高壓燃氣熱風槍設計與探討

燃氣熱風槍在使用時會產生火焰不定向、不均溫、噪音過高等問題，造成加熱效率低、燃氣的浪費、作業安全疑慮等。本研究藉由電腦輔助技術的導入，完成測試樣品並打樣將測試數據化，藉由數據化的分析逐步找尋適當的改善設計。本研究藉由流體力學、產品設計及電腦輔助工程，並制定測試方法、自製冶具、分貝計、風速計及熱像儀等工具，藉由以大量測試本研究之高壓燃氣熱風槍樣品來獲得數據，作為改善下次樣品來達到優於目前市售品的標準，最後以量化方式來作市面上燃氣熱風槍與本研究之燃氣熱風槍數據的比較差異而獲得本研究之高壓燃氣熱風槍之優勢。

When the gas heat gun is used, it will cause problems such as flame non-directional, uneven temperature, high noise, etc., resulting in low heating efficiency, waste of gas, and operational safety concerns.In this study, the introduction of computer-aided technology, the completion of test samples and proofing data, the data analysis, and gradually find the appropriate improvement design. This research uses fluid mechanics, product design and computer-aided engineering, and develops tools such as test methods, self-made tools, decibel meters, anemometers, and thermal imaging cameras. Data was obtained by testing a large number of high-pressure gas heat gun samples of this study as a standard to improve the next sample to achieve better than current commercial products. Finally, the advantage of the high-pressure gas heat gun of this study was obtained by quantitatively comparing the difference between the gas hot air gun on the market and the gas heat gun data in this study.
