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.

This invention relates to a tool intended for chip removing machining together with a cutting insert therefor. The cutting insert is formed having a connecting surface or serrations that comrises ridges (11) and intermediate grooves. The flanks (18) which delimit the ridge (11) have a convexly curved surface (28), the contact point of which to a co-operating flank (25) of a co-operating ridge consists of a line (G), which extends axially along the length extension of the flank and is situated in an area approximately halfway between on teh one hand an outer transition (19) between the flank (18) and an apex (17) and on the other hand an inner transition (23) between the flank and a groove bottom. The convexley curved surface extends inwards as well as outwards from said contact line (G), in order to guarantee that practical contact between the flanks of the co-operating ridges is attained via surface contact at an indifferent place between the outer and inner limiting edges (29, 30) of the curved surface.

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.

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.
