Water inside vacuum heat- collection tubes; since the hot medium inside vacuum tubes floats up and cold one goes down due to respective specific gravity, hot and cold mediums convections up and down to cause the heat conduction, furthermore transfer the heat to the related working medium in the heat tubes, the working medium sorbs the potential heat and becomes steam to rise up to the condensing section from the tube heat evaporating section; it emits the heat in condensing section to change again into liquid working medium; it flows back to evaporating section under the gravity action, the emitted heat is transferred into the water inside water tank or tube group by means of the heat-conduction through heat tubes condensing section; it makes the cold water in water tank into hot water in the repeated way.

阳光透过全玻璃真空集热管的外玻璃，照射到涂覆在内玻璃管外表面的选择性吸收涂层上，涂层将太阳的辐射能吸收并转化为热能，通过内玻璃管壁导热，传递给真空集热管内其液态传热介质，由于真空集热管内热的介质因比重小而上浮，冷的介质因比重大而下沉，冷热介质上下对流传热和导热，再通过热管的金属壁导热，将热量传递给热管内其相变工质，工质吸收汽化潜热而变成蒸汽，由热管蒸发段上升到冷凝段，在冷凝段放热冷凝，又变成液态工质，在重力作用下流回蒸发段，所放出的热量通过热管冷凝段金属管壁导热，传递给水箱或联集管内的冷水，周而复始，于是便将水箱内的冷水全部加热成热水。
