Patent number: 9759495Abstract: A battery cell assembly is provided. The battery cell assembly includes a battery cell and a heat exchanger disposed adjacent the battery cell configured to cool the battery cell. The heat exchanger has an outer housing. The outer housing defines an interior region and first and second flow guide members. The first and second flow guide members define a serpentine flow path in the interior region. The first and second flow guide members are tilted generally upwardly in the interior region. The serpentine flow path extends from an inlet aperture in the outer housing to another flow path in the outer housing. The another flow path extends from the serpentine flow path to an outlet aperture.Type: GrantFiled: June 30, 2008Date of Patent: September 12, 2017Assignee: LG Chem, Ltd.Inventors: Josh Payne, Igor Isayev, Heekook Yang, William Koetting, Peter Morris, Venkatachala Moorthi Natarajan

Patent number: 9083066Abstract: A battery system having first and second battery cells and a cooling fin disposed between the first and second battery cells is provided. The cooling fin receives heat energy from the first and second battery cells and transitions a two-phase refrigerant into a gaseous refrigerant within an internal flow path. The compressor pumps the gaseous refrigerant into a condenser. The condenser transitions the gaseous refrigerant into the liquid refrigerant by extracting heat energy from the gaseous refrigerant.Type: GrantFiled: November 27, 2012Date of Patent: July 14, 2015Assignee: LG Chem, Ltd.Inventors: Satish Ketkar, Robert Merriman, Michael Nielson, Igor Isayev
