摘要:
An interface is formed by pressing a patterned first surface and a second surface together, with a particle-loaded interface material in between. The first surface is fabricated with a pattern of channels designed to redistribute the velocity gradients that occur in the interface material during interface formation in order to control the arrangement, orientation and concentration of particles at the end of the interface formation. The concept finds application in thermal interfaces and controlled placement of nano and micro particles and biological molecules.

A stress release thermal interface is provided for preventing the building up of stress between chip and heat sink surfaces in a multi-chip module (MCM) while maintaining reliable thermal and mechanical contact. The interface achieves enhanced thermal conduction by using flexible, interlocking posts attached to the surfaces of the chip and the heat sink.

A cooling device has a large number of closely spaced impinging jets, adjacent an impingement gap, with parallel return paths for supplying coolant flow for the impinging jets with the least possible pressure drop using an interdigitated, branched hierarchical manifold. Surface enhancement features spanning the impingement gap form U-shaped microchannels between single impinging jets and single outlets.
摘要:
A flexible, self-contained active multi-phase heat spreader apparatus for cooling electronic components, the heat spreader having fluid sealed between two plates and a pumping mechanism to actuate multi-phase flow of the fluid. Thermal energy from an electronic component in contact with the heat spreader is dissipated from a core region via the working fluid to the entire heat spreader, and then to a heat sink. Surface enhancement features located between the two plates aid transfer of thermal energy from a first metal plate into the fluid.

The present invention provides a thermal interface with a first and a second face that are in contact to each other by a thermal conducting material. A first face includes grooves that are at least partly filled with the thermal conducting material, wherein at least two types of grooves are arranged, namely first grooves having a larger width than second grooves. The first face comprises an array with protrusions that are confined by the second grooves, the array being divided by the first grooves into sub-arrays.
摘要:
A coolant pumping system for a mobile electronic system includes a coolant reservoir containing a coolant, a heat exchanger member fluidly connected to the coolant reservoir, and a mass moveably mounted to the mobile electronic system. The mass is moved along at least one axis in response to at least one of accelerations and orientation changes of the mobile electronic system. The coolant system further includes a force transfer member operatively connected between the mass and the coolant reservoir. The force transfer member urges the coolant from the coolant reservoir through the heat exchanger member in response to movements of the mass. A gear member is operatively connected between the mass and the force transfer member.
