The utility model discloses an efficient radiator for aluminum extruded sunflower steam chamber, which comprises an upper end cover and a lower end cover. An aluminum alloy shell is arranged between the upper end cover and the lower end cover. A hollow steam passage is arranged in the middle of the aluminum alloy shell, and the inner wall of the hollow steam passage is uniformly provided with a tooth-shaped groove, and the inner part of the hollow steam passage is uniformly provided with copper powder. A column capillary channel is provided with a copper mesh capillary channel on the outer side of the mesoporous steam pipeline, a copper powder capillary layer on the upper end of the lower end cover and a circular hole on the upper end of the upper end cover. The radiator obtained by the utility model can rapidly diffuse the heat from the bottom to the fin surface through the steam chamber, so that the temperature distribution of the whole radiator is uniform, especially the temperature distribution on the fin surface is more uniform than that of other welded aluminum radiators, the heat exchange efficiency of the fin is greatly improved, and the integral forming design is compared with the existing ones. The structure cost of the sunflower extruded by copper hot column and aluminum can be reduced by at least 30%, and the manufacturing process can be reduced by more than five times.

一种铝挤太阳花蒸气腔高效散热器
本技术涉及散热器
,具体是一种铝挤太阳花蒸气腔高效散热器。
技术介绍
热柱太阳花散热器,工作原理是相变传热,其结构是在封闭的真空金属管内装置毛细吸液芯及液体工质,当热量从热柱底部传入热柱内部,液体工质吸热变成气体蒸发,并快速向管体冷凝端转移,在冷凝端释放热量后凝结成液体,沿吸液芯返回加热端,由此不断循环,大量的热量被迅速带走,然后再将热量传导到外围太阳花的鳍片上,再通过风扇将热量带走。现有的热柱太阳花散热器,是由多个单体热柱装配而成,然而单体热柱因制造工序复杂(近20个工序)造成成本高昂,现售价在20~30RMB之间,同时热柱和太阳花是两个零件,需先通过对两个零件的精密加工(对热柱外圆进行研磨或精车销,对太阳花内孔进行精密镗孔),造成两个零件的后工序加工成本很高(平均每个零件的加工费在1RMB左右),此外,两个零件在装配过程中(需进行紧配热塞工序)会造成约0.5%~1%的不良率。
