摘要:
A cable connector system includes an electrical cable (having a primary conductor and an insulation layer), a connector, a flow block member and a flowable sealant. The primary conductor of the cable extends into a conductor bore of the connector through a passage in the flow block member and is mechanically and electrically coupled to the connector. The flow block member is thereby mounted on the primary conductor and interposed between a terminal end of the insulation layer and an end face of the connector. The sealant surrounds the flow block member and adjacent portions of the insulation layer and the connector. The flow block member inhibits flow of the sealant into the conductor bore through the entry opening.

A server cabinet is provided, which not only utilizes a first cooling fluid to flow through a heat exchanger of the cabinet to lower the temperature of entrances of fan modules without wasting additional energy, but also utilizes a cooling fluid pipe set to send a second cooling fluid to heat exchange apparatuses in a server to lower the temperature of heating elements inside the cabinet. The server cabinet could lower the heat dissipating loading of the heat exchanger of the cabinet and achieve the efficiency of saving energy.

A server cabinet includes a rack, at least one assembling frame, a radiator and at least one fan. The rack has a first frame and a second frame opposite to each other. The assembling frame and the radiator are mounted on the first frame in sequence. The radiator transfers a coolant to flow inside a plurality of heatsink fins thereof in a circulating manner. The fan is mounted in the assembling frame, and the fan guides an airflow to flow into the first frame from the radiator, and blows the airflow in the rack to the second frame, thus lowering the temperature inside the rack.

A cooling circulation system of a server includes a cabinet assembly, a plurality of first fan modules, a plurality of second fan modules, and two air guide hoods. The first fan modules and the second fan modules are disposed on the cabinet assembly. The first fan modules blow a first airflow towards a first direction, and the second fan modules blow a second airflow towards a second direction. The air guide hoods are respectively installed on two ends of the cabinet assembly. The first airflow and the second airflow join each other through the air guide hoods, so as to form a cooling circulation loop inside the cabinet assembly.

A heat exchange chamber for liquid state cooling fluid is provided, which comprises a flow resistance, the flow resistance is sited inside a cavity at a position proximate to an inlet. In other words, the flow resistance is sited between the inlet and a thermal dissipation device. The flow resistance narrows down a flow channel from the inlet to the cavity, and it raises the resistance of the cooling fluid before the cooling fluid flows through a thermal dissipation device. Because of the heat exchange chamber for liquid state cooling fluid, the cooling fluid could be distributed uniformly through the dissipating heat device.

A current-sharing power supply apparatus is applied to regulate voltage level of an input DC voltage, and the regulated DC voltage is stabilized in a predetermined voltage to be used on rear-end circuits. The current-sharing power supply apparatus includes a square-wave generating circuit, a rectifier circuit, a conversion circuit, a rectifier circuit, a filter circuit, a first output terminal, and a second output terminal. The current-sharing power supply apparatus provides two output voltages with a multiple relation from the first output terminal and the second output terminal, respectively.

A light emitting diode (LED) driving device is used to drive an LED module. A conductive current flows through the LED module when the LED module is driven. The LED driving device includes a driving-controlling unit and a current-regulating unit. The driving-controlling unit is driven by a controllable current. The current-regulating unit is electrically connected to the LED module and the driving-controlling unit. The current-regulating unit divides the branch of the conductive current into two branches, and controls the current flowing through one of the branches to be proportional to the controllable current. Therefore, the current-regulating unit provides a stable current to the driving-controlling unit and prevents the driving-controlling unit from an overcurrent damage.
