一体承压太阳能热水器工作原理及特性：

1） 一体承压太阳能热水器工作原理及特性：

一体承压式太阳能热水器，是利用真空管所具有的高太阳吸收比和低发射比涂层，将吸收的太阳辐射转换成热能，通过插在真空管内的相变铜导热管迅速传至水箱内，使整个水箱内的水温逐渐升高。真空管对太阳具有自然跟踪的能力，只有有太阳辅射，真空管就可工作;由于相变热导管具有单向传热特性，即使高寒地区，一年四季均可高效运行。

承压式太阳能热水器特点：

◆超导热管单向传热，热容小，起动温度低，速度快;

◆超导热管管具有良好的耐低温性，在环境温度很低的状态下也不会冻裂; ◆水箱内胆采用高频焊接，热水器额定承压为0.6Mpa，可直接与自来水系统连接，承压使用，自动运行;

◆真空管内不走水，根除了因走水结垢使热效率下降的缺点;

◆真空管内不走水，根除了炸管或硅胶圈老化而漏水的缺点;

◆真空管内不走水，即使在严寒条件下也不会冻裂;

◆单根管损坏，热水器仍可正常运行;

◆全自动承压运行，并能实现管道排空。

The integrated pressure solar water heater working principle and features:

integrated pressure solar water heater type which is use of vacuum tubes‘s high absorbing ratio and low emission ratio of coating, the absorption of solar radiation converted into heat energy, through the phase change of the inserted in the vacuum tube copper heat pipe rapidly spread to water tank, make whole tank water temperature gradually increased. Vacuum tube has natural tracing ability to the sun, only have the sun radiation, the vacuum tube can work; Due to phase change heat pipe with unidirectional heat transfer properties, even if the cold area, all the year round all can run efficiently.

Characteristics of pressure type solar water heater:

Unidirectional heat superconducting heat pipe, heat capacity is small, low temperature starting, speed is fast;

Superconducting heat pipe mixer tube has good low temperature resistance, under the conditions of ambient temperature is low and not frost crack;

Pieces of the water tank using high frequency welding, water heater pressure is 0.6 Mpa, can be connected directly with the tap water system, pressure, automatic operation;

No water running in the vacuum tube, eliminated for fouling in water decreased thermal efficiency of defects;

No water running in the vacuum tube, the eradication of the blast pipe or silica gel ring aging and leaking defects;

No water running in the vacuum tube, even in cold frosty conditions will not;

Single tube damage, water heater can still run normally;

Automatic pressure run, piping can be emptied.
