A thermoelectric generator converts heat directly into electricity. As heat moves from a gas burner through a thermoelectric module, it causes an electrical current to flow.The heart of a thermoelectric generator is a hermetically sealed thermoelectric module (thermopile) which contains an array of lead-tin-telluride semiconductor elements.
This durable module provides a chemically stable environment for the thermoelectric materials which ensures a long service life. On one side of the thermopile, a gas burner is installed, while the opposite side is kept cool by aluminium cooling fins or a heat pipe assembly. An operating generator maintains a temperature of approximately 540 C on the hot side and 140 C on the cold side. The heat flow through the thermopile creates steady DC electricity with no moving parts.
