一般保溫瓶的設計是透過降低傳導、對流及輻射三種熱傳方式，成功延長保溫時間，讓使用者能喝到風味正佳又暖人心脾的熱飲。本研究使用商業套裝軟體COMSOL進行熱模擬分析並搭配田口方法設計最佳化之參數組合，成功開發具有溫室效果之示溫儲熱容器，不僅降低前述三種熱傳，還增加不同於以往保溫瓶的保溫方式與其他新穎性功能。首先，為了使熱能有效利用、得知飲品的最佳飲用時機及避免喝到溫度過高的飲品，本研究成功開發出合適的示溫儲熱材料，並將它利用在儲熱容器上，使其具有將高溫液體快速降溫至合適飲用溫度區間的功能；其次，本研究利用不同顏色組合的示溫方式，讓使用者能輕易知道儲熱容器內飲品之溫度，以掌握最佳飲用時機；最後，本研究使用具有波長選擇性之高分子聚合物製作儲熱容器外殼，可擷取太陽熱能並封鎖熱飲放射出之輻射熱於容器內，使該儲熱容器內部產生溫室效應，以延長保溫時間。上述研究成果均透過有限元素數值方法與實驗結果相互對照，驗證其合理性及正確性，確認所開發具有溫室效果之示溫儲熱容器能調節溫度、提示溫度及利用溫室效果維持飲品溫度。

Conventional thermoses often realize heat preservation by lowering heat transfer through conduction, convection, and radiation all. However, since there is no perfect thermal insulation and heat leaks out till thermal equilibrium is reached, retaining heat for a very long time Is quite challenging. In this study, we proposed a container and optimized its performance using Taguchi methods and COMSOL Multiphysics®. We then fabricated the optimized container using heat storage materials to display temperature and realize greenhouse effect.
This container actually holds three novel features. First, it adjusts temperature of beverage to fit in optimum drinking temperature zone using thermal storage materials. Second, it indicates current temperature of beverage inside by the displayed color. This way, the color of a thermochromic materials can notify users the best drinking time while beverage temperature changes. Third, it extends the heat preservation time of the beverage by greenhouse effect. It even gains heat to compromise the loss under solar light.
