Abstract: An enclosure (10) for protecting and dissipating heat from electronic equipment such as telecommunications repeater cards (12). The enclosure includes: exterior walls defining a substantially enclosed chamber (14); at least one shelf (16) positioned within the chamber for holding a plurality of repeater cards, the shelf including spaced apart top and bottom walls (60, 62) configured for receiving the cards therebetween and for making direct contact with the cards to allow conduction of heat to the top and bottom walls from the cards; a plurality of elongated heat pipes (84) each having a first, proximal end (84a) coupled with the top or bottom wall for conducting heat to the heat pipe from the top or bottom wall, the heat pipes also each having a second, distal end (84b); and at least one fin (86) coupled with the second, distal end of each of the heat pipes for conducting heat to the fin from the heat pipes so that the heat may be convected from the fin to ambient air in the chamber.

Abstract: An enclosure (10) for protecting and dissipating heat from telecommunications repeaters (12). The enclosure includes a plurality of card-receiving sleeves (14) for receiving repeater cards; at least one heat sink manifold (16) in contact with the sleeves for conducting heat from the sleeves; at least one outer panel (28) in contact with the heat sink manifold for conducting heat from the manifold; a removable cover (40) configured for sliding over the outer panel to protect the cards from exposure to the elements; and at least one biasing mechanism (112) operably coupled with the outer panel for biasing the outer panel into physical contact with the cover when the cover is placed thereover to improve conduction of heat from the outer panel to the cover.
