Embodiment 1

[0029] Such as figure 1 and figure 2 As shown, a photovoltaic module heat collecting device 1 includes a photovoltaic module 1, a heat collecting plate 2 and a supporting frame 3, and the photovoltaic module 1 and the heat collecting plate 2 are installed on the supporting frame 3, and the heat collecting plate 2 is connected to the heat conducting frame 5 of the photovoltaic module 1, the heat collecting plate 2, the heat conducting frame 5 and the back of the photovoltaic module 1 are surrounded to form a hollow heat exchange space 4, and the ventilation pipe 6 is connected to the heat collecting The back of the plate 2 is in communication with the heat exchange space 4, and the photovoltaic module 1 is composed of 8 single solar cells in 2 series and 6 in parallel.

[0030] Further, the material used for the heat conduction frame 5 is aluminum, and the material used for the heat collecting plate 2 is an aluminum-plastic plate.

[0031] Further, the heat collecting plate ...

Embodiment 2

[0034] The difference between this embodiment and Embodiment 1 is that the photovoltaic module 1 and the heat collecting plate 2 are obliquely installed on the support frame 3, and the ventilation duct 6 includes a The lower ventilation pipe 60 of the air inlet and the upper ventilation pipe 61 with an air outlet arranged on the inclined upper end of the heat collecting plate 2, the upper ventilation pipe 61 and the lower ventilation pipe 60 communicate with each other. After entering the inlet, the hot air will move upwards after being subjected to the backplane of the photovoltaic module 1 and the heat transfer temperature rise. Therefore, the hot air will move from the lower end to the upper end along the heat exchange space 4, and the push of the external air will accelerate the process. Movement, so that the air flowing in the heat exchange space 4 will quickly take away the heat on the back of the photovoltaic module 1 and the heat collecting plate 2, so that the heat dis...

The photovoltaic module heat collection device has the advantages of being rapid in heat exchange, high in heat collection, high in power generation efficiency of the photovoltaic module and the like.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a heat collecting device for a photovoltaic module. Background technique [0002] A single solar cell cannot be directly used as a power source. As a power supply, a number of single cells must be connected in series, parallel and tightly packed into a photovoltaic module. Photovoltaic modules (also called solar panels) are the core components and the most important part of solar power generation systems. Its function is to convert the solar energy into electrical energy, and store it in the battery or push the load to work. [0003] At present, there are two main ways to apply solar energy, one is photovoltaic power generation, and the other is solar thermal utilization. The efficiency of photovoltaic power generation is relatively low, only about 20%, and most of the remaining energy exists in the form of heat energy. The high-temperature heat energy accumulated on th...
