Description

散热装置
技术领域
本实用新型涉及一种散热装置。
背景技术
随着计算机技术的不断发展,电子元件(尤其是中央处理器)运行频率和速度不断提升。高频高速也使得电子元件产生的热量随之增多,使得其温度不断升高,影响运行时的性能,为确保电子元件正常运行,必须及时排出电子元件所产生的大量热量。
通常业界是正对中央处理器安装一方形的散热器进行散热。单纯金属制成的散热器一般包括一平滑的底座,供贴设在中央处理器表面以吸收其产生的热量,再经底座向上传至散热鳍片进行散热。随着中央处理器的体积越来越小,运行速度越来越快,其发热更集中,传统的散热器已不能很好的满足散热要求。为此,业界采用热管传导热量的散热装置越来越多。通常热管的一端容置在散热器的底座内,另一端穿过这些散热鳍片。电子元件产生的热量传递到散热器的底座,再通过热管传递至其上部的散热鳍片上,最后通过散热鳍片将热量散发到周围的空气中。有的甚至进一步在该散热器的顶部加装一风扇,以达到冷却中央处理器的目的。然而,仅在正对中央处理器的一侧设置散热器、热管及风扇仍不能很好的散发中央处理器产生的热量。
发明内容
鉴于以上内容,有必要提供一种提高电路板的电子元件散热效率的散热装置。
一种散热装置,用于散发一电路板的电子元件所产生的热量,该散热装置包括一与该电子元件接触的基板、一设置于该基板的第一散热鳍片组及至少一设置在该基板与该第一散热鳍片组之间的第一热管,该基板上还设置一邻接该第一散热鳍片组且位于该电子元件一侧的第二散热鳍片组,该第一热管并延伸至该基板与该第二散热鳍片组之间。
该电路板的电子元件产生热量不仅通过与其正对的第一散热鳍片组散热,还通过该第一热管将热传递至该第二散热鳍片组进行散热,提高了散热效率。
