Problems solved by technology
[0004] However, the cost of photovoltaic power generation is high, the efficiency of power generation is low, and photovoltaic power generation can only supply power during the day. The discontinuous power supply is a fatal flaw of photovoltaic power generation. It must be supplemented by other power supply methods to overcome this problem.

Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.
[0025] The temperature difference between day and night is large in desert areas, and the ground temperature at noon in summer can reach above 60°C, and the ground temperature drops below 10°C at night. The module group is closely attached to the heat sink that absorbs heat. At this time, the upper surface of the thermoelectric module group is a heat sink, and the lower surface is a vapor chamber. The thermoelectric module group is based on the temperature difference betwee...

The application provides a thermoelectric conversion system for day and night operation in desert areas, and relates to the technical field of thermoelectric conversion. Taking advantage of the climate characteristics of large temperature difference between day and night in desert areas, based on the thermoelectric conversion technology of thermoelectric materials, a power generation system that can be used in desert areas and can operate continuously day and night has been invented. The thermoelectric conversion system operating day and night includes: a first thermoelectric conversion subsystem, a second thermoelectric conversion subsystem and a heat storage metal pool. The first thermoelectric conversion subsystem works during the day, and is used to convert the heat absorbed during the day into electric energy, and conduct the absorbed heat to the heat storage metal pool, so that the heat storage metal pool can complete energy storage during the day, and the second thermoelectric The conversion subsystem operates at night to convert the heat stored in the heat storage metal pool into electric energy to complete power generation at night. The first thermoelectric conversion subsystem and the second thermoelectric conversion subsystem operate alternately in the above-mentioned manner to complete the day and night power generation. Purpose.
Description
technical field [0001] The present application relates to the technical field of thermoelectric conversion, in particular to a thermoelectric conversion system for day and night operation in desert areas. Background technique [0002] The desert area in the world accounts for almost 20% of the land area. On the one hand, more than 1 billion people are directly threatened by deserts, and on the other hand, a large number of people still live in remote desert areas. my country's desert area is about 1.3 million square kilometers, and a considerable number of towns are located in the desert hinterland. Under the existing technology, the distributed power system is generally used to supply power to remote desert areas. [0003] In the distributed power system, in addition to the traditional power production methods (such as coal, oil and gas fueled power stations), photovoltaic power generation is one of the main technologies to solve the power supply in remote desertified area...
