  • Patent number: 6888725
    Abstract: Plural CPUs 20-1 through 20-6 are mounted on a circuit board 11, and heat sinks 30-1 through 30-6 are mounted on these CPUS, respectively. The CPUs 20-1 through 20-6 are cooled by an air flow generated by motor fan units 14-1, 14-2, 15-1, and 15-2. The CPUs 20-1 through 20-6 are arranged such that a ratio of a sectional clearance area at the downstream side of the air flow to a sectional area of a tunnel 12 is lower than a corresponding ratio at the upstream side of the air flow. This clearance is formed between a cover member 13 and the heat sinks 30-1 through 30-6. Air flow passages 85 and 86 are formed at both sides at the upstream side. By the air flow passages 85 and 86, the amount of fresh air that is sent to the heat sinks 30-5 and 30-6 at the downstream side is increased. Accordingly, the cooling of the CPUs 20-5 and 20-6 at the downstream side is promoted compared to the conventional case.

  • Patent number: 6798657
    Abstract: A cooling system that can be used, for example, for cooling electrical circuit boards housed in an equipment cabinet. The cooling system includes a flow-rate-amplifying pump configured to introduce ambient air into the cabinet. The flow-rate-amplifying pump is a passive device, which has a primary intake and a secondary intake and is designed to produce a large flow of relatively cool ambient air into the cabinet through the primary intake using a small volume of compressed air applied to the secondary intake. In one embodiment, the cooling system has an auxiliary pump driven by a windmill device. Rotation of a propeller in the windmill device is converted into piston oscillation in the auxiliary pump, which oscillation is used to compress air and apply it to the secondary intake of the flow-rate-amplifying pump. A cooling system of the invention can provide efficient cooling while being self-sustaining and generating less noise and/or electrical interference than prior art cooling systems.

  • Patent number: 5914858
    Abstract: A baffle arrangement, interposed between a series of modules of electronic components and a fan, helps to improve the evenness of flow of air drawn through the components by the fan. The baffle arrangement comprises a series of channels. A first half of the channels runs from one end of the series of modules, across approximately half of the modules. A second half of the channels runs from approximately half-way across the series of modules to the other end of the series of modules. There is a gap between each channel and an adjacent channel of approximately the width of a channel. The first half of the channels is offset from the second half of the channels by approximately the width of a channel such that no channel from the first half of channels is collinear with a channel from the second half of channels. Air drawn up from a module into a channel must flow along the channel to the end of the channel (approximately mid-way across the series of modules) before being drawn into the fan.

  • Patent number: 5746653
    Abstract: The apparatus can distribute and collect air. As a collector, a fan draws air from the proximal end of an elongated tube disposed in an air-environment. The tube is closed at the distal end but receives air all along its length through its air-permeable wall. The wall is more permeable to air at its distal end than at its proximal end. Wall permeability gradually increases from the proximal end to the distal end so that a substantially constant rate of air ingestion occurs at all points along the wall. A reversal of the airflow direction converts the air collector into an air distributor for distributing air evenly along its length.
