A load card for testing different types of PCI slots is provided. The load card includes several gold fingers, and resistor selection circuits. Each gold finger corresponds to one PCI slot. Each resistor selection circuit includes a resistor to test at least one PCI slot working in one working voltage. When a PCI slot working at a working voltage is to be tested, the gold finger connects to the PCI slot, and the resistor selection circuit including the resistor to test the PCI slot working at the working voltage is enabled and others are disabled in response to an operation of the user.

An air duct includes a top plate, two side plates extending from two lateral sides of the top plate, a baffle plate extending from the top plate and located between the side plates, and a torsion spring connected between the top plate and the baffle plate. The top plate and the side plates cooperatively define an air passage in the air duct. The baffle plate includes a first end pivotally connected with the top plate and an opposite second end. The second end of the baffle plate is rotatable relative to the top plate. The torsion spring includes two arms abutting against the top plate and the baffle plate, respectively. When the baffle plate is rotated relative to the top plate under an external force, the torsion spring resists such force.

A heat sink includes a base and a number of fins perpendicularly extending from the base. The base includes a main body. The fins include a number of parallel first fins and two second fins sandwiching the first fins. Each second fin includes a main piece extending from the main body and a guiding piece extending from one end of the main piece.

A container data center includes a portable container, a number of server cabinets accommodated in the container, a shutter set on a side wall of the container, a temperature sensor to sense a temperature of air outside the container, a humidity sensor to sense a humidity of air outside the container, and a controlling device to receive the sensed temperature and the sensed humidity. The controlling device compares the sensed temperature with a preset temperature and compares the sensed humidity with a preset humidity range. When the sensed temperature is less than the preset temperature and the sensed humidity is in the preset humidity range, the controlling device opens the shutter. When the sensed temperature is higher than the preset temperature or the sensed humidity is outside of the preset humidity range, the controlling device closes the shutter.

A heat dissipation device is for dissipating heat generated from an electronic device, and includes a fan duct and a heat sink. The fan duct includes a top plate having a receiving hole penetrating therethrough. The heat sink is configured to dissipate heat from a heat-generating electronic component of the electronic device, and includes a base configured to be mounted on the heat-generating electronic component and a number of heat dissipating sheets positioned on the base. The heat dissipating sheets are long enough to extend towards the fan duct and into the receiving hole when the heat dissipation device is installed in the electronic device.

An exemplary server system includes a server cabinet, multiple racks arranged in the server cabinet, multiple servers mounted on the racks, and a heat dissipation device for cooling the servers. The heat dissipation device includes a fan module and a dissipating module. The fan module is arranged over the racks for generating downwards airflow across the servers to exchange heat with the servers. The dissipating module is arranged over the racks to exchange heat with the airflow after the airflow passes the servers.

An exemplary server system includes a server cabinet, racks arranged in the server cabinet, servers mounted on the racks, and a heat dissipation device. The heat dissipation device includes a heat exchanger arranged over the racks, a first fan module arranged under the racks for drawing cooling air from the heat exchanger to the servers to exchange heat, and a second fan module including drawing fans respectively arranged on the racks for drawing up heated air from the servers to the heat exchanger.

A heat dissipation apparatus adapted for cooling an electronic component received in a metal housing includes a heat sink thermally attached to the electronic component and a plurality of resilient tabs arranged between the heat sink and the metal housing. The resilient tabs are elastically deformed by the metal housing and thermally contact an inner face of the metal housing.

A data center includes a housing and a number of server module assemblies received in the housing. Airflow interspaces are formed between neighboring server module assemblies, and between the two outmost server module assemblies and corresponding sidewalls of the housing. The airflow interspaces are alternately used for cold aisles and hot aisles. An inside of each server module is communicated with one of the hot aisles and one of the cold aisles at opposite sides of the server module. A number of cooling units are installed in the housing over the server module assemblies. A number of fans are installed in the housing to draw hot air from the hot aisles to flow through the corresponding cooling units to be cooled, and the cooled air flow into the corresponding cold aisles, thereby creating air differences in air pressure between the cold aisles and the hot aisles.
摘要:
A container data center includes a container and a number of server systems arranged in two rows. The container includes a top wall, a bottom wall opposite to the top wall, and opposite sidewalls connected between the top wall and the bottom wall. Each of the sidewalls defines an intake adjacent to the bottom wall of the container, and an outlet adjacent to the top wall of the container. Air outside the container is drawn into the container through the intake to cool the server systems. Hot air dissipated by the server systems is exhausted out of the container through the outlet of the container.
