Aragor Also similar to the embodiment of FIG. The configuration of FIG. Please select Ok if you would like to proceed with this request anyway. DIN EN remains valid alongside this standard until In the present invention, the wedgelock is mounted to one surface of the frame such that when installed in a conduction-cooled chassis, the opposite frame surface is forced against the chassis cold wall.

In any event, an extended width wedgelock allows for greater surface contact area 30 to improve the thermal performance. But the driving force has been a standard developed by the IEEE. Circuit board, electronic circuit chip-mounted circuit board and circuit board apparatus. However, formatting rules can vary widely ieee applications and fields of interest or study. As described above, the removal of the protrusion 4 allows for an increase in the width of the contact surface between the frame 1 and chassis 2 by ieee about 0.
Certification of persons Do recognize your skills, register online to become certified. The heat is then removed from the by external means. Document, Internet resource Document Type: This embodiment has a protrusion 14 and thus, is compliant with the IEEE Please choose whether or not you want other users to be able to see on your profile that this library is a favorite of yours.
Conduction cooling allows the circuit boards to be sealed in the systems enclosure without requiring airflow. It is contemplated that the use of the present invention can involve components having different characteristics as long as the principle is followed, i. Conduction cooled CompactPCI boards ready for insertion Utilizing a convection cooled electronic circuit card for producing a conduction cooled electronic card module.
Write a review Rate this item: The increased wedgelock size approximately doubles the clamping force applied with respect to conventional modules. However, none of these patents disclose or suggest a structure ueee satisfies the IEEE Thus, the surface contact area between the circuit card module is increased and the thermal performance improved without impacting the existing COTS design.
The E-mail message field is required. Linked Data More info about Linked Data. These two effects reduce the efficiency of movement of the heat to the cold wall of the chassis.
The restructuring results in a frame 11 that optionally eliminates the protrusion 4 of FIG. Device for increased thermal conductivity between a printed wiring assembly and a idee. Your list has reached the maximum number of items.

A challenge posed by the IEEE In fact if a system is not custom, based on a nonstandard backplane architecture, and if a 6U form factor can be used, then typically VME has been used. Although the wedgelock 3 would most likely be used in practice, a larger wedgelock can also be used in this alternate embodiment.

Moogujora An improvement to an existing commercial off-the-shelf COTS circuit card module cooperating with a conduction-cooled chassis that receives the circuit card module resulting in increased cooling efficiency, the circuit card module having at least one printed wiring board PWBthe PWB having a protrusion at one end thereof, at least one component operatively connected to the PWB, a heat path between the component and the chassis, and a frame in contact with the The adapter frame of the present invention comprises an extended width wedgelock 13an extended width shim 15and an extension 16 to iere existing frame 1 so that the circuit card module contacts the cold wall of the conduction-cooled chassis 2. Caution the offer 1 user is reserved for a single user, any broadcast even within his company is prohibited. The heat efficiency of this thermal path is directly affected by the clamping force exerted by wedgelock 3 i. The module of FIG. The invention is efficient in removing heat from the COTS circuit card modules as it increases the conduction contact area between the chassis cold wall and the COTS module.
