Embodiments of the disclosure provide cooling systems and cooling methods for isolating temperature fluctuation in an electronics enclosure. Embodiments of the disclosure provide effective cooling of high power temperature fluctuating components and a stable reference temperature for temperature sensitive components included in a single electronics enclosure. A disclosed multiple path cooling system includes a first path for cooling power variable components and a second path to maintain stable temperature cooling for temperature sensitive components.

Isolating temperature fluctuation in an electronics enclosure

A latch assembly includes a lever arm affixed to a latch pivot point of rotation with a cam having a connecting slot. A load mechanism is configured to apply a force on the latch pivot point to retain the lever arm in a first position. The load mechanism is tuned to apply the force along a tolerance range of operation of the latch assembly.

Tunable tolerance stack-compliant latching

A system, an article of manufacture, and a method are disclosed. The system includes a set of components in an enclosure. The set of components includes electronic devices and airflow moving components configured to maintain airflow across the electronic devices from a front plenum of the enclosure to a rear plenum of the enclosure and direct air from the rear plenum through the first heat exchanger. The set of components also includes a first heat exchanger configured to circulate a cooling liquid and a second heat exchanger configured to maintain a constant temperature of the cooling liquid, wherein the constant temperature is a temperature of the cooling liquid within a threshold distance from a selected temperature.

Constant temperature closed-loop airflow containment

A thermal interface material (TIM) structure for directing heat in a three-dimensional space including a TIM sheet. The TIM sheet includes a lower portion along a lower plane; a first side portion along a first side plane; a first upper portion along an upper plane; a first fold between the lower portion and the first side portion positioning the first side portion substantially perpendicular to the lower portion; and a second fold between the first side portion and the first upper portion positioning the first upper portion substantially perpendicular to the first side portion and substantially parallel to the lower portion.

Thermal interface material structures for directing heat in a three-dimensional space

A fixture to facilitate fabrication of a heat sink includes a base plate to support a lower section of the heat sink, and multiple registration pins extending from the base plate. A platen is provided over a heat transfer element (HTE) of the heat sink, with the platen including slip fit regions to slip fit around respective registration pins, and with the lower section and HTE disposed between the base plate and the platen, and forming a fixture stack segment aligned with an active region of the cold plate. A load plate is provided which includes slip fit regions configured to slip fit around corresponding registration pins with the load plate disposed over the fixture stack segment. The load plate includes a single load pin centrally disposed to apply a load to the fixture stack segment and facilitate bonding the lower section and HTE together.

Fixture facilitating heat sink fabrication

A method and apparatuses are provided for removing a cold plate assembly from an electronics enclosure. The apparatus includes a chassis configured to be placed on the electronics housing in an aligned manner. The chassis includes a plurality of brackets disposed on the chassis. The respective ones of the plurality of brackets are configured to be attached to respective electrical components in the electronics housing. The respective ones of the plurality of brackets are also configured to be disposed on the chassis at locations corresponding to the locations of the respective electrical components within the electronics housing when the chassis is aligned with the electronics housing. The respective ones of the plurality of brackets are also configured to selectively movable between a first orientation and a second orientation. The respective brackets are closer to the respective electrical components in the first orientation than in the second orientation.

Installation tool for flexible elements

A cold plate, an electronic assembly including a cold plate, and a method for forming a cold plate are provided. The cold plate includes an interface plate and an opposing plate that form a plenum. The cold plate includes a plurality of active areas arranged for alignment over respective heat generating portions of an electronic assembly, and non-active areas between the active areas. A cooling fluid flows through the plenum. The plenum, at the non-active areas, has a reduced width and/or reduced height relative to the plenum at the active areas. The reduced width and/or height of the plenum, and exterior dimensions of cold plate, at the non-active areas allow the non-active areas to flex to accommodate surface variations of the electronics assembly. The reduced width and/or height non-active areas can be specifically shaped to fit between physical features of the electronics assembly.

Cold plate

A shelf device facilitates access to electronic modules within an enclosure having multiple vertically stacked levels of module storage locations. A pair of support arms each have an attachment structure on a distal portion of the support arm that is designed to attach to a first one of the vertically stacked levels. A guide rail extends from the distal portion of the support arm toward a proximal portion of the support arm. A cross brace structure is configured to pivotally attach to distal portions of the pair of support arms and a proximal portion of a first one of the support arms. A pair of vertical braces are each configured to pivotally attach to a respective one of the pair of support arms and having a detachable connection structure that is designed to attach to a second one of the vertically stacked levels.

Service shelf for electronic cabinet

Embodiments of the present invention provide for non interruptive fluid cooling of an electronic enclosure. One or more electronic component packages may be removable from a circuit card having a fluid flow system. When installed, the electronic component packages are coincident to and in a thermal relationship with the fluid flow system. If a particular electronic component package becomes non-functional, it may be removed from the electronic enclosure without affecting either the fluid flow system or other neighboring electronic component packages.

Cooling system for electronic components

Apparatuses for compressing a thermal interface material between a heat generating electrical component and a cooling electrical component are provided. Embodiments include a draw rod coupled at one end to the cooling electrical component, the draw rod passing through the heat generating electrical component; wherein the draw rod includes a pin on the end opposite the end coupled to the cooling electrical component; and a rotatable latch coupled to the heat generating electrical component, the rotatable latch including a hook at one end; wherein when the rotatable latch is in an engaged position, the hook of the rotatable latch engages the pin of the draw rod such that the thermal interface material adhered to the heat generating component is coupled to the cooling electrical component.
