Description

可增加散热面积的热管式散热鳍片 Heatpipe fins for increased cooling area

技术领域technical field

本实用新型属于一种散热鳍片,尤指一种可增加散热面积的热管式散热鳍片,其具有弯曲部位而较平坦部位具有较多的表面积以便增进与空气的热交换效率。The utility model belongs to a heat dissipation fin, in particular to a heat pipe type heat dissipation fin which can increase the heat dissipation area. It has a curved part and a relatively flat part has more surface area so as to improve the heat exchange efficiency with air.

背景技术Background technique

由于半导体技术突飞猛进,目前的计算机处理器芯片不但运算频率节节攀升,内部的晶体管数量也以倍数成长,导致芯片发热功率不断飙升,因此在芯片上设置散热器早已是习以为常的散热做法。Due to the rapid advancement of semiconductor technology, the current computer processor chips not only increase the operating frequency, but also increase the number of internal transistors by multiples, resulting in a continuous increase in the heating power of the chip. Therefore, it has long been a common practice to install a heat sink on the chip.

现有的散热器有空冷与水冷两种大类,前者靠空气对流来进行散热,是目前最为普及的散热器种类。又,空冷散热器之中又有一种能增进热传导效率的热管式散热鳍片,即是以复数热管贯穿复数散热鳍片,透过热管内部的流体的毛细作用,能令热量迅速延热管传递到各散热鳍片上,以增进散热效率。There are two types of existing radiators: air-cooled and water-cooled. The former relies on air convection to dissipate heat, and is currently the most popular type of radiator. In addition, there is another kind of heat pipe fin in the air-cooled radiator, which can improve the heat conduction efficiency, that is, a plurality of heat pipes run through the plurality of fins, and through the capillary action of the fluid inside the heat pipe, the heat can be quickly transferred to the heat pipe. Each cooling fin to improve heat dissipation efficiency.

上述的热管式散热器之中,由于热管的热传导效率极高,因此散热瓶颈往往在于散热鳍片与空气的热交换效率,而与空气的热交换效率往往取决于散热鳍片的表面积大小。但,目前的散热鳍片皆为薄片式而无任何新颖的设计来增进热交换效率。Among the above-mentioned heat pipe radiators, due to the extremely high heat conduction efficiency of the heat pipe, the heat dissipation bottleneck often lies in the heat exchange efficiency between the heat dissipation fins and the air, and the heat exchange efficiency with the air often depends on the surface area of the heat dissipation fins. However, the current heat dissipation fins are all thin-sheet type without any novel design to improve heat exchange efficiency.
