing against mutually.The exposed parts of the endothermic section 211 of heat pipe 21 forms equal with the bottom surface of pedestal 22 and as the compressive plane 214 of heat-absorbent surface.Holding section 226,227 engagings further strengthen fixed effect thus near the lateral surface of the endothermic section 211 of the heat pipe 21 of trenched side-wall 224,225.In the present embodiment, after the endothermic section 211 of heat pipe 21 was extruded distortion and then bears against in the ground clamping groove 221 mutually, the adjacent side of the endothermic section 211 of heat pipe 21 to small part contacted and bears against mutually, and the edge of the compressive plane 214 of heat pipe is in contact with one another simultaneously.In the present invention, " a plurality of " expression " at least two ".
In the present embodiment, groove 221 horizontal expansion and leap pedestal 22 on the bottom surface of pedestal 22.And, between groove 221 and the endothermic section 211 heat-conducting medium can be set further.Fin 23 is made with aluminium, copper or other thermal diffusivity good metal material, is provided with a plurality of perforation thereon.Heat pipe 21 can be L type, U type or has the heat pipe of other curved shape, and its inside has capillary structure and hydraulic fluid, and the outside is formed with endothermic section 211 and radiating part 212.In addition, radiator 2 can also adopt other appropriate configuration except that can be above-mentioned kenel.Because endothermic section 211 press nip are in groove 221, the manufacturing process of radiator 2 is simpler, and fixed effect is better.
In the process of extruding endothermic section 211, should make the compressive plane of endothermic section 211 equal with the base plane of pedestal 22.Like this with radiator 2 and electronic component (not shown) when fixing, the compressive plane of endothermic section 211 and the pyrotoxin of electronic component be surperficial directly to be contacted and as heat-absorbent surface, increases the heat-conducting effect and the heat dispersion of radiator thus.Between endothermic section 211 and groove 221, can also heat-conducting medium be set further, endothermic section 211 is fully contacted with pedestal 22 by heat-conducting medium, further promote heat-conducting effect thus.In addition,, can increase heating surface area, improve heat-conducting effect because a plurality of endothermic sections 211 are arranged side by side in a groove.
Introduce manufacture method one preferred embodiment of heat-pipe radiator of the present invention below, in the present embodiment, at first, the pedestal 22 that at least two heat pipes 21 is provided and supports heat pipe 21.Heat pipe 21 has endothermic section 211 and the radiating parts 212 that are connected with endothermic section 211 bendings, and a groove 221 is set on the bottom surface of pedestal 22.Groove 221 is formed by two trenched side-walls, 224,225 definition of space, and groove 221 inside have at least two arc groove faces 222 that formed at interval by jut 223.The height of jut 223 is less than the height of trenched side-wall 224,225.Form inwardly outstanding holding section 226,227 on the trenched side-wall 224,225.
Then, the endothermic section 211 of at least two heat pipes 21 is arranged side by side in groove 221, and the endothermic section 211 of heat pipe 21 respectively part be contained in the arc groove face 222, part exposes to the opening of groove 221.
Therefore at last, the exposed parts of the endothermic section 211 of extruding heat pipe 21 is so that endothermic section 211 deforms and be clamped in the groove 221 mutually with bearing against.In extrusion process, the adjacent side of the endothermic section 211 of heat pipe 21 to small part contacts and bears against mutually, holding section 226,227 engaging is near the lateral surface of 211 ones of the heat absorptions of the heat pipe 21 of trenched side-wall 224,225, so that being clamped in the groove 221 of bearing against mutually of the endothermic section 211 of heat pipe 21.
Simultaneously, the exposed parts of endothermic section 211 forms equal with the bottom surface of pedestal 22 and as the compressive plane 214 of heat-absorbent surface, and the edge of the compressive plane 214 of heat pipe 21 is in contact with one another.
In the above-described embodiments, only the present invention has been carried out exemplary description, but those skilled in the art can carry out various modifications to the present invention after reading present patent application under the situation that does not break away from the spirit and scope of the present invention.
