Complete plate tube-sheet type photovoltaic hot-water module

Abstract

The invention discloses a complete plate tube-sheet type photovoltaic hot-water module, which comprises glass, an encapsulated photovoltaic cell, a copper ribbed tube, an insulating layer and a galvanized sheet. The encapsulated photovoltaic cell consists of a photovoltaic cell, ethylene vinyl acetate (EVA) coated on the upper and lower surfaces of the photovoltaic cell, a transparent composite fluorine plastic film TPT on an upper layer of the EVA, a black TPT on a lower layer of the EVA, and an aluminum absorber plate under the black TPT. The copper ribbed tube is welded at the back of the aluminum absorber plate through spot welding by a laser head; and the insulating layer and the galvanized sheet cover below the photovoltaic cell. A glass plate covers on the encapsulated photovoltaic cell; an air gap is formed between the upper part of the encapsulated photovoltaic cell and the glass plate; and the periphery is fixed by adopting an aluminum alloy frame. The complete plate tube-sheet type photovoltaic hot-water module can generate electricity and hot water simultaneously, and improve the overall efficiency of solar utilization.

Description

technical field [0001] The invention relates to a laser-welded whole-plate tube-sheet photovoltaic hot water module, which belongs to a solar photovoltaic photothermal comprehensive utilization device and is used in the field of solar energy utilization. Background technique [0002] Among the many renewable energy sources, solar power generation has the most technological content and development prospects, and building-integrated photovoltaic (BIPV) systems are considered to be the preferred photovoltaic (PV) power generation system (European 2010 PV development goals). The solar roof of UNI-SOLAR in the United States directly generates amorphous thin-film cells on thin steel sheets, and the steel sheets can be cut arbitrarily to achieve the width of the roof; the amorphous solar glass curtain wall of German RWE company has realized the gap between cells. "Wireless connections. The above two structures only focus on the cooling of the battery, without utilizing the cooling...

Problems solved by technology

However, at present, the heat absorbing plate in the solar flat water heater is mainly composed of multiple thin copper sheets. The success rate of combining photovoltaic cells with the process and the series-parallel connection between the cells are also greatly limited. Therefore, with traditional designs and processes, the performance of solar photovoltaic water heating technology cannot be guaranteed, and it is difficult to standardize production. standardization
