Thermal conduction to a cylindrical shaft
A canister system having a cylindrical housing and a modular electronic rack system disposed within the cylindrical housing. The modular electronic rack system includes a thermal contact member that is in at least selective physical contact with an interior surface of the cylindrical housing to permit conductive heat transfer there through. An input/output device extends along at least a portion of the modular electronic rack system and includes a power input and a signal output electrically coupled thereto. A plurality of electronic slots disposed at a position generally along the modular electronic rack system is provided.
1. A canister system comprising:
a cylindrical housing;
a modular electronic rack system disposed within said cylindrical housing, said modular electronic rack system having a plurality of generally parallel, thermally conductive, ribs arranged generally perpendicularly to a central axis of the cylindrical housing a housing and extending away from a backplane in an arcuate manner, said plurality of ribs being in physical contact with an interior surface of said cylindrical housing to permit conductive heat transfer there through, said plurality of ribs supported by and extending away from the backplane at a first end and the backplane being arranged generally parallel to the central axis of the cylindrical housing;
an input/output board extending along at least a portion of said modular electronic rack system, said input/output board having a power input and a signal output electrically coupled thereto; and
a plurality of generally planar, parallel electronic slots defined by adjacent and opposite pairs of ribs in proximity to a second end of the ribs opposite the backplane and arranged perpendicularly to the backplane, each slot configured to receive a generally planar electronic card arranged perpendicularly to the backplane and inserted into the slot for electronic coupling to a corresponding slot in the backplane.
2. The canister system according to claim 1 wherein said plurality of electronic slots is configured to physically and operably receive an electronic card therein, each of said plurality of electronic slots being electrically connected to said input/output board to establish electrical communication between the electronic card and said input/output board.
3. The canister system according to claim 1 , wherein
physical contact between said plurality of ribs and said interior surface of said cylindrical housing is adjustable to selectively vary the conductive heat transfer.
4. The canister system according to claim 3 further comprising a wedge cam device operable to selectively exert a driving force to urge said plurality of ribs into said physical contact with said interior surface.
5. A canister system comprising:
a cylindrical housing;
a modular electronic rack system disposed within said cylindrical housing, said modular electronic rack system having a plurality of generally parallel rib members arranged generally perpendicularly to a central axis of the cylindrical housing and extending away from a backplane in an arcuate manner, said plurality of rib members being in physical contact at a variable force with an interior surface of said cylindrical housing to permit variable conductive heat transfer there through, said plurality of rib members supported by and extending away from a planar backplane at a first end the backplane being arranged generally parallel to the central axis of the cylindrical housing;
an input/output board extending along at least a portion of said modular electronic rack system, said input/output board having a power input and a signal output electrically coupled thereto;
a plurality of generally planar, parallel electronic slots defined by adjacent pairs of ribs in proximity to a second end of the ribs opposite to the backplane and arranged perpendicularly to the backplane, each slot configured to receive a generally planar electronic card arranged perpendicularly to the backplane and inserted into the slot for electronic coupling to the backplane, wherein the plurality of parallel electronic slots is dispose at a position generally along said modular electronic rack system; and
said plurality of rib members being adjustable to selectively vary a force of said physical contact with said interior surface of said cylindrical housing.
6. The canister system according to claim 5 wherein said plurality of electronic slots is configured to physically and operably receive an electronic card therein, each of said plurality of electronic slots being electrically connected to said input/output board to establish electrical communication between the electronic card and said input/output board.
7. The canister system according to claim 5 further comprising a wedge cam device operable to selectively exert a driving force to urge said rib members into said physical contact with said interior surface.
8. The canister system according to claim 7 wherein said backplane has a longitudinal axis generally parallel to a longitudinal axis of said cylindrical housing.
