Embodiment 1

[0049] As shown in Figure 1-3, it is composed of two parts: a concentrating tile and a heat exchange tube; the outer surface of the concentrating tile is an arched polycarbonate lighting surface 1, and the two sides of the lighting surface 1 are provided with a water tank 2 and a water tank. Connecting ear 3 is arranged on the outside of 2, and fixing hole 4 is arranged on connecting ear 3. The inner side of the concentrating tile is provided with a Fresnel lens, and the thickness of the interfering side of each edge tooth 10 of the Fresnel lens is set to gradually become thinner from both ends to the center; the aluminum heat exchange tube 5 is arranged in the middle of the bottom of the concentrating tile Position; the inner wall 8 of the heat exchange tube 5 is in the shape of a sunken groove, the heat transfer medium cottonseed oil 9 is arranged between the inner wall 8 and the outer wall 7 of the tube, and the outer wall 7 of the tube is provided with an insulating layer 6...

Embodiment 2

[0051] The lighting surface 1 is arranged in a plane shape, the heat exchange tubes are made of copper embedded series blind tubes, the heat transfer medium is soybean oil, and the other structures are the same as in the first embodiment.

[0052] 1. The present invention realizes self-adaptive tracking without tracking components and focuses on vertical and horizontal tracking strategies as follows:

[0053] (1) Longitudinal (north-south) offset

[0054]In the four seasons, the sun is based on the equator (0°), the sun moves northward by 23.5° on the summer solstice, and moves southward by 23.5° on the winter solstice. In order to make the light coming from the sky positively incident on the static concentrating tiles on the ground, it should keep a certain north-south inclination with the horizontal plane synchronously. Its value is the sum of latitude and offset angle every day. For example, on the winter solstice day, the inclination angle of the Shenyang concentrating ti...

Abstract

The sunlight tile capable of absorbing solar energy effectively for utilization consists of two parts, including one light gathering tile and one heat exchange tube. The light gathering tile has outer arched or plate lighting surface and Fresnel lens in the inner side; and the heat exchange tube is set below the light gathering tile. The sunlight tile can absorb solar energy effectively and can realize adaptive tracking focusing without tracking unit except the traditional functions of keeping rain and hail out.

Description

technical field [0001] The invention relates to a tile, in particular to a solar tile capable of effectively absorbing and utilizing solar energy, which can be used as a tile for building houses. Background technique [0002] The use of solar energy, a new energy source with high thermal efficiency and no pollution to the environment, has gradually attracted people's attention. However, there are still certain limitations in the popularization of solar energy applications, which are mainly reflected in: [0003] 1. The temperature is not high. When boiling water (or steaming food), the heat source must be above 100°C. It is difficult to use natural sunlight for heat collection, and the cost and maintenance of focused heat collection and tracking are also difficult to accept. [0004] 2. The heat is not enough. When boiling a certain amount of water or heating in winter, the total heat required needs a large enough lighting area to meet it. Therefore, it is affected by vario...
