摘要:
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 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 fan module for failure backup includes a flow guide structure and a first and a second fan disposed coaxially. The first and second fans are accommodated in the flow guide structure, and the flow guide structure has an air inlet and two vents respectively corresponding to the first and the second fan. The two vents respectively have a movable cover plate. The first and the second fan operate at a low speed in a normal state, such that the cover plate assumes an open state to provide a low speed air flow. When one of the fans fails to operate, the cover plate thereof assumes a closed state, and the other fan operates in a high speed to provide a high speed air flow, thereby achieving a purpose of failure backup.

A radiator structure includes a radiator frame, a radiator and a plurality of elastic latch members. The radiator frame is mounted onto a main board corresponding to an electronic element, and has a plurality of coupling sections and an opening corresponding to the electronic element and the surface of the electronic element exceeds its peripheral edges. The radiator is mounted on the radiator frame in contact with the surface of the electronic element, and has a plurality of latch sections corresponding to the coupling sections. The elastic latch member coupled on the latch section is bent to form a force applying section, a latch arm and a swinging arm. After the force applying section receives a force, the swinging arm coupled on the latch section is turned to enable the latch arm to latch on the coupling section thereby to anchor the radiator on the radiator frame to disperse heat.

A fan-driven heat dissipating device with an enhanced air blowing efficiency is provided, which is designed for use in conjunction with a casing of an electronic system, such as a server, for providing the server with a fan-driven heat-dissipating function, and which is characterized by the provision of a special casing structure that allows the maximum allowable blade length of the fan unit to be increased as compared to the prior art, allowing the fan unit to provide an enhanced air blowing efficiency so that it can more efficiently blow away the heat produced by the server during operation.

摘要:
A radiator, adopted on electronic devices with radiator fans installed in series, includes a case, two or more radiator fans and a membrane check valve. The radiator fans are located on the inner wall surface of the case. The membrane check valve has a frame, at least one bracing bracket and membrane petals. The frame is located between the radiator fan and the inner wall surface of the case. The bracing bracket is located in the frame to form a plurality of cells with the frame. The membrane petals' one end attaches to one side of the frame and is more directed towards air outlets of the radiator fans than the bracing bracket. When any radiator fans stops operation, air inside the electronic devices flow outwards in the positive direction to balance the pressure and prevent heat dissipation efficiency of the electronic devices from dropping excessively.
