Function and Applications
To commute thermal energy into electrical energy directly and
for operation as heat pump. Also been used to demonstrate the
Seebeck effect and the Peltier effect.
Equipment and technical data
- Generator block consisting of two nickel coated copper plates
with hole for thermometer, between these, p- and n-conducting
silicon thermocouples, connected thermally parallel and
electrically in series.
- Two water containers with open sides, which are used as heat
reservoirs, are screwed to the generator block. They can be
exchanged for flow through heat exchanger or air cooler.
- Standard accessories: 2 open water containers (brass, nickel
coated); 2 rubber gaskets; 2 clamping jaws and 4 knurled
- Number of thermocouples: 142.
- Permanent operating temperature: approx. 100 °C.
- Interior resistance: 2.8 Ohm.
- Operation as thermo generator: output voltage at T = 40 °C:
approx. 2 V; efficiency at T = 40 °C: approx. 1%.
- Operation as heat pump: max. permanent current 6 A.
- Dimensions (mm): generator block: 24 × 80 × 126, water
container 28 × 70 × 94.
