Abstract:
A system for designing a circuitry configuration of heat-exchanger units includes an interface to acquire design parameters the heat-exchanger units, a memory to store computer-executable programs including a relaxed decision diagram formation module, and a processor, in connection with the memory, configured to perform the computer-executable programs. The computer-executable programs include steps of providing a configuration of the heat-exchanger units, providing the design parameters of the heat-exchanger units acquired via the interface, generating a relaxed decision diagram based on the design parameters, creating constraints with respect to connections of the heat-exchanger units according to the relaxed decision diagram, and generating feasible configurations of the heat-exchanger units by a mixed-integer-programing method using the constraints.
Abstract:
An electrically driven pump is provided, which includes an impeller. The impeller includes an upper plate, blades and a lower plate. The blades are formed on a lower surface of the upper plate, the blades include first blades and second blades, and a length of each of the first blades is greater than a length of each of the second blades. The first blades are uniformly distributed along a circumference of the upper plate. The first blades and the second blades are distributed alternately in the circumferential direction. The first blades each include a first head portion and a first tail portion, the second blade includes a second head portion and a second tail portion, and the first tail portion and the second tail portion are aligned with outer edge of the upper plate. The impeller arranged in such manner facilitates the improvement of hydraulic efficiency and lift.
Abstract:
A heat sink fastening device includes an operating member and a retaining member axially extended through the operating member and associated with the latter via a pivot shaft. The operating member includes a cylindrical cam portion, which has an elastic element received therein to provide the cam portion with an elastic force. The cam portion has an upper end formed into a pair of cam surfaces, on which the pivot shaft is rested. The operating member can be horizontally rotated about an axis thereof. When the operating member is rotated, the cam surfaces rotate and cause the pivot shaft to move from a higher to a lower position on the cam surfaces or vice versa, so that the retaining member associated with the operating member via the pivot shaft is brought by the pivot shaft to axially move downward to a released position or upward to a fastened position.

The at least one universal fastener assembly is orthogonally assembled through the mounting bracket. The liquid-cooling heat exchange apparatus includes a first liquid-cooling heat exchange apparatus having a first waterblock set or a second liquid-cooling heat exchange apparatus having a second waterblock set. The first waterblock set has a first block thickness, and the second waterblock set has a second block thickness. The substrate or the electronic component includes receiving portions having a fastened thickness. A thickness of the second block thickness and the fastened thickness is greater than a thickness of the first block thickness and the fastened thickness.
Abstract:
The first and second media are coupled via evanescent waves generated by surface phonon polaritons thermally excited on surfaces of the first and second media. First and second media made of the same material are disposed with a gap formed between for cutting off thermal conduction and the heat transfer between them is performed via the thermally excited evanescent waves. A third medium is provided on a surface of the first medium on a side toward the second medium. Heat flux flows from the second medium to the first medium in a first state wherein the second medium has a first temperature TH and the first medium has a second temperature TL lower than the TH differ in intensity from heat flux which flows from the first to the second medium in a second state wherein the first medium has the TH and the second medium has the TL.
