Abstract

A power converter is provided and includes a heat collector surface, n- and p-legs formed of n- and p-type thermoelectric materials, respectively, which are each disposed in thermal communication with the heat collector surface, parallel electric busses electrically coupled to the n- and p-legs and a housing, which is electrically decoupled from the busses, to support the heat collector surface at a predefined distance from a heat pipe.

Claims (8)

1. A space based heat pipe cooled reactor, comprising:

a reactor core;

a heat pipe disposed in a vacuum, the heat pipe in thermal communication with the reactor core;

a power converter having

a plurality of heat collector surfaces arranged about the heat pipe to form a radiant heat receiving cavity, wherein the vacuum is between the heat pipe and the plurality of heat collector surfaces,

n- and p-legs formed of n- and p-type thermoelectric materials, respectively, which are each disposed in thermal communication with the heat collector surface,

parallel electric busses electrically coupled to the n- and p-legs and

a housing, which is electrically decoupled from the busses, configured to support the heat collector surfaces at a predefined distance from a heat pipe.
