Patent number: 7826215Abstract: A temperature isolation duct in a computer system comprising a chassis securing a circuit board and a fan system that draws air through the chassis, and a heat-generating component is mounted on the circuit board and exposed to the air flow. The hot air duct passively directs air heated by the heat-generating component from a single hot air duct inlet in direct downstream alignment with the heat-generating component to a single hot air duct outlet. A thermal sensor is secured within, or in direct alignment with, the hot air duct near the duct outlet for sensing the temperature of air flowing through the hot air duct and generating a temperature signal. A controller is in electronic communication with the thermal sensor for receiving the temperature signal and in electronic communication with the fan system for sending a fan speed control signal.Type: GrantFiled: February 15, 2008Date of Patent: November 2, 2010Assignee: International Business Machines CorporationInventors: Troy Williams Glover, Michael Sean June, Vinod Kamath, Whitcomb Randloph Scott, III

Patent number: 7724515Abstract: In a disk array apparatus, by taking note of a first sound of a specific frequency which is a noise element of original sounds generated from a fan, a second sound whose phase is inverted to that of the first sound is generated by a structure of a cooling air flow path passing through the fan, and the second sound is synthesized with the first sound on the cooling air flow path, thereby reducing the noise. For example, an exhaust duct is located on a fan unit in an upper part of the apparatus, two flow paths extending to an exhaust port are formed in an internal structure of the exhaust duct, and the two flow paths are designed so that the difference in the flow path length therebetween becomes equivalent to half wavelength of the specific frequency.Type: GrantFiled: January 23, 2008Date of Patent: May 25, 2010Assignee: Hitachi, Ltd.Inventors: Hiroshi Fukuda, Hitoshi Matsushima

Patent number: 7724516Abstract: Apparatus and methods for thermal conditioning equipment. In a preferred embodiment, an equipment enclosure comprises a body, a wall, a fluid port, and a fixture. The body defines an outer plenum and an inner chamber in the latter of which the fixture retains the equipment. The wall, which is between the outer plenum and the inner chamber, isolates the thermally conditioned first fluid from a second fluid in the inner chamber. Since the wall is thermally conductive it allows heat to be transferred between the outer plenum and the inner chamber. The fluid port is in communication with the outer plenum to allow the thermally conditioned first fluid to flow into the outer plenum. Baffle plates are also provided to distribute flow of the second fluid to the equipment.Type: GrantFiled: August 26, 2005Date of Patent: May 25, 2010Assignee: The Boeing CompanyInventors: Daniel Harder, Charles F.
