Abstract
A thermally conductive feedthrough has a conductive member extending through a fiber-reinforced plastic plate. The feedthrough is sealed against leakage from one side of the plate to the other by placing the plate in local compression to seal it against the plate and/or by using small individual conductive members that minimize the effects of thermal expansion differences. The feedthrough can be used between vacuum and cryogenic liquids.
Claims3
A thermal feedthrough, comprising:
- a fiber-reinforced plastic plate having a first surface and a second surface, and further having a plate bore therethrough;
- and
- a plug sized to fit within the plate bore and affixed into the plate bore, the plug comprising:
- a length of a cured fiber-reinforced composite material wound onto a cylindrical nonmetallic form into a generally cylindrical, multiturn, jelly roll coil, with a cylindrical axis of the coil generally perpendicular to the surfaces of the plate, and
- at least two thermally conductive wires penetrating between the turns of the coil and through the length of the cylindrical coil generally parallel to the cylindrical axis of the coil.
