Automated method and apparatus for processor thermal validation

A method and corresponding software for automatically validating a computer platform thermal solution. An application program is employed to selectively execute thermal stress code to cause the platform's processor to dissipate an amount of power corresponding to a predetermined value, such as a thermal design power dissipation value specified by the processor's manufacturer. In one embodiment, tests are performed while operating at this power dissipation level to determine if a thermal overload condition exists, which may be determined by the processor's temperature, an indication that the processor is throttled, or a signal provided by the processor indicating the processor has detected a thermal overload condition. In another embodiment, a thermal resistance value is calculated based on the processor power dissipation, the temperature of the processor, and the ambient temperature of the test environment. In one embodiment the entire validation process is automatically performed by the application program without requiring any extraneous test equipment or temperature probes.

Phase-change heat reservoir device for transient thermal management

A heat transfer system is presented for managing thermal transients, thus providing engineers greater flexibility in designing thermal solutions for applications subject to transient heat-generation. A heat reservoir device for managing a heat input subject to transient conditions includes a heat transfer subsystem having a first end and a second end, where the first end is thermally coupled to the heat input; a heat storage subsystem coupled to the second end of the heat transfer subsystem, where the heat storage subsystem comprises a phase change material responsive to the transient conditions. The excess heat load during transient operation is temporarily absorbed by the latent heat of fusion when the phase change material changes its phase from solid to liquid. Subsequently, the absorbed heat can be released back to the ambient via a heat rejection subsystem. This allows engineers to design smaller heat sinks capable of accommodating given transient conditions. This results in heat sinks which are lower cost and smaller size, or which reduce the requirement to provide higher airflow, thereby also decreasing cost and noise, and increasing reliability.

Apparatus and method for precision thermal processing of a body

The invention pertains to apparatus and method for precision thermal processing of a body. An energy beam emanating from an energy beam source is scanned across the surface of the body, creating heat input through a moving spot on the surface of said body. By means described herein to condition the spot shape and flux profile, the flux profile within the spot is configured to approximate a thermal solution obtained by solving a boundary condition of the third kind imposed upon the moving spot associated with the beam as it is scanned across the body. In this manner a predetermined surface temperature profile is imposed on the surface of the body within a moving, locally heated spot of predetermined shape and size.Potential uses include any application which would benefit from the ability to apply a prescribed uniform or variable thermal process to the surface of a body, thus including but not limited to thermal processing of inorganic materials, such as metals and ceramics, and thermal processing of polymeric or organic materials or tissues. Exemplary desired outcomes range from an improvement of surface properties, such as hardness or wear resistance, to the fabrication of a component through an additive manufacturing process.

Sliding thermal contact for pluggable optic modules

Present thermal solutions to conduct heat from pluggable optical modules into heat sinks use a metal heat sink attached with a spring clip. The interface between the pluggable module and the heat sink is simple metal-on-metal contact, which is inherently a poor thermal interface and limits heat dissipation from the optical module. Heat dissipation from pluggable optical modules is enhanced by the application of thermally conductive fibers, such as an advanced carbon nanotube velvet. The solution improves heat dissipation while preserving the removable nature of the optical modules.

Thermal management of systems having localized regions of elevated heat flux

A thermal management system (300) includes a first heat transfer body (330) for providing a opposing heat flux to at least one localized region of elevated heat flux residing in adjacency to a region of lesser flux, such as on a surface (315a) of a circuit die (315) due to a integrated circuit hot-spot (310). A contact (320, 321 962a, 962b, 970a, 970b or 950) defines a thermal conduction path for the opposing flux. A second heat transfer body (350) is in a heat transport relationship with the first heat transfer boy (330) and a second heat transport relationship with the region of lesser heat flux. In such arrangement, each region of heat flux is provided a thermal solution commensurate with the level of heat flux in the region. For example, the opposing heat flux of an active first heat transfer body (330), such as a thermoelectric cooler, may be provided at the hot-spot (310), while at the same time the lesser heat flux is absorbed by a passive second heat transfer body (350), such as a heat spreader.

Unified retention mechanism for CPU/socket Loading and thermal solution attach

An apparatus for removably retaining an IC package in engagement with a socket such that the contacts of both the IC package and the socket are properly engaged is disclosed. Specifically, a universal retention mechanism (URM) which may be fabricated in a diecast material, may comprise a retention frame to engage a socket. A load plate hinged to the retention frame may be caused to press the socket and IC package together through force selectively applied through the use of a load lever. In addition, the frame may contain features to attach a thermal solution (e.g. a heat sink or other cooling device) directly to the frame thus eliminating the need to attach it directly to a motherboard or through a backplate.

Integrated Electrical and Thermal Solution for Inverter DC-Link Capacitor Packaging

An improved capacitor packaging solution is presented that incorporates both thermal and electrical considerations. A package can include capacitor elements electrically coupled to a bus bar, and a thermally enhanced isolation layer between the bus bar and a case. The isolation layer can be provided adjacent a case base and sidewall portions. The bus bar can be disposed adjacent the isolation layer and be configured to extend along the package side and along the package length below the capacitor elements to provide an extended path for heat dissipation from the bus bar prior to its contact with capacitor elements. The enhanced isolation layer is configured to conduct heat away from the bus bar to the case to avoid the hotspot temperature of the capacitor. Reduced capacitor temperature allows use of smaller, cheaper capacitors, reducing inverter costs without compromising performance.
