In the cup, the phase change metal is filled between the internal heat conduction layer and the external heat insulation layer, and the hot water releases heat to the phase change metal through the heat conduction layer, so that the phase change metal absorbs heat and melts rapidly, and the temperature of the hot water drops rapidly.
Subsequently, when the hot water cools, the phase change metal solidifies and releases heat, which can keep the temperature of the hot water near the melting point of the phase change metal for a long time, thus achieving the effect of heat preservation.
55-degree Cup: It was launched by Beijing 55-degree Technology Co., Ltd. in June 20 14, and won the Red Dot Award for German Industrial Design in 20 15.
