  • Patent number: 10415903
    Abstract: A fluid cooled cold plate includes a main coolant passage with a first cross-sectional area taken laterally in a direction perpendicular to the flow direction and a finned coolant passage having a second cross-sectional area taken laterally in a direction perpendicular to the flow direction, with the second area smaller than the first area. Fluidly connecting the main coolant passage with the finned coolant passage is a branch oriented such that a fluid is turned 90° or more when passing into the branch from the main coolant passage. Also included is a coolant bypass passage in fluid communication with the main coolant passage and located fluidically parallel to the finned coolant passage.

  • Publication number: 20190215951
    Abstract: A system for reducing low cycle fatigue of a soldered connection includes a controller and a heating element operatively connected to the controller. The system also includes a printed wire board soldered in connection with an electronic component. The controller is configured to retrieve a signal indicative of a temperature of the electronic component, and compare the temperature to a stored predetermined range of operating temperatures. Responsive to determining that the temperature of the electronic component is less than a lower threshold temperature of the predetermined range of operating temperatures, the controller transmits a signal to the heating element that causes the heating element to heat the electronic component. The controller then saves, to an operatively connected computer readable memory, a magnitude of temperature difference and a number of times that magnitude is reached. The controller uses the stored information to track the life of the electronic component.

  • Publication number: 20160113147
    Abstract: A system for cooling an electronics box includes an electronics box with a first portion and a second portion. During a low load condition on the electronics box the first portion and the second portion require a substantially similar amount of cooling air and during a high load condition on the electronics box the second portion requires a substantially greater amount of cooling air than the first portion. The system further includes a first plenum in fluid communication with the first portion and a second plenum in fluid communication with the second portion. A normal cooling air supply is in fluid communication with both the first plenum and the second plenum during the low load condition on the electronics box, and a supplemental cooling air supply in fluid communication with the second plenum during the high load condition on the electronics box.
