Methods Of Preventing Freezing Of Relays In Electrical Components

View page
US Patent:
20130181732, Jul 18, 2013
Filed:
Jan 13, 2012
Appl. No.:
13/350009
Inventors:
Greg Szleszynski - Troy MI, US
Adrian Dobre - West Bloomfield MI, US
Teofil Barjuca - West Bloomfield MI, US
Ryutaro Mine - Farmington Hills MI, US
Jim Beach - Plymouth MI, US
Adam Wehner - South Lyon MI, US
Tim Balogh - Waterford MI, US
Assignee:
NISSAN NORTH AMERICA, INC. - Franklin TN
International Classification:
G01R 31/00
US Classification:
32475003
Abstract:
Disclosed herein are methods of preventing freezing of relays in electrical components operated in specific atmospheric conditions. One such method described herein comprises monitoring a temperature of a relay with a thermocouple located on a contact of the relay while monitoring ambient temperature within the relay. Operation of the electrical component is simulated in a sub-zero temperature and high humidity condition. A freeze potential of the relay is determined by plotting a temperature cross-over curve, wherein both the ambient temperature and the contact temperature are plotted during the operation and cool down period. If the high freeze potential is determined, one or both of the relay and the electrical component are modified with a modification configured to decrease the high freeze potential.

US Patent:
20130181059, Jul 18, 2013
Filed:
Jan 13, 2012
Appl. No.:
13/350056
Inventors:
Greg Szleszynski - Troy MI, US
Adrian Dobre - West Bloomfield MI, US
Teofil Barjuca - West Bloomfield MI, US
Adam Wehner - South Lyon MI, US
Ryutaro Mine - Farmington Hills MI, US
Tim Balogh - Waterford MI, US
Jim Beach - Plymouth MI, US
Assignee:
NISSAN NORTH AMERICA, INC. - Franklin TN
International Classification:
F24F 3/14
US Classification:
236 44 C
Abstract:
Disclosed herein are embodiments of testing apparatus used to prevent freezing of relays in electrical components, particularly electrical components used in vehicles. One embodiment of a testing apparatus comprises a chamber with temperature control configured to control a temperature of an internal atmosphere of the chamber and a humidifier in fluid communication with the internal atmosphere of the chamber configured to supply humidified air to the internal atmosphere. A sealable opening in a wall of the chamber is configured to pass a wire harness from external the chamber to inside the chamber while maintaining a sealed environment within the chamber. The temperature control is configured to maintain a sub-zero temperature in the internal atmosphere while the humidifier maintains a saturated internal atmosphere.
