EXHAUST HEAT RECOVERY AND STORAGE SYSTEM

摘要

A product is disclosed for recovering heat and may include a housing with two flow paths defined through the housing. A number of tube assemblies may be disposed in the housing. The tube assemblies may comprise an inner tube and an outer tube with a space defined between the inner tube and the outer tube. One flow path may be defined through the inner tubes, and the other flow path may be defined outside the outer tubes. A phase change material may be disposed in the spaces of the tube assemblies. The phase change material may change phases when exposed to a temperature change.
