Problems solved by technology
[0002] At present, there are two types of solar energy utilization. The first is the photoelectric conversion type solar panel, and the conversion rate is less than 20%.
The second is the light-to-heat conversion type, and its typical product is a solar water heater, which is widely used, but the cost is also high
Therefore, the current utilization of solar energy and the development of products all have the contradiction of low efficiency and high cost.

Embodiment Construction
[0011] Such as figure 1 As shown, when the partition type solar collector 1 faces sunlight and is heated, the hot air flow rises, and is heated step by step along the grooves formed between the partitions 2, and the temperature rises step by step, and finally reaches the upper cascade hole 3, The temperature reaches maximum. If the temperature does not meet the usage requirements, it can also be solved by increasing the cascade. If the heat collecting tube 7 is installed, the liquid in the heat collecting tube 7 li also flows from bottom to top, rises step by step, is heated step by step in the rising process, and reaches the maximum value when reaching the outlet. Both the principle and the experiment have proved that the solar heat collector has the functions of enriching and concentrating solar heat energy and increasing the temperature of air and liquid. Due to the high light-to-heat conversion efficiency of this collector, the temperature rises quickly, and in summer i...

The invention relates to a clapboard-type hexahedral solar heat collection device with a cube structure. The solar heat collection device comprises a light-transmission lighting surface and five thermal insulation and heat preservation surfaces. A plurality of layers of clapboards are horizontally arranged in the cube; an air passage is arranged at one end of each clapboard; the air passages of adjacent clapboards are arranged at two ends; both the inner surface of an heat insulation layer and the surfaces of clapboards are coated with deep color lighting heat-absorbing coatings; and cascade air holes are formed on the upper side and the lower side of the cube. The air ascends increasingly through grooves between adjacent clapboards through lower air holes, is heated by sunlight step by step, thereby achieving the effects of enriching and concentrating solar heat energy and improving the temperature of the air or a liquid. Collectors can be connected in series or in parallel or both in series and in parallel to form a clapboard type solar collector array. The collector array equipped with a solar heat collection central control instrument, a water heat exchanger, a gas flow controller, a water flow controller, a temperature sensor, a heat preservation water tank, a pipeline to form the clean and cheap solar heating system.
Description
technical field [0001] The invention patent belongs to the field of solar energy utilization. Background technique [0002] At present, there are two types of solar energy utilization. The first is the photoelectric conversion type solar panel, and the conversion rate is less than 20%. The second is the light-to-heat conversion type, and its typical product is a solar water heater, which is widely used, but the cost is also relatively high. Therefore, there are contradictions of low efficiency and high cost in the utilization of solar energy and the products developed at present. Therefore, a cheap and high-efficiency solar heat collecting device is designed to solve the economy of solar energy utilization. Compared with the current solar water heater, it has higher thermal efficiency and lower cost. It is expected to push the utilization of solar energy to a cheap and practical new stage, bring benefits to the common people, and have a positive effect on the country's ene...
