An electronics rack comprising a first cage, a first heat sink positioned at a rear and in thermal communication with the first cage, a second cage positioned above the first cage, and a second heat sink in thermal communication with the second cage. In another aspect, the present invention provides an electronics rack comprising a frame, a cage, a heat sink positioned at a rear of the frame, and a compliant thermal collector operatively positioned between the cage and the heat sink. The compliant thermal collector can comprise a heat pipe having a non-linear shape that facilitates flexing of the heat pipe to change the length of the thermal collector. The thermal collector advantageously includes a plurality of heat pipes and a contact bar coupling the plurality of heat pipes. Preferably, the rack further includes an adjusting mechanism (e.g., threaded rods) for adjusting a position of the contact bar.

Electronics rack with compliant heat pipe

A heat transfer device is provided for conducting heat from a heat source. The heat transfer device generally includes an evaporator for generating a vapor, a condenser in fluid communication with the evaporator, and a vapor flow restrictor interposed between the evaporator and the condenser, wherein the vapor flow restrictor can increase vapor pressure in at least a portion of the evaporator relative to vapor pressure in the condenser.

Variable-conductance heat transfer device

An electronics rack comprising a frame, a heat sink coupled to the frame, and a cage adapted to support an electronic component. The cage is movable between first and second positions toward and away from the heat sink. The rack further includes an eccentric cam operatively positioned between the frame and the cage and being rotatable to move the cage between the first and second positions. In one embodiment, the cage comprises a cooling brick movable toward and away from the heat sink when the cage moves between the first and second positions. The cooling brick can include a first heat pipe extending generally in a first direction and a second heat pipe extending generally in a second direction transverse to the first direction. For example, the first heat pipe can be embedded in a top plate and the second heat pipe can be embedded in a top cold rail.

Electronics rack with selective engagement of heat sink

A heat pipe for a cautery surgical instrument such as a surgical forceps including a pair of elongate arms joined at an end so as to provide for resilient compressible movement of the arms between a normally open position and a squeezed closed position. The heat pipe provides for conduction of heat away from an electrode tip, and comprises an evaporator portion having a first diameter and a condenser portion spaced away from the evaporator end, and that transitions from the first diameter to at least one smaller diameter section. A socket is disposed within each arm of the forceps and includes a longitudinal blind hole that is sized so as to releasably receive the smaller diameter section of the condenser portion, and a catch for engaging a portion of the arm.
