热管散热器

 镶热管 镶铜管散热器

当空间受限或者通风不畅时，镶热管或镶铜管散热就成为一个很好选择。

热管能水平放置来解决空间高度受限而达到散热需要。通常由于有障碍物阻挡空气不能自由流动来冷却设备，我们用热管将蒸发器与远端的被阻塞通风的冷凝器连接起来以达到冷却效果。

铜有更好的热导性，但当铝质底座不能承受其重量时，用较轻的热管来代替铜板也可以起到所需要的散热效果。热管也可以镶嵌在铜质底座里以减小质量来达到散热效果。

使用热管后，不需使用电扇来散热并能以低转速来运转系统，这样带来的直接好处是能提供系统工作的稳定性和降低维护费用。相对传统的散热解决方案，在低速空气流动情况下用热管也能提高散热效果。

Transport designs can be useful where space is constrained or airflow is not available directly over the device requiring cooling. Examples of application characteristics where transport heat pipes solutions may solve design issues include:

Limited height or space—Heat pipes can spread the cooling solution volume horizontally rather than vertically to achieve the desired thermal performance.

Obstructed airflow—Obstructions in the chassis may leave insufficient airflow over the device to be cooled. Connecting an evaporator to a remote condenser using a heat pipe allows the condenser to be placed in an area of unobstructed airflow to provide the necessary cooling.

Heat pipes can be added to an aluminum base when the use of higher thermally conductive metal like copper cannot be tolerated due to weight. Heat pipes can also be embedded in copper bases to increase spreading without adding mass to the solution.

Elimination of fans or operating them at lower RPMs can increase system reliability and lower maintenance costs. Passive solutions using heat pipes may increase performance at lower airflow than with conventional thermal solutions.
