新型热管防烫筷子的快速导热性研究

为了解决高温食物不能立即食用的缺陷,基于热管技术,本文设计并制作了一种能够使高温食物快速冷却的热管防烫筷子,主要由微型热管、防滑螺纹和隔热握柄等组成.以食物冷却速度为指标,测试了使用热管防烫筷子搅拌冷却高温食物(90 ℃)的降温效果.试验结果表明,高温食物降低相同的温度,使用热管防烫筷子能够明显缩短冷却时间,相比同材质金属筷,使用热管防烫筷子冷却高温水、油菜、龙须面和方便面的速度分别提高28.8%,29.0%,28.7%和28.5%,相比竹筷,冷却速度分别提高36.7%,37.6%,35.2%和35.4%.

Study on the fast thermal conductivity of a new type of heat pipe anti scald chopsticks

In order to solve the defect of high temperature food can' t precook and ready to be eaten, based on heat pipe technology, a kind of heat pipe anti-scald chopsticks that could make high temperature cooling rapidly was designed, composed of miniature heat pipe, anti-slip thread and heat insulation grip handle.The cooling effect of heat pipe anti-scald chopsticks cooling high temperature food (90 ℃) was tested by food cooling rate as the index.The test results showed that: reduced the same temperature of high temperature food, compared with metal chopsticks, the cooling rate of high temperature water, rape, dragon whiskers noodles and instant noodles using heat pipe anti-scald chopsticks was increased by 28.8%, 29.0%, 28.7% and 28.5%.Compared with chopsticks, the cooling rate was increased by 36.7%,37.6%,35.2% and 35.4%.
