Disclosed is system, method, and rack stand portion for the advantageous cooling of computer equipment 305. The rack stand 200 includes a hollow body 210, 212 that may be formed of cartridges 2416. Gas from an airflow source 5204 is guided into the rack stand body and then into a sealed case of the computer equipment. Air flow is then guided out of the computer equipment for recirculation, exhaust, or other purpose.

Foreign matter is prevented from entering the inside of an electronic apparatus. An electronic apparatus (100) includes plural exhaust holes (E1, E2) formed in an armor member (20), an air flow path (S3) formed inside the armor member (20) and connected to the plural exhaust holes (E1, E2), a power source circuit (41) disposed in the air flow path (S3), and a foreign matter preventing member (70) located between the power source circuit (41) and the plural exhaust holes (E1, E2). The foreign matter preventing member (70) is formed with plural openings (Es). Each of the openings (Es) is smaller in size than each of the exhaust holes (E1, E2).

A frame having a perimeter defines a planar opening. A set of louvers may span from a first edge of the opening to a second edge of the opening. Each louver may be capable of rotating between a closed position and an open position. A set of physical obstructions may prevent the louvers from rotating beyond the open position. Each louver may be offset from the planar opening by a first acute angle when in a closed position, and by a second, larger, acute angle when in the open position. A flow of air in a first direction through the opening may rotate the set of louvers to the closed position. A flow air in the opposite direction through the opening may rotate the set of louvers to the open position such that the flow of air in the opposite direction moves freely through the opening.

An electronic product, including: a housing, where an air vent is disposed on the housing; a PCB board that is located inside the housing, where a positive electrode and a negative electrode of a power supply are disposed on the PCB board; a fan that is located between the PCB board and the housing; and a switch bar that is located between the fan and the housing and is connected to the housing in a sliding manner, where the switch bar has a first state and a second state, where the switch bar includes a conductive area, when the switch bar is set to the first state, the conductive area is electrically connected to the positive electrode and the negative electrode of the power supply on the PCB board, the fan starts to run.

A system includes a cabinet having a first wall, a second wall opposite the first wall, and a back wall extending from the first wall to the second wall. The system also includes a flow plate disposed at least partially within the cabinet and partitioning the inner space into a first portion and a second portion. The system also includes a shelf disposed at least partially within the first portion of the inner space, and a flow device fluidly connected to the cabinet. The flow device is configured to remove air from the first portion of the inner space, and the flow plate is configured to substantially prohibit removal of air by the flow device from the second portion, via the first portion, when the cabinet is in a closed condition.

An electronic device including an electronic module, a casing, and at least one air port is provided. The casing accommodates the electronic module. The air port is disposed on the casing to communicate the inside of the box to the outside. The air port includes an inclined blocking element. The inclined blocking element has a plurality of inclined openings, and the inclined openings are inclined relative to a horizontal direction.

An air flow distribution system for a plurality of fans includes an air collimator that is operable to pass a flow of air in a linear vertical direction, thereby creating an improved optimal flow direction for cooling device components. The air collimator includes air transfer diverters to redirect swirling air from a fan into a linear flow, thereby increasing the cross-sectional air flow distribution throughout the device being cooled. Self-activating, separately controlled plurality of louver systems automatically close upon failure of an associated one of a plurality of cooling fans to prevent air from recirculating back through the failed fan. Therefore, air continues to move in a linear direction across the device components such that the device components remain at a specified temperature.

According to one embodiment, an electronic apparatus includes a housing having an internal space, a fan provided inside the housing, a ventilation flue provided inside the housing to circulate air in the internal space, the air emitted from the fan and to guide the air to a suction opening of the fan, and a heat generator provided in a path of a flow of the air.

The present invention includes a lateral support member for a server computer constructed to permit advantageous airflow. The present invention can be operated to shunt organized airflow into multiple computer cases and/or organized airflow from multiple computer cases to a dedicated heat reservoir.

A filter housing can support filter media for a fan arrangement. The filter housing can include a filter body with a first opening at a first end and a second opening at a second end. A bell portion can be disposed between the air inlet opening and the air outlet opening and can define a cavity within the housing body. An air-permeable filter support can extend into the cavity to support the filter media within the cavity, with the filter media spaced apart from at least one of the first and second openings.
