Direct contact cooling liquid embedded package for a central processor unit
ActiveUS20070177352A1Avoid a lotAvoid introducingSemiconductor/solid-state device detailsSolid-state devicesCouplingPackage design
A direct contact cooling liquid embedded package design for use with a computer central processor unit is suitable for thermal management of high heat dissipation electronic components such as server processors. The direct contact cooling liquid embedded packaged CPU has mechanical coupling and embedded plumbing that attaches to the board pumped liquid supply and direct contact cooling liquid of the heat-generating portion of the CPU. A direct contact cooling liquid embedded packaged CPU removes higher levels of heat directly from the core of the processors by convective cooling. Cooling liquid is introduced into the package of the server CPU by mechanically attaching the CPU to the board through a socket interconnect. Pins of the socket serve to provide electrical connection between the board and the CPU, while a few pins are designed for the purpose of inlet and outletting cooling liquid into and out of the CPU package.

The invention provides a halting method and system for a fan in an extreme state, and relates to the field of fan control. The method provided by the invention comprises the steps that a paddle collecton speed changing manner is adopted, before gust halt, firstly, a pitch angle of a wind wheel is adjusted at a high paddle collecton speed, so as to avoid the problem that the wind wheel overspeeds; and then, the pitch angle of the wind wheel is adjusted at a low paddle collecton speed, so as to avoid the problem that the overall mechanical load of the fan is too large. Through the adoption of the control method, the fan can avoid the situation that the fan overspeeds and flies and the situation that the fan structure breaks due to the fact that the mechanical load of the fan is too large at the same time, and the safety of the fan during the gust halt process is improved.

A method produces a flat semi-finished product from a fiber composite material that contains individual carbon fibers, carbon fiber bundles, or a mixture thereof in a defined anisotropic fiber orientation and a thermoplastic matrix material. The anisotropy of the carbon fibers is created in a carding process using the high orientability of admixed non-carbon textile fibers, at least some of the non-carbon textile fibers being thermoplastic, and the carbon fibers having been isolated from waste or used parts. The flat fibrous web which is produced by a carding process and which has a specific orientation of the carbon fibers in the longitudinal direction is compressed into a sheet material under the effect of heat. This enables the use of carbon fibers, for example from production waste, as reinforcing fibers, whereby a less expensive raw material is provided and the carbon fibers are contained in the waste materials are recycled.
