內翅片用于相變材料儲存(PCM)。在汽車工業等幾個實際領域中,PCM被用來平衡暫時的溫度變化和儲存能量。利用內翅片可以大大提高流體通過微通道的傳熱速率。T。Kanthimathi[1]重點研究徑向復合翅片,以提高其在多種應用中的傳熱速率。y Pratapa Reddy[2],制作圓形針鰭由不同的金屬,鋁、銅、鋁和銅和銅和銅作為復合酒吧和分析他們的表現的翅片效率、傳熱率和江沿翅片溫度分布。[3]測量傳統硅膠涂層換熱器的性能(SGCHE),一種新的復合硅膠涂層換熱器提出了(孕婦)和捏造。吳學紅[4]對雷諾數Re = 304 ~ 2130范圍內的空氣側傳熱和流體流動進行了數值模擬研究。本研究的目的是研究復合內縱翅片在圓管入口區域和完全發達區域對傳熱特性的影響。本試驗采用砂型鑄造工藝制造黃銅管。復合材料是由98%的純鋁制成的。在這個實驗中,純碳化硅被用于10%的重量分數與鋁。加入Mg (1wt %)可改善陶瓷顆粒的潤濕性和摻入率。采用微尺度碳化硅顆粒作為純鋁的增強劑,制備鑄鋁基復合材料,并加入Mg (1wt %)改善陶瓷顆粒的潤濕性和摻入率。

Internal fins are used in phase change material storages (PCM). PCM are used to balance the temporary temperature alteration and to store energy in several practical fields like automobile industries. The rate of heat transfer from fluid flowing through the micro channels can be greatly enhanced by use of internal fins. T.Kanthimathi [1] focused on the study of the radial composite fins to increase the heat transfer rate in many applications. Y. Pratapa Reddy[2] made to fabricate circular pin fin made of different metals, Aluminium ,Copper, combination of Aluminium and Copper and combination of Brass and Copper as composite bars and analyzed their performance in terms of fin efficiency , heat transfer rate and temperature distribution along the fin. Jiang[3] measured the performance of conventional silica gel coated heat exchanger (SGCHE), a novel composite silica gel coated heat exchanger (CCHE) was proposed and fabricated. Wu Xuehong[4] investigated the performance of air-side heat transfer and fluid flow by numerical simulation for Reynolds number ranging from Re = 304 to 2130. The objective of the research is to study the effect of composite internal longitudinal fins in a circular tube on heat transfer characteristics in the entrance region as well as in the fully developed region.Sand casting was used in this experiment to manufacture brass pipe. Composites were made from 98% pure aluminum. In this experiment pure SiC was used in 10 % weight fraction with aluminum. Mg (1 wt %) was added to improve the wettability and incorporation fraction of ceramic particles. Micro-sized SiC particles were used as reinforcement of pure aluminum to fabricate as-cast aluminum matrix composite, and Mg (1 wt%) was added to improve the wettability and incorporation fraction of ceramic particles.
