Description

Technical field [0001] The invention belongs to the technical field of solar cell packaging and heat-collecting metal plate body heat storage and heat exchange in a solar PV / t system, and relates to a solar electric heating integrated comprehensive utilization installation board, and in particular to a double-sided groove for solar electric heating collection Mounting plate. Background technique [0002] In the development process of integrated solar power and heat storage equipment, the use of solar energy to obtain thermal energy is technically mature and relatively low in cost. However, in terms of solar energy application devices, technical equipment that can obtain both solar thermal energy and electrical energy has not yet been mature. [0003] At present, most of the products sold by the integration of solar and electric heating are heating, heat exchange and storage, and most of the water or oil is used as heat storage medium. In the field of solar high temperature applica...

AI Technical Summary

Problems solved by technology

Using water or oil as the heat storage medium has a large expansion coefficient when heated, so the heat storage box cannot store the same amount of expansion heat volume, and only a small box based on the expansion coefficient is added outside the energy storage box as a heat sink. Medium expansion overflows the storage container (expansion tank), which not only complicates the structure, but also is unsightly and unsafe, and increases manufacturing and installation costs

When this liquid heat storage medium is heated, the temperature of the upper layer and the lower layer of the mesons are different. Due to the spatial structure of the heat storage cavity, the heated mesons will flow upwards, resulting in extremely uneven temperature on the heating surface of the equipment, which seriously affects the silicon-based solar cells. The power generation capacity is high, and the hot spot effect of the solar cell is increased due to the large local temperature difference of the surface temperature, so long-term use will damage the P / N junction of the silicon-based solar cell, and even burn the solar cell at high temperature

Today, there is no practical and high-efficiency solar electric heating integrated equipment on the market today. Therefore, a product that can avoid potential safety hazards due to uneven temperature and liquid heat storage meson expansion is developed. It is used to encapsulate solar cells and has heat storage and cooling effects. The installation of the slab is imminent
