Abstract
A cooling system for an electronic device having a plurality of multistage circuit boards therein includes a plurality of inlet-side guides arranged in parallel on an inlet port side of the plurality of circuit boards in a direction of a flow of the air taken in from an inlet port. The inlet-side guides are each inclined at a predetermined angle toward a side opposite to the inlet port to deflect the inlet air away from the circuit boards. A plurality of fans blow onto the circuit boards the air guided by the plurality of inlet-side guides. The system may further include a mesh member between the circuit boards and the fans.
Claims22
An electronic device cooling system comprising:
- a cabinet;
- a plurality of circuit boards, installed in said cabinet, having electronic parts thereon;
- an inlet port through which air is taken into said cabinet;
- and
- a plurality of inlet-side guides, arranged in parallel on an inlet port side of said plurality of circuit boards in a direction of a flow of the air taken in from said inlet port, guiding said air taken in from said inlet port away from said plurality of circuit boards.
An electronic device cooling system comprising:
- a cabinet;
- a plurality of circuit boards, installed in said cabinet, having electronic parts thereon;
- an inlet port through which air is taken into said cabinet;
- a plurality of inlet-side guides, arranged in parallel on an inlet port side of said plurality of circuit boards in a direction of a flow of the air taken in from said inlet port, guiding said air taken in from said inlet port;
- and
- a plurality of fans blowing onto said circuit boards the air guided by said plurality of inlet-side guides, wherein said fans are arranged between said circuit boards and said inlet-side guides.
An electronic device cooling system comprising:
- a cabinet;
- a plurality of circuit boards, installed in said cabinet, having electronic parts thereon;
- an exhaust port through which air is exhausted from said cabinet;
- a plurality of exhaust-side guides, arranged in parallel on an exhaust port side of said plurality of circuit boards in a direction of a flow of the air exhausted from said exhaust port and each inclined at a predetermined angle toward said exhaust port, guiding the air warmed by said electronic parts on said circuit boards;
- and
- a plurality of fans exhausting the air warmed by said electronic parts on said circuit boards from said exhaust port via said plurality of exhaust-side guides, said fans being between said circuit boards and said exhaust-side guides.
An electronic device cooling system comprising:
- a cabinet;
- a plurality of circuit boards, installed in said cabinet and having electronic parts thereon;
- an inlet port through which air is taken into said cabinet;
- a plurally of inlet-side guides, arranged in parallel in a direction of a flow of the air taken in from said inlet port and each inclined at a predetermined angle toward a side opposite to said inlet port, guiding the air taken in from said inlet port away from said plurality of circuit boards;
- a plurality of first fans blowing onto said circuit boards the air taken in through said inlet port and guided by said plurality of inlet-side guides;
- an exhaust port through which the air is exhausted from said cabinet;
- a plurality of exhaust-side guides, arranged in parallel in a direction of a flow of the air exhausted from said exhaust port and each inclined at a predetermined angle toward said exhaust port, guiding the air warmed by said electronic parts;
- and
- a plurality of second fans exhausting the warmed air from said exhaust port via said plurality of exhaust-side guides.
An electronic device cooling system, comprising:
- a cabinet containing a plurality of generally parallel circuit boards and having an air inlet opening with an inlet axis that defines an inlet air path that is generally perpendicular to said plurality of circuit boards, an inlet air speed in the inlet air path decreasing as a distance from said air inlet opening increases;
- and
- a plurality of inlet air guides that extend into the inlet air path at an angle that deflects inlet air away from said plurality of circuit boards.
