The power generation capacity depends on many factors, such as temperature difference, heat dissipation conditions, working fluid, etc.
Generally speaking, the power output of a thermoelectric power generation sheet is related to its surface area and its temperature difference. For small area thermoelectric power generation sheets, such as 30mm × 30mm products, the actual output power can reach about 5W. If a larger area thermoelectric power generation chip is used , such as a 40mm × 40mm product, the output power can reach about 11W.
However, it should be noted that the power generation capacity of the production sheets of Thermoelectric energy is also affected by other factors, such as heat dissipation conditions, working fluid, etc. If the conditions of dissthermal pation are not good or if the working fluid is incorrectly selected, the efficiency of power generation may be reduced. Therefore, in practical applications, it is necessary to select appropriate thermoelectric power generation sheets according to the specific environment and usage conditions to achieve the best power generation effect.
There is in principle no problem, but the efficiency should not exceed 0.1%, maybe even lower. How can we understand this effectiveness? Let's say your fire comes from a natural gas stove. If the natural gas consumed by this thermoelectric power generation system to produce 1 watt hour of electricity is used in a power plant that currently uses natural gas to generate electricity, then the power plant can use that natural gas to produce hundreds of watt hours of electricity.
