Solar flat plate focusing medium-temperature heat collector plate core

Abstract

The invention belongs to the technical field of solar energy, in particular to a novel heat collector plate core with the parabola-shaped cross section. The plate core has the advantage that the adaptation capability of a solar heat collector to the illumination angle is obviously improved. A solar flat plate focusing medium-temperature heat collector plate core consists of heat collecting fins and heat collecting pipes fixedly connected with the heat collecting fins, and is characterized in that the cross sections of the fins are in crescent shapes, the fins consist of two parts including inner fins and outer fins, the outer walls of the outer fins have the parabola-shaped cross sections, the inner sides of the parabola-shaped cross sections are provided with flat plate-shaped inner fins in integral structures, a cavity with the crescent-shaped cross section is formed at the bottoms of the fins, and the heat collecting pipes are arranged in the middle of the cavity. The invention aims at providing the novel heat collector plate core capable of maintaining good illumination angles at different illumination angles.

Description

technical field [0001] The invention belongs to the technical field of solar energy, and in particular relates to a novel heat collector plate core with a parabolic cross section, which significantly improves the adaptability of the solar heat collector to the sunlight angle. Background technique [0002] Solar water heater installations usually include solar collectors, water storage tanks, pipes and pumps and other components. In addition, heat exchangers, expansion tanks and power generation devices are needed in winter to prepare for power plants that cannot supply power. A solar collector is a device that receives solar radiation and transfers heat to a heat transfer medium in a solar thermal system. According to the heat transfer medium, it can be divided into liquid collector and air collector. According to the way of lighting, it can be divided into two types: non-concentrating and concentrating collectors. A good solar collector should last 20-30 years. Thermal ...

Problems solved by technology

Although in theory the heat absorption capacity of the collector can be greatly improved by adjusting the incident angle of sunlight, it is difficult to achieve the above-mentioned adjustment in actual use, because the solar collectors are installed outdoors, and wind and rain hit, exposed to the sun and rain, and its use environment is very harsh

Although someone uses a mechanical mechanism that can be rotated and adjusted to achieve the above-mentioned angle adjustment work, its service life is very limited, and it is difficult to use it with a long-life plate solar collector.

The above-mentioned technical problems have existed in the industry for a long time, but there have been no very effective technical solutions
