Rigging non-tracting focusing vacuum piping solar water heater

Abstract

A fixed ridge style solar vacuum tubular focusing water heater consists of a triangular frame, a tank on its top, a heat-conducing cylinder beneath and connected with the tank, two sets of vacuum heat-collecting tubes installed on both side of the said cylinder, and focusing strips installed under the said heat-collecting tubes. The cylinder is little higher than the both edges of the frame to form a ridge. The declination of the ridge depends on direction of sunshine to make it perpendicular to the cylinder in the noon in the winter. It can produce hot water in winter and prevent from boiling in summer at anywhere.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a roof ridge type tracking-free focusing vacuum tube solar water heater. It is suitable for any place where solar water heaters can be installed in the north and the south. Background technique [0002] At present, solar water heaters are widely used clean energy devices. They do not pollute the environment, do not require fuel costs, and can save energy and money, so they are widely welcomed by people. But so far, the general direct-sprinkling solar water heaters sold on the market are generally ordinary type solar water heaters. The vacuum heat collecting tubes are arranged in a single row north and south, and the heat absorption effect is poor. Too poor to use in winter. And in the summer when the temperature is high and the sunshine time is long, because the water temperature is too high and boils, scale will be generated on the inner wall of the vacuum heat collecting tube, which wi...

AI Technical Summary

Problems solved by technology

However, most of the direct spray solar water heaters sold on the market so far are ordinary type solar water heaters. too poor to use in winter

In the summer with high temperature and long sunshine time, the water temperature is too high and boils, which will cause scale on the inner wall of the vacuum heat collecting tube and affect the heat absorption efficiency.

[0003] In order to solve the above problems, tracking-type focused solar water heaters have been invented successively in recent years at home and abroad, such as patent numbers: ZL01263358. , or mechanical tracking concentrating solar water heaters have disadvantages such as complex structure, high production cost, and easy failure, so it is difficult to popularize and use
