Thermoelectric generators size

In summary, the size of thermoelectric generators can vary greatly depending on their intended use and power output, ranging from small handheld devices to larger units that can be several feet in length. The size of a thermoelectric generator can affect its efficiency, with larger generators generally having a higher efficiency due to the ability to accommodate more materials and a larger temperature difference. Thermoelectric generators can be scaled up or down in size, but this may affect their efficiency and power output. There is no specific minimum size for a thermoelectric generator to be effective, but smaller generators may have lower efficiency and power output. The size of a thermoelectric generator can be limited by factors such as cost, materials availability, and practicality, as well

it's a simple question:
is there any limitation to the size of an thermoelectric generator module?
is there any minimum thickness?
thank you in advance

Actually it is not a simple question... There are a number of values that scale with size, and at the far ends there are physical constraints like atomic layers or gravity. When you make Peltier elements small they become very hard to manufacture. These guys probably make the smallest Peltier generators out there: http://www.micropelt.com/products/products.php For those the thickness is dominated by the silicon substrate.
 

1. What is the typical size range for thermoelectric generators?

The size of thermoelectric generators can vary greatly depending on their intended use and power output. However, most commercial thermoelectric generators range from small, handheld devices to larger units that can be several feet in length.

2. How does the size of a thermoelectric generator affect its efficiency?

The size of a thermoelectric generator can have a significant impact on its efficiency. Generally, larger generators have a higher efficiency as they are able to accommodate more thermoelectric materials and have a larger temperature difference between the hot and cold sides.

3. Can thermoelectric generators be scaled up or down in size?

Yes, thermoelectric generators can be scaled up or down in size depending on the desired application. However, the efficiency and power output may be affected by the size change.

4. Is there a minimum size for a thermoelectric generator to be effective?

There is no specific minimum size for a thermoelectric generator to be effective. However, smaller generators may have a lower efficiency and produce less power compared to larger ones.

5. Are there any limitations to the size of a thermoelectric generator?

The size of a thermoelectric generator can be limited by factors such as cost, materials availability, and practicality. Additionally, as the size increases, the weight and complexity of the generator may also increase, making it less suitable for certain applications.
