| Keyword | 大功率导电膜 最佳工艺条件 理论与实验对比 高效节能 |
| Abstract | 本文研制了一种新型的大功率导电薄膜。利用薄膜技术的理论知识，通过大量的实验研究，选择了能满足大功率发热膜的基材及源材，在保证薄膜良好性能的基础上，确定了设备简单、成膜周期短且能适应大面积薄膜生长的实验方案；研究了薄膜的导电机理以及影响薄膜性能的各种参数，总结出最佳工艺条件。在此条件下生产的电热膜具有良好的欧姆特性和热稳定性。分别以电热膜和电阻丝为加热元件进行了热效率的对比实验。针对两种加热情况，进行了传质变分析，并用QUICK-BASIC语言进行了理论计算。实验结果和计算结果表明，电热膜与电阻丝加热元件相比，热损小，热效率高，确实具有节能的功效。 |
| Other Abstract | A new kind of electrical conductive film was studied and made in this paper. By the fundamental theory of film technique and a lot of experimental studies, the suitable base material and source material for large power heating electrical conductive film was obtained. The experimental method, which needs simple equipment, costs little, has short period of film formation and can form on a large area, has been proposed on the premise that the film has good properties. The film electrical conduction mechanism and various parameters affecting the film electrical characteristics have also been studied. The best technical conditions were concluded electrical heating film made under these conditions has good V-A characteristics and thermal stability. Moreover, comparative experiments on thermal efficiency was conducted, using electrical conductive heating film and resistance wire as heating component respectively. Heat transfer analysis on two cases above have been performed by numerical simulation. And theorical calculation was done by a computer program in QUICK-BASIC language. Both experimental and numerical results indicate that using electrical heating film as heater has much higher efficiency than using resistance wire, and has excellent effect of saving energy. |
