Problems solved by technology
The cost is getting higher and higher, and the volume is getting bigger and bigger, but the thermal conductivity remains unchanged. If you choose a new material with a small thermal conductivity to achieve a good heat preservation effect without increasing the cost of materials, how to apply it to solar water heaters? Research topics are urgently needed

Embodiment Construction
[0011] The nanocomposite material is cut according to the specified size, and the composite material packaging bag (3) is sealed on three sides. Put the honeycomb paper (4) and getter (5) into the packaging bag (3), seal the other side, and leave 1. Air pumping port, before pumping air, put it into the well-positioned outer water tank (1) and inner water tank (2) space, use a vacuum pump to make a vacuum, seal and seal, use the same method to make vacuum discs and put them on both ends. Seal the end cap and it is successful.

A novel solar water heater with a glass heat collection vacuum tube includes a thermal-insulation water tank made of a novel vacuum thermal-insulation material with the best thermal insulation effect instead of the conventional polyurethane foaming material. Accordingly, the solar water heater can protect environment, save energy and insulate heat.
Description
[0001] Technical Field The present invention relates to a solar water heater, a solar water heater which uses a new type of vacuum insulation material to keep the water tank warm. Background technique [0002] Solar water heaters are divided into two key parts: heat absorption and heat preservation. The heat-absorbing part is currently the most used glass vacuum heat-collecting tube. There is a black material inside to absorb the heat of the sun. The effect is obvious. The sun can be irradiated for half a day to heat a tank of water. For more than ten years, people in the industry have always paid attention to the research on heat absorption, while ignoring the importance of heat preservation. [0003] The insulation part refers to the water storage tank with insulation layer. For a long time, the insulation layer has been foamed with polyurethane material to generate a large number of pores to achieve the purpose of insulation. The insulation water tank plays a very importan...
