A fan fixation structure for a server is provided, comprising a first scarfing portion disposed on the server, a first connection portion disposed on the server, a second scarfing portion disposed at a rear end of the fan and may be scarfed to the first scarfing portion, a first extension member disposed at a front end of the fan and has a proper elasticity, a second connection portion formed integrally with the first extension member and movable back and forth with the extension member between a first position and a second position and capable of locking with the first connection portion at the first position. As such, a user may rapidly detach or install each fan from or into the server separately without any tool.

A central processing unit (CPU) that has a die on one side and a radiator mounting onto the side of the CPU where the die is located includes a protection wall surrounding the die. The protection wall prevents the radiator from directly hitting the CPU during mounting thereby protects the CPU from being damaged and facilitates installation of the radiator.

A plate evaporator includes a first thermal conductive element and a second thermal conducive element. The rim of the first thermal conductive element is formed with a first joining portion. The second thermal conductive element is like a cap having a second joining portion at the rim and correspondent to the first joining portion of the first thermal conductive element. Therefore, upon assembling the two thermal conductive elements, the first and second joining portions are engaged. When brazing, only the joining portions are at high temperature. The temperature rise does not apply to the whole thermal conductive elements and does not influence the strength of the structure.

A miniaturized fan module can be accommodated in an electronic system (such as a server) to provide heat dissipation. The miniaturized fan module has a smaller structural size than that of a conventional fan module, such that a larger bump-preventing buffer space between the miniaturized fan module and a framework of the server is provided for preventing the fan module from bumping against the server framework due to vibration generated in practical operation, without degrading a heat dissipating effect and structural strength of the fan module.

A serial fan set and rotation speed-matching curve generation method thereof are provided. The serial fan set comprises a rotation speed control module, a first fan and a second fan, in which the rotation speed control module is used to receive the power signal and produce the rotation speed driving signal corresponding to the power signal in accordance with the relations of the rotation speed-matching curve, so that the first fan and the second fan are operated at the matching rotation speed, thus producing the optimum operation efficiency and achieving the purpose of controlling the serial fan set.

A radiation apparatus for dispersing heat energy generated by a heat-generating element includes a first and a second board chambers, a condenser tube, an evaporation tube and working fluid. The condenser tube and the evaporation tube have respectively two ends located on the first and the second board chambers. The first and second board chambers, condenser tube and evaporation tube jointly form a closed space to contain the working fluid. The working fluid in the evaporation tube absorbs heat energy from the heat-generating element and vaporizes to flow through the first board chamber to the condenser tube. In the condenser tube, the heat energy previously absorbed in vaporized working fluid is dispersed and the working fluid is condensed to become liquid flowing through the second board chamber to the evaporation tube to proceed another heat dissipation cycle. Thus heat dissipation efficiency may increase in the limited space of the server.

A heat sink includes a base, a set of fins mounted to the base and a plurality of fixing portions, wherein the fixing portions extend from a surface of the base and the set of fins are mounted on an opposite surface of the base. The heat sink is secured to a printed circuit board with at least one heat generating component through the fixing portion of the base. The heat sink is improved by forming one or more slots at lateral sides of the base such that one or more deformable portions can be defined on the base. Thus, the deformable length of the base is increased and the heat stress is relaxed.

A heat sink includes a base, a set of fins and at least an elastic fixing member mounted on a surface of the base. The elastic fixing member includes an elastic sheet mounted on the base, a supporting portion disposed on the elastic sheet and a fixing portion disposed on the supporting portion. The heat sink is secured to a printed circuit board through the fixing portion of the elastic fixing member, with the base of the heat sink being in direct contact with a heat generating component mounted on the printed circuit board. The distance between the base of the heat sink and the heat generating component can be controlled so as to even pressure on the heat generating component and efficiently decrease heat stress.
