嬰兒食品之保鮮及加熱裝置設計

本研究目標為設計一嬰兒食品之保鮮及加熱裝置。市面上現有相關產品均是將保鮮和加熱功能分開，例如小冰箱和食品加熱器，但對於新生兒母親來說，外出時必定希望能減輕攜帶重量且方便使用，故本研究重點在於將保鮮和加熱功能結合，利用熱電致冷晶片製造出冷熱面，並以結合儲熱塊和相變材料的概念，將浪費掉的能源回收再利用。儲熱塊的設計除了利用實驗驗證之外，藉由ANSYS CFX模擬分析相變材料於儲熱塊內的相變情形，分析熱源位置、儲熱塊結構和整體裝置效率，再根據模擬結果將保鮮及加熱裝置實際設計與製作出來。

This research is to design a preservation and heat storage device for baby food. The functions of preservation and heating are usually separated in two products (one product one function) in current market, such as tiny refrigerator and food heating device. However, for the newborn mothers, they expect to carry lighter weights and to feed the baby more easily. As a result, the main purpose of this research is to invent a device which combines the functions of preservation and heating together, by using thermoelectric cooling chip to create freezing side and heating side. In addition, this research realizes the concept of using heat storage blocks with the phase change material inside to reuse the wasted energy come from heating side of the device. The design of heat storage blocks is verified by the experiments, besides; simulation of the phase change phenomenon in the heat storage blocks is also done with the ANSYS CFX to know the mechanism of phase change of phase change material in the heat storage block. After analyzing the position of heat source, the structure of heat storage blocks, and the efficiency of integrated device, a preservation and heat storage device according to simulation results will be designed and produced.
