Overall plastic solar heat collector

Abstract

The invention relates to a plastic solar-energy heat collector, wherein a frame has a transparent cover plate via pad supported between two layers of ultra-fine plastic sheets, the outer face of the cover plate is coated with nanometer solid material, a heat absorber has parallel connected corrugated ultra-fine plastic sheets whose section is in Omega-shape, while the sun-face of the absorber is coated with a selective heat absorption coat coated with nanometer solid material, and the heat exchange container is a ultra-fine heat exchanger in parallel semi-cylinder straight tube shape with interlay, while the interlayer contains strengthen ribs, and the outer wall of the tube contacts the bottom of the heat absorber, the end of each semi-cylinder straight tube is parallel connected with water tubes at two ends, two ends of the tube head are supported via base, and a thermal-insulated layer is at the back of the base. The invention has supports as plastic combine posts which are uniformly distributed on building via passing through the transparent cover plate, the heat absorber and the thermal-insulated layer. The invention has low cost and maintenance free.

Description

Technical field [0001] The invention relates to a solar heat collector. Background technique [0002] Solar energy is a renewable, non-polluting energy source, and the use of solar energy is the development direction of energy-saving buildings. However, the existing solar collectors are mainly used in domestic solar water heaters. By 2006, the national inventory has reached 80 million square meters, and it has an important position in the field of renewable energy utilization. The state plans to increase the area of ​​solar water heaters to 3 by 2015. 100 million square meters, the annual energy saving is equivalent to 40 million tons of standard coal. Traditional solar collectors mainly include flat plate solar collectors and vacuum tube solar collectors. The main problems are: First, the high cost makes the promotion slow, the second is the maintenance difficulty caused by the low reliability of the process materials, and the third is that the shape structure of the solar colle...
