Description

An energy storage type solar flat collector with added metal fins technical field The invention relates to the technical field of solar energy, in particular to the technical field of a solar thermal collector device capable of storing energy. Background technique The heat storage technology of phase change materials has been widely promoted and applied in the air conditioner, solar energy industry and building energy saving, mainly because of its excellent heat storage performance. Combining phase change materials with flat plate collectors does not require additional storage tanks. It can not only meet the requirements of building integration, but also realize the continuous supply of energy and the constant temperature of the water supply. However, the inherent characteristics of the existing organic phase change materials are low thermal conductivity and slow heat transfer, resulting in poor energy storage effect and low energy storage efficiency. Especially the dis...

Problems solved by technology

However, the inherent characteristics of the existing organic phase change materials are that the thermal conductivity is small and the heat transfer is too slow, resulting in poor energy storage effect and low energy storage efficiency.

Especially the discontinuity and discontinuity of solar radiation and the low thermal conductivity of phase change materials, the speed of phase change energy storage is very low
