真空集热管热水器的工作原理是什么?

真空管经太阳辐射,管内壁选择性吸取涂层吸取太阳能与管内的水进行热交换,使管内的水温上升,密度削减.
The vacuum tube is radiated by the sun, and the inner wall of the tube is selectively absorbed by the coating to absorb heat from the solar energy and the water in the pipe, so that the water temperature in the pipe is increased, and the density is reduced
与水箱内的水产生了密度差潍坊设计,形成热虹吸压头,水箱内的水在不借助外力的情况下主动完成循环,从而实现加热的过程。

The water in the water tank is designed to generate a density difference of the Weifang, and a hot siphon pressure head is formed, and the water in the water tank can complete the cycle without the aid of an external force so as to realize the heating process.

真空管集热器是在玻璃壁与吸热体之间抽成肯定的真空度,以克制空气的对流和传导热损。

The vacuum tube heat collector is a certain vacuum degree between the glass wall and the heat absorbing body, so as to restrain the air convection and conduction heat loss.

吸热体外观镀上一种特别的涂层代替黑色的吸热板,还可克制吸热体的辐射热损。
In view of plating on a heat absorbing plate special coating instead of black, also can restrain radiation heat loss of absorber.
因此,真空管集热器具有比通俗平板型集热器更精良的热性能。在高温文低温环境下均有较高的集热服从。真空管集热器按其材料结构可分为全玻璃型和金属吸热体型两大类。
Therefore, the vacuum tube collector has better thermal performance than the conventional flat plate collector. Under the condition of high temperature and low temperature, it has higher heat collection. Vacuum tube collector can be divided into two types: the full glass type and the metal heat absorbing material.
其中全玻璃真空南京皇明太阳能集热管具有透过率和吸取率高、热反射率低、对流热损小以及全年使用时间长等精良特征,同时制造工艺简便,技术成熟可靠,成本较低,全玻璃真空管热水器的使用日益广泛。
The full glass vacuum Nanjing highmien solar energy heat collector has the transmittance and absorption rate of high and low reflectivity, thermal convection heat loss is small and the long service excellent characteristics, and simple manufacturing process, mature and reliable technology, low cost, the use of all glass vacuum tube water heater is more and more widely.
