Abstract: In this paper，a new-style plate heat pipe radiator is proposed，together with an experiment system，to investigate its thermal performance under different quantity，position and airflow rate. The experimental results indicated that this plate heat pipe radiator has wonderful heat dissipating capacity and small overall thermal resistance. With the increase of heat sources number，overall thermal resistance was reduced，the maximum heat transport capacity and heat dissipation capacity were improved significantly. When the heat source temperature is below 65 ℃，the heat transferred can still reach nearly 400 W，which is very suitable for the heat dissipation of multi-heat spots electronic components with high heat flux.

摘要： 提出了一种新型平板热管散热器，通过建立实验平台，研究了它在不同热源数量、不同的热源位置以及不同风速下的传热性能。实验表明，这种平板热管散热器散热量大，总热阻小，而且在热源数量增加时，最大传热量和最大散热能力增大，总热阻减小。在规定热源温度65 ℃以下时，其热传输量将近400 W，非常适合于高热流密度、多散热点的电子器件散热。
