Publication number: 20100186424Abstract: A heat exchange unit is constituted of a thermoelectric module and a heat exchanger. The thermoelectric module includes an upper electrode, a lower electrode, and a plurality of thermoelectric elements interposed between the upper electrode and the lower electrode, wherein the heat exchanger composed of aluminum or aluminum alloy having high thermal conductivity is attached to the upper electrode and/or the lower electrode via an insulating layer. The surface roughness of the heat exchanger adjoined to the insulating layer is controlled to be less than 4.7 ?m and greater than 0.1 ?m. This prevents cracks and fractures from being formed in the insulating layer, which is thus improved in adhesion with the heat exchanger. Thus, it is possible to demonstrate high heat-absorption/dissipation performance and high reliability in the heat exchange unit due to a reduced thermal resistance between the thermoelectric module and the heat exchanger.Type: ApplicationFiled: January 27, 2010Publication date: July 29, 2010Applicant: Yamaha CorporationInventor: YUMA HORIO

Publication number: 20100186430Abstract: A method and system for detecting a low charge condition in an air conditioner for a vehicle. The system first determines whether noise factors are present that would interfere with reliably measuring a pressure delta. If noise factors are not present, the system determines a pressure delta value for the compressor by comparing the high side pressure when the clutch is engaged to a high side pressure when the clutch is disengaged. If the pressure delta value is less than a threshold value, a low charge condition may be recorded. When the number of low charge conditions detected exceeds a predetermined number of events, the system may set a temperature diagnostic trouble code, disable the air conditioning system and alert the driver of a potential problem.Type: ApplicationFiled: January 26, 2009Publication date: July 29, 2010Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: William Stewart Johnston, David Alan Wong, Hugh Hamilton, Manfred Koberstein, Debasish Dhar
