  • the present invention can be included in the technical field of low power thermoelectric generators of the type that produce electricity by using the temperature change of the external environment, converting thermal energy into electrical energy. BACKGROUND OF THE INVENTION
  • Global warming involves many environmental disasters, such as a resurgence of hurricane seasons and their strength and power. This global warming has an anthropogenic activity associated. This situation, linked to the global depletion of fossil fuel usable deposits, will surely consolidate efforts to harness energy from unconventional sources.
  • thermoelectric generators it is required to guarantee the temperature difference between both ends, supplying and releasing heat by means of heating and cooling sources.
  • Thermoelectric generators are known from the state of the art that operate using the change of temperature of the external environment to convert thermal energy into electrical energy, such as those described in US20140338713 A1 and US20100078054 A1. This facilitates the collection of energy in places with wide temperature variations throughout the day, or extreme variations between day and night.
  • the use of low power thermoelectric generators in these spaces will be possible when the restrictions regarding the place of installation are resolved to ensure an adequate temperature difference between the heating and cooling sources of the generator.
  • the invention relates to a low power thermoelectric generation module for use of environmental thermal energy in variable climate zones.
  • the proposed module allows obtaining electrical energy from renewable energy sources, taking advantage of natural resources.
  • environmental thermal energy was being wasted and thanks to the present invention it can be used to provide electrical energy with many areas of the planet that, for different reasons, were isolated.
  • the proposed thermoelectric generation module is configured to produce electricity by changing the temperature of the external environment, that is, from thermal energy. It is especially useful to be used in places where there is a high temperature variability since it comprises a power generator with Peltier devices that increases its performance by increasing the temperature difference between its ends.
  • the module comprises a battery that allows the electrical energy generated to be stored, so it is not necessary to connect it to the electricity grid.
  • This allows the thermoelectric power generation module to be used in areas that have traditionally been isolated, away from the services of power supply networks. Another advantage associated with these technical characteristics is that it minimizes the environmental impact of providing electrical energy to those areas that until now were isolated. It eliminates the need to install other types of solutions that would involve, for example, expanding the electricity supply network, or that would cause these areas to remain isolated.
  • the module comprises a user interface block that allows its adaptability and connection to other equal modules.
  • the module comprises a user interface block that allows its adaptability and connection to other equal modules.
  • the module has power generating capacity at any time, even at night. For this it has heat retaining elements, which allow the heat absorbed by the day to accumulate to keep it overnight. It also includes cold distributing elements that allow, although it is very hot during the day, one of the areas of the module is kept at a low temperature to maintain the thermal difference necessary for its correct operation.
  • the battery is connected to an energy and storage quality control block that corrects the polarity of the electricity generated in the thermoelectric generator. Subsequently, this same block is responsible for storing the energy in the battery where it is kept until the moment when it is necessary to use it.
  • the thermal generator has a sandwich structure with a plurality of Peltier devices arranged in its central part. At the ends of each Peltier device are layers of heating and forced cooling that allow creating and maintaining a temperature difference between said ends.

In this way, the temperature is increased at one end of the thermoelectric generator. To prevent heat loss during the night, it comprises an insulating protector that can be for example a plastic cover or other material that achieves the same effect.
  • the module comprises, under the thermoelectric generator, a lower layer with a plurality of Venturi tubes. These tubes enter air that is accelerating during its journey, thus reducing its temperature. Thus, this lower layer is responsible for maintaining a low temperature even during the day at the corresponding ends of the Peltier devices.

  • thermoelectric generator has a sandwich structure with an intermediate layer with a plurality of Peltier devices (1). These devices are responsible for converting the difference in thermal energy at its ends into electrical energy. For this it is necessary to ensure that one end is at a temperature higher than the other. The greater this temperature difference, the more electrical energy is obtained.

  • This layer is arranged at the upper end of the module so that the sun's rays can directly affect the lenses (4).
  • Said lenses (4) are distributed on the surface of a protector of insulating material (5) which can be a plastic cover or other material.
  • the protector (5) covers the focal length and reduces heat loss during the night.
  • the module also comprises a lower layer (6) that has a plurality of Venturi tubes (7), arranged under the cold distribution layer (3) of the thermoelectric generator. This layer facilitates the cooling of the cold distribution layer (3).

The rest of the tube can have a constant section, with a diameter equal to the smallest diameter of the trunk configuration section. This air is accelerated as it travels through the tube, so that its temperature is reduced.
