Publication number: 20140177673Abstract: Scale deposition on a heat transfer surface in a liquid system such as a heat exchanger is estimated by directing of small portion of the liquid flow through a test cell, consisting of a sensor positioned on and projecting through a conduit wall. The sensor consists of a conductive block containing a heater and having a heated wetted test surface that is flush with the inside of the conduit wall and in contact with the flow through the conduit. Within the conductive block are two temperature sensors which are at different distances from the heated wetted test surface and the heater. The periphery of the apparatus is designed to reduce heat flow through the periphery and allow greater heat flow through the heated wetted test surface. By comparing the temperature differential between the two temperature sensors to the differential when no scale is present, the presence of and amount of scale can be determined, based on reduced heat transfer through the heated wetted surface caused by the accumulated scale.Type: ApplicationFiled: December 13, 2013Publication date: June 26, 2014Applicant: HERCULES INCORPORATEDInventors: TERRY LYNN BLISS, TIMOTHY FREDERICK PATTERSON

Publication number: 20140148982Abstract: A thermal system includes fluid-cooled devices, a controller, and a thermal loop or loops each having a cooling actuator and fluid passages. The controller executes device-specific control logic to arbitrate between cooling requests having different relative priorities. The controller receives raw speed requests and noise, vibration, and harshness (NVH) limits for each device, and processes the raw speed requests and NVH limits to determine a relative cooling priority for each device. The controller outputs a speed command to the actuator(s) for each thermal loop in order to cool the devices at a level required by the device having the highest relative cooling priority. A vehicle includes a traction motor, a transmission that is selectively connected to the traction motor, fluid-cooled devices each in electrical communication with the motor, and a controller configured to execute the arbitration method noted above.Type: ApplicationFiled: November 29, 2012Publication date: May 29, 2014Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Christopher D S Ballnik, Xiaowen Luo, Keith D.
