Abstract
A circuit element is produced in a circuit, and a thermoelectric cooling element comprising two dissimilar metals is thermally coupled to the circuit element for cooling the circuit element. A source is provided for applying a driving current to the circuit element. The circuit is arranged such that the driving current passes to the thermoelectric cooling element as an operating current thereof.
Claims6
A thermoelectric cooling system comprising:
- a circuit element;
- and
- a thermoelectric cooling element including
- a metal plate directly mounted on one surface of the circuit element,
- a semiconductor mounted on the metal plate, and
- a heat sink mounted on the semiconductor,
- wherein said circuit element is thermally connected to said thermoelectric cooling element, and said circuit element and said thermoelectric cooling element being arranged such that at least part of a driving current, which is applied to said circuit element, flows passing through said thermoelectric cooling element, wherein said thermoelectric cooling element is operated to cool said circuit element.
