technical field

The utility model relates to a refrigeration device powered by solar energy, in particular to a solar refrigerator.

Background technique

At present, most of the refrigerators on the market are powered by the urban power grid, which needs to continuously provide power to ensure the normal operation of the refrigerator. Therefore, for some relatively remote areas or some nomadic peoples, the incomplete power transmission supply network limits the use of refrigerators. Moreover, the use of traditional refrigerators needs to consume a large amount of conventional energy, which indirectly causes serious pollution to the environment. For the shortage of traditional energy supply and the increasingly important environmental issues in the current society, traditional refrigerators are no longer suitable for the development of the times.

In order to overcome the shortcomings of the above-mentioned traditional refrigerators, people continue to develop and try to use clean energy for refrigerators, so as to overcome its dependence on traditional urban power grids, overcome its high energy consumption, great environmental hazards, and narrow application range.

If it is night or rainy, the unsustainable energy supply directly weakens the use of solar refrigerators. Especially for some portable solar refrigerators, the limited area of the solar panel limits the collection of solar radiation, that is, the collection of solar energy, resulting in a sharp drop in power generation. Therefore, how to maximize the acquisition and storage of solar energy in a limited time and a limited area of solar panels has become the key to breaking through the application limitations of solar refrigerators.
