DESCRIPTION
DESC:FIELD OF THE INVENTION


Generally, the present invention relates to the unconventional source of electricity production. More particularly, the present invention relates to the thermoelectric generators.


BACKGROUND OF THE INVENTION


Electric power is a resource indispensable to our daily life and essential to economic development. There are different kinds of power generation, namely coal-fired power generation, nuclear power generation, etc. However, coal-fired power generation requires coal, petroleum, or liquefied natural gas (LNG) and thus has its own drawbacks, such as over-exploitation of resources and environmental pollution. Likewise, nuclear power generation takes place at the risk of radioactive leak, nuclear waste pollution, etc. Hence, plenty of countries allocate a lot of resources to research on different kinds of renewable energy.


Also, existing power generation devices are composed mostly of various moving parts and therefore have the following disadvantages: they cause environmental pollution, their moving parts produce noise when in operation, and replacement of worn-out moving parts incurs costs.


The Seebeck effect involves a temperature differential across the module by heating one side of the module and cooling the opposite. A Seebeck Module is a thermoelectric generator TEG and a Peltier Module is a thermoelectric cooling module TEC. You can use a TEC as a generator but will not be able to produce much power because of materials used to bond the device together are low temperature under 220°F. To produce meaningful power you will need to expose the hot side to temperatures well above 350°F range. Also have the cold side remove heat and maintain temperatures of 100°F or lower if possible. As such, a socket is needed which could cover all limitations which are mentioned above.


These thermoelectric principles have been known for more than a century, the extreme high cost of generating even a small amount of electricity has prevented any widespread use of these thermoelectric effects for power generation. In fact, previously the Seebeck effect has been employed almost exclusively for thermocouples. Thermocouples in accordance with the Seebeck effect allow temperature measurement based upon a current induced in couples of metals, such as PT-Rh or Fe-Constantan. However, these couples cannot be advantageously used to generate electricity.


SUMMARY OF THE INVENTION


The primary intent of the present invention is to provide a thermoelectricity harvesting device adapted to produce electricity according to a Seebeck effect when a thermal gradient is imposed across the heat receiving end and the heat sink.


In an intent the present invention provide a thermoelectricity harvesting device including; a first layer, a second layer a third layer and a fourth layer, wherein first layer is the heat conductive surface, the second layer is heat transfer mechanism; third layer is a magnetic plate; and the fourth layer is a heat sink.


Any of the embodiments disclosed herein for the energy harvesting devices may be mounted to a substrate that is part of a mobile device that experiences a temperature change as a result of its mobility.
