  • Thermal energy exchanger
    Patent number: 8256497
    Abstract: A thermal energy exchanger assembly (100) includes an exchanger housing (138). The exchanger housing (138) houses a pair of core support assemblies (174) formed of individual core supports (200). The core supports (200) are coupled together so as to form apertures 228. Core tubes (180) are received within the apertures (228). A fresh airstream (122) is made to flow through the core tubes (180) while a stale airstream (114) is made to flow between and around the core tubes (180). In this manner, an exchange of thermal energy occurs between the fresh airstream (122) and the stale airstream (114).
