Heat Pipe
With" Safe, Reliability", "use well in the winter " as the design idea, "Solar water heater with double-effect pipe" mainly is designed as a safer and more efficient water heater for defects of solar water heater in the existing market.

First, it has been solved that in winter solar water heater can not be uesd in the alpine region from the scope of use. "The solar water heater with double-effect pipe" can still work in harsh environment of below 40 degree and will not fried tube when water freezing of the glass tube

Secondly, from the security, the problem of "The flood"and "paralyzed" has also been solved because of the broken glass tube for the general solar water heater. Because there are no water in the glass tube, it won't cause the whole water heater freezes and floods if single pipe ruptured.

Still, it has a save heat medium for solar water heater with double-effect pipe, which make its thermal power is higher 11% than ordinary water heate with vacuum tube, and can also be used in a cloudy and rainy day.

As a patent technology "Solar water heater with double-effect pipe" provides a solar collecting and applying system with low cost, high efficiency and the whole region, it can realize collecting and using of solar, especially with heat pipe technology of low cost, high-performance and adoptting high-efficient heat transfer between heat pipe and the vacuum tube, exchanged copper tube for low-cost carbon steel or aluminum, so greatly reduces the overall cost. It adopt fluid to heat exchange between heat pipe and vacuum glass tube, improving the heat pipe overall performance and reducing the cost, and providing a real practical techniques method which can be batch manufactured for heating, cooling and the application of hot water.
