| Summary: | 碩士 === 中華大學 === 機械工程學系碩士班 === 97 === Large-Scale High-Temperature Chamber applies in the industrial field more 20 years , having been existing temperature Uniformity will effect good yield argue of process on maximum space to use effectively of equipment inside cabinet.Particularly the industrial production line guide in more vendor of high-temperature chamber for mass-produce , even appear 4%~ 20% loss-yield and defect loss of high ratio difference in the same work order of product.Thereupon
,how to improve the design of flow field on Temperature uniformity of Large-Scale high-temperature chamber to be very important.
This thesis use as experiment measurement and 5 simulation steps of transient numerical analyze mode,inquiring into a discrepancy on difference part-assembly design in temperature uniformity of large-scale high-temperatrue chamber ( V=23.2 m3 ),equipment temperature rise capability and econom-izes on energy. Consequently Discover (1) the A fan-way design of the experiment equipment matching digital program controller,temperature unifomity could control in ± 2℃of GB national standard and can obtain to conform the High definition control of sequentias. (2) Fan-way design pattern of equipment is biggest item to effect equipment temperature rise capability, sequence item is change design on fan-box size and location place.(3) Compare E fan-way of equipment vender, A fan-way design could save 80% consume quantity of electricity.(4) wrong design and application of resistance on supply-way tuyere and return-way tuyere of Fan-box will reduce the equipment temperature rise capability.
The thesis have succeed to crating application technology of Numerical Simulation with Flovent software, in Temperature Uniformity of Large-Scale high-temperature chamber field. The Numerical Simulation mode and study result, can be used as the equipment vendor to apply Numerical Simulation technological development new equipment( or improve previously design) and apply the reference of the best manufacturing process equipment application of industrial user.
