与个人计算机（PC）的广泛使用及其性能的快速增长相关的当前重要问题是降低在冷却系统风扇操作时产生的噪声水平。解决该问题的可能方式之一可以是在回路热管（LHP）的基础上创建无源或半无源系统，其中散热器是通过自然和/或强制空气对流冷却的外部散热器。本文介绍了这种系统的几种变体的开发和测试的结果，这些系统能够在22摄氏度的环境温度下消耗100 W的热源热界面上维持72- 78摄氏度的工作温度。它还表明，使用额外的主动冷却手段与LHP相结合，允许增加耗散热量的值高达180 W，并降低系统热阻高达0.29 ℃/W
The problem of current importance connected with a wide use of personal computers (PC) and a rapid growth of their performance is a decrease in the level of noise created at the operation of cooling system fans. One of the possible ways of solving this problem may be the creation of passive or semi-passive systems on the base of loop heat pipes (LHPs) in which the heat sink is an outer radiator cooled by way of natural and/or forced air convection. The paper presents the results of development and tests of several variants of such systems, which are capable of sustaining an operating temperature of 72-78degC on the heat source thermal interface which dissipates 100 W at an ambient temperature of 22 degC. It is also shown that the use of additional means of active cooling in combination with LHPs allows increasing the value of dissipated heat up to 180 W and decreasing the system thermal resistance up to 0.29degC/W
