In this study, a thermoelectric ice machine (TEIM) with a heat pipe was designed to save water and energy in ice making. Traditional ice machines have a long ice-making time. That is why they make ice and expend energy to maintain the ice form. Since the ice made is hand-harvested, it is likely to be contaminated. The proposed system saves energy by making ice fast when needed and saves water by making ice as needed. The ice machine was designed to freeze water in the icebox with direct thermal contact with the thermoelectric (TE) cooling unit. The cooling unit contains a TE module placed between the icebox and the heat-transfer system with a dual-fan heat pipe. Despite its low efficiency, the system has advantages such as compactness, portability, environmental friendliness and low maintenance requirements. The system turns 10 g of water into ice in 5 min by spending 0.025 kWh of power and harvests the ice automatically. It is possible to make 2880 g of ice per day using the TEIM. An important advantage of the system is that it harvests the ice automatically; therefore, it does not cause contamination.

热管热电制冰机设计：节水节能

在这项研究中，设计了带有热管的热电制冰机 (TEIM) 以节省制冰过程中的水和能源。传统制冰机制冰时间较长。这就是为什么它们会制造冰并消耗能量来维持冰的形态。由于制成的冰是手工采摘的，因此很可能受到污染。建议的系统通过在需要时快速制冰来节省能源，并通过根据需要制冰来节约用水。制冰机旨在通过与热电 (TE) 冷却装置直接热接触来冻结冰箱中的水。冷却装置包含一个 TE 模块，位于冰箱和带有双风扇热管的传热系统之间。尽管效率低，但该系统具有紧凑性、便携性、环境友好性和维护要求低等优点。该系统消耗 0.025 千瓦时的电力，在 5 分钟内将 10 克水变成冰，并自动收集冰。使用 TEIM 每天可以制作 2880 克冰。该系统的一个重要优点是它可以自动收冰；因此，它不会造成污染。
