Thermoelectric battery, protected against shocks and accelerations

摘要

In a thermoelectric battery the heat source is suspended on the end of a thermoelectric unit, the other end of which is attached via a heat conducting mass to the casing. A resilient mounting permits resilient rocking of the thermoelectric unit to reduce stress on the unit in the event of shock or acceleration applied to the casing and spring fingers not normally in contact with the heat source or the thermoelectric unit are positioned to arrest the heat source if the assembly rocks more than a predetermined amount.
