摘要：为考察基于矩形平行细小槽道的压降及传热的综合性能，实验测试了去离子水流过三种不同截面尺寸的平行细小槽道热沉的流动与传热特性，槽道截面尺寸分别为1mm×1mm、0．5mm×1mm、0．5mm×1．2mm，表面热流密度为5．6—33．3W／cm2，工质流量为0．3～5L／min。实验测量了压降及对流换热系数随流量变化关系；综合分析了三种热沉的压降一温度随流量变化规律；得出了细小槽道热沉在给定流量范围内，表面温度为70~C时的极限热流密度。实验结果表明：随着流量增加，表面温度与压降呈相反变化趋势，存在一个最佳工况点，该工况点处的工质流量随热流密度增加而增大；文中所设计的热沉在工质流量为1．3—4．75L／min，表面温度控制在70℃时所能承受的极限热流密度为70W／cm2，此时压降约为170kPa。

摘要：这是关于机箱的八个疑问，你都知道答案吗？如果不能，请继续往下看你知道“38℃机箱”也有“真假李逵”吗？你知道“38℃机箱”有哪些散热死角吗？为什么“38℃机箱”一定要有侧板导风管？为什么TAC2.0机箱要取消侧板导风管？为什么TAC2.0机箱要增大散热网孔的面积7为什么TAC2.0机箱要提高安全温度？为什么集成主板的南北桥散热器越做越豪华？有没有想过,显卡的部分设计成本也许不该由你来买单呢？

摘要：It is of importance to study and predict the possible buckling of submarine pipeline under thermal stress in pipeline *** soil resistance is not strong enough to restrain the large deformation of pipeline,high-order buckling modes occur very *** solutions to high-order buckling modes were obtained in this *** relationships between buckling temperature and the amplitude or the wavelength of buckling modes were *** solutions were obtained to predict the occurrence and consequence of in-service buckling of a heated pipeline in an oil *** effects of temperature difference and properties of subsoil on buckling modes were *** results show that buckling will occur once temperature difference exceeds safe temperature;high-order pipeline buckling occurs very easily;the larger the friction coefficients are,the safer the submarine pipeline will be.

摘要：本文针对M厂主铁沟的设计情况，模拟计算了其主铁沟的温度场分布，通过与其他主铁沟设计进行比较，优化了主铁沟内衬砌筑及主铁沟尺寸，使沟底及沟梆温度降到安全温度以下，以保证主铁沟在工作时间内的安全稳定。
