Abstract

The invention relates to a heat-storage flat-plate solar heat collector. The heat-storage flat-plate solar heat collector comprises an aluminum frame body, a transparent glass cover plate, a photovoltaic module, a heat absorption plate, a PCM heat storage unit and a passage. The transparent glass cover plate and the heat absorption plate fixedly support and are connected to the middle portion andthe upper portion of the inner side of the aluminum frame separately through clamping grooves. The photovoltaic module is placed on the upper portion of the heat absorption plate. The lower portion ofthe heat absorption plate is filled with the PCM heat storage unit. The PCM heat storage unit is connected with a cooling medium inlet / outlet in the side face of the aluminum frame and is used for achieving integrated comprehensive utilization of solar photovoltaic heat and heat storage. According to the heat-storage flat-plate solar heat collector, the PCM heat storage technique and the solar photovoltaic heat technique are combined, so that temperature fluctuation of photovoltaic cells is effectively reduced, and the photoelectric conversion efficiency is improved; meanwhile, integrated heat storage of a solar energy utilization device is achieved, the challenges of instability and intermittency of solar energy are overcome, and a stable heat source can be provided to meet heat and temperature requirements in various time periods; and the heat-storage flat-plate solar heat collector is simple in structure and convenient to use, can be combined with a building easily, and can be widely developed and popularized.

Description

technical field [0001] The invention relates to the field of high-efficiency utilization of solar energy and phase-change energy storage, in particular to a thermal storage type flat-plate solar heat collector. Background technique [0002] As an important form of renewable energy, solar energy has the advantages of energy saving and environmental protection. It is of great significance to develop corresponding high-efficiency collection and utilization devices. Studies have shown that the temperature rise of photovoltaic cells reduces its photoelectric conversion efficiency. By using different cooling methods to cool photovoltaic cells, part of the waste heat can be used while ensuring photoelectric conversion efficiency, and multi-level utilization of solar energy has been realized. development prospects. [0003] The flat-panel photovoltaic photothermal integrated solar collector has a simple structure and low cost, and is easy to integrate with buildings. In traditiona...
