Patent number: 8636406Abstract: An apparatus determines cooling characteristics of an operational cooling device used for transferring heat from an electronic device. The operational cooling device is thermally coupled to a heat pipe. The heat pipe has an exposed surface for selective application of heat thereon. Heat from a localized heat source is selectively applied to at least one region of the exposed surface. The heat source is preferably capable of being varied both positionally relative to the exposed surface and in heat intensity. A heat shield is preferably positioned around the exposed surface of the heat pipe to isolate the operational cooling device from the heat from the localized heat source. A temperature detector repeatedly measures a temperature distribution across the exposed surface while the cooling device is in a heat transfer mode. The temperature distribution is then used to thermally characterize the operational cooling device.Type: GrantFiled: April 12, 2012Date of Patent: January 28, 2014Assignee: International Business Machines CorporationInventors: Hendrik F.

Patent number: 8038343Abstract: A novel computer program product and method for thermally characterizing a device used for cooling an electronic device is disclosed. A cooling device, being operated, is thermally coupled to a heat pipe having a surface to receive a test chip. A heater is patterned on a circuitry side of the test chip. The heater is separate from operational circuitry of the test chip. A localized heat source is applied to at least one region on a test chip thermally coupled to the heat pipe to locally heat more than one region on a second surface of the test chip to test more than one hot spot. The second surface is the circuitry side of the test chip. The heater provides a bias heat to the test chip, independent of operating the test chip, while the localized heat source is selectively applied directly to the test chip. A temperature detector is used to measure a temperature distribution on the second surface of the test chip.Type: GrantFiled: March 14, 2008Date of Patent: October 18, 2011Assignee: International Business Machines CorporationInventors: Hendrik F.

Patent number: 7698114Abstract: Techniques for enhancing thermal design of a system having a number of boundary values are provided. A method for such enhancement includes representing thermal response of the system to the boundary values, obtaining at least one constraining parameter, and determining spatial and/or temporal distribution of the boundary values. The thermal response is represented as a superposition of temperature fields associated with given boundary values. The spatial and/or temporal distribution of the boundary values is determined based on the thermal response represented in the representing step, so as to satisfy the constraining parameter. The boundary values can be, for example, power sources, and the at least one constraining parameter can be, for example, a spatial or temporal location of one of the power sources.Type: GrantFiled: November 2, 2005Date of Patent: April 13, 2010Assignee: International Business Machines CorporationInventors: Hendrik F.

Patent number: 7167806Abstract: A present invention provides real-time temperature and power mapping of fully operating electronic devices. The method utilizes infrared (IR) temperature imaging, while an IR-transparent coolant flows through a specially designed cell directly over the electronic device. In order to determine the chip power distributions the individual temperature fields for each heat source of a given power and size on the chip (as realized by a scanning focused laser beam) are measured under the same cooling conditions. Then the measured chip temperature distribution is represented as a superposition of the temperature fields of these individual heat sources and the corresponding power distribution is calculated with a set of linear equations.Type: GrantFiled: August 17, 2004Date of Patent: January 23, 2007Assignee: International Business Machines CorporationInventors: Hendrik F.
