Thermoelectric power converter support structure
View Patent ↗An apparatus is provided and includes a reactor core, a boom and a shield assembly supportively interposed between the reactor core and the boom, a heat pipe disposed in thermal communication with the reactor core, a thermoelectric power converter operably coupled to the heat pipe, struts supportively coupled to the heat pipe at opposite ends of the power converter and hinge joints to rotatably couple the struts to the boom, at least one of the hinge joints being spring-loaded.
1. An apparatus, comprising:
a reactor core, a boom and a shield assembly supportively interposed between the reactor core and the boom;
a heat pipe disposed in thermal communication with the reactor core;
a thermoelectric power converter operably coupled to the heat pipe;
struts supportively coupled to the heat pipe at opposite ends of the power converter; and
hinge joints to rotatably couple the struts to the boom, at least one of the hinge joints being spring-loaded.
2. The apparatus according to claim 1 , wherein the at least one spring loaded hinge joint biases the struts to resist rotation due to thermal expansion of the heat pipe, the apparatus further comprising an end stop to limit the rotation.
3. An apparatus, comprising:
a reactor core, a boom and a shield assembly supportively interposed between the reactor core and the boom;
a heat pipe disposed in thermal communication with the reactor core;
two or more thermoelectric power converters operably coupled to the heat pipe;
three or more struts supportively coupled to the heat pipe at opposite ends of each of the power converters; and
hinge joints to rotatably couple the struts to the boom, at least one of the hinge joints being spring loaded.
4. The apparatus according to claim 3 , wherein the heat pipe is plural in number and further comprising lateral support structures supportively coupled to adjacent struts.
5. The apparatus according to claim 3 , wherein four power converters are operably coupled to the heat pipe and five struts are supportively coupled to the heat pipe at the opposite ends of each of the power converters.
6. The apparatus according to claim 3 , wherein each strut comprises:
an elongate member; and
a flanged interface for receiving the heat pipe therethrough at an end of the elongate member.
7. The apparatus according to claim 6 , wherein the elongate member comprises titanium.
8. The apparatus according to claim 6 , wherein the flanged interface is tightly fit about the heat pipe.
9. The apparatus according to claim 6 , wherein the flanged interface has a split cap bolted construction.
10. The apparatus according to claim 6 , wherein the flanged interface comprises a titanium ball pivot joint with a zircon insert.
11. The apparatus according to claim 3 , wherein the at least one spring loaded hinge joint biases the struts to resist rotation.
12. The apparatus according to claim 11 , further comprising an end stop to limit the rotation.
13. A thermoelectric power converter support structure for an apparatus including a reactor core, a boom, a shield assembly supportively interposed between the reactor core and the boom and a heat pipe disposed in thermal communication with the reactor core on which two or more thermoelectric power converters are operably coupled, the support structure comprising:
three or more struts supportively coupled to the heat pipe at opposite ends of each of the power converters; and
hinge joints to rotatably couple the struts to the boom; at least one of the struts being spring loaded.
14. The support structure according to claim 13 , wherein four power converters are operably coupled to the heat pipe and five struts are supportively coupled to the heat pipe at the opposite ends of each of the power converters.
15. The support structure according to claim 13 , wherein each strut comprises:
an elongate member; and
a flanged interface for receiving the heat pipe therethrough at an end of the elongate member.
16. The support structure according to claim 15 , wherein the elongate member comprises titanium.
17. The support structure according to claim 15 , wherein the flanged interface is tightly fit about the heat pipe.
18. The support structure according to claim 15 , wherein the flanged interface has a split cap bolted construction which captures a titanium ball pivot joint with a zircon insert.
19. The support structure according to claim 13 , wherein the spring loaded hinge joint biases the struts to resist rotation.
20. The support structure according to claim 19 , further comprising an end stop to limit the rotation.
