Embodiment Construction

[0018] specific implementation plan

[0019] Attached below figure 1 Shown embodiment is described in further detail to the present invention:

[0020] The energy-gathering panel solar water heater is characterized in that it consists of three parts: an energy-gathering panel (1), a heat-collecting and heat-storage barrel (5) and a bracket (8). The energy-gathering plate is fixedly connected with the heat-collecting and heat-storage barrel (5) by the bracket (8), and the heat-collecting and heat-storage barrel (5) is under the side of the energy-collecting plate (1), and the central axis (AB) of the energy-collecting plate (1) ) is perpendicular to the axis of the heat collecting and storing barrel (5), and intersects at the middle point of the axis of the heat collecting and storing barrel.

[0021] The described energy collecting plate (1) is characterized in that it includes at least one Fresnel focusing lens or overlapping Fresnel focusing lenses to increase the light so...

Abstract

The invention discloses an energy-collecting plate solar energy water heater, which is composed by an energy-collecting plate, a heat collecting and storing barrel and a bracket. The energy-collecting plate is characterized by that at least one Fresnel condensing lens or laminated Fresnel condensing lens is used to enhance high light source energy density; the heat collecting and storing barrel not only stores the heat, but also collects the heat, thus cancelling the individually installed heat collector. Accordingly, the energy-collecting plate solar energy water heater, not only greatly improves heat collection efficiency, but largely reduces heat dispersing loss; the strike resistance is dramatically intensified and manufacture cost is vastly lowered; compared with current full-glass vacuum pipe solar energy water heater, the energy-collecting plate solar energy water heater can reduce the entire cost by about 30% to 50%.

Description

technical field [0001] A solar water heater Background technique [0002] At present, the mainstream product of solar water heater is "all glass vacuum tube" solar water heater. It has the most mature technology and the highest market share, but its shortcomings are also obvious: [0003] 1. The price is too high. Generally, the 80-120 liter water heaters used by ordinary households cost as little as three to four thousand yuan, and those with better quality and slightly larger liters cost five to six thousand yuan, which is really unbearable for the common people; [0004] 2. Low thermal efficiency. Solar energy is a low-density energy source. The all-glass vacuum tube solar water heater generally only reaches about 30°C on sunny days in winter. It is not even good for bathing. If you want to use a water heater, you must use electricity or gas to heat it; [0005] 3. The heat dissipation loss is too large. Although the heat loss has been greatly reduced with the vacuum...
